A nurse is caring for a client who has myasthenia gravis. The nurse should recognize that this disease is caused by which of the following types of hypersensitivities?

Frothy sputum is a sign of left-sided heart failure, due to the pulmonary congestion and impaired gas exchange. The sputum may be pink-tinged or blood-streaked, indicating pulmonary edema.

a. Dependent edema is more likely to be seen in clients who have right-sided heart failure, due to the increased venous pressure and fluid retention. The edema is usually symmetrical and affects the lower extremities, abdomen, and sometimes the face.

c. Nocturnal polyuria is not a specific finding of left-sided heart failure, but it may occur in clients who have renal impairment, diabetes mellitus, or diuretic therapy.

d. Jugular distention is another sign of right-sided heart failure, due to the increased central venous pressure and backward flow of blood into the superior vena cava. It is visible as a bulging of the neck veins, especially when the client is in a semi-Fowler's position.

Aphasia is a language disorder that affects the ability to understand or produce speech. It can be caused by damage to the brain regions that control language, such as from a stroke. Depending on the type and severity of aphasia, the client may have difficulty with comprehension, expression, reading, or writing. Communication strategies for clients with aphasia include using nonverbal cues, such as gestures, facial expressions, pictures, or objects, to supplement verbal messages and enhance understanding.

The other options are not correct because:

a. "Use simple, childlike statements when speaking." This statement is incorrect because it is patronizing and disrespectful to the client. The client's cognitive and intellectual abilities are not affected by aphasia, only their language skills. The nurse should use simple and clear sentences, but not childish or demeaning ones.

c. "Use a higher-pitched tone of voice when speaking." This statement is incorrect because it is unnecessary and may be irritating to the client. The client's hearing is not affected by aphasia, only their language processing. The nurse should use a normal tone of voice and speak slowly and clearly.

d. "Ask multiple choice questions as part of the conversation." This statement is incorrect because it may be confusing and frustrating to the client. The client may have difficulty with verbal output or comprehension, and

multiple choice questions may add to their cognitive load. The nurse should ask yes or no questions or use gestures or pictures to elicit responses from the client.
