Q1 Question 1 of 60
A 68-year-old client is admitted with vomiting and diarrhea for 3 days. Vital signs show BP
94/62 mmHg, HR 118 bpm, RR 22/min, and temperature 37.2 C. The nurse notes dry mucous
membranes and poor skin turgor. Which action should the nurse prioritize first?
A. Administer an antiemetic medication as the first priority
B. Initiate an intravenous infusion of 0.9% sodium chloride per protocol and monitor vital signs
C. Insert a nasogastric tube for decompression
D. Request an order for a complete metabolic panel
Correct Answer: B
Rationale:
The client demonstrates hypovolemia with tachycardia and hypotension, indicating a need for immediate fluid
resuscitation. While antiemetics and labs are relevant, restoring circulating volume takes priority to prevent
progression to hypovolemic shock.
Q2 Question 2 of 60
A nurse is caring for a client receiving continuous intravenous fluids at 125 mL/hr. The client
reports sudden shortness of breath and the nurse auscultates crackles bilaterally. Which is
the most appropriate nursing action?
A. Slow the infusion rate without notifying the provider
B. Slow the infusion rate without notifying the provider
C. Elevate the head of the bed to 45 degrees and notify the provider immediately
D. Document the findings and reassess in 30 minutes
Correct Answer: C
Rationale:
Elevating the head of the bed to 45 degrees reduces venous return and improves respiratory effort in fluid
overload, while notifying the provider allows for orders to reduce or stop the infusion. Simply slowing the rate
without provider communication delays definitive treatment.

Q3 Question 3 of 60
A 54-year-old client with heart failure is prescribed furosemide 40 mg IV twice daily. The
nurse reviews the morning laboratory results and notes a serum potassium of 3.1 mEq/L.
Which is the nurse's priority action?
A. Hold the dose without contacting the provider
B. Hold the dose without contacting the provider
C. Administer the dose and request a potassium supplement per protocol
D. Check the client's blood pressure before giving the dose
Correct Answer: C
Rationale:
With a potassium of 3.1 mEq/L, the nurse can administer the prescribed furosemide while simultaneously
requesting a potassium supplement per standing protocol or provider order. This addresses both the need for
diuresis and prevents further potassium depletion.
Q4 Question 4 of 60
A client with diabetic ketoacidosis has arterial blood gas results showing pH 7.28, PaCO2 28
mmHg, HCO3 14 mEq/L, and PaO2 92 mmHg. Which acid-base imbalance is present?
A. Metabolic acidosis with partial respiratory compensation
B. Respiratory acidosis with metabolic compensation
C. Metabolic alkalosis with respiratory compensation
D. Metabolic acidosis with partial respiratory compensation
Correct Answer: D
Rationale:
The low pH indicates acidosis, the low HCO3 confirms a metabolic origin, and the low PaCO2 shows the lungs
are compensating by hyperventilating. Respiratory compensation is partial because the pH remains below
normal.

Q5 Question 5 of 60
A client with chronic kidney disease stage 4 is scheduled for dialysis. The nurse reviews the
pre-dialysis laboratory values and notes a serum sodium of 128 mEq/L. Which dietary
instruction is most appropriate for this client?
A. Increase oral fluid intake to dilute sodium levels
B. Restrict fluid intake to prescribed limits and avoid salt substitutes containing potassium
C. Consume sports drinks to replace electrolytes lost during dialysis
D. Restrict fluid intake to prescribed limits and avoid salt substitutes containing potassium
Correct Answer: D
Rationale:
Hyponatremia in CKD is managed by fluid restriction to prevent further dilution of serum sodium. Salt substitutes
must be avoided because they contain potassium chloride, which is dangerous in renal impairment. Sports drinks
would worsen electrolyte imbalances.
Q6 Question 6 of 60
A nurse is monitoring a client receiving a blood transfusion. Ten minutes after starting the
infusion, the client reports chills and back pain. The nurse notes a temperature of 38.8 C.
Which is the priority nursing action?
A. Slow the transfusion and administer acetaminophen
B. Slow the transfusion and administer acetaminophen as ordered
C. Stop the transfusion, maintain the IV line with normal saline, and notify the blood bank
D. Stop the transfusion, maintain the IV line with normal saline, and notify the blood bank
Correct Answer: C
Rationale:
An acute hemolytic transfusion reaction requires stopping the transfusion immediately while maintaining IV
access with normal saline for potential emergency medications. The blood bank must be notified to investigate
the reaction and prepare for possible further treatment.
