Options (a) Withhold the medication and (b) Administering a hypertonic solution may be appropriate interventions depending on the client's condition, but confirming the potassium level is the first step.

The nurse is responsible for maintaining an accurate count of all surgical items to prevent leaving any foreign objects inside the patient after the surgery. This is a crucial task to ensure patient safety and prevent any potential complications that may arise from such errors.

Option c. passing instruments to the surgeon and assistants, is a scrub nurse function that requires knowledge of the surgical procedure and a sterile technique.

Option d. preparing the instrument table and sterile equipment is also a scrub nurse function that requires expertise in sterile technique, knowledge of surgical procedures, and the ability to maintain a sterile environment.
