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.)
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. Turning the client every 4 hours is too infrequent for a postoperative patient. The client should be turned at least every 2 hours to prevent complications such as pressure injuries.
B. An air mattress may help prevent pressure ulcers, but it does not specifically address postoperative care for an amputation.
C. Using an overbed trapeze allows the client to move independently, reducing strain on the residual limb and promoting mobility while preventing pressure injuries.
D. The bandage should be rewrapped every 4 to 6 hours in a figure-eight pattern, not every 8 hours in a circular pattern, to promote proper shaping of the residual limb and prevent circulation issues.
Correct Answer is C
Explanation
A. Decaffeinated coffee is not recommended for clients with GERD because it can still increase gastric acid secretion, which may worsen symptoms.
B. Tomato soup is acidic and can trigger acid reflux, making it an unsuitable choice for clients with GERD.
C. White fish is a low-fat, non-acidic protein source that is unlikely to trigger GERD symptoms, making it an appropriate dietary choice.
D. Hot cocoa contains chocolate and caffeine, both of which can relax the lower esophageal sphincter (LES) and increase acid reflux.
