The nurse is teaching a patient to wash their hands after using the bathroom as an attempt to break the chain of infection.
Between which two links in the chain of infection does this action intervene?

Infectious agent and reservoir.

Mode of transmission and portal of entry.

Susceptible host and infectious agent.

Portal of exit and mode of transmission.

Answer and Explanation

The Correct Answer is D

Choice A rationale

The infectious agent is the pathogen that causes the disease, and the reservoir is where the infectious agent lives and multiplies. Hand washing does not directly intervene between these two links.

Choice B rationale

The mode of transmission is how the infectious agent travels to other people and places, and the portal of entry is the route by which an infectious agent enters a new host. Hand washing does not directly intervene between these two links.

Choice C rationale

The susceptible host is a person who is vulnerable to the disease, and the infectious agent is the pathogen that causes the disease. Hand washing does not directly intervene between these two links.

Choice D rationale

The portal of exit is the route by which an infectious agent escapes or leaves the reservoir, and the mode of transmission is how the infectious agent travels to other people and places. Hand washing directly intervenes between these two links by removing the infectious agent from the hands (portal of exit) and preventing its transmission to other people or surfaces.

Correct Answer is C

Explanation

Choice A rationale

While it might seem that smaller doses of both drugs could be used when they are prescribed together, this is not the primary reason for using heparin and warfarin together. Both drugs have different mechanisms of action and are used for their unique therapeutic effects.

Choice B rationale

The combination of heparin and warfarin does not facilitate thrombolysis more quickly. Thrombolysis is the process of breaking down clots, and while these medications can prevent the formation of new clots, they do not actively break down existing ones.

Choice C rationale

Heparin and warfarin are often used together in the treatment of thrombophlebitis because they provide different benefits. Heparin acts quickly to prevent further clotting and allows the body to naturally break down existing clots. Warfarin, on the other hand, takes several days to become effective. Therefore, heparin is used to provide immediate anticoagulation until the warfarin becomes effective.

Choice D rationale

While it’s true that the combination of heparin and warfarin provides immediate anticoagulation, this is primarily due to the action of heparin. Warfarin takes several days to become effective, so it does not contribute to the immediate anticoagulant effect.

A. 0640 B. 0650 C. 0700 D. 0710

Correct Answer is A

Explanation

The correct answer is Choice A. Insulin lispro is a fast-acting insulin that starts to work about 15 minutes after injection. Therefore, the client should eat within 15 minutes of taking the insulin to prevent hypoglycemia. So, if the client takes the insulin at 0630, they should start eating at 06404
