RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 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 2 of 5
A glucagon emergency kit is prescribed for a client with type 1 diabetes mellitus. When should the nurse instruct the client and family that glucagon needs to be administered?
Correct Answer: C
Rationale: Glucagon raises blood glucose in severe hypoglycemia (e.g., unconsciousness), preventing complications. It’s not for hyperglycemia, sick days, or diabetic ketoacidosis, which require insulin and other treatments.
Question 3 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 4 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 5 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.
