The nurse is scheduled to administer the patient’s next dose of vancomycin at 9:30 a.m. At what time should the nurse draw the patient’s blood to check the trough vancomycin level?

Choice A rationale:

Incorrect because swallowing the tablet with water would lead to slower absorption and a delayed onset of action. Nitroglycerin is rapidly absorbed through the oral mucosa, and swallowing it would route it through the digestive system, where it would be absorbed more slowly and less effectively.

Swallowing the tablet could also increase the risk of side effects, such as headache and flushing, due to the larger amount of the drug that would be absorbed systemically.

Choice B rationale:

Incorrect because crushing the tablet and dissolving it in water would also delay its absorption. This method would require the tablet to dissolve in the water before it could be absorbed through the oral mucosa, which would slow down the onset of action.

Crushing the tablet could also damage the medication and make it less effective.

Choice C rationale:

Incorrect because placing the tablet in the patient's mouth next to the cheek would not allow for optimal absorption. The oral mucosa under the tongue is more permeable than the cheek, so placing the tablet under the tongue allows for faster and more efficient absorption.

Placing the tablet in the cheek could also increase the risk of the patient accidentally swallowing it.

Choice D rationale:

Correct because placing the tablet under the patient's tongue allows for rapid absorption and a quick onset of action. The sublingual route is the preferred method of administration for nitroglycerin because it allows the medication to bypass the digestive system and be absorbed directly into the bloodstream.

This method also allows for the patient to easily remove the tablet if they experience any side effects.

Choice A rationale:

Splinting the incision when coughing helps to minimize pain and discomfort, which can encourage deeper breathing and coughing. This is essential because deep breathing and coughing help to clear secretions from the lungs and prevent atelectasis (collapse of lung tissue).

Steps for splinting the incision:

Place a pillow or folded towel over the incision site.

Instruct the patient to apply gentle pressure to the pillow or towel with their hands when coughing or deep breathing. Encourage the patient to relax their abdominal muscles during coughing and deep breathing exercises.

Choice B rationale:

Sitting up in a chair and ambulating promote lung expansion and help to mobilize secretions. This is because gravity assists in moving secretions from the smaller airways into the larger airways, where they can be more easily coughed up.

Additional benefits of sitting up and ambulating: Improved circulation

Decreased risk of pneumonia Enhanced recovery from surgery Choice C rationale:

Using an incentive spirometer hourly helps to increase lung capacity and prevent atelectasis. The device encourages the patient to take slow, deep breaths, which helps to inflate the alveoli (air sacs) in the lungs.

Instructions for using an incentive spirometer:

Sit upright in a chair or bed.

Place the mouthpiece of the spirometer in your mouth and seal your lips around it.

Inhale slowly and deeply through the mouthpiece, aiming to raise the piston inside the device as high as possible. Hold your breath for 3-5 seconds.

Exhale slowly and completely through the mouthpiece.

Repeat the process 10-15 times per hour, or as instructed by your healthcare provider.
