nurse is reinforcing teaching with a client who has a new prescription for phenytoin. The nurse should recognize that which of the following statements by the client indicates a need for further teaching?

a. Increasing dyspnea: Atelectasis is the collapse of alveoli, leading to decreased lung volume and impaired gas exchange. Dyspnea (difficulty breathing) is a common symptom as the lung's ability to oxygenate the blood is compromised.

b. Dry cough: A dry cough may be present, but it is not specific to atelectasis. It can occur for various reasons postoperatively.

c. Facial flushing: Facial flushing is not a typical finding in atelectasis. It is more commonly associated with conditions such as fever or allergic reactions.

d. Decreasing respiratory rate: Atelectasis can lead to increased respiratory rate as the body tries to compensate for decreased lung function. A decreasing respiratory rate would be less likely in the presence of atelectasis.

a. Decreased calcium level: NG tube drainage is more likely to result in hypokalemia (decreased potassium) than hypocalcemia (decreased calcium).

b. Decreased potassium level: NG tube drainage, which contains stomach contents, can lead to loss of potassium. Monitoring for hypokalemia is crucial as it can result in cardiac dysrhythmias.

c. Elevated magnesium level: NG tube drainage is not typically associated with an increase in magnesium levels.

d. Elevated sodium level: NG tube drainage may contribute to sodium loss, leading to hyponatremia, rather than hypernatremia.
