A patient presents with watery diarrhea, abdominal cramps, and nausea after consuming contaminated water from a stream during a camping trip. Laboratory tests reveal oocysts in the stool sample. Which of the following parasites is most likely responsible for this infection?
- A. Giardia lamblia
- B. Entamoeba histolytica
- C. Cryptosporidium parvum
- D. Cyclospora cayetanensis
Correct Answer: C
Rationale: Cryptosporidium parvum is a parasite commonly found in contaminated water sources such as streams or lakes. It causes an infection called cryptosporidiosis, which often presents with symptoms like watery diarrhea, abdominal cramps, and nausea. The oocysts of Cryptosporidium parvum can be identified in stool samples, making it the likely culprit in this scenario. Giardia lamblia, another common waterborne parasite, can also cause similar symptoms but is characterized by trophozoites rather than oocysts in stool samples. Entamoeba histolytica is associated with amoebic dysentery and does not typically present with watery diarrhea. Cyclospora cayetanensis is another parasite causing gastrointestinal symptoms but is not as commonly associated with contaminated water sources as Cryptosporidium parvum.

A nurse is resistant to the change and is not taking an active part in facilitating the process of change. Which is the BEST approach in dealing with the nurse?
- A. Exert coercion on the nurse
- B. Provide a positive reward system for the nurse
- C. Talk and encourage verbalizing feelings of the change
- D. Ignore the resistance of the nurse.
Correct Answer: C
Rationale: The best approach in dealing with a nurse who is resistant to change and not actively participating is to communicate and encourage verbalizing feelings about the change. By talking with the nurse and allowing them to express their concerns and feelings, you can address any underlying issues that may be causing the resistance. This approach can help build trust, improve communication, and ultimately increase the nurse's engagement in the change process. Coercion (Choice A) can create negative feelings and resistance, while ignoring the nurse's resistance (Choice D) will not resolve the issue. Providing positive rewards (Choice B) may be helpful but may not address the underlying reasons for resistance. Communication is key in addressing resistance to change and fostering a positive, open environment for all involved.
When an accurate documentation whether done manually or by electronic by the health care professionals in their Work setting is a component of what quality standards in a health care delivery system?
- A. Patient care standards
- B. Leadership and management
- C. Information management
- D. Human resource management
Correct Answer: C
Rationale: Accurate documentation, whether done manually or electronically by health care professionals, is a critical component of information management in a health care delivery system. Information management involves the collection, storage, processing, and sharing of data to support decision-making and ensure quality care for patients. Properly documented records enable health care providers to have access to relevant information about a patient's medical history, treatment plans, and progress. This helps in delivering effective and coordinated care, reducing medical errors, and improving overall patient outcomes. Moreover, well-kept records are essential for legal and regulatory compliance, billing, quality assessment, and research purposes. Therefore, accurate documentation plays a key role in information management within the healthcare setting.
After the surgical procedure, the nurse assists with applying the surgical dressing. What is the nurse's priority action?
- A. Documenting the dressing change in the patient's chart
- B. Assessing the surgical incision for signs of complications
- C. Providing instructions to the patient about wound care
- D. Ensuring that the dressing is applied securely and correctly
Correct Answer: B
Rationale: The nurse's priority action after applying the surgical dressing is to assess the surgical incision for signs of complications. This includes checking for any signs of infection, excessive bleeding, or other complications related to the surgical site. Early detection of such complications is crucial for ensuring proper healing and preventing serious complications. Once the assessment is done and any issues are addressed, the nurse can proceed with documenting the dressing change, providing instructions to the patient about wound care, and ensuring that the dressing is securely and correctly applied.
Ms. C is at risk for refeeding syndrome that is caused by rapid feeding. What should be the priority action of the health care team to prevent complications associated with this syndrome?
- A. Assess for signs of pallor of the extremities and sluggish capillary refill
- B. Monitor for decreased bowel sounds, nausea, bloating, and abdominal distention
- C. Observe for signs of secret purging and ingestion of water to increase weight
- D. Monitor for peripheral edema, crackles in the lungs, and jugular vein distention
Correct Answer: B
Rationale: Refeeding syndrome is a potentially dangerous condition that can occur in malnourished individuals when nutrition is reintroduced too quickly. It is characterized by shifts in electrolytes, fluid imbalance, and metabolic abnormalities. Monitoring for decreased bowel sounds, nausea, bloating, and abdominal distention is the priority action to prevent complications associated with refeeding syndrome. These symptoms can indicate gastrointestinal issues such as ileus or overfeeding, which can lead to further complications. Early recognition and intervention can help prevent serious consequences of refeeding syndrome.
A patient presents with a displaced fracture of the distal radius and ulna after a fall. What is the preferred initial treatment for this injury?
- A. Closed reduction and splinting
- B. Open reduction and internal fixation (ORIF)
- C. Closed reduction and external fixation (CREF)
- D. Cast immobilization without reduction
Correct Answer: A
Rationale: In the case of a displaced fracture of the distal radius and ulna, the preferred initial treatment is typically closed reduction and splinting. Closed reduction involves manually realigning the fractured bones without the need for surgery. Splinting is then utilized to immobilize the wrist and forearm to allow for proper healing of the fracture. This approach is often effective in realigning the bones and stabilizing the injury, allowing for adequate healing without the need for more invasive interventions like surgery. Following the initial management with closed reduction and splinting, the patient's progress will be monitored, and further interventions may be considered based on the specific characteristics of the fracture and the patient's response to treatment.
