Nursing Elites

1. The nurse is caring for a 15-year-old boy who has sustained burn injuries. The nurse observes the burn developing a purplish color with discharge and a foul odor. The nurse suspects which infection?

• A. Burn wound cellulitis.
• B. Invasive burn cellulitis.
• C. Burn impetigo.
• D. Staphylococcal scalded skin syndrome.

Correct answer: B

Rationale: The correct answer is B: Invasive burn cellulitis. Invasive burn cellulitis presents with the burn developing a dark brown, black, or purplish color with discharge and a foul odor. Burn wound cellulitis (choice A) typically involves redness, warmth, and swelling around the burn site. Burn impetigo (choice C) is a superficial infection characterized by honey-colored crusting. Staphylococcal scalded skin syndrome (choice D) is a condition caused by exotoxins from Staphylococcus aureus, leading to widespread skin peeling.

2. A group of students is reviewing the components of the endocrine system. The students demonstrate understanding of the review when they identify what as the primary function of this system?

• A. Regulation of water balance
• B. Hormonal secretion
• C. Cellular metabolism
• D. Growth stimulation

Correct answer: B

Rationale: The primary function of the endocrine system is hormonal secretion. This system is responsible for producing and releasing hormones that regulate various bodily functions such as growth, metabolism, and mood. Choice A, regulation of water balance, is more related to the functions of the renal system rather than the endocrine system. Choice C, cellular metabolism, is a general cellular process that involves various systems, not specific to the endocrine system. Choice D, growth stimulation, though hormones can influence growth, it is not the primary function of the endocrine system. Therefore, the correct answer is B.

3. What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?

• A. Mental retardation occurs if PKU is untreated.
• B. Testing for PKU is done immediately after birth.
• C. Treatment for PKU includes lifelong dietary management.
• D. PKU is transmitted by an autosomal recessive gene.

Correct answer: A

Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that, if left untreated with dietary management, can lead to severe mental retardation due to the accumulation of phenylalanine. It is crucial for parents to understand the potential consequences of untreated PKU to emphasize the importance of early and consistent treatment. Choice B is incorrect because testing for PKU is typically done through newborn screening shortly after birth, not immediately. Choice C is incorrect as treatment for PKU primarily involves strict dietary management that restricts phenylalanine intake, not lifelong medications. Choice D is incorrect as PKU is inherited in an autosomal recessive pattern, meaning that both parents must pass on a mutated gene for the disorder to manifest.

4. A child is diagnosed with atopic dermatitis. Which laboratory test would the nurse expect the child to undergo to provide additional evidence for this condition?

• A. Erythrocyte sedimentation rate
• B. Potassium hydroxide prep
• C. Wound culture
• D. Serum immunoglobulin E (IgE) level

Correct answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.

5. The healthcare professional is assessing a 4-year-old client. Which finding suggests to the healthcare professional this child may have a genetic disorder?

• A. Inquiry reveals the child had feeding problems.
• B. The child weighs 40 lb (18.2 kg) and is 40 in (101.6 cm) in height.
• C. The child has low-set ears with lobe creases.
• D. The child can hop on one foot but cannot skip.

Correct answer: C

Rationale: Low-set ears with lobe creases are often associated with genetic disorders and can indicate underlying chromosomal abnormalities. This physical characteristic is known to be a common sign in various syndromes like Down syndrome. Choices A, B, and D are not directly linked to genetic disorders. Feeding problems and specific weight/height measurements are more general indicators of growth and development, while the ability to hop on one foot but not skip is a developmental milestone assessment that does not specifically point towards a genetic disorder.
