A nurse is providing teaching for a client who has binge-eating disorder and is morbidly obese. The client has been prescribed orlistat. Which of the following statements indicates to the nurse that the client understands the teaching?

A. The client runs 4 miles outdoors every afternoon: Exercise, especially in hot weather, can lead to dehydration and increased sweating, which can result in decreased lithium excretion and increased lithium levels in the blood, leading to toxicity. Therefore, this factor puts the client at risk for lithium toxicity.
B. The client eats 2 to 3 g of sodium-containing foods: Sodium intake can affect lithium levels, as high sodium levels can increase lithium excretion and lower lithium levels. Therefore, eating sodium-containing foods is less likely to contribute to lithium toxicity.
C. The client eats foods high in tyramine: Tyramine-rich foods can interact with certain medications, such as MAOIs, but they do not directly increase the risk of lithium toxicity.
D. The client drinks 2 liters of liquids daily: Adequate hydration is important for clients taking lithium, as dehydration can increase lithium levels. Therefore, drinking 2 liters of liquids daily is not a risk factor for lithium toxicity.

A. Increase hematocrit: Fluid overload typically leads to hemodilution, resulting in a decrease in hematocrit rather than an increase. Therefore, an increase in hematocrit would not be expected in a client with fluid overload.
B. Increased temperature: Fluid overload is not typically associated with an increased body temperature. Instead, fever may indicate an infection or another underlying cause. Therefore, an increased temperature would not be a typical finding in a client with fluid overload.
C. Increased heart rate: Fluid overload can lead to an increased heart rate as the body attempts to maintain adequate cardiac output in the presence of excess fluid volume. An elevated heart rate is a compensatory mechanism to maintain tissue perfusion despite the increased workload on the heart.
D. Increased respiratory rate: Fluid overload can cause pulmonary congestion, leading to increased respiratory effort and a higher respiratory rate as the body attempts to compensate for decreased gas exchange efficiency. An increased respiratory rate helps to improve oxygenation and remove excess carbon dioxide from the body.
E. Increased blood pressure: Fluid overload often leads to increased blood pressure due to the increased volume of circulating blood, which can strain the cardiovascular system. Elevated blood pressure is a common manifestation of fluid overload and reflects the increased workload on the heart and blood vessels.
