A nurse is caring for a client who is taking furosemide (Lasix) daily to treat heart failure. The nurse recognizes that the client is at risk for which electrolyte imbalance?

Hypokalemia

Hypocalcemia

Hypernatremia

Hyperkalemia

Answer and Explanation

The Correct Answer is A

A. Hypokalemia: Furosemide is a loop diuretic that works by increasing urinary excretion of sodium, chloride, and water, which can lead to potassium loss. Hypokalemia is a common electrolyte imbalance associated with the use of loop diuretics like furosemide. Potassium depletion can cause various complications, including cardiac dysrhythmias, muscle weakness, and fatigue.

B. Hypocalcemia: Furosemide does not directly affect calcium levels, so hypocalcemia is not a common electrolyte imbalance associated with its use.

C. Hypernatremia: Furosemide promotes the excretion of sodium, so hypernatremia (elevated serum sodium levels) is not typically a concern with its use.

D. Hyperkalemia: Furosemide can cause potassium loss, so hyperkalemia is not a risk associated with its use.

Correct Answer is ["B","C","D","E"]

Explanation

A. Sterilize dishes before using: This is not typically necessary. Washing dishes with hot water and soap or using a dishwasher is sufficient to ensure they are clean.

B. Maintain good hygiene: Good hygiene practices are crucial for immunocompromised individuals to prevent infections.

C. Cook meats and fish well: Properly cooking meats and fish helps to kill any harmful bacteria and parasites that could cause infections.

D. Avoid consuming raw foods: Raw foods, especially meats, eggs, and some vegetables, can harbor harmful bacteria and parasites, posing a risk of infection.

E. Wash hands frequently: Frequent handwashing is one of the most effective ways to prevent the spread of infections.

A. Document how many inches the tube has been inserted. B. Auscultate both lungs for the presence of breath sounds. C. Secure the endotracheal tube to prevent dislodgement. D. Obtain a chest x-ray to ensure correct tube placement.

Correct Answer is B

Explanation

A. Document how many inches the tube has been inserted: While documentation of the tube insertion depth is important, it is not the highest priority immediately after intubation. Ensuring proper placement and ventilation take precedence.

B. Auscultate both lungs for the presence of breath sounds: This is the priority action to confirm that the endotracheal tube is correctly placed in the trachea and that both lungs are being ventilated adequately. Absence of breath sounds on one side could indicate mainstem intubation or displacement of the tube.

C. Secure the endotracheal tube to prevent dislodgement: Securing the tube is important, but it should be done after confirming proper placement and ventilation.

D. Obtain a chest x-ray to ensure correct tube placement: While a chest x-ray is often performed after intubation to confirm tube placement, it is not the immediate priority. Auscultation provides more immediate feedback on the effectiveness of ventilation.
