Question 1

What baseline assessments should nurses perform before cardiac catheterization?

Accepted Answer

Before cardiac catheterization, nurses must assess for allergies to contrast dye and perform a comprehensive baseline evaluation. This includes vital signs, pulse oximetry, heart and breath sounds, and neurovascular assessment of the extremities, noting distal pulses, skin color, temperature, and sensation. Baseline laboratory values such as cardiac biomarkers and creatinine should also be evaluated to establish comparison points for post-procedure monitoring.

Question 2

What patient instructions should be given before cardiac catheterization?

Accepted Answer

Patients should withhold fluids and food for six to eight hours before the procedure. Nurses should educate patients and caregivers about the procedure, explaining that it typically lasts less than two hours and involves local anesthesia at the insertion site. Patients should be informed they may experience palpitations when the catheter touches the endocardium, a flushed feeling during dye injection, and a sensation of needing to urinate, which usually subsides within a minute.

Question 3

What sensations might patients experience during cardiac catheterization?

Accepted Answer

During dye injection, patients may experience a flushed feeling and a possible pounding sensation in the heart when the catheter touches the endocardium. Patients may also feel occasional palpitations and a sensation of needing to urinate, which typically subsides within a minute. Sedatives are administered as prescribed to help manage patient comfort and anxiety during the procedure.

Question 4

How should nurses monitor the catheter insertion site after the procedure?

Accepted Answer

After cardiac catheterization, nurses must observe the insertion site for hematoma and bleeding and assess the extremity's neurovascular status every 15 minutes for the first hour and every 30 minutes for the next hour. Assessment includes checking peripheral pulses, skin color, temperature, capillary refill, and sensation. Nurses should monitor for signs of arterial insufficiency such as pain, numbness, or tingling and report any bleeding or complications immediately.

Question 5

What post-procedure cardiac monitoring is essential after catheterization?

Accepted Answer

Nurses must monitor the ECG for dysrhythmias and assess vital signs and heart and breath sounds compared to pre-procedure baseline values. Screen for arrhythmias by observing the cardiac monitor or assessing apical and peripheral pulses for changes in rate and rhythm. Be alert for vasovagal reactions, which can cause bradycardia, hypotension, and nausea, often triggered by a distended bladder or discomfort during catheter removal.

Question 6

What activity restrictions apply after cardiac catheterization?

Accepted Answer

Activity restrictions typically last two to six hours post-procedure, depending on the arterial approach, catheter size, medications, and hemostasis method used. For femoral artery approaches, patients should maintain bed rest for up to six hours with the affected leg straight and the head of the bed elevated no more than 30 degrees. Patients may turn side to side while keeping the affected extremity straight and should request assistance when getting out of bed for the first time.

Question 7

What complications should nurses monitor for after cardiac catheterization?

Accepted Answer

Nurses should monitor for contrast-induced nephropathy by checking serum creatinine levels and ensuring adequate IV hydration to increase urinary output. Watch for signs of hypotension, hypertension, pulmonary embolism, and respiratory difficulty. Instruct patients to report any bleeding, chest pain, or sudden discomfort at the insertion site and monitor for orthostatic hypotension symptoms such as dizziness or lightheadedness when ambulating.
