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. A 16-year-old female student with a history of asthma controlled with both an oral antihistamine and an albuterol (ProAir) 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 crucial information for the nurse to obtain in this scenario is how often the metered-dose inhaler (MDI) is used daily. This information will help assess if the symptoms of insomnia, shakiness, and palpitations are potentially related to overuse of the inhaler, which can cause side effects such as tremors and palpitations. Monitoring the frequency of MDI usage is essential in managing asthma and ensuring appropriate medication administration.

3. When should the surgical correction of hypospadias in a newborn infant typically be done?

• A. Repair should be done by one month to prevent bladder infection.
• B. To form a proper urethra repair, it should be done after sexual maturity.
• C. Repairs typically should be done before the child is potty trained.
• D. Delaying the repair until school age reduces castration fears.

Correct answer: C

Rationale: Surgical repairs for hypospadias are typically recommended to be performed before the child is potty trained. This timing helps in avoiding complications, ensures better outcomes, and makes the surgical process smoother. Early correction also minimizes the psychological impact on the child regarding genital differences and can improve long-term psychological well-being. Choices A, B, and D are incorrect because repairing hypospadias at one month to prevent bladder infection, after sexual maturity to form a proper urethra, or delaying the repair until school age to reduce castration fears are not the standard recommendations. The optimal timing for surgical correction is before the child is potty trained to achieve the best results and psychological outcomes.

4. When screening a 5-year-old for strabismus, what action should the nurse take?

• A. Have the child identify colored patterns on polychromatic cards.
• B. Direct the child through the six cardinal positions of gaze.
• C. Inspect the child for the setting sun sign.
• D. Observe the child for blank, sunken eyes.

Correct answer: B

Rationale: When screening a 5-year-old for strabismus, directing the child through the six cardinal positions of gaze is the most appropriate action. This method helps the nurse to assess eye alignment, which is crucial in identifying any misalignment that may indicate strabismus. Choices A, C, and D are incorrect. Having the child identify colored patterns on polychromatic cards is more related to visual acuity testing rather than strabismus screening. Inspecting the child for the setting sun sign is not a standard method for strabismus screening. Observing the child for blank, sunken eyes is not specific to strabismus assessment.

5. During a follow-up clinical visit, a mother tells the nurse that her 5-month-old son, who had surgical correction for tetralogy of Fallot, has rapid breathing, often takes a long time to eat, and requires frequent rest periods. The infant is not crying while being held, and his growth is in the expected range. Which intervention should the nurse implement?

• A. Stimulate the infant to cry to produce cyanosis
• B. Auscultate the heart and lungs while the infant is held
• C. Evaluate the infant for failure to thrive
• D. Obtain a 12-lead electrocardiogram

Correct answer: B

Rationale: Auscultating the heart and lungs while the infant is held can provide important diagnostic information in assessing the cardiac and respiratory status of the infant who had surgical correction for tetralogy of Fallot. This intervention can help the nurse identify any abnormal heart or lung sounds, which may indicate complications or issues that need further evaluation or intervention.
