A nurse is caring for a client who is alert and oriented and is receiving continuous ECG monitoring.
The cardiac rhythm strip shows a wavy baseline, no distinguishable P waves, and an increased heart rate.
The nurse should identify the cardiac rhythm as which of the following?

Atrial fibrillation.

Ventricular asystole.

Second-degree heart block.

Sinus tachycardia.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

The described cardiac rhythm with a wavy baseline, no distinguishable P waves, and an increased heart rate is consistent with atrial fibrillation. In atrial fibrillation, the atria quiver instead of contracting effectively, leading to an irregular and often rapid heart rate. This rhythm is characterized by the absence of distinct P waves on the ECG.

Choice B rationale:

Ventricular asystole is a flatline on the ECG, indicating the absence of electrical activity in the heart. It is a life-threatening arrhythmia and requires immediate intervention with cardiopulmonary resuscitation (CPR) and advanced cardiac life support (ACLS) protocols.

Choice C rationale:

Second-degree heart block is characterized by intermittent failure of atrial electrical impulses to conduct to the ventricles. This results in occasional dropped beats and a varying heart rate. It is not consistent with the described ECG findings in the question.

Choice D rationale:

Sinus tachycardia is a regular, fast heart rate originating from the sinoatrial (SA) node. In sinus tachycardia, P waves are present, indicating that the electrical impulses originate in the SA node. The described ECG findings do not match the characteristics of sinus tachycardia.

Correct Answer is D

Explanation

Explanation: MRSA is a type of bacteria that is resistant to many antibiotics and can cause serious infections in various parts of the body. The nurse should wear a gown when assisting the client with personal hygiene to prevent contact transmission of MRSA to other clients or staff members. The nurse should also wear gloves and a mask and perform hand hygiene before and after contact with the client or their environment. The nurse should remove personal protective equipment before leaving the client's room and dispose of it properly to avoid contamination of other areas or surfaces. Negative air pressure is not required for MRSA isolation because it is not an airborne infection. The client's visitors should not be restricted, but they should be educated on the proper use of personal protective equipment and hand hygiene when visiting the client.

A. Amputation. B. Primary glaucoma. C. Hypertension. D. Osteoarthritis.

Correct Answer is C

Explanation

Choice A rationale:

Amputation, although a significant medical history, is not a contraindication to becoming a living kidney donor. The presence of an amputation does not directly impact the person's ability to donate a kidney to their parent.

Choice B rationale:

Primary glaucoma, a condition affecting the eyes, is also not a contraindication to kidney donation. While eye conditions can affect overall health, they do not specifically prevent an individual from donating a kidney if they are otherwise healthy.

Choice C rationale:

Hypertension (high blood pressure) is a contraindication to kidney donation. Individuals with hypertension are at a higher risk of developing kidney disease themselves. Additionally, donating a kidney could exacerbate their condition, potentially leading to further complications. Therefore, this is the correct choice.

Choice D rationale:

Osteoarthritis, a condition affecting the joints, is not a contraindication to kidney donation. Joint problems do not directly impact kidney function or the ability to donate a kidney.
