Rationale: Asking about developmental milestones such as the age at which a child started walking without assistance is considered an important part of the child's past medical history. This information helps the nurse assess if the child is meeting typical developmental milestones for their age. It also provides valuable insight into the child's growth and development, aiding in early identification of any potential developmental delays or concerns. Therefore, in the context of interviewing the mother of a 3-year-old child, inquiring about such developmental milestones is relevant and important for the child's past history.

Correct Answer: D

Rationale: In this scenario, the nurse's first action should be to obtain a Doppler ultrasound device to assess the pedal pulses. If the nurse was unable to palpate the pedal pulses initially, the use of a Doppler can help in accurately identifying the pulses. It is essential to confirm the absence or presence of peripheral pulses before taking any further actions. This will provide crucial information for the physician to determine the appropriate course of treatment. Conducting a Doppler assessment will assist in evaluating the severity of the situation and guide the next steps in the patient's care plan.

Correct Answer: B

Rationale: For effective defibrillation, the paddles should be placed at the apex and right infraclavicular area, ensuring optimal current flow through the heart to terminate life-threatening arrhythmias.

Correct Answer: A

Rationale: The patient shows severe signs of an eating disorder with critical physical parameters, necessitating immediate hospital admission.
