Nursing Elites

1. The parents of a newborn with phenylketonuria (PKU) need help and support in adhering to specific dietary restrictions. They ask the nurse, “How long will our child have to be on this diet?” How should the nurse respond?

• A. “We are still not sure; you should discuss this with your health care provider.”
• B. “If your baby does well, foods containing protein can gradually be introduced.”
• C. “Your child needs to be on this diet at least through adolescence and into adulthood.”
• D. “This is a lifelong problem, and it is recommended that dietary restrictions must be continued.”

Correct answer: D

Rationale: The correct answer is D: “This is a lifelong problem, and it is recommended that dietary restrictions must be continued.” Phenylketonuria (PKU) is a metabolic disorder where the body cannot process phenylalanine properly. The diet for PKU must be continued lifelong to prevent cognitive and developmental issues, as phenylalanine buildup can cause irreversible damage. Choice A is incorrect because the nurse should provide information about the lifelong nature of the dietary restrictions for PKU. Choice B is incorrect as it suggests reintroducing protein-containing foods, which is not recommended for individuals with PKU. Choice C is incorrect as it underestimates the duration of the necessary dietary restrictions for PKU.

2. A healthcare professional is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the professional identify as the cause of the polycythemia?

• A. Low tissue oxygen needs
• B. Tissue oxygen needs
• C. Diminished iron level
• D. Hypertrophic cardiac muscle

Correct answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs as the body's response to chronic hypoxia by increasing RBC production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect, the heart's structure causes reduced oxygen levels in the blood. This chronic hypoxia stimulates the bone marrow to produce more red blood cells, leading to an elevated RBC count. Choice A is incorrect as low blood pressure is not directly related to polycythemia in this context. Choice C, diminished iron level, is not the cause of polycythemia in tetralogy of Fallot. Choice D, hypertrophic cardiac muscle, is not the primary cause of the elevated RBC count in this case.

3. An order is written for an isotonic enema for a 2-year-old child. What is the maximum amount of fluid the nurse should administer without a specific order from the health care provider?

• A. 100 to 150 mL
• B. 155 to 250 mL
• C. 255 to 360 mL
• D. 365 to 500 mL

Correct answer: B

Rationale: For a 2-year-old child, the maximum recommended amount of fluid for an isotonic enema is between 155 to 250 mL to prevent overdistension and potential harm. Choice A (100 to 150 mL) is too low and may not be effective in achieving the desired outcome. Choices C (255 to 360 mL) and D (365 to 500 mL) exceed the safe range for a 2-year-old child and can lead to overdistension, electrolyte imbalance, or other complications. Therefore, the correct answer is B.

4. A healthcare professional is teaching a class of new parents about how to position their infants during the first few weeks of life. Which position is safest?

• A. On the back, lying flat
• B. On either side, lying flat
• C. Head slightly elevated on the left side
• D. Head slightly elevated on the right side

Correct answer: A

Rationale: The correct answer is 'On the back, lying flat.' Placing infants on their back to sleep is recommended to reduce the risk of sudden infant death syndrome (SIDS). This position promotes safe sleep practices and helps prevent accidental suffocation. Choices B, C, and D are incorrect as placing infants on their side or with the head slightly elevated may increase the risk of breathing difficulties or other hazards during sleep.

5. After corrective surgery for hypertrophic pyloric stenosis (HPS) is completed, and the infant is returned to the pediatric unit with an IV infusion in place, what is the priority nursing action?

• A. Apply adequate restraints.
• B. Administer a mild sedative.
• C. Assess the IV site for infiltration.
• D. Attach the nasogastric tube to wall suction.

Correct answer: C

Rationale: The priority nursing action after corrective surgery for hypertrophic pyloric stenosis (HPS) is to assess the IV site for infiltration. This is crucial as it ensures proper fluid administration and prevents complications such as phlebitis or infiltration-related tissue damage. Applying restraints (Choice A) would not be appropriate in this situation as it is not related to the immediate post-operative care of an infant with an IV infusion. Administering a mild sedative (Choice B) is not indicated as the primary concern post-surgery is monitoring the IV site and the infant's response to the surgery. Attaching the nasogastric tube to wall suction (Choice D) is not the priority at this time, as assessing the IV site takes precedence to prevent potential complications.
