Which finding about a patient with polycythemia vera is most important for the nurse to report to the health care provider?

A. "Dietary supplements have not been tested and approved by the government." While this statement may be true, it is not directly related to the potential interaction between dietary supplements and nitroglycerin.

B. "Dietary supplements may be expensive and are not typically covered by insurance." While cost considerations are important, they are not directly related to the potential interaction
between dietary supplements and nitroglycerin.
C. "There is not enough evidence that dietary supplements are effective for erectile dysfunction."
While this statement may be true, it is not directly related to the potential interaction between dietary supplements and nitroglycerin.
D. "Dietary supplements can cause a drug-drug interaction with nitrates." Nitroglycerin is a medication commonly used for angina, and it interacts with erectile dysfunction medications
such as sildenafil (Viagra) due to its vasodilatory effects, potentially causing severe hypotension.
Therefore, it is crucial for the nurse to educate the client about the risk of interactions between dietary supplements and nitroglycerin.

A. Risk for Injury related to compromised blood volume is not the most appropriate nursing diagnosis for a patient with sickle cell disease in crisis. While patients may experience anemia and blood volume loss during a crisis, the primary concern is tissue perfusion due to vascular occlusion by sickled cells.
B. Risk for Deficient Fluid Volume related to infection is not directly related to the pathophysiology of sickle cell disease or sickle cell crisis.
C. Ineffective Airway Clearance related to sickled cells may be a concern for patients with sickle cell disease, especially during acute chest syndrome, but it is not the primary nursing diagnosis for a patient admitted for sickle cell crisis.
D. Ineffective Tissue Perfusion related to vascular occlusion is the most appropriate nursing diagnosis for a patient with sickle cell disease in crisis. Sickle cell crisis involves the occlusion of blood vessels by sickled cells, leading to impaired tissue perfusion and potential organ damage.
