Correct Answer: B

Rationale: Avoiding foods high in sodium (choice B) is essential for clients with heart failure to prevent fluid retention and decrease the strain on the heart. High sodium intake can lead to fluid buildup, exacerbating heart failure symptoms. Increasing potassium intake (choice A) can be harmful in heart failure if not monitored closely. Limiting fluid intake (choice C) may be necessary in some cases, but the specific amount should be individualized based on the client's condition. Increasing vitamin K intake (choice D) is not a primary concern in heart failure management.

Correct Answer: B

Rationale: Limiting sodium intake to 2 grams per day (B) is a crucial dietary instruction for clients with heart failure. It helps manage fluid retention and reduces the workload on the heart. Increasing fluid intake (A), avoiding potassium (C), and increasing protein intake (D) are not appropriate dietary instructions for heart failure management.

Correct Answer: C

Rationale: Cranberry juice is known for its ability to prevent urinary tract infections by reducing the adherence of Escherichia coli bacteria to the cells within the bladder. This property helps in maintaining urinary tract health and preventing recurrent UTIs.

Correct Answer: C

Rationale: The correct answer is C. For droplet precautions, such as in the case of pertussis, a standard face mask is sufficient for protection. Particulate filter masks are required for airborne precautions, not for droplet precautions. Therefore, the UAP can proceed with taking the vital signs using a standard mask without the need for a particulate filter mask. It is important for healthcare workers to understand the appropriate use of personal protective equipment based on the type of precautions in place to provide safe and effective care to clients.

Correct Answer: D

Rationale: The most crucial intervention when caring for a client with a chest tube is to ensure that the chest tube is connected to a water-seal drainage system (D). This system helps maintain proper lung expansion and prevents complications. Keeping the drainage system at chest level (A) is important to facilitate drainage, but not as critical as ensuring the connection to the drainage system. Clamping the chest tube (B) is unnecessary and can lead to serious issues. Stripping the chest tube (C) is an outdated practice and can cause harm rather than benefit.
