Answer and Explanation

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 A

Explanation

A platelet count of 95,000/mm is below the normal range of 150,000 to 400,000/mm and indicates thrombocytopenia, which increases the risk of bleeding during surgery. The nurse should report this value to the surgeon and anticipate interventions such as transfusion of platelets or postponement of surgery. The other values are within normal limits and do not require immediate attention.

A. Maintain the affected extremity in a dependent position. B. Palpate the dorsalis pedis pulse. C. Wrap sterile gauze on the sharp point of the pins. D. Adjust the clamps on the fixator frame.

Correct Answer is B

Explanation

Palpating the dorsalis pedis pulse is an essential action to monitor for adequate circulation and perfusion in an extremity with an external fixator, which is a device that stabilizes and aligns fractured bones with metal pins and rods outside of the skin. The other options are incorrect because they could cause complications such as edema, infection, or malalignment.
