(MCQS 346 –348):Cystadenocarcinoma of the pancreas is most likely to present at

Question:346
Correct Answer: I
Explanation:
Cystadenocarcinoma generally arises in females between the ages of 40 and 60, and it represents less than 2% of all pancreatic exocrine neoplasms. Cystadenocarcinomas often present as cystic masses in the body and tail of the pancreas, associated with abdominal and back pain. CT scan of the abdomen typically reveals a tumor mass with associated cysts, which may be misinterpreted as representing a pancreatic pseudocyst.

Question:347
Correct Answer: D
Explanation:
Primary hyperparathyroidism is resulting from overactivity of one or more parathyroid glands. This is characterized by hypercalcemia, hypophosphatemia and hypercalciuria. It is caused usually by an adenoma, less commonly by primary hyperplasia. Calcium stones in the urinary tract are frequently present. Symptoms in primary hyperparathyroidism such as fatigability, anorexia and weakness result from the hypercalcemia. Serum parathyroid hormone level can be determined accurately by radioimmunoassay or immunoradiometric assay.
Question:348
Correct Answer: H
Explanation:
Following sedation, the patient is placed in a head-down tilt of approximately 20 degrees for groin hernias but with no tilt when other hernias are treated. A pillow may be placed under the buttocks. For infants, the legs should be swaddled and secured to prevent slippage. This technique is successful in spontaneously reducing 80% of pediatric incarcerated hernias over a 2-hour period without manipulation. In addition, the application of a cold pack or a padded ice bag to the hernia, covered with cloth or gauze (to prevent cold injury to the skin), may reduce local blood flow and diminish intraluminal gas pressure while the analgesic is taking effect.
