Question 1 of 5
The HCP prescribes 1200 mL of TPN solution to be administered over 24 hours for the homebound client. The home health nurse should instruct the client to set the infusion pump to deliver how many mL per hour?
Correct Answer: 50
Rationale:
To calculate the infusion rate, divide the total volume by the total time: 1200 mL/ 24 hours = 50 mL per hour. The nurse should instruct the client to set the infusion pump to deliver 50 mL per hour.
Question 2 of 5
Which of these medications has the least risk of causing tinnitus?
Correct Answer: D
Rationale: Gentamicin, Lasix, and Aspirin are all ototoxic drugs that have a potential side effect of causing tinnitus, a ringing in the ear. Fluoxetine, an SSRI, is not typically associated with tinnitus.
Question 3 of 5
The nurse is teaching the client newly started on propranolol for acute situational anxiety disorder. In addition to treating the client's anxiety, the nurse should inform the client that propranolol's use is effective in treating which associated problem?
Correct Answer: B
Rationale: Propranolol (Inderal), a beta blocker, has been shown to be effective in ameliorating the somatic symptoms of anxiety such as hand tremor.
Question 4 of 5
A serious complication of a total hip replacement is displacement of the prosthesis. What is the primary sign of displacement?
Correct Answer: A
Rationale: Pain on movement and weight bearing indicates pressure on the nerves or muscles caused by the dislocation. Other symptoms of dislocation include an inability to bear weight and a shortening of the affected leg. Edema is not a primary sign of displacement.
Question 5 of 5
The unresponsive client with DM is admitted to the ED with a serum glucose level of 35 mg/dL. Which medication should the nurse plan to administer?
Correct Answer: D
Rationale: A: Exenatide (Byetta), a synthetic incretin mimetic, is used as an adjunct in type 2 diabetes to decrease blood glucose levels. B: Pramlintide (Symlin) lowers postprandial glucose levels by slowing gastric emptying. C: Miglitol (Glyset), an alpha-glucosidase inhibitor, lowers postprandial serum glucose levels. D: The nurse should plan to administer glucagon (GlucaGen). Glucagon, administered intramuscularly, intravenously, or subcutaneously, is used in unconscious clients with diabetes to reverse severe hypoglycemia from insulin overdose. Normal serum glucose is 70 to 110 mg/dL.
