1. A nurse is caring for a patient with hyperkalemia. What is the
most concerning sign of this condition?
A. Muscle weakness
B. Shortness of breath
C. Diarrhea
D. Nausea
Answer: A) Muscle weakness
Rationale: Hyperkalemia can cause muscle weakness and
potentially life-threatening arrhythmias due to its effect on the
electrical conductivity of the heart.
2. Which of the following is the most common cause of stroke?
A. Aneurysm rupture
B. Ischemia due to a clot
C. Brain tumor
D. Hypertension
Answer: B) Ischemia due to a clot
Rationale: Ischemic strokes are the most common type of stroke
and occur when a clot blocks blood flow to the brain.
3. What is the most common cause of secondary hypertension?
A. Excessive salt intake
B. Renal disease
C. High cholesterol levels
D. Alcohol consumption
Answer: B) Renal disease
Rationale: Secondary hypertension is often caused by another
condition, with renal disease being a leading factor due to
impaired kidney function affecting fluid balance and blood
pressure regulation.
,4. 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.
5. 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.
6. A nurse is assessing a client with a suspected myocardial
infarction (MI). Which finding would be most indicative of an MI?
A. Severe sharp chest pain that radiates to the left shoulder
B. Shortness of breath with a productive cough
C. Gradual onset of bilateral lower leg edema
D. Sudden dizziness with no associated chest pain
Answer: A) Severe sharp chest pain that radiates to the left
shoulder
Rationale: A common symptom of myocardial infarction is chest
pain that radiates to the left shoulder or arm. This is due to
ischemia affecting the heart muscle.
, 7. Which of the following is the most likely cause of anaphylactic
shock?
A. Blood loss
B. Allergic reaction
C. Bacterial infection
D. Spinal cord injury
Answer: B) Allergic reaction
Rationale: Anaphylactic shock is a severe allergic reaction that
causes vasodilation and fluid leakage, leading to hypotension and
shock.
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. 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.
10. What is a key characteristic of Crohn's disease?
most concerning sign of this condition?
A. Muscle weakness
B. Shortness of breath
C. Diarrhea
D. Nausea
Answer: A) Muscle weakness
Rationale: Hyperkalemia can cause muscle weakness and
potentially life-threatening arrhythmias due to its effect on the
electrical conductivity of the heart.
