1. Which of the following statements refers to criteria?

A. Agreed on level of nursing care
B. Characteristics used to measure the level of nursing care
C. Step-by-step guidelines
D. Statement which guide the group in decision making and problem solving

Correct answer: B

Rationale: Criteria are specific characteristics or standards used to evaluate or measure the quality or level of something. In this case, statement B, 'Characteristics used to measure the level of nursing care,' correctly refers to criteria because it highlights the specific attributes that are used to assess the quality or level of nursing care provided. The other options do not directly address the concept of criteria. Option A describes an agreed-upon level of care but does not specifically refer to criteria. Option C describes step-by-step guidelines, which are more related to processes or procedures. Option D mentions statements that guide decision-making and problem-solving, which are not necessarily criteria. Therefore, option B is the most appropriate choice as it directly aligns with the definition and concept of criteria.

2. Which of the following is NOT a function of the cilia lining the respiratory tract?

A. Trapping inhaled dust and debris
B. Moistening inhaled air
C. Producing mucus
D. Propelling mucus upwards towards the throat

Correct answer: C

Rationale: The correct answer is C: 'Producing mucus.' Cilia lining the respiratory tract do not produce mucus, but rather move the mucus that is produced by other cells. The cilia work together to propel the mucus upwards towards the throat, where it can be either swallowed or expelled. Trapping inhaled dust and debris, moistening inhaled air, and propelling mucus upwards are all important functions of the cilia in the respiratory tract, helping to protect the lungs and maintain respiratory health.
