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. Which of the following measures is not recommended to prevent pressure ulcers?
- A. Massaging the reddened area with lotion
- B. Using a water or air mattress
- C. Adhering to a schedule for positioning and turning
- D. Providing meticulous skin care
Correct answer: A
Rationale: Massaging a reddened area can cause further tissue damage by increasing pressure on already compromised skin. The other options, such as using specialized mattresses, adhering to repositioning schedules, and maintaining good skin care, are all recommended strategies to prevent pressure ulcers by reducing pressure and friction on vulnerable areas of the skin.
3. A healthcare provider is reviewing the laboratory report of a client who has been taking lithium carbonate for the past 12 months. The provider notes a lithium level of 0.8 mEq/L. Which of the following orders from the provider should the healthcare provider expect?
- A. Withhold the next dose
- B. Increase the dosage
- C. Discontinue the medication
- D. Administer the medication
Correct answer: D
Rationale: A lithium level of 0.8 mEq/L falls within the therapeutic range for maintaining the drug's effectiveness while minimizing toxicity. Therefore, the appropriate action would be to continue administering the medication as prescribed by the healthcare provider to maintain the therapeutic effect for the client.
4. The physician orders the administration of high-humidity oxygen by face mask and placement of the patient in a high Fowler’s position. After assessing Mrs. Paul, the nurse writes the following nursing diagnosis: Impaired gas exchange related to increased secretions. Which of the following nursing interventions has the greatest potential for improving this situation?
- A. Encourage the patient to increase her fluid intake to 200 ml every 2 hours
- B. Place a humidifier in the patient’s room
- C. Continue administering oxygen by high humidity face mask
- D. Perform chest physiotherapy on a regular schedule
Correct answer: D
Rationale: Chest physiotherapy is the most effective intervention in cases of impaired gas exchange related to increased secretions. This technique helps mobilize and clear secretions from the airways, thereby improving gas exchange in the lungs. Placing a humidifier or administering oxygen by high humidity face mask may provide moisture but may not directly address the clearance of secretions. Encouraging increased fluid intake can help with hydration but may not address the underlying issue of impaired gas exchange due to secretions.
5. The healthcare provider orders an IV solution of dextrose 5% in water at 100ml/hour. What would the flow rate be if the drop factor is 15 gtt = 1 ml?
- A. 5 gtt/minute
- B. 13 gtt/minute
- C. 25 gtt/minute
- D. 50 gtt/minute
Correct answer: C
Rationale: To determine the flow rate in drops per minute, multiply the ordered volume per hour by the drop factor (100 ml/hour x 15 gtt/ml = 1500 gtt/hour). Then, divide the result by 60 minutes to convert it to drops per minute (1500 gtt/hour ÷ 60 minutes = 25 gtt/minute). Therefore, the correct answer is 25 gtt/minute.
