1. A practical nurse is reviewing the medication administration record for a client prescribed prednisone. What potential side effect should the nurse monitor for?
- A. Hypoglycemia
- B. Weight loss
- C. Hypertension
- D. Diarrhea
Correct answer: C
Rationale: Prednisone, a corticosteroid, can cause side effects such as hypertension, fluid retention, and weight gain. Hypertension is a common side effect of prednisone due to its impact on sodium and fluid retention in the body. Monitoring blood pressure is crucial to detect and manage hypertension in clients taking prednisone. Choices A, B, and D are incorrect. While prednisone can indirectly affect blood glucose levels, hypoglycemia is not a common side effect. Weight gain, not weight loss, is more prevalent with prednisone use. Diarrhea is not a typical side effect associated with prednisone.
2. A client is admitted to a long-term care facility, and the nurse and a new employee are conducting medication reconciliation. The nurse notes that oxybutynin has been prescribed. The nurse realizes the new employee understands the drug's effect if the new employee explains that this medication is prescribed to treat which condition?
- A. Pain
- B. Depression
- C. Overactive bladder
- D. Chronic anxiety
Correct answer: C
Rationale: The correct answer is C: Overactive bladder. Oxybutynin is prescribed to treat overactive bladder by reducing muscle spasms of the bladder. It is classified as an anticholinergic medication. Choices A, B, and D are incorrect. Oxycodone is an opioid used for pain management. Bupropion is an antidepressant used to treat depression. Buspirone is an anxiolytic used to manage anxiety disorders.
3. A client with osteoporosis is prescribed raloxifene. The nurse should reinforce which instruction?
- A. Take this medication at the same time each day.
- B. Take this medication with a full glass of water.
- C. Take this medication on an empty stomach.
- D. Take this medication immediately after a meal.
Correct answer: A
Rationale: The correct instruction for a client prescribed raloxifene, a medication used for osteoporosis, is to take it at the same time each day. This consistency helps maintain steady blood levels of the medication, enhancing its effectiveness in managing the condition. Choice B is incorrect because raloxifene does not require a full glass of water for administration. Choice C is incorrect as raloxifene should not be taken on an empty stomach. Choice D is incorrect as raloxifene should not be taken immediately after a meal.
4. A practical nurse (PN) is preparing to administer enoxaparin to a client. What is the most important action for the PN to take before administering this medication?
- A. Assess the client's blood pressure.
- B. Check the client's platelet count.
- C. Monitor the client's urine output.
- D. Review the client's blood glucose level.
Correct answer: B
Rationale: The correct answer is to check the client's platelet count. Enoxaparin can lead to thrombocytopenia (low platelet count), which can increase the risk of bleeding. Therefore, assessing the platelet count before administering enoxaparin is crucial to ensure that it is within a safe range. Assessing the client's blood pressure (Choice A) is not directly related to enoxaparin administration. Monitoring urine output (Choice C) and reviewing blood glucose levels (Choice D) are not essential actions before administering enoxaparin.
5. A client with a diagnosis of bipolar disorder is prescribed oxcarbazepine. The nurse should monitor for which potential adverse effect?
- A. Hyponatremia
- B. Agranulocytosis
- C. Liver toxicity
- D. Weight gain
Correct answer: A
Rationale: The correct answer is A, Hyponatremia. Oxcarbazepine, an anticonvulsant used in bipolar disorder, can lead to hyponatremia. This is because it can cause the body to retain water, leading to a dilution of sodium levels in the blood. Monitoring sodium levels is crucial to prevent complications such as confusion, seizures, and even coma. Choices B, C, and D are incorrect. Agranulocytosis is not typically associated with oxcarbazepine use. Liver toxicity is a potential adverse effect of some medications but not commonly seen with oxcarbazepine. While weight gain can be a side effect of certain medications used in bipolar disorder treatment, it is not a common adverse effect of oxcarbazepine.
