A student nurse is observing a patient with cataracts sitting very close to the television. What alteration would the student nurse suspect that is causing this patient's behavior?
Altered Impulse translation
Altered nerve impulse conduction
Altered stimulation
Altered sensory reception
The Correct Answer is D
A. Altered Impulse translation: Impulse translation refers to the processing and interpretation of sensory input by the brain. While cataracts affect vision, the primary problem is not with brain interpretation but with how light reaches the retina, making this option less directly related to the patient’s behavior.
B. Altered nerve impulse conduction: Nerve impulse conduction involves the transmission of signals along nerves. In cataracts, the optic nerve and neural pathways are typically intact; the issue lies in light obstruction from the lens opacity rather than impaired conduction of impulses.
C. Altered stimulation: Altered stimulation would suggest that the environment is insufficiently stimulating the senses. However, the patient’s behavior, sitting close to the television, indicates a compensatory response to difficulty seeing, not a lack of environmental stimulation.
D. Altered sensory reception: Cataracts cause clouding of the lens, reducing the eye’s ability to receive and focus light properly, which directly affects visual sensory reception. Sitting close to the television is a compensatory behavior to improve visual input, reflecting the impact of altered sensory reception on functional activity.

Correct Answer is B
Explanation
A. Keep the door open during the night: Keeping the door open increases environmental noise and visual stimulation from the hallway or unit activity. This approach would likely worsen sleep disruption and agitation rather than promote rest, making it an inappropriate intervention for managing sensory overload.
B. Provide the patient with earplugs: Earplugs reduce auditory stimulation from alarms and ambient noise, promoting sleep and reducing agitation in a high-stimulation environment. For patients in critical care or telemetry units, mitigating sensory overload through non-pharmacologic interventions like earplugs is safe, effective, and preserves monitoring while addressing patient comfort and sleep quality.
C. Administer an opioid medication to help the patient sleep: Opioids are primarily indicated for pain management, not for promoting sleep. Using opioids to induce sleep can lead to respiratory depression, sedation, and other complications, especially in older adults or those with comorbidities, making this unsafe for managing environmental noise.
D. Turn off the monitors at night: Disabling monitoring equipment compromises patient safety and violates hospital protocols, as continuous monitoring is essential for detecting critical changes in vital signs. This is never appropriate as a method to reduce environmental noise, regardless of patient discomfort.
Correct Answer is B
Explanation
Calculation:
- Identify the given time in 24-hour format
Given time: 2100
- Convert to 12-hour format
Since 2100 is greater than 1200, subtract 1200 to convert to PM time: 2100 − 1200 = 900
- Add the colon and AM/PM notation
= 9:00 pm
