The majority of people function in a relatively healthy manner. What can most strongly diminish their functional capacity?

A. Projection involves attributing one’s own unacceptable feelings or thoughts onto another person. However, in this case, the patient’s tantrum and crying are more about their own inability to handle the refusal rather than projecting feelings onto others.
B. Repression is a defense mechanism where distressing thoughts or feelings are unconsciously blocked from entering awareness. For instance, if the patient were to push aside their feelings of disappointment about not receiving the diet pills without expressing them, that would be repression.
C. Denial involves refusing to accept reality or facts that are distressing or threatening. However, the primary behavior in this situation is the tantrum and crying, which are more indicative of another defense mechanism rather than outright denial.
D. Regression is a defense mechanism where an individual reverts to behaviors characteristic of an
earlier developmental stage in response to stress or conflict. The patient’s crying and tantrum can be seen as regressive behavior because it reflects a return to more childlike or immature ways of handling frustration, similar to how a child might react to not getting what they want.

A. Patients on lithium do not need to avoid aged cheese and red wine specifically. The main dietary advice is to avoid significant changes in salt intake rather than specific foods like aged cheese or red wine.
B. Skin eruptions are not a common concern specifically linked to lithium therapy. While monitoring for side effects is important, skin changes are not typically a primary focus in lithium management.
C. Lithium use is not directly associated with routine blood pressure monitoring unless there is a specific concern about blood pressure or other cardiovascular issues. While monitoring blood pressure is important for overall health, it is not a specific requirement for patients on lithium unless there are other related concerns.
D. Monitoring blood levels of lithium is essential for managing the risk of toxicity and ensuring therapeutic efficacy. Lithium has a narrow therapeutic range, and regular blood tests are necessary to adjust dosages and avoid side effects.
