QUESTION 1: PHARMACOLOGY (ANTICOAGULANTS)
A nurse is reviewing the laboratory results for a client who is receiving a continuous
intravenous heparin infusion for a pulmonary embolism. The client's activated partial
thromboplastin time (aPTT) is 115 seconds. Which action should the nurse implement first?
A) Increase the heparin infusion rate by 100 units/hour per protocol.
B) Stop the heparin infusion immediately and prepare protamine sulfate.
C) Obtain a blood sample for an immediate prothrombin time (PT) and INR.
D) Document the finding as therapeutic and continue to monitor the client.
Correct Answer: B
HESI Category: Pharmacology and Parenteral Therapies
Next-Gen NCJMM Rationale:
Why it's correct: A normal aPTT is 30–40 seconds, and a therapeutic target for
heparin is 1.5–2.5 times the normal limit (roughly 60–80 seconds). An aPTT of 115
seconds is critically high, putting the client at extreme risk for spontaneous
hemorrhage. The infusion must be stopped immediately, and the antidote
(protamine sulfate) should be ready.
Why others are incorrect: Increasing the rate (Option A) or continuing the infusion
(Option D) will worsen the toxic levels. PT/INR (Option C) is used to monitor warfarin
therapy, not heparin.
Test-Taking Tip: Pair Heparin with aPTT and its antidote Protamine Sulfate.
Remember: Heparin has H (and aPTT has two T's that look like an H).
QUESTION 2: PHARMACOLOGY (CARDIAC GLYCOSIDES)
A nurse is preparing to administer an oral dose of digoxin 0.125 mg to a client with chronic
heart failure. Which assessment must the nurse perform immediately before administering
this medication?
A) Measure the client's blood pressure in both arms.
B) Assess the client's apical pulse rate for one full minute.
C) Review the client's morning serum sodium level.
D) Calculate the client's total fluid intake for the shift.

Correct Answer: B
HESI Category: Pharmacology and Parenteral Therapies
Next-Gen NCJMM Rationale:
Why it's correct: Digoxin is a negative chronotrope that slows the heart rate. The
nurse must count the apical pulse for 60 seconds. The medication must be held, and
the provider notified, if the apical pulse is <60 bpm in an adult, <70 bpm in a child, or
<90 bpm in an infant.
Why others are incorrect: Blood pressure (Option A) and sodium (Option C) are not
primary parameters for holding digoxin. While potassium levels matter (hypokalemia
increases digoxin toxicity risk), sodium does not.
Test-Taking Tip: Digoxin equals Apical Pulse. Always count for a full minute, never a
partial count multiplied.
QUESTION 3: PHARMACOLOGY (PSYCHOTROPIC MEDICATIONS)
A client diagnosed with bipolar disorder is prescribed lithium carbonate. The nurse is
providing dietary teaching to ensure medication safety. Which dietary instruction is essential
for this client?
A) Maintain a consistent intake of dietary sodium and fluids.
B) Completely eliminate all salt from your diet to prevent fluid retention.
C) Restrict fluid intake to less than 1,000 mL per day.
D) Increase intake of green leafy vegetables high in vitamin K.
Correct Answer: A
HESI Category: Pharmacology and Parenteral Therapies
Next-Gen NCJMM Rationale:
Why it's correct: Lithium is a salt that is cleared by the kidneys. It shares a delicate
balance with sodium. If sodium levels drop (due to a low-salt diet or dehydration),
the kidneys will reabsorb lithium instead of sodium, leading to lithium toxicity.
Why others are incorrect: Eliminating salt (Option B) or restricting fluids (Option C)
directly triggers lithium toxicity. Vitamin K (Option D) affects warfarin, not lithium.
Test-Taking Tip: Lithium acts like sodium in the body. If Sodium goes down, Lithium
levels go up into the toxic range. Keep both fluid and salt intake stable.

QUESTION 4: PHARMACOLOGY (ANTIMICROBIALS)
A client is receiving an intravenous infusion of vancomycin for a severe MRSA infection.
Twenty minutes into the infusion, the client develops intense flushing, a red rash across the
face, neck, and upper torso, and reports itching. What is the nurse's priority action?
A) Stop the infusion immediately and prepare to administer epinephrine.
B) Slow the rate of the vancomycin infusion and notify the provider.
C) Administer a prescribed dose of intravenous furosemide.
D) Document the finding as a normal, self-limiting allergic response.
Correct Answer: B
HESI Category: Pharmacology and Parenteral Therapies
Next-Gen NCJMM Rationale:
Why it's correct: The client is experiencing "Red Man Syndrome" (or Vancomycin
Flushing Syndrome), which is a rate-dependent histamine release reaction, not a true
IgE-mediated anaphylactic allergy. The correct action is to slow the infusion rate
down.
Why others are incorrect: Stopping the drug and giving epinephrine (Option A) is
reserved for true anaphylaxis (wheezing, laryngeal edema, hypotension). This
flushing reaction can be managed simply by stretching the delivery time over 60–120
minutes.
Test-Taking Tip: Red Man Syndrome is caused by running vancomycin too fast. Do not
confuse it with a true allergic reaction unless there is airway involvement or shock.
QUESTION 5: PHARMACOLOGY (RESPIRATORY AGENTS)
A nurse is providing discharge instructions to a client with asthma who is prescribed an
albuterol metered-dose inhaler (MDI) and a beclomethasone MDI. Which instruction
regarding the sequence of use is accurate?
A) Inhale the beclomethasone first, wait 5 minutes, then use the albuterol.
B) Inhale the albuterol first, wait 5 minutes, then use the beclomethasone.
C) Mix both medications in a single spacer device and inhale them together.
D) Use the beclomethasone only in the morning and albuterol only at bedtime.
