The use of plants in conventional modern medicine is evidenced by the drug atropine, which is derived from which plant?
- A. Digitalis purpurea
- B. Cephaelis ipecacuanha
- C. Rauwolfia serpentina
- D. Atropa belladonna
Correct Answer: D
Rationale: The correct answer is D: Atropa belladonna. Atropine is derived from Atropa belladonna plant. Atropa belladonna contains alkaloids which are used in modern medicine for various purposes. Digitalis purpurea (A) is known for digitalis, Cephaelis ipecacuanha (B) for ipecacuanha, and Rauwolfia serpentina (C) for reserpine, not atropine. Therefore, D is the correct choice for this question.

A client is hypertensive, and the doctor prescribes weight reduction. The client is excited about beginning the diet, but on arriving home the spouse states, "You have always been fat, and I am not going to starve because you can't control yourself." The client becomes anxious and is unable to participate in the diet plan, resulting in a weight gain of 5 pounds in 2 weeks. Which theorist could best be referred to for guidance regarding interventions in this situation?
- A. Martha E. Rogers
- B. Hildegard E. Peplau
- C. Florence Nightingale
- D. Myra Estrin Levine
Correct Answer: B
Rationale: The correct answer is B: Hildegard E. Peplau. Peplau's nursing theory focuses on interpersonal relations, emphasizing the nurse-client relationship. In this situation, the client's anxiety and inability to participate in the diet plan are directly related to the negative interaction with the spouse. Peplau's theory suggests that the nurse can intervene by providing emotional support, facilitating communication, and helping the client manage anxiety. Rogers' theory focuses on the science of unitary human beings, which is not directly applicable here. Nightingale's theory emphasizes environmental factors, not interpersonal relationships. Levine's theory focuses on conservation principles, which are not directly relevant to addressing the client's anxiety and relational issues. Therefore, Peplau's theory best guides interventions in this situation.
The number of reported medical errors demonstrates a need for what priority intervention?
- A. Simulation experiences
- B. Performance competency exercises
- C. Comprehensive instructor-constructed examinations
- D. Detailed care planning exercises
Correct Answer: A
Rationale: The correct answer is A: Simulation experiences. This intervention allows healthcare professionals to practice real-life scenarios in a controlled environment, improving skills and decision-making. It helps identify and address potential errors before they occur, enhancing patient safety. Other choices lack the hands-on, practical approach of simulations and may not adequately prepare professionals for real-world situations. Simulation experiences are crucial for enhancing clinical competence and reducing medical errors.
A nurse is evaluating Levin's Theory of Conservation to determine if it can be applied to patients in the initial phases of chemotherapy treatment. During this phase of theory acceptance, the nurse wants to determine if all the concepts of energy, structural integrity, personal integrity, and social integrity are included in the care of cancer treatment. The nurse is applying which criteria of theory acceptance?
- A. Inclusiveness
- B. Consistency
- C. Accuracy
- D. Fruitfulness
Correct Answer: A
Rationale: The correct answer is A: Inclusiveness. In this scenario, the nurse is evaluating if Levin's Theory of Conservation includes all the concepts related to energy, structural integrity, personal integrity, and social integrity in the care of cancer treatment. Inclusiveness as a criterion of theory acceptance involves determining if a theory encompasses all relevant concepts and variables within a certain domain. By ensuring that all key components are addressed, the theory can be considered comprehensive and applicable to various situations.
Choice B: Consistency, refers to the internal logical coherence of a theory, which is not the focus of the nurse's evaluation in this case.
Choice C: Accuracy, pertains to the degree to which a theory accurately reflects reality, which is not directly related to the nurse's current evaluation.
Choice D: Fruitfulness, involves the ability of a theory to generate new research and insights, which is not the primary concern for the nurse's assessment of the theory's applicability to cancer treatment.
A novice nurse is unsure of his ability to insert a nasogastric tube for one of the assigned patients who is vomiting coffee ground emesis. The novice nurse waits, hoping that someone with more experience will volunteer to do the job, or he just waits until the end of the shift. This nurse is practicing:
- A. energy management.
- B. priority setting.
- C. procrastination.
- D. introspection.
Correct Answer: C
Rationale: The correct answer is C: procrastination. Procrastination is the act of delaying or avoiding a task that needs to be accomplished. In this scenario, the novice nurse is avoiding the task of inserting a nasogastric tube for a patient who needs it due to uncertainty and fear. Waiting for someone else to volunteer or delaying the task until the end of the shift are clear examples of procrastination. Energy management (A) involves efficiently allocating time and resources, which is not demonstrated here. Priority setting (B) would involve recognizing the urgency of the situation and taking appropriate action. Introspection (D) refers to self-reflection and analyzing one's thoughts and feelings, which is not the primary issue at hand in this scenario.
A new nurse asks, "Since Electronic Medical Records can improve quality care by having seamless data available for a patient, why doesn't everyone just replace paper and pencil charts"? Barriers to a universal health information infrastructure include the fact that: (select all that apply)
- A. competition from individual companies to build EMR prevent a universal infrastructure.
- B. cost is prohibitive even with federal funding for larger health care systems.
- C. preventive health reminders for immunizations and yearly screenings such as mammograms are used in clinical decision making.
- D. insurance companies have halted sharing of some patient data due to fear of law suits.
Correct Answer: A
Rationale: The correct answer is A because competition from individual companies to build EMR prevents a universal infrastructure. This is because different EMR systems may not be compatible with each other, hindering seamless data sharing.
Choice B is incorrect because while cost can be a barrier, federal funding can help mitigate this issue for larger healthcare systems. Choice C is incorrect because preventive health reminders are a benefit of EMR, not a barrier. Choice D is incorrect because insurance companies' fear of lawsuits does not directly impact the establishment of a universal health information infrastructure.
