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 client reports having insomnia. Which of the following interventions is appropriate for the nurse to recommend?

• A. Exercise 1 hour before bedtime.
• B. Eat a light carbohydrate snack before bedtime.
• C. Drink a cup of hot cocoa before bedtime.
• D. Take a 30-minute nap daily.

Correct answer: B

Rationale: Eating a light carbohydrate snack before bedtime is a suitable intervention for insomnia because it can help stabilize blood sugar levels and promote sleep. Exercising close to bedtime may actually disrupt sleep patterns due to increased alertness and body temperature. Drinking hot cocoa before bedtime, which contains caffeine, may interfere with falling asleep. Taking a nap during the day can make it harder to fall asleep at night and may worsen insomnia. Therefore, the best recommendation among the choices provided is to eat a light carbohydrate snack before bedtime.

3. The healthcare provider is assessing a client with a diagnosis of asthma. Which assessment finding would be most concerning?

• A. Wheezing
• B. Shortness of breath
• C. Use of accessory muscles
• D. Cough with sputum production

Correct answer: C

Rationale: The most concerning assessment finding in a client with asthma is the use of accessory muscles. This indicates that the client is working harder to breathe, which could signify respiratory distress. Wheezing, choice A, is a common finding in asthma and indicates narrowed airways but may not necessarily imply immediate distress. Shortness of breath, choice B, is also common in asthma but may not be as concerning as the use of accessory muscles. Cough with sputum production, choice D, can occur in asthma exacerbations but may not be as critical as signs of increased work of breathing like the use of accessory muscles.

4. A healthcare professional is planning to perform ear irrigation on an adult client with impacted cerumen. Which of the following should the professional plan to take?

• A. Wearing sterile gloves while performing irrigation
• B. Positioning the client with the affected side down following irrigation
• C. Using cool fluid to irrigate the ear canal
• D. Pulling the pinna downward during irrigation

Correct answer: B

Rationale: Positioning the client with the affected side down following irrigation is crucial as it helps facilitate drainage of the dislodged cerumen and any remaining irrigation solution. This position allows gravity to assist in the removal of the loosened debris. Wearing sterile gloves is a standard precaution in healthcare procedures to prevent infection but is not specific to ear irrigation. Using body-temperature water or a solution at a slightly warmer temperature is recommended to prevent vertigo and discomfort, so using cool fluid is incorrect. Pulling the pinna upward and backward, not downward, straightens the ear canal for adults to facilitate the irrigation process, making choice D incorrect.

5. A home health nurse is discussing the dangers of carbon monoxide poisoning with a client. Which of the following information should the nurse include?

• A. Carbon monoxide does not have a distinct odor.
• B. Water heaters should be inspected every 5 years.
• C. The lungs are not damaged from carbon monoxide inhalation.
• D. Carbon monoxide binds with hemoglobin in the body.

Correct answer: D

Rationale: The correct answer is D: 'Carbon monoxide binds with hemoglobin in the body.' Carbon monoxide is an odorless, colorless gas, so it does not have a distinct odor (Choice A). While regular inspection of appliances like water heaters is important for safety, it is not directly related to carbon monoxide poisoning (Choice B). Carbon monoxide primarily affects the cardiovascular system by binding with hemoglobin, reducing the blood's ability to carry oxygen, rather than causing direct lung damage (Choice C). Understanding how carbon monoxide binds with hemoglobin is crucial in recognizing the mechanism of poisoning and its potential consequences.
