A client is to begin a 6-month course of therapy with isoniazid. The nurse should plan to provide which information to the client?
Avoid vitamin supplements during therapy.
Drink alcohol in small amounts only.
Report yellow eyes or skin immediately.
Increase intake of Swiss or aged cheeses.
The Correct Answer is C
A. Avoid vitamin supplements during therapy: This is not generally advised for isoniazid therapy. In fact, vitamin B6 supplements are often recommended to prevent peripheral neuropathy caused by isoniazid.
B. Drink alcohol in small amounts only: Alcohol can increase the risk of liver toxicity when taking isoniazid. It is typically advised to avoid alcohol altogether during treatment.
C. Report yellow eyes or skin immediately: Isoniazid can cause liver toxicity, which can lead to jaundice (yellowing of the eyes and skin). This is a serious side effect and should be reported immediately to prevent further liver damage.
D. Increase intake of Swiss or aged cheeses: This recommendation is not related to isoniazid therapy. Aged cheeses are more relevant to patients on monoamine oxidase inhibitors (MAOIs) due to tyramine content.

Correct Answer is D
Explanation
A. Impaired carbon dioxide elimination due to shunting: In ARDS, shunting can impair oxygenation but not directly carbon dioxide elimination. Shunting refers to blood flow through areas of the lung that are not ventilated properly, primarily affecting oxygenation.
B. Decreased pulmonary arterial pressure due to ventilation-perfusion (V/Q) mismatch: ARDS is typically associated with increased, not decreased, pulmonary arterial pressure due to the inflammatory process and reduced lung compliance. V/Q mismatch in ARDS usually results in elevated pulmonary arterial pressure.
C. Hypoxemia due to dead space: ARDS hypoxemia results from impaired gas exchange in damaged alveoli rather than dead space, which is more related to ventilation without perfusion.
D. Decreased pulmonary compliance due to stiffness: ARDS is characterized by decreased pulmonary compliance, which is due to the stiffening of lung tissue from inflammation and edema. This stiffness makes lung expansion more difficult and is a key feature of ARDS.
Correct Answer is D
Explanation
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.
