Pediatric Practice Exam HESI

Correct Answer: D

Rationale: Testing the temperature of water before bathing is crucial to prevent burns, which is a significant risk for infants due to their sensitive skin. Infants have delicate skin that can easily be burned by water that is too hot. Testing the water temperature before bathing ensures that the water is at a safe and comfortable level for the infant. While choices A, B, and C are also important in accident prevention, such as reducing choking hazards, preventing electric shocks, and avoiding poisoning, testing the water temperature before bathing is the most immediate and direct action to prevent harm to the infant during bathing.

Correct Answer: A

Rationale: When a child with diabetes insipidus is treated with vasopressin, the nurse should closely monitor for signs and symptoms of Syndrome of Inappropriate Antidiuretic Hormone (SIADH). Vasopressin, also known as antidiuretic hormone, helps retain water in the body. Excessive vasopressin administration can lead to water retention, dilutional hyponatremia, and potentially result in SIADH. Choices B, C, and D are incorrect because they are not directly associated with the use of vasopressin in treating diabetes insipidus.

Correct Answer: D

Rationale: Withholding extraordinary care in cases of severe abnormalities is a legal and ethical decision. It allows the newborn to die naturally without aggressive interventions. Choice A is incorrect because all individuals, including newborns, have rights. Choice B is incorrect because withholding extraordinary care is not equivalent to euthanasia, which involves actively ending a life. Choice C is incorrect because such decisions are legally and ethically permissible when made in consideration of the best interests of the newborn.

Correct Answer: B

Rationale: Using a doll to demonstrate the procedure is the most appropriate preoperative teaching method for a 2-year-old child. It helps them understand what to expect in a non-threatening way by providing a visual representation of the upcoming surgery. Explaining the procedure in simple terms may be too abstract for a child of this age, as they may not fully comprehend verbal explanations. Showing pictures of the hospital environment may not be as effective as using a doll, as it may not provide a concrete understanding of the actual procedure. Allowing the child to play with medical equipment is unsafe and does not adequately prepare them for the surgery, as it may lead to misunderstandings or fear regarding the equipment's actual use during the surgery.

Correct Answer: A

Rationale: The priority nursing intervention for a child with leukemia receiving chemotherapy is monitoring for signs of infection. Chemotherapy can suppress the immune system, putting the child at a higher risk of developing infections. Early detection of signs of infection is crucial to prevent serious complications and initiate timely treatment. Providing nutritional support is important for overall health but is not the priority when the child is at risk of infection. Monitoring for signs of bleeding is essential, but infection surveillance takes precedence due to the immediate threat it poses to the child's health. Monitoring for signs of pain is important for comfort but is not the priority over infection prevention and management.
