1. Which of the following would you expect in a patient with
Addison’s disease?
A. Increased blood pressure
B. Hyperkalemia
C. Weight gain
D. Increased appetite
Answer: B) Hyperkalemia
Rationale: Addison’s disease, a disorder of the adrenal glands,
leads to decreased cortisol and aldosterone production. This
results in fluid and sodium loss and potassium retention, causing
hyperkalemia.
2. A patient with hypothyroidism is most likely to have which of
the following symptoms?
A. Weight loss
B. Increased heart rate
C. Cold intolerance
D. Heat intolerance
Answer: C) Cold intolerance
Rationale: Hypothyroidism leads to reduced metabolism, causing
symptoms such as cold intolerance, weight gain, and fatigue.
3. Which of the following is a classic sign of hyperthyroidism?
A. Weight gain
B. Cold intolerance
C. Tachycardia
D. Bradycardia
Answer: C) Tachycardia
Rationale: Hyperthyroidism is characterized by an overproduction
of thyroid hormones, leading to symptoms like tachycardia, heat
intolerance, and weight loss.
,4. Which of the following lab results is most likely in a patient
with dehydration?
A. Low hematocrit
B. Low sodium levels
C. Elevated blood urea nitrogen (BUN)
D. Low creatinine
Answer: C) Elevated blood urea nitrogen (BUN)
Rationale: Dehydration leads to decreased renal perfusion and an
increase in BUN due to reduced fluid volume.
5. What is a common complication of untreated hyperthyroidism?
A. Heart failure
B. Bradycardia
C. Hypoglycemia
D. Myxedema coma
Answer: A) Heart failure
Rationale: Untreated hyperthyroidism can lead to tachycardia and
increased cardiac workload, which can eventually result in heart
failure.
6. What is the most common cause of secondary osteoporosis?
A. Calcium deficiency
B. Hyperparathyroidism
C. Long-term use of corticosteroids
D. Vitamin D deficiency
Answer: C) Long-term use of corticosteroids
Rationale: Long-term corticosteroid use is a major cause of
secondary osteoporosis due to its effect on bone metabolism,
leading to decreased bone density and increased fracture risk.
7. In which of the following conditions would you expect an
increase in erythrocyte sedimentation rate (ESR)?
, A. Acute inflammation
B. Dehydration
C. Iron deficiency anemia
D. Chronic hypertension
Answer: A) Acute inflammation
Rationale: ESR is an indicator of inflammation. It increases during
acute inflammatory processes, such as infections, autoimmune
diseases, and other inflammatory conditions.
8. In which condition would you expect to find a low white blood
cell (WBC) count?
A. Viral infection
B. Leukemia
C. Bacterial infection
D. Bone marrow suppression
Answer: D) Bone marrow suppression
Rationale: Bone marrow suppression, often caused by
chemotherapy or certain diseases, can result in low WBC counts
(leukopenia).
9. What condition is characterized by the failure of the heart to
pump effectively, leading to inadequate tissue perfusion?
A. Stroke
B. Coronary artery disease (CAD)
C. Heart failure
D. Hypertension
Answer: C) Heart failure
Rationale: Heart failure occurs when the heart is unable to pump
blood efficiently, leading to reduced perfusion of tissues and
organs.
10. A nurse is caring for a patient with hyperkalemia. What is the
most concerning sign of this condition?
Addison’s disease?
A. Increased blood pressure
B. Hyperkalemia
C. Weight gain
D. Increased appetite
Answer: B) Hyperkalemia
Rationale: Addison’s disease, a disorder of the adrenal glands,
leads to decreased cortisol and aldosterone production. This
results in fluid and sodium loss and potassium retention, causing
hyperkalemia.
