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"]

ML

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 C

Explanation

A. Apply restraints if the client is agitated. Restraints are not necessary and may increase distress. Post-seizure agitation should be managed with reassurance and monitoring.
B. Ambulate the client. This is unsafe because the client may be disoriented or weak, increasing the risk of falls. Rest and recovery should be prioritized.
C. Position the client on their side. This helps maintain an open airway, prevents aspiration, and facilitates secretion drainage, making it the priority intervention.
D. Raise all of the side rails on the client's bed. Raising all four side rails is considered a restraint. A safer environment should be maintained without unnecessary restriction.

Correct Answer is D

Explanation

A. Iron supplementation does not have a significant interaction with spironolactone.
B. Magnesium is not contraindicated with spironolactone, though excessive intake should be monitored.
C. Calcium does not pose a major risk when taken with spironolactone.
D. Potassium should be avoided because spironolactone is a potassium-sparing diuretic, which can lead to hyperkalemia, a potentially life-threatening condition characterized by cardiac arrhythmias and muscle weakness.
