Correct Answer is C

Explanation

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.

A. Obtain a pair of heavy-duty gloves to wear for cold exposures. B. Refrain from going outdoors during the winter months. C. Raise the hands above the head to relieve the spasms. D. Use small rubber balls to exercise your hands and fingers daily.

Correct Answer is A

Explanation

Choice A rationale

Raynaud’s disease is a condition that affects blood flow to the extremities, including the fingers and toes, in response to cold temperatures or stress. Wearing heavy-duty gloves during cold exposures can help to keep the hands warm and reduce the risk of a Raynaud’s attack.

Choice B rationale

While avoiding cold temperatures can help to prevent Raynaud’s attacks, it is not always practical or possible for individuals to refrain from going outdoors during the winter months.

Choice C rationale

Raising the hands above the head is not typically recommended to relieve spasms associated with Raynaud’s disease.

Choice D rationale

Using small rubber balls to exercise the hands and fingers daily may be beneficial for some individuals with Raynaud’s disease, but it is not typically the primary recommendation for managing this condition.
