Pediatric Practice Exam HESI

Correct Answer: D

Rationale: Hypospadias is a congenital condition where the urethral opening is located along the ventral surface of the penis, not the dorsal surface (Choice C) or absent (Choice A). This leads to the characteristic appearance of a ventrally displaced urethral meatus. The penis may appear normal in size but with the urethral opening positioned abnormally (Choice D), rather than being shorter than usual (Choice B). Therefore, the correct expectation for a newborn with hypospadias is that the urethral opening is along the ventral surface of the penis, making Choice D the correct answer.

Correct Answer: B

Rationale: The correct answer is B: 'Warmth at skin disruption site.' Cellulitis is characterized by localized warmth at the site of skin disruption, which indicates an infection. Choice A, 'Red, raised hair follicles,' is more typical of folliculitis. Choice C, 'Papules progressing to vesicles,' is suggestive of conditions like herpes simplex virus infections. Choice D, 'Honey-colored exudate,' is associated with impetigo, not cellulitis. When assessing cellulitis, nurses should primarily look for warmth, erythema, edema, and tenderness at the affected site.

Correct Answer: C

Rationale: Keeping the newborn warm is crucial as newborns are at high risk of hypothermia due to their large body surface area and limited subcutaneous fat. Hypothermia can lead to complications such as respiratory distress, hypoglycemia, and metabolic acidosis. Providing warmth helps maintain the newborn's body temperature and supports physiological processes, promoting overall well-being. Applying free-flow oxygen is not necessary if the newborn is not in distress. Clamping and cutting the cord can be done after addressing the immediate need for warmth. Obtaining an APGAR score is important for assessing the newborn's overall condition but ensuring warmth takes precedence to prevent complications related to hypothermia.

Correct Answer: A

Rationale: The correct answer is A: 'High fever and Koplik spots.' Rubeola (measles) is characterized by a high fever and the presence of Koplik spots, which are not seen in rubella (German measles). Choice B, rash on the trunk with pruritus, is more indicative of rubella. Choice C, nausea, vomiting, and abdominal cramps, are not specific to either rubeola or rubella. Choice D, characteristics of a cold followed by a rash, is not a typical presentation of rubeola or rubella.

Correct Answer: B

Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas do not directly lead to loss of necessary nutrients. Choice C is incorrect as it focuses on emotional impact rather than physiological risks. Choice D is incorrect as shock from a sudden drop in temperature is not a common consequence of a tap water enema in this scenario.
