,Q1. A patient receiving phenelzine (Nardil) reports severe headache, palpitations, and nausea after
eating lunch. Which dietary component most likely caused this reaction?
A. High sodium intake from canned soup
B. Excess tyramine from aged cheese
C. High glucose from fruit juice
D. Excess potassium from bananas
Correct Answer: B. Excess tyramine from aged cheese
Rationale: Phenelzine is a monoamine oxidase inhibitor (MAOI). Ingesting tyramine-rich foods (e.g.,
aged cheese) can precipitate a hypertensive crisis due to reduced tyramine metabolism. Symptoms include
severe headache, palpitations, and nausea. Sodium, glucose, or potassium do not cause this reaction.
Why Wrong:
A - High sodium may contribute to hypertension but does not cause the acute hypertensive crisis
seen with MAOI-tyramine interaction.
C - High glucose ingestion does not interact with MAOIs to produce hypertensive symptoms.
D - Bananas are low in tyramine and do not trigger MAOI reactions; excess potassium is unrelated.

Q2. For a patient with active pulmonary tuberculosis (TB) confirmed by sputum culture, which type
of transmission-based precautions should the nurse initiate?
A. Contact precautions
B. Droplet precautions
C. Airborne precautions
D. Standard precautions only
Correct Answer: C. Airborne precautions
Rationale: Pulmonary tuberculosis is transmitted via airborne droplet nuclei that remain suspended in
the air. Airborne precautions (N95 respirator, negative pressure room) are required. Contact and droplet
precautions are insufficient. Standard precautions are always used but not sufficient alone.
Why Wrong:
A - Contact precautions are for pathogens spread by direct or indirect contact (e.g., C. difficile), not
for TB.
B - Droplet precautions apply to larger droplets that travel short distances (e.g., influenza), not TB.
D - Standard precautions alone cannot prevent inhalation of airborne particles from TB.

,Q3. A patient receiving IV potassium chloride at 10 mEq/hour develops a serum potassium of 6.2
mEq/L. Which ECG change is most likely to be observed?
A. Prolonged PR interval
B. Widened QRS complex
C. Peaked T waves
D. ST segment depression
Correct Answer: C. Peaked T waves
Rationale: Hyperkalemia (K+ >5.5) characteristically produces peaked, symmetrical T waves on ECG.
As K+ rises, QRS widens and P waves flatten, but peaked T waves are the earliest sign. Prolonged PR is
more common in hypokalemia or heart block. ST depression is seen in ischemia or hypokalemia.
Why Wrong:
A - Prolonged PR interval is typically associated with hypokalemia or first-degree AV block, not
hyperkalemia.
B - Widened QRS occurs in severe hyperkalemia but is a later finding, not the most likely initially.
D - ST segment depression is associated with ischemia or hypokalemia, not hyperkalemia.

Adults and Children, 8th Ed., Ch. 33
Q4. During a wound assessment, the nurse notes full-thickness tissue loss with visible subcutaneous
fat. The wound bed is viable but no bone, tendon, or muscle is exposed. Which pressure ulcer stage
is this?
A. Stage 1
B. Stage 2
C. Stage 3
D. Unstageable
Correct Answer: C. Stage 3
Rationale: A stage 3 pressure ulcer involves full-thickness skin loss with visible subcutaneous fat; bone,
tendon, or muscle are not exposed. Stage 2 is partial-thickness with dermal involvement. Stage 1 is intact
skin with nonblanchable erythema. Unstageable has full-thickness loss obscured by slough or eschar.
Why Wrong:
A - Stage 1 presents as intact skin with nonblanchable erythema, no tissue loss.
B - Stage 2 involves partial-thickness skin loss with exposed dermis, not full thickness.
D - Unstageable has full-thickness loss but the depth is obscured by slough or eschar, unlike this
description.

, Q5. A nurse supervisor delegates medication administration to an LPN. The LPN discovers that a
prescribed dose of a high-alert medication exceeds the standard safe range. What is the LPN's best
action?
A. Administer the medication as prescribed
B. Refuse to administer and notify the supervising RN or prescriber
C. Hold the medication and document as refused by the patient
D. Administer a lower dose within safe range and alert the prescriber later
Correct Answer: B. Refuse to administer and notify the supervising RN or prescriber
Rationale: LPNs have a duty to ensure medication safety. If a dose appears unsafe, they must withhold
and report to the supervising RN or prescriber. Administering as prescribed (A) violates safety; lowering
dose (D) is beyond LPN scope; documenting as patient refusal (C) is false documentation.
Why Wrong:
A - Administering an unsafe dose violates the LPN's responsibility to protect the patient.
C - Documenting refusal is inaccurate if the patient did not refuse; this is falsification.
D - Altering a dose without an order is outside LPN scope of practice.

Practice.
Q6. A patient receiving total parenteral nutrition (TPN) suddenly develops dyspnea, chest pain, and
cyanosis. The nurse suspects an air embolism. Which immediate action should the nurse take?
A. Increase the TPN infusion rate
B. Place the patient in left lateral Trendelenburg position
C. Administer oxygen via nasal cannula at 2 L/min
D. Clamp the catheter and notify the provider
Correct Answer: B. Place the patient in left lateral Trendelenburg position
Rationale: In suspected air embolism, placing the patient in left lateral Trendelenburg position traps air
in the right ventricle and prevents passage to pulmonary circulation. Clamping the catheter (D) may be
done later but positioning is critical. Increasing rate (A) could worsen embolism. Oxygen is supportive
but not the priority.
Why Wrong:
A - Increasing TPN rate could introduce more air and worsen the embolism.
C - Oxygen is important but positioning to trap air takes precedence.
D - Clamping the catheter alone does not address the air already in the circulation; positioning is
needed.
