A nurse is caring for a client that will receive a diuretic for fluid overload.
Which of the following diuretics act on the loop of Henle?

Spironolactone.

Hydrochlorothiazide.

Furosemide.

Mannitol.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Spironolactone is a potassium-sparing diuretic that acts on the collecting ducts and late distal tubules but not on the loop of Henle.

Choice B rationale

Hydrochlorothiazide is a thiazide diuretic that works on the distal convoluted tubule, not the loop of Henle.

Choice C rationale

Furosemide is a loop diuretic that acts on the ascending limb of the loop of Henle to inhibit sodium and chloride reabsorption, leading to increased urine output.

Choice D rationale

Mannitol is an osmotic diuretic that primarily acts on the proximal tubule and the descending limb of the loop of Henle.

Correct Answer is A

Explanation

Choice A rationale

Brand name medications are typically more expensive because they include costs for research, development, marketing, and patents. They are sold under a trademarked brand name by a specific company, which allows them to charge higher prices.

Choice B rationale

This is incorrect as brand name medications are not less effective than generic medications. Both are required to have the same active ingredients and efficacy by regulatory agencies.

Choice C rationale

While the active ingredients must be the same, the formulation (inactive ingredients) of brand and generic medications can differ, which may affect the drug's characteristics, such as absorption rate.

Choice D rationale

Brand name drugs are usually less prescribed than generics because generics are cheaper and preferred for cost-saving measures. However, in some cases, a brand name might be more widely recognized and prescribed initially.

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.
