A patient presents with sudden-onset severe headache, vomiting, and altered mental status. Imaging reveals a noncontrast-enhancing hemorrhagic lesion within the subarachnoid space. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Ischemic stroke
- B. Subdural hematoma
- C. Intracerebral hemorrhage
- D. Subarachnoid hemorrhage
Correct Answer: D
Rationale: The correct answer is D: Subarachnoid hemorrhage. This condition presents with sudden-onset severe headache, vomiting, and altered mental status due to bleeding in the subarachnoid space. This type of hemorrhage is typically noncontrast-enhancing on imaging.
A: Ischemic stroke does not typically present with sudden-onset severe headache and vomiting.
B: Subdural hematoma usually presents with a slower onset of symptoms and often develops after head trauma.
C: Intracerebral hemorrhage presents with focal neurological deficits rather than altered mental status and vomiting.
In summary, based on the sudden onset of symptoms, imaging findings, and clinical presentation, subarachnoid hemorrhage is the most likely diagnosis in this case.

The nurse specialist explains that chemotherapyis extremely toxic to the bone marrow and the patient may develop thrombocytopenia. What is the priority goal of the nurse? To take precautions to control _______.
- A. Bleeding
- B. Infection
- C. Hypotension
- D. diarrhea
Correct Answer: A
Rationale: The correct answer is A: Bleeding. Chemotherapy can lead to low platelet counts (thrombocytopenia), increasing the risk of bleeding. The priority goal of the nurse is to prevent bleeding by taking precautions such as avoiding invasive procedures, using soft toothbrushes, and monitoring for signs of bleeding. Infection (B) is important but not the priority as bleeding can be life-threatening. Hypotension (C) is not directly related to thrombocytopenia. Diarrhea (D) is a potential side effect of chemotherapy but is not the priority when considering thrombocytopenia.
Nurse Victor reviews the medical history of patient Mila. Which of the following conditions is the MOST common cause of cardiogenic shock?
- A. Decreased hemoglobin level
- B. Acute myocardial infarction (MI)
- C. Hypotension
- D. Coronary artery disease
Correct Answer: B
Rationale: The correct answer is B: Acute myocardial infarction (MI) is the most common cause of cardiogenic shock. During an MI, there is significant damage to the heart muscle, leading to a decrease in cardiac output and subsequent shock. This results in inadequate tissue perfusion and oxygen delivery. Choices A, C, and D are incorrect because decreased hemoglobin level (A) may lead to anemia but is not the most common cause of cardiogenic shock. Hypotension (C) is a symptom of shock, not the cause. Coronary artery disease (D) is a risk factor for MI but not the direct cause of cardiogenic shock.
A surgeon accidentally cuts his patient's bladder while attempting to remove his appendix. The surgeon could be guilty of _________
- A. Battery
- B. Negligence
- C. Malpractice
- D. Tort
Correct Answer: C
Rationale: The correct answer is C: Malpractice. Malpractice refers to professional negligence or failure to perform duties according to accepted standards of practice. In this scenario, the surgeon's act of cutting the patient's bladder during an appendectomy could be considered a breach of duty and failure to provide the expected standard of care, which falls under malpractice. Battery (A) involves intentional harmful or offensive contact without consent. Negligence (B) is the failure to exercise reasonable care, but in this case, it was more than just a lack of care. Tort (D) refers to a civil wrong that causes harm, but malpractice is a specific type of tort related to professional negligence.
Which of the following is a characteristic of qualitative research?
- A. Deductive process
- B. Fixed research design
- C. Control over the context
- D. Inductive process
Correct Answer: D
Rationale: The correct answer is D: Inductive process. Qualitative research typically involves an inductive approach, where researchers gather data, analyze patterns, and develop theories or hypotheses based on the observed data. This allows for exploration and discovery of new insights.
A) Deductive process is not a characteristic of qualitative research, as deductive reasoning involves starting with a hypothesis and testing it with data.
B) Fixed research design is not common in qualitative research, which often uses flexible and adaptive designs to accommodate emergent findings.
C) Control over the context is not a key characteristic of qualitative research, as it often involves studying real-world settings with natural contexts rather than controlled environments.
In summary, the inductive process is a key characteristic of qualitative research as it allows for exploration and theory development based on observed data, distinguishing it from deductive approaches, fixed designs, and controlled contexts.
A pregnant woman presents with severe abdominal pain and passage of tissue at 12 weeks gestation. On examination, the cervix is partially dilated, and products of conception are protruding through the cervical os. Which of the following conditions is the most likely cause of these symptoms?
- A. Ectopic pregnancy
- B. Incomplete abortion
- C. Placenta previa
- D. Gestational trophoblastic disease
Correct Answer: B
Rationale: In this scenario, the pregnant woman is presenting with severe abdominal pain, passage of tissue, and cervical dilation with products of conception protruding through the cervical os at 12 weeks gestation. These are classic signs and symptoms of an incomplete abortion. Incomplete abortion occurs when not all of the products of conception are expelled from the uterus. It can present with vaginal bleeding, abdominal pain, cervical dilation, and passage of tissue. The management of incomplete abortion may involve expectant, medical, or surgical options depending on the clinical context and the patient's condition.
