A nurse knows that the liver is a common site for metastasis from other primary cancers due to:

A. Blowing your nose hard when the dizziness first begins is not a recommended action for Meniere's disease. Blowing the nose forcefully can increase pressure in the ears and potentially worsen symptoms of vertigo, not alleviate them.
B. Laying down and keep your head still is a recommended strategy for managing vertigo in Meniere's disease. Resting and keeping the head still can help reduce the sensation of spinning or dizziness, providing some relief. Movement can trigger or worsen vertigo, so staying still is an effective way to reduce symptoms.
C. While salt intake is often restricted in Meniere's disease due to its potential to increase fluid retention in the inner ear, potassium supplements are generally not a standard recommendation. Dietary changes should be discussed with a healthcare provider.
D. Hydration is important for overall health, but this is not a specific recommendation for reducing vertigo in Meniere's disease. It may help with general wellness, but it won't directly alleviate the symptoms of vertigo associated with the condition.

A. Urticaria (hives) is not a common side effect of radiation therapy. The skin should be examined for localized radiation-induced skin changes, such as erythema or dryness, rather than generalized urticaria.
B. Radiation therapy can weaken the immune system, increasing the risk of infection. The nurse should monitor for signs of infection, especially in areas affected by radiation, as the skin and mucous membranes can become more vulnerable.
C. Low hemoglobin is not a direct or immediate concern related to radiation therapy for lung cancer. However, it could occur if the patient experiences bone marrow suppression, but this is not typically the primary concern for radiation therapy to the lung.
D. Xerostomia (dry mouth) is more commonly associated with radiation therapy to the head and neck area. Radiation to the lungs generally does not affect salivary glands, so monitoring for xerostomia is not necessary in this case.
