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.

Answer and Explanation

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 A

Explanation

Step 1 is to understand that a blood glucose level of 50 mg/dL is considered hypoglycemic. Immediate treatment is necessary to raise the blood glucose level.

Step 2 is to follow the 15-15 rule for treating hypoglycemia, which recommends consuming 15 grams of carbohydrates and then checking blood glucose levels after 15 minutes. Four ounces of orange juice contains about 15 grams of carbohydrates and can quickly raise blood glucose levels.

A. “My feet look reddish when I put them down.”. B. “I noticed that the hair on my feet and legs is gone.”. C. “My legs were so cold I had to put a heating pad on them.”. D. “My legs start to hurt when I walk to get my mail.”.

Correct Answer is C

Explanation

Choice A rationale

Reddish feet when put down could be a sign of dependent rubor, a condition that occurs due to peripheral arterial disease (PAD). When the legs are in a dependent (downward) position, gravity aids in delivering blood to the area, causing a reddish color. However, this is a common symptom of PAD and does not require immediate intervention.

Choice B rationale

Loss of hair on the feet and legs is another symptom of PAD1. This happens because inadequate blood flow deprives the hair follicles of the nutrients they need to grow. While this symptom indicates worsening PAD, it does not warrant immediate intervention.

Choice C rationale

Applying a heating pad to cold legs could lead to burns because PAD can cause loss of sensation in the legs. This warrants immediate intervention to prevent injury.

Choice D rationale

Leg pain during walking, also known as claudication, is a common symptom of PAD1. This happens because the muscles are not getting enough oxygen due to reduced blood flow.

However, this symptom does not require immediate intervention but should be evaluated further.
