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. NSAIDs are not associated with the characteristic features of truncal obesity, moon face, and buffalo hump.
B. Corticosteroids can cause truncal obesity, moon face, and buffalo hump as side effects due to their effects on metabolism and fat distribution.
C. Thyroid replacement hormone is used to treat hypothyroidism and does not cause the symptoms described.
D. Insulin is used to manage diabetes and does not typically cause the features seen in Cushing’s syndrome associated with corticosteroid use.

A. Acceleration. B. Nonreactive pattern. C. Fetal movement. D. Positive tracing.

Correct Answer is A

Explanation

A. Acceleration refers to a temporary increase in the fetal heart rate of at least 15 beats per minute above the baseline for at least 10 seconds. The observation of the fetal heart rate increasing 15 beats above baseline twice during the test indicates that accelerations are present, which is a reassuring sign of fetal well-being.
B. A nonreactive pattern would indicate that the test did not meet the criteria for accelerations or fetal heart rate reactivity, which is not the case here as the fetal heart rate did exhibit accelerations.
C. Fetal movement could contribute to accelerations but is not the term used to describe the findings of the test itself. The specific observation made was an increase in fetal heart rate, which is classified as an acceleration.
D. A positive tracing indicates that the nonstress test met criteria for fetal well-being, typically with at least two accelerations, but the correct term for the specific observation here is acceleration rather than describing the overall result.
