Nokea
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 retired nurse stops to help in an emergency at the scene of an accident, if the injured party files suit and the, the nurse would probably be covered by
- A. Her homeowner's insurance
- B. National Care Act
- C. Her automobile insurance
- D. The Good Samaritan Law
Correct Answer: D
Rationale: The Good Samaritan Law offers legal protection to individuals who voluntarily provide assistance at the scene of an emergency or accident. These laws vary by state, but generally, they grant immunity from civil liability for the individual providing aid as long as they act in good faith and without expectation of compensation. In this case, the retired nurse who stopped to help in the emergency at the scene of an accident would likely be covered by the Good Samaritan Law, protecting her from being sued by the injured party for any unintended consequences of her efforts to assist.
The purpose why the head nurse asked Nurse Rosie to submit an IR is to ______.
- A. note patterns of incidences in the same unit
- B. place it in Nurse Rosie's 201 file
- C. document immediately the incident
- D. evaluate Nurse Rosie's performance
Correct Answer: A
Rationale: The purpose of asking Nurse Rosie to submit an Incident Report (IR) is most likely to note patterns of incidences in the same unit. Incident reports are essential tools in healthcare settings to track and analyze unexpected events, errors, or situations that may impact patient care and safety. By collecting and reviewing incident reports, the head nurse can identify trends, patterns, or commonalities in the occurrences within the unit. This information allows for targeted interventions, improvements in practices, and enhanced patient safety. Therefore, asking Nurse Rosie to submit an IR would serve the purpose of noting patterns of incidences in the same unit for proactive and quality care delivery.
The patient 's wife is-so anxious about the condition of her husband. The MOST appropriate INITIAL intervention for the nurse to make is to ________.
- A. describe her husband 's medical treatment since admission
- B. reassure her that the important fact is her presence
- C. explain the nature of the injury and reassure her that husband's condition is stable
- D. allow her to verbalize her feelings and concerns
Correct Answer: C
Rationale: In situations where a patient's family member is expressing anxiety about their loved one's condition, it is important for the nurse to provide clear and accurate information about the patient's status. By explaining the nature of the injury and reassuring the wife that her husband's condition is stable, the nurse can help alleviate her anxiety and address her concerns in a meaningful way. This intervention focuses on open communication and providing emotional support, which are crucial in helping the family member cope with the situation. It is essential to establish trust and create a supportive environment for the family member during this stressful time.
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.
A patient admitted to the ICU develops acute exacerbation of chronic heart failure (CHF) with pulmonary edema and respiratory distress. What intervention should the healthcare team prioritize to manage the patient's exacerbation?
- A. Administer intravenous loop diuretics for fluid removal.
- B. Initiate positive pressure ventilation for respiratory support.
- C. Perform emergent pericardiocentesis for tamponade relief.
- D. Recommend inotropic medications to improve myocardial contractility.
Correct Answer: B
Rationale: In this scenario, the patient is presenting with acute exacerbation of chronic heart failure (CHF) complicated by pulmonary edema and respiratory distress. The priority intervention for managing this exacerbation is to initiate positive pressure ventilation for respiratory support. Positive pressure ventilation, such as non-invasive positive pressure ventilation (NIPPV) or invasive mechanical ventilation, can help improve oxygenation and decrease the work of breathing for the patient. By providing adequate respiratory support, ventilation can reduce the negative effects of pulmonary edema and respiratory distress due to CHF exacerbation. Administering intravenous loop diuretics (Choice A) might be necessary to address fluid overload, but it is not the initial priority as ensuring adequate ventilation is crucial. Emergent pericardiocentesis (Choice C) is not indicated in this scenario as there is no mention of cardiac tamponade. Inotropic medications (Choice D) may be considered in managing acute exacerbation of CHF but
