Answer to Question 1
ANS: B
Physical dependence is an involuntary response to the pharmacologic characteristics of drugs such as opioids or alcohol. A person can be physically dependent on a narcotic/drug without being addicted; for example, patients who use opioids to control pain need increasing doses to achieve the same effect. Dependence is a physiologic response; it is not culturally determined or subject to voluntary control.
Answer to Question 2
ANS: C
Physiologic characteristics of children with depression include change in appetite resulting in weight loss or gain, nonspecific complaints of not feeling well, alterations in sleeping pattern, insomnia or hypersomnia, and constipation. Children who are depressed have sad facial expressions with absence or diminished range of affective response. These children withdraw from previously enjoyed activities and engage in solitary play or work with a lack of interest in play. A lack of interest is seen in doing homework or achieving in school, resulting in lower grades in children who are depressed.
