Cardiovascular Med Surg Questions Questions
Question 1 of 5
Which of the following is true regarding fluid management in AKI?
Correct Answer: B
Rationale: More conservative fluid resuscitation is associated with lower mortality in AKI, as excessive fluids can worsen outcomes by causing fluid overload.
Question 2 of 5
Second-degree heart block type I (Wenckebach) is characterized by
Correct Answer: B
Rationale: Type I second-degree block is associated with progressively lengthening PR intervals until one P wave is not conducted and becomes a dropped beat. Second-degree block is not characterized by an absence of P waves. Type II second-degree block is associated with a consistent PR interval and dropped beats. The ECG of third-degree block shows regularly occurring P waves that are independent of the ventricular rhythm.
Question 3 of 5
Which of the following patients are MOST at risk for developing heart failure?
Correct Answer: D
Rationale: Patients at highest risk for heart failure include those with conditions directly affecting the heart, such as myocardial infarction (A), valvular issues like mitral stenosis (C), and uncontrolled hypertension (E). Asthma, hypoparathyroidism (B), and lung cancer (D) are less directly linked to heart failure.
Question 4 of 5
Which action should the nurse in the hypertension clinic take to obtain an accurate baseline blood pressure(BP) for a new patient?
Correct Answer: B
Rationale: The patient should be seated with the feet flat on the floor. The BP is obtained in both arms, and the results of the two arms are not averaged. The patient does not need to be in the supine position. The cuff should be deflated at 2 to 3 mm Hg per second.
Question 5 of 5
During exercise, increased muscle contraction helps return more blood to the heart. This would lead to
Correct Answer: A
Rationale: Increased venous return from muscle contraction boosts the volume of blood pumped per beat (stroke volume) via the Frank-Starling mechanism.
