Cardiovascular System Questions Questions
Question 1 of 5
The nurse should administer amiodarone (Cordarone) to treat which of the following arrhythmias?
Correct Answer: C
Rationale: Amiodarone (C) treats life-threatening ventricular tachycardia by prolonging the action potential. Others (A, B, D) involve slower rates, not its primary use.
Question 2 of 5
Lymph from the lower half of the body drains into:
Correct Answer: C
Rationale: Lymph from the lower body drains into the thoracic duct via the cisterna chyli, which then empties into the left subclavian vein. The right lymphatic duct drains the upper right quadrant, and 'tracheal duct' is not a lymphatic structure.
Question 3 of 5
A client's parents ask the nurse, 'What is the prognosis of myocarditis?' The most appropriate response by the nurse is?
Correct Answer: B
Rationale: Myocarditis (heart muscle inflammation) often resolves spontaneously with rest and supportive care, especially if viral. Surgical options (A, C, D) are not typical primary treatments unless complications like severe heart failure arise.
Question 4 of 5
Examination of a patient in a supine position reveals distended jugular veins from the base of the neck to the angle of the jaw. This finding indicates:
Correct Answer: B
Rationale: Distended jugular veins in a supine position suggest increased central venous pressure (CVP), often due to right heart failure or fluid overload, as blood backs up into the venous system. Decreased venous return would collapse veins, and C and D are less directly indicated by this sign alone.
Question 5 of 5
A patient who is recovering from a myocardial infarction may benefit from meditation because this technique:
Correct Answer: A
Rationale: Meditation reduces sympathetic nervous system activity, lowering stress, heart rate, and oxygen demand, aiding MI recovery. B, C, and D increase cardiac workload, countering recovery goals.
