1. An elderly man is hospitalized with a diagnosis of malnutrition three months following his wife's death. What risk factor for malnutrition does this scenario illustrate?
- A. A history of chronic illness
- B. Depression or social isolation
- C. Age
- D. Impaired mobility
Correct answer: B
Rationale: This scenario illustrates depression or social isolation as a risk factor for malnutrition. After the death of his wife, the elderly man may have experienced depression or social isolation, which can lead to decreased food intake and poor nutritional status. Although age, chronic illness, and impaired mobility can also contribute to malnutrition, they are not the primary factors described in this scenario. The history of chronic illness (Choice A) and impaired mobility (Choice D) were not mentioned in the scenario, and while age (Choice C) is a factor, it's not the main factor depicted in this case.
2. Theorists who emphasize plasticity believe that __________.
- A. change in response to influential experiences is possible
- B. heredity, rather than the environment, influences behavior
- C. individuals who are high in anxiety as children will remain so at later ages
- D. early experiences establish a lifelong pattern of behavior
Correct answer: A
Rationale: Theorists who emphasize plasticity believe that change in response to influential experiences is possible. They argue that individuals have the capacity to adapt and change their behavior based on their experiences, rather than being limited by genetic predispositions or early childhood experiences. This perspective highlights the importance of environmental influences in shaping behavior and development. Choices B, C, and D are incorrect because they do not align with the concept of plasticity, which emphasizes the flexibility and adaptability of individuals in response to their experiences, rather than being fixed by heredity, childhood traits, or early experiences.
3. Amy is a 68-year-old patient who has rheumatoid arthritis affecting her hands and feet. Which substance has been shown to reduce joint tenderness and improve mobility in some people with this type of arthritis?
- A. Alfalfa Tea
- B. Cod Liver Oil
- C. Lecithin
- D. Fish Oil
Correct answer: Fish Oil
Rationale: Fish oil has been identified as a substance that can help reduce joint tenderness and improve mobility in individuals with rheumatoid arthritis, as it is rich in omega-3 fatty acids. Omega-3 fatty acids have anti-inflammatory properties that can help alleviate the symptoms of rheumatoid arthritis. On the other hand, while Alfalfa Tea, Cod Liver Oil, and Lecithin have various health benefits, there isn't substantial evidence to suggest that they can improve conditions associated with rheumatoid arthritis.
4. A nurse is assessing a client who has acute pancreatitis and is at risk for an acid-base imbalance. For which manifestation of this acid-base imbalance should the nurse assess?
- A. Agitation
- B. Kussmaul respirations
- C. Seizures
- D. Positive Chvosteks sign
Correct answer: Kussmaul respirations
Rationale:
5. The nurse is teaching a community class to people with Type 2 diabetes mellitus. Which explanation would explain the development of Type 2 diabetes?
- A. The islet cells in the pancreas stop producing insulin
- B. The client eats too many foods that are high in sugar
- C. The pituitary gland does not produce vasopressin
- D. The cells become resistant to the circulating insulin
Correct answer: D
Rationale: The correct answer is D. In Type 2 diabetes, the primary issue is insulin resistance, where cells do not respond effectively to insulin. Choice A is incorrect because in Type 1 diabetes, the islet cells in the pancreas stop producing insulin. Choice B is not directly related to the development of Type 2 diabetes but rather to its management. Choice C is incorrect as it refers to a dysfunction in vasopressin production, which is not related to Type 2 diabetes.
