Correct Answer: D

Rationale: The correct answer is D, marginal. Placenta previa is classified based on the proximity of the placental edge to the internal os. In a marginal placenta previa, the placental edge just reaches the internal os. This is a crucial distinction as it poses a higher risk for bleeding during labor. Total placenta previa covers the entire internal os, partial placenta previa partially covers the internal os, and low-lying placenta is when the placenta is close to but not covering the internal os. Therefore, D is correct as it accurately describes the specific position of the placenta edge in relation to the internal os in cases of marginal placenta previa.

Correct Answer: C

Rationale: The correct answer is C: Emotional and personality changes. In Huntington disease, neurodegeneration affects the brain, leading to changes in behavior, emotions, and personality. These changes are characteristic of the disease progression. Metastasis (A) refers to the spread of cancer, which is not associated with Huntington disease. Risk for stroke (B) is not a typical manifestation of Huntington disease. Pathologic bone fractures (D) are not directly related to the primary symptoms of Huntington disease. Thus, addressing emotional and personality changes is crucial in providing anticipatory guidance for individuals with Huntington disease.

Correct Answer: D

Rationale: The correct answer is D because treatment for HSV2 focuses on relieving symptoms since the virus cannot be cured. Antiviral medications can help manage outbreaks and reduce the frequency and severity of symptoms. Option A is incorrect as HSV2 typically presents as genital herpes, not cold sores on the lips (usually caused by HSV1). Option B is incorrect since antibiotics are ineffective against viruses. Option C is incorrect as HSV2 is most contagious during active outbreaks, making it important to practice safe sex to prevent transmission.

Correct Answer: D

Rationale: The correct answer is D: MRI. MRI is the most appropriate test for diagnosing spinal cord compression from a tumor as it provides detailed images of soft tissues, including the spinal cord and surrounding structures. It can accurately identify the location, size, and extent of the tumor. Anterior-posterior x-ray (A) is not as detailed and may not clearly show soft tissue abnormalities. Ultrasound (B) is not typically used for imaging the spinal cord and may not provide sufficient information. Lumbar puncture (C) is used to collect cerebrospinal fluid and is not helpful for diagnosing spinal cord compression from a tumor.

Correct Answer: D

Rationale: Rationale: Option D is correct because raising the head of the bed promotes a more natural position for defecation, allowing gravity to assist. This position helps align the rectum and anal canal, making it easier for the patient to have a bowel movement. Administering laxatives (Option C) may help, but adjusting the bed position is a non-invasive and more immediate intervention. Withholding pain medication (Option B) could lead to unnecessary discomfort for the patient. Administering a barium enema (Option A) is not indicated for addressing difficulty with defecation.
