## CIH-D1-Q001

- **Pack:** cih
- **Type:** question
- **Domain:** exposure-assessment-strategy
- **Topic:** Exposure assessment prioritization
- **Difficulty:** Easy
- **Review status:** accepted

### Stem

Before quantitative air sampling, an IH team ranks tasks by toxicity, frequency, and number of workers exposed. This step best describes:

### Choices

- A) Analytical method validation
- B) Qualitative exposure assessment / prioritization
- C) Medical surveillance enrollment
- D) PPE final selection only

**Correct answer:** B

### Explanation

Qualitative assessment uses professional judgment and available data to prioritize where quantitative measurements and controls are most needed, conserving resources for highest-risk tasks.

## CIH-D1-Q002

- **Pack:** cih
- **Type:** question
- **Domain:** exposure-assessment-strategy
- **Topic:** Similar exposure groups
- **Difficulty:** Medium
- **Review status:** accepted

### Stem

Workers performing the same job on the same shift with comparable tasks and controls are often grouped as a SEG for sampling. The primary benefit is:

### Choices

- A) Eliminating the need for any measurements
- B) Representative sampling that covers workers with similar exposures
- C) Replacing hazard communication
- D) Avoiding medical surveillance

**Correct answer:** B

### Explanation

Similar exposure groups (SEGs) allow representative monitoring: results from sampled workers can be applied to the group when tasks, controls, and materials are truly comparable.

## CIH-D1-Q003

- **Pack:** cih
- **Type:** question
- **Domain:** exposure-assessment-strategy
- **Topic:** Sampling strategy scenario
- **Difficulty:** Hard
- **Review status:** accepted

### Stem

A solvent exposure varies widely by task duration. Which strategy most improves interpretation of a worker's true shift exposure?

### Choices

- A) One 15-minute grab sample per month
- B) Full-shift personal sampling on high-variability days plus task notes
- C) Area sample at the roof vent only
- D) Post-shift urine test without workplace data

**Correct answer:** B

### Explanation

Variable exposures require personal, full-shift samples tied to task documentation. Short grab samples or remote area samples may miss peak tasks or misrepresent personal dose.

- **Difficulty:** Medium
- **Review status:** accepted

### Stem

When planning an exposure assessment, defining acceptable uncertainty, sample numbers, and decision criteria before sampling aligns with:

### Choices

- **Type:** question
- **Domain:** exposure-assessment-strategy
- **Topic:** Baseline vs periodic monitoring
- **Difficulty:** Easy

- C) 15.0
- D) 10.0

**Correct answer:** B

### Explanation

Risk among exposed = 20/200 = 10.0%. Risk among unexposed = 8/800 = 1.0%. RR = 0.1000/0.0100 ≈ 10.0.

In a cohort study, 10 of 50 exposed workers and 19 of 950 unexposed workers developed illness. What is the approximate relative risk (RR)?

### Choices

- A) 5.0
- B) 10.0
- C) 15.0
- D) 20.0

**Correct answer:** B

### Explanation

Risk among exposed = 10/50 = 20.0%. Risk among unexposed = 19/950 = 2.0%. RR = 0.2000/0.0200 ≈ 10.0.
