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. Ask the child to complete homework in an area with minimal distractions. B. Have the child write assignments by hand instead of using a computer. C. Vary the child's scheduled activities each day. D. Encourage the child to read a book during an outdoor school activity period.

Correct Answer is A

Explanation

A. Minimizing distractions helps children with ADHD focus better and improves concentration.
B. Writing by hand does not necessarily enhance concentration and may actually increase frustration for some children with ADHD.
C. A structured and predictable routine is beneficial for children with ADHD, so varying activities daily may be counterproductive.
D. Encouraging a child to read during an outdoor activity period may limit needed physical movement, which can help manage ADHD symptoms.
