Practice Math TEAS TEST

1. If a box of 55 syringes costs $660.00, what is the cost of four syringes?

A. $51.00
B. $26.00
C. $32.00
D. $48.00

Correct answer: D

Rationale: To find the cost of one syringe, divide the total cost by the number of syringes: $660.00 Ã· 55 = $12. Therefore, the cost of four syringes is 4 x $12 = $48. Choices A, B, and C are incorrect because they do not correctly calculate the cost per syringe or the total cost of four syringes.

2. To whom is this passage probably being written?

A. a mother
B. a father
C. a babysitter
D. a nurse

Correct answer: C

Rationale: The passage provides detailed instructions on how to take care of a little girl, indicating that the intended audience is someone other than the child's parents. A babysitter is the most likely recipient of these instructions, as they are typically hired to care for children when the parents are away. The specific guidance on feeding, naptime routine, and other care tasks align with what a babysitter would need to know to care for a child in place of the parents. Choices A, B, and D are incorrect because the passage does not address the child's parents directly. It focuses on providing guidance to someone temporarily responsible for the child's care, such as a babysitter.

3. Diabetic nephropathy, a complication of diabetes, affects the:

A. Ureters
B. Bladder
C. Urethra
D. Nephrons

Correct answer: D

Rationale: Diabetic nephropathy, a complication of diabetes, affects the nephrons. Nephrons are the functional units of the kidneys responsible for filtering blood and producing urine. The high blood sugar levels associated with diabetes can damage the nephrons over time, leading to kidney dysfunction and, ultimately, kidney failure. Choices A, B, and C are incorrect because diabetic nephropathy primarily impacts the nephrons in the kidneys, not the ureters, bladder, or urethra.

4. Adaptive radiation refers to the evolutionary process where:

A. A single ancestral species diversifies into multiple descendant species due to ecological pressures in a heterogeneous environment.
B. Two unrelated species evolve similar adaptations in response to similar environments, leading to convergent evolution.
C. A population becomes increasingly well-adapted to its current environment through continued natural selection.
D. The fossil record exhibits gaps or missing links in the evolutionary history of a lineage.

Correct answer: A

Rationale: - Adaptive radiation is a process where a single ancestral species diversifies into multiple descendant species to exploit different ecological niches within a heterogeneous environment. - This diversification occurs due to the different selective pressures present in various habitats, leading to the evolution of distinct traits and adaptations in different descendant species. - Option A accurately describes the process of adaptive radiation, where the initial species undergoes rapid speciation to occupy different ecological roles and adapt to diverse environmental conditions. - Options B, C, and D do not accurately describe adaptive radiation but refer to other evolutionary processes such as convergent evolution, natural selection, and gaps in the fossil record, respectively.

5. Which structure protects the lungs?

A. Femur
B. Ribcage
C. Scapula
D. Skull

Correct answer: B

Rationale: The ribcage is the correct answer. It protects the lungs by providing structural support and shielding them from injury. The femur is a bone in the thigh and does not protect the lungs. The scapula is a shoulder blade bone, and the skull protects the brain, not the lungs.
