What action(s) should a person take when they have an acute wrist sprain? (Select all that apply)
Stabilize the wrist with an elastic wrap.
Apply a warm pack to the affected wrist.
Keep the wrist elevated above the heart.
Frequently massage the affected wrist.
Rest the affected wrist until it is healed.
Correct Answer : A,C,E
Choice A reason: Stabilizing the wrist with an elastic wrap supports the injured ligaments, reducing movement and further damage. It promotes healing by maintaining alignment, making this a correct action for acute wrist sprain management.
Choice B reason: Applying a warm pack increases blood flow, which may worsen swelling in an acute sprain. Cold therapy is recommended to reduce inflammation and pain, making this choice incorrect for acute sprain management.
Choice C reason: Elevating the wrist above the heart reduces swelling by decreasing hydrostatic pressure, allowing fluid to drain from the injury site. This minimizes edema, making this a correct action for acute wrist sprain.
Choice D reason: Frequent massage may aggravate an acute sprain by increasing inflammation and pain. Rest and immobilization are preferred to promote healing, making this choice incorrect for acute wrist sprain management.
Choice E reason: Resting the wrist prevents further injury to damaged ligaments, allowing healing and reducing inflammation. Avoiding strain is critical in acute sprains, making this a correct action for wrist sprain recovery.

Correct Answer is C
Explanation
Choice A reason: Hemoglobin does not store oxygen in the lungs; it binds oxygen in the alveoli and releases it in tissues. Oxygen storage is minimal, and myoglobin in muscles serves this role, making this choice incorrect for hemoglobin’s primary function in gas exchange.
Choice B reason: Hemoglobin does not prevent carbon dioxide from entering the bloodstream. It binds carbon dioxide in tissues and transports it to the lungs for exhalation, facilitating gas exchange, not blocking it, making this choice incorrect for hemoglobin’s role.
Choice C reason: Hemoglobin binds oxygen in the lungs, forming oxyhemoglobin, and transports it via red blood cells to body tissues, where it releases oxygen for cellular metabolism. This is its primary role in gas exchange, making this the correct choice.
Choice D reason: Hemoglobin does not produce oxygen; oxygen is inhaled from the environment. Hemoglobin’s role is to transport oxygen, not synthesize it, making this choice incorrect as it misrepresents the physiological function of hemoglobin in gas exchange.
Correct Answer is D
Explanation
Choice A reason: Graves’ disease, a form of hyperthyroidism, does not typically cause decreased calcium. It may lead to hypercalcemia due to increased bone resorption from elevated thyroid hormone levels, which enhance osteoclast activity, making decreased calcium an incorrect laboratory finding for this condition.
Choice B reason: Graves’ disease is characterized by increased thyroid hormone production, including elevated T4 due to autoimmune stimulation of the thyroid. Decreased T4 is associated with hypothyroidism, not hyperthyroidism, making this choice incorrect as it contradicts the pathophysiology of Graves’ disease.
Choice C reason: Increased TSH is seen in primary hypothyroidism, where the thyroid is underactive. In Graves’ disease, TSH is typically decreased due to negative feedback from elevated thyroid hormones (T3 and T4), making this choice incorrect for the expected laboratory profile.
Choice D reason: Graves’ disease causes hyperthyroidism, with increased production of thyroid hormones, including T3, due to autoantibodies stimulating TSH receptors. Elevated T3 levels drive metabolic symptoms like weight loss and tachycardia, making this the correct laboratory finding for Graves’ disease.
