A patient has recently started ferrous sulfate 500 mg by mouth two times per day for anemia. Which of the following data would indicate to the nurse that the therapy is successful?

Choice A reason: The nurse would include the question of whether the client ever uses oxygen, as this can be related to erythema. Erythema is a condition where the skin becomes red and inflamed due to increased blood flow or irritation. ¹ One possible cause of erythema is oxygen toxicity, which is a condition where the lungs and tissues are damaged by exposure to high levels of oxygen. ² The nurse would ask the client if they ever use oxygen, especially at high concentrations or for long periods of time, as this can increase the risk of oxygen toxicity and erythema.

Choice B reason: The nurse would not include the question of how many pillows the client sleeps on, as this is not related to erythema. The number of pillows the client sleeps on may indicate the presence of other conditions, such as sleep apnea, acid reflux, or heart failure, but not erythema. ³ The nurse would ask the client about their sleeping habits and preferences, but not specifically about the number of pillows they use.

Choice C reason: The nurse would not include the question of whether the client feels rested after sleeping, as this is not related to erythema. The feeling of restfulness after sleeping may indicate the quality and quantity of sleep the client gets, which can affect their overall health and well-being, but not erythema. The nurse would ask the client about their sleep patterns and problems, but not specifically about their feeling of restfulness.

Choice D reason: The nurse would not include the question of how far the client can walk before feeling short of breath, as this is not related to erythema. The distance the client can walk before feeling short of breath may indicate the level of physical activity and fitness the client has, which can affect their cardiovascular and respiratory health, but not erythema. The nurse would ask the client about their exercise habits and limitations, but not specifically about their walking distance.

Choice A reason: I will call dietary to bring you breakfast is not the best response by the nurse. This response may imply that the nurse is willing to compromise the test results or the client's safety by allowing them to eat before the test. The nurse should explain the rationale for fasting and offer the client some water or ice chips if allowed.

Choice B reason: Food may interact with the dye that is used for the test is not the best response by the nurse. This response may be partially true, but it is not specific or clear enough to justify the need for fasting. The nurse should explain that food can affect the absorption and distribution of the radioactive tracer that is injected into the bloodstream for the test, and that eating can also interfere with the quality of the images.

Choice C reason: I will ask the health care provider if the test can be rescheduled is not the best response by the nurse. This response may suggest that the nurse is not confident or knowledgeable about the test protocol or the client's condition. The nurse should explain the importance and urgency of the test and reassure the client that they will be able to eat after the test is done.

Choice D reason: The procedure is usually completed on an empty stomach is the best response by the nurse. This response is accurate and concise, and it informs the client of the standard preparation for the test. The nurse should also provide more details about the test procedure and the expected duration, and answer any questions or concerns that the client may have.
