To assess a client's pupillary reaction to accommodation, what action should the nurse take?

Observe pupil size when focusing on a near object and then a far object.

Compare the shape of each of the pupils bilaterally with normal room light.

Note the speed of pupil constriction when a penlight is shined into the eye.

Determine if dilation of the pupils occurs when the room is darkened.

Answer and Explanation

The Correct Answer is A

Choice A Reason:
Observing pupil size when focusing on a near object and then a far object is correct. This choice is correct because it directly assesses the pupillary reaction to accommodation, which refers to the changes in pupil size that occur when the eyes shift focus between near and far objects. Observing the pupils while the client focuses on a near object and then a far object allows the nurse to assess how the pupils constrict (become smaller) or dilate (become larger) in response to changes in focus, providing valuable information about the client's accommodation reflex.
Choice B Reason:
Comparing the shape of each of the pupils bilaterally with normal room light is incorrect. While comparing the shape of each pupil bilaterally with normal room light is a valid assessment technique for evaluating pupillary size and symmetry, it does not specifically assess the pupillary reaction to accommodation. Therefore, this choice is not as directly relevant to assessing accommodation reflex as choice A.
Choice C Reason:
Noting the speed of pupil constriction when a penlight is shined into the eye is incorrect. This choice refers to assessing the pupillary light reflex, which involves observing the speed and extent of pupil constriction in response to a bright light stimulus. While this assessment is important for evaluating the pupillary response to light, it does not specifically assess accommodation, which involves changes in pupil size in response to changes in focus between near and far objects. Therefore, this choice is not directly relevant to assessing accommodation reflex.
Choice D Reason:
Determining if dilation of the pupils occurs when the room is darkened is incorrect. This choice involves assessing the pupillary response to changes in ambient light levels, which is known as the pupillary light reflex. While assessing pupil dilation in response to darkness is important for evaluating the pupillary response to changes in light, it does not specifically assess accommodation reflex. Therefore, this choice is not directly relevant to assessing accommodation reflex.

Correct Answer is B

Explanation

Choice A Reason:
Coronary heart disease is incorrect. Coronary heart disease is primarily associated with cardiovascular symptoms such as chest pain, shortness of breath, and fatigue. While some nail changes may occur in individuals with coronary heart disease due to decreased oxygenation, brittle, concave nails are not a typical manifestation of this condition. Therefore, this option is less likely to explain the appearance of the nails.
Choice B Reason:
Iron deficiency anemia is correct. Iron deficiency anemia is characterized by a lack of iron in the body, leading to decreased production of hemoglobin and red blood cells. One of the classic nail findings associated with iron deficiency anemia is koilonychia, which presents as brittle, concave nails with a spoon-like appearance. This is due to structural changes in the nails caused by the deficiency of iron. Therefore, this option is the most likely explanation for the observed nail changes.
Choice C Reason:
Diabetes mellitus is incorrect. Diabetes mellitus can lead to various dermatologic manifestations, including nail changes such as thickening, discoloration, and slow nail growth. However, brittle, concave nails with a spoon-like appearance are not typically associated with diabetes mellitus. Therefore, while diabetes mellitus may affect the nails, it is less likely to explain the specific appearance observed in this case.
Choice D Reason:
Recent candida infection is incorrect. Candida infections, particularly in the nail folds (paronychia), can lead to changes in the nails such as discoloration, thickening, or separation from the nail bed. However, brittle, concave nails with a spoon-like appearance are not typical findings of candida infections. Therefore, while recent candida infection may affect the nails, it is less likely to explain the specific appearance observed in this case.

A. Hyperextension and palmar flexion. B. Plantar flexion. C. Forearm pronation. D. Forearm supination.

Correct Answer is A

Explanation

Choice A Reason:
Hyperextension and palmar flexion are correct. Hyperextension involves moving the wrist joint backward, testing its ability to extend beyond its neutral position. Palmar flexion involves moving the wrist joint forward, testing its ability to flex toward the palm. These movements collectively assess the range of motion of the wrist joint in both directions, which is essential for identifying any limitations or pain associated with certain movements. Since the client presents with right wrist pain and ecchymosis, assessing both hyperextension and palmar flexion can help determine if there's any injury or impairment affecting the wrist's mobility.
Choice B Reason:
Plantar flexion is incorrect. Plantar flexion refers to a movement of the foot and ankle, not the wrist. Therefore, instructing the client to perform plantar flexion would not assess the wrist's mobility and is not relevant to the presented scenario of right wrist pain with ecchymosis.
Choice C Reason:
Forearm pronation is incorrect. Forearm pronation involves rotating the forearm so that the palm faces downward. This movement primarily assesses the pronation and supination of the forearm, not the wrist's mobility. Since the client's symptoms are specific to the wrist, assessing forearm pronation would not directly evaluate the wrist's range of motion.
Choice D Reason:
Forearm supination is incorrect. Forearm supination involves rotating the forearm so that the palm faces upward. Similar to forearm pronation, this movement primarily assesses the forearm's mobility, not the wrist's mobility. Therefore, instructing the client to perform forearm supination would not be an appropriate method for assessing the wrist's range of motion in the context of right wrist pain with ecchymosis.
