Choice A rationale

Intermittent claudication, which involves limb pain or cramping that generally begins when exercising and improves while resting, is a common symptom in the early stages of PAD5.

Choice B rationale

Foot ulcers are not typically a symptom of the early stages of PAD. They are more likely to occur in the later stages of the disease when blood flow to the extremities is significantly reduced.

Choice C rationale

Pain at rest is not typically a symptom of the early stages of PAD. It is more likely to occur in the later stages of the disease when blood flow to the extremities is significantly reduced.

Choice D rationale

Dependent rubor is not typically a symptom of the early stages of PAD. It is more likely to occur in the later stages of the disease when blood flow to the extremities is significantly reduced.

Choice A rationale

NSAIDs such as ibuprofen are commonly used to manage pain and inflammation. However, they are not typically the first choice for treating phantom limb pain. Phantom limb pain is a complex condition that is thought to involve both peripheral and central mechanisms.

Choice B rationale

Antipyretics such as acetaminophen are used to reduce fever and relieve mild to moderate pain. However, they are not typically used as the primary treatment for phantom limb pain. This type of pain is often resistant to common analgesics, including acetaminophen.

Choice C rationale

Narcotic analgesics such as codeine can be used to manage severe pain. However, they are not typically the first choice for treating phantom limb pain due to the risk of dependency and the fact that this type of pain often does not respond well to opioids.

Choice D rationale

Anticonvulsants such as gabapentin are often used to manage neuropathic pain, including phantom limb pain. Gabapentin works by stabilizing electrical activity in the nervous system and altering the way the nerves send messages to the brain.
