Fitzgerald Flashcards
In counseling women about the use of a SSRI during pregnancy, the NP considers that studies to date reveal:
As more and more data become available about the effects of SSRI use during pregnancy, it has become apparent that there is a small but persistent increased risk of pulmonary hypertension in the exposed neonates. There is no link to neural tube defects, macrosomia, of gestational diabetes.
In the pregnant woman with asthma, in what part of her pregnancy are symptoms and bronchospasm likely to worsen?
29-36 weeks EGA
Bronchospasm can be triggered as a consequence of increased external pressure on the smooth muscle of the bronchial structures. The increasing size of the fetus during weeks 29–36 creates significant displacement of abdominal and thoracic structures and places external pressures on the bronchi. In the last four weeks, as the fetus “drops” into the pelvis, pressure on the bronchi is actually relieved a bit and symptoms often improve.
Medications most commonly pass through the placenta via:
Passive diffusion
The placenta is freely permeable and most medications that are administered to the mother just pass through the placenta along their concentration gradient until a steady state is achieved (i.e., passive diffusion). Facilitated transport and mechanical carrier state are mechanisms by which a medication requires another compound to allow the drug to pass through the membrane barrier. Pump actions are required when a medication or other compound is being actively pumped across a membrane against its concentration gradient.
When treating a woman with a UTI who is 22-weeks pregnant, the NP prescribes:
Nitrofurantoin (Macrobid)
In both the pregnant and non-pregnant woman, E. coli is the most common cause of uncomplicated UTI. Nitrofurantoin is a recommended first-line agent during pregnancy (pregnancy category B).
In treating a pregnant woman with acute bacterial rhinosinusitis, the NP would prescribe ______ and likely avoid prescribing_______
RX: amoxicillin, azithromycin
AVOID: Levofloxacin
Levofloxacin is pregnancy category C and would not be used when safer, effective alternatives are available. Amoxicillin and azithromycin are both indicated for acute bacterial rhinosinusitis (ABRS) and are pregnancy category B.
The recommended duration of antimicrobial therapy for treatment of a urinary tract infection in a pregnant woman is:
7 days
UTIs are common during pregnancy and the most common causative pathogen is Escherichia coli. In pregnancy, hormonal changes and dilation of the renal pelvis actually favor ascension into the upper urinary tract and, therefore, UTI is treated aggressively. Because of the dangers of maternal and fetal complications from a UTI during pregnancy, a 7-day regimen of antimicrobial therapy is recommended to ensure eradication of the bacteria.
The most likely causative organism in uncomplicated UTI during pregnancy is:
escheria coli (E. coli)
In both the pregnant and non-pregnant woman, E. coli is the most common cause of uncomplicated UTI. The organism is a common intestinal inhabitant and the close proximity of the anus and urethra puts women at risk for ascension of the organism into the lower urinary tract. In pregnancy, hormonal changes and dilation of the renal pelvis actually favor ascension into the upper urinary tract and, therefore, UTI is treated aggressively.
When a pregnant woman takes a teratogenic drug, the fetal effects are usually seen in what pattern:
Certain target organs in a predictable manner
Most teratogenic drugs target particular organ systems, and so the embryo or fetus is most vulnerable at very specific times during development. Injury is not systemic, but rather organ-system specific and predictable.
The release of which chemical mediator causes primary dysmenorrhea?
prostaglandins
Dysmenorrhea (painful menstruation) is classified as primary (from the onset of menstruation) or secondary (due to some physical cause and usually of later onset). Primary dysmenorrhea is due to the production of prostaglandins made by cells in the inner lining of the uterus. Prostaglandins cause the uterine muscles to contract and help the uterus shed the lining that has formed during the menstrual cycle. If excessive prostaglandins are produced, the woman can experience excessive pain with her menstrual cycle.
General pathogenic mechanisms of polycystic ovarian syndrome
PCOS is a result of a combination of conditions that include oligoovulation or anovulation, elevated levels of androgens, or clinical signs of hyperandrogenism and polycystic ovaries.
Polycystic ovarian syndrome (POS or PCOS) is associated with abnormalities in the metabolism of androgens and estrogen and in the control of androgen production. Patients typically have high serum concentrations of androgens, including testosterone, androstenedione, and dehydroepiandrosterone sulfate (DHEAS). POS is also associated with peripheral insulin resistance and hyperinsulinemia. In POS, oligoovulation or anovulation can occur, leading to the production of cysts in the ovaries that can contribute to infertility.
Considering the mediating factors of premenstrual syndrome (PMS), which medication can be used either continually or only during the menstrual period luteal phase of the menstrual cycle as a treatment for the condition?
Select SSRIs
Evidence implicates the serotonergic system is involved in the pathogenesis of premenstrual syndrome and its most intense form, premenstrual dysphoric disorder (PMDD). As a result, SSRIs are considered the most effective pharmacologic class for the treatment of PMS symptoms, such as irritability and depressed mood. SSRIs can be taken continuously or in the luteal phase of the menstrual cycle (the two weeks leading up to menstruation).
When a woman’s uterus is assessed as protruding into the vagina to the hymen, which stage of prolapse does this indicate?
Stage 2
Uterine prolapse is the downward displacement of the uterus into the vaginal canal taking the vaginal wall with it. 1st degree = cervix drops into lower part of the vagina; 2nd degree = the body of the uterus lies in the vagina; cervix is at the vaginal opening; and 3rd degree = the uterus and cervix protrude through the vaginal introitus.
Which term is used to identify the descent of the posterior bladder and trigone into the vaginal canal?
cystocele
Prolapses can occur in the anterior, middle, or posterior compartment of the pelvis. A cystocele comprises of a prolapse of the bladder into the vagina. An enterocele is a herniation of the pouch of Douglas (including small intestine/omentum) into the vagina. A rectocele is a prolapsed of the rectum into the vagina. A vaginocele (or colpocele) occurs when the base of the vagina drops from its normal position in women who have previously undergone a hysterectomy.
What type of cyst develops when an ovarian follicle is stimulated but no dominant follicle develops and completes the maturity process?
benign ovarian cyst
Many women will develop at least one ovarian cyst during their life with most cases being asymptomatic and resolving on their own. A benign ovarian cyst develops when a follicle is stimulated but no dominant follicle develops and completes the maturation process
What is a follicular cyst?
A follicular cyst occurs when the sac surrounding the egg fails to break open to release the egg, with the resulting fluid forming a cyst.
What is a corpus albicans cyst
A corpus albicans cyst is typically a small hyalinized fibrous scar, sometimes with fluid, that develops after the corpus luteum involutes.
What is a corpus luteum cyst
Corpus luteum cysts occur when the follicle sac fails to dissolve after releasing the egg, thus sealing the opening and allowing accumulation of fluid to form the cyst.
Which description is used when a progressive neoplastic change involves the full epithelial thickness of the cervix?
Cervical carcinoma in situ (Stage 0)
Cervical dysplasia refers to abnormal changes in the cells on the surface of the cervix. Cervical dysplasia that is seen on a Pap smear is called a squamous intraepithelial lesion (SIL). If an SIL is detected, a biopsy is often needed for confirmation. A dysplasia seen on biopsy of the cervix is called cervical intraepithelial neoplasia (CIN), and these are grouped into 3 categories (I, II, III) based on severity. A progressive neoplastic change that involves the full epithelial thickness of the cervix describes cervical carcinoma in situ (CIS), or stage 0 cervical cancer. At this stage, the cancer is noninvasive and confined to the surface of the cervix.
Which benign breast tumor affects postmenopausal women and is characterized by the principal lactiferous ducts becoming dilated and filled with cellular debris?
mammary duct ectasia
Mammary duct ectasia most often affects women in their 40s and 50s and is caused by inflammation of the ducts behind the nipple, causing the ducts to become clogged with thick, sticky cellular debris. Intraductal papillomas consist of small wart-like growths that project into lactiferous ducts near the nipple and usually affect women 30–50 years of age. Phyllodes tumors are rare breast tumors most common in women in their 30s and 40s.
When ovarian cancer is associated with a known pattern of inheritance, the majority are associated with:
BRCA 1
Data from the National Cancer Institute show that, though only about 1.4% of women in the general population will develop ovarian cancer over their lifetimes, 39% of those with a BRCA1 mutation will develop ovarian cancer by age 70 years. This compares with 11– 17% of women with a BRCA2 mutation. The USPSTF recommends screening women who have family members with breast, ovarian, tubal, or peritoneal cancer with one of several screening tools designed to identify a family history that can be associated with an increased risk for BRCA1 or BRCA2 mutations.
Risk for ovarian cancer with BRCA 1 vs. 2
BRCA 1 = 39-44%
BRCA2 = 11-17%
Which is worse, BRCA 1 or 2?
BRCA 1
Risk for breast cancer with BRCA 1 vs. 2
BRCA 1 = 55%–72%
BRCA 2 = 45%–69%
Anovulatory bleeding is abnormal uterine bleeding resulting from (2)
- estrogen excess
- progesterone deficiency
Anovulatory bleeding results from a disruption in the normal cyclic pattern of ovulatory stimulation to the endometrial lining. The bleeding in these patients is unpredictable (heavy or light, short or prolonged, frequent or random). As a result of cyclic disruption, patients have constant, non-cycling estrogen levels along with progesterone deficiency (as this is normally released during the luteal phase) that stimulates endometrial growth.
The size of benign uterine tumors, such as leiomyomas, is thought to be caused by the influence of which hormone(s)? (Select all that apply.)
- estrogen
- progesterone
- growth factors
Benign uterine tumors, or fibroid tumors, are non-cancerous and comprised of fibrous tissue. Tumors can range in size and number, and can range from 1 mm to more than 20 cm in diameter. The cause of these tumors is not completely understood, but most develop in women during their reproductive years, but not before the production of estrogen. Hence, estrogen as well as progesterone and other growth factors can influence tumor size. Any association of luteinizing hormone (LH) or gonadotropin-stimulating hormone (GnRH) on tumor size has not been demonstrated.
What are the two most common clinical manifestations of endometriosis?
- infertility
- dysmenorrhea
Endometriosis occurs when endometrial cells grow outside the uterus, most commonly involving the ovaries, bowel, and tissue lining the pelvis. Most women with endometriosis have no symptoms. However, those with symptoms can experience dysmenorrhea, pain with intercourse, pain with bowel movements or urination, and excessive bleeding. Infertility is a common consequence of the condition. Other symptoms can include fatigue, diarrhea, constipation, and bloating and nausea, especially during menstrual periods.
When caring for a patient with alpha thalassemia minor, the nurse practitioner knows that primary care should include:
offering genetic counseling prior to pregnancy
Alpha thalassemia minor is an inherited genetic abnormality in one or both of the alpha chains of the hemoglobin protein. Two parents with alpha thalassemia minor can produce an offspring with the most serious form of the disease and genetic counseling is imperative. Since alpha thalassemia minor is not a product of micronutrient deficiency, supplementation is not indicated and in some cases (as with iron) can be dangerous. Hemoglobin electrophoresis identifies the form of hemoglobin, which does not change over time.
What is alpha thalassemia minor and how is it diagnosed
inherited hemoglobinopathy, genetic abnormality in one or both of the alpha chains of the hemoglobin protein»_space; leads to anemia
diagnosed with RBC electrophoresis
alpha thalassemias occur most commonly in patients of _____ origin, whereas beta thalassemias are predominant in patients of ______ descent
Alpha = Asian, African Beta = Mediterranean
Pollen counts are highest in the _________ and allergy sufferers are advised to stay indoors and keep windows closed as much as possible during these hours in order to minimize exposure
early morning hours (5:00 a.m. to 10:00 a.m.)
Classic finding at the onset of herpes zoster
A 1–2 day prodrome of pain prior to lesions erupting
You see a 14-year-old girl at Tanner stage 2–3 who complains of being the shortest in her class. You advise:
that her growth spurt will start soon
The adolescent growth spurt does not occur until Tanner stage 3, so this patient has not reached that point in her physical development. Having reached Tanner stage 2–3 by the age of 14 reassures the nurse practitioner that the patient’s puberty is progressing appropriately. The best response is to tell her that she has not achieved her growth spurt yet, but that it will likely begin soon. Referral to an endocrinologist or for a bone age evaluation is not appropriate for this patient as her developmental pattern is consistent with normal expectations.
Adolescent growth spurt does not occur until Tanner Stage….
Stage 3
Tanner Stage 1
~age 8yo
pre-adolescent, no noticeable changes
early pulsatile signals beginning from HPO-axis
Tanner Stage 2
~ages 9-11yo
Breast “buds” start to form; pubic hair starts to form
Tanner Stage 3
~age 12yo
Acne first appears; armpit hair forms; height increases at its fastest rate (peak height velocity), changes in fat distribution
Tanner Stage 4
~age 13yo
First period arrives
breasts continue to fill out, pubic hair more coarse
Tanner Stage 5
~age 15yo
final stage
breasts reach adult size and shape (though may continue to change through age 18yo)
periods become more regular
may be at adult height 1-2 years after first period
In a woman taking a combined oral contraceptive, the reduction in free androgens can yield an improvement in:
acne vulgaris
Free androgens, a precursor of testosterone, are linked to acne vulgaris. Combined oral contraceptives decrease free androgens, and consequently can improve acne vulgaris. While hormonal contraception can improve cycle control, it is not due to the androgen suppression but due to the consistent estrogen and progesterone administration. Similarly, breast tenderness is linked to estrogen fluctuations.
A 22-year-old woman presents for hepatitis screening. She is without symptoms but needs the testing for a job in the food service industry. Laboratory results are as follows: Anti-HCV with HCV RNA =positive. HBsAg=positive. Anti-HAV=negative. You advise the patient that she has….
chronic hepatitis B and C
is not immune to hepatitis A and recommend vaccination
This patient is seropositive for anti-HCV with HCV RNA present and, therefore, has an active hepatitis C infection. She is also positive for the hepatitis B surface antigen (HBsAg positive) and, therefore, has hepatitis B. However, she is seronegative for the antibody to the hepatitis A virus (anti-HAV negative) and, therefore, is susceptible to hepatitis A. It is appropriate to offer this patient vaccination against hepatitis A.
A 27-year-old woman presents for care. She reports a 3-day history of intense vaginal itch, burning with urination, and white, clumping discharge. She denies a foul odor but says it does smell a little musty. What history finding supports your diagnosis?
recent antibiotic use
The symptoms described are classic signs of a vaginal candidiasis (i.e., yeast infection), a fungal infection characterized by “spaghetti and meatball” pseudohyphae on microscopic examination. Antimicrobial use is a risk factor for yeast infections as the antimicrobial disrupts the normal bacterial flora of the genitourinary tract, thus allowing overgrowth by colonizing organism (e.g., Candida albicans). Vaginal candidiasis can develop during or following systemic antimicrobial therapy.
A 29-year-old well woman of Mediterranean ancestry presents for her first healthcare visit in many years. She relocated to North America from Italy after marrying a member of the US Armed Forces. A routine CBC reveals the following results:
–Hgb=9.6 g/dL (12–14 g/dL) (96 g/L [120–140 g/L])
–Hct=30% (36–42%) (.30 proportion [.36–.42 proportion])
–MCV=66 fL (80–96 fL)
–RDW=12% (<15%) (.12 proportion) (
beta thalassemia minor
- LOW Hgb
- LOW Hct
- LOW Mcv
- normal RDW
- normal RBCs
** very closely resembles iron-deficiency anemia, but you would expect elevated RDW in IDA
The mean cell volume (MCV) of 66 fL indicates microcytic anemia (normal MCV=80–96 fL). Iron deficiency anemia and thalassemia are the two most common microcytic anemias encountered in primary care and represent the leading differential diagnoses. Iron deficiency is most commonly a consequence of slow, steady blood loss and resulting depletion of iron, whereas thalassemia is a genetic disorder and not related to iron or any micronutrient deficiency. The normal red blood cell distribution width (RDW) indicates a stable anemia of long duration. Mediterranean ancestry is a risk factor for thalassemia, and the fact that the patient is a 29-year-old well woman suggests that this is a thalassemia minor form, with no impact on health. Consideration should be given to providing genetic counseling prior to pregnancy.
A 36-year-old woman presents with a 12-h history of anorexia, nausea, and right lower quadrant abdominal pain. A white blood cell count with differential demonstrates: –Total WBC=16,500 cells/mm³ –Neutrophils=66% –Bands=8% –Lymphocytes=22%
You suspect…..
appendicitis
This constellation of clinical symptoms is highly suggestive of appendicitis. The obturator and psoas signs are both consistent with pain during peritoneal stretch in the region of the appendix and are closely associated with appendicitis; the coincident abdominal pain, anorexia, and nausea strengthen the diagnosis. Consequently, the white blood cell (WBC) count will likely demonstrate an increase characterized by elevated neutrophils and bands; this pattern is commonly referred to as the “left shift”.
A 37-year-old woman presents with a 2-day history of right flank pain, fever, and vomiting. Physical examination is significant for costovertebral angle tenderness. A urinalysis is likely to reveal:
WBC casts
The symptoms presented by this woman suggest pyelonephritis, which is a serious bacterial infection of the renal parenchyma. The large number of white blood cells (WBCs) that migrate to the site of infection result in the accumulation of WBC casts in formed urine. Among the choices, the presence of WBC casts is the most specific indicator of an infectious condition.
A 41-year-old woman was recently diagnosed with systemic lupus erythematous. She complains of feeling generally fatigued and sometimes experiences palpitations. Her hemogram results are as follows: –Hgb=9.7 g/dL (97 g/L) –Hct=28% (0.28 proportion) –MCV=86 fL –RDW=12.5% (0.125 proportion) –Reticulocytes=0.9% (0.009 proportion)
These findings are most consistent with:
anemia of chronic disease
- Hgb LOW
- Hct LOW
- normal MCV
- normal RDW
- reticulocytes ???
(recticulocytes are low per the answer from Fitzgerald, normal per UpToDate)
The normal mean cell volume (MCV) indicates that both hemoglobin synthesis and red blood cell formation are unimpaired. The leading differentials for normocytic (MCV=80– 96 fL) anemia are anemia of chronic disease (ACD) and acute blood loss. The decreased reticulocyte count is a mechanism of ACD that in part results from increased differentiation of stem cells to white blood cells, with a resultant decrease in red blood cell production.
A 45-year-old woman complains of bilateral, intermittent itchy eyes, often accompanied by a rope-like discharge. The nurse practitioner expects that the history will include a patient report of:
seasonal allergies
Allergic conjunctivitis is characterized by itchiness, as most allergic reactions are. Unlike other forms of conjunctivitis, allergic conjunctivitis typically presents as bilateral. The rope-like discharge also supports a diagnosis of allergic conjunctivitis, in contrast to the watery discharge of viral conjunctivitis and purulent discharge of bacterial conjunctivitis. Corneal injury will be described as painful, not itchy. Sexually transmitted infection, such as gonorrhea or chlamydia, will likewise not itch, but will produce an irritation characterized by more infectious symptoms. Finally, decreased visual acuity suggests a more serious problem like uveal inflammation, intraocular pressure elevations, or retinal disease.
A 47-year-old woman presents for evaluation of erythematous, papular lesions on her forehead and chin. What is the most likely diagnosis?
acne rosacea
Acne vulgaris and acne rosacea are characterized by similar morphologies and distributions and both frequently are found on the forehead and chin. Tinea facialis does occur on the face but is characterized by the discrete annular lesions of tinea infection. Atopic dermatitis (eczema) is more common in children, though it can persist into adulthood, and is characterized by red- to brownish-grey patches most commonly on the hands, feet, ankles, wrists, neck, upper chest, and inside the bend of elbows and knees. In infants, the face and scalp can be affected.
A 52-year-old woman presents to your office as a new patient. She reports a long history of high blood pressure and admits that she does not regularly take her medication. What would be anticipated funduscopic findings?
- arteriolar narrowing
- AV nicking
- arteriosclerosis with moderate vascular wall changes (copper wiring)
- more severe vascular wall hyperplasia with thickening (silver wiring)
A long history of chronic poorly controlled hypertension can result in various ophthalmic changes, including permanent arterial narrowing, arteriovenous nicking, and arteriosclerosis with moderate vascular wall changes (copper wiring) to more severe vascular wall hyperplasia with thickening (silver wiring).
An increased cup:disc ratio is a sign of _____ caused by ________
sign of glaucoma
caused by elevated intraocular pressure
Major risks factors for macular degeneration include….
- age
- family history
- cigarette smoking
Macular degeneration is typically age-related and the leading cause of vision loss in those 55 years and older. A family history of the disease and cigarette smoking are implicated as risk factors for macular degeneration.
Leading cause of vision loss in those 55yo and older
macular degeneration
A 54-year-old woman presents for evaluation of a “cold sore” on her tongue. She has never had one in the past. She denies any pain, drainage, foul taste, or any other symptoms—“just have this sore that has been there for a while.” The history is significant for a 62 pack-year smoking history, currently smoking 1 PPD. Physical examination reveals an ulcerated lesion with firm, palpable, indurated margins. The most likely diagnosis is:
squamous cell carcinoma
Given this patient’s long history of cigarette smoking and the lesion’s characteristics, squamous cell carcinoma (SCC) should be suspected. More than 95% of patients with oral SSC smoke tobacco, drink alcohol, or both; this disease is often associated with human papilloma virus 16 infection. These lesions are typically asymptomatic initially and are often indurated and firm with a rolled border. Pain, dysarthria, and dysphagia can result as the lesions increase in size.
What is aphthous stomatitis
Aphthous stomatitis consists of shallow, painful ulcers that typically last 7–10 days.
A condition of benign, noncontagious, painful ulcers of the oral mucosa. Typically occur sporadically but can be triggered by viral infections and local trauma. Recurrent aphthous ulcers may be a sign of an underlying condition (e.g., Behçet disease, Crohn disease, celiac disease, vitamin B12 deficiency).
Most important risk factors for oral squamous cell carcinoma (3)
- smoking tobacco
- alcohol
- HPV 16
A physiologic (or “innocent”) murmur, which is by definition not associated with cardiac pathology, is characterized by several features, but one of the most definitive is that it typically …..
typically becomes softer when the patient stands.
The increased intracardiac volume that occurs when in the supine position exaggerates the murmur. When the patient stands, there is less volume in the heart chambers and the murmur decreases in intensity. This is directly opposite to the pathologic murmur of hypertrophic cardiomyopathy, in which the murmur becomes louder when the patient stands as a consequence of less fluid displacing the hypertrophic cardiac walls.
What is Grave’s Disease
Graves’ disease is an autoimmune disorder characterized by the pathologic production of thyroid stimulating immunoglobulins (TSI) that stimulate the thyroid gland and lead to elevated thyroxine levels. The elevated thyroxine levels suppress pituitary production of thyroid stimulating hormone (TSH). As a result, TSH levels will become very low, often undetectable. According to the American Thyroid Association (ATA), the TSH level is the most sensitive indicator of thyroid function.
According to the American Thyroid Association (ATA), the _____ level is the most sensitive indicator of thyroid function.
TSH
Migraines with aura represent what category on the Medical Eligibility Criteria for COCs
Category 4 (contraindicated)
The Centers for Disease Control and Prevention (CDC) created the U.S. Medical Eligibility Criteria for Contraceptive Use to offer recommendations for the use of specific contraceptive methods by women who have certain characteristics or medical conditions. Migraine with aura is a Category 4 circumstance (use represents unacceptable risk). Adequately-controlled hypertension is a Category 3 condition (risk usually outweighs the advantages), while smoking is a Category 2 circumstance for those <35 years of age, and a Category 3 circumstance for those =35 years (for those who smoke <15 cigarettes per day).
Adequately-controlled HTN represents what category on the Medical Eligibility Criteria for COCs

Category 4 (contraindication)
Actinic keratoses can be described as:
Actinic keratosis is most often described as a rough or sandpaper-textured pink, tan, or flesh-colored lesion on a sun-exposed region of the body
Actinic keratosis can be a precursor to:
squamous cell carcinoma
Actinic keratosis (AK) is considered a precancerous lesion given the possibility that it can progress to squamous cell carcinoma (SCC). AK does not progress to basal cell carcinoma or malignant melanoma. Approximately 1 AK lesion in 100 progress to SCC.
Activities are those that truly prevent disease, illness, or health deviation are referred to as _____ prevention

Category 4 (contraindicated)
The Centers for Disease Control and Prevention (CDC) created the U.S. Medical Eligibility Criteria for Contraceptive Use to offer recommendations for the use of specific contraceptive methods by women who have certain characteristics or medical conditions. The presence of hepatic adenoma is a Category 4 circumstance (use represents unacceptable risk). Age <40 years is Category 1 (no restriction on use) while age ≥40 years is Category 2 (advantages outweigh risks of use). Smoking by women <35 years old is a Category 2 circumstance.
Age <40yo represents what category on the Medical Eligibility Criteria for COCs

Category 2 (benefits usually outweigh the risks)
(3) factors implicated in acne vulgaris exacerbation
Sebaceous oil production, high levels of androgens, and frequent touching of the face have all been implicated in acne vulgaris exacerbation.
In advising a woman with menstruation-related migraine and combined oral contraceptive use, the nurse practitioner considers that:
uninterrupted use (continuous cycling) can minimize headache frequency and severity
In women with menstruation-related migraines on hormonal contraception, it is the fluctuation in hormone levels that is most closely linked to etiology of migraine. Uninterrupted use, and subsequently hormone levels, can help minimize headache frequency and severity. Estrogen can exacerbate headache, and high doses should be avoided.
Laboratory assessment of a patient with Hashimoto’s thyroiditis typically includes the presence of:
antithyroid peroxidase antibodies (anti-TPO antibodies)
Hashimoto’s thyroiditis is a condition characterized by the pathologic production of antithyroid peroxidase (anti-TPO) antibodies that block thyroid stimulating hormone (TSH) receptors on the thyroid gland. The gland does not function normally, and the result is hyperfunction of the pituitary and an elevated TSH.
Is it okay to continue breastfeeding when diagnosed with mastitis, or should the patient stop breast feeding or pump and dump?
ok to keep breastfeeding!
An engorged breast can actually contribute to mastitis, so the breast should be emptied completely. It is safe for the baby to nurse when the mother has mastitis, and so normal breastfeeding patterns should not be interrupted. If the mother is uncomfortable, she can be encouraged to begin with the unaffected breast and then switch to the affected breast.
Prophylactic treatment options for migraine include (3)
propanolol, timolol, topiramate
A variety of prophylactic therapies are used in patients with migraine headache with varying degrees of success, but topiramate and noncardioselective beta-adrenergic antagonists (e.g., propranolol) are generally regarded as among the most effective. Verapamil is no longer considered an effective option for migraine control. Ergotamine and sumatriptan are used for the management of acute migraine, but not for prevention. When prescribing topiramate, its teratogenic potential should be kept in mind.
(3) most common causative agents for bacterial infections of the HEENT
- streptococcus pneumoniae
- haemophilus influenzae
- M. catarrhalis
The most common organism implicated in bacterial infection of the head and neck, including acute bacterial rhinosinusitis (ABRS), acute otitis media (AOM), and bacterial pharyngitis, is S. pneumoniae. The second most common organism is H. influenzae while M. catarrhalis is a distant third.

Most common benign neoplasm of the cervix in folks between 30-50yo is….
cervical polyp
Cervical polyps occur in about 2–5% of women and most often affect women over the age of 20 years who have had children. They can cause irregular menstrual bleeding but often are asymptomatic. The Bartholin’s glands are not located on the cervix but on each side of the vaginal opening and secrete fluid that helps to lubricate the vagina. The openings of these glands can become obstructed, leading to the formation of a cyst. Cervical myomas are less common and usually coexist with uterine myomas (fibroids).
Molloscum contagiosum can be treated with….
trichloroacetic acid (TCA) or cryotherapy (liquid nitrogen)
Molluscum contagiosum is a relatively common viral infection of the skin that results in round, firm, painless bumps ranging in size from a pinhead to a pencil eraser. If the bumps are scratched or injured, the infection can spread to the surrounding skin. Though lesions typically resolve over time without treatment, removal is recommended given the highly contagious nature of the infection. Effective treatments include blistering agents (e.g., trichloroacetic acid) or cryotherapy (e.g., liquid nitrogen). Azithromycin, erythromycin and benzoyl peroxide are not effective against viral infections.

Greatest risk of infection with placement of an IUD occurs when?
within 20 days of insertion
Infection related to IUD use is usually the result of insertion where contamination of the uterine cavity with organisms from the vaginal flora occurs at the time of insertion. However, the risk of infection is minimal (~1%) and is limited to the first 20 days after insertion. Infections that occur beyond 20 days of insertion are likely to be sexually transmitted. Timing of insertion has no impact on infection risk, and antimicrobial prophylaxis has been shown to provide no benefit.
Optimal pregnancy interval
> 18-24 months
less than 5 years
Some risk factors for preterm birth
- prior preterm birth
- multiple gestation
- polyhydramnios
- uterine anomalies
- incompetent cervix

- uteroplacental insufficiency, smoking cigarettes, etc…..
At what point in the pregnancy does the CDC recommend screening for group B Streptococcus (GBS)?
35-37 weeks
Neonatal infection with group B Streptococcus (GBS) is a leading cause of newborn morbidity and mortality. Maternal lower genitourinary tract colonization with GBS is a major risk factor for early-onset disease, usually in the first week of life. The transmission of the organism from mother to fetus usually occurs after the onset of labor or membrane rupture. As a result, GBS screening should be performed in all women at 35 to 37 weeks of pregnancy, including women who are to undergo cesarean birth because the organism can cause infection across intact membranes.
Do you still need to screen for GBS in someone planning an elective cesarean?
Yes, in case they go into preterm labor AND because the organism can cause infection across intact membranes.
What change is a result of pubertal changes and helps defend the vagina from infection?
During puberty, the vaginal pH becomes more acidic, ranging from 3.8– 4.2 in healthy women of reproductive age, which inhibits growth of bacteria (though Candida species are viable in pH <4.5). During this time, estrogen production increases to induce the development of secondary sex characteristics. Physiologic leukorrhea is an anticipated puberty finding.
Normal vaginal pH, after puberty until menopause
3.8-4.2 (<4.5)
A woman with a past history of carrying a pregnancy where the fetus had a neural tube defect should be advised to…..
take 4mg (400mcg) folic acid daily for 3 months prior to attempting next pregnancy
Folic acid deficiency is a teratogenic state, leading to an increased risk of a neural tube defect (NTD) and other defects in the developing pregnancy. Correcting folic acid deficiency before pregnancy by increased dietary and supplement intake dramatically reduces the risk of defects, and continuing this increased intake during pregnancy minimizes the mother’s risk of developing folate deficiency anemia. As a result, if a woman has carried a pregnancy with an NTD, or there is a family history of NTD, recommended folic acid intake is 4 mg per day for 3 months before attempting a subsequent pregnancy.
Within the first hours after a normal spontaneous vaginal delivery, a woman can exhibit an elevated WBC count (>20,000 mm³) as well as slight temperature elevation. This is a typical response in the immediate postpartum woman due to….
dehydration
During the postpartum period, women can exhibit a slight temperature elevation due to dehydration following delivery. It is also normal for the WBC count to increase markedly during labor, rising up to 20,000 to 30,000 mm³ in the first 24 hours postpartum. The WBC count will return to normal within 1 week. As a result, the woman should be encouraged to drink adequate amounts of fluids and to rest. Additional diagnostic tests are not warranted.
WBC count is expected to return to normal levels within _____ post-partum
1 week
WBC count can physiologically increase to as high as _______ during labor and in the first 24 hrs postpartum
20,000-30,000 mm3
<21 days postpartum represents what category on the Medical Eligibility Criteria for COCs
category 4 (contraindicated)
Initiation of contraception during the postpartum period is important to prevent unintended pregnancy and short birth intervals. However, the use of combined oral contraception (COC) during the first 21 days after delivery is not recommended due to a high risk of venous thromboembolism during this period (US MEC Category 4). Use of COC during 21 to 42 days postpartum is given Category 2/3 (depending on presence of other risk factors for VTE), while no restrictions are placed on COC use >42 days postpartum (Category 1). Progestin-only pills (POP) are generally regarded as the better choice in breastfeeding mothers as they do not interfere with the milk supply in the way that estrogen-containing contraceptives can. POPs can be used safely during breastfeeding in the immediate postpartum woman (Category 2). DMPA injection and etonogestrel implants are also safer alternatives to COC in immediate postpartum breastfeeding women (Category 2).
> 42 days postpartum represents what category on the Medical Eligibility Criteria for COCs
category 1 (no restriction), although progestin-only pills are generally regarded as the better choice for folks who are breastfeeding as they are not thought to interfere with milk supply in the same way that estrogen does
