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.
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 C
Explanation
Choice A Reason:
Excoriation is incorrect. Excoriation refers to scratch marks or abrasions on the skin caused by scratching or rubbing. While excoriation can occur as a result of scratching due to itching caused by an allergic reaction, it is not a specific characteristic of an allergic reaction to an insect bite. However, it may develop secondary to the itching associated with insect bites.
Choice B Reason:
Papules are incorrect. Papules are small, raised bumps on the skin that can have various causes, including insect bites. While papules can sometimes accompany an allergic reaction to insect bites, they are not as characteristic as wheals (hives) in such reactions. Papules may also represent other skin conditions or reactions, so they are not as specific to allergic reactions as wheals.
Choice C Reason:
Wheals are correct. Wheals, also known as hives or urticaria, are raised, red, itchy areas of the skin that often occur as part of an allergic reaction to insect bites, medications, foods, or other allergens. Wheals are typically transient and can vary in size and shape. Excoriation (choice A) refers to scratch marks or abrasions on the skin caused by scratching or rubbing.
Choice D Reason:
Fissuring is incorrect. Fissuring refers to deep cracks or splits in the skin's surface. Fissures are not typically associated with allergic reactions to insect bites. Instead, they may occur in conditions such as eczema, psoriasis, or severe dry skin. Therefore, while skin fissuring may occur in some skin conditions, it is not a typical finding in allergic reactions to insect bites.
Correct Answer is C
Explanation
Choice A Reason:
History of a fractured patella is incorrect. While a history of a fractured patella may lead to some degree of crepitation in the knee joint, especially if there was damage to the articular surfaces during the injury, it is less likely to cause widespread crepitation with joint movement. Crepitation associated with a fractured patella would typically be localized to the site of injury rather than throughout the joint.
Choice B Reason:
Knee arthroplasty surgery is incorrect. Knee arthroplasty surgery involves the replacement of a damaged knee joint with an artificial prosthesis. While crepitation can occur in some cases following knee arthroplasty, it is less likely to be the cause of crepitation observed in this scenario, especially if the client's knee arthroplasty was successful and without complications.
Choice C Reason:
Degenerative disease is correct. Degenerative disease of the knee joint, such as osteoarthritis, is a common cause of crepitation during joint movement. Osteoarthritis is characterized by the breakdown of cartilage in the joints, leading to friction between bones and resulting in crepitus. This condition is often associated with aging, repetitive stress on the joints, or underlying joint abnormalities.
Choice D Reason:
Needle aspiration of the synovial space is incorrect. Needle aspiration of the synovial space is a procedure performed to remove excess fluid or to obtain a sample of synovial fluid for diagnostic purposes. While this procedure may be performed for various reasons, it is not directly associated with crepitation in the knee joint.
