Pediatric Practice Exam HESI

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 are unlikely to lead to loss of necessary nutrients. Choice C is incorrect as it does not directly relate to the physiological risk of tap water enemas. Choice D is incorrect as shock from a sudden drop in temperature is not a common concern with tap water enemas.

Correct Answer: C

Rationale: The priority nursing intervention for a 4-year-old child admitted to the hospital with epiglottitis is to keep the child NPO (nothing by mouth). Epiglottitis is a serious condition that can lead to airway obstruction. Keeping the child NPO helps prevent further compromise of the airway and reduces the risk of aspiration. Administering antibiotics may be necessary but ensuring the airway is not compromised takes precedence. Providing humidified oxygen is important for respiratory support, but not the priority over maintaining a patent airway. Positioning the child upright can help with breathing and comfort, but it does not directly address the immediate risk of airway compromise associated with epiglottitis.

Correct Answer: B

Rationale: A cross-cut nipple is the most appropriate method to feed an infant born with a unilateral cleft lip and palate. Using a cross-cut nipple allows for easier feeding by modifying the flow of milk, which helps in reducing the risk of aspiration in infants with this condition. Plastic spoon, parenteral infusion, and rubber-tipped syringe are not suitable for feeding infants with cleft lip and palate. Feeding an infant with a cleft lip and palate requires special considerations to ensure safe and effective nutrition delivery.

Correct Answer: D

Rationale: Full-thickness burns, also known as third-degree burns, are characterized by a leathery, dry appearance with numbness due to nerve damage. This type of burn extends through all layers of the skin, affecting nerve endings. Choice A describes characteristics of superficial partial-thickness burns, which involve the epidermis and part of the dermis. Choice B describes characteristics of superficial burns, or first-degree burns, which only affect the epidermis. Choice C describes characteristics of superficial to mid-dermal burns, also known as second-degree burns, which involve the epidermis and part of the dermis but do not extend through all skin layers. Therefore, the correct answer is D.

Correct Answer: B

Rationale: Breastfeeding is recommended to help prevent constipation in infants due to the easily digestible nature of breast milk, which often leads to softer stools. Breastfeeding is preferred over formula feeding as it provides optimal nutrition for the infant's digestive system. Choice A, using a soy formula if necessary, may be considered only if there are specific dietary concerns or allergies; however, breast milk is still the preferred option. Choice C, avoiding administering a suppository nightly, is correct as it is not a routine method for preventing constipation in infants and may not be appropriate without medical advice. Choice D, not offering glucose water between feedings, is recommended as it may not address the root cause of constipation and may introduce unnecessary sugar to the infant's diet.
