HESI Pediatrics Quizlet

Correct Answer: C

Rationale: The correct answer is C. Infants may have difficulty regulating glucose and electrolytes due to their immature endocrine systems. This can lead to issues such as hypoglycemia and electrolyte imbalances. Choice A is incorrect because endocrine glands actually begin developing early in gestation, not just in the third trimester. Choice B is incorrect as endocrine glands are not fully functional at birth; they continue to mature and develop after birth. Choice D is incorrect as a child's endocrine system has a significant impact on growth and development through the secretion of hormones that regulate various processes in the body, but it does not specifically address the difficulty in regulating glucose and electrolytes seen in infants.

Correct Answer: A

Rationale: The correct answer is A: Varicella (Chickenpox). Varicella can lead to the complication of encephalitis, characterized by brain inflammation. Encephalitis is a known complication of chickenpox in rare cases. Scarlet fever (choice B) is caused by Streptococcus bacteria and does not typically result in encephalitis. Poliomyelitis (choice C) primarily affects the spinal cord and does not lead to encephalitis. Whooping cough (choice D) can cause severe coughing spells but does not directly result in encephalitis.

Correct Answer: B

Rationale: Monitoring the intravenous drop rate is the most crucial intervention when administering IV fluids to a dehydrated infant. This ensures that the correct amount of fluids is being delivered to the infant at the appropriate rate. While continuing the prescribed flow rate (Choice A) may be important, it does not allow for real-time adjustments that may be necessary during the infusion. Calculating the total necessary intake (Choice C) should have been determined before initiating IV therapy. Maintaining the fluid at body temperature (Choice D) is important for patient comfort but is not as critical as ensuring the proper administration of fluids.

Correct Answer: C

Rationale: The correct answer is to 'Record the best of three attempts.' This method provides an accurate measure of peak expiratory flow using a peak flow meter. By taking the best of three attempts, the child and parents can obtain a more reliable assessment of the child's lung function. Choices A, B, and D are incorrect because using the device before taking medication, during asthma attacks, or after eating does not ensure an accurate measurement of peak flow, which is essential for managing asthma effectively. Monitoring peak flow regularly and accurately can help in adjusting asthma treatment plans and assessing response to medications.

Correct Answer: B

Rationale: When a limb is protruding from the vagina during active labor, the appropriate management includes positioning the mother in a head-down position with her hips elevated. This position helps relieve pressure on the umbilical cord, reducing the risk of compromising fetal blood flow and oxygenation. Administering oxygen is essential to maintain oxygenation levels for both the mother and the fetus. Providing transport to a healthcare facility equipped to manage this obstetric emergency is crucial for ensuring a safe delivery. Choice A is incorrect because a semi-Fowler's position does not effectively relieve pressure on the umbilical cord. Choice C is incorrect as applying traction to the protruding limb can lead to injury or complications for both the mother and the fetus. Choice D is incorrect because attempting to manipulate the limb without proper positioning and preparation can worsen the situation and increase risks during delivery.
