The nurse is caring for a client who has signs and symptoms of heart failure. Which of the following diagnostic tests is appropriate to assess the patient’s heart failure?

A. Partial non-rebreathing mask:

This mask delivers higher concentrations of oxygen than a nasal cannula. It has a reservoir bag that allows the client to rebreathe some exhaled air, increasing the oxygen concentration delivered. However, it may not be necessary for a client with mild shortness of breath and slightly reduced oxygen saturation.

B. Simple (Oxy Plus) mask:

The simple mask provides a higher concentration of oxygen than a nasal cannula but lacks the reservoir bag found in the non-rebreathing mask. It is generally used for moderate oxygen needs. However, it might be more than what is required for a client with mild shortness of breath and slightly reduced oxygen saturation.

C. Nasal cannula:

Nasal cannulas are commonly used for clients with mild respiratory distress. They deliver a lower to moderate concentration of oxygen and are well-tolerated by most clients. They are suitable for individuals with mild shortness of breath and can be adjusted based on the required flow rate.

D. Non-rebreathing mask:

The non-rebreathing mask provides the highest concentration of oxygen among the options listed. It includes a reservoir bag to deliver a higher oxygen concentration. It is typically reserved for clients with higher oxygen requirements. For a client with mild shortness of breath and slightly reduced oxygen saturation, this may be more than necessary.

Withhold food and oral fluids before the procedure

Withholding food and oral fluids before the procedure is essential to prevent complications during the cardiac catheterization. The client is typically NPO (nothing by mouth) for a specified period before the procedure.

B. Review medications the client has taken in the last 24 hours

Reviewing the client's medications is crucial to ensure that any medications affecting coagulation or blood vessels are appropriately managed before the cardiac catheterization.

C. Verify that written consent has been obtained

Verifying the presence of written consent is a critical step to confirm that the client has been adequately informed about the procedure, its risks, and benefits, and has given consent for the cardiac catheterization.

D. Check for iodine sensitivity

Checking for iodine sensitivity is important because iodinated contrast dye is commonly used during cardiac catheterization. Allergies or sensitivities to iodine contrast must be identified to prevent adverse reactions.

E. Administer all ordered oral medications

Administration of oral medications before the procedure depends on the specific medications and the healthcare provider's instructions. Some medications may be held, while others may be continued as prescribed.
