A client with hypertension reports experiencing blurred vision intermittently over the last few weeks. What should the nurse explain to the client?

Choice a reason:
Placing the client on 2L via nasal cannula is a common intervention for hypoxemia, but with the client's pulse oximetry at 88%, which is below the normal range of 95-100%, and the presence of tachypnea, a more immediate assessment of the client's respiratory status is warranted. Oxygen therapy should be guided by the results of arterial blood gas (ABG) analysis to tailor the treatment to the client's specific needs.

Choice b reason:
Obtaining a blood glucose level is not the most immediate concern in the context of altered mental status and respiratory distress. While it is important to rule out hypoglycemia as a cause of altered mental status, the primary concern indicated by the vital signs is the client's respiratory condition.

Choice c reason:
Calling the physician for an order for a stat arterial blood gas is the most appropriate action. The ABG will provide detailed information about the client's oxygenation, carbon dioxide levels, and acid-base balance. This is crucial for a client with a new onset change in mental status and tachypnea, as it can indicate respiratory failure or other serious complications of pneumonia.

Choice d reason:
Requesting an order for lorazepam is not appropriate given the client's current respiratory status. Lorazepam, a benzodiazepine, can depress the central nervous system and respiratory drive, potentially worsening the client's hypoxemia and respiratory effort.

Choice A Reason:
Bright lighting can be overwhelming for clients experiencing perceptual alterations. While regular checks on the client's mental status are important, excessive brightness can exacerbate sensory overload. The goal is to create an environment that is calming and reduces sensory stimuli to manageable levels.

Choice B Reason:
Keeping the lights dim may help to soothe some clients, but continuous noise from a radio can contribute to sensory overload. It's crucial to tailor the environment to the individual needs of the client, which often means providing a quiet space with minimal auditory distractions.

Choice C Reason:
Having the client sit by the nurse's desk may provide necessary supervision, but it can also expose the client to high levels of activity and noise, which can be disorienting. Rest periods with the television on can be distracting and may not offer the tranquil environment needed for a client with perceptual alterations.

Choice D Reason:
Providing a well-lit room without glare or shadows and limiting noise is the most appropriate environmental change for a client with perceptual alterations. This approach helps to reduce the risk of misperceptions and hallucinations, which can be triggered by shadows and glare. A quiet and well-lit environment supports better sensory processing and helps to maintain orientation.
