A nurse is teaching about safe handling of formula to a client who is postpartum and chooses to bottle feed her newborn.
Which of the following statements by the client indicates an understanding of the teaching?

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.

Choice A rationale:

Wire cutters are not necessary equipment for postoperative care after a thoracotomy with chest tube placement. Wire cutters are used for cutting wires and may be found in orthopedic or surgical trays, but they are not specifically required for thoracotomy care.

Choice B rationale:

A tracheostomy tray is not necessary for postoperative care following a thoracotomy with chest tube placement. Tracheostomy trays contain supplies for managing a tracheostomy, which is a procedure involving the creation of an opening in the neck to help with breathing. This procedure is not related to thoracotomy care.

Choice C rationale:

Montgomery straps are not necessary equipment for postoperative care after a thoracotomy with chest tube placement. Montgomery straps are used to secure dressings or bandages without adhesive tape. They are not typically used in thoracotomy care.

Choice D rationale:

A padded clamp is essential equipment for postoperative care after a thoracotomy with chest tube placement. The clamp is used to temporarily close or occlude the chest tube during transportation or when changing the drainage system. This prevents air from entering the pleural space, maintaining proper suction and preventing complications such as pneumothorax.
