Through which of the following does lymph return to the blood?

Correct Answer: D

Rationale: Lymph returns to the blood circulation through the subclavian veins. The lymphatic system collects excess fluid, proteins, and waste products from the tissues and returns them to the bloodstream. The lymphatic vessels eventually converge into larger lymphatic ducts, and these ducts empty the lymph into the subclavian veins near the heart. From there, the lymph mixes with the blood, allowing it to circulate throughout the body and maintain fluid balance.

Correct Answer: D

Rationale: The major treatment modalities for breast cancer include surgery, radiotherapy, and chemotherapy. Each of these modalities plays a crucial role in the treatment plan for breast cancer patients:

Correct Answer: A

Rationale: To prevent infection in a patient with a subdural intracranial pressure monitoring system in place, the nurse should use aseptic technique for the insertion site. Aseptic technique involves maintaining a sterile field to prevent the introduction of microorganisms that could lead to infection. Using aseptic technique specifically for the insertion site helps reduce the risk of introducing pathogens into the patient's intracranial system, reducing the chances of infection. Additionally, maintaining a strict aseptic technique is crucial for preventing complications and ensuring patient safety when managing intracranial pressure monitoring systems.

Correct Answer: B

Rationale: Anemia is a condition characterized by a low red blood cell count or insufficient hemoglobin levels, resulting in decreased oxygen-carrying capacity in the blood. One of the nursing interventions for anemia is to promote a high protein, vitamin, and iron diet. Iron is essential for the production of hemoglobin, which carries oxygen in the blood. Including foods rich in iron, such as lean meats, dark leafy greens, beans, and fortified cereals, can help boost iron levels in the body. Additionally, consuming foods high in vitamin C can also aid in iron absorption. Protein is crucial for overall health and plays a role in red blood cell production. By encouraging a nutrient-rich diet, nurses can help support the body's ability to replenish its red blood cell supply and improve the symptoms associated with anemia.

Correct Answer: B

Rationale: Retinal examination of first-degree relatives is crucial to identify hereditary forms of retinoblastoma.
