A nurse is teaching the guardian of an infant who has developmental dysplasia of the hip about a Pavlik harness. Which of the following Instructions should the nurse include?

A. While it's important for the client to empty their bladder before surgery to reduce the risk of complications, administering a preoperative injection typically requires monitoring the client closely for any adverse reactions rather than immediately taking them to the bathroom.

B. Asking the client to verify the surgical site helps prevent wrong-site surgery and ensures proper patient safety protocols are followed.

C. Reviewing deep breathing and coughing exercises is an important preoperative teaching, but it's not typically done immediately after administering a preoperative injection.

D. Raising the side rails on the bed is a safety measure to prevent falls, but it's not directly related to administering a preoperative injection.

A. Arterial blood gases - Arterial blood gases are not typically assessed before initiating lithium carbonate therapy.

B. Total cholesterol - Total cholesterol levels are not specifically relevant to monitoring lithium therapy.

C. Thyroid hormones - Thyroid function should be assessed before initiating lithium therapy because lithium can affect thyroid function, potentially leading to hypothyroidism.

D. Hemoglobin - While hemoglobin levels may be monitored during lithium therapy, they are not typically assessed prior to initiating treatment.
