Extract:
Question 1 of 5
A nurse is calculating the intake of a client during the past 9 hr. The client's intake includes lactated Ringer's IV at 150 mL/hr. cefazolin 2 g IV intermittent bolus in 100 mL of 0.9% sodium chloride. two units of packed RBCs of 275 mL and 250 mL; two IV bolus infusions of 250 mL of 0.9% sodium chloride, famotidine 20 mg IV intermittent bolus in 50 mL of 0.9% sodium chloride. How many mL of intake should the nurse record?
Correct Answer: 2525
Rationale: Calculate: Lactated Ringer's (150 mL/hr × 9 hr = 1350 mL), cefazolin (100 mL), RBCs (275 + 250 = 525 mL), saline boluses (250 × 2 = 500 mL), famotidine (50 mL).
Total = 1350 + 100 + 525 + 500 + 50 = 2525 mL.
Question 2 of 5
A nurse is caring for a client who is exhibiting signs of alcohol withdrawal. Which of the following medications should the nurse plan to administer?
Correct Answer: A
Rationale: Diazepam, a benzodiazepine, is used to manage alcohol withdrawal symptoms. Disulfiram deters alcohol use, while methadone and buprenorphine are for opioid withdrawal.
Question 3 of 5
A nurse is reviewing the medical record of a client who reports taking pseudoephedrine for sinus congestion as needed. The nurse should identify that pseudoephedrine is contraindicated for which of the following client conditions?
Correct Answer: A
Rationale: Pseudoephedrine increases blood pressure, making it contraindicated in hypertension. It is not contraindicated for eczema, diverticulitis, or migraines.
Question 4 of 5
A nurse is reviewing a client's prescription for 1,000 mL of 5% dextrose in water IV to infuse over 8 hr. At 1400, the nurse observes that there is 500 mL of solution remaining in the client's current IV bag. At what time should the nurse administer the next bag of IV solution?
Correct Answer: D
Rationale: Infusion rate: 1000 mL ÷ 8 hr = 125 mL/hr. At 1400, 500 mL remains (4 hr at 125 mL/hr), so the bag finishes at 1800, when the next bag should be administered.
Question 5 of 5
A nurse in a public clinic is planning a health fair for older adult clients in the community. In teaching medication safety, which of the following foods should the nurse advise the clients to avoid when taking their prescriptions?
Correct Answer: D
Rationale: Grapefruit juice interacts with many medications by inhibiting the cytochrome P450 enzyme system, potentially leading to dangerous drug levels. Carbonated beverages, orange juice, and milk have fewer and less severe interactions.
