Correct Answer: A

Rationale: In the DSM V, one of the key diagnostic criteria for Autism Spectrum Disorder (ASD) is unusual responses to sensory input. These atypical responses can include hypersensitivity or hyposensitivity to sensory stimuli, such as sound, touch, taste, or smell. These sensory processing differences are important in the diagnosis of ASD because they can significantly impact an individual's daily functioning and behavior.

Correct Answer: A

Rationale: Applying an anesthetic cream to the insertion site 1 hr before the procedure is crucial when inserting an intravenous catheter in a child to minimize pain and discomfort during the procedure. This practice is especially important in pediatric patients to ensure a more comfortable experience and improve cooperation during the insertion process.

Correct Answer: C

Rationale: Preschool-age children with a urinary tract infection commonly present with urgency (feeling the need to urinate urgently), dysuria (painful urination), and fever. These symptoms are indicative of a UTI in this age group and should prompt further assessment and intervention by the nurse.

Correct Answer: D

Rationale: The correct answer is D: BP of 70/50. When sildenafil (Viagra) is taken with nitroglycerin, it can cause severe hypotension that is unresponsive to treatment. The combination of these medications can lead to a dangerous drop in blood pressure. It is crucial to immediately report hypotension in this scenario. It is recommended to allow at least 24 hours to elapse between the last dose of sildenafil and nitroglycerin to prevent such adverse effects. The other vital signs and lab values may be abnormal but do not have the immediate life-threatening implications that severe hypotension does in this context.

Correct Answer: C

Rationale: In nephrotic syndrome, monitoring urine for protein is essential as it helps track the child's condition. Checking urine for protein should be done as part of the discharge teaching to keep a record of the child's urinary proteins and to monitor the effectiveness of the treatment plan. It is crucial for parents to understand this aspect of care to ensure proper management of the child's condition.
