The nurse is caring for a patient newly diagnosed with a primary brain tumor. The patient asks the nurse where his tumor came from. What would be the nurses best response?

Correct Answer: C

Rationale: The correct answer is C because primary brain tumors originate from cells within the brain itself. These tumors develop from abnormal growth of brain cells. Choice A is incorrect as primary brain tumors do not come from outside the central nervous system (CNS). Choice B is incorrect as primary brain tumors do not typically start in glands. Choice D is incorrect as primary brain tumors do not arise from nerve tissue elsewhere in the body. In summary, the nurse should explain to the patient that the tumor originated from cells within his brain to provide accurate information about the nature of primary brain tumors.

Correct Answer: B

Rationale: Correct Answer: B - Use of a raised toilet seat Rationale: A raised toilet seat helps the patient with Parkinson's disease by providing additional height, making it easier for them to transition from sitting to standing. This aids in improving mobility and reducing the risk of falls. Furthermore, the raised seat can also promote proper positioning for bowel elimination, making the process more comfortable and effective. Incorrect Choices: A: Using a bedpan does not address the issue of transitioning from sitting to standing, nor does it aid in improving bowel elimination for the patient. C: Sitting quietly on the toilet every 2 hours may not directly address the physical challenges the patient is facing in transitioning from sitting to standing. D: Following the outlined bowel program is important, but it does not specifically address the physical support needed to transition from sitting to standing for a patient with Parkinson's disease.

Correct Answer: B

Rationale: The correct answer is B: Total placenta previa. In this condition, the placenta completely covers the cervix, posing a risk of severe bleeding during vaginal delivery. Cesarean birth is necessary to avoid potential life-threatening complications for both the mother and the baby. Partial abruptio placentae (choice A) involves premature separation of the placenta, but it doesn't always require a cesarean birth. Ectopic pregnancy (choice C) occurs when the fertilized egg implants outside the uterus, typically requiring surgical intervention but not always a cesarean birth. Eclampsia (choice D) is a serious condition characterized by high blood pressure and seizures, but it doesn't always necessitate cesarean birth unless there are other complications that require it.

Correct Answer: D

Rationale: The correct answer is D because the patient's symptoms of pounding headache, visual changes, and epigastric pain are classic signs of worsening preeclampsia, indicating a significant increase in blood pressure and potential progression to eclampsia (seizures). Immediate medical intervention is crucial to prevent complications. A: Gastrointestinal upset does not explain the combination of symptoms presented. B: Magnesium sulfate is used to prevent seizures in preeclampsia but does not cause these specific symptoms. C: Anxiety does not typically present with the specific physical symptoms mentioned.

Correct Answer: A

Rationale: The correct answer is A: decreased fibrinogen. In disseminated intravascular coagulation (DIC), there is widespread activation of coagulation leading to consumption of clotting factors like fibrinogen, resulting in decreased levels. Platelets are usually decreased, not increased, in DIC. Hematocrit may be elevated due to hemoconcentration but not directly related to DIC. Thromboplastin time would be prolonged, not decreased, in DIC due to consumption of clotting factors.
