A nurse is reviewing a client’s cardiac rhythm strips and notes a constant P-R interval of 0.35 seconds.
Which of the following dysrhythmias is the client displaying?

Atrial fibrillation.

Complete heart block.

First-degree atrioventricular block.

Premature atrial complexes.

Answer and Explanation

The Correct Answer is C

This is because the PR interval is longer than normal, which indicates a delay in the conduction of electrical impulses from the atria to the ventricles through the AV node. A normal PR interval is 0.12 to 0.2 seconds, or 3 to 5 small squares on the EKG strip. In this case, the PR interval is 0.35 seconds, which is more than 5 small squares.

Choice A is wrong because atrial fibrillation is a type of arrhythmia where the atria beat irregularly and rapidly, producing chaotic and variable P waves and an irregular ventricular response.

There is no constant PR interval in atrial fibrillation.

Choice B is wrong because complete heart block is a type of arrhythmia where there is no conduction of electrical impulses from the atria to the ventricles, resulting in independent and dissociated atrial and ventricular rhythms.

There are no consistent P waves or PR intervals in complete heart block.

Choice D is wrong because premature atrial complexes are extra beats that originate from the atria and interrupt the normal sinus rhythm.

They produce abnormal P waves that are different from the sinus P waves, and may have a shorter or longer PR interval depending on the timing of the impulse.

However, they do not cause a constant prolongation of the PR interval.

Correct Answer is A

Explanation

Beneficence is the ethical principle of doing good for the patient and promoting their well-being.
The nurse is demonstrating beneficence by sitting with the client to provide comfort and support during a difficult time.
Choice B is wrong because fidelity is the ethical principle of keeping promises to the patient and being loyal and faithful.
The nurse is not making or keeping any promises to the client in this scenario.
Choice C is wrong because autonomy is the ethical principle of respecting the patient’s right to make their own decisions and choices.
The nurse is not interfering with the client’s autonomy in this scenario.
Choice D is wrong because veracity is the ethical principle of telling the truth to the patient and being honest and trustworthy.
The nurse is not lying or withholding information from the client in this scenario.

A. A client who is receiving heparin for deep-vein thrombosis. B. A client who is 1 day postoperative following vertebroplasty. C. A client who has cancer and a sealed implant for radiation therapy. D. A client who has COPD and a respiratory rate of 44/min.

Correct Answer is B

Explanation

A vertebroplasty is a procedure that injects cement into a fractured vertebra to help relieve pain and stabilize the spine. The recovery time for this procedure is usually short and the complications are rare.
Therefore, this client is most likely to be stable and ready for early discharge.
Choice A is wrong because a client who is receiving heparin for deep-vein thrombosis (DVT) needs close monitoring of their blood levels and clotting factors. Heparin is a blood thinner that prevents the clots from getting bigger or breaking loose and traveling to the lungs, which can cause a life-threatening condition called pulmonary embolism (PE).
This client is not a good candidate for early discharge.
Choice C is wrong because a client who has cancer and a sealed implant for radiation therapy needs to be isolated in a special room to prevent exposure of others to radiation. A sealed implant is a smallholder that contains a radioactive source that is placed inside or near the tumor to deliver high doses of radiation. This type of internal radiation therapy, also called brachytherapy, can last from several minutes to several days, depending on the type and dose of the radioactive source.
This client is not a good candidate for early discharge.
Choice D is wrong because a client who has COPD and a respiratory rate of 44/min has signs of respiratory distress and possible hypoxemia (low oxygen levels in the blood).
