1. Which laboratory test should the nurse monitor to determine the effectiveness of heparin therapy for a client with deep vein thrombosis?
- A. Platelet count
- B. Prothrombin time (PT)
- C. Activated partial thromboplastin time (aPTT)
- D. Hemoglobin and hematocrit
Correct answer: C
Rationale: The activated partial thromboplastin time (aPTT) is the specific laboratory test used to monitor the effectiveness of heparin therapy in patients with deep vein thrombosis. It measures the time it takes for blood to clot and is crucial in assessing the therapeutic range of heparin. Platelet count, prothrombin time (PT), and hemoglobin and hematocrit levels are important parameters in assessing coagulation and blood status but do not directly indicate the effectiveness of heparin therapy.
2. A client wants to increase her daily intake of omega-3 fatty acids. Which of the following foods should the nurse suggest the client increase?
- A. Blueberries
- B. Soybean oil
- C. Citrus fruits
- D. Green tea
Correct answer: B
Rationale: The correct answer is B: Soybean oil. Soybean oil is a good source of omega-3 fatty acids, which are beneficial for heart health. Blueberries (choice A), citrus fruits (choice C), and green tea (choice D) are not significant sources of omega-3 fatty acids. Blueberries are rich in antioxidants, citrus fruits provide vitamin C, and green tea contains polyphenols, but they do not offer a substantial amount of omega-3 fatty acids compared to soybean oil.
3. At a motor vehicle collision site, a nurse applies pressure to a groin wound that is bleeding profusely until emergency personnel arrive. Subsequently, the client undergoes leg amputation and sues the nurse for malpractice. What is the most likely outcome of this lawsuit?
- A. The Patient's Bill of Rights protects clients from malicious intents, so the nurse could lose the case.
- B. The lawsuit may be settled out of court, but the nurse's license is unlikely to be revoked.
- C. There will be no judgment against the nurse, as their actions were protected under the Good Samaritan Act.
- D. The client will win because the four elements of negligence (duty, breach, causation, and damages) cannot be proved.
Correct answer: C
Rationale: The Good Samaritan Act shields healthcare professionals who act in good faith and offer reasonable care from malpractice claims, irrespective of the client's outcome. In this scenario, the nurse stopping to render aid at the accident scene and applying pressure to the bleeding groin wound would likely be covered by the Good Samaritan Act, protecting the nurse from legal repercussions related to the subsequent leg amputation.
4. A nurse manager in the emergency department considers policy changes in the organization and changes in the community, and tries to predict how these may impact the functioning of the unit. Which of the following decisional activities best describes this manager's actions?
- A. Resource allocation
- B. Monitoring
- C. Job analysis and redesign
- D. Planning for the future
Correct answer: D
Rationale: The correct answer is 'Planning for the future.' In this scenario, the nurse manager is engaging in strategic planning by considering policy changes and community dynamics to forecast potential impacts on the unit's functioning. This decisional activity involves anticipating future changes, challenges, and opportunities, and preparing the unit to adapt accordingly. Choice A, 'Resource allocation,' involves distributing resources effectively to support daily operations, which is not the primary focus of the nurse manager's actions described. Choice B, 'Monitoring,' typically involves overseeing current activities and performance to ensure adherence to standards and goals, rather than proactively planning for future changes as the nurse manager is doing. Choice C, 'Job analysis and redesign,' pertains to evaluating and modifying job roles and responsibilities within the unit, which is not directly related to the strategic forecasting and planning involved in anticipating organizational and community impacts.
5. A client with end-stage renal disease (ESRD) is scheduled for hemodialysis. Which assessment finding should be reported to the healthcare provider immediately?
- A. Blood pressure of 110/70 mmHg
- B. Heart rate of 80 beats per minute
- C. Fever of 100.4°F
- D. Respiratory rate of 24 breaths per minute
Correct answer: C
Rationale: The correct answer is C. A fever of 100.4°F is most concerning in a client with ESRD scheduled for hemodialysis as it may indicate an underlying infection, which can lead to serious complications in this population. Elevated body temperature can be a sign of sepsis, which requires immediate attention to prevent further deterioration. Reporting this finding promptly allows for timely intervention. Choices A, B, and D are within normal ranges and do not pose an immediate threat to the client's well-being in the context of preparing for hemodialysis.
