1. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). The nurse should monitor the client for which of the following laboratory values?
- A. Prothrombin time (PT)
- B. Serum potassium
- C. Blood urea nitrogen (BUN)
- D. White blood cell count (WBC)
Correct answer: A
Rationale: The correct answer is A: Prothrombin time (PT). Prothrombin time is monitored to assess the effectiveness of warfarin therapy. Warfarin is an anticoagulant medication that works by inhibiting the synthesis of vitamin K-dependent clotting factors, including factors II, VII, IX, and X. Monitoring the PT helps ensure that the client's blood is clotting within the desired therapeutic range to prevent complications such as recurrent DVT or excessive bleeding. Choices B, C, and D are incorrect because serum potassium, blood urea nitrogen, and white blood cell count are not directly related to monitoring warfarin therapy in a client with a history of DVT.
2. Which presentation of an infectious disease is acquired through an indirect transmission?
- A. Syphilis contracted from a sexual partner.
- B. Measles resulting from a daycare center outbreak.
- C. Malaria following exposure in a mosquito-infested area.
- D. Nosocomial influenza spreading rapidly in a long-term care center.
Correct answer: C
Rationale: The correct answer is C. Malaria is transmitted indirectly through mosquito bites. Choice A is incorrect as syphilis is acquired through direct contact with an infected sexual partner. Choice B is incorrect as measles can be transmitted through respiratory droplets in close contact settings like daycare centers. Choice D is incorrect as nosocomial influenza spreads within healthcare facilities through direct contact or droplets.
3. The nurse is teaching a client about the healthy use of ego defense mechanisms. An appropriate goal for this client would be
- A. Reduce fear and protect self-esteem
- B. Minimize anxiety and delay apprehension
- C. Avoid conflict and leave unpleasant situations
- D. Increase independence and communicate more effectively
Correct answer: A
Rationale: The correct answer is A: 'Reduce fear and protect self-esteem.' When teaching a client about the healthy use of ego defense mechanisms, the goal is to help the individual manage emotions effectively without denying reality. Using defense mechanisms in a healthy way aims to reduce fear and protect self-esteem while still addressing underlying issues. Choices B, C, and D are incorrect because they do not focus on the core principles of using defense mechanisms in a healthy manner. Minimizing anxiety and delaying apprehension, avoiding conflict and leaving unpleasant situations, and increasing independence and communicating more effectively do not directly align with the goal of utilizing ego defense mechanisms in a constructive way.
4. A client has been admitted for meningitis. In reviewing the laboratory analysis of cerebrospinal fluid (CSF), the nurse would expect to note
- A. High protein
- B. Clear color
- C. Elevated sed rate
- D. Increased glucose
Correct answer: A
Rationale: High protein levels in the cerebrospinal fluid are indicative of bacterial meningitis, as the presence of bacteria in the CSF leads to increased protein production. Elevated protein levels can be seen in inflammatory conditions like meningitis. Choice B, clear color, is not expected in meningitis as it is typically associated with cloudy or turbid CSF. Elevated sed rate (choice C) and increased glucose (choice D) are not typically associated with the laboratory findings seen in meningitis.
5. Mark, 9 months old, is given oral rehydration solution because of diarrhea with some dehydration. In your follow-up visit, you observed that Mark's eyes become puffy. Which one of the following would you advise Mark's mother?
- A. continue giving ORS but more slowly
- B. show mother how much solution to give
- C. stop ORS and give plain water or milk
- D. reassess patient to determine how much ORS to give
Correct answer: A
Rationale: In this scenario, observing puffy eyes in a child being treated with oral rehydration solution may indicate fluid overload. Continuing to give ORS but more slowly is the correct course of action as it helps manage hydration without overloading fluids. Choice B is not the best option in this situation as the issue is not about the quantity of the solution, but the rate of administration. Choice C is incorrect because plain water or milk is not a suitable alternative for rehydration in cases of dehydration. Choice D is also incorrect as reassessing the patient does not directly address the issue of puffy eyes, which suggests a need to adjust the administration of ORS.
