The nurse is caring for a client with infectious endocarditis. Which information obtained from the health history could have contributed to the development of the disease progress?

A) Be placed in isolation to prevent radiation exposure to others:
Radioactive iodine (I-131) is commonly used to treat thyroid cancer because it targets and destroys thyroid tissue, including any remaining cancerous cells. This treatment involves the administration of a radioactive substance that can be excreted through saliva, urine, and sweat. To minimize radiation exposure to others, patients are often placed in isolation, particularly in a hospital setting, for a period following administration.

B) Avoid consuming any food or fluids for 24 hours prior to the treatment:
While it’s essential for patients to follow specific instructions regarding food and fluid intake, such as avoiding certain foods or fluids that may interfere with absorption or increase the risk of side effects (like dairy products), the patient does not need to avoid all food and fluids for 24 hours after receiving radioactive iodine.

C) Avoid all physical activity for six weeks after the treatment:
While some precautions, such as avoiding close contact with others for a short period of time, may be necessary, avoiding physical activity for six weeks is not usually required. Patients may be advised to take it easy during the initial recovery phase, but they can typically resume normal activities once the initial isolation period is complete and their radiation exposure is below safety thresholds.

D) Discontinue all other medications for a week before treatment:
However, certain medications that affect thyroid function (such as thyroid hormones or antithyroid medications) may need to be adjusted or stopped before treatment to ensure the effectiveness of the radioactive iodine. The specifics would depend on the patient’s condition and the healthcare provider’s instructions.

A) 3% Normal Saline:
Elevated ICP can lead to a life-threatening condition known as cerebral herniation, and it often triggers the Cushing’s triad—widened pulse pressure, bradycardia, and irregular respirations, all of which the nurse has noted. Hypertonic saline (such as 3% Normal Saline) is commonly used to manage increased ICP because it creates an osmotic gradient that draws fluid out of the brain tissue, reducing cerebral edema and lowering ICP. The goal is to reduce swelling and prevent further brain damage.

B) Nitroprusside:
Nitroprusside is a potent vasodilator that is used to treat hypertension and reduce afterload in conditions like heart failure or aortic dissection. However, in this case, nitroprusside is contraindicated because it could cause a drop in systemic blood pressure, which would worsen cerebral perfusion in a patient with elevated ICP.

C) Norepinephrine:
Norepinephrine is a vasopressor used to treat hypotension by increasing systemic vascular resistance and blood pressure. Although norepinephrine may be used to support blood pressure in critically ill patients, in this context of elevated ICP, the priority is to reduce ICP, not to increase blood pressure further. Increasing the systemic vascular resistance with norepinephrine could exacerbate ICP by increasing the volume of blood in the cranium

D) Furosemide:
Furosemide is a loop diuretic that can reduce fluid volume and help treat conditions like edema or heart failure. While furosemide can reduce overall fluid volume, it is not typically used to manage elevated ICP in this context. Diuretics like furosemide may have a role in managing cerebral edema, but they are not as effective as hypertonic saline in rapidly reducing ICP.
