A patient with open-angle glaucoma asks the nurse how long the prescribed eye drops will need to be used. Which response made by the nurse is accurate?

Until a smaller angle can be restored.

For long-term control of normal eye pressure.

For long-term control of pain and swelling.

Until the excess pressure is reduced.

Answer and Explanation

The Correct Answer is B

A. Until a smaller angle can be restored: Open-angle glaucoma is characterized by a gradual increase in intraocular pressure due to the obstruction of the outflow of aqueous humor, not by a narrow angle. The treatment aims to control eye pressure rather than restore the angle, which is more relevant to acute angle-closure glaucoma.
B. For long-term control of normal eye pressure: Open-angle glaucoma is a chronic condition that requires ongoing management to maintain normal intraocular pressure and prevent damage to the optic nerve. The prescribed eye drops help in managing intraocular pressure over the long term to prevent vision loss.
C. For long-term control of pain and swelling: Open-angle glaucoma typically does not present with pain and swelling. The goal of treatment is to control intraocular pressure rather than address pain or swelling, which are not primary symptoms of this condition.
D. Until the excess pressure is reduced: While initial treatment aims to reduce intraocular pressure, open-angle glaucoma requires ongoing use of medications to maintain normal pressure levels and prevent progression of the disease. Discontinuing the medication after initial pressure reduction can lead to a return of elevated intraocular pressure.

Correct Answer is B

Explanation

A) Maintain a cool, calm room environment: While a calm environment can be beneficial for overall patient well-being, it is not specifically related to the care of a client on clopidogrel. This instruction does not address the direct needs or precautions associated with clopidogrel use.
B) Provide the client with a soft toothbrush: Clopidogrel is an antiplatelet medication that increases the risk of bleeding. To minimize gum bleeding and oral mucosal damage, it is crucial to use a soft toothbrush to prevent injury. This measure helps to reduce the risk of bleeding complications associated with the medication.
C) Allow the client ample rest periods: While rest is important for overall health, it is not specifically related to the precautions needed for a client on clopidogrel. The primary concern with clopidogrel is managing bleeding risks rather than providing rest.
D) Keep the head of the bed elevated: Elevating the head of the bed is generally useful for managing certain conditions like respiratory issues or gastrointestinal reflux but does not directly relate to the specific needs of a client taking clopidogrel. The focus for clients on clopidogrel should be on preventing bleeding complications.

A. Pull up 30 units from the 70/30 vial, but only administer one third. B. Withdraw ten units regular insulin from the 70/30 vial. C. Withhold the dose until insulin regular is available on the unit. D. Obtain a new vial of regular insulin and withdraw ten units.

Correct Answer is C

Explanation

A) Pull up 30 units from the 70/30 vial, but only administer one third: The 70/30 insulin vial contains a mixture of 70% isophane (NPH) insulin and 30% regular insulin. If 30 units of this mixture are drawn, the actual amount of regular insulin would be 30% of 30 units, which equals 9 units. This does not equate to the 10 units of regular insulin required, making this option inaccurate for precise dosing.
B) Withdraw ten units regular insulin from the 70/30 vial: The 70/30 vial provides a fixed ratio of regular to NPH insulin. Extracting 10 units from this vial would not yield exactly 10 units of regular insulin; instead, it would include both types in the specified ratio, leading to an incorrect dosage of regular insulin.
C) Withhold the dose until insulin regular is available on the unit: Since the 70/30 vial contains a mixture and not solely regular insulin, it is necessary to withhold the dose until a vial of regular insulin is available. This ensures that the precise amount of regular insulin needed is administered, avoiding the imprecision and potential errors that could arise from using a mixed insulin vial.
D) Obtain a new vial of regular insulin and withdraw ten units: While obtaining a new vial of regular insulin is the correct approach for ensuring accurate dosing, the option of withdrawing ten units directly from a vial of regular insulin is not feasible if the current medication available is a mixture. This option assumes that the correct type of insulin is already available for use.
