RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 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 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
A client receives a prescription for allopurinol. Which information provided by the client requires additional instruction by the nurse?
Correct Answer: A
Rationale: Doubling a missed allopurinol dose risks toxicity and is incorrect; clients should take it as soon as remembered or skip it if near the next dose. Reducing caffeine/alcohol, taking with food, and hydration are appropriate to manage uric acid and GI effects.
Question 4 of 5
The nurse is reviewing the client's laboratory values. Which serum laboratory value indicates to the nurse that a prescription for atorvastatin is having the desired effect for a client at risk for coronary artery disease?
Correct Answer: D
Rationale: Atorvastatin lowers LDL cholesterol, reducing coronary artery disease risk. Decreased LDL levels indicate effectiveness. HDL, PT, and CK are not primary measures of atorvastatin’s therapeutic effect.
Question 5 of 5
The healthcare provider prescribes propylthiouracil (PTU) and Lugol's solution, a strong iodine solution, for a client with hyperthyroidism. How should the nurse schedule the administration of these medications?
Correct Answer: D
Rationale: Lugol’s solution reduces thyroid hormone production rapidly, preparing the gland for PTU, which inhibits hormone synthesis. Administering iodine one hour before PTU optimizes treatment efficacy. Parenteral dosing, meal timing, or bedtime scheduling are incorrect.
