A patient is one day postoperative following an open thoracotomy. The patient is receiving oxygen mist at 40% by Venturi mask. The patient's ABG results are: pH 7.31, PaO2 93 mm Hg, PaCO2 50 mm Hg, HCO3 25 mEq/L. Which of the following is an appropriate action for the nurse?

Elevate the patient in a high Fowler's position and encourage the use of an incentive spirometer and coughing.

Increase oxygen to 70%.

Switch oxygen to a rebreather mask.

Position the patient prone and have the respiratory therapist perform postural drainage.

Answer and Explanation

The Correct Answer is A

Choice A reason: Elevating the patient in a high Fowler's position can help improve lung expansion and oxygenation, and using an incentive spirometer along with coughing can help prevent atelectasis and pneumonia, which are common postoperative complications.

Choice B reason: Increasing oxygen to 70% without a specific indication could lead to oxygen toxicity, especially without assessing the patient's current oxygenation status.

Choice C reason: Switching to a rebreather mask is not indicated based on the given ABG results and could lead to CO2 retention.

Choice D reason: Positioning the patient prone and performing postural drainage are not typically first-line interventions for a patient one day post-thoracotomy and could be contraindicated due to the recent surgery.

Correct Answer is B

Explanation

Choice A reason: Forming a routine at diﬀerent times of the day does not specifically address constipation and can be confusing for the patient.

Choice B reason: Increasing daily ﬂuid intake can help alleviate constipation by softening the stool and promoting bowel movements.

Choice C reason: Increasing daily activity can help with constipation, but it is not as immediate or eﬀective as increasing ﬂuid intake.

Choice D reason: Consuming a low-fiber diet is not recommended for constipation; in fact, a high-fiber diet is beneficial.

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.
