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 B

Explanation

A. Reviewing the blood pressure measurement is not the primary concern here; the issue is that the UAP is using the incorrect arm for the measurement.
B. The blood pressure should be measured on the non-operative side. Measuring on the operative side can cause discomfort, potential injury, or interfere with the healing process.
C. Elevating the arm after recording the blood pressure is not a standard requirement post-mastectomy. The immediate concern is the proper measurement site for the blood pressure.
D. A manual blood pressure cuff is not required for accuracy in this situation; the key issue is to use the non-operative arm for measurement.

A. Re-lubricate the tubing and re-insert it. B. Insert the tubing an additional three inches into the rectum. C. Raise the saline container six inches higher. D. Instruct the client to take several slow, deep breaths.

Correct Answer is B

Explanation

A. Re-lubricating the tubing and re-inserting it is unnecessary if the enema solution is not infusing; the primary issue is likely related to the tubing's position or the height of the container.
B. Inserting the tubing an additional three inches into the rectum ensures that it is positioned correctly for the solution to flow. If the tubing is not inserted far enough, the solution may not enter the rectum.
C. Raising the saline container higher is not needed since it is already six inches above the client’s body. The problem is more likely related to the tubing’s depth rather than the height of the container.
D. Instructing the client to take deep breaths does not affect the infusion of the enema solution. The solution's flow is influenced by the mechanics of the enema administration, not by the client’s breathing.
