The nurse's assistant is having difficulty carrying out a delegated task. The first step the nurse should take is to:

C. Rapid heart rate (tachycardia) can be a sign of fluid overload, as the heart compensates for increased volume by beating faster to maintain cardiac output.

D. Shortness of breath (dyspnea) can indicate fluid overload, especially if it is new or worsening and associated with pulmonary congestion due to fluid accumulation.

E Elevated blood pressure can be a sign of fluid overload, as increased circulating volume can lead to hypertension.

A. This statement suggests a decrease in peripheral edema, which is a positive sign and does not typically indicate fluid overload. It may actually indicate improvement.

B. Dizziness can be a symptom of hypovolemia (low fluid volume) rather than fluid overload. It is not typically a specific sign of fluid overload.

A. Giving a written warning is a serious disciplinary action that should only be considered after other steps to support and assist the assistant have been taken. It does not promote a supportive or constructive approach to resolving the issue.

B. This option involves the nurse providing guidance and support to the assistant. By acting as a role model, the nurse can demonstrate the correct way to approach the task and provide alternative solutions or techniques. This approach encourages learning and professional development for the assistant.

C. While this may temporarily resolve the issue, it does not address the assistant's competency or provide an opportunity for learning and growth. It may also undermine the assistant's confidence and independence in performing the task.

D. While providing another task might offer another chance for success, it does not directly address the current difficulty with the delegated task. The nurse should focus on addressing the specific challenge at hand before assigning additional tasks.
