The nurse is preparing to administer hydration via an intravenous route to a client.
The nurse understands that the patient needs an isotonic solution.
Which of the following options is considered an isotonic solution?

Choice A rationale

Cancer is characterized by uncontrolled cell growth and the ability to spread or metastasize to other parts of the body, disrupting normal bodily functions.

Choice B rationale

This statement is incorrect because cancer involves uncontrollable cell growth, contrary to what is stated.

Choice C rationale

This statement is incorrect as cancer cells do grow and can spread to other parts of the body.

Choice D rationale

This statement is not accurate as cancer involves specific characteristics that Choices B and C do not describe correctly.

Choice A rationale: Furosemide is a loop diuretic used to reduce fluid overload in CHF patients. However, it can exacerbate electrolyte imbalances, particularly hypokalemia. Since the client is already experiencing muscle spasms and has low calcium levels, additional diuretic therapy could worsen these symptoms.

Choice B rationale: Metoprolol is a beta-blocker used to manage hypertension and heart rate in CHF patients. While beneficial for blood pressure control, it does not address the immediate issue of muscle spasms and constipation the client is experiencing.

Choice C rationale: Potassium chloride is indicated to address potential hypokalemia, which may be causing the client's muscle spasms. CHF patients on diuretics often experience low potassium levels, so supplementation is crucial to prevent complications and alleviate symptoms.

Choice D rationale: Acetaminophen is an analgesic and antipyretic, useful for pain and fever management. However, it does not address the client's reported muscle spasms, which are likely related to electrolyte imbalances.
