A nurse is preparing to administer clonidine 0.3 mg at bedtime to a patient. The available amount is clonidine 0.1 mg/tablet.

How many tablets should the nurse administer per dose?

Choice A rationale

Bacteria are not a known risk factor for osteoarthritis. Osteoarthritis is a degenerative joint disease, not an infectious disease caused by bacteria.

Choice B rationale

Diuretics are a type of medication used to remove excess water from the body. They are not a known risk factor for osteoarthritis.

Choice C rationale

Aging is a risk factor for osteoarthritis. The risk of developing osteoarthritis increases with age.

Choice D rationale

Obesity is a significant risk factor for osteoarthritis. Excess weight puts additional stress on weight-bearing joints, such as the knees and hips, which can lead to the development of osteoarthritis.

Choice A rationale

Phosphate levels are not directly affected by spironolactone. Spironolactone is a potassium- sparing diuretic and does not typically affect phosphate levels.

Choice B rationale

Decreased potassium level is not typically expected in a patient taking spironolactone. Spironolactone is a potassium-sparing diuretic, meaning it can actually lead to increased potassium levels. However, in the context of liver failure and ascites, other factors may influence potassium levels.

Choice C rationale

Chloride levels are not directly affected by spironolactone. Spironolactone primarily affects the balance of potassium and sodium in the body.

Choice D rationale

Sodium levels could potentially be decreased in a patient taking spironolactone, as it can cause the body to lose sodium. However, in the context of liver failure and ascites, sodium levels are often carefully managed.
