A female client starts a new prescription, oxybutynin, for symptoms of an overactive bladder. The client tells the nurse that she is training to run in a half-marathon. Which instruction should the nurse emphasize?

Keep skin and eyes covered to protect from sun injury.

Avoid crowds to help prevent acquiring infections.

Wear padding to protect from bruising if a fall occurs.

Take measures to avoid dehydration and overheating.

Answer and Explanation

The Correct Answer is D

Choice A Reason:

While keeping skin and eyes covered to protect from sun injury is generally good advice, it is not specifically related to the use of oxybutynin. Oxybutynin can reduce sweating, which increases the risk of overheating and dehydration, especially during physical activities like running a half-marathon. Therefore, this advice, while useful, is not the most critical in this context.

Choice B Reason:

Avoiding crowds to help prevent acquiring infections is important for overall health, especially for individuals with compromised immune systems. However, this advice is not directly related to the use of oxybutynin or the specific risks associated with its use during physical exercise. The primary concern with oxybutynin is its effect on sweating and body temperature regulation.

Choice C Reason:

Wearing padding to protect from bruising if a fall occurs is a precaution that might be relevant for individuals at risk of falls or injuries. However, this advice does not address the specific risks associated with oxybutynin use during physical exercise. The main concern is the potential for overheating and dehydration due to reduced sweating.

Choice D Reason:

Taking measures to avoid dehydration and overheating is the most critical instruction for a client using oxybutynin while training for a half-marathon. Oxybutynin can decrease sweating, making it harder for the body to cool down during exercise. This can lead to heat stroke or severe dehydration. The nurse should emphasize the importance of staying hydrated, taking breaks, and avoiding excessive heat to prevent these serious complications.

Correct Answer is D

Explanation

Choice A reason:

Requesting a prescription to change the route of administration and use the available heparin is not appropriate. Low molecular weight heparin (LMWH) and unfractionated heparin (UFH) are not interchangeable on a unit-for-unit basis. They have different pharmacokinetics and dosing requirements. Changing the route without proper guidance can lead to incorrect dosing and potential complications.

Choice B reason:

Calculating and administering the equivalent dose of the available low molecular weight heparin is incorrect. LMWH and UFH have different dosing protocols and are not directly interchangeable. Administering LMWH instead of UFH without proper conversion and guidance can result in inappropriate anticoagulation.

Choice C reason:

Diluting the available heparin in 250 ml of normal saline solution prior to IV administration is not appropriate. The prescription specifies heparin 5000 units IV STAT, which indicates an immediate need for intravenous administration. Diluting and administering it in this manner does not align with the urgency of the order.

Choice D reason:

Advising the pharmacy of the need to deliver a vial of heparin to the nursing unit immediately is the correct action. This ensures that the client receives the prescribed medication in the correct form and dosage as ordered by the healthcare provider. It is crucial to follow the specific instructions for heparin administration to ensure patient safety and effective anticoagulation.

A. If severe hypoglycemia occurs. B. Before meals to prevent hyperglycemia. C. When unable to eat during sick days. D. At the onset of signs of diabetic ketoacidosis.

Correct Answer is A

Explanation

Choice A Reason:

Glucagon is a hormone used to treat severe hypoglycemia (low blood sugar) in individuals with diabetes. Severe hypoglycemia can be life-threatening and requires immediate treatment to raise blood sugar levels. Glucagon works by stimulating the liver to release stored glucose into the bloodstream. It is crucial for clients and their families to recognize the signs of severe hypoglycemia, such as confusion, unconsciousness, or seizures, and to administer glucagon promptly.

Choice B Reason:

Administering glucagon before meals to prevent hyperglycemia is incorrect. Glucagon is not used to prevent high blood sugar levels; it is specifically used to treat low blood sugar levels. Preventing hyperglycemia typically involves insulin administration and dietary management, not glucagon.

Choice C Reason:

While managing blood sugar levels during sick days is important, glucagon is not used for this purpose. Clients are usually advised to monitor their blood sugar levels more frequently and adjust their insulin doses as needed during illness. Glucagon is reserved for emergency situations involving severe hypoglycemia.

Choice D Reason:

Glucagon is not used to treat diabetic ketoacidosis (DKA). DKA is a serious complication of diabetes that requires immediate medical attention and is treated with insulin, fluids, and electrolytes. Administering glucagon would not address the underlying issues of DKA and could potentially worsen the condition.
