Answer and Explanation

The Correct Answer is D

A. Low T4, High TSH: This pattern is seen in primary hypothyroidism, where the thyroid gland is underactive.

B. Low T4, high calcitonin: This choice is unrelated to the typical lab findings in Graves' disease. Calcitonin levels are not commonly assessed in thyroid disorders like Graves' disease.

C. High PSA and estrogen levels: PSA (Prostate-Specific Antigen) and estrogen levels are unrelated to Graves' disease, which is an autoimmune hyperthyroid condition.

D. High T4, low TSH: Graves' disease is characterized by hyperthyroidism, where T4 (thyroxine) levels are elevated, and TSH (Thyroid-Stimulating Hormone) levels are suppressed due to the negative feedback mechanism.

Correct Answer is D

Explanation

A. Several episodes of black and tarry stools: This indicates melena, which is typically associated with upper gastrointestinal bleeding, not specifically Crohn's disease.

B. Several episodes of hematochezia per day: Hematochezia (fresh blood in stools) can occur in Crohn's disease due to inflammation and ulceration in the intestines.

C. Post-alcohol ingestion epigastric pain: This is more commonly associated with gastritis or peptic ulcer disease, not Crohn's disease.

D. An oral temperature of 102°F: While fever can occur in Crohn's disease during acute flare-ups, it is not a specific or definitive symptom of the condition. The primary symptoms are gastrointestinal in nature, such as abdominal pain and altered bowel habits.

A. Elevating the head of the bed promotes venous return and helps increase the ICP. B. Elevation of the head of the bed aids in maintaining cerebral perfusion. C. Elevation of the head of the bed will increase intracranial pressure (ICP). D. The nurse should keep the head of the bed flat to ensure adequate arterial circulation.

Correct Answer is B

Explanation

A. Elevating the head of the bed promotes venous return and helps increase the ICP: This is incorrect. Elevation of the head of the bed helps to decrease intracranial pressure (ICP) by promoting venous drainage rather than increasing it.

B. Elevation of the head of the bed aids in maintaining cerebral perfusion: Elevating the head of the bed helps to decrease ICP, which in turn aids in maintaining adequate cerebral perfusion pressure.

C. Elevation of the head of the bed will increase intracranial pressure (ICP): This is incorrect. Elevation of the head of the bed is intended to reduce ICP, not increase it.

D. The nurse should keep the head of the bed flat to ensure adequate arterial circulation: This is incorrect. Keeping the head of the bed flat can increase ICP, which is counterproductive in managing intracranial pressure.
