Cheriemel F. Cabildo BSN 2-Y1-5 CRITICAL THINKING QUESTIONS: 1. A 43 year old man is diagnosed with hypertension following an annual physical examination. The patient is thin and states that he engages in fairly regular exercise, but he describes his job as highly stressful. He also has a positive family history for hypertension and stroke. The health care provider initiates therapy with hydrochlorothiazide (Microzide). The patient asks the nurse, “I have high blood pressure, Why do I need a ‘water pill’ to help my blood pressure?” How does hydrochlorothiazide reduce blood pressure? Hydrochlorothiazide inhibits the reabsorption of Na! in the kidney tubule. More Na+ is discharged into the urine when hydrochlorothiazide prevents this reabsorption. Water flows with sodium across the tubule, resulting in a decrease in blood volume and a decrease in blood pressure. In the treatment of hypertension, thiazide diuretics are frequently prescribed. 2. A 78 year-old woman is admitted to the ICU with a diagnosis of heart failure. The nurse administers Furosemide (Lasix) 40 mg IV push. What assessments should the nurse make to determine the effectiveness of this therapy? The nurse should keep a close eye on the fluid level. Because the patient's heart failure is the primary concern, the nurse should check and document the patient's lung sounds, vital signs, and urine output. Hourly output levels may need to be checked according to the patient's condition. Weights should be taken on a daily basis, and any gain of more than 1 kg (2 lb) every 24 hours should be reported to the physician. Edema, as well as the state of her mucous membranes and skin turgor, should be assessed and documented. The nurse would expect a rapid and significant diuresis because furosemide (Lasix) is a loop diuretic. As a result, the nurse should keep an eye
