Weekend Trivia Round-Up: Answers & Explanations for This Week’s Diabetes Trivia!
Welcome to the first in a series of posts where we dive into the answers to the daily trivia questions. We’ll break down each question starting from Friday and work our way up to Monday. Ready? Let's Go!
Friday Trivia
Question: A patient with diabetes asks how often to check HbA1c. For stable control, how often is it generally recommended?
Options:
A) Monthly
B) Every 3 months
C) Every 6 months
D) Annually
Answer: B) Every 3 months
Explanation:
HbA1c, also known as glycated hemoglobin, is a type of hemoglobin (the protein in our red blood cells that carries oxygen) that has glucose stuck to it. Imagine it as a red blood cell “sugar report” that gives us an idea of blood sugar levels over the past few months. Here’s how it works and why it’s such a valuable indicator for people managing diabetes.
Whenever there’s glucose (sugar) in the blood, some of it binds to hemoglobin, forming HbA1c. This bonding process is called glycation. It’s a steady, non-reversible process, which means once glucose attaches to hemoglobin, it stays there for the cell’s lifespan—roughly about three months. That’s why HbA1c gives a “big picture” of blood sugar levels over the past 8-12 weeks.
When doctors measure HbA1c, they’re looking at the percentage of hemoglobin with glucose attached. The higher your blood sugar levels have been, the higher the HbA1c percentage. This makes it an excellent way to see how well blood sugar has been managed over time—not just at one specific moment (which can fluctuate day by day).
Thursday Trivia
Question: A patient with diabetes presents with swollen ankles and proteinuria. Which test is essential to assess this?
Options:
A) HbA1c
B) eGFR
C) Random glucose
D) Liver function test
Answer: B) eGFR
Explanation:
Swollen ankles and proteinuria (the presence of protein in the urine) are signs that may suggest kidney involvement in diabetes. The estimated Glomerular Filtration Rate (eGFR) test measures kidney function by estimating how well blood is filtered through the kidneys. Kidney complications, including diabetic nephropathy, are common in diabetes. Early detection through tests like eGFR and urine microalbumin can lead to better management and prevention of further kidney damage.
Wednesday Trivia
Question: A patient with diabetes has darkened skin patches on their neck. This may be due to:
Options:
A) Neuropathy
B) Insulin resistance
C) Sun exposure
D) Vitamin deficiency
Answer: B) Insulin resistance
Explanation:
Darkened skin patches, especially on the neck, underarms, or groin, may be a sign of acanthosis nigricans. This condition is often linked with insulin resistance—a key underlying factor in type 2 diabetes. Insulin resistance occurs when cells don’t respond effectively to insulin, leading to higher insulin levels in the bloodstream. Over time, this can cause darkening and thickening of the skin, particularly in body folds. Acanthosis nigricans is a common indicator that may prompt further screening for diabetes or pre-diabetes.
Tuesday Trivia
Question: A patient with type 1 diabetes shows tremors, sweating, and confusion. What’s the best immediate action?
Options:
A) Inject insulin
B) Take metformin
C) Consume glucose
D) Drink water
Answer: C) Consume glucose
Explanation:
These symptoms—tremors, sweating, and confusion—are classic signs of hypoglycemia (low blood sugar). In this state, the brain doesn’t receive enough glucose to function properly, which can quickly become life-threatening. The immediate treatment for hypoglycemia is to consume a source of fast-acting glucose, such as glucose tablets or a sugary drink. It’s vital to act swiftly to prevent worsening symptoms. Once blood sugar stabilizes, it’s good practice to eat a balanced snack to prevent a rebound low.
Monday Trivia
Question: A boy was rushed to the hospital because he suddenly fainted. He was noted to have sweet-smelling breath and was passing little or no urine. What's the likely diagnosis?
Options:
A) Acute kidney injury
B) Cancer
C) Diabetes
D) Gout
Answer: C) Diabetes
Explanation:
This scenario describes the classic presentation of diabetic ketoacidosis (DKA), a serious complication often seen in type 1 diabetes. When the body can’t use glucose for energy due to a lack of insulin, it breaks down fat instead, leading to the production of ketones. High levels of ketones can cause the blood to become acidic, resulting in the symptoms of fruity or sweet-smelling breath, dehydration, and reduced urine output. DKA is a medical emergency and requires prompt treatment.
