Metastasis is when cancerous cells spread into or invade nearby tissues and can treat malignant tumors.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Metastasis is when cancerous cells spread into or invade nearby tissues and can travel to distant places in the body to form new tumors. This process involves the detachment of cancer cells from the primary tumor, their movement through the bloodstream or lymphatic system, and the establishment of new tumors in other parts of the body.

Choice B rationale

Metastasis specifically involves cancerous cells, not normal cells. Normal cells do not spread and invade other tissues in a way that causes new tumor formation.

Choice C rationale

Metastasis refers to the spread of cancerous cells, not normal cells. Normal cells do not exhibit the same invasive and migratory behaviors as cancerous cells.

Choice D rationale

Metastasis involves the spread of cancerous cells, which can lead to the formation of malignant tumors in distant parts of the body. It does not treat tumors but rather contributes to the progression of cancer.

Correct Answer is A

Explanation

Choice A rationale

Nifedipine is a calcium channel blocker that is effective in treating hypertension and angina. It works by relaxing the blood vessels, which lowers blood pressure and improves blood flow to the heart, reducing chest pain and hypertension.

Choice B rationale

Digoxin is not typically used to treat hypertension. It is primarily used for heart failure and atrial fibrillation to increase the strength of heart muscle contractions and regulate heart rhythm.

Choice C rationale

Heparin is an anticoagulant used to prevent and treat blood clots. It does not directly treat hypertension or angina and is used for conditions like deep vein thrombosis, pulmonary embolism, and during surgeries to prevent clot formation.

Choice D rationale

Captopril is an ACE inhibitor used to treat hypertension and heart failure. While it is effective for lowering blood pressure, it is not primarily used for treating angina compared to medications like nifedipine or other calcium channel blockers.

A. Metoprolol. B. Metformin. C. Lisinopril. D. Nitroglycerin.

Correct Answer is D

Explanation

Choice A rationale

Metoprolol is a beta-blocker used to manage hypertension and other cardiovascular conditions, but it is not a vasodilator used for hypertensive crises.

Choice B rationale

Metformin is an oral hypoglycemic agent used to manage type 2 diabetes and has no role in treating hypertension or hypertensive crises.

Choice C rationale

Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor used to manage hypertension and heart failure, but it is not typically used for hypertensive crises.

Choice D rationale

Nitroglycerin is a potent vasodilator used to rapidly lower blood pressure in hypertensive crises. It works by dilating blood vessels, thus reducing blood pressure effectively. .
