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%.

Home health evaluation of home safety: Expected, as it can help prevent falls, which are a significant risk for patients with osteoporosis due to increased fracture risk.
Vitamin D supplement 2,500 units daily: Expected, since Vitamin D is essential for calcium absorption and bone health, and supplementation is commonly recommended for osteoporosis patients.
Calcium 1500 mg po once daily on an empty stomach: Expected, because adequate calcium intake is crucial for maintaining bone density and overall bone health.
Increase caffeine intake: Unexpected, as excessive caffeine can interfere with calcium absorption and exacerbate bone density loss.
Physical therapy for muscle-strengthening and balance-training: Expected, to improve muscle strength, balance, and coordination, which can help reduce the risk of falls and subsequent fractures.
Increase daily sun exposure: Expected, but with caution. While sun exposure helps with Vitamin D synthesis, it should be balanced with skin cancer risk, especially in older adults.

A. "I will empty my drainage bag once a day." B. "I will apply antiseptic ointment to the tip of my penis." C. "I will keep the drainage bag below the level of my waist." D. "I will clamp the tube when I go for a walk."

Correct Answer is C

Explanation

Emptying the drainage bag once a day is not frequent enough and could lead to overfilling and potential urinary tract infections.

Applying antiseptic ointment to the tip of the penis is not recommended as it can cause irritation and increase the risk of infection.

Keeping the drainage bag below the level of the waist helps prevent backflow of urine into the bladder and reduces the risk of infection.

Clamping the tube when going for a walk can cause urine to back up into the bladder and increase the risk of infection.
