Answer and Explanation

The Correct Answer is D

A. Occurs when you are physically and psychologically exhausted: An aura is a specific set of symptoms that precedes the headache, not related to exhaustion.

B. Occurs in the postdrome and causes you to feel sleepy and weak: The postdrome phase is after the headache, and an aura occurs before the headache.

C. Is a trigger such as a stressful event, that is the cause of the headache: An aura is not a trigger but rather a symptom experienced before the headache begins.

D. An aura is a warning, such as an unpleasant smell, before the headache begins: An aura is a neurological phenomenon that can include visual disturbances, unusual smells, or other sensory changes occurring before the onset of a migraine.

Correct Answer is A

Explanation

A. Paralytic ileus: Paralytic ileus is a common complication of major abdominal surgery and prolonged bed rest. It is a temporary cessation of normal bowel peristalsis, leading to a lack of bowel sounds and the inability to pass gas or stool.

B. Esophageal dysplasia: This condition refers to abnormal changes in the cells of the esophagus, typically related to chronic gastroesophageal reflux disease (GERD), not prolonged bed rest.

C. Gastroparesis: This is a condition in which the stomach cannot empty itself of food in a normal fashion, often related to diabetes or damage to the vagus nerve. It is not a direct result of prolonged bed rest.

D. Paralytic ileum: This should refer to "paralytic ileus."

A. An increased serum calcitonin level. B. An increased number of osteocytes. C. Elevated plasma magnesium levels. D. An increased parathyroid hormone (PTH) level.

Correct Answer is D

Explanation

A. An increased serum calcitonin level: Calcitonin is involved in lowering blood calcium levels, so increased levels would not indicate hypercalcemia but rather a compensatory mechanism to lower calcium.

B. An increased number of osteocytes: Osteocytes are bone cells, and their number is not a direct indicator of hypercalcemia. Osteoclasts and osteoblasts are more relevant to bone metabolism.

C. Elevated plasma magnesium levels: Elevated magnesium levels are not specifically indicative of hypercalcemia and can be related to other conditions.

D. An increased parathyroid hormone (PTH) level: Hypercalcemia can be associated with increased PTH levels, particularly in primary hyperparathyroidism. Elevated PTH can lead to increased calcium release from bones.
