CHAMBERLAIN COLLEGE OF
NURSING |100% CORRECT Q & A|
1. How often should a CK (creatine kinase) level be measured in suspected
rhabdomyolysis, and why?
A. Every 24 hours to monitor long-term trends
B. Only once at presentation
C. Every 6–12 hours to identify peak levels and monitor the downward trend ✔️
D. Only if urine output decreases
Rationale: CK levels rise rapidly after muscle injury and peak within 24–72 hours. Frequent
measurement every 6–12 hours helps detect peak values and track improvement, guiding
interventions to prevent kidney injury.
2. A 26-year-old marathon runner presents with dark urine, nausea, vomiting,
and muscle soreness. Which test confirms rhabdomyolysis?
A. Serum creatinine
B. Serum myoglobin
C. Serum creatine kinase ✔️
D. Urinalysis for ketones
Rationale: Serum CK is the most sensitive and specific laboratory marker for diagnosing
rhabdomyolysis. Myoglobin may be elevated but is less specific, and urinalysis is supportive but
not diagnostic.
3. In rhabdomyolysis, which electrolyte abnormality should you anticipate based
on EKG changes showing peaked T waves and prolonged PR/QRS intervals?
1
,A. Hypokalemia
B. Hyperkalemia ✔️
C. Hypocalcemia
D. Hyponatremia
Rationale: Muscle breakdown releases intracellular potassium into the bloodstream, causing
hyperkalemia, which is reflected on EKG as tall peaked T waves, widened QRS, and PR
prolongation.
4. Which of the following is a risk factor for acute intestinal obstruction?
A. Viral infections
B. Adhesions from previous surgery ✔️
C. Migraine
D. Hyperthyroidism
Rationale: Prior abdominal surgery can cause adhesions, leading to obstruction. Other risk
factors include hernias, neoplasms, trauma, and congenital anomalies.
5. A client presents with colicky abdominal pain, vomiting, bloating, and
obstipation. Which objective findings may indicate intestinal obstruction?
A. High-pitched bowel sounds, abdominal distention, signs of shock ✔️
B. Hyperactive bowel sounds only
C. Jaundice and scleral icterus
D. Skin rash and pruritus
Rationale: Intestinal obstruction presents with hyperactive or high-pitched bowel sounds
initially, progressing to hypoactive/absent sounds in complete obstruction. Abdominal distention,
tenderness, and shock may indicate severe obstruction or ischemia.
6. Why is serum lactate measured in suspected bowel obstruction?
A. To detect electrolyte imbalance
B. To assess liver function
C. To identify strangulation or ischemia ✔️
D. To monitor hydration status
2
, Rationale: Elevated lactate suggests tissue hypoperfusion or ischemia, which is critical in
detecting strangulated bowel obstruction requiring urgent intervention.
7. Which imaging modality is first-line for suspected bowel obstruction?
A. MRI abdomen
B. Plain film X-ray ✔️
C. Barium swallow
D. Ultrasound
Rationale: Plain abdominal X-ray is quick, accessible, and can reveal dilated loops of bowel
with air-fluid levels. Barium is contraindicated in high-grade obstruction due to risk of
worsening blockage.
8. Superior Vena Cava Syndrome (SVCS) is most commonly caused by:
A. Infectious mononucleosis
B. Autoimmune disorders
C. Malignant tumors (lung cancer, lymphoma) ✔️
D. Pulmonary embolism
Rationale: Malignancies compressing or invading the SVC are the predominant cause.
Symptoms include facial/neck swelling, dyspnea, cough, and dilated chest veins.
9. Which positions can worsen SVCS symptoms?
A. Sitting upright
B. Lying supine or bending forward ✔️
C. Walking
D. Standing
Rationale: Lying flat or bending increases venous return to the compressed SVC, exacerbating
facial and upper extremity edema.
10. What is the hallmark clinical feature of acute mesenteric ischemia (AMI)?
