A nurse is about to administer a daily dose of potassium chloride 20 mEq suspension orally.

The available amount is potassium chloride suspension 10 mEq/mL.

How many mL should the nurse administer?

Choice A rationale

Insulin glargine does not last for 3 to 6 hours. It is a long-acting insulin that has a duration of action up to 24 hours.

Choice B rationale

This is correct. Insulin glargine lasts for 18 to 24 hours. It is a long-acting insulin that provides a base level of insulin that keeps working for 24 hours or longer.

Choice C rationale

This is also correct. Insulin glargine lasts for 16 to 24 hours. It is a long-acting insulin that provides a base level of insulin that keeps working for 24 hours or longer.

Choice D rationale

Insulin glargine does not last for 6 to 10 hours. It is a long-acting insulin that has a duration of action up to 24 hours.

Choice A rationale

Lubricating the suction catheter tip with sterile saline is not recommended because it can introduce bacteria into the tracheostomy tube and cause infection.

Choice B rationale

Hyperventilating the patient on 100% oxygen prior to suctioning is not necessary and can cause complications such as oxygen toxicity.

Choice C rationale

Performing chest physiotherapy prior to suctioning is not typically done during tracheostomy care. Chest physiotherapy is a separate procedure that involves physical techniques to remove mucus from the respiratory tract.

Choice D rationale

Suctioning two to three times with a 60-second pause between passes is the correct action. This helps to remove secretions effectively without causing hypoxia.
