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?

Choice A reason : While it is true that a healthcare provider may come to explain the situation, this response does not directly address the parent's concern about the reason for the nurse's action. It is important for the nurse to communicate clearly and directly about their responsibilities and the actions they have taken.

Choice B reason : This response indicates that the nurse has taken action by reporting to a supervisor, but it does not clarify the nurse's legal obligation to report suspected child abuse. It is essential for nurses to understand and communicate their role as mandated reporters to ensure transparency and trust in the healthcare setting¹.

Choice C reason : This is the most appropriate response because it directly addresses the parent's question and explains the nurse's legal responsibility. Nurses are mandated reporters and are legally required to report any suspicions of child abuse to protect the child's welfare. This response is clear, direct, and upholds the nurse's professional and legal obligations¹³.

Choice D reason : While contacting a supervisor may be part of the protocol, this response does not provide the parent with an explanation for the nurse's action. It is important for the nurse to explain their legal duty to report suspected child abuse, which is the primary reason for their action.

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.
