1. The nurse is reviewing the laboratory test results of a child diagnosed with disseminated intravascular coagulation (DIC). What would the nurse interpret as indicative of this disorder?
- A. Shortened prothrombin time
- B. Increased fibrinogen level
- C. Positive fibrin split products
- D. Increased platelets
Correct answer: C
Rationale: Positive fibrin split products are indicative of disseminated intravascular coagulation (DIC). In DIC, there is widespread clotting and subsequent consumption of clotting factors, leading to the formation of fibrin split products. A shortened prothrombin time (Choice A) is not typically seen in DIC as it indicates faster clotting, which is opposite to the pathophysiology of DIC. An increased fibrinogen level (Choice B) may be observed in the early stages of DIC due to the compensatory increase in production, but it is not a definitive indicator. Increased platelets (Choice D) may be seen in the early stages of DIC due to the body's attempt to compensate for clot formation, but it is not a specific finding for DIC.
2. The nurse is caring for a client with a central venous catheter. What is the most important action for the nurse to take to prevent infection?
- A. Change the catheter dressing every 72 hours.
- B. Flush the catheter with heparin solution daily.
- C. Ensure the catheter is clamped when not in use.
- D. Maintain sterile technique when handling the catheter.
Correct answer: D
Rationale: Maintaining sterile technique when handling a central venous catheter is crucial in preventing infections. Changing the catheter dressing every 72 hours, while important for overall catheter care, does not directly address infection prevention. Flushing the catheter with heparin solution daily is essential for maintaining patency but does not primarily prevent infections. Ensuring the catheter is clamped when not in use is important for preventing air embolism but is not the most critical action to prevent infection. The most effective way to prevent infections is by strictly adhering to sterile techniques during catheter handling, which minimizes the risk of introducing pathogens into the catheter site.
3. A client in a provider’s office tells the nurse that, 'I fast for several days each week to help control my weight.' The client takes several medications for various chronic issues. The nurse should explain to the client that which of the following mechanisms that result from fasting puts her at risk for medication toxicity?
- A. Increasing the metabolism of the medications over time
- B. Increasing the protein-binding response
- C. Increasing medications’ transit time through the intestines
- D. Decreasing the excretion of medications
Correct answer: B
Rationale: Fasting can lead to an increased protein-binding response of medications. This can result in a higher concentration of bound medications in the bloodstream, potentially causing toxicity as the medications may not be readily available for metabolism or excretion. Choice A is incorrect because fasting typically doesn't increase medication metabolism. Choice C is incorrect as fasting usually decreases transit time through the intestines. Choice D is incorrect since fasting generally does not decrease medication excretion.
4. The nurse is caring for a client who is NPO (nothing by mouth) due to a small bowel obstruction. Which nursing intervention is most important?
- A. Monitor bowel sounds
- B. Provide frequent oral care
- C. Encourage ambulation
- D. Measure abdominal girth
Correct answer: B
Rationale: Providing frequent oral care is crucial when a client is NPO to ensure comfort and prevent drying of the oral mucosa. In this situation, the priority is maintaining oral hygiene to prevent complications such as oral mucosa breakdown. Monitoring bowel sounds may be important in assessing bowel activity, but it is not the priority when the client is NPO due to a small bowel obstruction. Encouraging ambulation can be beneficial for other conditions, but in this case, oral care takes precedence. Measuring abdominal girth is more relevant for assessing abdominal distention, which is not the priority when the client is NPO. Therefore, the most important nursing intervention is to provide frequent oral care.
5. Community health nurses help influence the health of communities through which of the following actions?
- A. legislating health behavior
- B. recording health status of individuals in a similar geographic region
- C. influencing health status and behavior, and engaging in health promotion
- D. none of the above
Correct answer: C
Rationale: Community health nurses play a crucial role in influencing the health of communities by engaging in health promotion activities and influencing health behaviors. Choice A is incorrect as community health nurses do not legislate health behavior but rather educate and promote healthy behaviors. Choice B is incorrect as while community health nurses may record health data, their main focus is on proactive health promotion and intervention, not just documenting health status. Choice D is incorrect because community health nurses actively work to influence health status and behaviors.
