,Q1. A patient with hypercalcemia due to malignancy is admitted. The provider orders intravenous
normal saline at 200 mL/hr, furosemide 40 mg IV push, and pamidronate 90 mg IV over 2 hours.
Which intervention is most critical to implement first?
A. Initiate IV normal saline as ordered.
B. Administer furosemide 40 mg IV push.
C. Start pamidronate 90 mg IV infusion.
D. Obtain a serum calcium level before any treatment.
Correct Answer: A. Initiate IV normal saline as ordered.
Rationale: In hypercalcemia, volume depletion exacerbates calcium concentration; rehydration with
normal saline is the priority to dilute serum calcium and improve renal perfusion. Furosemide is only
given after adequate volume repletion to avoid hypovolemia. Pamidronate is a bisphosphonate that
lowers calcium but takes 2-4 days; it is not the first step. Obtaining labs is important but does not
supersede initiating treatment.
Why Wrong:
B - Furosemide should be given only after volume repletion; giving it first risks dehydration and
acute kidney injury.
C - Pamidronate is a long-term intervention and not the immediate priority for acute hypercalcemia.
D - While baseline labs are needed, treatment should not be delayed; the calcium level is already
known from admission labs.

Q2. A patient with severe metabolic acidosis (pH 7.15, HCO3- 8 mEq/L, PaCO2 25 mm Hg) is being
treated with sodium bicarbonate. Which assessment finding indicates a potential complication of
this therapy?
A. Decreased serum potassium level.
B. Increased PaCO2 with worsening acidosis.
C. Development of tetany and positive Chvostek sign.
D. Rising serum sodium level and peripheral edema.
Correct Answer: C. Development of tetany and positive Chvostek sign.
Rationale: Rapid correction of acidosis with bicarbonate can cause ionized hypocalcemia because
bicarbonate shifts calcium to protein-bound forms, leading to tetany, Chvostek sign, and Trousseau sign.
This is a known complication of sodium bicarbonate therapy, especially in patients with renal failure or
underlying hypocalcemia. Option A is incorrect because alkalosis shifts potassium intracellularly, not
acidosis. Option B (increased PaCO2) can occur if ventilation is inadequate, but the primary concern is
hypocalcemia.
Why Wrong:
A - Hypokalemia is more likely with alkalosis, not with bicarbonate administration for acidosis.
B - Worsening acidosis with increased PaCO2 may indicate inadequate ventilation, but it is not the
most specific complication of bicarbonate therapy.
D - Hypernatremia and edema can occur with excessive sodium bicarbonate, but tetany is the classic
acute complication.

, Q3. A patient is to receive heparin 18 units/kg/hr via continuous infusion. The patient weighs 176 lb.
The pharmacy supplies heparin 25,000 units in 500 mL of D5W. Calculate the infusion rate in
mL/hr (round to the nearest tenth).
A. 28.8 mL/hr
B. 32.0 mL/hr
C. 14.4 mL/hr
D. 16.0 mL/hr
Correct Answer: A. 28.8 mL/hr
Rationale: Weight in kg: 176 lb ÷ 2.2 = 80 kg. Dose per hour: 18 units/kg/hr × 80 kg = 1440 units/hr.
Concentration: 25,000 units/500 mL = 50 units/mL. Infusion rate: 1440 units/hr ÷ 50 units/mL = 28.8
mL/hr. Option B (32 mL/hr) corresponds to 20 units/kg/hr. Option C (14.4 mL/hr) is half the correct rate.
Option D (16 mL/hr) corresponds to 10 units/kg/hr.
Why Wrong:
B - This rate would deliver 20 units/kg/hr, which is higher than ordered.
C - This rate is half the correct rate, likely from miscalculating weight or concentration.
D - This rate corresponds to 10 units/kg/hr, which is too low.

Q4. During a preoperative assessment, a patient reports taking St. John's wort daily for depression.
The nurse understands that this herb interacts with which anesthetic agent, potentially causing
delayed emergence?
A. Propofol
B. Sevoflurane
C. Succinylcholine
D. Midazolam
Correct Answer: D. Midazolam
Rationale: St. John's wort induces cytochrome P450 enzymes (CYP3A4), accelerating the metabolism of
midazolam, a benzodiazepine commonly used for sedation and anesthesia. This can lead to reduced
efficacy and delayed emergence due to altered metabolism. Propofol is metabolized mainly by
conjugation, not CYP3A4. Sevoflurane is inhaled and minimally metabolized. Succinylcholine is
metabolized by plasma pseudocholinesterase.
Why Wrong:
A - Propofol metabolism is not significantly affected by St. John's wort.
B - Sevoflurane is an inhaled anesthetic with minimal hepatic metabolism.
C - Succinylcholine is metabolized by pseudocholinesterase, not CYP enzymes.
