The nurse asks the client to perform the action pictured. What is the nurse assessing?
Color discrimination
Near vision
Distance vision
Intraocular pressure
The Correct Answer is B
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.

Correct Answer is C
Explanation
A) Intercostal spaces:
Assessing intercostal spaces typically involves palpating or inspecting the area between the ribs to check for abnormalities such as retractions or tenderness, usually conducted with the client sitting or standing.
B) Lymph nodes:
Palpation of lymph nodes, such as in the cervical region, involves using fingertips to gently feel for enlarged or tender nodes. This examination focuses on areas like the neck, underarms, and groin.
C) Skin Turgor:
The image depicts a nurse pinching the skin, likely on the chest or forearm, which is a common method to assess skin turgor. Skin turgor evaluation helps determine hydration status; if the skin remains tented and returns slowly to its original position, it indicates dehydration.
D) Carotid Pulse:
Assessing the carotid pulse involves palpating the carotid artery along the side of the neck to evaluate the strength and rhythm of the pulse. This is typically done using the pads of the fingers, not by pinching the skin.
Correct Answer is C
Explanation
A. Acanthosis Nigricans:
Acanthosis nigricans is characterized by dark, velvety patches of skin, often found in body folds such as the neck, armpits, and groin. It does not present as the yellow discoloration seen in the photo.
B. Cyanosis:
Cyanosis is a bluish discoloration of the skin and mucous membranes due to inadequate oxygenation of the blood. The image shows yellow discoloration, not the blue tint associated with cyanosis.
C. Jaundice:
Jaundice is indicated by a yellowish tint to the skin and sclera due to elevated bilirubin levels, commonly associated with liver dysfunction. The photo clearly shows this yellow discoloration, consistent with jaundice, often seen in chronic alcoholics with liver disease.
D. Carotenemia:
Carotenemia presents as a yellow-orange discoloration of the skin, especially on the palms and soles, due to high levels of carotene in the blood. It does not typically affect the sclera, which differentiates it from jaundice. The uniform yellowing of the skin and eyes in the photo aligns more with jaundice.
