What is the role of a nurse in a multidisciplinary team (MDT)?
- A. To lead the MDT
- B. To provide emotional support
- C. To advocate for patient needs
- D. To conduct clinical research
Correct Answer: C
Rationale: The correct answer is C - To advocate for patient needs. Nurses in an MDT play a crucial role in ensuring that the patient's best interests are prioritized and their needs are met. Nurses advocate for patients by communicating their preferences, coordinating care, and ensuring that all team members work together effectively. Leading the MDT (choice A) is typically done by the team leader, not specifically the nurse. Providing emotional support (choice B) is part of the nurse's role, but not the primary role in an MDT. Conducting clinical research (choice D) is important, but not the primary focus of a nurse in an MDT.

What is the main purpose of a healthcare proxy?
- A. To manage financial affairs
- B. To make medical decisions on behalf of the patient
- C. To provide legal representation
- D. To oversee patient discharge planning
Correct Answer: B
Rationale: The main purpose of a healthcare proxy is to make medical decisions on behalf of the patient when the patient is unable to do so. This includes decisions about treatment options, procedures, and end-of-life care. A healthcare proxy does not manage financial affairs (A), provide legal representation (C), or oversee patient discharge planning (D). These roles are typically carried out by different individuals or entities with specific responsibilities. The core function of a healthcare proxy is to ensure that the patient's medical wishes and best interests are upheld when they are unable to communicate or make decisions for themselves.
Which action by a patient indicates that the home health nurse’s teaching about glargine and
regular insulin has been successful?
- A. The patient administers the glargine 30 minutes before each meal
- B. The patient’s family prefills the syringes with the mix of insulins weekly.
- C. The patient draws up the regular insulin and then the glargine in the same syringe.
- D. The patient disposes of the open vials of glargine and regular insulin after 4 weeks
Correct Answer: D
Rationale: Step 1: Glargine and regular insulin should not be mixed in the same syringe as they have different onset and duration of action.
Step 2: Administering glargine 30 minutes before each meal is incorrect as it is a long-acting insulin.
Step 3: Pre-filling syringes weekly with the mix of insulins can lead to incorrect dosing or contamination.
Step 4: Disposing of open vials after 4 weeks is the correct action to ensure potency and safety of the insulin.
Summary: Choice D is correct because it demonstrates proper insulin storage and disposal practices. Choices A, B, and C are incorrect as they involve incorrect administration techniques or storage practices.
After the nurse has finished teaching a patient who has a new prescription for exenatide
(Byetta), which patient statement indicates that the teaching has been effective?
- A. “I may feel hungrier than usual when I take this medicine.”
- B. “I will not need to worry about hypoglycemia with the Byetta.”
- C. “I should take my daily aspirin at least an hour before the Byetta.”
- D. “I will take the pill at the same time I eat breakfast in the morning.”
Correct Answer: C
Rationale: The correct answer is C. This statement indicates effective teaching because taking aspirin at least an hour before exenatide (Byetta) helps prevent any potential interactions between the two medications. By understanding the importance of timing, the patient shows comprehension of medication management and potential risks.
Incorrect choices:
A: This choice is incorrect because exenatide is known to reduce appetite, not increase hunger.
B: This choice is incorrect because hypoglycemia is still a risk with exenatide, especially if used with other medications that lower blood sugar.
D: This choice is incorrect because exenatide is injected, not taken as a pill, and should be taken before meals, not with breakfast.
Which theory views motivation as learning?
- A. Reinforcement
- B. Process
- C. Operant
- D. Conditioning
Correct Answer: A
Rationale: The correct answer is A: Reinforcement. Reinforcement theory views motivation as learning through the use of positive or negative reinforcement to increase the likelihood of a behavior being repeated. By associating certain behaviors with rewards or punishments, individuals learn to be motivated to engage in those behaviors. The other choices, B: Process, C: Operant, and D: Conditioning, are incorrect because they do not specifically focus on motivation as a learned behavior through reinforcement. Process theory emphasizes cognitive processes, Operant theory focuses on shaping behavior through consequences, and Conditioning theory is a general term for learning through associations.
A nurse is caring for a client with a diagnosis of terminal cancer. Which of the following statements by the client should indicate to the nurse that the client is ready to hear information regarding palliative care?
- A. "I am ready to learn about chemotherapy to help cure my cancer."
- B. "I just want you to give me something to get this over with soon."
- C. "I want you to tell me about measures available to keep me comfortable."
- D. "I know that many people have recovered fully from cancer, and so will I."
Correct Answer: C
Rationale: The correct answer is C because the client's statement demonstrates a desire for comfort-focused care, which is the essence of palliative care for terminal cancer patients. The client is expressing a clear preference for measures that prioritize comfort and quality of life over aggressive treatment. This indicates readiness to receive information about palliative care.
Choice A is incorrect because the client mentions chemotherapy for a cure, indicating a focus on curative treatment rather than comfort care. Choice B is incorrect as the client seems to be expressing a desire for a quick end to their suffering, which may not align with palliative care goals. Choice D is incorrect because the client is expressing unrealistic optimism about recovery, which may hinder acceptance of palliative care.
