A client asks the nurse about the function that the lymph system plays in the body. Which of the following would be most appropriate for the nurse to include when responding to the client?

It filters harmful substances from the body.

It drains capillary blood from the circulation.

It produces protective antibodies.

It manufactures T lymphocytes.

Answer and Explanation

The Correct Answer is A

A. It filters harmful substances from the body: The lymphatic system plays a crucial role in filtering lymph fluid and removing harmful substances, such as pathogens and toxins, through lymph nodes.

B. It drains capillary blood from the circulation: The lymphatic system does not directly drain capillary blood; instead, it collects interstitial fluid and returns it to the bloodstream.

C. It produces protective antibodies: Antibodies are produced by B lymphocytes in the immune system, not directly by the lymphatic system itself.

D. It manufactures T lymphocytes: While the lymphatic system is involved in the maturation and function of T lymphocytes, their manufacture occurs in the bone marrow and thymus rather than the lymphatic system itself.

Correct Answer is B

Explanation

A. Facial, Trigeminal, Vestibulocochlear: The Facial nerve (VII) controls facial expressions, the Trigeminal nerve (V) is involved in facial sensation, and the Vestibulocochlear nerve (VIII) handles hearing and balance, none of which are directly related to eye movements.

B. Oculomotor, Trochlear, and Abducens: The Oculomotor nerve (III) controls most eye movements, the Trochlear nerve (IV) controls the superior oblique muscle for downward and outward movements, and the Abducens nerve (VI) controls the lateral rectus muscle for lateral eye movement.

C. Spinal Accessory, Facial, Trigeminal: The Spinal Accessory nerve (XI) controls neck and shoulder movements, while the Facial nerve (VII) and Trigeminal nerve (V) are not involved in eye movements.

D. Glossopharyngeal, Vagus, Hypoglossal: The Glossopharyngeal nerve (IX) is involved in taste and salivation, the Vagus nerve (X) affects parasympathetic functions, and the Hypoglossal nerve (XII) controls tongue movements, none of which are related to eye movements.

A. Stasis ulceration B. Arterial occlusion C. Dependent edema D. Venous insufficiency

Correct Answer is D

Explanation

A. Stasis ulceration: While stasis ulcers can occur in the context of venous insufficiency, the description of warm skin and brown pigmentation more directly suggests venous insufficiency.

B. Arterial occlusion: This condition typically presents with cold, pale skin and possible pain or cramping, rather than warm skin and pigmentation.

C. Dependent edema: Dependent edema involves swelling due to fluid accumulation but does not necessarily cause pigmentation changes around the ankles.

D. Venous insufficiency: Warm skin and brown pigmentation around the ankles are indicative of venous insufficiency, a condition where blood flow in the veins is impaired, leading to these symptoms.
