HESI Pediatrics Quizlet

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.

Correct Answer: A

Rationale: Preventing shivering is crucial in this scenario as it can increase body temperature and counteract the effects of antipyretic measures aimed at reducing the fever. Shivering generates heat through muscle activity, which can elevate the body temperature. Restricting oral fluids (choice B) is inappropriate as maintaining hydration is vital, especially in cases of fever and vomiting. Measuring output hourly (choice C) and taking vital signs hourly (choice D) are important nursing actions but not the most critical in this case where preventing shivering takes precedence.

Correct Answer: B

Rationale: Clubbing of fingers is a common manifestation in children with tetralogy of Fallot due to chronic hypoxia. Clubbing occurs as a result of long-standing decreased oxygen levels in the blood, leading to changes in the fingertips. Slow respirations (Choice A) are not typically a direct clinical manifestation of tetralogy of Fallot. While decreased RBC counts (Choice C) may occur due to chronic hypoxia, they are not a primary manifestation specific to tetralogy of Fallot. Subcutaneous hemorrhages (Choice D) are not a common clinical manifestation associated with tetralogy of Fallot.

Correct Answer: D

Rationale: Asking the parents if they smoke in the home is the most relevant question as exposure to secondhand smoke can exacerbate respiratory symptoms like wheezing and difficulty breathing in children. This information is crucial for identifying potential triggers for the child's symptoms. Inquiring about child safety in the home, asking about the child's temperament, and inquiring about the child's diet, while important aspects of care, may not directly address the respiratory symptoms the child is experiencing.

Correct Answer: D

Rationale: Performing a comprehensive health assessment is crucial for a child living with a foster family as they may have moved between different homes, leading to incomplete medical records. This assessment helps identify any existing health issues, ensure appropriate care, and address any unmet health needs. While addressing issues like bullying or parental expectations is important, the immediate priority should be ensuring the child's overall health and well-being. Establishing the actual caretaker is also important but may not be as urgent as addressing potential health concerns.
