Nursing Elites

1. 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.

2. A 10-year-old child is admitted with diabetic ketoacidosis (DKA). Which laboratory value should the practical nurse (PN) anticipate?

• A. Elevated blood glucose.
• B. Decreased serum ketones.
• C. Low urine glucose.
• D. High bicarbonate levels.

Correct answer: A

Rationale: In a case of diabetic ketoacidosis (DKA), the primary feature is elevated blood glucose levels due to insulin deficiency. Additionally, ketones are increased in the blood and urine. Bicarbonate levels are usually low because of the metabolic acidosis that accompanies DKA. Therefore, the practical nurse should anticipate elevated blood glucose levels as a characteristic laboratory finding in a child admitted with DKA. Choice B is incorrect because serum ketones are increased in DKA. Choice C is incorrect because in DKA, urine glucose is typically high due to spillage of glucose into the urine. Choice D is incorrect because bicarbonate levels are usually low in DKA, not high.

3. The heart rate for a 3-year-old with a congenital heart defect has steadily decreased over the last few hours; it is now 76 bpm, whereas the previous reading 4 hours ago was 110 bpm. Which additional finding should be reported immediately to a healthcare provider?

• A. Oxygen saturation of 94%.
• B. Respiratory rate of 25 breaths/minute.
• C. Urine output of 20 mL/hr.
• D. Blood pressure of 70/40.

Correct answer: D

Rationale: A significant drop in heart rate and blood pressure should be reported immediately as it may indicate worsening of the congenital heart defect. A decrease in blood pressure to 70/40 is a critical finding that suggests potential cardiovascular compromise and requires urgent attention to prevent further deterioration. Oxygen saturation, respiratory rate, and urine output are important parameters, but in this scenario, the alarming decrease in blood pressure is a more critical finding that necessitates immediate reporting to the healthcare provider.

4. 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.

5. The mother of a 9-month-old girl provides the practical nurse with information about her daughter's diet. Which statement by the mother may indicate why the infant has been diagnosed with iron-deficiency anemia?

• A. She almost never drinks sugary water.
• B. She has been on whole milk for 7 months.
• C. She likes to chew on bread as a snack.
• D. She doesn't like to eat peaches or pears.

Correct answer: B

Rationale: The correct answer is B. Infants should not be given cow's milk before 1 year of age as it can interfere with iron absorption and lead to anemia. Choice A is incorrect as avoiding sugary water is actually a good practice. Choice C is unrelated to iron-deficiency anemia. Choice D, not liking peaches or pears, is also not directly related to iron-deficiency anemia.
