A client with heart failure is prescribed digoxin. Which of the following assessment findings would require immediate nursing intervention?

A) Correct. Digoxin is a cardiac glycoside, and hypokalemia increases the risk of digoxin toxicity. A serum potassium level of 3.2 mEq/L indicates hypokalemia and requires immediate nursing intervention. Hypokalemia can potentiate the effects of digoxin on cardiac conduction, leading to dysrhythmias.

B) Incorrect. A heart rate of 60 beats per minute is within the expected range for a client taking digoxin, as it is commonly used to control heart rate in certain cardiac conditions.

C) Incorrect. A systolic blood pressure of 100 mmHg may be within an acceptable range for a client with heart failure, depending on their baseline blood pressure and symptoms. It does not require immediate nursing intervention.

D) Incorrect. A digoxin level of 1.2 ng/mL is within the therapeutic range for digoxin. It does not require immediate nursing intervention.

A) Correct. Nitroglycerin is a vasodilator primarily used to reduce angina and improve cardiac blood flow. Monitoring the client's blood pressure is crucial to assess the medication's effectiveness and prevent hypotension, a potential adverse effect. Nitroglycerin can cause significant vasodilation, leading to a drop in blood pressure, and the nurse should closely monitor the client's blood pressure during therapy.

B) Incorrect. Although monitoring respiratory rate is important, it is not the priority assessment when caring for a client receiving intravenous nitroglycerin.

C) Incorrect. Oxygen saturation should be monitored for clients receiving nitroglycerin, but it is not the priority assessment in this scenario.

D) Incorrect. Blood glucose levels are not directly affected by nitroglycerin and do not require prioritization in this case.
