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? (Enter number value only. If rounding is required, round to the nearest whole number.) The nurse should program the pump to deliver how many mL/hr?
Correct Answer: 100
Rationale: The client weighs 90 kg (198.45 pounds), which is less than 265.5 pounds, so the protocol is cefazolin 2 grams/100 mL over 1 hour. Infusion rate = 100 mL ÷ 1 hour = 100 mL/hr.
Question 2 of 5
A young adult female client who is planning to become pregnant asks the nurse if she can continue taking isotretinoin for cystic acne. Which information is most important for the nurse to provide this client? Which information is most important for the nurse to provide this client?
Correct Answer: D
Rationale: Isotretinoin is highly teratogenic, posing severe risks of fetal abnormalities. Discontinuing the medication at least one month before conception ensures it is cleared from the body, preventing harm to the fetus.
Question 3 of 5
The nurse is caring for a client with hypertension, gastroesophageal reflux, and osteoarthritis. While performing a bedside assessment the nurse observes the client is alert and oriented, but is exhibiting signs of jaundice. The nurse should notify the healthcare provider about which scheduled medication? Which scheduled medication should the nurse notify the healthcare provider about?
Correct Answer: A
Rationale: Jaundice indicates potential liver dysfunction, and acetaminophen is metabolized by the liver, posing a risk of hepatotoxicity. Notifying the provider ensures evaluation and possible adjustment of acetaminophen to prevent further liver damage.
Question 4 of 5
A client with peptic ulcer disease (PUD) is scheduled to receive doses of pantoprazole IV and sucralfate PO before breakfast at 0730. The client reports experiencing heartburn when the nurse brings the scheduled medications. Which action should the nurse take? Which action should the nurse take?
Correct Answer: D
Rationale: Pantoprazole reduces acid production, and sucralfate forms a protective barrier over ulcers, both most effective when given before meals. Administering both as scheduled addresses heartburn and promotes ulcer healing.
Question 5 of 5
A client with myasthenia gravis receives a new prescription for pyridostigmine. Which information should the nurse obtain prior to administering the medication? Which information should the nurse obtain prior to administering the medication?
Correct Answer: A
Rationale: Pyridostigmine, a cholinesterase inhibitor, is taken orally and can cause gastrointestinal side effects. Ensuring recent oral intake minimizes these effects and optimizes absorption, making it the most critical information to obtain before administration.
