Correct Answer: D

Rationale: In this scenario, the 12-year-old male with a heart rate of 135 beats/minute, respirations of 20 breaths/minute, and blood pressure of 90/60 after falling during a skateboarding trick exhibits signs of shock. Weak and rapid peripheral pulses are concerning as they may indicate decreased cardiac output and tissue perfusion, which are signs of shock. This finding should be reported to the healthcare provider immediately for further evaluation and intervention to prevent potential complications. The other choices are less urgent. Complaints of back soreness (choice A) could be related to musculoskeletal injury. Capillary refill less than 2 seconds (choice B) is within the normal range, indicating adequate peripheral perfusion. A blood pressure of 94/68 (choice C) is slightly higher than the initial reading and may be compensatory in response to the fall and shock state.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to document the finding. The infant voiding a urinary stream from the ventral surface of the penis suggests hypospadias, a condition where the urethral opening is on the underside of the penis. This finding is crucial information that needs to be documented for further evaluation. Palpating the scrotum for testicular descent, assessing for bladder distension, and auscultating bowel sounds are not appropriate actions based on the presented scenario and do not address the specific concern of the urinary stream location.

Correct Answer: A

Rationale: The ability to laugh readily and turn from back to side indicates the effectiveness of thyroid therapy and normal development in a 5-month-old. These behaviors suggest improved muscle tone and motor skills, which are positive outcomes of thyroid hormone replacement therapy for hypothyroidism. Choices B, C, and D describe developmental milestones that are not specific indicators of the effectiveness of thyroid therapy in treating hypothyroidism in a 5-month-old.

Correct Answer: C

Rationale: Referring the child to the school counselor for educational testing is the most appropriate action in this scenario. This step can help identify the specific learning needs of the student and determine the appropriate interventions required to support his academic success. Option A is not the immediate action needed but may be considered in the future. Option B focuses on homework assistance, which may not address the underlying learning problems. Option D involves consulting the school principal, which is not the primary role in addressing the student's learning needs.

Correct Answer: C

Rationale: In a child with pneumonia who is breathing rapidly, the priority action for the nurse is to start the child on oxygen therapy. This intervention is essential to ensure adequate oxygenation, which is crucial in managing respiratory distress and preventing complications associated with hypoxia. Administering antipyretic medication (Choice A) may help reduce the fever but does not address the immediate need for oxygen therapy. Obtaining a chest X-ray (Choice B) is important for diagnosis but providing oxygen is more urgent. Notifying the healthcare provider (Choice D) can be done after initiating oxygen therapy to update on the patient's condition.
