Questions & Verified Answers
1. A patient presents with a pH of 7.31, PaCO2 of 52 mmHg, and HCO3 of 25 mEq/L. Which
acid-base imbalance is the patient experiencing?
A. Metabolic Acidosis
B. Respiratory Alkalosis
C. Metabolic Alkalosis
D. Respiratory Acidosis
Answer: D
Rationale: A pH below 7.35 indicates acidosis. A PaCO2 above 45 mmHg indicates the cause is respiratory.
Since the HCO3 is normal, it is uncompensated respiratory acidosis. Exam questions often test the ability to
distinguish this concept from closely related distractors, making a clear rationale essential for mastery.
2. Which electrolyte imbalance is most likely to cause a positive Chvostek’s sign?
A. Hyperkalemia
B. Hyponatremia
C. Hypocalcemia
D. Hypermagnesemia
Answer: C
Rationale: Hypocalcemia increases neuromuscular excitability, which can lead to Chvostek’s sign (facial
twitching when the facial nerve is tapped). Recognizing this principle allows the nurse to prioritize care,
anticipate complications, and provide accurate patient education. Exam questions often test the ability to
distinguish this concept from closely related distractors, making a clear rationale essential for mastery.
3. A patient is admitted with a potassium level of 6.2 mEq/L. Which ECG change should the
nurse monitor for?
A. Prominent U waves
B. Peaked T waves
C. Flat T waves
D. Shortened PR interval
Answer: B
Rationale: Hyperkalemia (K+ > 5.0) causes tall, peaked T waves, widened QRS complexes, and potentially
cardiac arrest. Exam questions often test the ability to distinguish this concept from closely related distractors,
making a clear rationale essential for mastery. Applying this knowledge in clinical settings supports safe,
evidence-based practice and improves patient outcomes.

4. Which of the following is a primary clinical manifestation of fluid volume deficit?
A. Bounding pulse
B. Distended neck veins
C. Crackles in the lungs
D. Orthostatic hypotension
Answer: D
Rationale: Fluid volume deficit leads to decreased circulating volume, causing orthostatic hypotension, weak
thready pulses, and poor skin turgor. Recognizing this principle allows the nurse to prioritize care, anticipate
complications, and provide accurate patient education. Exam questions often test the ability to distinguish this
concept from closely related distractors, making a clear rationale essential for mastery.
5. A patient with a stage 3 pressure injury is being assessed. What characterizes this stage?
A. Non-blanchable erythema of intact skin
B. Full-thickness skin loss involving damage to subcutaneous tissue
C. Partial-thickness loss of dermis
D. Full-thickness tissue loss with exposed bone or muscle
Answer: B
Rationale: Stage 3 involves full-thickness skin loss where fat may be visible, but bone, tendon, or muscle are
not exposed. Exam questions often test the ability to distinguish this concept from closely related distractors,
making a clear rationale essential for mastery. Applying this knowledge in clinical settings supports safe,
evidence-based practice and improves patient outcomes.
6. What is the primary purpose of a ‘time-out’ in the operating room?
A. To allow the surgeon to rest
B. To ensure the patient has signed the consent
C. To verify the correct patient, site, and procedure
D. To check if the anesthesia equipment is working
Answer: C
Rationale: The ‘time-out’ is a safety protocol to prevent wrong-site, wrong-procedure, and wrong-person
surgery. Exam questions often test the ability to distinguish this concept from closely related distractors, making
a clear rationale essential for mastery. Applying this knowledge in clinical settings supports safe,
evidence-based practice and improves patient outcomes.
