Pediatric HESI Practice Questions

Correct Answer: A

Rationale: Incisors are the teeth that typically erupt first in infants, usually around 6 months of age. These teeth play a crucial role in biting and cutting food. Canines, upper molars, and lower molars are not the primary teeth to erupt in infants. Canines usually erupt after incisors, while molars, whether upper or lower, come in later during the teething process.

Correct Answer: C

Rationale: In a child with a congenital cardiac malformation causing right-to-left shunting of blood, the nurse should expect an elevated hematocrit. This occurs because the body compensates for decreased oxygenation by producing more red blood cells. Proteinuria (Choice A) is not a typical clinical finding related to right-to-left shunting. Peripheral edema (Choice B) is more commonly associated with conditions causing volume overload, such as left-sided heart failure. Absence of pedal pulses (Choice D) is not directly related to right-to-left shunting but may be seen in conditions affecting peripheral circulation.

Correct Answer: C

Rationale: The correct answer is C: A ready source of glucose should be available. When managing type 1 diabetes, it is crucial to have a quick source of glucose readily available in case of hypoglycemia. This ensures that the adolescent can quickly raise their blood sugar levels to prevent complications. Choices A, B, and D are incorrect as they do not address the immediate need for glucose in managing hypoglycemia. While it is important for meals to be consumed regularly and in a controlled manner, specifying that they should be eaten at home or foods weighed using a gram scale is not as critical as ensuring a quick source of glucose in emergency situations.

Correct Answer: C

Rationale: Infants receive passive immunity through antibodies from the mother during pregnancy and breastfeeding, which protect them initially.

Correct Answer: B

Rationale: The primary function of the endocrine system is hormonal secretion. This system is responsible for producing and releasing hormones that regulate various bodily functions such as growth, metabolism, and mood. Choice A, regulation of water balance, is more related to the functions of the renal system rather than the endocrine system. Choice C, cellular metabolism, is a general cellular process that involves various systems, not specific to the endocrine system. Choice D, growth stimulation, though hormones can influence growth, it is not the primary function of the endocrine system. Therefore, the correct answer is B.
