ATI TEAS 7
Anatomy
1. Pseudostratified columnar epithelium
- A. Skeletal muscle
- B. Bony skeleton
- C. External ears
- D. Bloodstream
Correct answer: C
Rationale: The correct answer is C: External ears. Pseudostratified columnar epithelium is a type of epithelial tissue found in the respiratory tract, where it appears to be stratified but all cells are anchored to the basement membrane. The external ears are lined with pseudostratified columnar epithelium to help protect and support the structures of the ear canal. Skeletal muscle (A) is a type of muscle tissue, bony skeleton (B) refers to bones, and bloodstream (D) is a system for blood circulation, which are not related to pseudostratified columnar epithelium.
2. What type of sentence is the following: "Wow, what a beautiful sunset!"
- A. Interrogative sentence
- B. Declarative sentence
- C. Exclamatory sentence
- D. Imperative sentence
Correct answer: C
Rationale: The sentence expresses an emotion ("Wow") and makes an exclamation, making it an exclamatory sentence.
3. What is the main topic of the passage?
- A. Benefits of bioremediation in cleaning oil spills.
- B. Dangers of microplastics to marine ecosystems.
- C. History of plastic production and its global impact.
- D. Comparison of different waste management strategies.
Correct answer: B
Rationale: The passage focuses on the specific issue of microplastics in the marine environment and their harmful effects.
4. Damage to which part of the brain can lead to difficulty with language and speech?
- A. Broca's area
- B. Wernicke's area
- C. Occipital lobe
- D. Cerebellum
Correct answer: A
Rationale: The correct answer is A: Broca's area. Broca's area, located in the frontal lobe of the brain, is crucial for language production. Damage to Broca's area can result in expressive aphasia, where individuals have difficulty speaking fluently and forming coherent sentences. Wernicke's area, located in the temporal lobe, is responsible for understanding and interpreting language. Damage to Wernicke's area can lead to receptive aphasia, where individuals have difficulty understanding language. The occipital lobe is primarily responsible for processing visual information, while the cerebellum is involved in motor coordination and balance, not language and speech.
5. A lab test result shows a blood glucose level of 5.5 millimoles per liter (mmol/L). What is the equivalent level in milligrams per deciliter (mg/dL)?
- A. 55 mg/dL
- B. 5.5 mg/dL
- C. 0.55 mg/dL
- D. 550 mg/dL
Correct answer: A
Rationale: This requires a double conversion: millimoles to milligrams and liters to deciliters. 1 millimole is equal to 180.15 milligrams, and 1 liter is equal to 10 deciliters. Multiply the glucose level (5.5 mmol/L) by the conversion factor for millimoles to milligrams (180.15 mg/mmol) and then divide by the conversion factor for liters to deciliters (10 dL/L): 5.5 mmol/L * 180.15 mg/mmol / 10 dL/L ≈ 55 mg/dL.
6. The bones of the skull are classified as what type of bone?
- A. Long bone
- B. Short bone
- C. Flat bone
- D. Irregular bone
Correct answer: C
Rationale: The correct answer is C: Flat bone. The bones of the skull are classified as flat bones due to their thin, flattened shape. Flat bones provide protection to vital organs and have a broad surface for muscle attachment. Long bones, like the femur, are characterized by their elongated shape, while short bones, such as those in the wrist and ankle, are cube-shaped. Irregular bones have complex shapes and do not fit into the other bone categories. In this case, the flat bones of the skull best fit the classification.
