The nursing is caring for a patient who has had a left radial arterial line inserted 10 minutes ago. To reduce the risk of complications, what is the priority nursing intervention?

A. Have blood drawn weekly to check for high magnesium levels: Lisinopril, an ACE inhibitor, does not significantly affect magnesium levels. Regular monitoring is more important for potassium and renal function (BUN/creatinine), especially in heart failure patients, not magnesium.

B. Avoid the use of salt substitutes in your diet: Lisinopril is an ACE inhibitor. ACE inhibitors can cause potassium retention by reducing the production of aldosterone. Many salt substitutes contain high amounts of potassium chloride and combining the two may lead to hyperkalemia. Patients should be instructed to avoid these substitutes unless approved by their provider.

C. Notify your physician if a headache develops: Headache is a relatively common and usually mild side effect of lisinopril. It does not typically warrant discontinuation or immediate provider notification unless it's severe or persistent with other symptoms like dizziness or visual changes.

D. Take your heart rate daily when on this medication: Lisinopril does not significantly affect heart rate. Monitoring blood pressure is more relevant, as ACE inhibitors are antihypertensives. Heart rate monitoring is more critical with beta blockers or calcium channel blockers.

A. Assist the client from the stretcher to a wheelchair: Immediately after electroconvulsive therapy (ECT), the client is still recovering from anesthesia and may experience confusion, drowsiness, or muscle weakness. Transferring the client prematurely poses a fall risk and is not appropriate as the first action.

B. Orient the client and offer reassurance: While reorientation and reassurance are important aspects of post-ECT care, safety and physiological stability must be assessed first. This action should follow an initial assessment of vital signs and level of consciousness.

C. Encourage the client to drink some fluids: Offering fluids too soon after ECT is inappropriate because the client may have impaired swallowing reflexes from anesthesia or sedation. Ensuring the airway is clear and the client is fully alert must precede oral intake.

D. Assess vital signs and orient client to the PACU environment: The priority after any procedure involving anesthesia is to assess vital signs to ensure hemodynamic stability and monitor for complications. Once stable, the nurse can begin to orient the client, which is often needed after ECT due to temporary disorientation or memory lapses.
