TEAS Reading Practice Test #4 2

Question 1

A nursing journal article states: 'Despite widespread adoption of fall prevention protocols, hospital fall rates have plateaued at approximately 3.5 per 1,000 patient-days. New research suggests that individualized risk assessments, rather than standardized checklists, may be more effective at reducing falls among high-risk populations.' What is the author's main argument?

Accepted Answer

Standardized approaches have reached their limit and individualized methods may work better

Answer

The author presents the plateau in fall rates despite current protocols and suggests individualized approaches as a potentially superior alternative.

Question 2

Read the following passage from a pharmacology text: 'First-generation antihistamines such as diphenhydramine readily cross the blood-brain barrier, causing drowsiness. Second-generation antihistamines like loratadine were designed to be less lipophilic, significantly reducing CNS penetration and sedative effects while maintaining peripheral H1 receptor blockade.' The relationship between the two sentences is best described as:

Accepted Answer

The second sentence describes a solution developed in response to the limitation in the first

Answer

The first sentence identifies a problem (drowsiness from first-generation antihistamines), and the second describes how second-generation drugs were designed to address that limitation.

Question 3

A clinical guideline reads: 'For patients with Type 2 diabetes, metformin remains the first-line pharmacological therapy (Level A evidence). When glycemic targets are not met with metformin alone, adding a second agent should be individualized based on patient characteristics, comorbidities, and cost considerations (Level B evidence).' What does the difference in evidence levels suggest?

Accepted Answer

There is stronger research support for metformin as first-line therapy than for choosing specific second-line agents

Answer

Level A evidence typically indicates the strongest research support (e.g., multiple large RCTs), while Level B suggests good but less robust evidence, indicating more certainty about metformin as first-line treatment.

Question 4

An instruction manual for a blood glucose monitor states: 'Step 1: Wash hands with warm soapy water and dry thoroughly. Step 2: Insert a new test strip into the monitor. Step 3: Use the lancing device to obtain a blood sample from the side of a fingertip. Step 4: Touch the blood drop to the edge of the test strip.' Why does the manual specify 'the side of a fingertip' in Step 3?

Accepted Answer

The side of the fingertip has fewer nerve endings, causing less pain

Answer

The sides of fingertips have fewer nerve endings than the pads, so lancing there causes less pain while still providing an adequate blood sample.

Question 5

A research abstract concludes: 'Our findings suggest that nurse staffing ratios are inversely associated with patient mortality rates. Hospitals with ratios below 1:4 showed a 14% increase in 30-day mortality compared to those maintaining 1:4 or better.' What does 'inversely associated' mean in this context?

Accepted Answer

As staffing ratios worsen (fewer nurses per patient), mortality rates increase

Answer

An inverse association means the variables move in opposite directions—as nurse-to-patient ratios worsen (fewer nurses), mortality increases.
