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 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.

Correct Answer: B

Rationale: The nurse's best response is to allow the tantrum to continue until it ends without giving in to the child's demands. By not rewarding the child with the desired item during a tantrum, the child learns that this behavior is not effective in getting what they want. Offering a toy to distract the child (Choice A) may reinforce the idea that tantrums lead to rewards. Leaving the child with a babysitter (Choice C) does not address the issue at hand, which is teaching the child appropriate behavior in public places. Giving the child the item temporarily (Choice D) may encourage the child to have tantrums in the future to obtain desired items.

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: A respiratory rate of 50 breaths per minute in a 5-month-old infant is considered high and may indicate respiratory distress. Infants normally have a higher respiratory rate than older children and adults, but a rate of 50 breaths per minute is above the expected range. This finding warrants immediate attention as it may be indicative of an underlying respiratory issue or distress. Choice A (Temperature of 99.5�F) is within the normal range for body temperature and does not necessarily indicate a critical issue. Choice B (Blood pressure of 75/48 mm Hg) is not typically assessed in isolation for a 5-month-old infant during a routine examination, and the values provided are not indicative of a critical condition. Choice C (Heart rate of 100 beats per minute) is within the normal range for heart rate in infants and may not be a cause for immediate concern during a routine examination.

Correct Answer: D

Rationale: When a family decides to withhold 'extraordinary care' for a newborn with severe abnormalities, it means that aggressive interventions will not be pursued, allowing the newborn to die naturally. This decision is legal and ethical, respecting the principle of non-maleficence by avoiding unnecessary suffering. Choice A is incorrect because all individuals, including newborns, have rights, but the decision to withhold extraordinary care is based on ethical considerations. Choice B is incorrect as withholding care is not the same as euthanasia, which involves actively ending life. Choice C is incorrect as long as the decision is made within legal and ethical boundaries, it is not considered illegal professional practice.
