Mod 7 Butarro Ch 185-194 Flashcards
A patient has new-onset hypertension with a systolic blood pressure of 180 mm Hg. Which test will the provider order to diagnose this patient?
a. ACTH suppression testing
b. Adrenal antibody tests
c. Cortisol excretion studies
d. Fractionated metanephrine levels
d. Fractionated metanephrine levels
This patient may be experience signs of a pheochromocytoma adrenal tumor.
**hall mark symptoms is new sudden onset hypertension with systolic pressure >170 mm Hg.
diagnosed by a urine test that will show Fractionated metanephrine will be elevated when the diagnosis is confirmed.
Pheochromocyoma is one of the most common adrenal gland disorders treated by managing bp and surgical resection
other common adrenal disorders:
1. Addison Disease (primary adrenal insufficiency)
CAUSED BY: (autoimmune) destruction or injury of adrenal gland most common, pituitary tumors of TBIs, or high dose use of exogenous steroids
SX: hyperpigmentation and skin changes, dehydration, salt craving, weight loss, malaise, nauseam, abdominal pain, impaired memory
DX by: blood test show serum levels of ACTH High and serum cortisol levels low. may cause electrolyte problems AND adrenal antibody tests are performed as part of the evaluation for Addison’s disease.
TX: with steroids
- Cushing Disease:
CAUSED by suppression of the pituitary function that cased decrease in production of ACTH which then causes an over production of cortisol (tumor)
DX serum acth low and high levels of cortisol, urine
positive for cortisol >100mcg AND ACTH suppression testing and cortisol excretion studies are performed to diagnose an suppression testing
SX: moon face, buffalo hump, strai, depression, weight gain, purpura, mild hypertension, dec libido, increase glucose, amenorrhea without pregnanct
TX: fix underlying cause (like tumor)
A patient has rapid weight gain, amenorrhea without pregnancy, and mild hypertension. Once confirmatory tests are performed, what is a possible treatment for this patient?
a. Antihypertensive therapy
b. Mineralocorticoid replacement
c. Oral hydrocortisone
d. Pituitary tumor resection
d. Pituitary tumor resection
This patient has symptoms of Cushing’s syndrome. When indicated, pituitary tumor resection is performed as the first choice.
Antihypertensive therapy is initiated in patients with pheochromocytoma.
Mineralocorticoids and glucocorticoids are given to patients with Addison’s disease.
A patient has unexplained weight loss and the provider notes increased skin pigmentation on light-exposed skin folds along with darkened palmar creases. Which laboratory tests will the provider order? (Select all that apply.)
a. Serum ACTH
b. Serum cortisol
c. Serum electrolytes
d. TB skin testing
e. Urine cortisol
a. Serum ACTH
c. Serum electrolytes
d. TB skin testing
Addison Disease (primary adrenal insufficiency)
CAUSED BY: (autoimmune) destruction or injury of adrenal gland most common, pituitary tumors of TBIs, or high dose use of exogenous steroids
SX: hyperpigmentation and skin changes, dehydration, salt craving, weight loss, malaise, nauseam, abdominal pain, impaired memory
DX by: blood test show serum levels of ACTH High and serum cortisol levels low. may cause electrolyte problems (na and k AND adrenal antibody tests are performed as part of the evaluation for Addison’s disease.
TX: with steroids
This patient has symptoms of Addison’s disease. Serum ACTH will be elevated in patients with Addison’s disease. Hyponatremia and hyperkalemia may occur and are sometimes the initial finding.
TB skin testing is done to exclude tuberculosis typically symptoms are similar must r/o
Serum and urine cortisol levels are evaluated with Cushing’s syndrome is suspected.
An obese patient has recurrent urinary tract infections and reports feeling tired most of the time. What initial diagnostic test will the provider order in the clinic at this visit?
a. C-peptide level
b. Hemoglobin A1C
c. Random serum glucose
d. Thyroid studies
b. Hemoglobin A1C
HbA1C, along with fasting plasma glucose or a 2-hour plasma glucose during an oral glucose tolerance test (OGTT), is diagnostic of diabetes.
This patient is probably not fasting, so a glucose level will not be helpful.
C-peptide levels help to distinguish type 1 from type 2 diabetes and may be performed after a diagnosis of diabetes is made and if there is uncertainty about the cause.
Thyroid studies are helpful in evaluating comorbidity.
A patient diagnosed with type 2 diabetes mellitus becomes insulin dependent after a year of therapy with oral diabetes medications. When explaining this change in therapy, the provider will tell the patient
a. it is necessary because the patient cannot comply with the previous regimen.
b. that strict diet and exercise measures may be relaxed with insulin therapy.
c. the use of insulin therapy may be temporary.
d. this is because of the natural progression of the disease.
d. this is because of the natural progression of the disease.
Even after several years of therapy for type 2 DM well controlled with oral diabetic medications, diet, and exercise, the natural progression of the disease may require patients to become insulin dependent.
Patients must understand that this does not represent failure on their part.
Adding insulin may cause weight gain, so continuing lifestyle measures is essential. The addition of insulin is not temporary.
A patient diagnosed with diabetes has a blood pressure of 140/90 mm Hg and albuminuria. Which initial action by the primary care provider is indicated for management of this patient?
a. Consulting with a nephrologist
b. Limiting protein intake
c. Prescribing an antihypertensive medication
d. Referring to an ophthalmologist
a. Consulting with a nephrologist
Patients with diabetes who have elevated blood pressure and reduced renal function should be referred to a nephrologist. *hypertension and albuminuria is first sign of kidney damage must see nephrologist first who will probably start them on a ARB or ACE
Limiting protein intake and giving an antihypertensive medication may be recommended, but evaluation by a nephrologist is essential.
Ophthalmology referral will be made as well to assess concurrent ocular damage.
A patient recently diagnosed with type 1 diabetes mellitus is in clinic for a follow-up evaluation. The provider notes that the patient appears confused and irritable and is sweating and shaking. What intervention will the provider expect to perform once the point of care blood glucose level is known?
a. Dipstick urinalysis for ketones
b. Giving a rapid-acting carbohydrate
c. Injection of rapid-acting insulin
d. Performing a hemoglobin A1C
b. Giving a rapid-acting carbohydrate
This patient has signs of hypoglycemia, so a rapid-acting carbohydrate should be given once this is confirmed. Assessing for ketones is done if the patient is hyperglycemic, as is insulin administration. Hemoglobin A1C gives information about long-term and not immediate glucose control.
Type 1 dm more hypoglycemia more likely to happen as well as DKA Type 1 = insulin deficiency due to auto immune process taking insulin making cells in the pancreas
An obese adolescent female patient reports irregular periods and excessive acne. The provider notes an increased amount of hair on her upper back, shoulders, and upper abdomen. What will the provider do, based on these findings?
a. Consider treatment with oral contraceptive pills (OCPs)
b. Counsel her about diet, exercise, and weight loss
c. Recommend cosmetic laser hair removal
d. Refer to an endocrinologist for evaluation
d. Refer to an endocrinologist for evaluation
All patients with suspected hirsutism should be referred to a specialist to determine the cause.
OCPs, lifestyle changes, and cosmetic treatments may be part of the treatment, but the underlying causes must be determined first to ensure that a life-threatening condition is not present
A young adult woman is unable to conceive after trying to get pregnant for over 6 months. The woman reports having had irregular periods since the onset of menarche. The provider notes that the woman is overweight, has acanthosis nigricans, and an excess hair distribution. What does the provider suspect as the most likely primary cause of these symptoms?
a. Congenital adrenal hyperplasia
b. Cushing’s syndrome
c. Polycystic Ovary Syndrome (PCOS)
d. Type 2 diabetes
c. Polycystic Ovary Syndrome (PCOS)
PCOS is the most likely cause of oligo- or amenorrhea, so this is the most likely cause. The other conditions are possible, but less likely.
A woman who has hirsutism with acne, and oligomenorrhea will most likely be treated with which medication to control these symptoms?
a. Finasteride
b. Levonorgestrel
c. Norgestimate
d. Spironolactone
c. Norgestimate
Norgestimate is a progestin with low androgenic activity and is used to suppress testosterone and control symptoms. Finasteride, which decreases the peripheral conversion of testosterone to dihydrotestosterone (DHT), is not approved for this use. Levonorgestrel is an androgenic oral contraceptive pill (OCP) and should be avoided. Spironolactone is a second-line medication approved for this purpose.
A patient is in the emergency department with confusion and fatigue and a corrected serum calcium concentration is 10.8 mg/dL. What is the initial treatment for this patient prior to admission to the inpatient unit?
a. Administration of furosemide
b. Correction of potassium and magnesium levels
c. Parenteral salmon calcitonin
d. Rapid administration of intravenous normal saline
d. Rapid administration of intravenous normal saline
normal levels of CA should be 8.5 -10.5 anything >10.5 needs to be corrected or anything <8.5 needs to be corrected
this patient has ca >10.5 and treatment for hypercalcemia is maintaining fluid hydration status. that is the only way to get rid of excess ca
causes of hypercalcemia:
PTH dysfunction lead to increase levels which leads to increased bone reabsorption
secondary kidney disease CA is only excreted by urine or
sx: change in neuostatus, caridac problems, gastsro symptoms
Malignancy (tumor)= most common cause
Milk alkali syndrome: when a patient is not in renal failure hypercalcemia can be induced by high intake of milk
other caused high levels of Vitamin D or Lithium, thiazide diuretics
A patient experiences a carpal spasm when a blood pressure cuff is inflated. Which diagnostic testing will the provider consider evaluating to determine the cause of this finding?
a. Calcitriol level
b. C-reactive protein
c. Magnesium and vitamin D
d. Protein electrophoresis
c. Magnesium and vitamin D
Hypocalcemia may be asymptomatic but prolonged dec ca can cause neuromuscular excitatibility and numbness and tingling ness of extremities and can lead to seizures, coma,
as evidence by increased hyperreflexia of deep tendons
+ trouseau’s signs- carpel spasm occurring after occlusion of brachial artery with bp cuff for 3 minutes
+chvosteks sign- contraction of the facial muscle in response to tapping on facial nerve against bone of anterior ear.
Because hypomagnesemia and vitamin D deficiency may cause hypocalcemia, these should be evaluated to help determine a cause.
Calcitriol levels are used to assess hypercalcemia.
Protein electrophoresis is used in the evaluation of hypercalcemia.
A patient has low serum calcium associated with low serum albumin. What is the recommended treatment for this patient?
a. Calcium supplementation only
b. Correction of other serum electrolytes
c. Thiazide diuretics and sodium restriction
d. Vitamin D and calcium supplementation
b. Correction of other serum electrolytes
Patients with hypocalcemia associated with hypoalbuminemia do not require calcium replacement. Serum pH, potassium, magnesium, and phosphorus levels should be monitored and corrected if needed. Thiazide diuretics with sodium restriction may be used to lower urinary calcium excretion to allow lower dosing of calcium and vitamin D when these are given.
A patient has a serum potassium level of 3 mEq/L and a normal blood pressure. Which test should be performed initially to assist with the differential diagnosis?
a. Plasma aldosterone
b. Plasma renin activity
c. Serum bicarbonate
d. Serum magnesium
d. Serum magnesium
Hypomagnesemia often accompanies hypokalemia indicating the importance of also obtaining a serum magnesium level.
Sodium bicarbonate is occasionally used in the treatment of hyperkalemia and is most effective when hyperkalemia is a result of metabolic acidosis.
Plasma aldosterone and renin activity are assessed in patients with hypokalemia who are hypertensive.
A patient with normal renal function has a potassium level of 6.0 mEq/L. Which underlying cause is possible in this patient?
a. Adrenocortical deficiency
b. Alcoholism
c. Hypertension
d. Malabsorption syndrome
a. Adrenocortical deficiency
Hyperkalemia without underlying renal disorder may be caused by Addison’s disease, which is an adrenocortical deficiency. Alcoholism, hypertension, and malabsorption syndromes all contribute to hypokalemia.
