1. What is important information to provide to a young adult female client planning to become pregnant?
- A. Discontinue this medication one month before.
- B. Breastfeeding is not recommended while.
- C. Baseline liver function results must be obtained.
- D. Do not take multiple vitamins that contradict.
Correct answer: A
Rationale: It is crucial to advise the client to discontinue medication one month before planning to become pregnant to prevent potential harm to the fetus. This precaution is essential as certain medications can have adverse effects on the developing baby. By stopping the medication ahead of time, the client can reduce the risk of any complications during pregnancy.
2. A client with rheumatoid arthritis is prescribed methotrexate. What is the most important instruction the practical nurse (PN) should provide to the client?
- A. Take the medication on an empty stomach.
- B. Avoid taking folic acid supplements.
- C. Report any signs of infection immediately.
- D. Increase intake of vitamin C-rich foods.
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.
3. A client with type 2 diabetes mellitus is prescribed exenatide. The nurse should monitor for which potential adverse effect?
- A. Nausea
- B. Hypoglycemia
- C. Hyperglycemia
- D. Pancreatitis
Correct answer: A
Rationale: Exenatide, a medication commonly used in type 2 diabetes, is known to cause gastrointestinal side effects, such as nausea. Monitoring for nausea is essential as it can lead to decreased appetite and potential weight loss, affecting the nutritional status of the client. While hypoglycemia and hyperglycemia are important to monitor in diabetes management, they are not typically associated with exenatide use. Pancreatitis is a rare but serious adverse effect of exenatide, which requires immediate medical attention if suspected.
4. 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.
5. A client with a history of stroke is prescribed warfarin. The nurse should monitor for which potential side effect?
- A. Bleeding
- B. Weight gain
- C. Headache
- D. Dizziness
Correct answer: A
Rationale: The correct answer is A: Bleeding. Warfarin is an anticoagulant medication that works by thinning the blood. One of the potential side effects of warfarin is an increased risk of bleeding. It is crucial for the nurse to monitor the client for signs of bleeding, such as unusual bruising, blood in the urine or stool, or prolonged bleeding from cuts or gums. Prompt recognition and management of bleeding are essential to prevent complications. Choices B, C, and D are incorrect as weight gain, headache, and dizziness are not common side effects of warfarin. Monitoring for bleeding is a priority due to the anticoagulant properties of warfarin.
