A nurse is caring for a patient who has respiratory acidosis. Which of the following pH levels should the nurse expect?

pH 7.39

pH 7.31

pH 7.48

pH 7.50

Answer and Explanation

The Correct Answer is B

Choice A reason: A pH of 7.39 is near the lower end of the normal range (7.35-7.45) and would not typically indicate respiratory acidosis.

Choice B reason: A pH of 7.31 is below the normal range, indicating an acidic environment, which is consistent with respiratory acidosis.

Choice C reason: A pH of 7.48 is above the normal range, indicating a more alkaline environment, which would suggest respiratory alkalosis, not acidosis.

Choice D reason: A pH of 7.50 is also above the normal range and would indicate alkalosis rather than acidosis.

Correct Answer is B

Explanation

Choice A reason: Decreased pedal pulses could indicate a vascular issue but are not specific to DVT.

Choice B reason: Unilateral leg edema, especially when it is sudden, can be a sign of DVT and is the most indicative of the choices provided.

Choice C reason: Ecchymosis, or bruising, on the foot and ankle can be caused by many factors and is not specific to DVT.

Choice D reason: Coolness of the skin can be a sign of poor circulation but is not specific to DVT.

Correct Answer is ["5"]

Explanation

Step 1: Identify the prescribed dose and the dose per tablet. The prescribed dose is 650 mg and the dose per tablet is 125 mg.
Step 2: Divide the prescribed dose by the dose per tablet to find out how many tablets are needed. So, 650 mg (prescribed dose) ÷ 125 mg/tablet (dose per tablet) = 5.2 tablets
Since we need to round to the nearest whole number, 5.2 tablets rounds to 5 tablets.
