A nurse is reinforcing teaching with a client about self-administration of ophthalmic drops. Which of the following instructions should the nurse include?

The correct answer is choice A. Perform a bladder scan.

Choice A rationale:

Performing a bladder scan is the first action the nurse should take before proceeding with intermittent urinary catheterization. A bladder scan assesses the bladder's volume and determines if catheterization is necessary. It helps avoid unnecessary catheterizations, reduces the risk of infection, and promotes patient comfort.

Choice B rationale:

While cleansing the meatus and providing perineal care are important steps in preparing for urinary catheterization, they come after assessing the need for catheterization. Without knowing the bladder volume, these actions could be premature.

Choice C rationale:

Providing perineal care is important for maintaining hygiene and preventing infection, but it should be done after the decision for catheterization has been made based on the bladder scan results.

Choice D rationale:

Lubricating the catheter is a step that should be taken after the decision for catheterization is made and the need for catheterization is confirmed. It helps ease the insertion process and reduce discomfort for the patient.

The correct answer is **d. Attach a humidifier to the base of the flow meter**.

Choice A rationale:

Keeping the side holes of the mask closed would restrict airflow and prevent the client from receiving the prescribed oxygen concentration. This action would be unsafe and should not be taken.

Choice B rationale:

Ensuring the reservoir bag is inflated on expiration is not necessary for a simple face mask. The reservoir bag is typically used with other oxygen delivery devices, such as a non-rebreather mask, to provide a higher concentration of oxygen. This action is not appropriate for the given scenario.

Choice C rationale:

Applying petroleum jelly to the client's nostrils is not a recommended action. Petroleum jelly can potentially cause irritation and dryness, which could lead to discomfort for the client. This action is not necessary for the safe administration of oxygen.

Choice D rationale:

Attaching a humidifier to the base of the flow meter is the appropriate action to ensure client safety. Humidifying the oxygen can help prevent drying of the client's airway and make the oxygen more comfortable to breathe. This is a recommended step when administering high-flow oxygen via a simple face mask.
