Nursing Elites

1. A client is being discharged home with oxygen therapy via a nasal cannula. Which of the following instructions should the nurse provide to the client and family?

• A. Wear cotton clothing to avoid static electricity.
• B. Avoid using any electrical appliances.
• C. Keep the oxygen tank away from heat sources.
• D. Use only a specific type of nasal cannula.

Correct answer: A

Rationale: The correct answer is A: Wear cotton clothing to avoid static electricity. When using oxygen therapy, static electricity can pose a hazard as it increases the risk of fire. Cotton clothing helps reduce static electricity buildup. Choice B, avoiding electrical appliances, is overly restrictive and not entirely necessary. Choice C, keeping the oxygen tank away from heat sources, is important to prevent fire hazards but is not directly related to the nasal cannula. Choice D, using only a specific type of nasal cannula, is not a universal guideline and limits flexibility in care.

2. When admitting a 5-month-old who has vomited 9 times in the past 6 hours, what should the healthcare provider observe for signs of which overall imbalance?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Increased serum hemoglobin levels
• D. Decreased serum potassium levels

Correct answer: B

Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.

3. A nurse on a medical-surgical unit is washing her hands prior to assisting with a surgical procedure. Which of the following actions by the nurse demonstrates proper surgical hand-washing techniques?

• A. The nurse washes with her hands held higher than her elbows.
• B. The nurse uses a brush to scrub under her nails.
• C. The nurse washes for at least 30 seconds.
• D. The nurse uses alcohol-based hand rub only.

Correct answer: A

Rationale: Proper surgical hand-washing technique involves keeping the hands higher than the elbows to prevent contamination. Washing with hands held lower than the elbows can lead to potential contamination. Using a brush to scrub under the nails is not recommended as it can cause microabrasions, increasing infection risk. While washing for at least 30 seconds is a good practice for thorough hand hygiene, hand positioning is critical during surgical hand-washing. Using alcohol-based hand rub alone is insufficient for surgical hand-washing as it may not effectively remove dirt, debris, and transient microorganisms.

4. 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.

5. 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.
