Complete Chapter Questions With Answers
Sample Questions Are Posted Below
| 1. | The physician has ordered the patient hydrochlorothiazide. What assessment should the nurse make before administering the first dose of hydrochlorothiazide? | |
| A) | Pulse rate | |
| B) | Hemoglobin level | |
| C) | Sulfonamide allergy | |
| D) | Neutrophil level | |
| Ans: | C | |
| Feedback: | ||
| Thiazide diuretics must be used cautiously in patients allergic to sulfonamide drugs because there is a known cross-sensitivity of some sulfonamide-allergic patients to sulfonamide nonantibiotic. It is not imperative to assess pulse, hemoglobin, or neutrophil levels. | ||
| 2. | A patient has edema of the lower extremities and abdomen. What is the reason for administering a stronger diuretic than a thiazide diuretic to this patient? | |
| A) | A thiazide diuretic will reabsorb potassium in the distal tubule. | |
| B) | A thiazide diuretic will be ineffective for immediate diuresis. | |
| C) | A thiazide diuretic will provide peak effects in 2 hours. | |
| D) | A thiazide diuretic will be excreted in more than 72 hours. | |
| Ans: | B | |
| Feedback: | ||
| Thiazide diuretics are ineffective when immediate diuresis is required. A thiazide diuretic acts to reabsorb sodium, not potassium, in the distal convoluted tubule. A thiazide diuretic reaches its peak in 4 to 6 hours. A thiazide diuretic is excreted in 72 hours maximum. | ||
| 3. | A patient is admitted to the hospital with a diagnosis of heart failure. The patient is ordered to receive furosemide (Lasix) 40 mg IV. How soon after administration should the nurse expect to see evidence of diuretic effects? | |
| A) | 1 minute | |
| B) | 5 minutes | |
| C) | 30 minutes | |
| D) | 2 hours | |
| Ans: | B | |
| Feedback: | ||
| After IV administration, diuretic effects occur within 5 minutes. The diuretic effect is not seen in 1 minute. The peak of the action occurs in 30 minutes, not the onset of action. The duration of action is 2 hours, not the onset of action. | ||
| 4. | A patient is administered furosemide (Lasix) 20 mg PO every morning. What effect will a diet high in sodium have on the patient? | |
| A) | Decreased blood pressure | |
| B) | Decreased diuresis | |
| C) | Hyperkalemia | |
| D) | Hyperglycemia | |
| Ans: | B | |
| Feedback: | ||
| A high dietary intake of sodium can cause sodium retention and reduce or cancel the diuretic-induced sodium loss. A high dietary intake of sodium will not increase diuresis. A high dietary intake of sodium will not cause hyperkalemia. A high dietary intake of sodium will not cause hyperglycemia. | ||
| 5. | A patient is switched from furosemide (Lasix) to spironolactone (Aldactone). The patient asks the nurse why she has been switched to a new medicine. What is the nurse’s best response? | |
| A) | “You will lose less potassium with spironolactone than with furosemide.” | |
| B) | “You will have greater potassium losses with spironolactone than with furosemide.” | |
| C) | “You will have greater water losses with spironolactone than with furosemide.” | |
| D) | “You will have greater sodium losses with spironolactone than with furosemide.” | |
| Ans: | A | |
| Feedback: | ||
| Spironolactone promotes retention of sodium and water and excretion of potassium by stimulating the sodium–potassium exchange mechanism in the distal tubule. The patient will not have greater potassium losses, water losses, or sodium losses with spironolactone rather than furosemide. | ||
