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: Newborns have a large surface area relative to their body weight, making them more susceptible to heat loss and requiring careful thermoregulation. Choice A is incorrect because renal function is not directly related to thermoregulation. Choice B is incorrect because a flexed posture actually helps reduce heat loss by minimizing the surface area exposed to the environment. Choice D is incorrect because neonates have limited subcutaneous fat, which contributes to their susceptibility to heat loss.

2. What is a primary consideration for complications when planning nursing care for an infant with Meconium aspiration syndrome?

• A. Hypoglycemia
• B. Bowel obstruction
• C. Airway obstruction
• D. Carbon dioxide retention

Correct answer: C

Rationale: The correct answer is C: Airway obstruction. When planning nursing care for an infant with Meconium aspiration syndrome, a primary consideration for complications is the potential of airway obstruction. After the passage of meconium into the amniotic fluid, the infant may inhale or swallow the fluid, leading to meconium aspiration into the lower airways and causing a partial airway obstruction. This can result in respiratory distress and hypoxemia. Hypoglycemia (choice A) is a metabolic condition unrelated to meconium aspiration. Bowel obstruction (choice B) with meconium may indicate other conditions like cystic fibrosis or Hirschsprung disease, not directly related to meconium aspiration syndrome. Carbon dioxide retention (choice D) is not a primary consideration in meconium aspiration syndrome; instead, the focus is on addressing the airway obstruction and potential respiratory compromise.

3. The nurse is preparing an airborne infection isolation room for a patient. Which communicable disease does the patient likely have?

• A. Varicella
• B. Pertussis
• C. Influenza
• D. Scarlet fever

Correct answer: A

Rationale: Varicella (chickenpox) is an airborne infectious disease, requiring isolation to prevent the spread of the virus.

4. The presence of which pair of factors is a good predictor of a fluid deficit of at least 5% in an infant?

• A. Weight loss and decreased heart rate
• B. Capillary refill of less than 2 seconds and no tears
• C. Increased skin elasticity and sunken anterior fontanel
• D. Dry mucous membranes and generally ill appearance

Correct answer: D

Rationale: Dry mucous membranes and an ill appearance are good indicators of dehydration in infants, often correlating with a fluid deficit of at least 5%. Sunken fontanels and poor skin turgor are also indicative but were not options here.

5. Which medication should the nurse expect to administer to a child with an acute sickle cell pain crisis?

• A. Meperidine (Demerol)
• B. Morphine
• C. Acetaminophen (Tylenol)
• D. Ibuprofen (Motrin)

Correct answer: B

Rationale: In the management of acute sickle cell pain crisis in children, morphine is the preferred medication due to its effectiveness in providing pain relief. Meperidine (Demerol) is less commonly used in this scenario because of its potential for neurotoxicity with repeated doses. Acetaminophen (Tylenol) and Ibuprofen (Motrin) are not typically sufficient for managing the severe pain associated with sickle cell crises and are not the first-line treatment options.
