Questions 1–100: Practice Questions, Answers,
and Rationales
Section 1: Endocrine Assessment and
Hypothyroidism
Question 1
A patient reports fatigue, cold intolerance, constipation, and unexplained weight gain.
Which condition is most consistent with these findings?
A. Hyperthyroidism B. Hypothyroidism C. Diabetes insipidus D. Cushing syndrome
Rationale: Hypothyroidism results from insufficient thyroid hormone activity and can
slow metabolic processes, producing fatigue, cold intolerance, constipation, and
weight gain. Hyperthyroidism generally causes increased metabolism, while diabetes
insipidus primarily affects water balance. Cushing syndrome is associated with excess
cortisol.
Question 2
Which laboratory pattern is most consistent with primary hypothyroidism?
,2
A. Low TSH and elevated free T4 B. Normal TSH and elevated free T4 C. Elevated
TSH and low free T4 D. Low TSH and low free T4 in every case
Rationale: In primary hypothyroidism, the thyroid gland produces insufficient
hormone. The pituitary responds by increasing thyroid-stimulating hormone (TSH),
so TSH rises while free thyroxine (T4) falls. Low TSH with low free T4 may instead
suggest central hypothyroidism.
Question 3
A patient newly diagnosed with hypothyroidism asks why levothyroxine has been
prescribed. What is the best explanation?
A. It blocks insulin secretion B. It replaces deficient thyroid hormone C. It suppresses
adrenal cortisol production D. It directly treats bacterial skin infections
Rationale: Levothyroxine is synthetic T4 used to replace deficient thyroid hormone. It
does not treat diabetes, suppress cortisol, or act as an antibiotic.
Question 4
Which instruction is most appropriate for a patient taking levothyroxine?
A. Take it only when symptoms occur B. Take it with an iron supplement to improve
absorption C. Take it consistently on an empty stomach as directed D. Stop it once
fatigue improves
Rationale: Levothyroxine is generally taken consistently on an empty stomach, often
30–60 minutes before breakfast, following the prescriber's directions. Iron and
calcium can reduce absorption and are commonly separated from levothyroxine by
several hours. Treatment should not be stopped simply because symptoms improve.
Question 5
A patient taking levothyroxine develops palpitations, tremor, and heat intolerance.
What should the nurse consider?
A. The dose is definitely too low B. Thyroid hormone over-replacement may be
occurring C. These symptoms prove that hypothyroidism is worsening D. The patient
has developed dermatitis
Rationale: Palpitations, tremor, and heat intolerance can indicate excessive thyroid
hormone replacement. The patient should be assessed and referred to the prescriber
for appropriate evaluation, including thyroid function testing. Symptoms alone do not
establish the cause.
Question 6
, 3
Which test is commonly used to monitor treatment for uncomplicated primary
hypothyroidism?
A. Serum amylase B. Hemoglobin alone C. Thyroid-stimulating hormone (TSH) D.
Urine ketones alone
Rationale: TSH is commonly used to monitor levothyroxine treatment in primary
hypothyroidism. Free T4 and clinical status may also be assessed. Amylase,
hemoglobin, and urine ketones answer different clinical questions.
Question 7
A patient has elevated TSH and normal free T4, with few symptoms. Which condition
may this pattern indicate?
A. Thyroid storm B. Subclinical hypothyroidism C. Diabetic ketoacidosis D. Primary
adrenal crisis
Rationale: Subclinical hypothyroidism is characterized by an elevated TSH with free
T4 within the reference range. Management depends on the degree and persistence of
TSH elevation, symptoms, pregnancy status, antibody results, and other clinical
factors.
Question 8
Which finding is particularly concerning in a patient with severe, untreated
hypothyroidism?
A. Mild seasonal sneezing B. Temporary itching after using soap C. Altered mental
status with hypothermia and bradycardia D. Increased appetite with sweating
Rationale: Altered mental status, hypothermia, and bradycardia may indicate severe
decompensated hypothyroidism, sometimes termed myxedema coma. This is a
medical emergency. Increased appetite and sweating are more suggestive of
hypermetabolic states.
Question 9
Which statement about Hashimoto thyroiditis is correct?
A. It is always caused by iodine poisoning B. It is an autoimmune condition that can
cause hypothyroidism C. It is a bacterial infection of the thyroid D. It is a disorder of
insulin-producing pancreatic cells
Rationale: Hashimoto thyroiditis is an autoimmune disorder in which immune-
mediated thyroid damage can reduce hormone production. It is not a bacterial
infection or a primary pancreatic disorder.
