A nurse receives an order from the provider for a client requiring the highest oxygen concentration with a one-way valve. What type of mask should the nurse apply to the client?

Simple face mask

Venturi mask

Non-rebreather mask

Partial rebreather mask

Answer and Explanation

The Correct Answer is C

A: A simple face mask provides a moderate concentration of oxygen but does not have a one-way valve to deliver the highest concentration of oxygen.

B: A Venturi mask delivers a precise concentration of oxygen but is not designed to provide the highest concentration of oxygen with a one-way valve.

C: A non-rebreather mask is the correct choice. It has a one-way valve that prevents exhaled air from re-entering the bag, allowing the delivery of the highest concentration of oxygen to the client.

D: A partial rebreather mask provides a high concentration of oxygen but does not have a one-way valve, making it less effective than a non-rebreather mask for delivering the highest oxygen concentration.

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.

A. Hypoglycemia B. Hypertension C. Hypervolemia D. Hypokalemia

Correct Answer is D

Explanation

A: Hypoglycemia is not a common adverse effect of Furosemide. This diuretic primarily affects fluid and electrolyte balance rather than blood glucose levels.

B: Hypertension is not an adverse effect of Furosemide. In fact, Furosemide is often used to treat hypertension by reducing fluid volume and lowering blood pressure.

C: Hypervolemia, or fluid overload, is not an adverse effect of Furosemide. This medication is a diuretic, which means it helps remove excess fluid from the body, thereby reducing hypervolemia.

D: Hypokalemia, or low potassium levels, is a common adverse effect of Furosemide. This diuretic can cause the body to lose potassium through urine, leading to potentially dangerous low levels of this essential electrolyte.
