Question 1 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.
Question 2 of 5
Six months after starting disulfiram for treatment of alcoholism, the client has serum laboratory tests completed (see exhibit). Place an X on each serum laboratory result that the nurse should report immediately to the HCP.
Correct Answer: B,C,DE,F
Rationale: Abnormal liver function tests (low albumin, elevated AST, ALT, total bilirubin, ALP) should be reported due to disulfiram's potential liver effects. [Image-based question; X on abnormal LFTs.]
Question 3 of 5
The nurse is storing vaccines for future use. What should the nurse do so they are properly stored? Select all that apply.
Correct Answer: B,D,E,F
Rationale: A: Not all vaccines are refrigerated; some vaccines will be inactivated by refrigeration and freezing. B: Periodic checking for expiration dates is necessary to ensure that outdated vaccines are not administered. C: Not all bulk supplies should be placed in a freezer; some vaccines are inactivated by freezing. D: When refrigeration is required, a main shelf inside the refrigerator is best because a shelf in the door will have frequent temperature changes that will alter the potency of the vaccine. E: Storing food and beverage in the same unit may result in frequent opening of the unit, leading to greater chance of temperature instability and light exposure. Contamination may also result. F: Aluminum foil or packaging can be used to protect light-sensitive vaccines.
Question 4 of 5
A client receiving drug therapy with furosemide and digitalis requires careful observation and care. In planning care for this client, the nurse should recognize that which of the following electrolyte imbalances is most likely to occur?
Correct Answer: C
Rationale: Furosemide, a diuretic, commonly causes potassium loss, leading to hypokalemia, which can potentiate digitalis toxicity, requiring close monitoring.
Question 5 of 5
Cyclosporine and methotrexate are prescribed for the client with severe rheumatoid arthritis. What information should the nurse address when teaching the client? Select all that apply.
Correct Answer: B,C,E
Rationale: A: Grapefruit juice should be avoided because it can increase the concentration of cyclosporine. B: Adequate hydration minimizes the risk of adverse effects. C: St. John's wort decreases cyclosporine levels. Echinacea and melatonin interact with cyclosporine to alter immunosuppression. D: Methotrexate and cyclosporine can be taken orally instead of by injection. It is incorrect that both medications are taken weekly. Only methotrexate is taken weekly, whereas cyclosporine is usually taken twice daily. E: Methotrexate and cyclosporine both have immunosuppressive effects.
