Legal/ethical Issues
Q1.
A patient with acute respiratory distress syndrome (ARDS) is on volume-controlled
ventilation with a tidal volume of 6 mL/kg ideal body weight. Plateau pressure is 30 cm
H2O, and PaCO2 is 55 mm Hg with pH 7.30. Which intervention should the nurse
anticipate to improve ventilation without increasing ventilator-induced lung injury?
A. Increase tidal volume to 8 mL/kg B. Increase respiratory rate to 28
breaths/min
C. Switch to pressure-controlled ventilation D. Administer neuromuscular blocking agent
Correct: B - Increase respiratory rate to 28 breaths/min
Rationale:Increasing respiratory rate can lower PaCO2 without raising plateau pressure, thus
avoiding volutrauma. Increasing tidal volume would increase plateau pressure and risk lung
injury. Switching modes does not directly improve ventilation. Neuromuscular blockade may
improve oxygenation but does not primarily address ventilation.
Q2.
A patient receiving furosemide for heart failure develops muscle cramps and a serum
potassium level of 3.2 mEq/L. The nurse reviews the medication administration record.
Which PRN medication should the nurse question?
A. Acetaminophen 650 mg PO B. Digoxin 0.125 mg IV
C. Metoprolol 25 mg PO D. Lorazepam 1 mg IV
Correct: B - Digoxin 0.125 mg IV
Rationale:Hypokalemia increases the risk of digoxin toxicity, which can cause life-threatening
arrhythmias. Digoxin should be withheld until potassium is corrected. Acetaminophen,
metoprolol, and lorazepam are not directly affected by hypokalemia.
Q3.
A patient with cirrhosis and ascites has a serum sodium of 128 mEq/L and is receiving
spironolactone. The nurse notes progressive confusion and asterixis. Which intervention
is most appropriate?
A. Administer 3% hypertonic saline IV B. Increase spironolactone dose
C. Administer lactulose enema D. Restrict oral fluids to 1 L/day
Correct: C - Administer lactulose enema
Page 3
, Section A - Professional Responsibilities AND Legal/ethical Issues
Rationale: The patient likely has hepatic encephalopathy precipitated by hyponatremia.
Lactulose reduces ammonia levels and improves encephalopathy. Hypertonic saline may
correct sodium but does not address encephalopathy. Increasing spironolactone could worsen
hyponatremia. Fluid restriction is slow and does not acutely treat encephalopathy.
Q4.
A patient with septic shock on norepinephrine has a mean arterial pressure (MAP) of 58
mm Hg, central venous pressure (CVP) of 12 mm Hg, and ScvO2 of 65%. After fluid
resuscitation, which intervention should the nurse implement next?
A. Start vasopressin infusion B. Administer dobutamine infusion
C. Transfuse packed red blood cells D. Increase norepinephrine rate
Correct: A - Start vasopressin infusion
Rationale:With adequate CVP (fluid status) and low MAP despite norepinephrine, adding
vasopressin is recommended as a second vasopressor. Dobutamine is for low cardiac output;
ScvO2 is normal. Transfusion is indicated if hemoglobin <7 g/dL. Increasing norepinephrine
further may cause excessive vasoconstriction.
Q5.
A patient with a history of type 2 diabetes presents with nausea, vomiting, and abdominal
pain. Blood glucose is 650 mg/dL, serum pH 7.1, bicarbonate 12 mEq/L, and ketones
present. Serum osmolality is 320 mOsm/kg. Which intravenous fluid should the nurse
prepare to administer first?
A. 0.9% sodium chloride at 15 mL/kg/hour B. 0.45% sodium chloride at 250 mL/hour
C. 5% dextrose in water at 100 mL/hour D. Lactated Ringer's solution at 500
mL/hour
Correct: A - 0.9% sodium chloride at 15 mL/kg/hour
Rationale:This is diabetic ketoacidosis (DKA) with hyperosmolarity. Initial fluid resuscitation
should be with 0.9% normal saline to correct hypovolemia and reduce osmolality gradually.
0.45% saline is used after volume expansion. D5W is given when glucose drops. Lactated
Ringer's may worsen acidosis.
Q6.
A patient with acute kidney injury (AKI) due to contrast nephropathy has a urine output of
20 mL/hour, BUN 80 mg/dL, creatinine 4.5 mg/dL, and potassium 6.0 mEq/L. ECG shows
peaked T waves. Which intervention should the nurse implement first?
A. Administer sodium polystyrene sulfonate B. Start continuous renal replacement
orally therapy
