Question 1
Multiple Choice
Which of the following components should not be present in normal urinalysis results?
Correct!
Incorrect
The correct answer is: A,B,D,E,F
Rationale
Glucose should not be present in normal urinalysis results. Elevated glucose levels indicate potential underlying health issues such as diabetes mellitus, making its presence in urine abnormal and concerning for health professionals.
C: 0 to 5 WBCs Normal urine may contain a small number of white blood cells, indicating no significant inflammation or infection, thus this finding is acceptable in urinalysis.

Question 2

The bilirubin level is used to evaluate the function of the
Correct!
Incorrect
The correct answer is: B
Rationale
The bilirubin level is used to evaluate the function of the liver. Elevated bilirubin indicates liver dysfunction, as the liver processes and excretes bilirubin; thus, measuring its levels provides crucial insights into liver health and possible diseases.
A: Pancreas Bilirubin levels do not reflect pancreatic function, which is primarily assessed through enzymes related to digestion and metabolic processes rather than bilirubin metabolism.
C: Spleen The spleen primarily filters blood and produces immune responses; it does not play a significant role in bilirubin processing, which is mainly a liver function.
D: Kidneys Kidney function is evaluated through different parameters such as creatinine and urea levels, not bilirubin, which is specifically associated with liver health and function.

Question 3
Multiple Choice
Before performance of a computed tomography (CT) scan, it is vital to assess which of the following?
Correct!
Incorrect
The correct answer is: B,C
Rationale
Before a computed tomography (CT) scan, it is vital to assess allergy to iodine. Iodine-based contrast agents are commonly used in CT imaging, and allergic reactions can pose serious health risks during the procedure.
A: Allergy to eggs. Egg allergies are not typically relevant to CT scans, as the primary concern lies with iodine-based contrast agents, not egg proteins.
C: Allergy to shellfish. While some individuals with shellfish allergies may have iodine sensitivity, this does not universally apply, and iodine specifically needs assessment before CT scans.
D: Allergy to gluten. Gluten allergies are unrelated to the use of contrast media in CT scans, as gluten does not impact the safety or effectiveness of imaging procedures.

Question 4
Regular
Before having CT dye, you should also assess for which of the following?
Correct!
Incorrect
The correct answer is: D
Rationale
Impaired renal function should be assessed before having CT dye. This is crucial as contrast agents can be nephrotoxic, particularly in individuals with pre-existing kidney issues, potentially leading to acute kidney injury.
A: Wide pulse pressure indicates cardiovascular issues and is not directly related to the administration of CT dye, which primarily concerns renal safety and contrast reactions.
B: Atelectasis refers to lung collapse and does not pertain to the assessment of kidney function or the impact of CT dye on renal health.
C: Elevated white blood cell count suggests infection or inflammation, which does not directly influence the safety or necessity of assessing renal function prior to CT dye usage.
