A nurse is collecting data from a client who has Graves' disease.
Which of the following signs should the nurse identify as an indication that the client is experiencing exophthalmos?

Step 1 is (150 lb × 1 kg ÷ 2.2 lb) × 250 units. This calculates the total units required. The answer is 17045.45 units.

Step 2 is 17045.45 units ÷ 10,000 units/mL = 1.7 mL.

The final calculated answer is 1.7 mL.

Choice A rationale

Numbness of the affected extremity is not a classic symptom of deep-vein thrombosis (DVT). DVT primarily affects venous circulation, causing symptoms like pain, swelling, and warmth, rather than sensory deficits like numbness, which are more indicative of nerve involvement or arterial issues.

Choice B rationale

Muscle spasms are not a hallmark sign of DVT. They are typically associated with muscular or neuromuscular issues. DVT symptoms are more focused on vascular changes such as pain, swelling, and increased warmth in the affected area due to impaired venous return.

Choice C rationale

Warmth of the affected extremity occurs due to localized inflammation caused by clot formation in the vein. The body’s inflammatory response to the thrombus leads to vasodilation and increased blood flow to the area, resulting in the sensation of warmth upon palpation.

Choice D rationale

An absent pedal pulse is not indicative of DVT, as this condition involves venous, not arterial, circulation. A missing pulse suggests arterial occlusion or peripheral vascular disease, distinct from venous thromboembolism like DVT.
