1. Blood cells are produced in the organs of the _______ system.
- A. endocrine
- B. skeletal
- C. superior to
- D. inferior to
Correct answer: superior to
Rationale: Blood cells are produced in the organs of the hematopoietic system. The correct answer is 'superior to' as this refers to the location of the organs responsible for blood cell production, typically bone marrow found in bones such as the vertebrae, ribs, and skull. 'Endocrine' (Choice A) refers to a different system responsible for hormone production. 'Skeletal' (Choice B) relates to bones but not specifically to the production of blood cells. Choices C and D, 'superior to' and 'inferior to,' do not make sense in the context of blood cell production and are incorrect.
2. During the detoxification stage, it is a priority for the nurse to:
- A. teach skills to recognize and respond to health threatening situations
- B. increase the client’s awareness of unsatisfactory protective behaviors
- C. implement behavior modification
- D. promote homeostasis and minimize the client’s withdrawal symptoms
Correct answer: A
Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
3. What ECG changes are seen in hypokalemia?
- A. Flattened T waves on the ECG
- B. Elevated ST segments on the ECG
- C. Widened QRS complex
- D. Prominent U waves on the ECG
Correct answer: A
Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.
4. Understanding the causes of mental disorders is important because ________
- A. effective treatment is not possible without such an understanding.
- B. classification of disorders cannot be done without such information.
- C. such knowledge might make both the prevention and cure of mental disorders possible.
- D. disagreements about the causes of psychopathology have long limited the advancements made in the study of abnormal psychology.
Correct answer: C
Rationale: Understanding the causes of mental disorders is crucial because it can potentially lead to both prevention and cure. By identifying the root causes, strategies can be developed to prevent the onset of disorders, and effective treatments can be tailored to address these causes directly. This approach can make treatments more efficient, as addressing the underlying factors contributing to the disorder can result in better outcomes for individuals. Choices A and B are incorrect because while understanding causes is important for effective treatment and classification, the primary focus is on prevention and cure. Choice D, while highlighting the impact of disagreements on advancements in abnormal psychology, does not directly address the importance of understanding causes for prevention and cure.
5. Two-year-old Eva's parents meet her assertions of independence with tolerance and understanding. They provide suitable guidance and reassurance. According to Erikson's theory, Eva will develop __________ as a result.
- A. basic trust
- B. mistrust
- C. autonomy
- D. industry
Correct answer: C
Rationale: According to Erikson's theory of psychosocial development, when parents support a child's growing independence with guidance and reassurance, the child develops a sense of autonomy. Autonomy is characterized by a growing sense of self-control, confidence, and independence. Basic trust (choice A) is associated with the first stage of Erikson's theory (trust vs. mistrust) during infancy. Mistrust (choice B) arises when a child's basic needs are not met consistently, leading to a lack of trust in the world. Industry (choice D) is related to Erikson's later stages of development and involves competence and productivity in work and tasks.
