Which assessment finding indicates to the practical nurse that a Venturi face mask is producing the desired effect?

Increased oxygen saturation.

Increased cough productivity.

Decreased cough frequency.

Decreased breath sounds.

Answer and Explanation

The Correct Answer is A

A. Increased oxygen saturation indicates that the Venturi face mask is effectively delivering the specified concentration of oxygen. This is the primary goal of using a Venturi mask, which provides precise oxygen delivery to improve oxygen saturation levels.
B. Increased cough productivity is not a direct indicator of the effectiveness of a Venturi face mask. The mask's purpose is to deliver oxygen, not to alter cough patterns.
C. Decreased cough frequency is unrelated to the function of the Venturi face mask. The mask's effectiveness is measured by oxygen delivery rather than changes in cough frequency.
D. Decreased breath sounds are not a direct measure of the effectiveness of a Venturi face mask. Breath sounds could indicate other respiratory issues but do not specifically reflect the effectiveness of oxygen therapy.

Correct Answer is D

Explanation

A. Keeping the head of the bed elevated is not specifically related to the care of a PICC line. The elevation may be a general comfort measure but is not a specific instruction for PICC line management.
B. Changing the dressing over the PICC line insertion site is a sterile procedure that should be performed by a licensed nurse, not a UAP. This task requires specific training and adherence to infection control practices.
C. Feeding the client all meals to reduce arm movement is not necessary and may be overly restrictive. The UAP’s role does not include limiting the client's activity beyond reasonable measures.
D. Using the opposite arm for blood pressure measurement is the correct guidance. It prevents potential interference with the PICC line and helps avoid complications such as dislodgement or infection.
