A nurse is providing teaching about self-care to a primigravid client who is at 9 weeks of gestation. Which of the following statements should the nurse include?

A. Sensation of skin warmth. A warm or flushed sensation is common during cardiac catheterization, especially when contrast dye is injected. This is a normal and temporary response to the dye used in the procedure.
B. Increased salivation. Increased salivation is not a typical reaction during cardiac catheterization. It is not associated with the administration of contrast dye or catheter manipulation.
C. Numbness and tingling of the extremities. Numbness or tingling may indicate compromised circulation or nerve involvement, which is abnormal and should be reported immediately. It may suggest complications like arterial spasm or clot.
D. Headache. Headaches are not expected during a cardiac catheterization. If a headache occurs, especially a severe one, it should be evaluated further, as it could indicate a reaction or another complication.

A. Premature atrial complexes. These are early electrical impulses originating in the atria that cause premature heartbeats, but they do not consistently lengthen the P-R interval. The P-R interval usually remains within normal limits unless another condition is present.
B. First-degree atrioventricular (AV) block. A constant P-R interval longer than 0.20 seconds (normal range: 0.12–0.20 seconds) is characteristic of a first-degree AV block. A P-R interval of 0.35 seconds indicates a prolonged conduction delay through the AV node, consistent with this dysrhythmia.
C. Complete heart block. In complete (third-degree) heart block, there is no consistent relationship between P waves and QRS complexes, and the P-R interval is not constant. This is not consistent with a stable, prolonged P-R interval.
D. Atrial fibrillation. Atrial fibrillation is marked by irregularly irregular rhythm and absent, unidentifiable P waves, not a consistent P-R interval. The atria are quivering, not contracting in a coordinated way.
