A nurse is performing chest physiotherapy on a client with a respiratory infection.
Which technique should the nurse use to increase the velocity and turbulence of the client’s exhaled air?
Vibration
Percussion
Postural drainage
Nebulization
The Correct Answer is A
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.

Correct Answer is ["A","C","E"]
Explanation
Choice A rationale
Checking that the client’s restraints are secured with a half-bow knot is a good practice. This type of knot is secure but can be easily untied, which is important for quick removal of the restraints if necessary.
Choice B rationale
Requesting that the provider prescribe the restraints as PRN is not a good practice. Restraints should only be used as a last resort and must be ordered by a healthcare provider. The order must specify the reason for the restraints and the duration of use.
Choice C rationale
Ensuring that the client’s wrists are padded is a good practice. Padding helps to prevent skin breakdown and nerve damage.
Choice D rationale
Loosening the restraints once every 4 hours is not a good practice. Restraints should be removed or loosened every 2 hours to allow for skin care and assessment, range of motion exercises, and to check for signs of injury.
Choice E rationale
Documenting client care every 15 minutes is a good practice. This includes documenting the client’s behavior, the type and location of restraints, the frequency of care (at least every 2 hours), and the client’s response to the restraints.
Correct Answer is ["2 ."]
Explanation
Step 1: Identify the prescribed dose and the available dose. The prescribed dose is 500 mg and the available dose is 250 mg per tablet.
Step 2: Use the formula for calculating the number of tablets: (Prescribed dose ÷ Available dose) = Number of tablets.
Step 3: Substitute the values into the formula: (500 mg ÷ 250 mg/tablet) = 2 tablets. So, the nurse should administer 2 tablets.
