A patient diagnosed with deep vein thrombosis asks the nurse, “How does this blood thinner heparin work?” Which response is most accurate?
Heparin makes the blood less thick and easier to flow.
Heparin dissolves the clot and decreases the formation of platelets.
Heparin does not thin the blood; it prevents new clots from forming.
Heparin decreases the number of platelets so the blood flows more easily.
The Correct Answer is C
Choice A rationale
Heparin does not actually thin the blood or make it less thick. Instead, it works by increasing the activity of antithrombin, a protein that inhibits blood clotting. This prevents new clots from forming and existing clots from growing larger.
Choice B rationale
Heparin does not dissolve clots or decrease the formation of platelets. Its primary action is to increase the activity of antithrombin, which in turn inactivates thrombin and factor Xa, two key players in the blood clotting process.
Choice C rationale
This statement is accurate. Heparin does not thin the blood; instead, it prevents new clots from forming and existing clots from growing larger. It does this by increasing the activity of antithrombin, which in turn inactivates thrombin and factor Xa.
Choice D rationale
Heparin does not decrease the number of platelets or make the blood flow more easily. Its primary action is to increase the activity of antithrombin, which in turn inactivates thrombin and factor Xa.

Correct Answer is B
Explanation
Choice A rationale
Hypoglycemia, or low blood sugar, can occur after insulin administration. However, the onset of hypoglycemia is not immediate. Insulin aspart, a rapid-acting insulin, has a peak action time of approximately 1-3 hours after administration. Therefore, assessing the patient for signs and symptoms of hypoglycemia at 0800, one hour after administration, may be too early.
Choice B rationale
Assessing the patient for signs and symptoms of hypoglycemia at 0730, 30 minutes after insulin administration, is too early. The peak action time of insulin aspart is approximately 1-3 hours after administration. Therefore, the nurse should start assessing the patient for signs and symptoms of hypoglycemia closer to the time of peak action.
Choice C rationale
Assessing the patient for signs and symptoms of hypoglycemia at 1130, four and a half hours after insulin administration, may be too late. The peak action time of insulin aspart is approximately 1-3 hours after administration. Therefore, the nurse should start assessing the patient for signs and symptoms of hypoglycemia closer to the time of peak action.
Choice D rationale
Assessing the patient for signs and symptoms of hypoglycemia at 1000, three hours after insulin administration, is within the peak action time of insulin aspart. Therefore, this is the most appropriate time to start assessing the patient for signs and symptoms of hypoglycemia.
Correct Answer is A
Explanation
Choice A rationale
The client diagnosed with peripheral arterial disease has impaired tissue integrity related to ischemic tissue of the legs and feet. This condition is often caused by factors such as physical trauma, thermal factors, chemical injury, infection, nutritional imbalances, fluid imbalances, and altered circulation. The most appropriate outcome to include in the care plan would be for the client to verbalize an understanding of appropriate foot care measures by discharge. This is because maintaining skin integrity and providing effective wound care are crucial aspects of managing this condition. By understanding and implementing appropriate foot care measures, the client can help prevent further tissue damage, promote healing, and improve their overall quality of life.
Choice B rationale
While taking anti-platelet medications can be an important part of managing peripheral arterial disease, it may not directly address the nursing problem of impaired tissue integrity. Anti-platelet medications can help prevent blood clots and improve blood flow, but they do not directly promote wound healing or tissue regeneration.
Choice C rationale
Discussing exercises that promote healing of wounds can be beneficial for the client. However, it’s important to note that exercises should be appropriate for the client’s condition and overall health status. Overexertion or inappropriate exercises could potentially exacerbate the condition and further impair tissue integrity.
Choice D rationale
Recognizing the need for an amputation in the near future can be a realistic outcome for some clients with severe peripheral arterial disease. However, this is typically considered a last resort when all other treatment options have failed. It’s also a drastic measure that can significantly impact the client’s quality of life.
