RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 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 2 of 5
A client with benign prostatic hyperplasia receives a new prescription of tamsulosin. Which intervention should the nurse perform to monitor for an adverse reaction?
Correct Answer: B
Rationale: Tamsulosin, an alpha-1 blocker, can cause orthostatic hypotension, risking dizziness or fainting. Monitoring blood pressure detects this adverse reaction. Urine output, weights, or bladder scans assess BPH symptoms, not tamsulosin’s side effects.
Question 3 of 5
A male client receives a scopolamine transdermal patch 2 hours before surgery. Four hours after surgery, the client tells the nurse that he is experiencing pain and asks why the patch is not working. Which action should the nurse take?
Correct Answer: A
Rationale: Scopolamine prevents postoperative nausea, not pain. Explaining its purpose clarifies the client’s misunderstanding. New patches, expired effects, or placement checks do not address the pain, which requires separate analgesia.
Question 4 of 5
The nurse is caring for a client who takes methotrexate for rheumatoid arthritis and receives a prescription for adalimumab. Which instructions should the nurse provide the client?
Correct Answer: D
Rationale: Adalimumab, an immunosuppressant, increases infection risk. Avoiding crowds and sick individuals minimizes exposure, protecting the client’s compromised immune system. Chest x-rays, vaccinations, or eye exams are not specifically required for adalimumab initiation.
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.
