Answer and Explanation

The Correct Answer is ["0.4"]

To calculate the amount of heparin to administer, use the formula:

mL of heparin=units available units ordered×1mL available

Substituting the values given in the question, we get:

mL of heparin=100004000×11=0.4

Therefore, the nurse should administer 0.4 mL of heparin.

Normal ranges for heparin therapy vary depending on the condition being treated and the laboratory method used to measure APTT.

A general range is 60 to 80 seconds or 1.5 to 2.5 times the control value.

Correct Answer is D

Explanation

This site is preferred for peripheral IV catheter placement because it is comfortable, has good blood flow, and has a lower risk of complications than the dominant arm or the antecubital fossa.

Choice A is wrong because the dominant antecubital basilic vein is more prone to dislodgement, thrombosis, and thrombophlebitis due to frequent movement of the elbow joint.

Choice B is wrong because the nondominant dorsal venous arch is a distal site that may have poor blood flow and higher resistance to infusion. It should be avoided unless there are no other options.

Choice C is wrong because the dominant distal dorsal vein is also a distal site that may have poor blood flow and higher resistance to infusion. It should be avoided unless there are no other options.

A. Decrease in protein. B. Increase in BP. C. Oxygen saturation 96%. D. PaCO2, 30 mm Hg.

Correct Answer is B

Explanation

Albumin is a protein that helps maintain fluid balance in the body by drawing water into the blood vessels. Albumin infusion can increase the blood volume and blood pressure in patients who are in shock due to fluid loss or sepsis.

Choice A is wrong because albumin infusion does not decrease protein levels in the body.

Albumin is a protein itself and adding it to the blood increases the protein concentration.

Choice C is wrong because oxygen saturation of 96% is normal and does not indicate any improvement or deterioration in the patient’s condition.

Choice D is wrong because PaCO2 of 30 mm Hg is low and indicates respiratory alkalosis, which can be caused by hyperventilation, fever, or anxiety. Albumin infusion does not affect PaCO2 levels directly.
