Answer to Question 1

C
Naloxone acts by blocking the action of opioids at opioid receptors. An opioid agonist would increase the effects of morphine. Naloxone does not affect serum pH or excretion of opioids. Na-loxone does not alter the sensitivity of opioid receptors.

Answer to Question 2

A
Acetaminophen poses a risk of fatal liver damage in alcoholics, because evidence indicates that even modest alcohol consumption combined with acetaminophen has this effect. Diazepam would probably be useful in this case, because it is used to aid alcohol withdrawal. However, di-azepam cannot be taken with alcohol, because the central nervous system (CNS) depressive ef-fects would be compounded. Likewise, morphine is safe as long as it is not given with alcohol. Thiamine is a vitamin that often is deficient in alcoholics, so thiamine would be indicated.
