Afterload is most accurately described by which of the following?

Fluid volume status.

Atrial contraction (kick).

Resistance to blood ﬂow.

Myocardial compliance.

Answer and Explanation

The Correct Answer is C

Choice A reason: Fluid volume status aﬀects preload, not afterload.
Choice B reason: Atrial contraction contributes to filling of the ventricles, not to afterload.
Choice C reason: Afterload is the resistance left ventricular must overcome to circulate blood, which is accurately described as resistance to blood ﬂow.
Choice D reason: Myocardial compliance refers to the elasticity of the heart muscle, which aﬀects how the heart fills, not the resistance it must overcome to eject blood.

Correct Answer is C

Explanation

Choice A reason : While maintaining a stable ECG rhythm is important, it is not the highest priority. The primary concern is to address life-threatening complications.

Choice B reason : Educating the patient about the causes and eﬀects of coronary heart disease (CHD) or coronary artery disease (CAD) is important for long-term management but is not the immediate priority during acute care.

Choice C reason : Adequate relief of pain is the highest priority in the care of a patient with AMI. Pain is an indicator of ongoing ischemia and can increase the workload of the heart, thereby worsening the condition.

Choice D reason (AMI): While bedrest is part of the care plan, it is not the highest priority compared to pain relief, which has direct implications on the patient's immediate physiological status.

A. Enhance the formation of granulation tissue. B. Ensure brisk bleeding from the sites so ﬂuid volume status can be maintained. C. Ensure the return of distal pulses. D. Decrease edema formation.

Correct Answer is C

Explanation

Choice A reason: Enhancing the formation of granulation tissue is not the immediate expected outcome of an escharotomy.

Choice B reason: Ensuring brisk bleeding is not the goal; minimal bleeding is expected, and it should be controlled to maintain ﬂuid volume status.

Choice C reason: Ensuring the return of distal pulses is the expected outcome of an escharotomy, as it relieves pressure and restores circulation to the aﬀected limbs.

Choice D reason: Decreasing edema formation is a benefit of the procedure but not the primary expected outcome.
