The nurse emphasizes the importance of deep breathing and coughing exercises post-operatively to prevent complications. Which statement by the client indicates understanding of these exercises?

"I will perform deep breathing exercises only when the pain is minimal."

"I will perform deep breathing exercises every hour while awake."

“I will perform coughing exercises only if I feel short of breath."

"I will avoid deep breathing exercises to prevent straining my incision."

Answer and Explanation

The Correct Answer is B

A.   Deep breathing exercises should be performed regularly, regardless of the level of pain. The exercises are crucial for preventing lung complications, and pain management should be addressed so that the client can perform these exercises effectively.
B.   This statement reflects a proper understanding of the importance of regular deep breathing exercises. Performing these exercises every hour while awake helps to keep the alveoli open and reduces the risk of atelectasis and pneumonia. Consistent practice is essential for maximizing lung expansion and preventing complications.
C.   Coughing exercises should be performed regularly, not just when experiencing shortness of breath. Coughing helps to clear secretions from the airways and prevent their accumulation, which can lead to respiratory infections and other complications.
D.   Avoiding deep breathing exercises is not advisable. While there may be some discomfort, deep breathing is essential for lung health post-operatively. The exercises help prevent complications such as atelectasis.

Correct Answer is C

Explanation

A. pH 7.35, PaCO2 40 mm Hg, HCO3-25 mEq/L: This is within normal ranges and does not indicate acidosis.
B. pH 7.32, PaCO2 47 mm Hg. HCO3-23 mEq/L: This indicates respiratory acidosis, not metabolic.
C. pH 7.3, PaCO2 36 mm Hg. HCO3- 19 mEq/L: This indicates metabolic acidosis. The pH is low (acidic), and the HCO3- (bicarbonate) is decreased. The PaCO2 is within normal limits, indicating the respiratory system is compensating for the metabolic acidosis.
D. pH 7.5, PaCO2 35 mm Hg, HCO3- 35 mEq/L: This indicates alkalosis, not acidosis.

Correct Answer is ["100"]

Explanation

To calculate the rate at which the IV pump should be set to deliver the medication, you would use the formula:

(Total Volume in mL / Time in hours) = mL/hr.

The total volume of the IV bag is 50 mL and the time frame is 0.5 hours (since 30 minutes is half an hour). So, the calculation would be 50 mL / 0.5 hours = 100 mL/hr.

Therefore, the nurse should set the IV pump to deliver 100 mL/hr to administer 500 mg of ampicillin over 30 minutes.
