RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 of 5
A client with chronic lower back pain has been taking ibuprofen PO twice a day for several months. Which assessment is most important for the nurse to complete?
Correct Answer: A
Rationale: Long-term ibuprofen use risks gastrointestinal bleeding or ulcers. Assessing for abdominal pain detects these serious side effects. Pulse volume, pain levels, or sleep patterns are less critical to NSAID-related complications.
Question 2 of 5
The nurse is caring for a client receiving a prescription for sucralfate to treat a peptic ulcer. Which instruction should the nurse provide during discharge education?
Correct Answer: C
Rationale: Sucralfate adheres to ulcer sites best on an empty stomach, taken 1 hour before meals, maximizing its protective effect. Missing a dose should not prompt doubling, and scheduling with meals or bedtime reduces efficacy due to food interference.
Question 3 of 5
A client with a fungal infection of the toenail reports to the nurse that the client has been applying an over-the-counter (OTC) triple antibiotic ointment to the infection daily for two weeks without any improvement. Which action should the nurse take?
Correct Answer: A
Rationale: OTC triple antibiotic ointment is ineffective for fungal infections. Oral terbinafine, a prescription antifungal, effectively treats toenail fungus by penetrating the nail. Increasing ointment frequency or reassuring about duration without changing treatment is inappropriate.
Question 4 of 5
A client with anemia secondary to chronic kidney disease (CKD) started a prescription for epoetin alfa two months ago. Which client finding best indicates that the medication is effective? Reference Range: Hemoglobin (Hgb) [14 to 18 g/dL (8.7 to 11.2 mmol/L)]
Correct Answer: C
Rationale: Epoetin alfa stimulates red blood cell production, directly increasing hemoglobin levels. A rise to 12 g/dL, though below the male reference range, objectively indicates effectiveness in treating anemia. Iron therapy tolerance, subjective energy improvements, or dietary changes are less direct measures of epoetin’s impact.
Question 5 of 5
A client who is taking an oral contraceptive receives a new prescription for erythromycin. Which instruction should the nurse provide to the client?
Correct Answer: C
Rationale: Erythromycin may reduce oral contraceptive efficacy by altering metabolism. Using additional contraception (e.g., condoms) prevents unintended pregnancy. Stopping the contraceptive, spacing doses, or avoiding sunlight are not necessary.
