Correct Answer: B

Rationale: The correct answer is B: Fluorouracil (5-fluorouracil, 5 FU [Fluoroplex]). Fluorouracil is commonly used in chemotherapy for liver cancer to inhibit cancer cell growth. It is a pyrimidine analog that interferes with DNA synthesis. Fluoxymesterone (
A) is an androgen used in hormone replacement therapy, not in liver cancer treatment. Tamoxifen (
C) is an antiestrogen used in breast cancer treatment, not liver cancer. Megestrol (
D) is a progestin used in hormone therapy for breast cancer and endometrial cancer, not liver cancer.
Therefore, the correct choice is B as it directly targets cancer cell growth in liver cancer treatment.

Correct Answer: B

Rationale: The correct answer is B, a high protein, vitamin, and iron diet, as it directly addresses the nutritional deficiencies associated with anemia. Proteins aid in the production of red blood cells, while iron and vitamins are essential for hemoglobin synthesis. Medical therapy (
A) typically involves medications or blood transfusions, not dietary changes. Fluid therapy (
C) may be used for certain types of anemia, but it is not a primary intervention. Chemotherapy (
D) is not indicated for the treatment of anemia, as it is used for cancer treatment.
Therefore, choice B is the most appropriate intervention for anemia.

Correct Answer: B

Rationale:
Step 1: Crowded living conditions do not directly increase the risk of lung cancer.

Step 2: Passive smoke (choice
A) and air pollution (choice
C) contain carcinogens linked to lung cancer.

Step 3: Diet low in fruits and vegetables (choice
D) may lead to poor immune function, potentially impacting cancer risk.

Step 4: In summary, crowded living conditions do not contribute to lung cancer risk compared to the other choices.

Correct Answer: B

Rationale:
Step 1: High cholesterol levels contribute to the buildup of plaque in arteries, leading to atherosclerosis and increasing the risk of coronary artery disease.

Step 2: Atherosclerosis can result in a blockage of blood flow to the heart, causing a myocardial infarction (MI).

Step 3: Age is a risk factor for CAD but not directly linked to MI development.

Step 4: Medication usage may impact risk factors but is not a direct cause of MI.

Step 5: Gender can influence risk but is not the primary factor in MI development.

Correct Answer: A

Rationale: The correct answer is A: Human Needs (Maslow) model. The nurse is using a systematic approach based on Maslow's Hierarchy of Needs, which includes physiological, safety, love/belonging, esteem, and self-actualization needs. This model organizes assessment data by prioritizing these universal life requirements.

Incorrect choices:
B: Functional Health Patterns model - This model focuses on 11 functional health patterns, not the hierarchy of universal life requirements.
C: Human Response Patterns model - This model focuses on the individual's response to stressors, not prioritizing universal life requirements.
D: Body System model - This model focuses on assessing specific body systems, not the holistic approach of addressing all life requirements.
