RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 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 2 of 5
The healthcare provider prescribes magnesium sulfate 300 mg/hour IV. The IV bag contains magnesium sulfate 4 grams in dextrose 5% in water (D5W) 500 mL. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 37.5
Rationale: Convert 4 grams to 4000 mg. Infusion rate = (300 mg/hr) ÷ (4000 mg/500 mL) = 300 × 500 ÷ 4000 = 37.5 mL/hr. The pump should be set to 37.5 mL/hr.
Question 3 of 5
A client who is taking furosemide reports experiencing leg cramps, a cough, feeling tired, and palpitations. Which action should the nurse take first?
Correct Answer: A
Rationale: Furosemide can cause hypokalemia, leading to palpitations and cramps, risking arrhythmias. Cardiac monitoring first detects potential arrhythmias, prioritizing safety. Intake/output, compresses, or bed elevation are secondary to addressing cardiac risks.
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.
