,Q1. A patient with septic shock is on a norepinephrine infusion titrated to maintain a
mean arterial pressure (MAP) of 65 mm Hg. The patient's blood pressure is 82/50
mm Hg, heart rate is 128 bpm, and central venous pressure is 4 mm Hg. Which
additional intervention should the nurse anticipate?
A. Administer a 500 mL bolus of 0.9% sodium chloride
B. Increase the norepinephrine infusion rate
C. Administer an IV dose of furosemide
D. Start an infusion of sodium bicarbonate
Correct Answer: A. Administer a 500 mL bolus of 0.9% sodium chloride
Rationale: In septic shock, initial fluid resuscitation with crystalloids is recommended to
restore intravascular volume and improve tissue perfusion. The low CVP suggests
hypovolemia; therefore, a fluid bolus is indicated before further vasopressor escalation.
Increasing norepinephrine without adequate volume may worsen hypoperfusion.
Furosemide and sodium bicarbonate are not indicated in this scenario.
Why Wrong:
B - Increasing vasopressor dose without addressing hypovolemia can exacerbate tissue
ischemia and is not the priority.
C - Furosemide would further reduce preload and is contraindicated in hypovolemic
shock.
D - Sodium bicarbonate is not indicated unless severe metabolic acidosis (pH <7.15)
is present; it does not address the underlying hypoperfusion.

Q2. A patient with acute pancreatitis has a serum calcium of 6.8 mg/dL and a positive
Chvostek's sign. Which assessment finding requires immediate nursing action?
A. Intermittent abdominal pain radiating to the back
B. Muscle twitching and carpopedal spasm
C. Elevated serum lipase level
D. Hypoactive bowel sounds
Correct Answer: B. Muscle twitching and carpopedal spasm
Rationale: Hypocalcemia in acute pancreatitis can lead to tetany, manifested by muscle
twitching and carpopedal spasm. This indicates severe hypocalcemia and risk of laryngeal
spasm or seizures, requiring immediate IV calcium replacement. Abdominal pain, elevated
lipase, and hypoactive bowel sounds are consistent with pancreatitis but do not represent
an immediate life-threatening complication.
Why Wrong:
A - Abdominal pain is a hallmark of pancreatitis but is not the most immediate threat
compared to tetany.
C - Elevated lipase confirms pancreatitis but does not require immediate intervention.
Page 3
, D - Hypoactive bowel sounds are common in pancreatitis due to ileus and are not
immediately dangerous.

Q3. A patient with chronic kidney disease (CKD) stage 4 is prescribed erythropoietin.
Which laboratory value is most important for the nurse to monitor to ensure the
medication's effectiveness?
A. Serum creatinine
B. Hemoglobin and hematocrit
C. Serum potassium
D. Blood urea nitrogen
Correct Answer: B. Hemoglobin and hematocrit
Rationale: Erythropoietin stimulates red blood cell production, so monitoring hemoglobin
and hematocrit is essential to assess response and adjust dosing. Creatinine, BUN, and
potassium are important in CKD management but do not directly reflect erythropoietin
efficacy.
Why Wrong:
A - Creatinine reflects kidney function, not the effect of erythropoietin.
C - Potassium levels are important but not a direct indicator of erythropoietin
response.
D - BUN is a marker of kidney function and hydration, not erythropoietin
effectiveness.
Reference: National Kidney Foundation (2026). KDOQI Clinical Practice Guidelines for
Anemia in CKD.
Q4. A patient with hyperthyroidism is started on propylthiouracil (PTU). Which
adverse effect requires immediate discontinuation of the medication?
A. Pruritus and mild rash
B. Sore throat and fever
C. Nausea and vomiting
D. Dizziness and headache
Correct Answer: B. Sore throat and fever
Rationale: Sore throat and fever may indicate agranulocytosis, a life-threatening adverse
effect of PTU. The nurse should immediately stop the drug and obtain a complete blood
count. Minor rash, nausea, and dizziness are less severe and may be managed
symptomatically.
Why Wrong:
A - A mild rash is common and may resolve with antihistamines; it does not require
immediate discontinuation.
