Nursing Elites

1. 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.

2. A 6-year-old child with asthma is admitted to the hospital with an acute exacerbation. What is the priority nursing intervention?

• A. Administering a bronchodilator
• B. Administering an antihistamine
• C. Administering a corticosteroid
• D. Administering oxygen

Correct answer: A

Rationale: Administering a bronchodilator is the priority intervention for a child experiencing an acute asthma exacerbation. Bronchodilators help to dilate the airways, making breathing easier and relieving acute symptoms of asthma. Antihistamines are not the first-line treatment for asthma exacerbations; they are more commonly used for allergic reactions. Corticosteroids are beneficial in reducing inflammation in asthma but are usually administered after bronchodilators to provide long-term control. Oxygen therapy may be necessary in severe cases of asthma exacerbation, but bronchodilators take precedence in improving airway patency and respiratory distress.

3. The nurse is assessing an infant and notes that the infant's urine has a mousy or musty odor. What would the nurse suspect?

• A. Maple syrup urine disease
• B. Tyrosinemia
• C. Phenylketonuria
• D. Trimethylaminuria

Correct answer: C

Rationale: The correct answer is C: Phenylketonuria (PKU). PKU is suggested by a mousy or musty odor of the urine, which is caused by the inability to metabolize phenylalanine. Choice A, Maple syrup urine disease, is characterized by a sweet-smelling urine. Choice B, Tyrosinemia, typically presents with cabbage-like odor in the urine. Choice D, Trimethylaminuria, is associated with a fishy odor in the urine, breath, and sweat.

4. In planning care for a 7-year-old boy with diabetes insipidus, what is the priority nursing diagnosis?

• A. Deficient fluid volume related to dehydration
• B. Excess fluid volume related to edema
• C. Deficient knowledge related to fluid intake regimen
• D. Imbalanced nutrition, more than body requirements related to excess weight

Correct answer: A

Rationale: The priority nursing diagnosis for a 7-year-old boy with diabetes insipidus is deficient fluid volume related to dehydration. Diabetes insipidus leads to excessive urination and fluid loss, which can result in dehydration. This diagnosis should take precedence as restoring fluid balance is crucial in managing this condition. Choices B, C, and D are less of a priority in this case. Excess fluid volume related to edema is not typically associated with diabetes insipidus. Deficient knowledge about fluid intake and imbalanced nutrition related to excess weight may be important but addressing the dehydration and fluid volume deficit is the most critical aspect in the immediate care of a child with diabetes insipidus.

5. A parent tells the nurse, “My 9-month-old baby no longer has the same strong grasp that was present at birth and no longer acts startled by loud noises.” How should the nurse explain these changes in behavior?

• A. “I will check these responses before deciding how to proceed.”
• B. “Failure of these responses may be related to a developmental delay.”
• C. “Additional sensory stimulation is needed to aid in the return of these responses.”
• D. “These responses are replaced by voluntary activity at about five months of age.”

Correct answer: D

Rationale: The correct answer is D: “These responses are replaced by voluntary activity at about five months of age.” The grasp reflex and startle reflex (Moro reflex) are normal in newborns but typically disappear as the infant's nervous system matures and voluntary control develops. Choice A is incorrect because checking the responses before deciding a course of action does not address the developmental milestone related to the reflexes. Choice B is incorrect as it jumps to a conclusion of developmental delay without considering the normal developmental process. Choice C is incorrect as additional sensory stimulation is not necessary for the return of these reflexes, as they are expected to naturally diminish as part of normal development.
