A nurse is caring for a client who is newly diagnosed with breast cancer.
The client asks the nurse, "What is the difference between benign and malignant tumors?" Which of the following statements should the nurse include in her response to the client?

Choice A rationale

Ciprofloxacin is a bactericidal antibiotic that works by inhibiting DNA gyrase, an enzyme necessary for DNA replication in bacteria. This prevents bacterial cells from replicating and ultimately leads to their death.

Choice B rationale

Ciprofloxacin does not accelerate bacterial growth; instead, it inhibits growth by preventing DNA replication.

Choice C rationale

Ciprofloxacin is not a diuretic. Diuretics work on the kidneys to increase urine production, but ciprofloxacin targets bacterial DNA replication.

Choice D rationale

Ciprofloxacin is not a beta-blocker and does not lower heart rate or blood pressure. Beta-blockers work by blocking beta-adrenergic receptors in the heart.

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. .
