1. 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?
- A. To alter the pH level of the urine
- B. To reduce the frequency of bladder spasms
- C. To alleviate the painful symptoms caused by the UTI
- D. To prevent bacterial replication and resistance development
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.
2. A client with a history of stroke is prescribed clopidogrel. The nurse should monitor for which potential side effect?
- A. Bleeding
- B. Weight gain
- C. Nausea
- D. Headache
Correct answer: A
Rationale: When a client with a history of stroke is prescribed clopidogrel, the nurse should monitor for potential side effects, especially bleeding. Clopidogrel is an antiplatelet medication that works by preventing blood clots. One of the major risks associated with clopidogrel is an increased tendency to bleed. Therefore, monitoring for signs of bleeding, such as easy bruising, blood in stool or urine, or prolonged bleeding from minor cuts, is crucial to ensure patient safety and early intervention if needed.
3. What instruction should the nurse include in the teaching plan for a client prescribed etanercept for rheumatoid arthritis?
- A. Rotate injection sites to prevent irritation.
- B. Take this medication with food to reduce gastrointestinal upset.
- C. Avoid sunlight exposure while on this medication.
- D. Notify the healthcare provider of any signs of infection.
Correct answer: A
Rationale: The correct instruction for a client prescribed etanercept is to rotate injection sites to prevent irritation and ensure proper absorption. Changing sites will help prevent skin irritation and ensure that the medication is absorbed effectively. This practice also reduces the risk of injection site reactions and discomfort. It is essential to follow this instruction to promote optimal medication delivery and minimize adverse effects. Choice B is incorrect because etanercept can be taken with or without food, and it is not specifically indicated to be taken with food to reduce gastrointestinal upset. Choice C is incorrect as there is no specific association between etanercept and sunlight exposure. Choice D is incorrect because while it is important to notify the healthcare provider of signs of infection, this is not the primary instruction related to the administration of etanercept.
4. A client with a history of deep vein thrombosis is prescribed rivaroxaban. The nurse should monitor for which potential adverse effect?
- A. Increased risk of bleeding
- B. Decreased risk of bleeding
- C. Increased risk of infection
- D. Decreased risk of infection
Correct answer: A
Rationale: When a client with a history of deep vein thrombosis is prescribed rivaroxaban, the nurse should monitor for signs of bleeding as rivaroxaban increases the risk of bleeding. Common adverse effects of rivaroxaban include bleeding events, such as easy bruising, prolonged bleeding from cuts, or blood in the urine or stool. It is crucial for the nurse to assess for these signs to prevent complications and ensure the client's safety. Choices B, C, and D are incorrect because rivaroxaban does not decrease the risk of bleeding, increase the risk of infection, or decrease the risk of infection. Monitoring for bleeding is essential due to the anticoagulant properties of rivaroxaban.
5. A client with gastroesophageal reflux disease (GERD) is prescribed omeprazole. The nurse should reinforce which instruction?
- A. Take this medication in the morning before breakfast.
- B. Take this medication with meals.
- C. Avoid taking this medication with antacids.
- D. Take this medication at bedtime.
Correct answer: A
Rationale: The correct instruction for a client with GERD prescribed omeprazole is to take the medication in the morning before breakfast. Omeprazole works best when taken on an empty stomach, approximately 30 minutes before the first meal of the day. This timing maximizes its effectiveness in reducing stomach acid production and helps manage symptoms of GERD more efficiently. Choice B is incorrect because taking omeprazole with meals may reduce its efficacy as it needs an empty stomach for optimal absorption. Choice C is incorrect because omeprazole can be taken with or without food, but it should not be taken with antacids as they can affect its absorption. Choice D is incorrect because taking omeprazole at bedtime is less effective compared to taking it before breakfast due to the circadian rhythm of gastric acid secretion.
