HSRT Explanation and Justification of Reasoning

Question 1

A nurse concludes that a patient's fever is probably due to infection. Which statement best JUSTIFIES this conclusion?

Accepted Answer

The patient has an elevated white blood cell count, a productive cough, and chest crackles, all of which are consistent with infection.

Answer

A justification cites specific, relevant evidence that supports the conclusion. The other options are vague, irrelevant, or appeal to opinion rather than evidence.

Question 2

A study reports that a new drug lowered systolic blood pressure by an average of 8 mmHg compared with placebo (p = 0.01). Which explanation of this result is the most accurate?

Accepted Answer

The difference between groups was unlikely to be due to chance alone, so the drug probably has a real effect on average.

Answer

A p-value of 0.01 indicates the observed difference is unlikely under chance alone. It describes a group average, not individual outcomes, and says nothing about safety.

Question 3

Which of the following is the best example of explaining the METHOD used to reach a clinical decision?

Accepted Answer

We compared the patient's symptoms against the diagnostic criteria, ruled out two alternatives with lab tests, and then chose the best-fitting diagnosis.

Answer

Explaining a method means describing the steps and criteria used to reach the conclusion so others can follow and evaluate them.

Question 4

A student says, 'I chose option B because the other options each contradict a fact stated in the passage.' This statement is mainly an example of:

Accepted Answer

Justifying a choice by giving reasons

Answer

The student gives a reason, namely the contradictions with the passage, that supports the choice. That is justification.

Question 5

Which response best explains to a patient why a screening test with a positive result still needs follow-up confirmation?

Accepted Answer

Screening tests can produce false positives, so a second, more specific test is needed to confirm whether the condition is really present.

Answer

This explanation gives the underlying reason, the possibility of false positives, and the logical next step. The other options are inaccurate or unsupported.
