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.

Correct Answer: B

Rationale: In insulin administration, regular insulin is typically administered before isophane insulin to manage blood glucose effectively. Therefore, if regular insulin is not available, it is best to withhold the dose until it can be administered as prescribed.

Correct Answer: A

Rationale: Exenatide, a medication commonly used in type 2 diabetes, is known to cause gastrointestinal side effects, such as nausea. Monitoring for nausea is essential as it can lead to decreased appetite and potential weight loss, affecting the nutritional status of the client. While hypoglycemia and hyperglycemia are important to monitor in diabetes management, they are not typically associated with exenatide use. Pancreatitis is a rare but serious adverse effect of exenatide, which requires immediate medical attention if suspected.

Correct Answer: A

Rationale: The correct answer is A: Increased risk of bleeding. Apixaban is an anticoagulant medication that works by preventing blood clots. 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.
