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.

A client with hemorrhoids asks for information about a high fiber diet. Which breakfast menu items should the nurse suggest? (Select all that apply.)
- A. Raisin bran muffins
- B. Bowl of oatmeal
- C. Cup of raspberries
- D. Scrambled eggs
Correct Answer: A
Rationale: A high-fiber diet is beneficial for managing hemorrhoids as it helps maintain bowel regularity. Raisin bran muffins are a good choice for breakfast as they are high in fiber. Oatmeal is also a high-fiber option that aids digestion and prevents constipation. Raspberries are rich in fiber and contribute to a high-fiber diet. Scrambled eggs, on the other hand, are not high in fiber and do not provide the necessary fiber content needed for managing hemorrhoids.
A client with a diagnosis of chronic obstructive pulmonary disease (COPD) is receiving home oxygen therapy. What is the most important instruction the nurse should provide?
- A. Use oxygen at the highest flow rate tolerated.
- B. Do not smoke while using oxygen.
- C. Avoid wearing the oxygen during physical activity.
- D. Store oxygen tanks in a cool, dark place.
Correct Answer: B
Rationale: The most important instruction the nurse should provide to a client with COPD receiving home oxygen therapy is not to smoke while using oxygen. Smoking near oxygen can cause a fire or explosion due to the flammable nature of oxygen. Choice A is incorrect because using oxygen at the highest flow rate tolerated without medical supervision can be harmful. Choice C is the correct answer as wearing oxygen during physical activity can increase the risk of oxygen combustion. Choice D is not the most important instruction; while storing oxygen tanks properly is essential, the immediate safety concern is the risk of fire due to smoking near oxygen.
Which client assessment falls within the scope of practice for the practical nurse?
- A. An agitated client with bilateral wrist restraints
- B. New admission of a client with deep vein thrombosis
- C. Return of a post-anesthesia client following a colon resection
- D. Transfer of a client with sepsis from a long-term care facility
Correct Answer: B
Rationale: The correct answer is B because assessing a new deep vein thrombosis (DVT) patient is within the scope of practical nursing. It involves monitoring and supporting the circulatory system health, which is a common responsibility for practical nurses. Choices A, C, and D involve scenarios that are typically beyond the initial assessment and care provided by practical nurses. An agitated client with bilateral wrist restraints may require immediate intervention by higher-level healthcare providers due to safety concerns and potential underlying issues. The return of a post-anesthesia client following a colon resection and the transfer of a client with sepsis involve more specialized care that goes beyond the typical responsibilities of a practical nurse, often requiring interventions from registered nurses or physicians.
The nurse is assessing a client who has just received a blood transfusion. The client reports chills and back pain. What is the nurse's priority action?
- A. Slow the rate of transfusion.
- B. Administer an antipyretic.
- C. Stop the transfusion immediately.
- D. Notify the healthcare provider.
Correct Answer: C
Rationale: The correct answer is C: Stop the transfusion immediately. Chills and back pain are indicative of a possible transfusion reaction, which is a critical situation. Stopping the transfusion is crucial to prevent further complications and ensure the client's safety. Slowing the rate of transfusion (Choice A) is not sufficient in this case as immediate action is required. Administering an antipyretic (Choice B) may help with fever but does not address the potential severe reaction. Notifying the healthcare provider (Choice D) can be done after stopping the transfusion, but the priority is to halt the infusion to prevent harm.
The client with hypertension is being taught about lifestyle changes. Which recommendation is most important to include?
- A. Increase sodium intake
- B. Engage in regular physical activity
- C. Consume a diet high in saturated fats
- D. Limit fluid intake
Correct Answer: B
Rationale: Engaging in regular physical activity is crucial for managing hypertension as it helps lower blood pressure. Regular exercise can improve heart health, increase circulation, and contribute to overall well-being, all of which are beneficial for individuals with hypertension. Choice A, increasing sodium intake, is incorrect as reducing sodium is recommended for hypertension to help lower blood pressure. Choice C, consuming a diet high in saturated fats, is incorrect as a diet high in saturated fats can negatively impact blood pressure and cardiovascular health. Choice D, limiting fluid intake, is incorrect as maintaining adequate hydration is important for overall health and not directly related to hypertension management.
