Pediatric HESI Test Bank

Correct Answer: A

Rationale: Explaining the procedure in simple terms is essential preoperative teaching for a 4-year-old child scheduled for a myringotomy. This approach helps the child understand what will happen during the procedure, reducing anxiety and fear. Encouraging fluid intake is a good general health practice but not directly related to preoperative teaching for this procedure. Allowing the child to play with medical equipment may not be safe or appropriate as it can lead to misunderstanding or fear. Using play therapy can be beneficial but explaining the procedure in simple terms is more direct and effective for preoperative teaching in this case.

Correct Answer: C

Rationale: Administering antibiotics is a crucial nursing intervention after a tonsillectomy because it helps prevent infections, which are a common postoperative complication. Encouraging deep breathing exercises (Choice A) is also important for promoting lung expansion and preventing respiratory complications. Encouraging the child to eat (Choice B) may not be appropriate immediately after a tonsillectomy due to the risk of throat irritation and discomfort. Applying ice to the throat (Choice D) is generally not recommended post-tonsillectomy as it may cause vasoconstriction and hinder the healing process.

Correct Answer: C

Rationale: The correct answer is C: 37% to 47%. The normal hematocrit range for a 12-month-old infant is between 37% to 47%, which reflects the expected blood volume and red blood cell levels for this age. Choice A (19% to 32%) and Choice B (29% to 41%) are too low and do not encompass the typical hematocrit range for a healthy 1-year-old. Choice D (42% to 69%) is too high and falls outside the usual hematocrit values for this age group.

Correct Answer: B

Rationale: The correct initial action during a tonic-clonic seizure is to place the child on the floor to prevent injury. This action helps protect the child from falling off the chair and provides a safer environment for the seizure to occur. Attempting to open the jaw can cause harm or injury. Calling out for assistance is important but should follow the immediate action of moving the child to the floor. Placing a pillow under the child's head is not recommended as it may lead to airway obstruction or further injury during the seizure.

Correct Answer: C

Rationale: Phenylketonuria (PKU) is suggested by a mousy or musty odor of the urine, caused by the inability to metabolize phenylalanine. Maple syrup urine disease (Choice A) is characterized by a sweet-smelling urine. Tyrosinemia (Choice B) presents with cabbage-like odor in the urine. Trimethylaminuria (Choice D) results in a fishy odor in the urine, breath, and sweat.
