Correct Answer: B

Rationale: The correct answer is B because starting birth control pills does not protect against HIV transmission to the baby during pregnancy. The other choices demonstrate understanding of HIV transmission risks and prevention methods. A shows awareness of vertical transmission, C recognizes that not all babies born to HIV-positive mothers are infected, and D acknowledges the potential need for a C-section to reduce transmission risk. Starting birth control pills is unrelated to preventing mother-to-child HIV transmission during pregnancy.

Correct Answer: A

Rationale: The correct answer is A: Deficient fluid volume related to osmotic diuresis. With a serum glucose level of 618mg/dl, the client is likely experiencing diabetic ketoacidosis, leading to excessive urination (osmotic diuresis) and dehydration. The priority is to address fluid volume deficit to prevent hypovolemic shock. The other options are not the priority because: B: Decreased cardiac output is a result of the increased heart rate, not the primary issue. C: Imbalanced nutrition is important but not as urgent as fluid volume deficit. D: Ineffective thermoregulation is a concern but not the priority in this scenario.

Correct Answer: C

Rationale: Elevating the head of the bed is the correct answer because it helps to promote venous drainage, reduce cerebral edema, and decrease intracranial pressure (ICP). By positioning the patient with the head elevated, gravity assists in preventing further increases in ICP. Encouraging fluids may lead to fluid overload and exacerbate cerebral edema. Providing physical therapy and frequent repositioning may increase ICP by causing unnecessary movement and potential strain on the patient's head and neck.

Correct Answer: C

Rationale: The correct answer is C: Human, T-cell lymphotrophic virus, as it is the causative agent for HIV/AIDS. This virus specifically targets and infects the body's T-cells, weakening the immune system. Trichomonas vaginalis, Treponema pallidum, and Chlamydia trachomatis are all different pathogens that do not cause HIV/AIDS. Trichomonas vaginalis is a protozoan parasite that causes trichomoniasis, Treponema pallidum causes syphilis, and Chlamydia trachomatis causes chlamydia. Therefore, the correct answer is C based on the specific viral agent responsible for HIV/AIDS.

Correct Answer: D

Rationale: The correct answer is D: Sitting up leaning slightly forward. This position helps prevent blood from flowing back into the throat, reducing the risk of choking and aspiration. It also allows for better drainage of blood out of the nose. Lying down with feet elevated (choice A) can increase blood flow to the head and worsen the nosebleed. Sitting up with neck extended (choice B) can lead to blood flowing into the throat. Lying down with a small pillow under the head (choice C) may cause blood to flow backward.
