A nurse is caring for a client 1 day postoperative who has developed atelectasis. Which of the following manifestations is an expected finding for this condition?

Hypoxemia

Apnea

Pleural effusion

Dysphagia

Answer and Explanation

The Correct Answer is A

A) Hypoxemia:
This is the correct answer. Atelectasis, which is the collapse or incomplete inflation of the lung, can lead to impaired gas exchange and subsequent hypoxemia. As lung volume decreases due to collapse, ventilation-perfusion (V/Q) mismatch occurs, resulting in decreased oxygenation of arterial blood. Hypoxemia is a common finding in individuals with atelectasis and may manifest as decreased oxygen saturation levels on pulse oximetry or arterial blood gas analysis.

B) Apnea:
Apnea, defined as the cessation of breathing, is not typically associated with atelectasis. While atelectasis can contribute to respiratory compromise and may result in respiratory distress, including tachypnea or increased work of breathing, it does not usually lead to complete cessation of breathing.

C) Pleural effusion:
A pleural effusion is the accumulation of fluid in the pleural space surrounding the lungs. While pleural effusion may occur concurrently with atelectasis, it is not an expected finding specifically associated with atelectasis itself. Pleural effusion may cause respiratory symptoms such as dyspnea or chest pain but is not a primary manifestation of atelectasis.

D) Dysphagia:
Dysphagia, or difficulty swallowing, is unrelated to atelectasis. While dysphagia can occur as a result of various conditions affecting the esophagus or neurological control of swallowing, it is not a typical manifestation of atelectasis. Atelectasis primarily affects the lungs and respiratory function rather than swallowing function.

Correct Answer is ["B","C","E"]

Explanation

A) Hypoglycemia:
Propranolol, a nonselective beta-blocking agent, can mask some of the symptoms of hypoglycemia, such as tachycardia and tremors, by blocking the sympathetic response. Therefore, it is not typically used in the treatment of hypoglycemia and may even exacerbate low blood sugar levels.

B) Arrhythmias:
Propranolol is commonly used in the treatment of various cardiac arrhythmias. By blocking beta-adrenergic receptors in the heart, it reduces the heart rate and myocardial contractility, thereby helping to control arrhythmias such as atrial fibrillation and ventricular tachycardia.

C) Hypertension:
Propranolol is effective in lowering blood pressure and is often prescribed for the management of hypertension. Its beta-blocking action reduces cardiac output and suppresses renin release, leading to decreased systemic vascular resistance and blood pressure.

D) Hypokalemia:
Propranolol does not have a direct role in the treatment of hypokalemia. While it can potentially exacerbate hypokalemia through its effects on potassium metabolism, it is not a primary treatment for this electrolyte imbalance.

E) Angina:
Propranolol is indicated for the treatment of angina pectoris, particularly in cases of stable angina. By reducing myocardial oxygen demand through its negative chronotropic and inotropic effects, it helps relieve anginal symptoms and improve exercise tolerance."

A. Glaucoma B. Depression C. Asthma D. Migraines

Correct Answer is C

Explanation

A) Glaucoma:
While propranolol can exacerbate symptoms of glaucoma, it is not an absolute contraindication. However, caution is warranted in clients with glaucoma due to its potential to increase intraocular pressure.

B) Depression:
Propranolol is not contraindicated in clients with a history of depression. In fact, it is sometimes used to manage anxiety symptoms associated with certain types of depression.

C) Asthma:
Propranolol is contraindicated in clients with a history of asthma or bronchospasm because it can exacerbate bronchoconstriction and potentially precipitate an acute asthma attack.

D) Migraines:
Propranolol is often used prophylactically in clients with migraines to reduce the frequency and severity of attacks. It is not contraindicated in clients with a history of migraines."
