An adult client with third-degree AV block is admitted to the cardiac care unit and placed on continuous cardiac monitoring. What rhythm characteristic will the ECG most likely show?

History of type 2 diabetes

Interval and RR interval are irregular

Shortened PR interval

Inconsistently shaped P waves

PR interval is constant.

Apical heart rate

Fewer QRS complexes than P waves

PP interval is equal to RR interval.

Answer and Explanation

Correct Answer : G

A. History of type 2 diabetes is not a rhythm characteristic seen on an ECG. While diabetes can contribute to the development of cardiovascular issues, it does not specifically describe the characteristics of a third-degree AV block on an ECG.
B. Interval and RR interval are irregular is incorrect. In third-degree AV block (also known as complete heart block), the atrial rate and ventricular rate are typically regular, but the atrial and ventricular rhythms are completely dissociated.
C. Shortened PR interval is incorrect. In third-degree AV block, there is no consistent PR interval because the atria and ventricles are functioning independently.
D. Inconsistently shaped P waves is incorrect. P waves may appear normal, but the relationship between P waves and QRS complexes is lost in third-degree AV block.
E. PR interval is constant is incorrect. In third-degree AV block, the PR interval is inconsistent or absent, as the atrial and ventricular rates are independent of each other.
F. Apical heart rate is irrelevant here. The ECG will show the characteristic findings of third-degree AV block rather than focusing on apical heart rate alone.
G. Fewer QRS complexes than P waves is correct. In third-degree AV block, the atrial impulses (P waves) are conducted normally, but the ventricles are completely dissociated from the atrial rhythm, leading to fewer QRS complexes than P waves, as the ventricles may be paced by an escape rhythm.
H. PP interval is equal to RR interval is not necessarily true in third-degree AV block. The PP and RR intervals may be different depending on the escape rhythm, but they are not usually exactly equal.

Correct Answer is D

Explanation

A. A minor with acute pain is incorrect because while urgent, it does not pose an immediate life-threatening risk and would likely fall into the urgent category.
B. A postmenopausal woman with bruising is incorrect because bruising alone does not indicate an immediate life-threatening condition and would be categorized as non-urgent.
C. A sexually assaulted patient with multiple facial fractures is incorrect because while serious, it is not immediately life-threatening and would likely be categorized as urgent.
D. A rape victim with active hemorrhage in the abdomen is correct because uncontrolled bleeding is life-threatening and requires immediate intervention, placing this patient in the emergent category.

A. Overlooking the patient's need to talk about the incident B. Discontinuing any psychotropic medications C. Validating the patient's worth and self-esteem D. Limiting interaction with the patient due to antisocial behaviors exhibited by the suicide attempt

Correct Answer is C

Explanation

A. Overlooking the patient's need to talk is incorrect because ignoring their emotional distress may increase feelings of isolation and hopelessness.
B. Discontinuing psychotropic medications is incorrect as these medications may be essential in stabilizing mood and preventing further self-harm.
C. Validating the patient's worth and self-esteem is correct as it helps promote a sense of value, belonging, and hope, which are crucial in suicide prevention and recovery.
D. Limiting interaction with the patient is incorrect because social isolation can worsen depression and increase the risk of further self-harm.
