Extract:
Question 1 of 5
A nurse is assessing a client who has atrial fibrillation. Which of the following pulse characteristics should the nurse expect?
Correct Answer: C
Rationale: Atrial fibrillation is characterized by an irregularly irregular pulse due to disorganized electrical activity in the atria, leading to inconsistent ventricular contractions.
Question 2 of 5
A nurse is providing teaching to a client who has a family history of hypertension. The nurse should inform the client that his blood pressure of 124/85 mm Hg places him in which of the following categories?
Correct Answer: B

A nurse on a medical-surgical unit is caring for a client who reports pain in the jaw, back, and shoulder, shortness of breath, and nausea. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: Obtaining an EKG is crucial for diagnosing myocardial infarction by assessing electrical activity of the heart. It helps identify ischemia or infarction. Early detection of abnormalities ensures prompt treatment and reduces complications.
