A nurse is caring for a client who has heart failure and a potassium level of 2.4 mEq/L. The nurse should identify which of the following medications as contributing to this lab value?
Nitroglycerin
Metoprolol
Spironolactone
Furosemide
The Correct Answer is D
Choice A reason : Nitroglycerin is used to treat angina pectoris and does not typically cause a decrease in potassium levels¹.
Choice B reason : Metoprolol is a beta-blocker used to treat high blood pressure and heart failure but is not known to significantly affect potassium levels¹.
Choice C reason : Spironolactone is a potassium-sparing diuretic and would not contribute to low potassium levels; it is more likely to cause hyperkalemia¹.
Choice D reason : Furosemide is a loop diuretic that can lead to hypokalemia by increasing the excretion of potassium in the urine. It is known to contribute to low potassium levels and should be identified as the medication affecting this lab value¹².

Correct Answer is D
Explanation
Choice A reason : Delegating the NG tube placement to a more experienced nurse does not address the client's refusal of the procedure. The nurse must respect the client's autonomy and decision-making rights.
Choice B reason : While a referral to Social Services may be appropriate in some cases, it does not directly address the immediate concern of the client's refusal of the NG tube placement.
Choice C reason : Seeking consent from the client's spouse is not appropriate as the client is competent and has the right to refuse treatment. The client's autonomy must be respected.
Choice D reason : Documenting the client's wishes and notifying the physician is the correct action. The nurse must respect the client's right to refuse treatment and communicate this decision to the physician so that alternative management can be considered.
Correct Answer is ["A","B","C","E","F"]
Explanation
Choice A reason : Morphine sulfate is used intravenously in acute heart failure with pulmonary edema because it can reduce preload and afterload, thereby decreasing the work of the heart and improving breathing.
Choice B reason : Administering oxygen is crucial for a client with pulmonary edema to improve oxygenation and relieve symptoms of hypoxia.
Choice C reason : Transporting the client to the coronary care unit is appropriate for continuous monitoring and management of acute heart failure and pulmonary edema.
Choice D reason : While placing the client in a high Fowler's position is recommended to ease breathing, the low Fowler's side-lying position is not typically indicated for pulmonary edema. Therefore, this choice is incorrect.
Choice E reason : Inserting a Foley catheter can help monitor urine output, especially important when administering diuretics like furosemide, and manage fluid status.
Choice F reason : Administering furosemide (Lasix), a diuretic, helps to reduce fluid overload and relieve pulmonary congestion in clients with heart failure and pulmonary edema.
