A nurse is reinforcing teaching with a client who is at risk for hypokalemia. The nurse should instruct the client that which of the following foods is the best source of potassium?

Choice A reason: Shaking the inhaler well before using it is a correct action for the client to take, as it helps to mix the medication and the propellant. However, it is not the best answer, as it is a general instruction that applies to most inhalers, not a specific one that indicates an understanding of the teaching.

Choice B reason: Holding the breath for 10 seconds after inhaling the medication is a correct action for the client to take, as it helps to keep the medication in the lungs and improve its absorption. However, it is not the best answer, as it is a general instruction that applies to most inhalers, not a specific one that indicates an understanding of the teaching.

Choice C reason: Rinsing the mouth with water after using the inhaler is the best answer, as it indicates an understanding of the teaching. Rinsing the mouth with water helps to prevent oral thrush, a fungal infection that can occur as a side effect of some inhalers, especially those that contain steroids.

Choice D reason: Waiting 30 seconds between each puff of the inhaler is not a correct action for the client to take, as it can reduce the effectiveness of the medication. The client should wait at least one minute between each puff of the inhaler, unless instructed otherwise by the provider.

Choice A reason: Tachycardia is a sign of circulatory overload. Circulatory overload is a condition where the blood volume or rate of infusion is too high for the client's cardiovascular system. This causes the heart to beat faster and harder to pump the excess fluid, resulting in a high heart rate, or tachycardia.

Choice B reason: Weight loss is not a sign of circulatory overload. Weight loss is a condition where the body loses more calories than it consumes, resulting in a decrease in body mass. Weight loss can be caused by various factors, such as diet, exercise, illness, or medication. Weight gain, not weight loss, is a sign of circulatory overload, as the excess fluid accumulates in the body.

Choice C reason: Hypotension is not a sign of circulatory overload. Hypotension is a condition where the blood pressure is too low, which can impair the blood flow to the vital organs. Hypotension can be caused by various factors, such as dehydration, bleeding, shock, or medication. Hypertension, not hypotension, is a sign of circulatory overload, as the excess fluid increases the pressure in the blood vessels.

Choice D reason: Diaphoresis is not a sign of circulatory overload. Diaphoresis is a condition where the body sweats excessively, which can help to regulate the body temperature and eliminate toxins. Diaphoresis can be caused by various factors, such as fever, anxiety, exercise, or medication. Edema, not diaphoresis, is a sign of circulatory overload, as the excess fluid leaks into the interstitial spaces and causes swelling.
