B. metformin
C. repaglinide
D. pioglitazone
B. Metformin
B. Lactate accumulation.
B.
C. Linagliptin
C. Pioglitazone. This may exacerbate CHF because of fluid retention.
B. decrease storage of triglycerides.
A. Methimazole
C.
D. PTU
C. Glucocorticoids
Metformin should be discontinued and switched to a different medication for which reason?
A. GFR below 30 mL/min
B. Diarrhea
C. Abdominal pain
D. Radiological study with contrast
A. Metformin is contraindicated with GFR below 30 mL/min.
The APN is seeing a patient with a history of diabetes and hypothyroidism. The patient recently discovered that she was 8 weeks pregnant. The APN should expect to take which action?
A. Increase thyroid replacement by 25%
B. Decrease thyroid replacement by 25%
C. Decrease beta blocker by 50%
D. Increase beta blocker by 50%
A. Metabolic requirements are increased during pregnancy. Increasing hormone replacement by 25% results in adequate coverage during pregnancy.
What are the goals of treatment for hypothyroidism?
A. Increase in TSH levels
B. Decrease in T4 levels
C. Increase in Free thyroxine index (FT4I)
D. Decrease in Free T3 (FT3)
C. Normalization of FT4I levels within a therapeutic range are desired. As hypothyroidism leads to decreased levels, this would be a goal of treatment.
The APN is providing instruction to an adult patient who has been prescribed thyroid hormone replacement therapy. Which patient finding would warrant additional instruction if observed by the APN?
A. Take medication if the pulse rate is recorded at 72 bpm
B. Take medication in the morning before eating breakfast
C. Patient states that if they miss a dose, they can take the medication at dinner time
D. Patient takes the same thyroid preparation medication each day
C. If a dose is missed, it may be taken that same day as soon as it is remembered, 4 hours after eating. As the patient states they are going to take the medication at dinner time, the APN should provide additional instruction that an empty stomach enhances absorption.
Which clinical situation would signify an inappropriate use of thyroid hormone therapy?
A. Increased TSH level with clinical symptoms
B. Patient complaints of chronic depression with normal TSH levels
C. Treatment of hypothyroidism in a patient having infertility issues
D. Treating hypothyroidism in a patient who is also being treated for depression
B. Use of thyroid supplementation for chronic depressive states without abnormal TSH is not supported by evidence.
Which of these is a microvascular complication of uncontrolled diabetes?
A. Proliferative retinopathy
B. Cardiovascular disease
C. Stroke
D. Peripheral vascular disease
A. Uncontrolled diabetes can result in microvascular and macrovascular complications. Microvascular involvement affects the eyes, heart, kidney, and nervous system.
Which type of therapy is recommended for a pregnant patient who also is found to be hyperthyroid during the first trimester?
A. Synthroid
B. Propylthiouracil
C. Methimazole
D. Insulin
B. Propylthiouracil is the preferred ATD during pregnancy because it is 80% to 90% protein bound and less likely to cross the placenta. Methimazole is teratogenic in the first trimester.
The APN is evaluating an adult female patient, age 35, who presents to the emergency department with flushed skin, complaints of heat intolerance, and agitation. Patient has noticed symptoms progressing over the past few weeks and denies any stress or precipitating factors. Baseline EKG reveals tachycardia with no other abnormalities. Which disease process should the APN suspect?
A. Hyperthyroidism
B. Congestive heart failure (CHF)
C. Panic attack
D. Menopause
A. Hyperthyroidism. Symptoms include palpitations, tremor, anxiety, possible weight loss, heat intolerance, and heightened sensitivity to sympathetic nervous system stimulation in hyperthyroidism.
Which concern should the APN evaluate for adult patients who are considering taking sitagliptin (Januvia) monotherapy?
A. History of congestive heart failure
B. GFR of 60 or higher
C. Nonpregnant
D. Prior cholecystectomy
A. Hx CHF. Heart failure continues to be a concern with the entire class of drugs.
Which of these is the drug of choice for treatment of hyperthyroidism in pregnancy?
A. Methimazole
B. Levothyroxine
C. Propylthiouracil (PTU)
D. Propranolol
C. Propylthiouracil is the drug of choice during pregnancy because it crosses the placenta in low concentrations.
The APN is preparing to prescribe medication to an adult patient who is overweight and newly diagnosed with type 2 diabetes and has not had effective change in blood glucose levels using lifestyle modifications. Which medication should the APN prescribe?
A. Metformin
B. Glipizide
C. Insulin therapy
D. Janumet (sitagliptin + metformin)
A. Metformin is indicated as monotherapy and in multidrug therapy for patients with type 2 DM who cannot achieve adequate BG control on the typical lifestyle modifications of healthy eating, increased activity, and weight loss.
The APN is assessing an adult patient who presents with complaints of irritability, recent weight loss and feeling hot. Which laboratory test should the APN order?
A. Oral Glucose Tolerance Test (OGTT)
B. Lipid panel
C. TSH and T4
D. Fasting Blood Sugar (FBS)
C. The APN should suspect that the patient has hyperthyroidism, therefore thyroid function tests should be ordered.
When do the symptoms of type 1 diabetes begin?
A. After 80% to 90% of beta cell loss
B. After 40% to 50% of beta cell loss
C. After 20% to 30% of beta cell loss
D. After 60% to 70% of beta cell loss
A. Before hyperglycemia occurs, 80% to 90% of the function of insulin-secreting beta cells of the pancreas must be lost.
Which screening test is used to assess for congenital hypothyroidism in newborns?
A. Hemoglobin A1c
B. APGAR
C. Capillary blood screening
D. Blood glucose
C. Capillary blood screening of all infants in the U.S. and Canada before discharge from the hospital or birthing center tests for this disorder.
The APN diagnoses the patient with diabetes after obtaining an HbA1c of 12% in the office. The fasting blood glucose today is 135. The patient complains of a history of polyphagia, polydipsia, and polyuria. Which medication would be most appropriate to start today?
A. Insulin lispro and insulin glargine
B. Metformin
C. Glipizide
D. Metformin and sitagliptin
A. Oral hypoglycemic agents have limited ability to reduce hyperglycemia; therefore, for patients who initially present with blood glucose levels above 300 mg/dL, HbA1c greater than 10%, or significant hyperglycemic symptoms, insulin therapy is strongly recommended to lower PG to less than 180 mg/dL before oral agents are begun.
A patient with type 2 diabetes mellitus (DM) has concerns about starting insulin because of his current occupation. He states that his food intake has increased in the past 2 months, which has resulted in elevated home blood sugars. After a review of the home blood glucose readings, the APN decides on a medication to improve pre- and postprandial blood glucose levels. The addition of which medication is most appropriate?
A. Dulaglutide
B. Sitagliptin
C. Pramlintide
D. Nateglinide
B. Dipeptidyl peptidase-4 (DPP-4) inhibitors have demonstrated efficacy in reducing pre- and postprandial blood glucose levels.
The APN should avoid prescribing which medication for a patient diagnosed with gestational diabetes?
A. Metformin
B. Insulin
C. Glyburide
D. Canagliflozin
D. Sodium-glucose cotransporter 2 (SGLT-2) inhibitors, such as canagliflozin, may affect renal development and maturation in utero. These medications should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Which food selection should be avoided in patients who have hyperthyroidism?
A. Carrots
B. Highly seasoned food
C. High protein snacks
D. Potatoes
B. Patient who have hyperthyroidism should avoid highly seasoned foods as it can lead to facial flushing and tachycardia.
