,Q1. A patient with a history of chronic heart failure (NYHA class III) is admitted with acute dyspnea and
orthopnea. The nurse notes jugular venous distention, bilateral crackles, and an S3 gallop. The patient has
been on a stable dose of lisinopril, carvedilol, and spironolactone. Which hemodynamic principle best
explains the development of pulmonary edema in this patient?
A. Increased systemic vascular resistance due to vasoconstriction
B. Decreased left ventricular compliance leading to elevated left atrial pressure
C. Increased right ventricular afterload causing reduced pulmonary blood flow
D. Decreased myocardial contractility with compensatory tachycardia
Correct Answer: B. Decreased left ventricular compliance leading to elevated left atrial pressure
Rationale: Pulmonary edema in heart failure results from elevated left atrial pressure due to decreased left
ventricular compliance (diastolic dysfunction) or reduced contractility (systolic dysfunction). This pressure is
transmitted backward to the pulmonary capillaries, causing fluid extravasation into the alveoli. Increased SVR (A)
can worsen afterload but is not the direct cause of edema. Right ventricular afterload (C) affects the right side, not
pulmonary edema. Decreased contractility (D) contributes but the key is the pressure gradient.
Why Wrong:
A - Increased SVR raises afterload but does not directly explain pulmonary capillary fluid leak.
C - Increased right ventricular afterload primarily causes right heart failure, not pulmonary edema.
D - Decreased contractility is a factor but the direct mechanism is elevated left atrial pressure.

Q2. A patient in the intensive care unit with acute respiratory distress syndrome (ARDS) is receiving
lung-protective ventilation with a tidal volume of 6 mL/kg ideal body weight and PEEP of 12 cm H2O. The
nurse monitors plateau pressure and driving pressure. Which of the following values would indicate an
increased risk of ventilator-induced lung injury (VILI) and warrant immediate notification of the respiratory
therapist?
A. Plateau pressure 25 cm H2O, driving pressure 13 cm H2O
B. Plateau pressure 30 cm H2O, driving pressure 15 cm H2O
C. Plateau pressure 35 cm H2O, driving pressure 20 cm H2O
D. Plateau pressure 40 cm H2O, driving pressure 25 cm H2O
Correct Answer: D. Plateau pressure 40 cm H2O, driving pressure 25 cm H2O
Rationale: In ARDS, driving pressure (plateau pressure minus PEEP) greater than 15 cm H2O is associated with
increased mortality and VILI. Option D shows a driving pressure of 28 cm H2O (40-12), which is dangerously
high. Plateau pressure should ideally be 30 cm H2O; values >30 cm H2O increase VILI risk. Options A and B have
acceptable driving pressures, and C is borderline but not as critical as D.
Why Wrong:
A - Driving pressure 13 cm H2O is within safe range (<15 cm H2O).
B - Driving pressure 15 cm H2O is at the upper limit but not immediately dangerous.
C - Driving pressure 20 cm H2O is elevated but not as severe as option D.

Q3. A patient with acute kidney injury (AKI) stage 2 (serum creatinine 2.5 mg/dL, urine output 0.3 mL/kg/hr
for 12 hours) is being evaluated for fluid resuscitation. The nurse reviews the following laboratory values:
BUN 45 mg/dL, serum sodium 138 mEq/L, serum potassium 5.6 mEq/L, serum bicarbonate 18 mEq/L. The
patient has received 500 mL of normal saline over 1 hour with no improvement in urine output. Which of the
following is the most appropriate next step in management?
A. Administer furosemide 40 mg IV push
B. Start a dopamine infusion at 2 mcg/kg/min
C. Prepare for hemodialysis
D. Repeat fluid bolus with 500 mL lactated Ringer's




Page 3

, Correct Answer: A. Administer furosemide 40 mg IV push
Rationale: The patient has oliguric AKI with fluid overload (no response to initial fluid bolus) and hyperkalemia. Furosemide
can be used to promote diuresis and manage hyperkalemia, but only after confirming fluid responsiveness. Dopamine at low
doses (B) is not recommended due to lack of evidence. Hemodialysis (C) is indicated for severe hyperkalemia (e.g., >6.5 mEq/L
with ECG changes) or refractory fluid overload, but not yet at this stage. Repeat fluid bolus (D) may worsen fluid overload.
Why Wrong:
B - Low-dose dopamine has no proven benefit in AKI and may cause harm.
C - Hemodialysis is not yet indicated; hyperkalemia is moderate and can be managed medically.
D - Lactated Ringer's contains potassium and could worsen hyperkalemia; also, fluid overload is present.

Q4. A patient with diabetic ketoacidosis (DKA) is being treated with intravenous regular insulin at 0.1
unit/kg/hour and 0.9% normal saline. After 2 hours, the serum glucose has decreased from 650 mg/dL to 480
mg/dL, but the serum potassium is 3.2 mEq/L. The nurse reviews the following arterial blood gas: pH 7.25,
HCO3- 12 mEq/L, PaCO2 28 mm Hg. Which of the following interventions should the nurse anticipate?
A. Increase insulin infusion rate to 0.15 unit/kg/hour
B. Add potassium chloride to the IV fluids and continue insulin
C. Switch to 5% dextrose in 0.45% normal saline
D. Administer sodium bicarbonate 50 mEq IV push
Correct Answer: B. Add potassium chloride to the IV fluids and continue insulin
Rationale: In DKA, total body potassium is depleted despite initial normal or high serum levels due to acidosis. As
insulin drives glucose into cells, potassium follows, causing hypokalemia. Potassium replacement is essential to
prevent cardiac dysrhythmias. Insulin should be continued to resolve ketoacidosis. Increasing insulin (A) would
worsen hypokalemia. Switching to dextrose (C) is indicated when glucose falls to ~250 mg/dL, not yet. Sodium
bicarbonate (D) is reserved for severe acidosis (pH <7.0) and may worsen hypokalemia.
Why Wrong:
A - Increasing insulin would further lower potassium, risking cardiac instability.
C - Dextrose is added when glucose reaches ~250 mg/dL to prevent hypoglycemia, not at 480 mg/dL.
D - Bicarbonate is not indicated for pH >7.0 and can cause paradoxical CSF acidosis.

Q5. A patient with cirrhosis and ascites is admitted with hepatic encephalopathy (West Haven grade II). The
nurse notes asterixis and confusion. Laboratory values: serum ammonia 120 mcg/dL, bilirubin 4.2 mg/dL,
INR 2.1. The patient is started on lactulose. Which of the following best describes the pharmacologic
mechanism by which lactulose reduces serum ammonia?
A. It inhibits bacterial urease in the colon, reducing ammonia production
B. It acidifies the colonic environment, converting NH3 to NH4+ and trapping it in stool
C. It increases renal excretion of ammonia by alkalinizing the urine
D. It enhances hepatic metabolism of ammonia through increased ornithine transcarbamylase activity
Correct Answer: B. It acidifies the colonic environment, converting NH3 to NH4+ and trapping it in stool
Rationale: Lactulose is a nonabsorbable disaccharide that is metabolized by colonic bacteria to lactic and acetic
acids, acidifying the colon. This favors conversion of absorbable ammonia (NH3) to nonabsorbable ammonium
(NH4+), which is trapped in the stool and excreted. Option A describes the mechanism of antibiotics like rifaximin.
Option C is incorrect; lactulose does not affect renal excretion. Option D is not a known mechanism.
Why Wrong:
A - This describes the action of rifaximin, not lactulose.
C - Lactulose does not alkalinize urine; it acidifies the colon.
D - Lactulose does not directly enhance hepatic enzyme activity.
