A nurse is providing an in-service about cancer.Which of the following statements is true regarding metastasis?
Metastasis is when cancerous cells spread into or invade nearby tissues and can travel to distant places in the body to form new tumors.
Metastasis is when normal cells spread into or invade nearby tissues and can travel to distant places in the body but do not form tumors.
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.
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
Lactated Ringers (LR) is an isotonic solution, which means it has the same osmolarity as blood plasma. This property makes LR suitable for rehydrating patients without causing a significant shift of fluids between compartments, maintaining the balance of electrolytes.
Choice B rationale
0.45% Sodium Chloride is a hypotonic solution, meaning it has a lower osmolarity compared to blood plasma. This type of solution would cause fluid to move into cells, potentially leading to cellular swelling.
Choice C rationale
Dextrose in Lactated Ringers is a hypertonic solution because the added dextrose increases the osmolarity. This solution can cause fluid to shift out of cells, leading to cellular shrinkage, which is not ideal for rehydration.
Choice D rationale
None of the above is incorrect because Lactated Ringers (LR) is indeed an isotonic solution.
Correct Answer is A
Explanation
Choice A rationale
Metoprolol is a beta-blocker that is commonly used to manage hypertension and control heart rate. It works by blocking beta-adrenergic receptors, which decreases heart rate and blood pressure.
Choice B rationale
Enoxaparin is an anticoagulant used to prevent and treat deep vein thrombosis and pulmonary embolism, not primarily to manage hypertension.
Choice C rationale
Heparin is an anticoagulant used to prevent and treat blood clots, and it is not indicated for the management of hypertension.
Choice D rationale
Simvastatin is a lipid-lowering medication used to manage high cholesterol levels and is not used to manage hypertension.
