1. How can medication bound to protein affect drug availability?
- A. enhanced drug availability
- B. rapid distribution of the drug to receptor sites
- C. less availability to produce desired medicinal effects
- D. increased metabolism of the drug by the liver
Correct answer: C
Rationale: Medication bound to protein reduces the availability of the drug to produce desired medicinal effects because only unbound drugs can effectively bind to active receptor sites. When a drug is bound to protein, it cannot bind with receptor sites, limiting its therapeutic impact. Choice A is incorrect because drug availability is reduced when it is bound to protein. Choice B is incorrect as rapid distribution to receptor sites is not possible if the drug is bound to protein and cannot bind with receptors. Choice D is incorrect as metabolism does not increase when the drug is bound to protein; the liver first needs to separate the drug from the protein before metabolism can occur.
2. The client with a myocardial infarction comes to the nurse's station stating that he is ready to go home because there is nothing wrong with him. Which defense mechanism is the client using?
- A. Rationalization
- B. Denial
- C. Projection
- D. Conversion reaction
Correct answer: B
Rationale: The correct answer is B: Denial. The client displaying denial refuses to acknowledge the reality of having a myocardial infarction. Rationalization (choice A) involves making excuses for behavior, not denying a condition. Projection (choice C) is attributing one's thoughts or feelings to others, not denying an illness. Conversion reaction (choice D) is converting psychological distress into physical symptoms, which is not evident in this scenario. Therefore, denial is the defense mechanism being used in this situation.
3. Which client can best be assigned to the newly licensed practical nurse?
- A. The client receiving chemotherapy
- B. The client post-coronary bypass
- C. The client with a TURP
- D. The client with diverticulitis
Correct answer: D
Rationale: The best client to assign to the newly licensed nurse is the most stable client. In this case, the client with diverticulitis is the most stable among the options provided. Clients receiving chemotherapy and those post-coronary bypass require specialized care and attention, making them unsuitable for a newly licensed nurse. The client with a TURP may be at risk of bleeding, needing a nurse experienced in managing such complications. Therefore, the client with diverticulitis is the most appropriate choice for the newly licensed practical nurse.
4. In the emergency room, a nurse is responsible for triaging four clients injured in a motor vehicle accident. Which of the following clients should receive priority in care?
- A. A 10-year-old with lacerations on the face
- B. A 15-year-old with sternal bruises
- C. A 34-year-old with a fractured femur
- D. A 50-year-old with a dislocated elbow
Correct answer: B
Rationale: The 15-year-old with sternal bruises should receive priority in care as this client might be experiencing airway and oxygenation problems. Airway issues take precedence in triage. The 10-year-old with lacerations on the face, although looking bad, is not in immediate distress. The 34-year-old with a fractured femur should be immobilized but can be seen after the client with sternal bruising. The 50-year-old with a dislocated elbow can also be seen later as dislocated elbows are not life-threatening compared to potential airway compromise.
5. The client with cirrhosis of the liver is receiving Lactulose. The nurse is aware that the rationale for the order for Lactulose is:
- A. To lower the blood glucose level
- B. To lower the uric acid level
- C. To lower the ammonia level
- D. To lower the creatinine level
Correct answer: C
Rationale: Lactulose is administered to the client with cirrhosis to lower ammonia levels, as it works by acidifying the colon, trapping ammonia for elimination in the stool. Choices A, B, and D are incorrect because Lactulose does not have an effect on blood glucose, uric acid, or creatinine levels. Therefore, the correct answer is to lower the ammonia level.
