The nurse is teaching a client who is diagnosed with peripheral arterial disease about the benefits of walking to exercise. What information should the nurse reinforce with this client?

Continue walking to the point of pain

Do not walk if a leg ulcer develops

Elevate the feet for 30 minutes after walking

Avoid exercise that places the feet in a dependent position

Answer and Explanation

The Correct Answer is A

A.   Clients with PAD often experience claudication (pain in the legs due to inadequate blood flow) during exercise. They should be encouraged to walk to the point of pain, then rest until the pain subsides, and then continue walking. This approach can improve circulation over time.
B.   While it’s crucial to monitor leg ulcers, exercise can still be beneficial unless advised otherwise by a healthcare provider. Walking can promote circulation, which is important for healing. However, if a leg ulcer is present, the client should consult their healthcare provider about appropriate activity levels.
C.   While elevating the feet can help reduce swelling, it's generally more beneficial for clients with PAD to keep their legs in a dependent position after walking. This position encourages blood flow to the legs, which can help alleviate symptoms and improve circulation.
D.   Exercise that encourages movement and maintains blood flow to the legs is important for those with PAD. While certain positions may exacerbate symptoms, exercises like walking should be encouraged. Keeping the feet in a dependent position can help with blood flow post-exercise.

Correct Answer is C

Explanation

A. This option refers to the pathogens themselves (infectious agents) and the places where they live and multiply (reservoirs). Washing hands does not directly affect the relationship between these two.
B. The portal of exit refers to how an infectious agent leaves the reservoir (e.g., through feces, urine, etc.), and the mode of transmission refers to how the agent spreads (e.g., via hands, surfaces, etc.). Handwashing helps reduce the potential for pathogens to be transmitted but does not specifically break the chain between these two links.
C. Handwashing after using the bathroom effectively breaks the chain of infection by interrupting the mode of transmission (direct contact with contaminated hands) and preventing pathogens from entering another person's body (portal of entry). By cleaning hands, the risk of spreading infectious agents to others is significantly reduced.

D. This option refers to the relationship between a person who is vulnerable to infection (susceptible host) and the pathogens that cause disease (infectious agents). While handwashing helps prevent infections, it primarily acts on the transmission aspect rather than directly affecting susceptibility.

Correct Answer is ["6.2"]

Explanation

Total daily dose in mg:
1.5 grams/day = 1500 mg/day Dose per administration in mg:
1500 mg/day ÷ 3 doses/day = 500 mg/dose Volume to be administered per dose in mL:
(500 mg/dose) / (400 mg/5 mL) = 6.25 mL/dose
Rounding to the nearest tenth, the nurse will administer 6.2 mL per dose.
