A nurse is providing preoperative teaching for a client who is having a left-sided cardiac catheterization.
Which of the following information should the nurse include in the teaching?
"You will receive a general anesthetic during the procedure.".
"You should plan to remain in bed for 18 hours after the procedure.".
"You should expect a warm sensation after the injection of the contrast dye during the procedure.".
"You will have blood pressure measurements every 5 minutes for the first 2 hours after the procedure.".
The Correct Answer is C
“You should expect a warm sensation after the injection of the contrast dye during the procedure.” During cardiac catheterization, a contrast dye is injected into the body to highlight blood flow through the arteries and show blockages in the blood vessels that lead to the heart.
This can cause a warm sensation.
Choice A is incorrect because usually, patients are awake during cardiac catheterization but are given medications to help them relax.
Choice B is incorrect because recovery time for a cardiac catheterization is quick.
Choice D is incorrect because there is no information found to support this statement.

Explanation
When administering packed RBCs, the tubing should be primed with 0.9% sodium chloride.
Transfusing each unit of blood over 5 hours (choice A) is not recommended as it may increase the risk of bacterial growth.
Packed RBCs should be transfused over 2 to 3 hours.
Changing the IV tubing after each unit of blood is transfused (choice B) is not necessary.
Administering the blood through a 22-gauge intravenous catheter (choice D) may not be appropriate as a larger gauge catheter is typically used for blood transfusions.

Explanation
A pacemaker sends electrical signals to the heart to regulate the heartbeat.
On an electrocardiogram (ECG), these signals appear as small spikes followed by a QRS complex, which represents the contraction of the ventricles.
Choice A, A regular sinus rhythm, is not the correct answer because a regular sinus rhythm is a normal heart rhythm that originates from the sinoatrial (SA) node and does not involve a pacemaker.
Choice B, A chaotic, irregular rhythm, is not the correct answer because a pacemaker is designed to regulate the heartbeat and prevent chaotic or irregular rhythms.
Choice C, the Absence of any electrical activity, is not the correct answer because a pacemaker sends electrical signals to the heart to regulate its activity.
