Which assessment data indicated to the nurse that a client is having an anaphylactic reaction to a medication?

Restless legs syndrome is a condition that causes an uncomfortable sensation in the legs and an uncontrollable urge to move them. Melatonin is a natural hormone that helps regulate the sleep-wake cycle and can be used as a sleep aid. Therefore, when evaluating the effectiveness of melatonin in an older adult client with restless legs syndrome, the nurse should assess the client's sleep patterns to determine if the herb is improving their ability to fall and stay asleep.

Assessing anxiety level (a) may be useful in other contexts, but it is not directly relevant to evaluating the effectiveness of melatonin for restless legs syndrome. Observing for peripheral edema (b) and palpating pedal pulse volume (d) are important assessments in clients with peripheral vascular disease or other circulatory disorders, but they are not directly related to restless legs syndrome or the use of melatonin.

Epoetin alfa is a medication that stimulates the production of red blood cells and is commonly used to treat anemia in patients with chronic kidney disease. Hemoglobin level is the most important parameter to monitor the effectiveness of epoetin alfa therapy. An increase in hemoglobin level indicates an improvement in the patient's anemia and suggests that the medication is effective.

While options a, b, and d are also important considerations in the management of anemia, they do not provide a definitive indication of the effectiveness of epoetin alfa therapy. Reports of increased energy levels and decreased fatigue can be subjective and influenced by many factors. Taking concurrent iron therapy without adverse effects is important to support the production of red blood cells but does not confirm the effectiveness of epoetin alfa. Increased consumption of iron-rich foods can be helpful in managing anemia, but it does not provide a direct indication of the effectiveness of epoetin alfa therapy.
