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 A

Explanation

A. Maternal hypotension is a significant adverse effect of epidural anesthesia that can lead to decreased uterine blood flow and fetal distress. Monitoring for hypotension is critical to ensure both maternal and fetal well-being.
B. While a vaginal hematoma is a potential complication, it is less immediately associated with the administration of epidural anesthesia compared to hypotension.
C. A continuous headache could indicate post-dural puncture but is less common and not the primary immediate concern compared to hypotension following an epidural.
D. Urinary retention can occur with epidural anesthesia, but maternal hypotension is a more urgent and significant immediate concern.

A. Suggest a less strenuous activity to reduce the risk for dehydration. B. Reassure the parents that increased physical activity reduces the risk for diabetes. C. Recommend an increase in caloric intake to avoid excessive weight loss. D. Instruct the family about the need to adjust the insulin dose before exercise.

Correct Answer is B

Explanation

A. Suggesting a less strenuous activity is not necessary as physical activity is beneficial in managing pre-diabetes.
B. Reassuring the parents that increased physical activity reduces the risk for diabetes encourages healthy habits and supports the child’s desire to participate in sports.
C. Increasing caloric intake should be balanced and appropriate for the child's needs but isn't the primary focus in this context.
D. Adjusting insulin doses is important for children with diabetes, but the focus here is on encouraging physical activity to manage pre-diabetes, not insulin adjustments.
