A nurse is preparing to witness a client's signature on a consent form for a colon resection. The nurse should recognize that which of the follow information should be provided to the client by the provider before signing the form? (Select all that apply.)

Rationale:

A. How to change the tracheostomy dressing using clean technique: Tracheostomy dressings should be changed using sterile technique, not clean technique, to prevent infection and protect the airway. Teaching clean technique would be inappropriate.

B. How to operate the portable suction machine: Suctioning is a critical skill for maintaining airway patency and preventing respiratory complications. Teaching the partner how to operate the suction machine ensures they can assist safely at home if needed.

C. How to change the nondisposable tracheostomy tube daily: Nondisposable tracheostomy tubes are not typically changed daily; frequent changes can damage the stoma or airway. Tube changes are usually performed by trained healthcare personnel.

D. How to secure the tracheostomy tube with ties at the back of the neck: Ties should be secured in a way that avoids pressure or friction on the back of the neck, typically fastening at the sides. Focusing on back-of-neck placement could lead to skin breakdown or discomfort.

Rationale:

A. Serum potassium: Spironolactone is a potassium-sparing diuretic that can cause hyperkalemia. Monitoring serum potassium is essential to detect elevated levels early and prevent cardiac complications.

B. Platelet count: Spironolactone does not significantly affect platelet production or function, so routine monitoring of platelets is not indicated for this medication.

C. Urine ketones: Ketone monitoring is relevant for clients with uncontrolled diabetes or ketosis, but it is not related to spironolactone therapy.

D. Total bilirubin: Bilirubin levels are used to assess liver function, which is not directly affected by spironolactone in most clients, so routine monitoring is not necessary unless the client has underlying hepatic disease.
