Answer;
- P-R interval
Explanation;
-P-R interval is the period of time from the onset of the P wave to the beginning of the QRS complex . This period normally ranges from 0.12 to 0.20 seconds in duration.
-The P-R interval represents the time between the onset of atrial depolarization and the onset of ventricular depolarization. A prolonged PR interval indicates delayed conduction of the sino-atrial, or SA, nodal impulse to the ventricles and is called first-degree AV block. A short PR interval can be seen when the AV node delay is bypassed.
Difficulty in breathing is the clinical manifestation that should alert the nurse to the fact that the client may be developing a life-threatening response to the drug atenolol.
At greater doses, Atenolol may function more similarly to non-selective beta-blockers, which means that it will affect both your heart and lungs. A potential drug interaction is a further worry. The beta receptors in your lungs and airways are really activated by some drugs.
It might be harder for your medication to operate well, particularly in an emergency, if your atenolol dose is high enough to block these airway receptors. These are the most severe side effects of atenolol, and they include bradycardia, cardiac failure, and pulmonary edoema. It might be wise to discuss this with your pulmonologist.
The complete question is : An older adult client who has type 1 diabetes and chronic bronchitis is prescribed atenolol for the management of angina pectoris. Which clinical manifestation should alert the nurse to the fact that the client may be developing a life-threatening response to the drug?
