Question 1
Combined chemotherapy of tuberculosis is used to:
A. Decrease mycobacterium drug-resistance
B. Increase mycobacterium drug-resistance
C. Decrease the antimicrobal activity
D. Decrease the onset of antimycobacterial drugs biotransformation
Show answer and rationale
Correct answer: A — Decrease mycobacterium drug-resistance
The correct answer is A: Decrease mycobacterium drug-resistance. Combined chemotherapy of tuberculosis involves using multiple drugs to target different stages of the bacteria's life cycle, reducing the chances of resistance developing. This approach is effective in preventing the bacteria from adapting and becoming resistant to any single drug.
Explanation:
1. Using multiple drugs targets different mechanisms of action, making it harder for the bacteria to develop resistance.
2. Combination therapy can also prevent the growth of drug-resistant strains by attacking the bacteria from multiple angles.
3. By reducing the likelihood of resistance, combined chemotherapy increases the effectiveness of treatment and improves patient outcomes.
Summary:
B: Increase mycobacterium drug-resistance - This is incorrect as combined chemotherapy aims to decrease, not increase, drug resistance.
C: Decrease the antimicrobial activity - This is incorrect as combined chemotherapy actually enhances the antimicrobial activity against the tuberculosis bacteria.
D: Decrease the onset of antimycobacterial drugs biotransformation - This is
Question 2
A patient tells a nurse, “My doctor thinks my problem may lie with the neurotransmitters in my brain. What are neurotransmitters?†The reply that will give the patient the best understanding of neurotransmitters is, “Neurotransmitters are:
A. the chemical messengers that cause brain cells to turn on or off.â€
B. small clumps of cells that alert the other brain cells to receive messages.â€
C. tiny areas of the brain that are responsible for controlling our emotions.â€
D. weblike structures that provide connections among various parts of the brain.â€
Show answer and rationale
Correct answer: A — the chemical messengers that cause brain cells to turn on or off.â€
The correct answer is A: "the chemical messengers that cause brain cells to turn on or off." This is the best answer because neurotransmitters are indeed chemical substances that transmit signals across synapses between neurons, either exciting or inhibiting the receiving neuron. This explanation accurately describes the essential function of neurotransmitters in regulating brain cell activity.
Explanation for why the other choices are incorrect:
B: "small clumps of cells that alert the other brain cells to receive messages." This is incorrect as neurotransmitters are not clumps of cells but rather individual molecules that facilitate communication between neurons.
C: "tiny areas of the brain that are responsible for controlling our emotions." This is incorrect as neurotransmitters are not specific areas of the brain but rather chemicals that play a role in various brain functions, including emotions.
D: "weblike structures that provide connections among various parts of the brain." This is incorrect as neurotransmitters are not physical structures but chemical substances that facilitate communication between neurons.

Question 5
Family members have a need for information. Which intervention best assists in meeting this need?
A. Handing family members a pamphlet that explains all of the critical care equipment
B. Providing a daily update of the patient’s progress and f acilitating communication with the intensivist
C. Telling them that you are not permitted to give them a status report but that they can be present at 4:00 PM for family rounds with the intensivist
D. Writing down a list of all new medications and doses a nd giving the list to family members during visitation
Show answer and rationale
Correct answer: B — Providing a daily update of the patient’s progress and f acilitating communication with the intensivist
The correct answer is B because providing a daily update of the patient's progress and facilitating communication with the intensivist directly addresses the family members' need for information in a timely and personalized manner. This intervention ensures that the family is kept informed about the patient's condition and treatment plan, fostering transparency and trust. It also allows for any questions or concerns to be addressed promptly, aiding in the family's understanding and involvement in the patient's care.
Now, let's summarize why the other choices are incorrect:
A: Handing out a pamphlet may provide information, but it lacks the personalized touch and real-time updates that are crucial for meeting the family's need for information.
C: Restricting information and only allowing family members to be present at specific times may create frustration and hinder communication, not effectively meeting their information needs.
D: Providing a list of medications is helpful, but it does not offer a comprehensive update on the patient's progress or facilitate direct communication with the medical team, which are

Question 6
The physician prescribes haloperidol (Haldol), a first-generation antipsychotic drug, for a patient with schizophrenia who displays delusions, hallucinations, apathy, and social isolation. Which symptoms should most be monitored to evaluate the expected improvement from this medication?
A. Talking to himself, belief that others will harm him
B. Flat affect, avoidance of social activities, poor hygiene
C. Loss of interest in recreational activities, alogia
D. Impaired eye contact, needs help to complete tasks
Correct answer:
The correct answer is A because the symptoms of delusions and hallucinations are classic indicators of psychosis in schizophrenia. Monitoring improvements in these symptoms is crucial to evaluating the effectiveness of the antipsychotic medication. Delusions involve false beliefs, such as the patient talking to himself or believing others will harm him, while hallucinations involve sensory perceptions that are not real. Therefore, monitoring these symptoms will help assess the medication's impact on reducing the patient's psychotic symptoms.
Incorrect choices:
B: Flat affect, avoidance of social activities, poor hygiene - These symptoms are more indicative of negative symptoms of schizophrenia, which may not improve as rapidly or significantly with antipsychotic medication.
C: Loss of interest in recreational activities, alogia - These symptoms are also negative symptoms and may not directly reflect the improvement in psychotic symptoms targeted by haloperidol.
D: Impaired eye contact, needs help to complete tasks - These symptoms are not specific to delusions or hallucinations, which are the primary

A leukemia investigator plans to obtain bone marrow under general anesthesia to measure minimal residual disease (MRD) and to see if this time point can predict early relapse. The specimen will be obtained at a time point when otherwise no bone marrow would be sampled. The results are not shared with the treating oncologist, and no therapeutic interventions are decided or based on the results. Which of the following statements is most accurate about this intervention?
A. It constitutes a minimal-risk procedure because bone marrow assessments are considered routine for patients diagnosed with acute lymphoblastic leukemia.
B. It constitutes a minimal-risk procedure because it is a single additional procedure being performed during the course of treatment.
C. It constitutes a greater than minimal-risk procedure because it is being done under general anesthesia.
D. It is justifiable because future patients may benefit from knowledge gained by the research.
Correct answer:
The correct answer is C because obtaining bone marrow under general anesthesia carries inherent risks that make it greater than minimal-risk. Here's a step-by-step rationale:
1. General anesthesia poses risks such as allergic reactions, breathing problems, and potential complications, making the procedure more than minimal-risk.
2. Even though bone marrow assessments are routine for leukemia patients, the use of general anesthesia elevates the risk level.
3. The fact that the results are not shared with the treating oncologist and no therapeutic interventions are based on them indicates that the procedure is solely for research purposes, emphasizing the risk-benefit analysis.
4. Choice A is incorrect because the use of general anesthesia increases the procedure's risk level beyond routine.
5. Choice B is incorrect as the focus should be on the inherent risks of general anesthesia, not just the number of procedures performed.
6. Choice D is irrelevant to the risk assessment of the specific procedure and does not address the immediate safety concerns associated with general anesthesia.

The nurse is caring for a patient who was admitted to the coronary care unit following an acute myocardial infarction (AMI) and percutaneous coronary intervention the previous day. Teaching for this patient would include
A. when cardiac rehabilitation will begin.
B. the typical emotional responses to AMI.
C. information regarding discharge medications.
D. the pathophysiology of coronary artery disease.
Correct answer:
The correct answer is A: when cardiac rehabilitation will begin. This is important teaching for a patient following an AMI and PCI as cardiac rehabilitation plays a crucial role in improving recovery and reducing the risk of future cardiac events. It helps in improving physical strength, managing stress, and promoting overall heart health. By educating the patient about the timing and benefits of cardiac rehabilitation, the nurse is empowering the patient to actively participate in their recovery process.
Incorrect choices:
B: The typical emotional responses to AMI - While emotional support is important, teaching about emotional responses may not be as crucial as focusing on physical recovery through cardiac rehabilitation.
C: Information regarding discharge medications - Important, but not as immediate as cardiac rehabilitation for post-AMI recovery.
D: The pathophysiology of coronary artery disease - While education is important, understanding the pathophysiology may not be as pressing as knowing when to start cardiac rehabilitation for immediate recovery.
The nurse has finished reviewing the shift report on a cardiac unit. The nurse should plan to see which of the following assigned clients first?
A. A client with hypertrophic cardiomyopathy who is reporting dyspnea.
B. A client who had a cardiac caterterization and will be ambulating for the first time.
C. A client receiving antibiotics for bacterial endocarditis who is reporting anxiety and chest pain.
D. A client who is recovering from coronary artery bypass grafting (CABG) surgery with a temperature of 101 F.
Correct answer:
The correct answer is C because a client receiving antibiotics for bacterial endocarditis who is reporting anxiety and chest pain is showing signs of a potential cardiac emergency that requires immediate attention to prevent further complications. Chest pain and anxiety are red flags for cardiac issues such as myocardial infarction that could lead to life-threatening situations. Therefore, the nurse should prioritize this client to assess and intervene promptly.
Choice A is incorrect because dyspnea in a client with hypertrophic cardiomyopathy, while concerning, does not indicate an acute cardiac emergency that requires immediate attention.
Choice B is incorrect because a client who had a cardiac catheterization and will be ambulating for the first time does not exhibit urgent signs that necessitate immediate intervention compared to a client with chest pain and anxiety.
Choice D is incorrect because a temperature of 101 F in a client recovering from CABG surgery is not as concerning as chest pain and anxiety, which could indicate a cardiac complication.

Antiaggregants are used in disorders of brain circulation for:
A. Stimulation of the metabolic processes in neurons
B. Dilation of cerebral vessels
C. Improving the microcirculation in cerebral tissue
D. All the above
Correct answer:
The correct answer is C: Improving the microcirculation in cerebral tissue. Antiaggregants are used in disorders of brain circulation to prevent platelet aggregation and improve blood flow in the microcirculation of cerebral tissue. This helps to enhance oxygen and nutrient delivery to brain cells, ultimately improving brain function.
Rationale:
A: Stimulation of the metabolic processes in neurons is not the primary purpose of antiaggregants. While improved blood flow may indirectly support neuronal metabolism, the main goal of antiaggregants is to prevent clot formation and improve circulation.
B: Dilation of cerebral vessels is not the main mechanism of action for antiaggregants. Although vasodilation can enhance blood flow, antiaggregants primarily work by preventing platelet aggregation rather than directly causing vessel dilation.
D: All the above is incorrect because the primary purpose of antiaggregants in disorders of brain circulation is to improve microcirculation in cerebral tissue, not to stimulate metabolic processes in neurons or
A pediatric fellow is planning a project intended to decrease the incidence of acute chest syndrome among patients with sickle cell disease who are already admitted to the hospital for other reasons. The fellow discussed with her mentor whether the project proposal should be submitted for review by the Institutional Review Board (IRB). The mentor explains that, at their intuition, quality improvement activities do not require IRB review but research projects must be submitted to the IRB. Which of the following is NOT a relevant consideration in determining whether the project is research or quality improvement?
A. The aim to create new knowledge for the individual institution versus discovering new and generalizable knowledge
B. The chosen methodology which will include repeated Plan-Do-Study-Act cycles
C. The intent to publish the results in a peer reviewed hematology journal
D. The efforts to hold biases/confounders stable over time, rather than control for them with, for example, randomization
Correct answer:
The correct answer is C because the intent to publish results in a peer-reviewed journal is not a determining factor in distinguishing between quality improvement and research activities. Here's a step-by-step rationale:
1. Quality improvement focuses on improving processes within an institution to enhance patient care, while research aims to generate new knowledge that is generalizable beyond the institution.
2. The chosen methodology (B) such as using Plan-Do-Study-Act cycles is often associated with quality improvement projects to test and implement changes iteratively.
3. Efforts to hold biases stable over time (D) are more aligned with research, as quality improvement projects may not necessarily require controlling for biases like randomization.
4. The intent to publish in a peer-reviewed journal (C) can apply to both quality improvement and research projects, but the key factor in determining the need for IRB review is whether the project aims to generate generalizable knowledge (research) or improve local processes (quality improvement).
