AND ANSWERS. VERIFIED
1. A nurse is caring for a patient who refuses a scheduled blood transfusion for religious
reasons. Which ethical principle is the nurse upholding by respecting this decision?
A. Beneficence
B. Justice
C. Nonmaleficence
D. Autonomy
Answer: D
Conceptual Explanation: Autonomy refers to the right of the patient to make their own
decisions regarding their healthcare, even if the healthcare provider disagrees.
2. A patient presents with a serum potassium level of 6.2 mEq/L. Which of the following
clinical manifestations should the nurse prioritize for monitoring?
A. Cardiac dysrhythmias
B. Hyperactive bowel sounds
C. Increased muscle strength
D. Polyuria
,Answer: A
Conceptual Explanation: Hyperkalemia (potassium > 5.0 mEq/L) can cause life-
threatening cardiac dysrhythmias and EKG changes, such as peaked T waves.
3. Which of the following is the most reliable method for verifying the initial placement of a
nasogastric (NG) tube?
A. Auscultation of an air bolus
B. Radiographic (X-ray) confirmation
C. Testing the pH of aspirated gastric contents
D. Observing for respiratory distress
Answer: B
Conceptual Explanation: Radiographic confirmation is the gold standard for verifying the
correct placement of an NG tube before administering fluids or medications.
4. A nurse is administering Digoxin to a patient with heart failure. Which assessment finding
would indicate Digoxin toxicity?
A. Visual disturbances, such as yellow halos
B. Hypotension
C. Tachycardia
D. Hyperglycemia

control measure is mandatory?
A. Washing hands with soap and water
B. Using alcohol-based hand sanitizer after care
C. Wearing an N95 respirator

Answer: A
Conceptual Explanation: C. diff spores are resistant to alcohol-based sanitizers; therefore,
mechanical friction with soap and water is required for hand hygiene.
6. During the shift report, the nurse learns a patient has a ‘Stage 3 pressure injury.’ How
should the nurse expect the wound to appear?
A. Full-thickness tissue loss with visible subcutaneous fat
B. Partial-thickness loss of dermis
C. Non-blanchable erythema of intact skin
D. Full-thickness tissue loss with exposed bone or muscle
Answer: A
