,Q1. A patient with acute coronary syndrome is started on a continuous heparin infusion. The nurse reviews
the laboratory results: aPTT 45 seconds (control 30 seconds), platelet count 180,000/mm³, and aPTT 6 hours
ago was 40 seconds. The current infusion rate is 12 units/kg/hr. The nurse should anticipate which provider
action?
A. Increase the heparin infusion rate by 2 units/kg/hr
B. Administer a bolus of heparin 5000 units and increase infusion by 2 units/kg/hr
C. Obtain a stat platelet count and initiate argatroban
D. Discontinue heparin and start bivalirudin
Correct Answer: A. Increase the heparin infusion rate by 2 units/kg/hr
Rationale: The current aPTT (45 sec) is below the therapeutic range (typically 1.5-2.5 times control, so 45-75 sec).
Therefore, the infusion rate should be increased per protocol. A bolus is not indicated as the aPTT is only slightly
subtherapeutic. Options C and D are for heparin-induced thrombocytopenia (HIT); platelet count is normal, so HIT
is not present.
Why Wrong:
B - A bolus is not indicated because the aPTT is only slightly subtherapeutic; a bolus could cause
over-anticoagulation.
C - There is no evidence of HIT (platelet count normal, no thrombosis), so argatroban is not indicated.
D - Bivalirudin is used for HIT or as an alternative in certain cases; not indicated here.

Problems, 12th ed., Ch. 36.
Q2. A patient with end-stage renal disease (ESRD) receiving hemodialysis three times per week is admitted
with hyperkalemia (potassium 6.5 mEq/L). The nurse administers intravenous calcium gluconate, insulin,
and dextrose. What is the primary rationale for administering calcium gluconate in this situation?
A. To enhance renal excretion of potassium
B. To shift potassium into the intracellular compartment
C. To stabilize the cardiac membrane and prevent arrhythmias
D. To bind with potassium and form an insoluble complex
Correct Answer: C. To stabilize the cardiac membrane and prevent arrhythmias
Rationale: Calcium gluconate does not lower serum potassium but protects the heart by stabilizing the myocardial
cell membrane, reducing the risk of life-threatening arrhythmias. Insulin and dextrose shift potassium into cells,
while dialysis removes potassium. Calcium does not enhance excretion, shift potassium, or bind to it.
Why Wrong:
A - Calcium does not enhance renal excretion; dialysis and loop diuretics do.
B - Insulin and beta-agonists shift potassium intracellularly; calcium does not.
D - Calcium does not bind potassium; sodium polystyrene sulfonate binds potassium in the gut.
Reference: Lehne, R. A. (2026). Pharmacology for Nursing Care, 12th ed., Ch. 56.
Q3. A patient with a history of chronic obstructive pulmonary disease (COPD) is admitted with acute
respiratory failure. Arterial blood gas results: pH 7.25, PaCO2 60 mm Hg, PaO2 55 mm Hg, HCO3- 26
mEq/L. The nurse initiates noninvasive positive pressure ventilation (NIPPV). Which finding indicates a need
to discontinue NIPPV and prepare for intubation?
A. Patient becomes confused and agitated
B. Respiratory rate decreases from 28 to 22 breaths/min
C. PaCO2 decreases to 52 mm Hg after 2 hours
D. SpO2 improves from 88% to 94% on 40% FiO2
Correct Answer: A. Patient becomes confused and agitated
Rationale: Worsening mental status (confusion, agitation) indicates hypercapnic encephalopathy or failure of
NIPPV, necessitating intubation. Option B shows improvement (lower rate), C shows improved ventilation (PaCO2
Page 3
, drop), D shows improved oxygenation. All are signs of effective NIPPV.
Why Wrong:
B - A decreasing respiratory rate indicates reduced work of breathing and improved ventilation, a positive sign.
C - A drop in PaCO2 indicates improved alveolar ventilation, a goal of NIPPV.
D - Improved SpO2 indicates better oxygenation, a positive response.
Reference: Urden, L. D., et al. (2026). Critical Care Nursing: Diagnosis and Management, 9th ed., Ch. 14.
Q4. A patient is admitted with diabetic ketoacidosis (DKA). Serum glucose is 650 mg/dL, potassium 4.0
mEq/L, pH 7.1, bicarbonate 10 mEq/L, and anion gap 20. The nurse starts an insulin infusion at 0.1
unit/kg/hr. One hour later, the glucose is 450 mg/dL, potassium 3.2 mEq/L. Which action should the nurse
take?
A. Increase insulin infusion to 0.2 unit/kg/hr
B. Decrease insulin infusion to 0.05 unit/kg/hr and add dextrose to IV fluids
C. Continue current insulin infusion and administer IV potassium
D. Discontinue insulin infusion and administer 50% dextrose
Correct Answer: B. Decrease insulin infusion to 0.05 unit/kg/hr and add dextrose to IV fluids
Rationale: When glucose falls below 300 mg/dL, insulin infusion is typically reduced to prevent hypoglycemia, and
dextrose is added to maintain glucose around 200-300 mg/dL while correcting acidosis. The potassium level is low
(3.2), but the priority is to prevent hypoglycemia; potassium should also be replaced, but the question asks for the
action regarding insulin. Option B is correct per DKA protocols.
Why Wrong:
A - Increasing insulin could cause rapid hypoglycemia; glucose is already falling.
C - Continuing the same rate may lead to hypoglycemia; potassium replacement is needed but the insulin
adjustment is primary.
D - Discontinuing insulin would halt correction of acidosis; dextrose alone is insufficient.

49(Suppl 1), S1-S212.
Q5. A patient with cirrhosis and ascites is receiving spironolactone 100 mg daily. The nurse notes a serum
potassium of 5.8 mEq/L and the patient reports muscle cramps. Which intervention is most appropriate?
A. Hold the spironolactone and administer furosemide 40 mg IV
B. Continue spironolactone and administer oral potassium supplements
C. Hold spironolactone and administer sodium polystyrene sulfonate
D. Increase spironolactone to 200 mg daily and monitor potassium
Correct Answer: A. Hold the spironolactone and administer furosemide 40 mg IV
Rationale: Spironolactone is a potassium-sparing diuretic; hyperkalemia is a known adverse effect. The patient has
significant hyperkalemia (5.8) with symptoms (muscle cramps). The nurse should hold spironolactone and consider
a loop diuretic like furosemide to promote potassium excretion. Potassium supplements are contraindicated.
Sodium polystyrene sulfonate is not first-line and slower. Increasing spironolactone would worsen hyperkalemia.
Why Wrong:
B - Potassium supplements would exacerbate hyperkalemia; spironolactone should be held.
C - Sodium polystyrene sulfonate can be used but is slower; furosemide is more appropriate for acute
management.
D - Increasing spironolactone would worsen hyperkalemia.
