Question

The nurse evaluates that fluid resuscitation for a 70 kg patient in shock is effective on finding that the patient's ______.

a. urine output is 40 ml over the last hour.
b. hemoglobin is within normal limits.
c. CVP has decreased.
d. mean arterial pressure (MAP) is 65 mm Hg.

Answer 1

The nurse evaluates that fluid resuscitation for a 70 kg patient in shock is effective on finding that the patient's mean arterial pressure (MAP) is 65 mm Hg. (Option D). This implies sufficient perfusion of organs and an improved patient condition.

Step-by-step explanation:

When evaluating the effectiveness of fluid resuscitation in a 70 kg patient experiencing shock, healthcare providers look for several indicators that suggest the patient is responding well to treatment.

One key indicator is urine output, which provides information about kidney function and fluid balance within the body.

For an adult patient, urine output should be at least 0.5 to 1 mL/kg body weight/hour.

Therefore, for a 70 kg patient, a urine output of 40 ml over the last hour indicates inadequate renal function and suggests the need for ongoing resuscitation.

A key target in managing shock is maintaining an adequate mean arterial pressure (MAP), which is critical to ensure sufficient perfusion of organs. An acceptable MAP is usually considered to be at least 65 mm Hg, indicating better tissue perfusion.

Hence, the correct answer to the question would be: mean arterial pressure (MAP) is 65 mm Hg' as this suggests effective fluid resuscitation (Option D).
