Nursing Elites

1. A 9-week-old infant is scheduled for cleft lip repair. Which information is most important for the nurse to convey to the surgeon before transporting the infant to the surgical suite?

• A. Red blood cell count of 2.3 million/mm³
• B. White blood cell count of 10,000/mm³
• C. Weight gain of 2 pounds since birth
• D. Urine specific gravity is 1.011

Correct answer: A

Rationale: The correct answer is A because a low red blood cell count may indicate anemia, which could pose risks during surgery. Anemia can affect oxygen delivery to tissues, impacting wound healing and overall surgical outcomes. The other options, such as white blood cell count, weight gain, and urine specific gravity, are less critical for immediate surgical considerations. White blood cell count is more related to infection risk postoperatively rather than immediate surgical risk. Weight gain reflects good overall growth but does not impact the immediate surgical situation. Urine specific gravity is more indicative of hydration status rather than immediate surgical risk.

2. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt

Correct answer: B

Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.

3. 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.

4. What is the best response for the nurse when a 2-year-old boy begins to cry as the mother starts to leave?

• A. Let me read this book to you.
• B. Two-year-olds usually stop crying the minute the parent leaves.
• C. Now be a big boy. Mommy will be back soon.
• D. Let's wave bye-bye to mommy.

Correct answer: D

Rationale: The best response for the nurse in this situation is to help the child understand that the separation is temporary. Waving bye-bye to mommy can be reassuring to the child and make the separation process easier. It acknowledges the child's feelings while providing a positive and comforting interaction. Choice A may distract the child temporarily but doesn't address the underlying issue of separation anxiety. Choice B is inaccurate as children may continue to cry even after the parent leaves. Choice C diminishes the child's emotions and doesn't offer a supportive approach.

5. A child is recovering from an appendectomy. The parent asks when the child can resume normal activities. What is the best response by the nurse?

• A. The child can resume normal activities as soon as they feel up to it
• B. The child should avoid strenuous activities for at least 2 weeks
• C. The child can resume normal activities after the stitches are removed
• D. The child should avoid all physical activities for the next month

Correct answer: B

Rationale: After an appendectomy, it is important for the child to avoid strenuous activities for at least 2 weeks to allow for proper healing. Resuming normal activities too soon can put unnecessary strain on the healing process and increase the risk of complications.
