A. Auscultation. Auscultation involves listening to internal body sounds, usually with a stethoscope, such as heart, lung, or bowel sounds. It is not used for assessing the radial pulse.
B. Percussion. Percussion is the technique of tapping on body surfaces to assess underlying structures, such as detecting fluid in the lungs or assessing organ size. It is not used to assess pulses.
C. Palpation. Palpation involves using the fingers to feel for the radial pulse by applying gentle pressure over the radial artery at the wrist. This is the correct method for assessing a patient's radial pulse.
D. Inspection. Inspection involves visually examining the patient for abnormalities such as skin color, swelling, or deformities. It does not provide information about pulse rate or rhythm.

A. Hyperventilation. Opioid overdose depresses the central nervous system, leading to slow and shallow breathing, not increased respiratory rate (hyperventilation).
B. Eupnea. Eupnea refers to normal breathing, which is unlikely in opioid overdose because opioids suppress respiratory drive.
C. Bradypnea. Opioids act on the brainstem's respiratory centers, leading to respiratory depression, characterized by slow breathing (bradypnea) and, in severe cases, respiratory arrest. This is the most life-threatening effect requiring immediate intervention.
D. Hyperpnea. Hyperpnea refers to deep breathing, which is not a typical response to opioid overdose. Instead, breathing becomes slow and shallow, increasing the risk of hypoxia.
