Nursing Elites

1. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarctation 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 findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.

2. The mother of a one-month-old calls the clinic to report that the back of her infant's head is flat. How should the nurse respond?

• A. Turn the infant on the left side braced against the crib when sleeping.
• B. Prop the infant in a sitting position with a cushion when not sleeping.
• C. Place a small pillow under the infant's head while lying on the back.
• D. Position the infant on the stomach occasionally when awake and active.

Correct answer: D

Rationale: Positioning the infant on the stomach occasionally when awake and active can help prevent flat spots on the head. This position allows for more natural movement and prevents prolonged pressure on one area of the head, reducing the risk of developing a flat spot. Turning the infant on the left side braced against the crib when sleeping (choice A) is not recommended as it does not address the issue of flat spots. Propping the infant in a sitting position with a cushion when not sleeping (choice B) may increase the risk of falls and is not suitable for a one-month-old. Placing a small pillow under the infant's head while lying on the back (choice C) should be avoided due to the risk of suffocation and sudden infant death syndrome (SIDS).

3. A middle school student was recently diagnosed with attention-deficit hyperactivity disorder (ADHD) and is having trouble with his grades. He is referred to the school nurse by the teacher because he continues to have learning problems. Which action should the school nurse take?

• A. Ask the parents to have the child seen by a clinical psychologist
• B. Ask the parents to become involved in helping the child with his homework
• C. Refer the child to the school counselor for educational testing
• D. Seek the advice of the school principal regarding the child's learning needs

Correct answer: C

Rationale: Referring the child to the school counselor for educational testing is the most appropriate action in this scenario. This step can help identify the specific learning needs of the student and determine the appropriate interventions required to support his academic success. Option A is not the immediate action needed but may be considered in the future. Option B focuses on homework assistance, which may not address the underlying learning problems. Option D involves consulting the school principal, which is not the primary role in addressing the student's learning needs.

4. 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.

5. What information should be reinforced with the parents of a school-aged child about Reye's syndrome?

• A. Vaccinate your child before the age of 7 against Reye's syndrome.
• B. Keep the child at home for 2 days after the symptoms appear.
• C. Avoid giving any medication containing aspirin during a viral illness.
• D. Do not provide any citrus juices during a bacterial or viral illness.

Correct answer: C

Rationale: The correct answer is C: 'Avoid giving any medication containing aspirin during a viral illness.' It is crucial to advise parents to avoid giving any medication containing aspirin during a viral illness to prevent Reye's syndrome. Reye's syndrome is a rare but serious condition linked to the use of aspirin during viral illnesses in children and teenagers. Choices A, B, and D are incorrect because vaccinating against Reye's syndrome is not applicable as there is no specific vaccine for it, keeping the child at home for 2 days after symptoms appear is not a preventive measure for Reye's syndrome, and avoiding citrus juices is not directly related to the prevention of Reye's syndrome.
