A nurse is reinforcing teaching with a client who has anemia and has a prescription for ferrous sulfate. Which of the following foods should the nurse recommend that the client consume to increase the absorption of this medication?

The correct answer is choice C: Blood pressure change from 118/78 mm Hg to 86/50 mm Hg.

Choice C rationale: A significant drop in blood pressure can indicate various serious conditions, such as shock, hemorrhage, or a severe infection. The nurse should assess the client further and intervene as necessary to prevent complications.

Choice A rationale: The change in temperature may indicate the onset of a fever and requires further assessment, but it is not as immediately concerning as the sudden drop in blood pressure.

Choice B rationale: The change in respiratory rate could be a result of factors like pain, anxiety, or exercise. While it warrants further assessment, it is not as critical as the blood pressure change.

Choice D rationale: The heart rate change may be a response to medications, rest, or other factors. It should be monitored and assessed, but the priority finding is the blood pressure change, which may indicate a more severe underlying issue.

The nurse should perform neurovascular checks of the affected extremity every 2 hours to monitor for any signs of compartment syndrome or impaired circulation. It is important to assess for the five Ps: pain, pulse, pallor, paresthesia, and paralysis. Using a hair dryer to relieve itching can cause burns and is not a recommended intervention. Positioning the fractured arm below the level of the client's heart can increase swelling and exacerbate pain. Immobilizing the client's fingers using a hand splint is not indicated unless there is a finger fracture or injury.

Choice A (Use a hair dryer to blow hot air into the cast to relieve itching) is not an answer because it can cause burns and is not a recommended intervention.

Choice C (Position the fractured arm below the level of the client's heart) is not an answer because it can increase swelling and exacerbate pain.

Choice D (Immobilize the client's fingers using a hand splint) is not an answer because it is not indicated unless there is a finger fracture or injury.
