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
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 C
Explanation
. Taking a hot shower in the morning can help decrease stiffness and improve joint mobility for people with rheumatoid arthritis. This is one of the self-management strategies that can reduce pain and disability.
Choice A is wrong because applying cold packs directly on the skin of the affected joints can cause vasoconstriction and increase inflammation.
Cold therapy should be used with caution and with a barrier between the skin and the ice pack.
Choice B is wrong because biological response modifiers are not used to prevent infection, but to reduce inflammation and slow down joint damage in rheumatoid arthritis.
These medications can actually increase the risk of infection by suppressing the immune system.
Choice D is wrong because clustering physical activities during the day can cause fatigue and joint stress for people with rheumatoid arthritis.
It is better to pace activities throughout the day and take frequent breaks to rest the joints.
Normal ranges for rheumatoid arthritis are based on the disease activity score (DAS), which measures the number of swollen and tender joints, the level of inflammation in the blood, and the patient’s global assessment of health. A DAS below 2.6 indicates remission, a DAS between 2.6 and 3.2 indicates low disease activity, a DAS between 3.2 and 5.1 indicates moderate disease activity, and a DAS above 5.1 indicates high disease activity.
Correct Answer is B,D,A,C
Explanation
B. Review the skill level and qualifications of each AP.
Before delegating tasks, the nurse should assess the skill level and qualifications of each AP to ensure they have the necessary knowledge and training to perform the assigned tasks safely and effectively.
D. Communicate appropriate tasks to the APs with specific expectations.
The nurse should clearly communicate the tasks to be delegated to each AP. This includes providing specific instructions, expectations, and any necessary information to ensure the APs understand what is expected of them and can perform the tasks correctly.
A. Monitor progress of task completion with each AP.
Once the tasks are assigned, the nurse should periodically check in with each AP to monitor the progress of task completion. This allows the nurse to provide support, answer questions, and ensure that tasks are being performed as expected.
C. Evaluate the APs' performance of each task.
After the tasks are completed, the nurse should evaluate the APs' performance of each task. This evaluation helps identify any areas for improvement, additional training needs, and overall competency of the APs.
Delegating tasks to assistive personnel is an essential aspect of nursing practice. Following this sequence of steps helps ensure that tasks are delegated appropriately and that the care provided is safe, efficient, and aligned with the APs' capabilities. Regular communication and feedback are essential to effective task delegation and teamwork within the healthcare setting.
