RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 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 2 of 5
The nurse is teaching a client how to use an inhaler device. Which client statement indicates to the nurse that the client understands the instructions?
Correct Answer: C
Rationale: Rinsing the mouth after inhaler use, especially with corticosteroids, prevents oral thrush by removing residual medication. Bedtime-only use, meal timing, or caffeine limits are incorrect and unrelated to proper inhaler technique.
Question 3 of 5
The nurse is caring for an adult client who is taking carbidopa-levodopa for Parkinson's disease. The client is concerned that the medication is not working. Which intervention should the nurse implement first?
Correct Answer: A
Rationale: Clarifying the client’s concern about carbidopa-levodopa’s effectiveness guides targeted assessment and intervention. Meal timing, dyskinesia, or urine color are secondary until the specific issue is understood.
Question 4 of 5
A client is receiving orlistat as part of a weight management program. Which ongoing assessment should be included in the plan of care to determine the effectiveness of the medication?
Correct Answer: A
Rationale: Orlistat inhibits fat absorption, aiding weight loss. Monitoring BMI directly assesses weight changes, indicating the medication’s effectiveness. Calorie counts, depression, or protein levels are less specific to orlistat’s primary goal of weight reduction.
Question 5 of 5
Which action should the nurse implement to assess the effectiveness of amlodipine?
Correct Answer: A
Rationale: Amlodipine, a calcium channel blocker, lowers blood pressure to manage hypertension. Measuring blood pressure directly assesses its effectiveness. Calcium levels, electrolytes, or intake/output are not primary indicators of amlodipine’s therapeutic effect.
