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 D

Explanation

Choice A Reason:
Normal mental status for age is incorrect. This choice would not be the most accurate conclusion based on the client's response. While it's possible that the client's response could be influenced by factors such as cultural background or personal interpretation, the inability to understand the metaphorical meaning of a commonly known proverb might suggest some level of cognitive impairment or difficulty with abstract thinking. Therefore, it would be premature to conclude that the client's response reflects a normal mental status for her age.
Choice B Reason:
Impaired concentration is incorrect. Impaired concentration would manifest as difficulty maintaining focus our attention during the interaction. However, the client's response doesn't suggest a lack of attention or focus. Instead, it indicates a misinterpretation of the proverb, which is more indicative of impaired thinking or difficulty understanding abstract concepts rather than impaired concentration.
Choice C Reason:
Impaired memory is incorrect. Impaired memory would typically involve difficulty recalling information or events from the past. In this scenario, the client is able to recall the phrase "Glass Houses" but demonstrates difficulty understanding its meaning. Therefore, impaired memory is not the most appropriate conclusion based on the client's response. Instead, the response suggests impaired thinking or difficulty with abstract reasoning.
Choice D Reason:
Impaired thinking is correct. The client's response indicates difficulty understanding the metaphorical meaning of the proverb "Glass Houses," which typically implies that those who live in fragile or vulnerable situations should avoid criticizing others, as they themselves are also vulnerable to criticism or judgment. Instead, the client's response focuses on the literal interpretation of the phrase, suggesting impaired thinking or difficulty grasping abstract concepts.

A. Have the client lay flat while listening to the anterior surface of the chest. B. Use the bell of the stethoscope to listen to the lung fields over lower lobes. C. Shave all chest hair that may distort sounds heard through the diaphragm. D. Press the stethoscope's diaphragm firmly on the skin over each lung field.

Correct Answer is D

Explanation

Choice A Reason:
Having the client lay flat while listening to the anterior surface of the chest is incorrect because having the client lay flat may not be the most optimal position for auscultating lung sounds. While auscultation of the anterior surface of the chest is important, particularly for assessing the upper lobes of the lungs, having the client lay flat may not provide the best positioning for detecting all lung sounds, especially those located in the posterior lung fields.
Choice B Reason:
Using the bell of the stethoscope to listen to the lung fields over lower lobes is incorrect because using the bell of the stethoscope is more suitable for detecting low-frequency sounds such as heart murmurs or bruits. Adventitious lung sounds, such as crackles (rales) or wheezes, are typically high-pitched sounds that are best heard using the diaphragm of the stethoscope. Therefore, using the bell may not be the most effective technique for assessing adventitious lung sounds.
Choice C Reason:
Shaving all chest hair that may distort sounds heard through the diaphragm is incorrect because while removing chest hair may improve sound transmission for certain auscultatory findings, such as heart sounds, it is not specifically indicated for assessing adventitious lung sounds. Chest hair removal is not necessary for auscultation of lung sounds with the diaphragm of the stethoscope, as the sound transmission through chest hair is minimal and unlikely to significantly distort lung sounds.
Choice D Reason:
Pressing the stethoscope's diaphragm firmly on the skin over each lung field is correct because using the diaphragm of the stethoscope and pressing it firmly on the skin over each lung field ensures good contact with the chest wall, allowing for optimal transmission of lung sounds. Adventitious lung sounds, such as crackles or wheezes, are best heard using the diaphragm, particularly when it is applied firmly to the chest wall to minimize external noise and enhance sound transmission. Therefore, this technique is the most appropriate for assessing adventitious lung sounds during auscultation.
