Nursing Elites

1. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed.
• B. Flexed posture favors heat loss.
• C. A large body surface area favors heat loss to the environment.
• D. A thick layer of subcutaneous fat provides excellent insulation.

Correct answer: C

Rationale: Neonates have a large surface area relative to their weight, which makes them prone to heat loss to the environment, leading to thermoregulation issues. The underdeveloped kidney affecting urine concentration (Choice A) is unrelated to the thermal regulation process. While a flexed posture can help retain heat (Choice B), it does not outweigh the impact of the large body surface area in neonates. Although subcutaneous fat (Choice D) provides insulation, in neonates, the large body surface area is more significant in contributing to heat loss than the fat's insulating properties.

2. Which immunization is typically administered at birth?

• A. Hepatitis B
• B. DTaP
• C. MMR
• D. Varicella

Correct answer: A

Rationale: The correct answer is A, Hepatitis B. The Hepatitis B vaccine is usually given at birth to protect against hepatitis B, a virus that can lead to chronic liver disease and liver cancer. This vaccination is crucial for newborns, especially those born to mothers who are carriers of hepatitis B. Choices B, C, and D are incorrect because DTaP (B), MMR (C), and Varicella (D) vaccines are not typically administered at birth. DTaP is given in a series starting at 2 months, MMR is usually given around 12-15 months, and Varicella is given between 12-15 months of age.

3. An infant with hydrocephalus is hospitalized for surgical placement of a ventriculoperitoneal shunt. Postoperative nursing care would include what?

• A. Monitor closely for signs of infection.
• B. Place the child with the operative side of the head up.
• C. Avoid pumping the shunt reservoir to maintain patency.
• D. Avoid maintaining a Trendelenburg position to decrease pressure on the shunt.

Correct answer: A

Rationale: Postoperative nursing care for an infant with hydrocephalus who underwent ventriculoperitoneal shunt placement includes monitoring closely for signs of infection, as infection is the greatest hazard in the postoperative period. Signs of cerebrospinal fluid infection to watch for include elevated temperature, poor feeding, vomiting, decreased responsiveness, and seizure activity. The child should be placed with the operative side of the head up to reduce pressure on the valve. The shunt reservoir should not be pumped to maintain patency, as this can disrupt its function. Maintaining a Trendelenburg position to decrease pressure on the shunt is contraindicated as it can lead to increased intracranial pressure and compromise the shunt's effectiveness.

4. What are signs and symptoms of a possible kidney transplant rejection in a child? (Select all that apply.)

• A. Fever
• B. Hypotension
• C. All are applicable
• D. Swelling and tenderness of graft area

Correct answer: B

Rationale: Signs of kidney transplant rejection include fever, diminished urinary output, and swelling/tenderness in the graft area. These symptoms indicate that the body may be rejecting the transplanted organ, requiring immediate medical attention.

5. In what condition should the nurse be alert for altered fluid requirements in children? (Select all that apply.)

• A. Oliguric renal failure
• B. Increased intracranial pressure
• C. Mechanical ventilation
• D. All above

Correct answer: D

Rationale: Conditions like oliguric renal failure, increased intracranial pressure, and mechanical ventilation significantly alter fluid requirements in children. These conditions either restrict fluid output or require careful fluid management to avoid worsening the condition.
