Nursing Elites

1. When describing urticaria, what would an instructor include?

• A. It is a type IV hypersensitivity reaction.
• B. Histamine release leads to vasodilation.
• C. Wheals appear first followed by erythema.
• D. The nonpruritic rash blanches with pressure.

Correct answer: B

Rationale: The correct answer is B. Urticaria is a type I hypersensitivity reaction where histamine release leads to vasodilation and the formation of characteristic wheals. Choice A is incorrect as urticaria is associated with type I hypersensitivity, not type IV. Choice C is incorrect because in urticaria, erythema typically appears before the development of wheals. Choice D is incorrect as urticaria is typically pruritic and does not blanch with pressure.

2. A healthcare provider is assessing a child with suspected rheumatic fever. What clinical manifestation is the provider likely to observe?

• A. Jaundice
• B. Peeling skin on the hands and feet
• C. High fever
• D. Severe joint pain

Correct answer: D

Rationale: Severe joint pain is a classic symptom of rheumatic fever, resulting from inflammation of the joints. Rheumatic fever primarily affects the joints, heart, skin, and the central nervous system. Jaundice (Choice A) is not typically associated with rheumatic fever. Peeling skin on the hands and feet (Choice B) is more characteristic of conditions like Kawasaki disease. While high fever (Choice C) can be present in rheumatic fever, it is not as specific or characteristic as severe joint pain.

3. 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.

4. An additional defect is associated with exstrophy of the bladder. For what anomaly should the nurse assess the infant?

• A. Imperforate anus
• B. Absence of one kidney
• C. Congenital heart disease
• D. Pubic bone malformation

Correct answer: D

Rationale: The correct answer is D, pubic bone malformation. Exstrophy of the bladder is commonly associated with pubic bone malformation because the condition involves a defect in the pelvic region. Choices A, B, and C are incorrect. Imperforate anus, absence of one kidney, and congenital heart disease are not typically associated with exstrophy of the bladder.

5. When evaluating the laboratory report of a 1-year-old infant’s hematocrit, a healthcare provider compares it with the expected hematocrit range for this age group. What is the hematocrit of a healthy 12-month-old infant?

• A. 19% to 32%
• B. 29% to 41%
• C. 37% to 47%
• D. 42% to 69%

Correct answer: C

Rationale: The correct hematocrit range for a healthy 12-month-old infant is between 37% to 47%. At this age, this range reflects the normal blood volume and red blood cell (RBC) levels in infants. Choice A (19% to 32%) is too low for a healthy hematocrit level in a 12-month-old. Choice B (29% to 41%) is also below the typical range for a 12-month-old. Choice D (42% to 69%) includes an upper limit that is higher than expected for a healthy infant, making it an incorrect option.
