When teaching clients in a community-based setting strategies for preventing cardiovascular disease, which interventions should the nurse include?

Choice A rationale
The need for Metoprolol (Lopresor) STAT does not necessarily indicate progression to septic shock. Metoprolol is a beta-blocker used to treat high blood pressure, heart failure, and angina. While it may be used in the management of sepsis to control heart rate, its use does not specifically indicate progression to septic shock.
Choice B rationale
The need for Norepinephrine to maintain a mean arterial pressure (MAP) greater than 65 mmHg despite fluid replacement is a strong indicator of septic shock. Norepinephrine is a vasopressor, a type of medication used to increase blood pressure. In septic shock, vasopressors are often required to maintain adequate blood pressure and organ perfusion despite aggressive fluid resuscitation.
Choice C rationale
A serum lactate level less than 2 mmol/L is generally not indicative of septic shock. Elevated lactate levels can indicate tissue hypoperfusion, a condition that may occur in septic shock. However, a level less than 2 mmol/L is typically considered within the normal range.
Choice D rationale
A blood pressure of 70/34 after the fluid bolus could indicate progression to septic shock. In septic shock, despite aggressive fluid resuscitation, blood pressure often remains dangerously low, which can lead to inadequate blood flow to the organs.

Choice A rationale
Idiopathic vasospasm, or spontaneous constriction of the blood vessels, can cause myocardial ischemia. However, this is a relatively rare cause compared to atherosclerosis.
Choice B rationale
Atherosclerosis, a condition characterized by the buildup of fatty plaques in the arteries, is the most common cause of myocardial ischemia. These plaques can restrict blood flow to the heart muscle, leading to ischemia.
Choice C rationale
Venous emboli, or blood clots that form in the veins, typically do not cause myocardial ischemia. These clots are more likely to cause problems in the lungs (pulmonary embolism) if they travel through the bloodstream.
Choice D rationale
Arterial emboli from a heart valve can cause myocardial ischemia, but this is less common than atherosclerosis. These emboli, or blood clots, can block blood flow to the heart muscle if they travel through the bloodstream.
