A nurse is caring for a client who has dyspnea with an oxygen saturation of 88%. Which of the following indicates the type of face mask the nurse should use to deliver the client a 90% oxygen concentration?

Simple face mask

Nasal prongs

Non-rebreather mask

Nasal cannula

Answer and Explanation

The Correct Answer is C

A. Simple face mask: This can deliver oxygen at flow rates of 5-10 liters per minute and typically provides an oxygen concentration of about 35-50%.

B. Nasal prongs: Nasal prongs deliver oxygen at lower flow rates and may not be sufficient to raise the client's oxygen saturation to 90%.

C. Non-rebreather mask: This mask can deliver high concentrations of oxygen (up to 90-100%) at flow rates of 10-15 liters per minute. It has one-way valves to prevent the patient from rebreathing exhaled air, thus maximizing the delivery of oxygen.

D. Nasal cannula: Nasal cannulas deliver oxygen at lower flow rates (typically up to 6 liters per minute) and may not provide the necessary concentration to achieve an oxygen saturation of 90%.

Correct Answer is D

Explanation

A. Inflating the catheter's balloon is not appropriate when resistance is encountered before reaching the bladder. It could cause trauma or injury.
B. Lowering the penis to a 45° angle may help facilitate catheter insertion initially, but if resistance is encountered, further interventions are needed.
C. Applying lidocaine gel to the urethra may help with discomfort during catheter insertion but will not address the issue of encountering resistance.
D. Twisting the catheter gently can help navigate any obstructions or curves in the urethra. This maneuver should be performed carefully to avoid causing trauma to the urethral mucosa.

A. "I love to eat apples and black-eyed peas." B. "I drink an average of 2,000 milliliters of water daily." C. "I take a prescribed opioid pain medication at bedtime." D. "I drink two hot cups of coffee each morning."
