COMPLETE (140) CURRENT TESTING QUESTIONS AND
CORRECT ANSWERS WITH DETAILED RATIONALES.
PHARM
Prepare effectively for the Pharm HESI Exam with this focused study resource. It
supports review of essential pharmacology concepts, medication classes,
mechanisms of action, adverse effects, safe medication administration, and clinical
considerations. Use the material to reinforce your knowledge, review key topics, and
identify areas that may require additional study. This resource is suited for nursing
students, HESI learners, and candidates preparing for pharmacology-focused HESI
examinations.
MULTIPLE CHOICE.
Section 1: Pharmacokinetics, Pharmacodynamics & Medication
Administration (Questions 1-20)
1. A nurse is preparing to administer a medication to a client. Which of the
following represents the "Six Rights" of medication administration?
A) Right patient, drug, dose, route, time, and documentation
B) Right patient, drug, dose, route, time, and reason
C) Right patient, drug, dose, route, time, and assessment
D) Right patient, drug, dose, route, time, and evaluation
Answer: A
Rationale: The "Six Rights" of medication administration are the right
patient, right drug, right dose, right route, right time, and right
documentation. Some sources also include right to refuse, right
assessment, and right education.
2. A client is prescribed a medication that must be given on an empty
stomach. When should the nurse administer this medication?
A) 30 minutes before meals
B) 1 hour before or 2 hours after meals
C) With food to reduce gastric irritation
D) Immediately after meals
, Page 2 of 45
Answer: B
Rationale: "Empty stomach" typically means 1 hour before or 2 hours
after meals to ensure optimal absorption without food interference.
3. A client is receiving an IV infusion of potassium chloride. Which action
is essential for the nurse to take?
A) Administer the potassium as an IV push
B) Infuse the potassium at a rate of 40 mEq/hour
C) Monitor the IV site for infiltration
D) Mix the potassium with dextrose solution
Answer: C
Rationale: Potassium is irritating to tissues, and infiltration can cause
tissue necrosis. The nurse must monitor the IV site closely. Potassium
should never be given as an IV push and should be infused at a rate no
faster than 10-20 mEq/hour.
4. A nurse is providing education to a client about a new medication.
Which statement by the client indicates a need for further teaching?
A) "I will take my medication at the same time every day."
B) "I will stop taking the medication if I feel better."
C) "I will report any unusual side effects to my provider."
D) "I will keep my medication in its original container."
Answer: B
Rationale: Medications should be taken as prescribed for the full
duration, even if symptoms improve, to prevent recurrence or resistance.
Stopping early is a common cause of treatment failure.
5. The nurse is preparing to administer an IM injection to an adult client.
Which site is preferred for a large-volume IM injection?
A) Dorsogluteal
B) Ventrogluteal
C) Deltoid
D) Vastus lateralis
Answer: B
Rationale: The ventrogluteal site is preferred for large-volume IM
injections in adults because it is free of major nerves and blood vessels
, Page 3 of 45
and has a large muscle mass. The dorsogluteal site is no longer
recommended due to the risk of sciatic nerve injury.
6. A client is prescribed a medication that has a narrow therapeutic index.
What is the priority nursing intervention?
A) Monitor serum drug levels closely
B) Administer the medication with food
C) Double the dose if a dose is missed
D) Discontinue the medication if side effects occur
Answer: A
Rationale: Medications with a narrow therapeutic index (e.g., digoxin,
lithium, warfarin) require close monitoring of serum levels to avoid
toxicity or subtherapeutic effects.
7. A nurse is administering an otic medication to a 2-year-old child. How
should the nurse position the child's ear?
A) Pull the pinna up and back
B) Pull the pinna down and back
C) Pull the pinna forward and down
D) Keep the head upright
Answer: B
Rationale: For children under 3 years of age, the pinna should be pulled
down and back to straighten the ear canal. For older children and adults,
the pinna is pulled up and back.
8. The nurse is preparing to administer a subcutaneous injection of
heparin. Which action is correct?
A) Aspirate before injecting the medication
B) Massage the site after injection
C) Administer the injection in the abdomen
D) Use a 22-gauge needle
Answer: C
Rationale: Heparin is typically administered subcutaneously in the
abdomen. Aspiration is not recommended, the site should not be
massaged (to prevent bruising), and a small-gauge needle (25-27 gauge) is
used.

9. A client is prescribed an antibiotic suspension. What instruction should
the nurse provide to the client?
A) "Shake the bottle well before each dose."
B) "Use a household spoon for measurement."
C) "Mix the medication with juice."
D) "Refrigerate the medication after each use."
Answer: A
Rationale: Liquid suspensions should be shaken well before each dose to
ensure the medication is evenly distributed. An oral syringe or medicine
cup should be used for accurate measurement.
10. The nurse is administering a medication via a nasogastric (NG) tube.
Which action should the nurse take first?
A) Flush the tube with 30 mL of water
B) Verify tube placement
C) Crush the medication
D) Administer the medication
Answer: B
Rationale: Verifying tube placement is the priority before administering
any medication via an NG tube to prevent aspiration.
11. A client is prescribed a transdermal patch. Which instruction should
the nurse include?
A) "Apply the patch to a hairy area for better adhesion."
B) "Rotate the application site to prevent skin irritation."
C) "Cut the patch in half if a lower dose is needed."
D) "Leave the old patch on when applying a new one."
Answer: B
Rationale: Rotating application sites prevents skin irritation and ensures
consistent absorption. Patches should not be cut, and old patches should
be removed before applying new ones.
12. The nurse is preparing to administer eye drops. Which action is
correct?
A) Instill the drop directly onto the cornea
B) Press on the nasolacrimal duct after instillation
