Pediatric HESI Practice Questions

Correct Answer: C

Rationale: The correct answer is Chickenpox (varicella). This viral disease typically starts with malaise and a highly pruritic rash that begins on the abdomen and then spreads to the face and proximal extremities. Chickenpox can result in serious complications such as pneumonia and encephalitis. Rubella (German measles) presents with a milder rash and is less pruritic than chickenpox. Rubeola (measles) is characterized by a rash that spreads from the head to the trunk. Scarlet fever is caused by group A Streptococcus bacteria and is not a viral illness.

Correct Answer: B

Rationale: Allowing the child to play with a favorite toy while taking the medication is the best approach to gain the child's cooperation. This strategy can help distract and calm the child, making the medication administration process smoother. Explaining the medication's importance (Choice A) may not be as effective in gaining immediate cooperation from a young child who may not fully understand. Offering a reward after the medication is taken (Choice C) may create a dependency on rewards for cooperation. Giving the medication mixed with food (Choice D) may not always be appropriate or recommended, especially if the child needs to take the medication on an empty stomach.

Correct Answer: C

Rationale: The most appropriate nursing diagnosis for a child with acute glomerulonephritis is 'Fluid volume excess related to decreased plasma filtration.' Acute glomerulonephritis is characterized by inflammation in the glomeruli, leading to decreased plasma filtration and retention of fluid. This results in fluid volume excess rather than deficit, making choice C the correct answer. Choice A is incorrect because acute glomerulonephritis is not primarily associated with a malignant process. Choice B is incorrect as the condition typically presents with fluid volume excess rather than deficit. Choice D is also incorrect as fluid accumulation in tissues and third spaces is not a typical manifestation of acute glomerulonephritis.

Correct Answer: D

Rationale: The correct answer is 'Low-grade fever.' A low-grade fever is a typical, mild side effect that can occur after the Hib vaccine is administered. It is a sign that the body's immune system is responding to the vaccine and is generally not a cause for concern. Lethargy, urticaria, and generalized rash are not commonly associated side effects of the Hib vaccine. Lethargy may be a sign of other issues, while urticaria and generalized rash are more indicative of allergic reactions rather than typical responses to the Hib vaccine.

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.
