Nursing Elites

1. The nurse is reviewing the laboratory test results of a child with Addison's disease. What would the nurse expect to find?

• A. Hypernatremia
• B. Hyperkalemia
• C. Hyperglycemia
• D. Hypercalcemia

Correct answer: B

Rationale: In Addison's disease, adrenal insufficiency leads to decreased aldosterone production. The decreased aldosterone results in impaired sodium reabsorption and potassium excretion, leading to hyperkalemia. Hypernatremia (Choice A) is unlikely because sodium reabsorption is impaired. Hyperglycemia (Choice C) is not a typical lab finding in Addison's disease. Hypercalcemia (Choice D) is not associated with Addison's disease; rather, it can be seen in conditions like hyperparathyroidism.

2. A child undergoes heart surgery to repair the defects associated with tetralogy of Fallot. What behavior is essential for the nurse to prevent postoperatively?

• A. Crying
• B. Coughing
• C. Straining at stool
• D. Unnecessary movement

Correct answer: C

Rationale: The correct behavior that the nurse needs to prevent postoperatively is straining at stool. Straining at stool should be avoided as it can increase intrathoracic pressure, leading to stress on the surgical site. This stress can potentially compromise the surgical repair and increase the risk of complications. Crying, coughing, and unnecessary movement, although important to monitor postoperatively, do not directly impact the surgical site as significantly as straining at stool does. Therefore, the focus should be on preventing straining at stool to ensure the best postoperative outcome for the child.

3. The nurse is caring for an infant with candidal diaper rash. Which topical agent would the nurse expect the healthcare provider to order?

• A. Corticosteroids.
• B. Antifungals.
• C. Antibiotics.
• D. Retinoids.

Correct answer: B

Rationale: The correct answer is B: Antifungals. Candidal diaper rash is caused by a yeast infection and is best treated with antifungal agents. Corticosteroids (choice A) may worsen fungal infections by suppressing the immune response. Antibiotics (choice C) are used to treat bacterial infections, not fungal infections like candidal diaper rash. Retinoids (choice D) are not typically used to treat candidal diaper rash in infants; they are more commonly used for dermatological conditions like acne.

4. What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?

• A. Mental retardation occurs if PKU is untreated.
• B. Testing for PKU is done immediately after birth.
• C. Treatment for PKU includes lifelong dietary management.
• D. PKU is transmitted by an autosomal recessive gene.

Correct answer: A

Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that, if left untreated with dietary management, can lead to severe mental retardation due to the accumulation of phenylalanine. It is crucial for parents to understand the potential consequences of untreated PKU to emphasize the importance of early and consistent treatment. Choice B is incorrect because testing for PKU is typically done through newborn screening shortly after birth, not immediately. Choice C is incorrect as treatment for PKU primarily involves strict dietary management that restricts phenylalanine intake, not lifelong medications. Choice D is incorrect as PKU is inherited in an autosomal recessive pattern, meaning that both parents must pass on a mutated gene for the disorder to manifest.

5. A 1-year-old child has a congenital cardiac malformation that causes right-to-left shunting of blood through the heart. What clinical finding should the healthcare provider expect?

• A. Proteinuria
• B. Peripheral edema
• C. Elevated hematocrit
• D. Absence of pedal pulses

Correct answer: C

Rationale: In a congenital cardiac malformation causing right-to-left shunting, the nurse should expect an elevated hematocrit. This occurs because the body compensates for decreased oxygenation by producing more red blood cells. Proteinuria (Choice A) is not typically associated with congenital cardiac malformations causing right-to-left shunting. Peripheral edema (Choice B) is more commonly seen in conditions causing left-sided heart failure. Absence of pedal pulses (Choice D) is not a typical finding in congenital cardiac malformations causing right-to-left shunting.
