Sample questions from TEAS 7 Complete Study Guide: All Four Sections

This material has 20 questions with answers and rationales. Here are the first 5.

1. 1.Which of the following heart valves prevents the backflow of blood from the left ventricle into the left atrium?

   • A.Aortic valve
   • B.Mitral valve
   • C.Pulmonary valve
   • D.Tricuspid valve

   Rationale: The mitral (or bicuspid) valve is located between the left atrium and the left ventricle. Its function is to prevent blood from flowing backward into the atrium during ventricular systole. The tricuspid is on the right side, the pulmonary valve leads to the lungs, and the aortic valve leads to the aorta.

2. 2.A patient has a blood pH of 7.25. Which of the following conditions is most likely occurring?

   • A.Alkalosis
   • B.Neutrality
   • C.Acidosis
   • D.Hypervolemia

   Rationale: The normal range for blood pH is 7.35 to 7.45. A pH below 7.35 indicates acidosis. Alkalosis occurs when pH is above 7.45. Neutral pH is 7.0, and hypervolemia refers to fluid overload, which is not directly a measure of pH.

3. 3.Which organelle is primarily responsible for the production of ATP within the cell?

   • A.Mitochondria
   • B.Golgi apparatus
   • C.Nucleus
   • D.Ribosome

   Rationale: Mitochondria are known as the powerhouses of the cell because they produce ATP through cellular respiration. The nucleus contains DNA, ribosomes synthesize proteins, and the Golgi apparatus packages proteins for transport.

4. 4.What is the primary function of the large intestine?

   • A.Production of bile
   • B.Absorption of nutrients
   • C.Chemical digestion of proteins
   • D.Reabsorption of water
