A nurse is assisting with the admission of an older adult client. Which of the following subjective findings suggests that the client may have cataracts?

Answer: B. Compare the result with the baseline reading

Rationale:

A. Check the client's heart rate on the oximeter:
Although checking the heart rate may provide context for assessing the client's overall status, it does not address the primary concern of the low oxygen saturation. Understanding the client's baseline saturation level takes priority to guide further actions effectively.

B. Compare the result with the baseline reading:
Comparing the reading with the client's baseline is essential. For clients with chronic respiratory conditions, baseline oxygen levels may naturally be lower. Identifying if this 88% saturation is typical or unusual for the client helps determine the need for further intervention or adjustment.

C. Decrease the amount of oxygen administered:
Reducing oxygen flow when the saturation is low is contraindicated, as it could worsen hypoxia. Instead, increasing oxygen may be warranted if the reading remains below the baseline after further assessment.

D. Perform another reading while the client ambulates:
Repeating the reading during ambulation may worsen hypoxia and is not ideal without understanding baseline oxygenation at rest. Re-evaluation at rest or in a different position may be more appropriate for accurate assessment.

c. Hallucination

In the scenario described, the client's experience of receiving special audible messages from the Central Intelligence Agency that no one else can hear indicates a hallucination. Hallucinations are perceptual disturbances in which a person experiences sensory perceptions without any external stimuli. They can occur in any sensory modality, such as hearing (auditory hallucinations), seeing (visual hallucinations), smelling (olfactory hallucinations), tasting (gustatory hallucinations), or feeling (tactile hallucinations).

In this case, the client is experiencing auditory hallucinations, as he is perceiving auditory stimuli (audible messages) that are not present in the external environment. Auditory hallucinations are most commonly associated with schizophrenia, although they can occur in other psychiatric disorders as well.

Derealization (option a) refers to a subjective feeling of unreality or detachment from the environment. It involves a perception that the external world is strange, distorted, or unreal. This is not the primary alteration in perception described in the scenario.

Illusion (option b) is a misinterpretation or misperception of a real sensory stimulus. It occurs when a person's perception of an actual stimulus is distorted or misunderstood. There is no indication of a misperception of a real stimulus in the scenario.

Depersonalization (option d) is a subjective experience of being detached from one's own body, thoughts, or emotions. It involves a feeling of being outside of oneself or observing oneself from a distance. This is not the primary alteration in perception described in the scenario.

Therefore, the correct answer is c. Hallucination, as the client's experience of receiving special audible messages that no one else can hear represents an auditory hallucination.
