Rationale for Choice A:

Arranging for a bedside commode can be helpful for patients who have difficulty ambulating to the bathroom. However, it is not the most effective intervention for preventing falls in an ambulatory and independent patient. In fact, it could potentially increase the risk of falls if the patient attempts to use the commode without assistance or if they become disoriented in the dark.

Research has shown that bedside commodes are associated with an increased risk of falls in hospitalized patients. This is because patients may try to get out of bed to use the commode without assistance, or they may become disoriented in the dark and fall.

Additionally, bedside commodes can be a tripping hazard, especially for patients with impaired mobility.

Rationale for Choice B:

Ensuring the bathroom light is kept on during the night can help to reduce the risk of falls by making it easier for the patient to see. However, it is not the most effective intervention for preventing falls.

Patients may still fall even if the bathroom light is on, especially if they are weak, unsteady, or have impaired vision. Additionally, keeping the bathroom light on all night can disrupt the patient's sleep, which can also increase the risk of falls.

Rationale for Choice C:

Using side rails to keep the patient in bed is not an effective intervention for preventing falls. In fact, it can actually increase the risk of falls by making it more difficult for the patient to get out of bed safely.

Patients may try to climb over the side rails, which can lead to falls.

Additionally, side rails can restrict the patient's movement and make them feel trapped, which can lead to agitation and an increased risk of falls.

Rationale for Choice D:

Implementing a toileting schedule is the most effective intervention for preventing falls in an ambulatory and independent patient. This is because it helps to reduce the patient's need to get out of bed at night to use the bathroom.

When a patient has a scheduled time to toilet, they are less likely to try to get out of bed on their own and risk a fall. Additionally, a toileting schedule can help to prevent incontinence, which can also lead to falls.

Rationale for Choice A:
While it's important for the primary healthcare provider to be informed about the CD4+ results, it's not the first action the nurse should take. The priority is to implement appropriate infection control measures to protect the patient, other patients, and healthcare staff.
CD4+ cell count is a crucial indicator of the patient's immune status. A count of 180/mm is significantly low, suggesting a weakened immune system and increased vulnerability to infections. However, informing the provider alone doesn't directly address the immediate need for infection control.
Rationale for Choice B:
Airborne Precautions are specifically used for patients with known or suspected airborne infections, such as tuberculosis, measles, or varicella. These precautions involve the use of negative pressure rooms and N95 respirators.
In this case, the patient's TB skin test was negative, indicating no evidence of active tuberculosis infection. Implementing Airborne Precautions unnecessarily could lead to excessive resource utilization and potential stigmatization of the patient.
Rationale for Choice C:
Droplet Precautions are used for patients with infections that can be spread through large respiratory droplets, such as influenza, pertussis, or meningococcal meningitis. These precautions involve the use of masks and eye protection.
While the patient's symptoms of fever, night sweats, and severe cough could be consistent with a droplet-spread infection, there's no definitive evidence to support this at the present time. Initiating Droplet Precautions without a clear indication could also lead to unnecessary resource use and potential anxiety for the patient.
Rationale for Choice D:
Standard Precautions are the foundation of infection control and should be used for all patients, regardless of their known or suspected infection status. These precautions include hand hygiene, use of personal protective equipment (PPE) when indicated, and safe handling of sharps and bodily fluids.

By implementing Standard Precautions, the nurse can effectively minimize the risk of transmission of pathogens, protecting both the patient and other individuals in the healthcare setting. This is the most appropriate first action to ensure a safe and appropriate level of care.
