Which of the following should never be performed by a healthcare professional?

  • A. Heimlich maneuver
  • B. Euthanasia
  • C. Assessment
  • D. Palliative care
Correct Answer: B

Rationale: Euthanasia involves intentionally ending a patient's life to relieve suffering, which is ethically and legally prohibited in most healthcare settings. Healthcare professionals are bound by codes of ethics to prioritize patient well-being, comfort, and dignity, making euthanasia incompatible with their professional responsibilities. Performing euthanasia can have serious legal and ethical consequences for healthcare providers, including loss of licensure and potential criminal charges. Therefore, healthcare professionals should not engage in euthanasia practices.

What are the functional units of the kidney?

  • A. Ureters
  • B. Glomeruli
  • C. Nephrons
  • D. Renal capsules
Correct Answer: C

Rationale: Nephrons are the functional units of the kidney responsible for filtering blood, regulating fluid balance, and forming urine. Each kidney contains thousands of nephrons that work together to maintain homeostasis in the body. Ureters are tubes that carry urine from the kidneys to the bladder, not the functional units. Glomeruli are part of the nephron structure, specifically involved in the initial filtration of blood. Renal capsules are outer coverings of the kidney and do not serve as the functional units responsible for kidney function.

When drawing blood from the antecubital region, which vessel is used?

  • A. Radial artery.
  • B. Brachial Vein
  • C. Ulnar Vein
  • D. Axillary artery
Correct Answer: B

Rationale:

What contributes to phagocytosis in white blood cells?

  • A. Golgi apparatus.
  • B. Endoplasmic reticulum.
  • C. Vacuoles.
  • D. Lysosomes.
Correct Answer: D

Rationale:

What is the function of thrombocytes?

  • A. Blood clotting
  • B. Oxygen transport
  • C. Immune response
  • D. Hormone production
Correct Answer: A

Rationale: Thrombocytes, also known as platelets, play a crucial role in blood clotting. When there is an injury or damage to a blood vessel, thrombocytes adhere to the site and form a plug to stop bleeding. This process is essential for wound healing and preventing excessive blood loss. Therefore, the correct function of thrombocytes is blood clotting.

Which cavity of the heart has the thickest wall?

  • A. Right atrium
  • B. Left atrium
  • C. Right ventricle
  • D. Left ventricle
Correct Answer: D

Rationale: The correct answer is the left ventricle. The left ventricle has the thickest wall among the heart cavities as it needs to pump oxygenated blood to the entire body, requiring more force and muscle strength. Its thick wall helps generate enough pressure to propel blood through the systemic circulation. The other choices, including the right atrium, left atrium, and right ventricle, do not have as thick walls as the left ventricle because their functions involve receiving and transferring blood with lower pressure requirements.
