About this Exam
Prepare with the CDC 4H Block One Practice Test practice quiz. This question bank includes 10 questions covering ethical, principle, focus, and block. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
Respiratory therapists may wean patients from mechanical ventilators. Which option correctly reflects that practice?
Explanation:
Weaning from a ventilator means gradually reducing the machine’s support and letting the patient breathe more on their own while checking that gas exchange and work of breathing stay adequate. Respiratory therapists manage this by evaluating readiness, conducting spontaneous breathing trials, adjusting ventilator settings, and monitoring breathing effort, oxygenation, ventilation, and vital signs. The goal is to demonstrate the patient can breathe without help and be extubated when appropriate. Administering oxygen is supportive care used during weaning, but it doesn’t itself describe reducing ventilator support. Thoracentesis is a procedure to remove pleural fluid, not related to the weaning process. Stress tests assess exercise capacity and cardiovascular-respiratory response, not the step-by-step withdrawal from mechanical ventilation.
Question
2
When should the medication label first be checked?
Explanation:
The first moment to verify a medication is when you reach for it in storage. This initial check helps catch errors early—confirm the correct drug name, dose, and that it matches the patient’s orders before you touch or prepare anything. If you wait until after you’ve poured or opened it, you’ve let a potential mistake slip through and you’ve already handled the wrong item. Checking before pouring is important, but it comes after the initial grab as part of the ongoing verification process. Checking after administration is too late to prevent an error from reaching the patient.
Question
3
Which ethical principle focuses on fairness?
Explanation:
Fairness in how benefits and burdens are distributed is what Justice focuses on. In healthcare ethics, Justice means treating people impartially, avoiding discrimination, and using fair processes to allocate resources or access to care based on need and potential benefit. This makes it the best answer for a principle centered on fairness. Beneficence guides doing good for the patient, nonmaleficence guides not causing harm, and veracity deals with truth-telling. An example: when resources are scarce, applying just criteria and a transparent process ensures everyone is treated fairly rather than favoring one patient without justification.
Question
4
Glassware primarily presents which safety concern in a lab?
Explanation:
Glassware safety is mainly about breakage and the sharp edges that can result when it cracks or shatters. Beakers, flasks, and test tubes are strong when used correctly, but they can crack from impacts, thermal stress, or rapid cooling after heating. When glass breaks, the jagged edges can easily cut skin, and tiny shards can pierce fingers or contaminate samples. That’s why the standard precautions focus on inspecting glassware for cracks, never using damaged pieces, handling hot glass with tume forceps or gloves, and cleaning up broken glass with a brush and a designated container. The other hazards—electrical shock, radiation exposure, and chemical fumes—are more about the equipment or substances involved, not the glassware itself, so they aren’t the primary concern with ordinary glassware use.
Question
5
Which ethical principle requires avoiding harm?
Explanation:
Nonmaleficence is the obligation to avoid harming others. In healthcare, it means practitioners should refrain from actions that could injure patients and should minimize risks, avoiding unnecessary or dangerous interventions. When a question asks which principle requires avoiding harm, this principle is the best fit because its central idea is harm avoidance itself. Beneficence focuses on promoting well-being, justice on fair treatment, and autonomy on respecting patient choices, so they don’t center on the act of not harming in the same direct way.
