During assessment, the nurse would expect which part of the body to indicate central cyanosis in a client with a severe asthma attack?

A. To prevent further dehydration:

While preventing dehydration is important, it is not the primary reason for bringing a cup of water when assessing the thyroid gland. Dehydration is addressed through overall fluid management rather than during a specific thyroid exam.

B. To assist the client to feel more comfortable:

Providing comfort is essential, but bringing a cup of water specifically for comfort during a thyroid exam is not typically necessary. The primary focus of the water in this context is related to the assessment process.

C. To observe the movement of the thyroid gland:

Observing the movement of the thyroid gland during swallowing can help the nurse assess for abnormalities. Having the client drink water allows the nurse to observe the thyroid gland's movement, which can indicate the presence of goiters, nodules, or other irregularities.

D. To promote the nurse-client relationship:

Promoting a good nurse-client relationship is always beneficial, but bringing a cup of water for this specific purpose is not relevant to the physical assessment of the thyroid gland. The water's main purpose is to facilitate the physical examination process.

A) Color discrimination:

Color discrimination involves assessing the client's ability to differentiate between various colors, typically using color plates like the Ishihara test. This test is often used to detect color blindness or deficiencies in color vision. The action depicted in the image, which involves reading text up close, is not relevant to assessing color vision capabilities.

B) Near vision:

Near vision is assessed by having the client read small text or print held at a close distance, often using a near vision chart or card. The image shows the client covering one eye with an occluder while reading text, which is a common method to test the clarity and focus of near vision. This helps determine if the client has issues such as presbyopia, which affects near vision acuity.

C) Distance vision:

Distance vision is typically evaluated using a Snellen chart, where the client reads letters or symbols from a distance of 20 feet. The test aims to assess the clarity of vision at a distance. The action in the image does not align with this type of assessment, as it focuses on close-up reading rather than distance.

D) Intraocular pressure:

Intraocular pressure is measured using tools like a tonometer to assess the fluid pressure inside the eye, which is crucial for diagnosing conditions like glaucoma. This test involves specific instruments and procedures, unlike the reading task depicted in the image, which is unrelated to measuring eye pressure.
