When developing the plan of care for a client who is receiving lithium therapy, which nursing diagnosis would the nurse most likely identify as a priority? A) Self-Care Deficit B) Disturbed Sleep Pattern C) Imbalanced Nutrition: Less Than Body Requirements D) Imbalanced Fluid Volume

Ans: D Feedback: Fluid balance determines the concentration of lithium in the blood and thus the client's risk for toxicity. Therefore, imbalanced fluid volume is a priority. Self-care deficit, disturbed sleep pattern, and imbalanced nutrition also may apply, but imbalanced fluid volume would be the priority

A nurse is caring for a client who has been prescribed a monoamine oxidase inhibitor (MAOI). Which of the following should the nurse instruct the client to avoid? A) Milk B) Butter C) Rice D) Yogurt

Ans: D Feedback: The nurse should ask the client to avoid yogurt because yogurt contains tyramine, which interacts with MAOIs and causes hypertensive crisis. Milk, butter, and rice do not contain tyramine and hence can be consumed when the client is undergoing treatment with MAOIs.

A nurse is caring for an older adult client who has been prescribed amoxapine for depression accompanied by anxiety. After administration of the drug, the nurse observes muscle rigidity and sweating. The nurse identifies these as the symptoms of neuroleptic malignant syndrome. Which of the following would the nurse do next? A) Suggest the client engage in exercise. B) Get the client to drink a glass of cold water. C) Encourage the client to breathe deeply. D) Stop the drug and contact the physician
