Question 1 of 5
The healthcare provider prescribes the antibiotic surgical prophylaxis protocol for a client who weighs 90 kg. The protocol is cefazolin 2 grams/100 mL 0.9% normal saline over 1 hour for clients weighing less than 265.5 pounds or cefazolin 3 grams/100 mL 0.9% normal saline over 90 minutes for clients weighing greater than 265.5 pounds. The nurse should program the pump to deliver how many mL/hr?
Correct Answer: 100
Rationale: Client weighs 90 kg = 198 lbs (<265.5 lbs), so protocol is 2 grams/100 mL over 1 hour. Infusion rate = 100 mL / 1 hour = 100 mL/hr.
Question 2 of 5
A client with cystitis receives a prescription for phenazopyridine. Which information should the nurse explain to the client about its therapeutic effect?
Correct Answer: B
Rationale: Phenazopyridine is a urinary analgesic that relieves pain and burning from irritated bladder mucosa. It does not kill bacteria, calm spasms, or require specific timing related to intercourse.
Question 3 of 5
Based on a client's serum digoxin level, the client is diagnosed with digoxin toxicity. Which action should the nurse expect to implement?
Correct Answer: A
Rationale: Checking acid-base and electrolyte values is critical for digoxin toxicity, as imbalances like hypokalemia worsen toxicity. Changing routes, cardioversion, or potassium administration are not immediate without assessment.
Question 4 of 5
A female client who is starting a new prescription for doxycycline hyclate tells the nurse that she takes birth control pills. Which action should the nurse take?
Correct Answer: B
Rationale: Doxycycline reduces birth control pill effectiveness, requiring additional contraception. Timing separation, stopping birth control, or notifying about contraindications are incorrect actions.
Question 5 of 5
A client with iron deficiency anemia is taking ferrous sulfate elixir. Which instruction should the nurse provide this client?
Correct Answer: A
Rationale: Using a straw prevents tooth staining from ferrous sulfate. Undiluted swallowing risks staining, milk reduces absorption due to calcium, and antacids interfere with iron absorption.
