A nurse practitioner is evaluating a patient with suspected hypothyroidism.
Which of the following laboratory findings is most consistent with primary
hypothyroidism?
a. Decreased TSH and decreased free T4
b. Increased TSH and decreased free T4
c. Increased TSH and increased free T4
d. Decreased TSH and increased free T4
Correct Answer: b. Increased TSH and decreased free T4
Expert Rationale
Primary hypothyroidism occurs when the thyroid gland fails to produce
adequate thyroid hormones. As a result, free T4 levels decrease while TSH
increases due to pituitary compensation. This pattern confirms primary
thyroid gland dysfunction. Option a (Decreased TSH and decreased free T4)
suggests central hypothyroidism (pituitary or hypothalamic). Option c
(Increased TSH and increased free T4) is not a typical pattern. Option d
(Decreased TSH and increased free T4) indicates hyperthyroidism. The NP
should initiate levothyroxine replacement therapy and monitor TSH levels.

A nurse practitioner is prescribing medication for a patient newly
diagnosed with type 2 diabetes. Which medication is considered first-line
therapy if no contraindications exist?
a. Glipizide
b. Metformin
,c. Insulin glargine
d. Pioglitazone
Correct Answer: b. Metformin
Expert Rationale
Metformin is the recommended first-line pharmacologic treatment for type 2
diabetes because it decreases hepatic glucose production, improves insulin
sensitivity, and does not typically cause hypoglycemia or weight gain. Option
a (Glipizide) is a sulfonylurea that can cause hypoglycemia and weight gain.
Option c (Insulin glargine) is not first-line for newly diagnosed type 2
diabetes. Option d (Pioglitazone) is a thiazolidinedione with fluid retention
risks. The NP should start metformin at a low dose and titrate to minimize
gastrointestinal side effects.

A nurse practitioner is evaluating a patient with chest pain suspected to be
myocardial infarction. Which biomarker is most specific for myocardial
injury?
a. Creatine kinase (CK)
b. CK-MB
c. Troponin I
d. Myoglobin
Correct Answer: c. Troponin I
Expert Rationale
Cardiac troponins (troponin I and T) are the most sensitive and specific
markers for myocardial injury. They begin rising within 3–6 hours after
myocardial infarction and remain elevated for several days. Option a (CK) and
Option b (CK-MB) are less specific and may be elevated in skeletal muscle
injury. Option d (Myoglobin) is early but non-specific. The NP should obtain
troponin levels in all patients with suspected acute coronary syndrome.

,A nurse practitioner is counseling a patient about hypertension
management. Which lifestyle modification has the greatest effect on
lowering blood pressure?
a. Reducing sodium intake
b. Weight loss
c. Limiting alcohol intake
d. Increasing potassium intake
Correct Answer: b. Weight loss
Expert Rationale
Weight reduction has one of the greatest effects on blood pressure
reduction. Even modest weight loss (5–10% of body weight) can significantly
lower blood pressure and reduce cardiovascular risk. Option a (Reducing
sodium intake) is effective but less impactful than weight loss. Option c
(Limiting alcohol) and Option d (Increasing potassium) are also beneficial but
not as potent. The NP should prioritize weight loss counseling for overweight
hypertensive patients.

A nurse practitioner is prescribing an ACE inhibitor for hypertension. Which
adverse effect should the patient be instructed to report immediately?
a. Dry cough
b. Dizziness
c. Angioedema
d. Headache
Correct Answer: c. Angioedema
Expert Rationale
Angioedema is a rare but life-threatening adverse effect of ACE inhibitors
characterized by swelling of the face, lips, tongue, or airway, which can lead
to airway obstruction. Immediate medical attention is required. Option a
(Dry cough) is common but not emergent. Option b (Dizziness) and Option d
(Headache) are common and generally not life-threatening. The NP should
instruct the patient to seek emergency care if any swelling occurs.

A nurse practitioner is assessing a patient with suspected appendicitis.
Which finding is most indicative of this condition?
a. Pain in the left lower quadrant
b. Rebound tenderness at McBurney's point
c. Pain relieved by movement
d. Hyperactive bowel sounds
Correct Answer: b. Rebound tenderness at McBurney's point
Expert Rationale
McBurney's point tenderness in the right lower quadrant with rebound
tenderness is a classic sign of appendicitis caused by inflammation of the
appendix. Option a (Left lower quadrant pain) suggests diverticulitis. Option
c (Pain relieved by movement) is not typical; movement worsens pain.
Option d (Hyperactive bowel sounds) is not specific. The NP should consider
immediate surgical consultation if appendicitis is suspected.

A nurse practitioner is treating a patient with community-acquired
pneumonia. Which pathogen is the most common cause in adults?
a. Mycoplasma pneumoniae
b. Streptococcus pneumoniae
c. Haemophilus influenzae
d. Staphylococcus aureus
Correct Answer: b. Streptococcus pneumoniae
Expert Rationale
Streptococcus pneumoniae remains the most common cause of community-
acquired pneumonia in adults and is a key organism targeted by empiric
antibiotic therapy. Option a (Mycoplasma) is more common in younger
adults. Option c (Haemophilus) and Option d (Staphylococcus) are less
