TEAS - Test of Essential Academic Skills Reading Practice Test #4 1

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?

Accepted Answer

Geographic concentration of unvaccinated individuals can undermine population-level immunity even when average coverage appears adequate

Answer

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:

Accepted Answer

Establish why early detection has clinical significance by showing the continuum of worsening damage

Answer

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?

Accepted Answer

To identify specific areas or time periods where compliance gaps exist so targeted interventions can be applied

Answer

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:

Accepted Answer

The second sentence introduces a modifying factor that complicates the straightforward risk presented in the first sentence

Answer

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?

Accepted Answer

Patients may be moved between rooms or beds, making location an unreliable identifier

Answer

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.
