TEAS - Test of Essential Academic Skills Reading Practice Test #4 1 — Questions and Answers
Question 1: A public health report states: 'Vaccination coverage among children aged 2 years reached 91% for the MMR vaccine in 2023, yet measles outbreaks continue to occur in communities with geographic clustering of unvaccinated individuals. Herd immunity thresholds of 95% are required to prevent sustained transmission.' What conclusion is best supported by this passage?
- Overall vaccination rates are high enough to eliminate measles outbreaks nationwide
- Geographic concentration of unvaccinated individuals can undermine population-level immunity even when average coverage appears adequate (Correct answer)
- The MMR vaccine is less effective than previously reported
- Herd immunity thresholds should be lowered to match current vaccination rates
Correct answer: Geographic concentration of unvaccinated individuals can undermine population-level immunity even when average coverage appears adequate
The passage explicitly links continued outbreaks not to low overall rates but to clustering of unvaccinated individuals, and notes the 95% threshold has not been met — directly supporting that geographic concentration undermines protection even when averages look acceptable.
Question 2: A nursing textbook reads: 'Pressure injuries progress through four recognized stages based on tissue involvement, from Stage 1 (non-blanchable erythema of intact skin) to Stage 4 (full-thickness tissue loss with exposed bone, tendon, or muscle). Early identification of Stage 1 injuries is critical because intervention at this point can prevent progression to deeper, more difficult-to-heal wounds.' The primary purpose of describing the staging system in this passage is to:
- Explain the treatment protocols for each stage of pressure injury
- Establish why early detection has clinical significance by showing the continuum of worsening damage (Correct answer)
- Argue that Stage 4 injuries are the most common type seen in clinical settings
- Compare pressure injury staging to wound classification systems used in surgery
Correct answer: Establish why early detection has clinical significance by showing the continuum of worsening damage
The staging description serves as context that makes the final sentence meaningful — the reader understands 'early intervention' matters because the passage shows injuries worsen progressively, lending logical weight to the call for early identification.
Question 3: A hospital policy document states: 'Hand hygiene compliance among clinical staff must be achieved at the following moments: before patient contact, before aseptic procedures, after body fluid exposure, after patient contact, and after contact with patient surroundings. Compliance is monitored through direct observation audits conducted by trained observers who record adherence rates by unit and shift.' What is the most likely reason audits are broken down by unit and shift rather than reported as a single hospital-wide figure?
- To reduce the total number of observations required each month
- To identify specific areas or time periods where compliance gaps exist so targeted interventions can be applied (Correct answer)
- To ensure that high-performing units are not penalized by low-performing ones in performance reviews
- To satisfy accreditation bodies that require unit-level data regardless of its usefulness
Correct answer: To identify specific areas or time periods where compliance gaps exist so targeted interventions can be applied
Disaggregating data by unit and shift allows administrators to pinpoint where and when compliance is weakest, making improvement efforts more precise and effective — a purpose the passage implies through its emphasis on monitoring and adherence rates.
Question 4: A dietary guidelines pamphlet reads: 'Sodium intake above 2,300 mg per day is associated with elevated blood pressure in sodium-sensitive individuals. However, potassium-rich foods such as bananas, sweet potatoes, and leafy greens can partially counteract this effect by promoting renal sodium excretion. Therefore, dietary counseling should address both sodium reduction and potassium adequacy.' The relationship between the first two sentences is best described as:
- The second sentence contradicts the first by showing sodium has no harmful effect
- The second sentence introduces a modifying factor that complicates the straightforward risk presented in the first sentence (Correct answer)
- The second sentence restates the first sentence using different vocabulary
- The second sentence provides a historical background for the claim made in the first sentence
Correct answer: The second sentence introduces a modifying factor that complicates the straightforward risk presented in the first sentence
The first sentence establishes sodium as a risk factor; the second does not deny this but introduces potassium as a physiological counterbalance — neither a contradiction nor a restatement, but a nuancing of the initial claim.
Question 5: A medication administration reference card reads: 'Verify the six rights of medication administration — right patient, right drug, right dose, right route, right time, and right documentation — before administering any medication. The right patient check requires two unique identifiers, such as name and date of birth, and must not rely solely on room number or bed assignment.' Why does the reference card specifically warn against relying on room number or bed assignment for patient identification?
- Room numbers are difficult to read in low-light clinical environments
- Patients may be moved between rooms or beds, making location an unreliable identifier (Correct answer)
- Date of birth is considered more legally defensible than room number in malpractice cases
- The Joint Commission requires exactly two identifiers and room number does not count as one
Correct answer: Patients may be moved between rooms or beds, making location an unreliable identifier
The passage implies that room or bed assignment can change — a patient may be transferred — making location a dynamic and therefore unreliable identifier, whereas name and date of birth are stable attributes tied to the individual.
Question 6: A nursing journal abstract states: 'Randomized controlled trials (RCTs) represent the gold standard for evaluating therapeutic interventions, yet most nursing practice questions cannot be answered by RCTs due to ethical constraints, cost, and the complexity of real-world care environments. Consequently, evidence hierarchies in nursing incorporate observational studies, expert consensus, and qualitative research as legitimate, if lower-ranked, sources of evidence.' What is the author's main purpose in this passage?
- To argue that RCTs should be abandoned in favor of qualitative nursing research
- To explain why nursing evidence hierarchies include multiple research types rather than relying exclusively on RCTs (Correct answer)
- To rank observational studies above expert consensus for clinical decision-making
- To suggest that nursing practice lacks a rigorous scientific foundation compared to other medical fields
Correct answer: To explain why nursing evidence hierarchies include multiple research types rather than relying exclusively on RCTs
The author acknowledges RCTs as the gold standard but immediately explains why they are often impractical in nursing contexts, using that limitation to justify why evidence hierarchies appropriately incorporate lower-ranked but still legitimate research designs.
