What are the potential adverse effects of diuretic therapy in neonates?

  1. Hypokalemia

  2. Hyponatremia

  3. Metabolic alkalosis

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Diuretic therapy in neonates can lead to potential adverse effects, including hypokalemia, hyponatremia, and metabolic alkalosis. Hypokalemia is a condition characterized by low potassium levels in the blood, hyponatremia is a condition characterized by low sodium levels in the blood, and metabolic alkalosis is a condition characterized by an increase in blood pH and bicarbonate levels.

Multiple choice

What is the primary role of chondrocytes in cartilage tissue?

  1. They produce and maintain the extracellular matrix

  2. They provide structural support to the cartilage tissue

  3. They regulate the metabolism of cartilage tissue

  4. They facilitate the movement of nutrients and waste products
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Chondrocytes are specialized cells found in cartilage tissue. Their primary role is to produce and maintain the extracellular matrix, which consists of collagen, proteoglycans, and other components. The extracellular matrix provides structural support and resilience to cartilage tissue.
