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

Overall vaccination rates are high enough to eliminate measles outbreaks nationwide

Answer

The MMR vaccine is less effective than previously reported

Answer

Herd immunity thresholds should be lowered to match current vaccination rates

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

Explain the treatment protocols for each stage of pressure injury

Answer

Argue that Stage 4 injuries are the most common type seen in clinical settings

Answer

Compare pressure injury staging to wound classification systems used in surgery

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

To reduce the total number of observations required each month

Answer

To ensure that high-performing units are not penalized by low-performing ones in performance reviews

Answer

To satisfy accreditation bodies that require unit-level data regardless of its usefulness

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 second sentence contradicts the first by showing sodium has no harmful effect

Answer

The second sentence restates the first sentence using different vocabulary

Answer

The second sentence provides a historical background for the claim made in the first sentence

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

Room numbers are difficult to read in low-light clinical environments

Answer

Date of birth is considered more legally defensible than room number in malpractice cases

Answer

The Joint Commission requires exactly two identifiers and room number does not count as one

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?

Accepted Answer

To explain why nursing evidence hierarchies include multiple research types rather than relying exclusively on RCTs

Answer

To argue that RCTs should be abandoned in favor of qualitative nursing research

Answer

To rank observational studies above expert consensus for clinical decision-making

Answer

To suggest that nursing practice lacks a rigorous scientific foundation compared to other medical fields
