No drugs cure this condition. Emphasis is put on delaying the onset of severe symptoms. Which of the following does NOT help improve Alzheimer's?

Correct Answer: A

Rationale: Smoking is a harmful habit that is known to contribute to a variety of health problems, including heart disease, lung disease, and cancer. Smoking does not provide any benefits for Alzheimer's patients and, in fact, can worsen the condition due to its negative impact on overall health. Therefore, smoking does not help improve Alzheimer's and may exacerbate the symptoms and complications associated with the disease.

Correct Answer: B

Rationale: During the acute phase response, C-reactive protein (CRP) primarily serves to activate the complement system. CRP binds to phosphocholine on the surface of pathogens, allowing for the activation of the classical pathway of the complement system. This leads to the recruitment of immune cells, opsonization of pathogens, and enhancement of phagocytosis. The activation of the complement system by CRP plays a crucial role in the host defense against infections, aiding in the elimination of pathogens and the resolution of inflammation.

Correct Answer: C

Rationale: The clinical presentation described with fever, headache, maculopapular rash starting on the face and spreading to the trunk and extremities, along with leukopenia and thrombocytopenia suggests a likely diagnosis of Rocky Mountain spotted fever (RMSF), which is caused by the bacterium Rickettsia rickettsii.

Correct Answer: B

Rationale: Leaving the side rails down is one of the most common occurrences that can lead to a patient fall. Side rails are important safety measures designed to prevent patients from falling out of bed. When the side rails are left down, the patient is at a higher risk of accidentally rolling out of bed and falling. It is crucial for healthcare providers to always ensure that the side rails are up and secure to help prevent patient falls.

Correct Answer: A

Rationale: The right being violated in this scenario is the right to obtain from his physician complete current information concerning his diagnosis, treatment, and prognosis. Patients have the right to be fully informed about their health status and to understand the details of their condition, treatment options, and likely outcomes. Withholding this information can prevent the patient from participating in their own care decisions and can violate their autonomy and right to make informed choices about their health.

Correct Answer: D

Rationale: The presentation of sudden-onset severe headache, vomiting, and altered mental status, along with the presence of a berry-shaped aneurysm on imaging, point towards a diagnosis of subarachnoid hemorrhage. The most common cause of a subarachnoid hemorrhage is the rupture of a saccular (berry) aneurysm, which commonly occurs at the junction of the anterior communicating artery and anterior cerebral artery. The sudden headache is often described as the "worst headache of my life" and is typically associated with nausea and vomiting. Altered mental status may be present due to the effects of increased intracranial pressure and possible associated brain injury. It is important to promptly diagnose and manage subarachnoid hemorrhage to prevent complications such as vasospasm, rebleeding, and ischemic deficits.

Correct Answer: A

Rationale: In the case of a woman in active labor with placenta previa, the priority nursing intervention is to prepare for an immediate cesarean section. Placenta previa is a condition in which the placenta covers part or all of the cervix, which can lead to severe bleeding during labor and delivery. The risk of hemorrhage is significant, making a cesarean section the safest option for both the mother and the baby in this situation. It is crucial to act promptly to prevent complications and ensure the well-being of both the mother and the baby. Administering intravenous oxytocin to augment labor or inserting a Foley catheter to monitor urine output would not address the immediate risk of hemorrhage associated with placenta previa. Implementing bed rest and continuous fetal monitoring may be part of the overall care plan but not the priority intervention in this urgent situation.

Correct Answer: A

Rationale: The patient presents with gradual, painless visual field loss in both eyes, particularly in the peripheral vision, which is characteristic of glaucoma. The elevated intraocular pressure (IOP) on tonometry further supports a diagnosis of glaucoma. Open-angle glaucoma is the most common type of glaucoma and typically presents insidiously with a slow progression of vision loss. In open-angle glaucoma, the drainage angle of the eye remains open but becomes less efficient over time, leading to increased intraocular pressure and optic nerve damage. This results in peripheral visual field loss. Closed-angle glaucoma, on the other hand, presents more acutely with sudden eye pain, redness, and blurred vision due to a sudden increase in intraocular pressure from a blocked drainage angle. Age-related macular degeneration and diabetic retinopathy typically do not present with elevated IOP or peripheral visual field loss.

Correct Answer: A

Rationale: Endometriosis is a condition characterized by the abnormal growth of endometrial tissue outside the uterus. One common symptom of endometriosis is excessive menstrual bleeding, known as menorrhagia. This excessive bleeding is due to the presence of endometrial tissue in abnormal locations, leading to inflammation, scarring, and blood accumulation. In severe cases, endometriosis can lead to the formation of adhesions, cysts, and scar tissue, causing significant pain and fertility issues for affected individuals. Endometrial hyperplasia, leiomyomas (uterine fibroids), and adenomyosis are other gynecological conditions, but they do not involve the abnormal proliferation of endometrial tissue outside the uterus like endometriosis does.
