A nurse is admitting a client who reports chest pain and has been placed on a telemetry monitor. Which of the following should the nurse analyze to determine whether the client is experiencing a myocardial infarction?
Twave
Ssegment
QRS duration
PR interval
The Correct Answer is B
The Ssegment is the portion of an electrocardiogram (ECG) that represents early ventricular repolarization, which occurs after ventricular contraction and before ventricular relaxation. The Ssegment can be elevated or depressed in cases of myocardial infarction (MI), indicating ischemia or injury to the myocardium due to reduced blood flow or oxygen supply.

Correct Answer is D
Explanation
A low potassium level (hypokalemia) can increase the risk for digoxin toxicity because it enhances the binding of digoxin to cardiac cells and increases its effects on cardiac contractility and electrical conduction. The nurse should monitor the client's potassium level and administer potassium supplements as prescribed if needed. The other electrolytes are not directly related to digoxin toxicity.
Correct Answer is D
Explanation
A flat lesion with irregular borders is one of the signs of melanoma, a type of skin cancer that arises from melanocytes, the cells that produce pigment. Other signs of melanoma include asymmetry, color variation, diameter greater than 6 mm, and evolution or change over time. The other options are more characteristic of other types of skin cancer or benign lesions.
