Correct Answer: A

Rationale: The correct answer is A because the postpartum patient who has had four saturated pads during the last 12 hours should receive further assessment. This indicates excessive postpartum bleeding (postpartum hemorrhage), which is a critical complication that requires immediate intervention to prevent complications like hypovolemic shock. Monitoring vital signs, assessing for signs of shock, evaluating uterine tone, and determining the cause of bleeding are crucial steps in managing postpartum hemorrhage. Choices B, C, and D are not the correct answers because: B: A patient with Class II heart disease complaining of frequent coughing is more likely experiencing cardiac-related issues and requires evaluation and management by a cardiologist. C: A patient with gestational diabetes and a fasting blood sugar level of 100 mg/dL is within the normal range and does not require immediate further assessment. D: A postcesarean patient with active herpes lesions on the labia requires appropriate management of the herpes infection but does not necess

Correct Answer: A

Rationale: The correct answer is A because several studies have indeed shown an association between BRCA-2 mutation and an increased risk of prostate cancer. BRCA-2 mutation is known to be linked to an increased risk of various cancers, including prostate cancer. This genetic mutation can be inherited and passed down through generations, leading to a higher likelihood of developing prostate cancer. Choices B, C, and D are incorrect because: B: HNPCC (Hereditary Nonpolyposis Colorectal Cancer) is not specifically associated with prostate cancer, and it is not an autosomal dominant mutation causing prostate cancer in men. C: TP53 gene is associated with other types of cancers, such as breast cancer, but not strongly linked to prostate cancer. D: Research has shown that genetics do play a role in the development of prostate cancer, contradicting the statement that genetics are unrelated to the disease.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): 1. The newer antihistamines, such as second-generation antihistamines like loratadine or cetirizine, are designed to cause less sedation compared to older antihistamines like diphenhydramine. 2. These newer antihistamines have a lower affinity for crossing the blood-brain barrier, reducing the sedative effects. 3. Therefore, suggesting that the newer antihistamines are different and cause less sedation is the best response to address the patient's concerns. Summary of Incorrect Choices: A. While some newer antihistamines may be combined with decongestants to offset drowsiness, this is not a consistent feature of all newer antihistamines. B. Developing tolerance to sedation after a few months is not a common or reliable response to antihistamines. D. Taking antihistamines at bedtime may help with sedation, but it does not address

Correct Answer: B

Rationale: The correct answer is B: Implement an automatic sign-off. This guideline helps reduce data entry errors by ensuring that all entries are completed and saved before exiting the system, thus maintaining confidentiality. Bypassing the firewall (A) would compromise data security. Creating a password with just letters (C) may not be secure enough. Using a programmed speed-dial key when faxing (D) is unrelated to reducing data entry errors or maintaining confidentiality.

Correct Answer: B

Rationale: The correct answer is B: Focusing the patient's immune system exclusively on the tumor. Biologic response modifiers (BRMs) work by enhancing the body's natural defenses to target and attack cancer cells specifically. This approach helps the immune system to recognize and destroy cancer cells while minimizing harm to normal cells. A: Promoting the synthesis and release of leukocytes - This is not the primary mechanism of action for BRMs. While leukocytes play a role in the immune response, BRMs target the immune system's response to tumors. C: Potentiating the effects of chemotherapeutic agents and radiation therapy - While some BRMs may be used in combination with these treatments, their primary mode of action is not to enhance the effects of chemotherapy or radiation therapy. D: Altering the immunologic relationship between the tumor and the patient - This choice is too broad and vague. BRMs specifically aim to direct the immune response towards targeting the tumor cells, rather than altering the overall immunologic relationship
