Pharmacology - Exam 2 - ATI & NCLEX QuestionsThe nurse knows that diuretics mostly affect which function of the kidneys? a. cleansing and maintenance of extracellular fluid volume b. maintenance of acid-base balance c. excretion of metabolic waste d. elimination of foreign substances - correct answer a. cleansing and maintenance of extracellular fluid volume Most diuretics block sodium and chloride reabsorption, thus affecting the maintenance of extracellular fluid volume. The nurse plans to closely monitor for which clinical manifestation after administering furosemide (lasix)? a. decreased pulse b. decreased temperature c. decreased BP d. decreased respiratory rate - correct answer c. decreased BP High-ceiling loop diuretics, such as furosemide, are the most effective diuretic agents. They produce more loss of fluid and electrolytes than any others. A sudden loss of fluid can result in decreased blood pressure. When blood pressure drops, the pulse probably will increase rather than decrease. Lasix should not affect respiration or temperature. The nurse should also closely monitor the patient's potassium level.
