Correct Answer is A

Explanation

A. Red-colored urine: Rifampin, when taken orally or intravenously, can cause red discoloration of bodily fluids, including urine, sweat, saliva, and tears. This is a common and harmless side effect of the medication. Clients should be informed about this potential discoloration to avoid unnecessary concern.

B. Black-colored stools: Black-colored stools are not an expected side effect of rifampin.

C. Staining of teeth: While rifampin can cause staining of contact lenses, it is not associated with tooth discoloration.

D. Constipation: Constipation is not a common side effect of rifampin. Gastrointestinal side effects may include nausea, vomiting, and abdominal pain.

A. The pain persists with rest and organic nitrates. B. The pain usually lasts longer than 20 min. C. Exertion and anxiety can trigger the pain. D. The pain often radiates to the jaw or the back.

Correct Answer is C

Explanation

A. The pain persists with rest and organic nitrates: This statement is incorrect. Anginal pain typically improves with rest and can be relieved by the administration of organic nitrates.

B. The pain usually lasts longer than 20 min: This statement is incorrect. Anginal pain is often brief and lasts for a few minutes, typically less than 20 minutes.

C. Exertion and anxiety can trigger the pain: This is the correct answer. Anginal pain is often triggered by activities that increase the workload of the heart, such as exertion or emotional stress (anxiety). These triggers lead to an increased demand for oxygen by the heart muscle, which may exceed the compromised blood supply, resulting in angina.

D. The pain often radiates to the jaw or the back: This statement is correct. Anginal pain may radiate to the jaw, back, shoulder, arm, or neck. The radiation of pain is a characteristic feature of angina.
