A nurse is performing discharge teaching with her patient and going over the information about her Furosemide (Lasix) (loop diuretic). One important teaching point for the nurse to remember is:

Be sure to take your potassium supplements

Report any excessive urinating to your physician

Take your Lasix at night before bed

Report any skin changes to your physician

Answer and Explanation

The Correct Answer is A

A. Be sure to take your potassium supplements: Furosemide is a loop diuretic that increases the excretion of sodium and water along with potassium. Hypokalemia is a common side effect, so potassium supplementation or increased dietary intake may be necessary to prevent complications such as muscle cramps or cardiac arrhythmias.

B. Report any excessive urinating to your physician: Increased urination is an expected therapeutic effect of Furosemide. It is only concerning if it leads to dehydration, dizziness, or signs of electrolyte imbalance.

C. Take your Lasix at night before bed: Taking Furosemide at night is not recommended due to its diuretic effect, which may cause nocturia and disrupt sleep. It is best taken in the morning or early afternoon.

D. Report any skin changes to your physician: Skin changes are not a common or critical concern specifically associated with Furosemide. Monitoring for electrolyte imbalances and dehydration is more important in routine patient education.

Correct Answer is D

Explanation

A. Low Blood Pressure and Dizziness: Low blood pressure and dizziness are more commonly associated with other conditions such as dehydration or blood loss. Hypocalcemia may cause symptoms like muscle cramps or tingling but not typically low blood pressure.

B. Edema to the extremities: Edema is often related to conditions such as heart failure, kidney disease, or inflammation, not directly to low calcium levels. Hypocalcemia does not typically present with edema in the extremities, so this is not a likely finding.

C. High temperature and sweating: High temperature and sweating are not characteristic of hypocalcemia. These symptoms are more often seen with fever, infection, or hyperthyroidism, not with low calcium levels, which usually cause neuromuscular symptoms.

D. Positive Chvostek's Sign and Anxiety: A calcium level of 7.8 mg/dL is low, and hypocalcemia can cause neuromuscular irritability, including a positive Chvostek's sign. Anxiety is also common in hypocalcemia due to its effect on the nervous system.

A. Pour out the top 10 mL of liquid and continue to utilize the bottle. B. Obtain a new bottle of sterile saline. C. Shake the bottle to ensure contents are mixed. D. Switch to a bottle of sterile water.

Correct Answer is B

Explanation

A. Pour out the top 10 mL of liquid and continue to utilize the bottle: Discarding a small portion of the solution does not ensure sterility after the bottle has been open for more than 24 hours. Continued use beyond the recommended time can increase the risk of contamination and infection.

B. Obtain a new bottle of sterile saline: Once a sterile saline bottle is opened, it is typically considered safe for use only within 24 hours. To maintain sterility and prevent infection, a new bottle should be used for the dressing change.

C. Shake the bottle to ensure contents are mixed: Shaking the bottle does not address sterility or contamination concerns. Sterile saline does not require mixing, and shaking it does not make it safe to use after the expiration of the safe usage window.

D. Switch to a bottle of sterile water: Sterile water is not an appropriate substitute for sterile saline in all clinical situations. The choice of solution should be based on wound care protocols, and switching without clinical justification is not appropriate.
