foundations of nursing practice questions

Correct Answer: B

Rationale: The correct answer is B: Educational programs that focus on control and prevention. This intervention is the most crucial as it directly addresses the issue of the increasing incidence of HIV infection. By providing education on how to control and prevent the spread of HIV, the nurse can empower the community to take proactive measures to reduce transmission rates. A: Lifestyle actions that improve immune function may be helpful in general health promotion but do not directly target the prevention of HIV transmission. C: Appropriate use of standard precautions is important but is more focused on healthcare settings rather than community-wide prevention efforts. D: Screening programs for youth and young adults are valuable but may not be as effective as educational programs in preventing the spread of HIV.

Correct Answer: C

Rationale: The correct answer is C: Lobules and ducts. Each lobe of the breast consists of lobules, which are responsible for milk production, and ducts, which transport the milk to the nipple. This is essential for breastfeeding. Modified tendons and ligaments (choice A) are not present in the lobes of the breast. Connective tissue and smooth muscle (choice B) are important components of the breast but do not specifically make up the lobes. Endocrine glands and sebaceous glands (choice D) are not the primary elements within the lobes of the breast responsible for milk production and transport. The lobules and ducts are vital components for the functioning of the breast in lactation.

Correct Answer: D

Rationale: The correct answer is D: Immunoglobulin E. The atopic response in allergies is mainly mediated by IgE antibodies. IgE binds to allergens and triggers the release of histamine and other chemicals that cause allergic symptoms. IgA is mainly found in mucosal areas, IgM is involved in early immune responses, and IgG is important for long-term immunity. IgE is specifically associated with allergic reactions due to its role in sensitizing mast cells and basophils to allergens.

Correct Answer: D

Rationale: The correct answer is D because it addresses a crucial aspect of preoperative care for a patient undergoing a hysterectomy due to endometriosis. Emptying the bladder before surgery helps prevent urinary retention postoperatively. Placing a catheter during surgery ensures proper drainage and prevents bladder distention. This education topic is essential for the patient's comfort and well-being during and after the procedure. Choices A, B, and C are incorrect: A: Menstrual periods will not continue after a hysterectomy as the uterus is removed. B: Normal activity is usually restricted after a hysterectomy to promote healing. C: Hormone levels are affected after a hysterectomy, especially if the ovaries are also removed.

Correct Answer: A

Rationale: The correct answer is A: Hematologic spread. In this case, the cancer cells have traveled through the bloodstream to reach the bones and liver. This process is known as hematologic spread, where cancer cells enter the blood vessels and spread to distant organs. Lymphatic circulation (B) involves the spread of cancer cells through the lymphatic system, which is less likely in this scenario. Invasion (C) refers to cancer cells infiltrating nearby tissues, not distant organs. Angiogenesis (D) is the process of new blood vessel formation to support tumor growth, but it does not explain the spread of cancer cells to other organs.
