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?

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 a nonspecific test for inflammation and not specific to atopic dermatitis. Choice B, potassium hydroxide prep, is used to diagnose fungal infections like tinea versicolor, not atopic dermatitis. Choice C, wound culture, is not typically indicated for the diagnosis of atopic dermatitis as it is a chronic inflammatory skin condition rather than an infectious process.

Correct Answer: B

Rationale: Establishing a bedtime routine is the most appropriate suggestion for a child experiencing night terrors. Consistent bedtime routines help create a sense of security and predictability, reducing the likelihood of night terrors. Encouraging the child to talk about the dream (Choice A) may not be effective as night terrors occur during non-REM sleep, and the child may not remember the dreams. Allowing the child to sleep with the parents (Choice C) can reinforce dependency and may not address the underlying causes of night terrors. Waking the child during the night (Choice D) can disrupt their sleep cycle and worsen the occurrence of night terrors.

Correct Answer: C

Rationale: In a congenital cardiac malformation causing right-to-left shunting, the nurse should expect an elevated hematocrit. This occurs because the body compensates for decreased oxygenation by producing more red blood cells. Proteinuria (Choice A) is not typically associated with congenital cardiac malformations causing right-to-left shunting. Peripheral edema (Choice B) is more commonly seen in conditions causing left-sided heart failure. Absence of pedal pulses (Choice D) is not a typical finding in congenital cardiac malformations causing right-to-left shunting.

Correct Answer: D

Rationale: The correct answer is D: "This is a lifelong problem, and it is recommended that dietary restrictions must be continued." PKU requires a lifelong adherence to a specific diet low in phenylalanine to prevent cognitive and developmental issues. Phenylalanine buildup can lead to irreversible damage, making it crucial for individuals with PKU to maintain dietary restrictions throughout their lives. Choices A, B, and C are incorrect because they do not address the lifelong nature of dietary restrictions necessary for PKU management.

Correct Answer: A

Rationale: Monitoring fluid status is crucial for a child with congenital heart disease because these children are at risk of fluid overload which can worsen their condition. Monitoring fluid intake and output helps prevent complications like congestive heart failure. Encouraging activity (Choice B) should be individualized based on the child's condition and tolerance, as excessive activity can strain the heart. Promoting a high-calorie diet (Choice C) is not typically recommended for children with congenital heart disease unless specifically indicated, as excessive weight gain can worsen their cardiac function. Maintaining oxygen therapy (Choice D) may be necessary in some cases, but monitoring fluid status is a more fundamental aspect of care for children with congenital heart disease.

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.

Correct Answer: C

Rationale: A moist sterile dressing should be used to protect the exposed bladder tissue from infection and injury. Exstrophy of the bladder requires careful management to prevent complications such as infection. A loose diaper (Choice A) may not provide adequate protection or prevent infection. Dry gauze dressing (Choice B) may not be ideal as it could adhere to the exposed area and cause trauma upon removal. Petroleum jelly gauze pad (Choice D) may not be suitable as it can trap moisture and increase the risk of infection.

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.

Correct Answer: A

Rationale: Monitoring fluid status is crucial for a child with congenital heart disease because these children are at risk of fluid overload, which can exacerbate their condition. Monitoring fluid intake and output helps prevent complications such as heart failure. Encouraging activity may be important, but it should be done cautiously and within limits due to the child's cardiac condition. Promoting a high-calorie diet is not typically a priority in congenital heart disease care unless there are specific indications. Maintaining oxygen therapy may be necessary in some cases but is not the primary intervention for managing congenital heart disease.
