Metastasis is when normal cells spread into or invade nearby tissues but do not travel to distant places in the body.

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

Vitamin K1 is used as an antidote for warfarin toxicity because it helps in the synthesis of clotting factors, reversing the anticoagulant effects of warfarin.

Choice B rationale

Protamine sulfate is used to counteract the effects of heparin, not warfarin.

Choice C rationale

Heparin is an anticoagulant and would worsen bleeding if given in the case of warfarin toxicity.

Choice D rationale

Digibind is used to treat digoxin toxicity and has no role in reversing the effects of warfarin. .

A. This medication is also used to treat malignant hyperthermia. B. This medication is used to treat muscle spasticity. C. This medication can be used for pain management. D. This medication helps in reducing muscle stiffness.

Correct Answer is A

Explanation

Choice A rationale

Dantrolene is used to treat malignant hyperthermia, a rare life-threatening condition usually triggered by certain anesthetics or muscle relaxants.

Choice B rationale

Although dantrolene is used to treat muscle spasticity, the indication in this question is specifically about malignant hyperthermia, making this choice not the most appropriate.

Choice C rationale

Dantrolene is not typically used for general pain management. Its primary use is in malignant hyperthermia and severe spasticity.

Choice D rationale

While reducing muscle stiffness can be a result of its spasticity treatment, malignant hyperthermia is a more specific and critical use of dantrolene.
