After receiving a vaccination for a communicable disease, the patient was asked to return in 2 to 3 weeks to get an antibody titer and asks why blood testing can’t be done immediately.How should the RN (registered nurse) respond?

Choice A rationale
Administering supplemental oxygen is the priority intervention for a client with COPD who has an oxygen saturation of 88% on room air. This low oxygen saturation indicates hypoxemia, which requires immediate correction to prevent further respiratory distress.
Choice B rationale
Encouraging the client to use an incentive spirometer is important for lung expansion and preventing atelectasis, but it is not the priority intervention in this scenario. The immediate concern is to correct the hypoxemia.
Choice C rationale
Administering a bronchodilator as prescribed is important for managing COPD symptoms, but the priority intervention is to correct the hypoxemia by administering supplemental oxygen.
Choice D rationale
Positioning the client in high Fowler’s position can help improve breathing, but the priority intervention is to correct the hypoxemia by administering supplemental oxygen.

Choice A rationale
Cerebral edema is the swelling of the brain due to fluid accumulation, which can occur after excessive alcohol consumption. However, it is not related to myxedema, which is a condition associated with severe hypothyroidism.
Choice B rationale
The deposit of fatty tissue is associated with conditions like hyperaldosteronism, where there is an excess production of aldosterone. This condition does not cause the characteristic skin changes seen in myxedema.
Choice C rationale
Proliferation of tissue behind the eyes, known as exophthalmos, is common in hyperthyroidism, particularly in Graves’ disease. Myxedema, on the other hand, is related to severe hypothyroidism and involves different pathophysiological mechanisms.
Choice D rationale
Myxedema is characterized by the accumulation of mucopolysaccharides in the skin and other tissues, leading to swelling and thickening of the skin. This condition is a result of severe hypothyroidism and can lead to a myxedema crisis if left untreated.
