Explanation:

• For Question 3: The normal pH range of human blood is 7.35 - 7.45. This is due to the body's buffering systems that maintain blood's acid - base balance.
• For Question 4: Both hyperkalemia (high potassium levels) and hypokalemia (low potassium levels) can disrupt the normal electrical activity of the heart, leading to cardiac arrhythmias.
• For Question 5: While symptoms can suggest a UTI, urinalysis and bacterial culture are often required for accurate diagnosis and appropriate therapy to identify the causative organism and its antibiotic susceptibility.
