HESI Pediatrics Quizlet

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: C

Rationale: Moving a child to a regular bed by the appropriate age is not recommended as it can increase the risk of falls. Toddlers should transition to a regular bed only when developmentally ready to prevent accidents. Keeping medications in a medicine cabinet (Choice A) promotes safety by preventing accidental ingestion. Securing gates at entrances to staircases (Choice B) helps prevent falls down stairs. Buying shoes that close with Velcro rather than laces (Choice D) is a good practice to prevent tripping and falling.

Correct Answer: D

Rationale: Negativism in toddlers is a common behavior at this age as they begin to assert their independence and show a desire to control their environment. Choice A, 'Trust,' does not align with the behavior of negativism, as it is more about the child's growing autonomy. Choice B, 'Attention,' while important for child development, is not the primary need being met by negativism in this context. Choice C, 'Discipline,' though important in guiding behavior, is not the underlying need being expressed through negativism. Therefore, the correct answer is D, 'Independence,' as toddlers exhibit negativism as a way to assert their independence and autonomy.

Correct Answer: B

Rationale: The correct answer is B: Diphtheria, pertussis, tetanus, and polio. By 11 months of age, infants should have received doses of these vaccines as part of the immunization schedule. Choice A is incorrect because measles is usually given later in the schedule. Choice C is incorrect as rubella is usually given as part of the MMR vaccine, not individually, and tuberculosis is not routinely given as a vaccine in early infancy. Choice D is incorrect because mumps is not part of the recommended vaccines at 11 months of age.

Correct Answer: C

Rationale: The correct answer is to record the best of three attempts when using a peak flow meter. This method provides a more accurate measure of peak expiratory flow. Choice A is incorrect because using the device before taking medication may not reflect the actual peak flow, as medication can affect lung function. Choice B is incorrect as using the device during asthma attacks may not be feasible or safe, as the focus during an attack should be on managing symptoms rather than measuring peak flow. Choice D is incorrect because using the device after eating may not provide an accurate measurement of peak flow, as digestion can affect lung function temporarily.
