1. During a tonic-clonic seizure, what is the nurse's priority intervention?
- A. Insert an oral airway
- B. Administer oxygen via nasal cannula
- C. Restrain the client's arms and legs
- D. Protect the client's head from injury
Correct answer: D
Rationale: During a tonic-clonic seizure, the nurse's priority intervention is to protect the client's head from injury. This is crucial to prevent trauma, as head injuries can be severe during a seizure. Inserting an oral airway may cause injury or obstruction during the seizure and is not recommended. Administering oxygen via nasal cannula can be done after ensuring the client's safety. Restraining the client's arms and legs is also not recommended as it can lead to further injury or harm.
2. A client with a diagnosis of rheumatoid arthritis is prescribed methotrexate. What is the primary action of this medication?
- A. Increases joint lubrication
- B. Reduces inflammation by suppressing the immune system
- C. Enhances bone density
- D. Stimulates cartilage regeneration
Correct answer: B
Rationale: The correct answer is B: Methotrexate is an immunosuppressant that works by suppressing the immune system, thereby reducing inflammation in rheumatoid arthritis. Methotrexate does not directly increase joint lubrication (Choice A) as its primary action is on the immune system. Choices C and D are incorrect since methotrexate does not enhance bone density or stimulate cartilage regeneration. It is crucial for healthcare providers to understand the mechanism of action of medications to provide safe and effective care to patients.
3. The nurse is caring for a client with cirrhosis of the liver. Which clinical finding is most concerning?
- A. Jaundice.
- B. Ascites.
- C. Spider angiomas.
- D. Asterixis.
Correct answer: D
Rationale: The correct answer is D, Asterixis. Asterixis, also known as liver flap, is a sign of hepatic encephalopathy, a severe complication of liver disease that necessitates immediate attention. While jaundice (choice A), ascites (choice B), and spider angiomas (choice C) are common clinical findings in cirrhosis, asterixis is the most concerning due to its association with hepatic encephalopathy, which can lead to altered mental status and even coma. Jaundice, ascites, and spider angiomas are also important signs in cirrhosis, but asterixis indicates a more critical condition requiring urgent intervention.
4. A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?
- A. Stimulates insulin secretion from the pancreas.
- B. Increases insulin sensitivity in various tissues.
- C. Decreases hepatic glucose production.
- D. Delays absorption of glucose from the intestines.
Correct answer: C
Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.
5. A client with a history of atrial fibrillation is prescribed warfarin. Which lab value should the nurse monitor to assess the effectiveness of this medication?
- A. Hemoglobin
- B. White blood cell count
- C. Platelet count
- D. INR
Correct answer: D
Rationale: The correct answer is D, INR (International Normalized Ratio). The INR is used to monitor the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication commonly prescribed for conditions like atrial fibrillation. Monitoring the INR helps healthcare providers ensure that the blood is clotting within a therapeutic range. Hemoglobin (Choice A), white blood cell count (Choice B), and platelet count (Choice C) are not directly related to monitoring the effectiveness of warfarin therapy in this context.
