Question 1
A patient presents with thinning of the outer one-third of the eyebrows and non-pitting edema of the lower
extremities. Which endocrine disorder is most likely responsible for these symptoms?
A. Hyperthyroidism
B. Hypothyroidism
C. Thyroid carcinoma
D. Hyperparathyroidism
Correct Answer
B
Rationale:
Hypothyroidism commonly presents with myxedema (non-pitting edema) and loss of the outer third of the eyebrows due to reduced
thyroid hormone levels affecting hair growth and tissue metabolism. Hyperthyroidism causes hair thinning but not localized eyebrow
loss, thyroid carcinoma is typically asymptomatic early on, and hyperparathyroidism affects calcium levels without these specific
skin/hair changes. Hypothyroidism commonly presents with myxedema (non-pitting edema) and loss of the outer third of the
eyebrows due to reduced thyroid hormone levels affecting hair growth and tissue metabolism. Hyperthyroidism causes hair thinning

,Question 2
In a woman with type 1 diabetes mellitus who becomes pregnant, what typically happens to her insulin
requirements during the first trimester?
A. They decrease significantly
B. They remain unchanged
C. They increase due to hormonal changes
D. They fluctuate unpredictably
Correct Answer
A
Rationale:
In early pregnancy, insulin requirements often decrease due to increased progesterone and estrogen levels, which enhance insulin
sensitivity. Later trimesters see increases. This contrasts with the general trend of increasing needs overall in pregnancy for type 1 DM.

Question 3
What is the primary purpose of periodic examinations for patients with known diabetes mellitus?
A. To prescribe new antidiabetic medications
B. To evaluate blood glucose control and assess for end-organ damage
C. To monitor weight loss progress only
D. To adjust dietary plans exclusively
Correct Answer
B
Rationale:
Periodic exams in DM aim to assess glycemic control (e.g., A1C) and screen for complications like retinopathy, nephropathy, and
neuropathy (end-organ damage), as per ADA guidelines. Other options are secondary or not primary focuses. Periodic exams in DM

Question 4
A patient with suspected hypothyroidism is evaluated. What laboratory findings would the NP expect?
A. Low TSH and high free T4
B. High TSH and low free T4
C. High TSH and high free T4
D. Low TSH and low free T4
Correct Answer
B
Rationale:
Primary hypothyroidism features elevated TSH due to pituitary compensation for low thyroid hormone (low free T4) production. High
TSH with high T4 suggests resistance, low TSH with high T4 indicates hyperthyroidism, and low TSH with low T4 suggests secondary
hypothyroidism. Primary hypothyroidism features elevated TSH due to pituitary compensation for low thyroid hormone (low free T4)
production. High TSH with high T4 suggests resistance, low TSH with high T4 indicates hyperthyroidism, and low TSH with low T4
suggests secondary hypothyroidism.

, Question 5
Which symptom is most characteristic of hyperthyroidism?
A. Weight gain and fatigue
B. Heat intolerance and tachycardia
C. Cold intolerance and bradycardia
D. Constipation and dry skin
Correct Answer
B
Rationale:
Hyperthyroidism increases metabolic rate, leading to heat intolerance and sympathetic overactivity (tachycardia). Hypothyroidism
causes the opposite (cold intolerance, bradycardia), while weight gain and dry skin are hypothyroid features. Hyperthyroidism

Question 6
For a patient newly diagnosed with type 2 diabetes, what is the target A1C level according to ADA guidelines?
A. Less than 6.0%
B. Less than 7.0%
C. Less than 8.0%
D. Less than 9.0%
Correct Answer
B
Rationale:
ADA recommends an A1C <7% for most non-pregnant adults with diabetes to reduce microvascular complications, individualized
based on patient factors. Higher targets apply to those with comorbidities. ADA recommends an A1C <7% for most non-pregnant

Question 7
In hyperparathyroidism, what is the most common cause of hypercalcemia in outpatients?
A. Malignancy
B. Primary hyperparathyroidism
C. Vitamin D excess
D. Thiazide diuretic use
Correct Answer
B
Rationale:
Primary hyperparathyroidism (adenoma) is the leading outpatient cause of hypercalcemia. Malignancy is more common in
inpatients, while vitamin D and thiazides are less frequent. Primary hyperparathyroidism (adenoma) is the leading outpatient cause
