A person with anemia is prescribed erythropoietin subcutaneously. The nurse knows that erythropoietin:

This is because fibromyalgia is a disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep, memory and mood issues. Fibromyalgia often co-exists with other conditions, such as irritable bowel syndrome, chronic fatigue syndrome, migraine and other types of headaches. One of the main symptoms of fibromyalgia is widespread pain that has lasted for at least three months. To be considered widespread, the pain must occur on both sides of your body and above and below your waist. The pain could also be felt in specific areas called tender points. These are places on the body where even light pressure causes pain. There are 18 possible tender points on the body. Having pain in at least 11 of these points is one way to help diagnose fibromyalgia.

Choice A is wrong because chronic ocular pain related to stress, fatigue, and certain triggers is not a typical symptom of fibromyalgia.

Ocular pain is more likely to be caused by other conditions, such as dry eye syndrome, glaucoma, or eye infections.

Choice B is wrong because pain and sensitivity in the upper extremities and neck are not enough to indicate fibromyalgia. The pain must be widespread and affect both sides of the body and above and below the waist. Choice C is wrong because dull joint pain that accompanies physical exertion and which is relieved with rest is not a characteristic of fibromyalgia. The pain associated with fibromyalgia is often described as a constant dull ache that does not improve with rest. It may also be accompanied by other symptoms, such as fatigue, cognitive difficulties, and sleep problems.

This is because people with COPD are more likely to catch respiratory infections such as colds, flu and pneumonia, which can worsen their symptoms and cause further lung damage. An influenza vaccine can help prevent flu and reduce the risk of complications.

Choice B. A broad-spectrum antibiotic is wrong because antibiotics are only effective against bacterial infections, not viral ones. Antibiotics are usually prescribed for COPD exacerbations caused by bacterial infections, but not for prevention.

Choice C. A bronchodilator is wrong because bronchodilators are medications that relax the muscles around the airways and make breathing easier. They are used to treat the symptoms of COPD, but they do not prevent respiratory infections.

Choice D. A corticosteroid is wrong because corticosteroids are anti inflammatory drugs that reduce swelling and mucus production in the airways. They are also used to treat the symptoms of COPD, but they do not prevent respiratory infections. In fact, long-term use of corticosteroids may increase the risk of infections by suppressing the immune system.
