Nursing Elites

1. A nurse is caring for an infant with intractable vomiting. For what complication is it most important for the nurse to assess?

• A. Acidosis
• B. Alkalosis
• C. Hyperkalemia
• D. Hypernatremia

Correct answer: B

Rationale: When an infant experiences intractable vomiting, it can lead to the loss of stomach acids, resulting in metabolic alkalosis. Alkalosis is characterized by elevated blood pH and can lead to serious complications. Assessing for alkalosis is essential in this scenario to monitor and manage the infant's condition. Choices A, C, and D are incorrect because in this context, the primary concern is the metabolic imbalance caused by excessive vomiting, leading to alkalosis rather than acidosis, hyperkalemia, or hypernatremia.

2. The parents of an infant ask the nurse why their baby is scheduled to receive the intramuscular polio vaccine rather than the oral vaccine. What is the nurse’s best response?

• A. The American Academy of Pediatrics recommends the intramuscular vaccine because it is safer.
• B. The consensus is that either can be used, since both produce the same results and are equally safe.
• C. The oral vaccine is more expensive, so the intramuscular vaccine is preferred unless it is contraindicated.
• D. The U.S. Centers for Disease Control and Prevention recommends the intramuscular vaccine unless the infant or a family member is immunocompromised.

Correct answer: A

Rationale: The American Academy of Pediatrics recommends the intramuscular polio vaccine because it has a better safety profile compared to the oral vaccine. Choice B is incorrect because the AAP specifically recommends the intramuscular vaccine over the oral vaccine. Choice C is incorrect as cost is not the primary reason for preferring the intramuscular vaccine. Choice D is incorrect as the recommendation is based on safety rather than the immunocompromised status of the infant or family members.

3. Which observation made of the exposed abdomen is most indicative of pyloric stenosis?

• A. abdominal rigidity
• B. substernal retraction
• C. palpable olive-like mass
• D. marked distention of lower abdomen

Correct answer: C

Rationale: The correct answer is C: palpable olive-like mass. In pyloric stenosis, a palpable olive-like mass can often be felt in the abdomen due to the hypertrophied pyloric muscle. This mass is a key characteristic finding in infants with pyloric stenosis. Choice A, abdominal rigidity, is more commonly associated with conditions like peritonitis. Choice B, substernal retraction, is not typically seen in pyloric stenosis but can be a sign of respiratory distress. Choice D, marked distention of the lower abdomen, is not specific to pyloric stenosis and can be present in various abdominal conditions.

4. A group of students is reviewing information about the endocrine system in infants and children. The students demonstrate understanding of the information when they state:

• A. Endocrine glands begin developing during gestation.
• B. Endocrine glands are fully functional at birth.
• C. Infants may have difficulty regulating glucose and electrolytes.
• D. A child’s endocrine system plays a significant role in growth and development.

Correct answer: C

Rationale: The correct answer is C. Infants may have difficulty regulating glucose and electrolytes due to their immature endocrine systems. This can lead to issues such as hypoglycemia and electrolyte imbalances. Choice A is incorrect because endocrine glands actually begin developing early in gestation, not just in the third trimester. Choice B is incorrect as endocrine glands are not fully functional at birth; they continue to mature and develop after birth. Choice D is incorrect as a child's endocrine system has a significant impact on growth and development through the secretion of hormones that regulate various processes in the body, but it does not specifically address the difficulty in regulating glucose and electrolytes seen in infants.

5. A 7-year-old child has an altered mental status, high fever, and a generalized rash. You perform your assessment and initiate oxygen therapy. En route to the hospital, you should be most alert for:

• A. vomiting
• B. seizures
• C. combativeness
• D. respiratory distress

Correct answer: B

Rationale: In a pediatric patient presenting with altered mental status, high fever, and a generalized rash, seizures are a significant concern. Febrile seizures can occur in children with high fevers and may lead to further complications. It is crucial to monitor for seizures and be prepared to manage them promptly. Vomiting, combativeness, and respiratory distress are also important considerations in pediatric patients; however, given the clinical presentation described, seizures take priority as they are a common complication in this scenario.
