Question 1 of 5

The nurse is planning the home care of a client who is receiving a mydriatic medication. Which environment is best for this client?

Correct Answer: A

Rationale: Mydriatics dilate pupils, causing photophobia. A dimly lit room reduces discomfort from light sensitivity. Warm temperatures, humid air, or quiet environments do not address this primary issue.

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?

A. Monitor blood pressure. B. Assess urine output. C. Obtain daily weights. D. Perform a bladder scan.

Correct Answer: A

Rationale: Tamsulosin, an alpha-blocker, can cause orthostatic hypotension. 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 client is receiving metronidazole for Clostridium difficile pseudomembranous colitis. Which information should the nurse include in this client's medication teaching plan?

A. Keep medication refrigerated. B. Drink a liter of water daily. C. Take one hour after eating. D. Avoid the use of alcohol.

Correct Answer: D

Rationale: Metronidazole with alcohol causes a disulfiram-like reaction (flushing, nausea). Avoiding alcohol during and 48 hours post-treatment is critical. Refrigeration, specific water intake, or post-meal dosing are not required.

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?

A. Undergo annual eye examinations. B. Have a chest x-ray prior to your first dose. C. Avoid crowds and people who are sick. D. Obtain routine vaccinations as scheduled.

Correct Answer: C

Rationale: Adalimumab’s immunosuppression increases infection risk. Avoiding crowds and sick individuals minimizes exposure. Eye exams are more relevant for methotrexate, chest x-rays are not routine, and live vaccines may be contraindicated.

Question 5 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.)

Your Answer:

Correct Answer: 200

Rationale: Infusion rate = 200 mL ÷ 1 hour = 200 mL/hr. The pump should deliver 200 mL/hr to infuse the entire dose over one hour.
