Nursing Elites

1. A child who weighs 25 kg is receiving IV ampicillin at a dose of 300 mg/kg/24 hours in equally divided doses every 4 hours. How many milligrams should the nurse administer to the child for each dose?

• A. 1875 mg
• B. 625 mg
• C. 2000 mg
• D. 1500 mg

Correct answer: A

Rationale: To calculate the correct dose for each administration, you first need to find the total daily dose: 300 mg/kg * 25 kg = 7500 mg/day. Since this total dose is divided into equally divided doses every 4 hours, there are 6 doses in 24 hours. Therefore, 7500 mg ÷ 6 doses = 1250 mg per dose. The nurse should administer 1250 mg every 4 hours, resulting in a total of 1875 mg for each dose in a 24-hour period. Choice A, 1875 mg, is the correct answer. Choice B, 625 mg, is incorrect as it does not consider the total daily dose and the frequency of administration. Choice C, 2000 mg, is incorrect as it is not the calculated dosage based on the given parameters. Choice D, 1500 mg, is also incorrect as it does not reflect the correct dosage calculation for each dose.

2. The mother of a 4-month-old asks the nurse for advice in preventing diaper rash. What suggestion should the nurse provide?

• A. At diaper change generously powder the baby's diaper area with talcum powder to promote dryness.
• B. Wash the diaper area every 2 hours with soap and water to help prevent skin breakdown.
• C. Use a barrier cream, such as zinc oxide, which does not have to be completely removed with each diaper change.
• D. Place a cloth diaper inside the disposable diaper for overnight periods when increased wearing time is likely.

Correct answer: C

Rationale: Using a barrier cream like zinc oxide protects the skin and helps prevent diaper rash.

3. A 3-year-old child is admitted to the hospital with severe dehydration. The healthcare provider prescribes an IV infusion of 0.9% normal saline. The nurse notes that the child’s heart rate is 150 beats per minute, and the blood pressure is 90/50 mm Hg. What should the nurse do first?

• A. Administer the IV fluids as prescribed
• B. Notify the healthcare provider
• C. Check the child’s urine output
• D. Reassess the child’s vital signs in 30 minutes

Correct answer: A

Rationale: In a pediatric patient with severe dehydration and signs of compromised hemodynamics such as tachycardia (heart rate of 150 bpm) and hypotension (blood pressure of 90/50 mm Hg), the priority intervention is to administer IV fluids as prescribed. Immediate fluid resuscitation is essential to restore hydration, improve perfusion, and stabilize the child's vital signs. While it's important to monitor urine output, initiating fluid resuscitation takes precedence in this situation. Notifying the healthcare provider can cause a delay in critical intervention, and waiting to reassess vital signs in 30 minutes can be detrimental in a child with severe dehydration and compromised hemodynamics.

4. The caregiver discovers a 6-month-old infant unresponsive and calls for help. After opening the airway and finding the infant is still not breathing, what action should the caregiver take?

• A. Palpate femoral pulse and check for regularity.
• B. Deliver cycles of 30 chest compressions and 2 breaths.
• C. Give two breaths that make the chest rise.
• D. Feel the carotid pulse and check for adequate breathing.

Correct answer: C

Rationale: Providing two breaths that make the chest rise is the correct action in this situation. This helps to deliver oxygen to the infant's lungs and body, which is crucial in a situation where the infant is not breathing. Chest rise indicates successful ventilation, and it is an essential step in pediatric resuscitation, especially for infants. Choices A, B, and D are incorrect because palpating the femoral pulse, delivering chest compressions, and feeling the carotid pulse are not the initial actions to take when an infant is not breathing. The priority is to provide effective breaths to establish ventilation.

5. A 16-year-old female student with a history of asthma controlled with both an oral antihistamine and an albuterol (Proventil) metered-dose inhaler (MDI) comes to the school nurse. The student complains that she cannot sleep at night, feels shaky, and her heart feels like it is 'beating a mile a minute.' Which information is most important for the nurse to obtain?

• A. When she last took the antihistamine.
• B. When her last asthma attack occurred.
• C. Duration of most asthma attacks.
• D. How often the MDI is used daily.

Correct answer: D

Rationale: The most important information for the nurse to obtain is how often the MDI is used daily. This is crucial to assess if the symptoms of insomnia, shakiness, and rapid heart rate are related to overuse of the inhaler, leading to potential side effects such as systemic effects of beta-2 agonists.
