A nurse is caring for a client who has depression and reports only sleeping a few hours each night. Which of the following instructions should the nurse give the client to promote sleep?

A. Monitoring liver enzymes (AST, ALT) is typically not directly related to lithium therapy. Elevated liver enzymes may indicate liver damage from various causes, such as hepatitis or medication toxicity, but it is not a routine monitoring parameter for lithium.
B. Lithium can decrease the excretion of uric acid, potentially leading to elevated levels. Monitoring uric acid levels helps to detect hyperuricemia, which may contribute to conditions like gout. It's important to monitor this parameter periodically during lithium therapy.
C. ESR is a nonspecific marker of inflammation and is not specifically monitored in relation to lithium therapy. It is used to diagnose or monitor conditions like infections, autoimmune diseases, or certain cancers, but it does not directly relate to lithium use.
D. Monitoring serum sodium levels is crucial during lithium therapy because lithium can affect renal function and electrolyte balance, including sodium levels. Hyponatremia is a potential adverse effect of lithium, and regular monitoring helps detect and manage this condition promptly.

A. This statement indicates that the client has abstained from alcohol while on haloperidol decanoate. This is a positive statement and shows compliance with recommendations, as alcohol can interact with medications and affect their effectiveness or cause adverse reactions. There is no immediate concern with this statement.
B. Haloperidol can increase sensitivity to sunlight (photosensitivity). Spending several hours outside gardening in the sun could potentially increase the risk of sunburn or other skin reactions due to photosensitivity. The nurse should address this statement by educating the client about the need to use sunscreen, wear protective clothing, and avoid prolonged sun exposure, especially during peak sunlight hours.
C. Regular monitoring of blood pressure is generally recommended for clients taking haloperidol, as it can occasionally cause hypotension (low blood pressure) as a side effect. Checking blood pressure once a week is a reasonable frequency, but the nurse should ensure that the client understands the signs and symptoms of hypotension and knows when to seek medical attention if blood pressure readings are abnormal.
D. Chewing sugar-free gum is generally not contraindicated while taking haloperidol. However, if the gum contains caffeine or other stimulants, it could potentially exacerbate certain side effects of the medication, such as tremors or restlessness. The nurse should inquire further about the type of gum being used and educate the client about potential interactions or side effects.
