Which of the following statements regarding dietary approaches to obesity treatment is TRUE?
- A. Dietary approaches are not as important as pharmacological approaches
- B. Carbohydrates have a greater satiating effect compared with proteins and fats, especially in individuals with prediabetes and obesity
- C. Intermittent fasting has consistently shown superior weight loss to very-low calorie and ketogenic diets as it is the easiest to adhere to
- D. Patient preference of dietary interventions plays a key part in adherence and ultimately weight loss and maintenance
Correct Answer: D
Rationale: Dietary approaches to obesity vary, but patient preference significantly influences adherence and long-term weight loss success, per behavioral studies making this true. Pharmacological approaches complement, not overshadow, diet. Proteins/fats are more satiating than carbohydrates, especially in prediabetes/obesity. Intermittent fasting's superiority isn't consistent adherence varies, not universally easier than ketogenic or very-low calorie diets. Preference drives sustainability, key for physicians tailoring chronic obesity interventions.

Which is not a differential diagnosis for tetanus?
- A. strychnine poisoning
- B. dystonic reactions
- C. quinsy
- D. rabies
Correct Answer: C
Rationale: Tetanus mimics strychnine, dystonia, rabies flex muscles; cyanide gasps, quinsy's throat, not spasms. Nurses sift this chronic stiffness list.
The physician tells the patient that there will be an initial course of treatment with continued maintenance treatments and ongoing observation for signs and symptoms over a prolonged period of time. You can help the patient by reinforcing that the primary goal for this type of treatment is:
- A. Cure
- B. Control
- C. Palliation
- D. Permanent remission
Correct Answer: B
Rationale: The physician's plan initial treatment, maintenance, and long-term monitoring suggests a chronic cancer unamenable to cure, aiming instead to control growth and spread. Control stabilizes disease, extending life and quality, unlike cure, which eradicates cancer, or permanent remission, implying no recurrence both unfeasible here. Palliation focuses on symptom relief, not longevity, misaligning with ongoing treatments. Reinforcing control clarifies expectations, reducing anxiety by framing therapy as proactive management, not defeat. Nurses bolster this by explaining observation's role in adjusting care, aligning patient understanding with realistic goals, vital for adherence and emotional resilience in prolonged cancer battles.
On a population level, differences can be observed between the body composition of people with and people without a disturbed glucose tolerance. Question: Which of the following options describes the body composition of overweight people with a disturbed glucose tolerance compared to that of healthy people without overweight?
- A. More adipose tissue and similar muscle mass
- B. More adipose tissue and less muscle mass
- C. More adipose tissue and more muscle mass
- D. More adipose tissue and less muscle mass, including a change in the ratio of different types of muscle fibres
Correct Answer: B
Rationale: Glucose tolerance tanks overweight pile fat, lose muscle, not same or more, no fibre shift specifics. Nurses see this, a chronic lean loss.
Which statement about carcinogenesis is accurate?
- A. An initiated cell will always become clinical cancer.
- B. Cancer becomes a health problem once it is 1 cm in size.
- C. Normal hormones and proteins do not promote cancer growth.
- D. Tumor cells need to develop their own blood supply.
Correct Answer: D
Rationale: Carcinogenesis is the multi-step process by which normal cells transform into cancer cells, involving initiation, promotion, and progression. A key aspect of this process is angiogenesis, where tumor cells induce the formation of new blood vessels to supply nutrients and oxygen, enabling their growth beyond a minimal size. This is a critical step, as without a blood supply, tumors cannot sustain themselves or expand significantly. The statement that an initiated cell always becomes cancer is inaccurate because initiation alone is not sufficient; it requires promoters to progress. Similarly, the idea that cancer only becomes a problem at 1 cm oversimplifies the issue tumors can pose health risks earlier depending on location and type, though 1 cm is a detectable size. Normal hormones and proteins, like estrogen or growth factors, can indeed act as promoters in carcinogenesis, contradicting that option. Thus, the need for a tumor to develop its own blood supply is the most accurate statement, reflecting a fundamental biological requirement for cancer progression, which nurses must recognize when caring for oncology patients.
During a routine health examination, a 40-yr-old patient tells the nurse about a family history of colon cancer. Which action should the nurse take next?
- A. Obtain more information about the family history.
- B. Schedule a sigmoidoscopy to provide baseline data.
- C. Teach the patient about the need for a colonoscopy at age 50.
- D. Teach the patient how to do home testing for fecal occult blood.
Correct Answer: A
Rationale: Family history of colon cancer flags risk first step's digging deeper: who, when, how many cases? That shapes if it's sporadic or hereditary (e.g., Lynch syndrome), guiding screening timing. Jumping to sigmoidoscopy or fecal tests skips assessment too soon without details. Colonoscopy at 50's standard, but family history might bump it earlier (e.g., 40 or 10 years before kin's diagnosis). Nurses in oncology start here, gathering intel to tailor prevention, not rushing tools that might miss the mark without context.
