The nurse is reinforcing discharge instructions to the client with pulmonary sarcoidosis. The nurse knows that the client understands the information if the client verbalizes which early sign of exacerbation?

A. The client is producing large amounts of clear, watery nasal discharge and experiencing postnasal drip: Clear, watery nasal discharge is more indicative of allergic rhinitis rather than sinusitis, which typically presents with thicker, purulent discharge.

B. The client has a history of both tension and vascular headaches and takes prescription migraine medication as needed: While headaches can accompany sinusitis, this option does not directly address symptoms specific to sinusitis, such as nasal congestion or facial pressure.

C. The client has nasal congestion that does not significantly improve with over-the-counter decongestants or antihistamines: Persistent nasal congestion despite the use of decongestants or antihistamines is a common symptom of sinusitis, indicating that the source of the problem may be inflammation or infection in the sinuses.

D.The client regularly uses saline-based nasal washes and a humidifier to clean and moisturize their sinuses: Regular use of these measures suggests the client is taking preventive care of their sinuses but does not necessarily indicate sinusitis.

A. BNP does not promote the synthesis of angiotensin II; instead, it counteracts the effects of the renin-angiotensin-aldosterone system (RAAS) by reducing fluid retention and blood pressure, which is the opposite of what angiotensin II does.
B. BNP does not increase heart rate or cardiac contractility. Its role is primarily in reducing cardiac workload by lowering blood pressure and decreasing fluid volume.
C. BNP does not increase blood pressure; rather, it acts to decrease it by causing vasodilation and inhibiting the effects of aldosterone, which would otherwise increase blood pressure by promoting sodium and water retention.
D. BNP decreases blood pressure by causing vasodilation and promoting the excretion of sodium and water, which reduces blood volume and, consequently, lowers the blood pressure. This is its primary role in cardiovascular regulation, especially in response to heart failure.
