Correct Answer: C

Rationale: The correct answer is C (900 mL) because the weight of 900 g corresponds to a blood loss of the same amount in milliliters. Blood density is close to that of water, so 1 g ? 1 mL. Therefore, a blood-soaked peripad weighing 900 g indicates a blood loss of 900 mL. Choice A (1800 mL) is incorrect as it doubles the weight instead of converting it to milliliters. Choice B (450 mL) is incorrect as it halves the weight. Choice D (90 mL) is incorrect as it divides the weight by 10, which is too small for the blood loss indicated.

Correct Answer: D

Rationale: The correct answer is D: Frequent douching. Douching disrupts the natural balance of vaginal flora, making the environment more susceptible to infections. High estrogen levels (A) can actually protect against vaginal infections. Late menarche (B) and nonpregnant state (C) are not direct risk factors for vaginal infections. In summary, frequent douching is the most significant risk factor as it disrupts the vaginal microbiome.

Correct Answer: D

Rationale: The correct answer is D: Bilateral mastectomy. This intervention involves removing both breasts to reduce the risk of developing breast cancer in the future. For a woman with a history of breast cancer in one breast, opting for bilateral mastectomy can significantly decrease the likelihood of cancer recurrence. This proactive approach is often recommended for individuals with a high risk of developing breast cancer. Explanation for why the other choices are incorrect: A: More aggressive chemotherapy - Chemotherapy is typically used to treat existing cancer cells, not as a prophylactic measure to prevent cancer. B: Left mastectomy - This option only removes the affected breast, not addressing the risk of cancer developing in the other breast. C: Radiation therapy - While radiation therapy can be used as part of the treatment for breast cancer, it is not a prophylactic measure to prevent future cancer development in the contralateral breast.

Correct Answer: B

Rationale: The correct order is B: Kidney, ureters, bladder, urethra. 1. Kidneys filter blood and produce urine. 2. Ureters transport urine from kidneys to bladder. 3. Bladder stores urine until expelled. 4. Urethra carries urine from bladder out of the body. Other choices are incorrect because they do not follow the anatomical flow of urine through the urinary system.

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. Clear, watery fluid draining from the ear post-accident indicates a possible cerebrospinal fluid (CSF) leak, a serious condition requiring immediate medical attention to prevent complications such as meningitis. 2. CSF leak can result from a basilar skull fracture, common in head injuries like motorcycle accidents. 3. Prompt reporting of this finding by the nurse is crucial for timely intervention and prevention of potential life-threatening complications. Summary: A: Visualizing the malleus during otoscopic examination is normal and not an immediate concern in this scenario. B: A pearly gray tympanic membrane is a normal finding and does not indicate a serious issue post-accident. C: Tenderness in the mastoid area may suggest injury but is not as urgent as clear, watery fluid drainage indicative of a CSF leak.
