Q1 Question 1 of 75
A 68-year-old client with chronic heart failure is prescribed furosemide 40 mg orally daily. The nurse
reviews the client's current medication list and notes the client also takes digoxin 0.25 mg daily and
potassium supplements. Which action should the nurse prioritize before administering the morning
dose of furosemide?
A. Assess the client's apical pulse for 1 full minute
B. Check the client's serum potassium level
C. Verify the client's daily weight from the previous day
D. Review the client's most recent creatinine clearance
Correct Answer: B
Rationale:
Furosemide is a loop diuretic that causes significant potassium wasting. When combined with digoxin, hypokalemia
increases the risk of digoxin toxicity. Checking the serum potassium level before administration is the priority safety
action. While assessing pulse and weight are important, they do not address the immediate risk of electrolyte imbalance
potentiating digoxin toxicity.
Q2 Question 2 of 75
A nurse is educating a client who has been prescribed a new medication that is highly protein-bound.
The client asks why this matters. Which response by the nurse best explains the clinical significance of
high protein binding?
A. The medication will be metabolized primarily by the kidneys
B. Only the unbound fraction of the drug is pharmacologically active
C. Protein-bound drugs cross the blood-brain barrier more easily
D. High protein binding increases the drug's absorption from the GI tract
Correct Answer: B
Rationale:
When a drug is highly protein-bound, it binds to plasma proteins (primarily albumin) and becomes inactive. Only the free,
unbound fraction can exert pharmacological effects, distribute to tissues, and be metabolized. If protein levels are low
(e.g., in malnutrition or liver disease), more free drug becomes available, increasing the risk of toxicity.

Q3 Question 3 of 75
A 45-year-old client with a history of alcohol use disorder is admitted for surgery and is prescribed
meperidine for postoperative pain. The nurse recognizes that this combination poses which specific
risk?
A. Increased risk of gastrointestinal bleeding
B. Enhanced CNS depression and respiratory compromise
C. Higher incidence of neuroleptic malignant syndrome
D. Development of acute urinary retention
Correct Answer: C
Rationale:
Both meperidine (an opioid) and alcohol are central nervous system depressants. When combined, they produce additive
or synergistic CNS depression, significantly increasing the risk of respiratory depression, sedation, and hypotension. This
combination is generally avoided in clients with active alcohol use due to the life-threatening respiratory compromise risk.
Q4 Question 4 of 75
The nurse is reviewing a medication order for a client with severe renal impairment. The prescriber has
ordered a medication that is primarily excreted unchanged by the kidneys. What is the nurse's primary
concern regarding this order?
A. The medication will have reduced effectiveness in this client
B. The drug may accumulate to toxic levels due to impaired elimination
C. The client will experience increased gastrointestinal side effects
D. The medication will require higher dosing to achieve therapeutic levels
Correct Answer: B
Rationale:
Drugs excreted primarily by the kidneys rely on adequate renal function for elimination. In severe renal impairment, the
drug cannot be cleared efficiently, leading to accumulation in the body and potential toxicity. The nurse should verify
whether the dose has been appropriately adjusted for the client's renal function or if an alternative medication is
indicated.

Q5 Question 5 of 75
A client receiving intravenous vancomycin develops redness and flushing of the face, neck, and upper
torso shortly after the infusion begins. The nurse recognizes this as red man syndrome. Which nursing
intervention is most appropriate to prevent this reaction?
A. Administer diphenhydramine 25 mg orally 30 minutes before the infusion
B. Switch the client to oral vancomycin immediately
C. Premedicate with acetaminophen 650 mg before each dose
D. Slow the infusion rate to no more than 10 mg per minute
Correct Answer: D
Rationale:
Red man syndrome is a histamine-mediated reaction caused by rapid vancomycin infusion. Slowing the infusion rate to
no more than 10 mg per minute (or over at least 60 minutes for standard doses) is the primary prevention strategy. While
antihistamines may be used in some cases, rate reduction is the evidence-based first-line intervention to prevent this
non-IgE mediated reaction.
Q6 Question 6 of 75
A nurse is preparing to administer warfarin 5 mg orally to a client whose INR is 4.2. The therapeutic
range for this client is 2.0 to 3.0. What is the most appropriate nursing action?
A. Administer the dose as ordered and recheck the INR in 24 hours
B. Hold the dose and notify the prescriber immediately
C. Give half the ordered dose and document the rationale
D. Administer the dose with vitamin K to counteract the elevated INR
Correct Answer: B
Rationale:
An INR of 4.2 is above the therapeutic range of 2.0-3.0 and indicates an increased risk of bleeding. The nurse should
hold the warfarin dose and notify the prescriber immediately for further orders, which may include withholding one or
more doses, adjusting future doses, or administering vitamin K if bleeding is present. The nurse should never
independently adjust or counteract anticoagulant therapy.
