A nurse is reviewing a client’s prescriptions and notices that the dosage of one medication is three times the usual dose.The prescribing provider is unavailable for several days. What should the nurse do next?

Choice A rationale
Increasing the client’s oral fluid intake is not the immediate action the nurse should take. While hydration is important, it does not directly address the client’s low oxygen saturation.
Choice B rationale
Initiating humidification therapy can help to thin secretions and improve oxygenation, but it is not the immediate action the nurse should take.
Choice C rationale
Raising the head of the bed is the first action the nurse should take. This position can help to improve lung expansion and oxygenation.
Choice D rationale
Encouraging the client to cough and deep breath can help to clear secretions and improve oxygenation, but it is not the immediate action the nurse should take.

Choice A rationale
Vibration is a technique used in chest physiotherapy to increase the turbulence of the client’s exhaled air. It involves the use of manual or mechanical techniques to create vibrations in the chest wall during exhalation. This helps to loosen mucus in the airways and improve clearance of secretions.
Choice B rationale
Percussion, also known as chest clapping, is a technique used in chest physiotherapy to help loosen and mobilize secretions in the lungs. However, it does not specifically increase the turbulence of exhaled air.
Choice C rationale
Postural drainage involves positioning the client in specific ways to use gravity to assist in the removal of secretions from the lungs. While it can be beneficial in managing respiratory infections, it does not directly increase the turbulence of exhaled air.
Choice D rationale

Nebulization involves the use of a machine to create a mist of medication that the client inhales into the lungs. While it can be used to deliver medications to help manage respiratory infections, it does not increase the turbulence of exhaled air.
