HESI Pediatrics Quizlet

Correct Answer: B

Rationale: The correct answer is B: systolic blood pressure. In young children, systolic blood pressure is the least reliable parameter for assessing perfusion status. Factors such as anxiety, crying, and fear can significantly affect blood pressure measurements, leading to inaccuracies. Distal capillary refill, skin color and temperature, and presence of peripheral pulses are more reliable indicators of perfusion status in pediatric patients. Distal capillary refill assesses peripheral perfusion, skin color, and temperature reflect tissue perfusion, and the presence of peripheral pulses indicates blood flow to the extremities. Therefore, when evaluating a 2-year-old child with possible shock, focusing on parameters other than systolic blood pressure is crucial for an accurate assessment of perfusion status.

Correct Answer: D

Rationale: When counseling a couple about the possibility of having a child with a genetic abnormality, it is vital for the nurse to present information in a nondirective manner. This approach empowers the couple to make decisions based on their values and preferences, respecting their autonomy. Gathering information from three generations (Choice A) may not be necessary and might overwhelm the couple with unnecessary data. Informing the family about the need for a wide range of information (Choice B) is not as critical as supporting their decision-making process through a nondirective approach. While maintaining confidentiality (Choice C) is crucial, it is not the most important aspect compared to ensuring the couple can make informed choices that align with their beliefs and wishes.

Correct Answer: A

Rationale: The correct answer is A. Applying ice in intervals helps to reduce swelling and pain in the first 24 hours after a sprain. This intervention is crucial in the initial management of a sprain to decrease inflammation and provide pain relief. Bed rest with the leg elevated for 36 hours (Choice B) is not recommended as prolonged immobilization can lead to stiffness and decreased range of motion. Allowing the child to take an NSAID for pain as prescribed (Choice C) is a supportive measure but not as essential as ice application in the acute phase. Using a compression dressing for 72 hours (Choice D) may assist in reducing swelling, but it is not as critical as the immediate application of ice to manage pain and inflammation effectively.

Correct Answer: A

Rationale: Infection is the most common cause of shock in infants and children due to their increased susceptibility to sepsis. Infants and children have underdeveloped immune systems, making them more prone to infections that can lead to septic shock. While cardiac failure is a serious condition, it is not the most common cause of shock in this population. Accidental poisoning, though dangerous, is less common than infection in causing shock in infants and children. Severe allergic reactions can lead to anaphylactic shock, but they are not as prevalent as infections in causing shock in this age group.

Correct Answer: B

Rationale: Encouraging deep breathing exercises is crucial preoperative teaching for a child scheduled for a tonsillectomy as it helps improve lung function and can prevent postoperative complications like pneumonia. Explaining the procedure in detail may heighten the child's anxiety, making it less ideal. While discussing hydration is important, it may not be the top priority for preoperative teaching for this specific procedure. Play therapy can reduce fear and anxiety, but encouraging deep breathing exercises directly contributes to better postoperative outcomes by enhancing respiratory function.
