A nurse is reviewing ECG rhythm strips for a group of clients. The nurse should identify that which of the following rhythms indicates bradycardia?

A
B
C
D
The Correct Answer is C
Sinus bradycardia is a type of cardiac arrhythmia characterized by a heart rate lower than 60 beats per minute in adults, or below the normal range for age in children. It can be diagnosed by an electrocardiogram (ECG) that shows regular P waves with constant morphology preceding every QRS complex, and positive in lead II.

Correct Answer is C
Explanation
Referred pain is pain that is felt in a location different from its source due to shared nerve pathways or central nervous system processing. A client who has pancreatitis may experience pain in the left shoulder due to irritation of the diaphragm by pancreatic enzymes or inflammation. This pain is referred from the abdominal cavity to the shoulder through the phrenic nerve.
A client who has peritonitis reports generalized abdominal pain that corresponds to the site of inflammation and infection in the peritoneum. A client who has angina reports substernal chest pain that reflects the ischemia and hypoxia of the myocardium. A client who is postoperative reports incisional pain that is caused by tissue damage and inflammation at the surgical site.
Correct Answer is A
Explanation
Applying an ice pack to the client's knee can help reduce inflammation, swelling, and pain after a total knee arthroplasty. The nurse should avoid placing pillows under the client's knee, as this can cause flexion contractures and impair mobility and healing. Massaging or manipulating the incision site can increase pain and risk of infection or bleeding. Range-of-motion exercises are important for recovery, but they should be done with caution and under supervision, not when the client is experiencing severe pain.
