1. The cellular membrane contributes to all except which of the following?
- A. Cell energy production
- B. Cell permeability
- C. Cell communication
- D. Cell protection
Correct answer: A
Rationale: The cellular membrane is involved in regulating cell permeability, communication, and protection. However, it is not directly involved in energy production. Choice A is the correct answer because the cellular membrane does not produce energy; instead, it regulates the passage of molecules in and out of the cell. Choices B, C, and D are incorrect because the cell membrane plays key roles in controlling what enters and exits the cell, facilitating communication between cells, and providing structural support and protection to the cell.
2. A 16-year-old gravida 1, para 0 client has just been admitted to the hospital with a diagnosis of eclampsia. She is not presently convulsing. Which intervention should the nurse plan to include in the client's nursing care plan?
- A. Assess temperature every hour.
- B. Allow liberal family visitation.
- C. Monitor blood pressure, pulse, and respirations every 4 hours.
- D. Keep an airway at the bedside.
Correct answer: D
Rationale: In the case of eclampsia, the priority intervention is to keep an airway at the bedside. Eclampsia is associated with a high risk of convulsions, and having an airway readily available is crucial for prompt intervention in the event of seizures. Assessing temperature, allowing family visitation, and monitoring vital signs are important aspects of care but ensuring airway patency takes precedence in this situation to manage potential complications and ensure the client's safety.
3. A male client leaves his job at a nearby restaurant and visits the health clinic where he is diagnosed with viral conjunctivitis. While receiving discharge instructions from the nurse, the client states that he is feeling much better and plans to return to work for the afternoon shift. How should the nurse respond?
- A. advise the client to wear a face mask around other people
- B. ask the client what type of work he does at the restaurant
- C. instruct the client to use dark glasses if lighting is bright
- D. explain that the client should stay home for the next few days
Correct answer: D
Rationale: The correct answer is D: explain that the client should stay home for the next few days. Viral conjunctivitis is highly contagious, and the client should avoid close contact with others until it resolves. Returning to work while still contagious can lead to the spread of the infection to coworkers and customers. Choice A is incorrect because wearing a face mask may not provide sufficient protection against spreading the virus in a close work environment. Choice B is irrelevant to the situation as the focus should be on the client's health and preventing the spread of the infection. Choice C is also unrelated to the management of viral conjunctivitis and does not address the contagious nature of the condition.
4. The nurse is preparing to administer a blood transfusion to a client. Which action is most important for the nurse to take before starting the transfusion?
- A. Administer pre-transfusion medication
- B. Ensure the client has an adequate fluid intake
- C. Monitor the client's vital signs
- D. Verify the blood type with another nurse
Correct answer: D
Rationale: Verifying the blood type with another nurse is critical before starting a blood transfusion to prevent a potentially life-threatening transfusion reaction. This step ensures that the client receives the correct blood product. Administering pre-transfusion medication, ensuring adequate fluid intake, and monitoring vital signs are important steps during the transfusion process, but verifying the blood type is the most crucial step to ensure patient safety.
5. A healthcare provider is assessing a client who is receiving treatment for dehydration. Which assessment finding indicates that the client is responding to the treatment?
- A. Dry mucous membranes
- B. Increased urine output
- C. Decreased skin turgor
- D. Elevated heart rate
Correct answer: B
Rationale: Increased urine output is a positive sign indicating that the client is responding to the treatment for dehydration. It suggests that the client's kidneys are functioning better, helping to eliminate excess fluid and waste products from the body. Dry mucous membranes (Choice A) are a sign of dehydration, not improvement. Decreased skin turgor (Choice C) and elevated heart rate (Choice D) are also symptoms of dehydration and do not indicate a positive response to treatment.
