Answer to Question 1
ANS: B
A positive Chvostek sign is representative of hypocalcemia or hypomagnesemia. Hypomagnese-mia is common with alcohol abuse. Hypocalcemia can be brought on by alcohol abuse and pan-creatitis (which also can be affected by alcohol consumption). Burn patients frequently experi-ence ECV deficit. Hyperparathyroidism causes hypercalcemia. Immobility is associated with hy-percalcemia.
Answer to Question 2
ANS: B
Usually the cause of respiratory alkalosis is a temporary event (e.g., an asthma or anxiety attack). The kidneys take about 24 hours to compensate for an event, so it is unlikely to see much if any compensation for respiratory alkalosis. Respiratory acidosis usually results from longer-term con-ditions such as chronic lung disease, narcotic overdose, or another event that causes respiratory depression. The kidneys still do not respond for about 24 hours, but usually the event is still oc-curring. For both metabolic imbalances, the respiratory system is quick to attempt to compensate: however, it may have difficulty sustaining that compensation.
