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. The client with congestive heart failure (CHF) is receiving furosemide (Lasix). Which laboratory value should the healthcare provider monitor closely?

• A. Potassium
• B. Sodium
• C. Calcium
• D. Magnesium

Correct answer: A

Rationale: Correct! When a client is taking furosemide (Lasix), monitoring potassium levels is crucial due to the potential for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Low potassium levels can predispose the client to cardiac dysrhythmias. Sodium, calcium, and magnesium levels are not typically affected by furosemide to the same extent as potassium, making them less critical to monitor in this scenario.

3. A client returning from the surgical suite following a vaginal hysterectomy is awake and asking for something to drink. Her post-op diet prescription reads: 'clear liquids, advance diet as tolerated.' Which of the following is appropriate for the nurse to tell the patient?

• A. ''I am going to listen to your abdomen.''
• B. ''You need to wait until the surgeon evaluates your condition.''
• C. ''You can have clear liquids, but let me check with the surgeon first.''
• D. ''It is best to start with small sips of clear liquids and observe how you feel.''

Correct answer: A

Rationale: The correct answer is A: ''I am going to listen to your abdomen.'' Listening to the abdomen helps assess bowel sounds and ensure that the client’s gastrointestinal system is ready for oral intake. Choice B is incorrect because the client does not necessarily need to wait for the surgeon to evaluate before starting with clear liquids. Choice C is incorrect because unless there are specific contraindications, clear liquids are usually allowed after surgery. Choice D is incorrect as it does not address the immediate assessment needed before initiating oral intake post-operatively.

4. An elderly male client who suffered a cerebral vascular accident is receiving tube feedings via a gastrostomy tube. The LPN knows that the best position for this client during administration of the feedings is

• A. prone.
• B. Fowler's.
• C. Sims'.
• D. supine.

Correct answer: B

Rationale: Fowler's position is the optimal position for a client receiving tube feedings via a gastrostomy tube because it reduces the risk of aspiration. In Fowler's position, the client is sitting up at a 45- to 60-degree angle, which helps prevent the formula from flowing back into the esophagus and causing aspiration pneumonia. Choice A, prone position (lying face down), would not be suitable for administering tube feedings as it increases the risk of aspiration. Sims' position (lying on the left side with the right knee flexed) and supine position (lying flat on the back) are also not ideal for administering tube feedings as they do not provide the same level of protection against aspiration as Fowler's position does.

5. When teaching the guardian of a 12-year-old male client about manifestations of puberty, which of the following physical changes typically occurs first?

• A. Appearance of downy hair on the upper lip
• B. Hair growth in the axillae
• C. Enlargement of the testes and scrotum
• D. Deepening of the voice

Correct answer: C

Rationale: During puberty in males, the first physical change that typically occurs is the enlargement of the testes and scrotum. This change is due to increased production of testosterone, which stimulates growth and development of the genital organs. The appearance of downy hair on the upper lip (Choice A) and hair growth in the axillae (Choice B) usually follow the enlargement of the testes and scrotum. Deepening of the voice (Choice D) is a later stage change that occurs during puberty as the larynx (voice box) grows and the vocal cords lengthen and thicken.
