Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A client with diabetes mellitus is prescribed insulin glargine. What information should the practical nurse (PN) provide to the client about this medication?
Correct Answer: B
Rationale: Insulin glargine is a long-acting insulin that should not be mixed with other insulins in the same syringe. Mixing it with other insulins can alter its pharmacokinetics and effectiveness. Insulin glargine is usually administered at the same time each day, often at bedtime, to provide a consistent basal level of insulin over 24 hours.
Question 3 of 5
A client with rheumatoid arthritis is prescribed methotrexate. What is the most important instruction the practical nurse (PN) should provide to the client?
Correct Answer: C
Rationale: Correct Answer: The most important instruction for a client taking methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the client more susceptible to infections. Early detection and treatment of infections are crucial to prevent complications. Instructing the client to be vigilant for signs of infection empowers them to take prompt action, enhancing their overall safety and well-being.
Question 4 of 5
A client is receiving heparin to treat a deep vein thrombosis. The nurse should monitor which laboratory result to assist in evaluating the efficacy of the drug?
Correct Answer: C
Rationale: The nurse should monitor the partial thromboplastin time to evaluate the efficacy of heparin. Partial thromboplastin time reflects the anticoagulant effect of heparin by measuring the intrinsic pathway of coagulation. Platelet count assesses platelet levels and is not specific to heparin efficacy. Prothrombin time is used to monitor warfarin therapy. Serum levels of protamine sulfate are not used to evaluate the efficacy of heparin.
Question 5 of 5
Phenazopyridine is commonly prescribed for clients with urinary tract infections (UTI). Which statement by the practical nurse describes the purpose for the administration of phenazopyridine?
Correct Answer: C
Rationale: The correct answer is C. Phenazopyridine, a urinary analgesic, is utilized to alleviate the pain associated with urinary tract infections (UTIs) like burning, pain, urgency, and frequent voiding. The administration of phenazopyridine can cause the urine to turn a bright red-orange color. It is recommended to take this medication with food to reduce gastric irritation. Phenazopyridine should only be used for a maximum of 2 days when taken alongside an antibacterial agent, which is typically prescribed for about 2 weeks to treat the underlying infection.
