A patient is ordered 20 unit/kg IV bolus of Heparin. The patient weighs 154 lbs. Heparin is supplied 25,000 units/250 mL. How many mL will the nurse administer? (round to the nearest whole number)

Answer and Explanation

The Correct Answer is ["14"]

154 lbs ÷ 2.2 lbs/kg = 70 kg

20 units/kg * 70 kg = 1400 units

1400 units ÷ 25,000 units/250 mL = 14 mL

Therefore, the nurse will administer 14 mL of Heparin.

Correct Answer is B

Explanation

A. A negative output would imply that the client has produced less urine than the irrigation received, which is not the case here.
B. The true urine output is 675 mL, calculated by subtracting the irrigation amount from the total urine collected.
C. The calculation does not support this value, as it does not accurately reflect the total urine output after accounting for the irrigation.
D. Similar to option A, a negative value does not apply here since the urine output exceeds the irrigation amount.

A. Complaints of pain at the incision B. Increased blood pressure C. Decreased white blood cell count D. Presence of blood on the pillow behind the patient

Correct Answer is D

Explanation

A. While pain can occur post-operatively and may be a sign of complications, it is not a direct indicator of bleeding. Pain can result from normal healing, surgical trauma, or other complications, but by itself, it does not specifically point to bleeding at the surgical site.
B. An increased blood pressure might not necessarily indicate bleeding. In some cases, blood pressure may increase due to pain, anxiety, or other factors. However, a significant drop in blood pressure would be more indicative of bleeding, especially in conjunction with other symptoms.
C. A decreased white blood cell count (leukopenia) is not typically associated with bleeding at the surgical site. In fact, following surgery, one might expect the white blood cell count to be normal or slightly elevated due to the body’s response to surgery.
D. This finding is indicative of bleeding at the surgical site. Blood on the pillow would suggest that there is active bleeding that has escaped from the surgical site, which is a significant concern that requires immediate assessment and intervention.
