Which of the following factors would the nurse identify as a modifiable risk factor for the development of varicose veins?

History of thrombophlebitis in both extremities

Mother and maternal grandmother had varicose veins

Employed as an over-the-road truck driver

Weight gained during past pregnancies

Answer and Explanation

The Correct Answer is C

A. History of thrombophlebitis in both extremities: This is a non-modifiable risk factor. Prior venous inflammation or clotting increases susceptibility to varicose veins but cannot be changed through lifestyle modifications.
B. Mother and maternal grandmother had varicose veins: Family history reflects genetic predisposition and is a non-modifiable factor. Inherited vein wall weakness increases risk but cannot be influenced by behavior.
C. Employed as an over-the-road truck driver: Prolonged sitting or standing restricts venous return and contributes to vein distension. This is modifiable through frequent leg movement, walking breaks, and use of compression stockings.
D. Weight gained during past pregnancies: Weight gain during previous pregnancies is a past event and no longer modifiable. Although pregnancy increases venous pressure, current lifestyle changes can't alter that history.

Correct Answer is A

Explanation

A. Release of endorphins and enkephalins: Massage stimulates the release of natural opioids such as endorphins and enkephalins. These neurotransmitters bind to opioid receptors in the brain and spinal cord, helping to reduce pain perception and promote a sense of well-being.
B. Interrupts pain perception: While massage may contribute to distraction, the primary mechanism involves biochemical modulation rather than directly interrupting the perception pathway. Pain perception is complex and multifactorial.
C. Keep the pain at a manageable level: This is a general goal of pain management but not a specific physiological mechanism of massage. It describes the outcome rather than the process by which massage works.
D. Floods the brain with alternative stimuli closes the spinal gate: This describes the gate control theory of pain, which applies more directly to techniques like transcutaneous electrical nerve stimulation (TENS) than to massage. Massage can influence gate control but primarily works through neurochemical pathways.

A. The spleen is lymphoid tissue in the upper chest that contains stem cells. B. The spleen assists with blood clotting. C. The spleen is a large lymph node and takes waste debris away. D. The spleen is a lymphatic structure and assists with phagocytosis

Correct Answer is D

Explanation

A. The spleen is lymphoid tissue in the upper chest that contains stem cells: The spleen is located in the left upper abdomen, not the chest, and it does not house hematopoietic stem cells. While it is lymphoid tissue, it does not primarily contain stem cells; stem cells are mainly found in the bone marrow.
B. The spleen assists with blood clotting: While the spleen stores platelets, its primary function is not clotting. It plays a secondary role in hemostasis but is more essential for filtering blood and immune responses.
C. The spleen is a large lymph node and takes waste debris away: The spleen is not a lymph node, although both are part of the lymphatic system. Lymph nodes filter lymph fluid, while the spleen filters blood. While the spleen does remove waste debris (through phagocytosis), it's not accurate to describe it as a large lymph node.
D. The spleen is a lymphatic structure and assists with phagocytosis: The spleen plays a critical role in immune defense by filtering blood, removing pathogens, and facilitating phagocytosis of old or damaged cells. Preserving it reduces the risk of overwhelming infections.
