Rationale: Pilocarpine, a cholinergic agent, stimulates the ciliary muscle to contract, which opens the trabecular meshwork and facilitates the outflow of aqueous humor, reducing intraocular pressure. This mechanism helps in managing open-angle glaucoma by improving drainage and lowering pressure within the eye.

Monitoring the client's heart rate is essential to detect and manage this potential side effect promptly.

While this is beneficial for individuals with a history of deep vein thrombosis, it also increases the risk of bleeding. Therefore, the nurse should monitor the client for signs of bleeding, such as easy bruising, prolonged bleeding from cuts, or blood in the urine or stool. Monitoring for bleeding is crucial to ensure the client's safety and to take appropriate actions if necessary.

In this scenario, the best approach is to prescribe regular insulin subcutaneously according to a sliding scale based on the client's blood glucose levels. This method allows for precise adjustment of insulin doses to maintain blood glucose within the target range while the client is unable to take oral medications.
