Nursing Elites

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

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

Correct answer: C

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

2. 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 in the first trimester of gestation.
• B. At birth, the endocrine glands are not fully functional.
• C. Infants may have difficulty balancing glucose and electrolytes.
• D. A child’s endocrine system plays a vital role in growth and development.

Correct answer: C

Rationale: The correct statement is that infants may have difficulty balancing glucose and electrolytes because their endocrine systems are immature. Newborns have developing endocrine glands that are not yet fully functional, leading to challenges in maintaining glucose and electrolyte balance. Choice A is incorrect as endocrine glands start developing in the first trimester, not the third trimester. Choice B is incorrect as endocrine glands are not fully functional at birth. Choice D is incorrect because while a child’s endocrine system indeed plays a vital role in growth and development, the specific focus of the question is on the challenges infants face due to immature endocrine glands.

3. A parent brings a 2-month-old infant with Down syndrome to the pediatric clinic for a physical and administration of immunizations. Which clinical finding should alert the nurse to perform a further assessment?

• A. Flat occiput
• B. Small, low-set ears
• C. Circumoral cyanosis
• D. Protruding furrowed tongue

Correct answer: C

Rationale: Circumoral cyanosis should alert the nurse to perform a further assessment because it may indicate inadequate oxygenation or circulation, potentially related to cardiac or respiratory issues. Flat occiput (choice A) is a common finding in infants and is not typically concerning. Small, low-set ears (choice B) are common in Down syndrome and not specifically indicative of an acute issue requiring immediate further assessment. Protruding furrowed tongue (choice D) is also commonly seen in infants with Down syndrome and typically does not warrant immediate further assessment unless associated with other concerning signs or symptoms.

4. During a nap, a 3-year-old hospitalized child wets the bed. How should the nurse respond?

• A. Ask the child to help with remaking the bed.
• B. Put clean sheets on the bed over a rubber sheet.
• C. Change the child’s clothes without discussing the incident.
• D. Explain that children should call the nurse when they need to go to the bathroom.

Correct answer: C

Rationale: When a 3-year-old hospitalized child wets the bed during a nap, the nurse should respond by changing the child’s clothes without discussing the incident. This approach helps to maintain the child's dignity, avoid embarrassment, and reduce anxiety related to bedwetting. Asking the child to help with remaking the bed (Choice A) may not be appropriate as it could cause unnecessary distress. Putting clean sheets on the bed over a rubber sheet (Choice B) addresses the aftermath but does not directly address the child's needs. Explaining that children should call the nurse when they need to go to the bathroom (Choice D) may not be effective in this immediate situation of bedwetting during a nap.

5. After a discussion with the healthcare provider, the parents of an infant with patent ductus arteriosus (PDA) ask the nurse to explain once again what PDA is. How should the nurse respond?

• A. The diameter of the aorta is enlarged.
• B. The wall between the right and left ventricles is open.
• C. It is a narrowing of the entrance to the pulmonary artery.
• D. It is a connection between the pulmonary artery and the aorta.

Correct answer: D

Rationale: Patent ductus arteriosus (PDA) is an abnormal connection between the pulmonary artery and the aorta. In a fetus, the ductus arteriosus is a normal connection between these two vessels, allowing blood to bypass the lungs. However, it should close shortly after birth. When it remains open (patent), it leads to PDA. Choices A, B, and C do not accurately describe PDA. Choice A describes an enlarged aorta, choice B describes a ventricular septal defect, and choice C describes pulmonary stenosis, which are different cardiac conditions.
