A nurse is reinforcing discharge teaching with a client who has a prescription for antibiotictherapy. The client reports experiencing diarrhea when taking antibiotics. Which of the following foods should the nurse recommend to lessen the occurrence of diarrhea?

The correct answer is B. Placement of a central venous catheter.

Rationale: The nurse should identify that informed consent is required for the placement of a central venous catheter, as this is an invasive procedure that carries significant risks and benefits that need to be explained to the client before obtaining consent. Informed consent is not required for irrigation of a wound with antibiotic solution, as this is a routine nursing intervention that does not involve significant risks or benefits.

Informed consent is not required for the insertion of a nasogastric tube, as this is a common nursing procedure that does not involve significant risks or benefits. Informed consent is not required for the administration of an iron injection using the Z-track technique, as this is a standard medication administration technique that does not involve significant risks or benefits.

The correct answer is choice C. Clean the stoma using an inward to outward circular motion.

Choice A rationale:

Cleansing the inner cannula with isopropyl alcohol is not recommended because it can be irritating to the mucosa. Instead, the inner cannula should be cleaned with sterile saline or a prescribed solution.

Choice B rationale:

Preparing sterile supplies after removing the inner cannula is not the correct sequence. Sterile supplies should be prepared before starting the procedure to maintain sterility and efficiency.

Choice C rationale:

Cleaning the stoma using an inward to outward circular motion is correct because it helps to prevent the spread of microorganisms from the outer skin to the stoma site, reducing the risk of infection.

Choice D rationale:

Ensuring at least three finger widths of space under tracheostomy ties is incorrect. The correct practice is to ensure that only one to two finger widths can fit under the tracheostomy ties to ensure they are secure but not too tight.
