A nurse caring for a patient who suffered a severe sprain and has an order for a cold pack application to the injured area would prevent patient injury by:.

Choice A rationale:
Chronic pain is defined as pain that lasts for an extended period, typically more than 3-6 months, and is often associated with conditions like arthritis. Severe arthritis is a common cause of chronic pain, as it persists over a long duration.
Choice B rationale:
Episodic pain refers to pain that occurs intermittently, with pain-free intervals in between. This term is not appropriate for describing the continuous discomfort associated with severe arthritis.
Choice C rationale:
Phantom pain is the sensation of pain in a body part that has been amputated or lost, which is not relevant to a patient with severe arthritis.
Choice D rationale:
Acute pain is typically short-term and results from a specific injury or illness. It is not the appropriate term for describing the long-lasting pain associated with severe arthritis.

Choice A rationale:

Post-herpetic neuralgia. Post-herpetic neuralgia is a neuropathic pain that occurs as a complication of shingles (herpes zoster) and is characterized by severe, burning, or shooting pain in the affected area. It is not an example of nociceptive pain.

Choice B rationale:

Diabetic neuropathy. Diabetic neuropathy is another example of neuropathic pain and is caused by damage to the nerves due to diabetes. It typically presents as aching, burning, or tingling sensations and is not considered nociceptive pain.

Choice C rationale:

Phantom limb pain. Phantom limb pain is also a neuropathic pain that occurs after the amputation of a limb. Patients perceive pain or discomfort in the missing limb. It is not classified as nociceptive pain.

Choice D rationale:

Strained muscle. Strained muscle pain is a classic example of nociceptive pain. Nociceptive pain arises from the activation of pain receptors (nociceptors) due to tissue damage or inflammation. In the case of a strained muscle, the pain results from physical injury or overuse of the muscle, making it a nociceptive pain. Nociceptive pain can be further categorized into somatic and visceral pain. Somatic pain, as in the case of a strained muscle, arises from musculoskeletal structures, and it is typically well-localized, sharp, and aching. Understanding the nature of pain is essential for effective pain management and treatment selection. .
