Nursing Elites

1. What is an important intervention in providing a neutral thermal environment for an LBW infant in an incubator?

• A. Use wool blankets.
• B. Avoid using disposable diapers.
• C. Prevent heat loss.
• D. Closely monitor both incubator and rectal temperatures.

Correct answer: C

Rationale: Preventing heat loss in a low birth weight (LBW) infant is crucial in maintaining a neutral thermal environment. The use of cotton blankets is recommended over wool blankets. Avoiding disposable diapers is not directly related to maintaining a neutral thermal environment. While monitoring temperatures is important, the key intervention is preventing heat loss to ensure the infant's survival.

2. What test is used to screen for carbohydrate malabsorption?

• A. Stool pH
• B. Urine ketones
• C. C urea breath test
• D. ELISA stool assay

Correct answer: A

Rationale: Stool pH testing is used to screen for carbohydrate malabsorption. A low pH indicates the presence of unabsorbed carbohydrates, which are fermented by bacteria, leading to acidic stool.

3. The nurse is caring for a child with acute renal failure. What laboratory findings should the nurse expect to find? (Select all that apply.)

• A. Hyponatremia
• B. Hyperkalemia
• C. All are applicable
• D. Elevated blood urea nitrogen level

Correct answer: C

Rationale: In acute renal failure, laboratory findings typically include hyperkalemia, hyponatremia, and elevated blood urea nitrogen (BUN) levels due to the kidneys' inability to excrete waste and balance electrolytes. Metabolic alkalosis is less common, with metabolic acidosis being more typical.

4. The child is admitted to the hospital unit newly diagnosed with retinoblastoma. Which clinical manifestation does the nurse anticipate upon assessment?

• A. A white reflex
• B. Blue-tinged sclerae
• C. A red reflex
• D. Yellow-tinged sclerae

Correct answer: A

Rationale: The correct answer is A: A white reflex. The 'white reflex' or leukocoria is a common sign of retinoblastoma. It occurs when the light reflects off the tumor in the eye, giving the pupil a white appearance instead of the normal red reflex. Blue-tinged sclerae (choice B) and yellow-tinged sclerae (choice D) are not typical manifestations of retinoblastoma. A red reflex (choice C) is the normal reflection seen in the eye when light is shone on it and is not associated with retinoblastoma.

5. The parents of a newborn with an umbilical hernia ask about treatment options. The nurse's response should be based on which knowledge?

• A. Surgery is recommended as soon as possible.
• B. The defect usually resolves spontaneously by 3 to 5 years of age.
• C. Aggressive treatment is necessary to reduce its high mortality.
• D. Taping the abdomen to flatten the protrusion is not recommended.

Correct answer: B

Rationale: The correct answer is B. Most umbilical hernias in newborns resolve on their own by 3 to 5 years of age without the need for surgical intervention, unless complications arise. Surgery is not typically recommended for umbilical hernias in newborns due to the high rate of spontaneous resolution. Aggressive treatment is not necessary as umbilical hernias are typically benign and not associated with high mortality. Taping the abdomen is not recommended as it can cause skin irritation and does not speed up the resolution of the hernia.
