Which oxygen delivery device can deliver 40-60% FIO2 and is from 5-8 L/min?

Nasal cannula

Simple face mask

Aerosol mask

Face tent

Answer and Explanation

The Correct Answer is B

A: A nasal cannula delivers a lower concentration of oxygen, typically between 24-44% FIO2, and is used at flow rates of 1-6 L/min. It is not suitable for delivering 40-60% FIO2.

B: A simple face mask can deliver 40-60% FIO2 at flow rates of 5-8 L/min. It covers the nose and mouth, providing a higher concentration of oxygen compared to a nasal cannula.

C: An aerosol mask is used for delivering humidified oxygen or medications via nebulization. It can deliver varying concentrations of oxygen but is not specifically designed for 40-60% FIO2 at 5-8 L/min.

D: A face tent is used for patients who cannot tolerate a mask, such as those with facial trauma or claustrophobia. It provides humidified oxygen but does not deliver a precise FIO2 concentration.

Correct Answer is D

Explanation

A: Placing the client supine with knees bent can help reduce strain on the abdominal area but is not the immediate first action.

B: Raising the head of the client’s bed 15 to 20 degrees is not the priority action in this situation.

C: Assessing the client for manifestations of shock is important but should follow the immediate action of protecting the eviscerated wound.

D: Covering the area with a sterile dressing moistened with 0.9% sodium chloride irrigation is the correct first action. This helps protect the exposed organs and tissues from contamination and keeps them moist until surgical intervention can be performed.

A. Passage of flatus B. Request for a cup of tea and some toast C. Hypoactive bowel sounds in two quadrants D. Abdominal distention

Correct Answer is A

Explanation

A: The passage of flatus is a clear indication that intestinal function is returning. It shows that the gastrointestinal tract is beginning to move gas through the intestines, which is a positive sign of recovery after abdominal surgery.

B: A request for a cup of tea and some toast indicates that the client is feeling better and has an appetite, but it does not specifically indicate the return of intestinal function.

C: Hypoactive bowel sounds in two quadrants suggest reduced intestinal activity, which is not a sign of returning intestinal function. Normal bowel sounds should be present in all quadrants.

D: Abdominal distention can indicate a buildup of gas or fluid in the intestines, which is not a sign of returning intestinal function. It may suggest an obstruction or other complications.
