A nurse is providing discharge teaching to a client who is 1 day postoperative following a right modified radical mastectomy.
Which of the following instructions should the nurse include in the teaching?

- A is incorrect because massaging bony prominences on the client's left side can increase the risk of skin breakdown and pressure ulcers. The nurse should avoid applying pressure to areas with impaired circulation or sensation.

- B is correct because supporting the client's left arm on a pillow while sitting can prevent edema, contractures, and nerve damage. The nurse should also encourage the client to perform active and passive range of motion exercises on their left arm.

- C is incorrect because positioning the bedside table on the client's left side can discourage the client from using their right side, which can lead to neglect and learned nonuse. The nurse should position the bedside table on the client's right side and encourage them to reach for items with their right hand.

- D is incorrect because placing the client's cane on their left side while ambulating can cause instability and falls. The nurse should place the cane on the client's right side and instruct them to move their left leg and cane together, followed by their right leg.

Choice A rationale:

The statement, "I will take the medication in the morning," indicates lack of understanding. Metformin is usually taken with large meals, and taking it in the morning is not the best timing.

Choice B rationale:

The statement, "I will expect to gain weight," is incorrect. Weight gain is not an expected side effect of metformin. In fact, metformin is often associated with weight loss or weight maintenance, especially in individuals with diabetes, as it helps improve insulin sensitivity and glucose metabolism.

Choice C rationale:

The statement, "I will take the medication on an empty stomach," is incorrect for extended-release metformin tablets. Unlike immediate-release metformin, extended-release tablets should be taken with meals to reduce the risk of gastrointestinal side effects.

Choice D rationale:

The statement, "I will avoid crushing this medication," is correct. Metformin extended-release tablets should never be crushed or broken, as it can affect the way the medication is released into the body. Crushing or breaking the tablet can lead to a sudden release of a large amount of metformin, potentially causing an overdose.
