Correct Answer: C

Rationale: Carbamazepine (Tegretol) can suppress the bone marrow, leading to a decrease in the white blood cell count. A laboratory value of WBC 2,000 per cubic millimeter indicates a serious side effect of the drug. Choices A and D are within normal limits, while choice B is at the lower limit of normal. Therefore, choices A, B, and D are incorrect.

Correct Answer: A

Rationale: The correct answer is 'Birth-3 years old.' Children between birth and 3 years of age have the highest rates of victimization (at 16 per 1,000 children). This age group is most vulnerable due to their dependency and inability to report or protect themselves effectively. Child abuse can occur at any age, but statistics show that infants and toddlers are at the highest risk due to their developmental stage and reliance on caregivers. Choices B, C, and D are incorrect because while child abuse can happen at any age, the prevalence is highest among children in the 0-3 age group.

Correct Answer: B

Rationale: The correct answer is 'an individual's relationship with a higher power.' Spirituality is more about personal connection, beliefs, and experiences related to a higher power or force, whereas religion is often associated with organized practices, rituals, and doctrines within a specific faith community. Choice A is incorrect as spirituality goes beyond just believing in a higher power; it encompasses a personal connection. Choice C, 'organized worship,' is incorrect because spirituality can exist outside formal religious settings. Choice D is incorrect as it oversimplifies spirituality as merely a belief in an invisible energy or ideal, missing the relational aspect with a higher power.

Correct Answer: A

Rationale: AST, choice A, would be the least effective in diagnosing a myocardial infarction as it is not specific for this condition. Troponin, CK-MB, and myoglobin (choices B, C, and D) are more specific markers for myocardial infarction. Troponin is considered the gold standard due to its cardiac specificity. CK-MB is also specific to the heart, and its isoenzyme levels elevate post-heart damage. Myoglobin, although elevated in myocardial infarction, is not as specific as troponin and CK-MB and can also increase in conditions like burns and muscle trauma. Therefore, AST is the least effective choice for diagnosing a myocardial infarction.

Correct Answer: D

Rationale: Milieu therapy aims to provide routine daily experiences to clients. By offering a structured and predictable environment, it helps individuals feel safe and secure, reducing disruptive behaviors. Exploring the client's perception of reality (choice A) may be part of therapy but not the primary focus. Enhancing social interaction abilities (choice B) and addressing maladaptive behaviors (choice C) are important aspects of therapy but not the primary purpose of milieu therapy.
