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
The Correct Answer is C
- . Answer and explanation.
The correct answer is choice C, first-degree atrioventricular block.
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.

Explanation
This is a sign of preeclampsia, a serious complication of pregnancy that can cause high blood pressure, proteinuria, and seizures.

Preeclampsia can affect the placenta, the kidneys, the liver, and the brain of the mother and the fetus. It requires immediate medical attention and may lead to early delivery.
Choice A, bleeding gums, is wrong because it is a common occurrence during pregnancy due to hormonal changes that increase blood flow to the gums. It is not a cause for concern unless it is excessive or accompanied by other symptoms.
Choice B, urinary frequency, is wrong because it is also a normal finding during pregnancy due to the growing uterus putting pressure on the bladder. It is not a sign of infection or kidney problems unless it is associated with pain, burning, or blood in the urine.
Choice D, faintness upon rising, is wrong because it is usually caused by orthostatic hypotension, a drop in blood pressure when changing positions.
This can happen during pregnancy due to the dilation of blood vessels and the increased blood volume. It can be prevented by rising slowly, drinking enough fluids, and avoiding prolonged standing.
Correct Answer is A
Explanation
Encourage collaboration between the two nurses when making the assignments. This is because collaboration is one of the most effective conflict-resolution strategies in nursing, as it involves finding a mutually beneficial solution that satisfies both parties and improves the quality of care. Collaboration can also foster trust, respect, and teamwork among nurses, which can boost morale and efficiency.
Choice B is wrong because telling the nurses that the assignments will be more equitable in the future does not address the root cause of the conflict or involve the nurses in the decision-making process.
It also implies that the charge nurse admits to being unfair, which can damage their credibility and authority.
Choice C is wrong because asking each nurse to take turns making the assignments does not resolve the conflict, but rather avoids it. Avoidance is one of the least effective conflict management strategies in nursing, as it results in not addressing the issue or finding a common ground.
Avoidance can also lead to resentment, frustration, and poor communication among nurses.
Choice D is wrong because arranging for the nurses to have as few shifts together as possible also does not resolve the conflict, but rather accommodates it. Accommodation is another ineffective conflict management strategy in nursing, as it involves giving in to one party’s demands or preferences at the expense of another’s.
Accommodation can also create a sense of inequality, injustice, and dissatisfaction among nurses.
Normal ranges for conflict-resolution strategies in nursing are not applicable, as different situations may require different approaches.
However, some general guidelines are to use collaboration when both parties have important goals or interests, compromise when both parties have some common ground or willingness to give up something, competition when one party has a clear advantage or authority, avoidance when the conflict is trivial or temporary, and accommodation when one party values harmony or relationships more than their own goals or interests.
