1. What is the transparent membrane that focuses the light entering the eyes onto the retina?

• A. Lens
• B. Sclera
• C. Cornea
• D. Pupils

Correct answer: A

Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina. The sclera is the white outer layer of the eye that helps maintain the shape of the eye, while the cornea is the clear outer covering of the eye that helps to refract light into the eye.

2. How many milliliters are equal to 20 cc?

• A. 2
• B. 20
• C. 2000
• D. 20000

Correct answer: B

Rationale: 1 cc (cubic centimeter) is equal to 1 ml. Therefore, 20 cc is equal to 20 ml. To convert between cubic centimeters (cc) and milliliters (ml), the values are equivalent since they both measure volume in the metric system. Choice A (2) is incorrect as it does not account for the direct conversion between cc and ml. Choice C (2000) and choice D (20000) are incorrect as they represent conversions based on a misunderstanding of the relationship between cc and ml.

3. The physician orders 10 gr of aspirin for a patient. The equivalent dose in milligrams is:

• A. 0.6 mg
• B. 10 mg
• C. 60 mg
• D. 600 mg

Correct answer: D

Rationale: To convert grains (gr) to milligrams (mg), you multiply by 60. Therefore, 10 gr of aspirin is equal to 600 mg (10 gr x 60 = 600 mg). So, the correct answer is 600 mg.

4. A client in the emergency department is experiencing an acute asthma attack. Which assessment indicates an improvement in respiratory status?

• A. SaO2 95%
• B. Wheezing
• C. Retraction of sternal muscles
• D. Premature ventricular complexes (PVC's)

Correct answer: A

Rationale: An SaO2 of 95% indicates an improvement in the client's oxygen saturation, suggesting better respiratory status. In asthma exacerbation, a decrease in SaO2 levels would signal worsening respiratory distress. Wheezing, retraction of sternal muscles, and premature ventricular complexes are indicators of respiratory compromise and worsening respiratory status in acute asthma attacks. Monitoring SaO2 levels is crucial in assessing the effectiveness of interventions and guiding treatment decisions.

5. A client is to receive a transfusion of packed RBCs. Which of the following actions should the nurse take?

• A. Prime IV tubing with 0.9% sodium chloride
• B. Use a 24-gauge IV catheter
• C. Obtain filterless IV tubing
• D. Place blood in the warmer for 1 hr

Correct answer: A

Rationale: Prior to administering a blood transfusion, it is essential to prime the IV tubing with 0.9% sodium chloride to prevent hemolysis of the blood cells. Using a smaller gauge IV catheter (e.g., 20 or 22 gauge) is recommended for blood transfusions to prevent hemolysis. Filterless IV tubing is contraindicated for blood transfusions as it does not have a filter to trap potential blood clots or debris. Warming blood is unnecessary and could lead to the development of bacteria in the blood product. Therefore, the correct action for the nurse to take is to prime the IV tubing with 0.9% sodium chloride.
