A nurse is preparing to administer diphenhydramine 25 mg PO every 6 hr. to an older adult client who has rhinitis. The amount available is diphenhydramine syrup 12.5 mg/5 mile How many ml should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A Reason:
Replace the unit when the drainage chamber is full is correct. Regularly emptying the drainage chamber when it becomes full is essential to ensure the drainage system functions properly and continues to effectively remove fluids or air from the chest cavity.

Choice B Reason:
Clamp the tube for 30 min every 8 hr. is incorrect.
Clamping a chest tube without a specific medical order or indication can lead to complications such as a buildup of pressure within the chest cavity or potential damage to the lungs. It's generally not a routine action to clamp the tube without proper instruction.

Choice C Reason:
Pin the tubing to the client's bed sheets is incorrect. Pinning the tubing to the bed sheets can cause tension on the chest tube, leading to accidental dislodgment or obstruction. The tubing should be secured but not pinned to prevent inadvertent movement.

Choice D Reason:
Monitor for at least 150 mL of drainage every hour is incorrect. There isn't a standard or prescribed amount of drainage that should occur hourly. The nurse should monitor the drainage rate and characteristics but shouldn't expect a specific volume within a set timeframe. Monitoring for excessive or decreased drainage and changes in characteristics is crucial, but an hourly volume expectation isn't appropriate.

Choice A Reason:

Administering a prescribed oral dose of trazodone to the client is correct. Trazodone is sometimes used to manage agitation in patients with Alzheimer's disease, as it has calming effects and can help reduce agitation and anxiety. However, the use of any medication should be based on the client's individualized treatment plan and prescribed by a healthcare provider.

Choice B Reason:

Encouraging ambulation might not be suitable if the client is agitated, as it could potentially escalate the situation or increase the risk of falls or injury. Safety should be a priority, and ambulation might not be advisable during a state of agitation.

Choice C Reason:

Isolating the client in their room is incorrect. Isolating the client might increase feelings of confusion, fear, or distress, potentially worsening the agitation. It's important to engage and support the client rather than isolate them, which can be distressing for someone with Alzheimer's disease.

Choice D Reason:

Applying bilateral wrist restraints to the client is incorrect. The use of restraints should only be considered as a last resort when all other measures have failed and when there's an immediate risk of harm to the client or others. Restraints can be physically and psychologically harmful, leading to increased agitation, anxiety, and potential injury. They should be used only under strict guidelines and with proper authorization when all other interventions have been exhausted.
