A nurse is assessing a client who has heart failure and a new prescription for metoprolol. Which of the following findings should the nurse identify as an adverse effect of the medication?

Choice A reason: Asking if the client feels like they have food stuck at the base of their throat is a pertinent question for assessing swallowing in a client with oral achalasia. Achalasia is characterized by difficulty in swallowing due to the inability of the lower esophageal sphincter to relax, leading to a sensation of food being stuck.

Choice B reason: While burning sensations in the throat can be associated with gastroesophageal reflux disease (GERD), they are not specific to achalasia. However, some clients with achalasia may experience similar symptoms due to food stasis and fermentation in the esophagus.

Choice C reason: Feelings of fullness in the neck are not a typical symptom of achalasia. Achalasia primarily affects the esophagus and does not usually cause a sensation of fullness in the neck.

Choice D reason: Pain while swallowing, or odynophagia, can occur in achalasia but is more commonly associated with conditions that cause inflammation or irritation of the esophagus, such as infections or ingestion of irritants.

Choice A reason: The fluctuation of fluid in the water-seal chamber does not necessarily mean that the lung is fully re-expanded. The water-seal chamber's fluid level fluctuates with the client's breathing because it reflects the changes in intrathoracic pressure.

Choice B reason: The statement "Your breathing pattern causes this" is correct. The fluctuation, also known as tidaling, in the water-seal chamber is normal and occurs in response to the client's breathing. When the client inhales, negative pressure in the chest cavity causes the fluid level to rise, and when the client exhales, the pressure becomes positive, causing the fluid level to fall.

Choice C reason: Suction pressure that is too high can cause continuous bubbling in the suction control chamber but does not directly cause the fluid in the water-seal chamber to rise and fall. The suction control chamber's bubbling should be steady and gentle when the suction is set correctly.

Choice D reason: Continuous bubbling in the water-seal chamber may indicate an air leak, which is a problem that needs to be addressed. However, normal fluctuation with breathing is not indicative of an air leak.
