Questions & Verified Answers
1. A client with a history of heart failure presents with a cough, shortness of breath, and
crackles in the lungs. Which of the following laboratory values is most specific in confirming
an exacerbation of heart failure?
A. Creatinine kinase-MB (CK-MB)
B. B. Troponin I
C. B-type natriuretic peptide (BNP)
D. C-reactive protein (CRP)
Answer: C
Rationale: BNP is a hormone secreted by cardiomyocytes in the heart ventricles in response to
stretching caused by increased ventricular blood volume. It is highly specific for heart failure. Exam
questions often test whether you can pick the most practical and safe choice for the client in real
situations. Focus on what the nurse can actually do right now. Remembering this point will help you
decide the best nursing action when similar questions appear on the exam. Link the answer to the
client’s current condition and risk level.
2. The nurse is caring for a client with a spinal cord injury at the T4 level. The client reports a
sudden, severe headache and is noted to have a blood pressure of 190/100 mmHg. Which
action should the nurse take first?
A. Administer an antihypertensive medication
B. Check the client’s bladder for distension
C. Assess the client for a fecal impaction
D. Elevate the head of the bed to 90 degrees
Answer: D
Rationale: The client is showing signs of autonomic dysreflexia. The priority intervention is to elevate
the head of the bed to lower blood pressure through postural hypotension before addressing the cause
(like bladder distension). In practice, this guides the nurse to set priorities and protect the client from
harm. Safety, nutrition, and clear communication are frequent priorities. Clear understanding of this
concept improves both test performance and everyday clinical judgment. Practice applying it to short
case scenarios to lock the idea in place.

3. A client is prescribed Lithium Carbonate for the treatment of bipolar disorder. Which of the
following findings should the nurse identify as a sign of lithium toxicity?
A. Weight gain and fine hand tremors
B. Mild thirst and polyuria
C. Increased white blood cell count
D. Ataxia, blurred vision, and severe diarrhea
Answer: D
Rationale: Ataxia, blurred vision, and severe GI upset are classic signs of lithium toxicity (levels
usually > 1.5 mEq/L). Weight gain and fine tremors are common side effects, not necessarily toxicity.
Understanding this helps the nurse notice early warning signs and act before the problem gets worse.
Early action often prevents bigger complications for the client. Knowing the reason behind the correct
answer makes it easier to rule out the wrong options quickly. Look for the choice that protects the client
and matches the priority need.
4. A nurse is caring for a 4-year-old child following a tonsillectomy. Which of the following
observations is the most reliable indicator of postoperative hemorrhage?
A. Decreased blood pressure
B. Increased crying and irritability
C. Frequent swallowing
D. Reporting a sore throat
Answer: C
Rationale: Frequent swallowing is a sign that the child is swallowing blood from the surgical site.
Blood pressure drop is a late sign of shock in children. This knowledge supports safe care and helps
the nurse teach the client and family clearly and simply. Clear teaching improves cooperation and
reduces anxiety. Clear understanding of this concept improves both test performance and everyday
clinical judgment. Practice applying it to short case scenarios to lock the idea in place.
