Which of these is not a reason for hypoglycemia?

Appeared in: NHM MP Staff Nurse-2019

Explanation

  • Physical activity increases glucose uptake by the muscles for energy, which lowers blood sugar levels.
  • Consequently, a reduction in physical activity leads to decreased glucose utilization.
  • This decreased use of glucose tends to raise blood sugar levels (hyperglycemia) or keep them stable, rather than causing them to drop.
  • Therefore, less physical activity is a risk factor for hyperglycemia, not hypoglycemia, making it the correct answer.

Why Other Options Were Wrong

  • Option A: Skipping or delaying meals directly reduces the body's incoming supply of glucose from carbohydrates, which is a very common cause of hypoglycemia, especially in individuals on diabetes medication.
  • Option C: Insulin's primary function is to lower blood glucose. An overdose of insulin will drive an excessive amount of glucose into the cells, leading to a sharp and dangerous drop in blood sugar levels (iatrogenic hypoglycemia).
  • Option D: Certain classes of oral anti-diabetic drugs, such as sulfonylureas and meglitinides, work by stimulating the pancreas to release more insulin. This action can lead to hypoglycemia as a known side effect.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Causes and risk factors for hypoglycemia as background academic context rather than a clinical decision trigger.
  • Patient education is a critical nursing responsibility. Nurses must teach patients with diabetes how to balance medication, diet, and physical activity to prevent both hypoglycemia and hyperglycemia.
  • Rapid recognition and treatment of hypoglycemia are essential to prevent severe outcomes like seizures, coma, and death. The 'Rule of 15' is a key intervention.
  • What if? If the question stated the patient engaged in more physical activity than usual without adjusting their food or insulin, this would become a primary reason for hypoglycemia.
How to Approach the Question
  • First, identify the core concept being tested, which is hypoglycemia (low blood sugar).
  • Pay close attention to the negative keyword 'NOT'. The question is asking you to find the option that does NOT cause low blood sugar.
  • Analyze each option's physiological effect on blood glucose levels.
  • For 'Skipping a meal', think: Less food means less sugar intake, which lowers blood glucose. This is a cause.
  • For 'Less physical activity', think: Activity uses up sugar. Less activity means less sugar is used, which would raise, not lower, blood glucose. This is NOT a cause.
  • For 'More insulin', think: Insulin's job is to lower blood sugar. More insulin means a bigger drop. This is a cause.
Concept Tested & Keywords
  • Concept Tested: Causes and risk factors for hypoglycemia.
  • Stem keywords: hypoglycemia, reason
  • Lead-in keywords: not
  • Negative lead-in flag: This question uses negative framing ('NOT'), asking you to identify the option that is an exception.
