Nursing Elites

1. Physiologically, the child compensates for fluid volume losses by which mechanism?

• A. Inhibition of aldosterone secretion
• B. Hemoconcentration to reduce cardiac workload
• C. Fluid shift from interstitial space to intravascular space
• D. Vasodilation of peripheral arterioles to increase perfusion

Correct answer: C

Rationale: In response to dehydration, the body compensates by shifting fluids from the interstitial spaces to the intravascular space to maintain blood pressure and perfusion to vital organs. Hemoconcentration and vasoconstriction are other compensatory mechanisms but are less immediate.

2. The nurse is preparing to administer a prescribed, as-needed antiemetic drug for a child diagnosed with cancer. Which action by the nurse is most appropriate?

• A. Administering the drug only if the child is nauseated.
• B. Administering the drug prophylactically before the next dose of chemotherapy.
• C. Administering the drug after the next dose of chemotherapy.
• D. Administering the drug only if the child is experiencing diarrhea.

Correct answer: B

Rationale: Administering the antiemetic prophylactically before the next dose of chemotherapy is the most appropriate action. This approach helps prevent nausea and vomiting associated with chemotherapy. Waiting until the child is already nauseated, as stated in option A, is less effective as it is reactive rather than proactive. Administering the drug after chemotherapy, as in option C, may not be as beneficial in preventing chemotherapy-induced nausea and vomiting. Option D, administering the drug only if the child is experiencing diarrhea, is not relevant to the prevention of chemotherapy-induced nausea.

3. Which factor is most likely to cause a "brittle" diabetic state in a child with type 1 diabetes?

• A. Noncompliance with diet
• B. Insulin resistance
• C. Frequent infections
• D. Hypothyroidism

Correct answer: C

Rationale: Frequent infections can destabilize blood sugar levels, leading to a "brittle" diabetic state in children with type 1 diabetes. Infections increase metabolic demands and can result in significant blood glucose fluctuations, requiring careful monitoring and adjustment of insulin therapy. Noncompliance with diet may affect blood sugar control but is not the primary cause of a "brittle" state. Insulin resistance is more common in type 2 diabetes rather than type 1. Hypothyroidism can impact metabolism but is not directly linked to the development of a "brittle" diabetic state in type 1 diabetes.

4. What diet is most appropriate for the child with chronic renal failure (CRF)?

• A. Low in protein
• B. Low in vitamin D
• C. Low in phosphorus
• D. Supplemented with vitamins A, E, and K

Correct answer: C

Rationale: A low-phosphorus diet is important in managing chronic renal failure to prevent hyperphosphatemia and its associated complications, such as bone disease. Protein intake should be controlled but not necessarily low, and vitamin D supplementation is often required, not reduced.

5. The nurse is caring for a child with Meckel diverticulum. What type of stool does the nurse expect to observe?

• A. Steatorrhea
• B. Clay-colored
• C. Currant jelly-like
• D. Loose stools with undigested food

Correct answer: C

Rationale: Corrected Rationale: Currant jelly-like stools, which contain blood and mucus, are characteristic of Meckel diverticulum. This symptom occurs due to the bleeding from the ectopic gastric mucosa present in the diverticulum. Steatorrhea (choice A) is not typically associated with Meckel diverticulum. Clay-colored stools (choice B) are seen in conditions affecting the biliary system. Loose stools with undigested food (choice D) may indicate malabsorption issues, but it is not specifically linked to Meckel diverticulum.
