CADUCEUS FINAL EXAM QUESTIONS AND
CORRECT ANSWERS WITH RATIONALES
GRADED A+ LATEST
1. A nurse is caring for a patient with chest pain radiating to the left arm.
Which initial action is the priority?
A. Obtain a full pain history
B. Administer prescribed morphine
C. Apply oxygen and assess vital signs
D. Prepare the patient for cardiac catheterization
Correct Answer: C
Rationale: Airway, breathing, and circulation (ABCs) take priority. Oxygen and
vital sign assessment are immediate interventions in suspected cardiac events.
2. A patient with diabetes reports numbness and tingling in both feet. This
finding is most consistent with:
A. Acute hypoglycemia
B. Peripheral neuropathy
C. Peripheral vascular disease
D. Autonomic dysreflexia
Correct Answer: B
Rationale: Chronic hyperglycemia damages peripheral nerves, leading to
numbness and tingling (diabetic neuropathy).
,3. A nurse reviews a medication order for a patient with renal failure. Which
drug requires the most careful monitoring?
A. Acetaminophen
B. Furosemide
C. Gentamicin
D. Aspirin
Correct Answer: C
Rationale: Aminoglycosides are nephrotoxic and require close monitoring in renal
impairment.
4. A patient suddenly develops shortness of breath, chest pain, and
hemoptysis. The nurse suspects:
A. Pneumonia
B. Pulmonary embolism
C. Heart failure
D. Myocardial infarction
Correct Answer: B
Rationale: Classic signs of pulmonary embolism include acute dyspnea, chest
pain, and hemoptysis.
5. Which assessment finding best indicates effective pain management?
A. Decreased heart rate
B. Patient states pain is 2/10
C. Patient appears relaxed
D. Absence of grimacing
Correct Answer: B
Rationale: Pain is subjective; the patient’s self-report is the most reliable
indicator.
,6. A nurse is caring for a patient with a sodium level of 128 mEq/L. Which
symptom is most concerning?
A. Muscle cramps
B. Confusion
C. Dry mucous membranes
D. Increased thirst
Correct Answer: B
Rationale: Hyponatremia affects neurological function, leading to confusion and
risk of seizures.
7. Which infection control measure is most effective in preventing hospital-
acquired infections?
A. Wearing gloves
B. Proper hand hygiene
C. Using sterile technique
D. Isolating all patients
Correct Answer: B
Rationale: Hand hygiene is the single most effective method to prevent infection
transmission.
8. A patient with asthma uses a short-acting beta-agonist inhaler daily. This
indicates:
A. Proper asthma control
B. Overuse of medication
C. Need for inhaled corticosteroids
D. Normal disease progression
Correct Answer: C
Rationale: Frequent rescue inhaler use suggests poor control and need for long-
term anti-inflammatory therapy.
, 9. Which finding indicates early hypovolemic shock?
A. Bradycardia
B. Hypotension
C. Narrowed pulse pressure
D. Decreased urine output
Correct Answer: D
Rationale: Reduced renal perfusion leads to decreased urine output early in shock.
10. A patient with heart failure has crackles, edema, and dyspnea. Which
intervention is most appropriate?
A. Increase IV fluids
B. Place patient supine
C. Administer diuretics
D. Encourage oral intake
Correct Answer: C
Rationale: Diuretics reduce fluid overload and improve symptoms of heart failure.
11. A nurse prepares to administer insulin. Which site allows the fastest
absorption?
A. Thigh
B. Abdomen
C. Upper arm
D. Buttocks
Correct Answer: B
Rationale: The abdomen provides the most consistent and rapid insulin
absorption.
