1. A healthcare professional is caring for a client who is experiencing respiratory distress. Which of the following early manifestations of hypoxemia should the professional recognize?

A. Confusion
B. Pale skin
C. Bradycardia
D. Hypotension

Correct answer: B

Rationale: Pale skin is an early manifestation of hypoxemia due to decreased oxygenation of the blood. The skin may appear pale as the body redirects blood flow to vital organs in response to low oxygen levels. Confusion, bradycardia, and hypotension may occur as hypoxemia worsens, but pale skin is one of the initial signs that healthcare professionals should recognize when assessing a client experiencing respiratory distress.

2. How many ounces are in 1 cup?

A. 8
B. 80
C. 800
D. 8000

Correct answer: A

Rationale: 1 cup is equivalent to 8 ounces. This conversion is commonly used in cooking and baking recipes, where precise measurements are crucial for the successful outcome of dishes. Knowing this conversion helps ensure that ingredients are accurately measured and the recipe turns out as intended. Choices B, C, and D are incorrect because they do not reflect the correct conversion between cups and ounces. 80, 800, and 8000 ounces are significantly higher quantities than what is found in 1 cup, which is 8 ounces.

3. Which of the following interventions is considered the most effective form of universal precautions?

A. Cap all used needles before removing them from their syringes
B. Discard all used uncapped needles and syringes in an impenetrable protective container
C. Wear gloves when administering IM injections
D. Follow enteric precautions

Correct answer: B

Rationale: The most effective form of universal precautions is to discard all used uncapped needles and syringes in an impenetrable protective container. This practice minimizes the risk of needle-stick injuries, which are a significant concern when dealing with used needles. By safely disposing of uncapped needles, healthcare providers can protect themselves and others from potential exposure to bloodborne pathogens.

4. While teaching a newly hired nurse about varicella, a nurse in a pediatric clinic should include which of the following information?

A. Children who have varicella are contagious until vesicles are crusted.
B. Children who have varicella should receive the varicella (chickenpox) vaccine.
C. Children who have varicella should be placed in airborne precautions.
D. Children who have varicella are contagious 1-2 days before the rash appears.

Correct answer: A

Rationale: Children with varicella (chickenpox) are contagious until all vesicles are crusted over. The contagious period starts 1-2 days before the rash appears and continues until all lesions are dried and crusted. It is important to educate healthcare providers about the contagious period to prevent the spread of the virus to susceptible individuals.

5. Which of the following is the correct meaning of CBR?

A. Cardiac Board Room
B. Complete Bathroom
C. Complete Bed Rest
D. Complete Board Room

Correct answer: C

Rationale: In medical terminology, 'CBR' stands for Complete Bed Rest. This term indicates the necessity for a patient to remain in bed without engaging in any physical activities beyond what is essential for daily living, to aid in the recovery process or to prevent further health complications. Choices A, B, and D are incorrect as they do not reflect the medical meaning of CBR.
