The nurse is caring for a client three hours after percutaneous coronary intervention (PCI) with stent placement. The client now complains of 5/10 chest pain. The client is visibly diaphoretic and anxious. The ECG shows ST segment elevations. The vital signs are as follows: BP: 156/82, HR: 110, RR: 20, T: 98.6, and Sp02: 94% on 2L nasal canula. The nurse anticipates which intervention in this situation?

A. Hand washing before and after client contact: The most important infection control guideline when caring for a client with acute respiratory distress syndrome (ARDS) who is on a ventilator is hand hygiene. This is because ventilated patients are at high risk for ventilator-associated pneumonia (VAP) and other infections. Hand washing is the most effective method of preventing the spread of pathogens that could lead to nosocomial infections. The nurse should perform proper hand hygiene both before and after any patient interaction, as this is critical in preventing the transmission of bacteria or viruses, especially in patients with compromised respiratory systems.

Explanation of each option:

B. Placement of an indwelling urinary catheter using sterile technique:
While using sterile technique when placing an indwelling urinary catheter is essential to prevent urinary tract infections (UTIs), it is not the top priority for infection control in this situation. The primary concern for infection in ARDS patients who are on mechanical ventilation is preventing respiratory infections, particularly ventilator-associated pneumonia (VAP). Although catheter-associated infections should be prevented, the most immediate concern is preventing respiratory-related infections.

C. Initiate neutropenic precautions:
Neutropenic precautions are important for patients who have immunocompromised conditions (such as those undergoing chemotherapy or with bone marrow suppression) to protect them from infections. However, ARDS does not necessarily compromise the immune system in the same way. The priority infection control measure for a patient on a ventilator with ARDS is preventing respiratory infections. Therefore, neutropenic precautions would not be the most relevant or highest priority in this case.

D. Clean technique with central IV line care:
Maintaining clean technique with central intravenous (IV) line care is important to prevent infections, such as central line-associated bloodstream infections (CLABSI). However, the most critical infection control measure for a patient on a ventilator with ARDS is still to focus on preventing respiratory infections, particularly ventilator-associated pneumonia (VAP). While IV line care is important, it is secondary to preventing respiratory tract infections in this scenario.

A) Arrange for social service consult for assistance with medication purchase:
While arranging for social service support can be beneficial in ensuring the client has access to necessary medications, this is not directly related to fall prevention at home. Falls in Parkinson's disease are more closely associated with mobility, balance, and environmental factors, which should be the focus of interventions aimed at reducing fall risk. Medication access is important but secondary to safety measures related to physical environment and mobility.

B) Have the client seen by a nursing assistant 3 times a week for hygiene:
While assistance with hygiene can certainly help support the client’s daily needs, the frequency of visits for hygiene care alone does not specifically address fall prevention. Falls are more directly linked to issues such as impaired balance, freezing episodes, and poor mobility—issues that should be addressed through environmental modifications and specific interventions aimed at improving safety during ambulation and transfers.

C) Ensure adequate lighting in areas where the client will ambulate:
Ensuring adequate lighting in areas where the client will ambulate is a critical intervention for fall prevention in individuals with Parkinson's disease. Parkinson's disease often causes balance and coordination problems, and inadequate lighting can increase the risk of tripping or falling, especially at night or in poorly lit areas. Proper lighting helps the client see obstacles and navigate their environment safely. This intervention directly addresses a key factor in fall risk and is an important part of the plan of care.

D) Refer the client to a nutritionist to address dietary measures:
Referral to a nutritionist can be helpful in managing some aspects of Parkinson's disease, particularly for addressing issues like constipation, weight management, or dysphagia. However, dietary measures do not have a direct impact on fall prevention. Fall prevention should focus more on mobility, strength, environmental safety, and managing the symptoms of Parkinson's disease that affect balance and movement.
