Which of the following is a core component of the definition of Metabolic Syndrome?
- A Elevated HDL cholesterol only
- B Visceral (abdominal) obesity
- C High fasting insulin with normal glucose as sole criterion
- D Autoimmune destruction of pancreatic β-cells
Correct answer: Visceral (abdominal) obesity
Metabolic syndrome is characterised by several metabolic abnormalities, and central (visceral) obesity is one of the key features.
Insulin resistance is best described as:
- A Cells responding excessively to insulin leading to hypoglycaemia
- B Cells failing to respond properly to insulin despite normal or high levels
- C The complete absence of insulin production by the pancreas
- D A condition only seen in type 1 diabetes
Correct answer: Cells failing to respond properly to insulin despite normal or high levels
Insulin resistance occurs when muscle, fat and liver cells do not respond adequately to insulin, so more insulin is required to effect glucose uptake.
According to common clinical criteria, a person may be diagnosed with metabolic syndrome when they have:
- A All five defined risk factors must be present simultaneously
- B At least three of the defined cardiometabolic risk factors
- C Only an elevated fasting glucose with no other abnormality
- D Only central obesity without any other metabolic abnormality
Correct answer: At least three of the defined cardiometabolic risk factors
Many guidelines state that metabolic syndrome is present if three or more risk factors from the defined list are met.
Which of the following risk factors is most strongly associated with the development of insulin resistance?
- A Consistently high HDL cholesterol levels
- B Sedentary lifestyle with abdominal obesity
- C Young chronological age and female sex
- D Persistently low fasting triglyceride levels
Correct answer: Sedentary lifestyle with abdominal obesity
A sedentary lifestyle and increased abdominal fat (visceral adiposity) impair insulin action and are major contributors to insulin resistance.
In patients with insulin resistance, the pancreas often responds initially by:
- A Reducing its insulin output in order to conserve cellular energy
- B Producing more insulin (hyperinsulinaemia) to keep glucose normal
- C Shutting down completely and producing no further insulin at all
- D Secreting only glucagon in place of any pancreatic insulin output
Correct answer: Producing more insulin (hyperinsulinaemia) to keep glucose normal
In early insulin resistance the pancreas compensates by producing more insulin to maintain glucose homeostasis; over time this compensation may fail.
Which lipid abnormality is typically part of metabolic syndrome?
- A Low triglycerides and high HDL
- B High triglycerides and low HDL cholesterol
- C High HDL only with normal triglycerides
- D Only elevated LDL is required
Correct answer: High triglycerides and low HDL cholesterol
Atherogenic dyslipidaemia in metabolic syndrome often includes elevated triglycerides and reduced HDL cholesterol.
A nurse is assessing a patient for metabolic syndrome. Which blood pressure reading would align with one of the criteria?
- A 120/70 mmHg
- B 128/82 mmHg
- C 110/60 mmHg
- D 100/70 mmHg
Correct answer: 128/82 mmHg
Elevated blood pressure (for example ≥130/85 mmHg or being treated for hypertension) is one of the criteria for metabolic syndrome.
Why is visceral obesity (abdominal fat) particularly important in the pathophysiology of insulin resistance?
- A Subcutaneous fat is far more metabolically active than visceral fat
- B It releases free fatty acids and cytokines that impair insulin signalling
- C Only subcutaneous fat, not visceral fat, drives insulin resistance
- D Visceral fat has essentially no relationship to overall metabolic risk
Correct answer: It releases free fatty acids and cytokines that impair insulin signalling
Visceral adipose tissue releases fatty acids and inflammatory mediators that interfere with insulin signalling in muscle, liver and adipose tissue.
Which of the following statements about insulin resistance and type 2 diabetes is correct?
- A Insulin resistance, when present, always progresses to type 1 diabetes
- B It precedes type 2 diabetes once pancreatic beta-cells fail to compensate
- C Insulin resistance only develops after diabetes is already established
- D Insulin resistance is fixed and cannot be improved by any intervention
Correct answer: It precedes type 2 diabetes once pancreatic beta-cells fail to compensate
Insulin resistance can precede type 2 diabetes; if the pancreas cannot maintain elevated insulin production, hyperglycaemia develops.
Which of the following lifestyle interventions is MOST effective for improving insulin sensitivity in metabolic syndrome?
- A Increasing intake of processed, refined carbohydrate foods
- B Weight loss, increased physical activity and dietary improvement
- C Relying on medication alone with no accompanying lifestyle change
- D Reducing dietary salt intake without any other modifications
Correct answer: Weight loss, increased physical activity and dietary improvement
Lifestyle measures such as weight reduction, regular exercise and improved diet are foundational in reversing insulin resistance and managing metabolic syndrome.
A man has a waist circumference of 105 cm, triglycerides of 160 mg/dL, HDL cholesterol of 38 mg/dL, blood pressure 135/90 mmHg and fasting glucose 102 mg/dL. Does he meet criteria for metabolic syndrome?
- A Yes, because he has at least three of the criteria
- B No, because fasting glucose is too low
- C No, because HDL is not below 30 mg/dL
- D Yes, only if he also has high LDL cholesterol
Correct answer: Yes, because he has at least three of the criteria
He meets at least three criteria (waist, TG, HDL, BP, glucose) so he qualifies for metabolic syndrome.
In insulin resistance, which of the following lab signs may appear early?
- A Low insulin with normal glucose
- B Normal insulin, normal glucose forever
- C Elevated fasting insulin with normal glucose
- D Very low fasting insulin and high glucose immediately
Correct answer: Elevated fasting insulin with normal glucose
In early insulin resistance hyperinsulinaemia may maintain normal glucose levels even though insulin sensitivity is poor.
Which hormone typically rises in insulin resistance and contributes to further metabolic dysfunction?
- A Adiponectin, which improves insulin sensitivity
- B Leptin, with rising free fatty acids
- C Thyroid-stimulating hormone, driving the metabolism
- D Glucagon, suppressed by the high insulin levels
Correct answer: Leptin, with rising free fatty acids
In insulin resistance, adipose hormones such as leptin (with leptin resistance) and free fatty acids rise and impair insulin signalling; adiponectin, which enhances insulin sensitivity, is typically reduced.
A patient with metabolic syndrome asks what their risk is of developing type 2 diabetes compared with someone without the syndrome. The nurse replies:
- A The risk remains essentially unchanged
- B The risk is somewhat lower than average
- C The risk is significantly increased
- D The risk falls to zero with good diet
Correct answer: The risk is significantly increased
Metabolic syndrome is associated with a markedly increased risk of type 2 diabetes and cardiovascular disease.
Which of the following is a distinguishing feature of insulin resistance but not necessarily of metabolic syndrome?
- A Hypertension on repeated readings
- B Persistently high triglyceride levels
- C Elevated fasting insulin level
- D Reduced HDL cholesterol concentration
Correct answer: Elevated fasting insulin level
Insulin resistance (e.g., elevated fasting insulin) underlies metabolic syndrome but is distinct from its diagnostic criteria; hypertension, high triglycerides and low HDL are among those criteria.
Which of the following signs may appear in overweight adolescents and indicate early metabolic syndrome?
- A Normal waist, normal lipids, and normal insulin response
- B Increased waist, elevated triglycerides, and high blood pressure
- C Low HDL cholesterol with no other associated features
- D High LDL cholesterol with no other associated features
Correct answer: Increased waist, elevated triglycerides, and high blood pressure
Even in adolescents, the clustering of central obesity, elevated lipids and hypertension signals early metabolic syndrome risk.
A primary nursing teaching point for a patient with insulin resistance is:
- A The condition cannot be changed, so rely only on medication
- B Lifestyle change can improve insulin sensitivity and slow progression
- C Only metabolic syndrome, not insulin resistance, causes heart disease
- D Insulin resistance affects only sugar, not lipids or blood pressure
Correct answer: Lifestyle change can improve insulin sensitivity and slow progression
Educating the patient that lifestyle choices (diet, exercise, weight) can improve insulin sensitivity is vital in management.
Which of the following is a mechanism by which insulin resistance contributes to hypertension in metabolic syndrome?
- A Decreased sympathetic nervous system activity
- B Enhanced endothelial nitric oxide production
- C Renal sodium retention and increased vascular tone
- D Total absence of insulin receptors within the kidneys
Correct answer: Renal sodium retention and increased vascular tone
Insulin resistance and hyperinsulinemia may promote sodium retention and increased sympathetic/vascular tone thereby raising blood pressure.
When evaluating a patient for metabolic syndrome, measuring which waist circumference (WC) would indicate a high risk (for example, in women)?
- A 80 cm
- B 88 cm or more
- C 70 cm or less
- D 95 cm or less
Correct answer: 88 cm or more
A WC of ≧88 cm in women (or ≧102 cm in men) is commonly used as a cut-point for abdominal obesity in metabolic syndrome criteria.
A patient with confirmed metabolic syndrome asks about pharmacologic therapy specifically for insulin resistance. Which statement is correct?
- A There are many medications approved solely to treat insulin resistance in metabolic syndrome
- B Pharmacologic therapy may target components (e.g., dyslipidaemia, hypertension, hyperglycaemia) but lifestyle remains foundational
- C Medication can replace the need for physical activity entirely
- D Only insulin therapy is used for metabolic syndrome
Correct answer: Pharmacologic therapy may target components (e.g., dyslipidaemia, hypertension, hyperglycaemia) but lifestyle remains foundational
While there are no drugs approved purely for insulin resistance per se, many medications treat the syndrome’s components (e.g., metformin, statins), but lifestyle intervention remains central.
