Nursing Elites

1. A child weighing 20 kg has a new prescription for cefoxitin at 80 mg/kg/day administered intravenously every 6 hours. How much cefoxitin should be administered with each dose?

• A. 400 mg
• B. 200 mg
• C. 1600 mg
• D. 100 mg

Correct answer: A

Rationale: To determine the amount of cefoxitin to be administered with each dose, first, calculate the total daily dose by multiplying the child's weight (20 kg) by the prescribed dose (80 mg/kg/day): 80 mg/kg/day × 20 kg = 1600 mg/day. Since the medication is administered every 6 hours (4 doses/day), divide the total daily dose by the number of doses: 1600 mg / 4 = 400 mg. Therefore, each dose should be 400 mg. Choice B (200 mg) is incorrect because it is half the calculated dose. Choice C (1600 mg) is incorrect as it represents the total daily dose, not the dose per administration. Choice D (100 mg) is incorrect as it is a quarter of the calculated dose.

2. A nurse is reviewing the correct use of a fire extinguisher with a client. Which of the following actions should the nurse direct the client to take first?

• A. Remove the safety pin from the extinguisher.
• B. Aim the extinguisher at the base of the fire.
• C. Squeeze the handle to release the extinguishing agent.
• D. Sweep the extinguisher from side to side.

Correct answer: A

Rationale: The correct first step in using a fire extinguisher is to remove the safety pin. This action enables the extinguisher to be activated and used effectively. Choice B, aiming the extinguisher at the base of the fire, comes after removing the safety pin. Choice C, squeezing the handle to release the extinguishing agent, and choice D, sweeping the extinguisher from side to side, are subsequent steps in using a fire extinguisher and should follow removing the safety pin.

3. The patient has undergone surgery for a broken leg and has a cast in place. What should the nurse do to prevent skin impairment?

• A. Assess surfaces exposed to the edges of the cast for pressure areas.
• B. Keep the patient's blood pressure low to prevent overperfusion of tissue.
• C. Allow turning in bed to prevent complications.
• D. Encourage the patient's dietary intake to maintain hydration.

Correct answer: A

Rationale: To prevent skin impairment in a patient with a cast, the nurse should assess surfaces exposed to the edges of the cast for pressure areas. This is important to prevent pressure ulcers or skin breakdown. Keeping the patient's blood pressure low (Choice B) is not directly related to preventing skin impairment in this scenario. Allowing turning in bed (Choice C) is essential for preventing complications like pressure ulcers and is not contraindicated. Encouraging the patient's dietary intake (Choice D) to maintain hydration is not directly related to preventing skin impairment associated with a cast.

4. A client with chronic obstructive pulmonary disease (COPD) is being discharged with home oxygen therapy. Which statement by the client indicates a need for further teaching?

• A. I will keep my oxygen tank upright at all times.
• B. I will not use petroleum jelly to keep my nose from drying out.
• C. I will not smoke or allow others to smoke around me.
• D. I will call my doctor if I have difficulty breathing.

Correct answer: B

Rationale: The correct answer is B. Petroleum jelly is flammable and should not be used with oxygen therapy due to the risk of fire. The client should avoid using petroleum-based products around oxygen equipment. Choices A, C, and D are all appropriate statements for a client with COPD receiving home oxygen therapy. Keeping the oxygen tank upright ensures proper oxygen flow, avoiding smoking or exposure to smoke helps prevent respiratory aggravation, and knowing to seek medical help promptly for breathing difficulties is essential for managing COPD effectively.

5. A client with a history of hypertension is prescribed a beta-blocker. Which side effect should the nurse monitor for in this client?

• A. Increased appetite
• B. Dry mouth
• C. Nausea and vomiting
• D. Bradycardia

Correct answer: D

Rationale: The correct answer is D: Bradycardia. Beta-blockers are known to decrease heart rate, which can lead to bradycardia. This is a common side effect that nurses should monitor for in clients taking beta-blockers. Choices A, B, and C are incorrect because increased appetite, dry mouth, nausea, and vomiting are not typical side effects associated with beta-blockers. Therefore, the nurse should focus on monitoring for bradycardia in this client.
