Answer and Explanation

Correct Answer : A,C,D,E

Choice A reason: Performing deep breathing exercises every 2 hours helps prevent postoperative complications such as pneumonia and atelectasis.

Choice B reason: While chest movement is part of breathing, the instruction is incomplete and should emphasize diaphragmatic breathing rather than shoulder movement.

Choice C reason: Taking a deep breath before coughing helps to increase the eﬀectiveness of the cough, which can clear secretions from the lungs.

Choice D reason: Sitting up straight before beginning coughing exercises helps to ensure maximum lung expansion and eﬀectiveness of the cough.

Choice E reason: Using a pillow to support the surgical area when coughing can help reduce pain and protect the incision site, making the cough more eﬀective.

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.

A. Metabolic acidosis B. Respiratory acidosis C. Metabolic alkalosis D. Respiratory alkalosis

Correct Answer is A

Explanation

Choice A reason: Metabolic acidosis is characterized by a low pH and a normal or low HCO3. In this case, the pH is 7.25, which is below the normal range of 7.35-7.45, and the HCO3 is 22, which is at the lower end of the normal range of 22-26 mEq/L, indicating metabolic acidosis.

Choice B reason: Respiratory acidosis is characterized by a high CO2 level. However, in this scenario, the CO2 is 40, which is within the normal range of 35-45 mmHg, ruling out respiratory acidosis.

Choice C reason: Metabolic alkalosis would present with a high pH and a high HCO3 level. Since the pH is low, metabolic alkalosis is not the correct answer.

Choice D reason: Respiratory alkalosis is characterized by a low CO2 level and a high pH. Given that the CO2 is normal and the pH is low, respiratory alkalosis is not the condition indicated by these ABG results.
