Free ATI TEAS Exam Questions That Helps Candidates Pass

TEAS Reading often tests recognition of organizational patterns because text structure guides comprehension. The passage focuses on two entities—Clinic A and Clinic B—highlighting differences in hours (evenings vs. weekends) and culminates in a conclusion about choice criteria. This aligns with a compare-and-contrast structure: presenting similarities/differences and drawing a comparative conclusion. Chronological order (A) arranges events by time and is not indicated. Cause-and-effect (B) requires an explicit causal chain (e.g., “Because Clinic A… therefore patients…”), which the passage does not emphasize; it simply juxtaposes options. Problem-solution (D) would feature a stated issue and a proposed remedy; here, no single problem is framed—only options are evaluated. Recognizing compare-and-contrast helps readers anticipate signal words like “whereas,” “however,” “on the other hand,” and synthesize balanced evaluations. On TEAS, scan for multiple subjects being evaluated along shared criteria; when the author weighs trade-offs and offers a choice recommendation, compare-and-contrast is frequently the best match.

Nonrestrictive clauses add extra information that does not change the core meaning and must be set off by commas. Option C correctly brackets “which was sterile” with commas, leaving a complete sentence when removed (“The syringe remained sealed”). In formal American English, which typically introduces nonrestrictive clauses and that introduces restrictive (essential) clauses without commas; hence D misuses that and adds commas improperly. A omits the necessary commas, making the clause appear restrictive (implying there were multiple syringes and only the sterile one remained sealed), which changes meaning. B places a comma after which, creating a disruptive and ungrammatical pause. On TEAS, determine whether the clause identifies (restrictive) or describes (nonrestrictive). If the sentence still makes sense and retains its main point without the clause, treat it as nonessential and use commas. This rule promotes clarity in clinical documentation: “The catheter, which was inserted at 0900, remains patent” (extra detail) versus “The catheter that occluded was replaced” (identifies which catheter). Consistent punctuation prevents ambiguity about which item or condition your note refers to, reducing risk of misinterpretation.

Use the formula ( \text{gtt/min} = \frac{\text{Volume (mL)} \times \text{Drop factor (gtt/mL)}}{\text{Time (min)}} ). Compute the numerator: (90 \times 15 = 1{,}350\ \text{gtt}). Divide by time: (1{,}350 \div 45 = 30\ \text{gtt/min}). Thus, C is correct. Choice B (24) matches using 60 minutes instead of 45; A (20) results from dividing by 67.5 or using a 10 gtt/mL set; D (32) reflects rounding an incorrect intermediate. On TEAS dosage calculations, keep units explicit and confirm divisibility: (45 \times 30 = 1{,}350) (since (45 \times 3 = 135), append a zero). If the problem instead requested mL/hr, convert 45 minutes to hours (0.75 hr) and compute (90 \div 0.75 = 120\ \text{mL/hr}). Always align the requested unit (gtt/min vs. mL/hr) with the correct formula to avoid mixing drip-factor and pump-rate scenarios.

Align units before computing. Convert mg → mcg because the concentration is in mcg/mL: (0.8\ \text{mg} = 800\ \text{mcg}). Volume needed equals dose divided by concentration:

(\displaystyle \text{mL} = \frac{800\ \text{mcg}}{200\ \text{mcg/mL}} = 4\ \text{mL}).

Thus, C is correct. Option A (2 mL) would provide 400 mcg (underdose). B (3 mL) gives 600 mcg; D (5 mL) gives 1,000 mcg (overdose). On TEAS dosage calculations, always write the conversion first so units cancel cleanly: (0.8\ \text{mg}\times \frac{1{,}000\ \text{mcg}}{1\ \text{mg}} \times \frac{1\ \text{mL}}{200\ \text{mcg}} = 4\ \text{mL}). Sanity check: 800 mcg at 200 mcg per mL is four equal portions—so 4 mL. Also note that if a syringe has maximum markings (e.g., 3 mL), you’d need a larger syringe or two injections; however, the math answer remains 4 mL. Keep micro- vs milli- prefixes straight; a common error is dividing instead of multiplying when converting mg to mcg, which would yield a dangerously small dose.

Metric conversions on TEAS require careful attention to place value. The relationship is 1 mg = 1,000 mcg. To convert mcg → mg, divide by 1,000:

(75\ \text{mcg} \div 1{,}000 = 0.075\ \text{mg}).

Thus, B is correct. Option A (0.0075 mg) divides by 10,000 (one zero too many). Option C (0.75 mg) divides by only 100 (one zero too few). Option D (7.5 mg) is off by a factor of 100; it treats micrograms as milligrams. A reliable strategy is to write the unit equation and set up a fraction that cancels:

(75\ \text{mcg} \times \frac{1\ \text{mg}}{1{,}000\ \text{mcg}} = 0.075\ \text{mg}).

Check reasonableness: since mcg are smaller than mg, the mg value must be smaller than 75, and clearly less than 1. Placing the decimal three places to the left (divide by 1,000) is a fast mental check for micro ↔ milli conversions.
