RN HESI Pharmacology Exam 3 Questions
Extract:
Question 1 of 5
A client receives a prescription for ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (D5W) 200 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter numerical value only.)
Correct Answer: 200
Rationale: Infusion rate = 200 mL ÷ 1 hour = 200 mL/hr. The pump should be set to deliver 200 mL/hr to infuse the entire dose over one hour.
Question 2 of 5
A client has a prescription for heparin 1,000 units IV STAT. Several pre-filled syringes of low molecular weight heparin are available in the client's medication drawer. Which action should the nurse implement?
Correct Answer: A
Rationale: Standard heparin (IV) and low molecular weight heparin (LMWH, subcutaneous) are not interchangeable. Requesting standard heparin from the pharmacy ensures the correct medication and route, preventing dosing errors or inefficacy.
Question 3 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 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 with nasal congestion receives a prescription for phenylephrine 10 mg PO every 4 hours. Which client condition should the nurse report to the healthcare provider before administering the medication?
Correct Answer: A
Rationale: Phenylephrine, a vasoconstrictor, can elevate blood pressure, exacerbating hypertension and risking complications. Reporting this condition ensures safe use or alternative treatments. Bronchitis, edema, or diarrhea are less critical contraindications.
