A nurse suspects impending respiratory failure in a client diagnosed with chronic obstructive pulmonary disease (COPD). The nurse should recognize that which assessment finding supports the presence of hypoxemia?
The client has circumoral cyanosis.
The client's heart rate is 86 bpm.
The client has a pulse ox of 90% on room air.
The client is lethargic.
The Correct Answer is C
A. The client has circumoral cyanosis: Circumoral cyanosis, or bluish discoloration around the mouth, is a sign of hypoxia but may not be present in all cases of hypoxemia. Pulse oximetry provides a more objective measurement.
B. The client's heart rate is 86 bpm: Heart rate may be within normal limits even in the presence of hypoxemia, as compensatory mechanisms may not be fully activated.
C. The client has a pulse ox of 90% on room air: A pulse oximetry reading of 90% indicates hypoxemia (oxygen saturation below normal levels), which is a significant finding, especially in a client with COPD who may already have compromised respiratory function.
D. The client is lethargic: Lethargy may occur with severe hypoxemia, but it is a late sign and may not always be present. Monitoring oxygen saturation is more reliable for early detection of hypoxemia.

Correct Answer is B
Explanation
A. Morphine sulfate 2 mg IV bolus every 2 hr PRN pain: This prescription is appropriate for managing pain associated with acute heart failure and MI.
B. Bumetanide 1 mg IV bolus every 12 hr: Bumetanide is a loop diuretic commonly used in heart failure to reduce fluid overload. However, the frequency of administration (every 12 hours) may not be sufficient for managing acute heart failure, where more frequent dosing may be necessary initially.
C. Laboratory testing of serum potassium upon admission: This is a routine and appropriate order to monitor electrolyte balance, especially with the use of diuretics.
D. 0.9% normal saline IV at 75 mL/hr: This is a maintenance IV fluid rate that may be appropriate depending on the client's fluid status. However, it does not directly address acute heart failure.
Correct Answer is D
Explanation
A. Grilled chicken, white rice, sliced peaches: While grilled chicken is a lean protein source, white rice is low in fiber and may not be the best choice for someone experiencing severe diarrhea. Sliced peaches are a good fruit choice, but the meal lacks sufficient fiber and other nutrients.
B. Spaghetti with tomato sauce, meatballs, and garlic bread: This meal contains high-fat and high-carbohydrate foods, which may exacerbate diarrhea. Tomato sauce can be acidic and irritating to the digestive system for some individuals.
C. Fried shrimp, cauliflower, yogurt with granola: Fried foods are high in fat and may worsen diarrhea. Cauliflower is a good vegetable choice, but yogurt with granola may not be well- tolerated if the client is lactose intolerant or sensitive to dairy products.
D. Grilled salmon, brown rice, broccoli: Grilled salmon provides lean protein and omega-3 fatty acids, which can be beneficial for overall health. Brown rice is higher in fiber compared to white rice and can help regulate bowel movements. Broccoli is a good source of fiber and essential nutrients. This meal is well-balanced and nutritious, making it a suitable choice for someone experiencing diarrhea.
