A nurse is providing discharge teaching to a client who has a hearing impairment and a new hearing aid. Which of the following client statements indicates an understanding of the teaching?

A) Cimetidine: Cimetidine is an H2 receptor antagonist used to reduce stomach acid and treat conditions such as peptic ulcers and gastroesophageal reflux disease (GERD). It is not used to manage metabolic acidosis.

B) Calcitonin: Calcitonin is used to regulate calcium levels and treat conditions like osteoporosis or hypercalcemia. It does not address metabolic acidosis and is not appropriate for this condition.

C) Sodium bicarbonate: Sodium bicarbonate is commonly used to treat metabolic acidosis. It works by neutralizing excess acid in the blood, thereby increasing the blood's pH and helping to correct the acid-base imbalance associated with metabolic acidosis.

D) Sodium chloride: Sodium chloride is a salt that can be used to manage fluid and electrolyte imbalances but does not correct metabolic acidosis. It is not suitable for treating the acid-base imbalance seen in metabolic acidosis.

A) "You should remain on a clear liquid diet for 1 week after surgery.": After a laparoscopic cholecystectomy, clients do not need to remain on a clear liquid diet for a week. They can usually progress to a regular diet as tolerated, starting with light meals and avoiding fatty, greasy foods initially to prevent discomfort.

B) "Avoid showering for 1 week after surgery.": Clients are typically allowed to shower within a day or two after surgery, as long as they avoid soaking the incisions in water and follow the healthcare provider's instructions for incision care. Avoiding showering for a week is generally unnecessary and may hinder hygiene.

C) "Cleanse the incision sites with hydrogen peroxide.": Hydrogen peroxide can delay wound healing and is not recommended for routine incision care. The nurse should advise the client to cleanse the incision sites with mild soap and water and pat them dry.

D) "Apply heat to the right shoulder for pain.": Applying heat to the right shoulder can help relieve referred pain often experienced after a laparoscopic cholecystectomy due to residual gas used during the procedure. This is a common and effective method for managing postoperative discomfort.
