A nurse is preparing to administer heparin at 1,000 units/hr via continuous IV infusion to a client who had a coronary artery bypass graft. Available is heparin 25,000 units in dextrose 5% in water in 250 mL. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["10"]

The formula to calculate the IV flow rate is:

mL/hr =

(Desired dose (units/hr)×Total volume (mL))/ Available dose

Substituting the given values:

(1,000×250)/25000

= 250,000/25,000

= 10ml/hr

Correct Answer is A

Explanation

A. Measure and record the client's leg circumferences daily. This is correct because measuring leg circumference helps assess for changes in swelling and monitor the progression or improvement of deep-vein thrombosis.
B. Place the client with their knees in a sharply flexed position. This is incorrect because sharply flexing the knees can impede blood flow and increase the risk of clot formation. The client should be encouraged to keep their legs extended and slightly elevated.
C. Monitor the client's RBCs every 4 hr. This is incorrect because deep-vein thrombosis does not typically require frequent RBC monitoring. Instead, coagulation studies such as PT, aPTT, and INR are more relevant.
D. Administer warfarin PO daily. This is incorrect because warfarin is contraindicated during pregnancy due to its teratogenic effects. Instead, low-molecular-weight heparin or unfractionated heparin is the preferred anticoagulant during pregnancy.

A. "Store unused patches in the refrigerator." B. "Apply the patchprior to traveling." C. "Place the patch on your upper arm." D. "Replace a dislodged patch onto the same location."

Correct Answer is B

Explanation

A. "Store unused patches in the refrigerator." Scopolamine patches should be stored at room temperature, not in the refrigerator.
B. "Apply the patch prior to traveling." The patch should be applied at least four hours before travel to allow time for absorption and effectiveness.
C. "Place the patch on your upper arm." The patch should be applied behind the ear, not on the upper arm, for optimal absorption.
D. "Replace a dislodged patch onto the same location." A new patch should be applied to a different area to prevent skin irritation.
