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?

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.

Correct Answer: C

Rationale: Meningomyelocele is a type of neural tube defect where there is a protrusion of the spinal cord, cerebrospinal fluid, and meninges through a defect in the vertebrae, forming a sac on the surface of the back. This condition occurs during fetal development when the neural tube fails to close completely, leading to the exposure of the spinal cord and its coverings. This herniation can result in a range of neurological deficits and complications, requiring surgical repair shortly after birth to prevent further damage and infections.

Correct Answer: A

Rationale: The recommended position for a conscious patient experiencing an acute asthma exacerbation is the High-Fowler's position. This position involves the patient sitting upright or almost upright at about a 90-degree angle. The High-Fowler's position helps improve ventilation by expanding the lungs and maximizing airflow in and out of the airways. It also reduces the work of breathing in patients with asthma by allowing gravity to assist in moving air in and out of the lungs more easily. Additionally, this position can help alleviate shortness of breath and improve oxygenation in patients experiencing an asthma exacerbation.

Correct Answer: C

Rationale: Nurse Filomena would consider the purpose of the health fair to be multiphasic screening. A multiphasic screening event involves offering various health screening tests at the same time to individuals within the community. These screenings aim to detect a range of health conditions early on, ultimately promoting prevention and early intervention. By organizing a health fair with several screening tests being given simultaneously, Nurse Filomena's primary goal is likely to help identify health issues in the community proactively and provide education and resources for ongoing health promotion and disease prevention. While aspects of community service, community bonding, and case finding may also be outcomes of the health fair, the focus on conducting multiple screening tests aligns most closely with the concept of multiphasic screening as the primary purpose.

Correct Answer: B

Rationale: In a patient with acute respiratory failure and hypercapnia due to a COPD exacerbation, the most appropriate intervention is the initiation of non-invasive positive pressure ventilation (NIPPV). NIPPV helps improve ventilation and oxygenation by providing mechanical support to the patient's breathing without the need for endotracheal intubation. It can reduce the work of breathing, decrease carbon dioxide retention, and improve respiratory muscle function. This intervention is particularly beneficial for COPD exacerbations as it can help alleviate hypercapnia and hypoxemia, leading to improved outcomes and potentially reducing the need for invasive ventilation methods. Therefore, NIPPV is the recommended management strategy in this scenario.

Correct Answer: B

Rationale: Option B, "Be sure to rebut the patient point by point," is NOT the way to handle complaints. When dealing with patient complaints, it is important to take a calm and empathetic approach rather than engaging in a defensive or confrontational manner. Rebutting the patient point by point can escalate the situation and may further alienate the patient. Effective complaint management involves active listening, showing empathy, addressing concerns, and working towards a resolution that benefits both the patient and the healthcare provider.

Correct Answer: C

Rationale: The patient is presenting with sudden-onset weakness and sensory loss on one side of the body along with difficulty speaking and understanding speech, which are classic symptoms of a stroke. The involvement of the right middle cerebral artery territory on imaging suggests an acute infarction, confirming an ischemic stroke. Ischemic stroke occurs due to a blockage or obstruction within a blood vessel supplying blood to the brain, leading to a lack of oxygen and nutrients reaching brain tissue. This results in neurological deficits corresponding to the affected area of the brain. In contrast, a transient ischemic attack (TIA) would present with similar symptoms but resolve within 24 hours without evidence of acute infarction on imaging. Intracerebral hemorrhage and subarachnoid hemorrhage involve bleeding into the brain tissue or the space surrounding the brain, respectively, resulting in different clinical presentations.

Correct Answer: A

Rationale: The ultimate purpose of record-keeping is to safeguard information. While history, archiving, and storing information are all important functions of record-keeping, safeguarding information stands out as the primary goal. Keeping accurate and accessible records ensures that essential information is secured, protected from unauthorized access, loss, and damage. Safeguarding information also promotes transparency, accountability, and compliance with legal and ethical standards. In the case of Nurse Mely's consideration of teamwork and collaboration in community health nursing, safeguarding the relevant information through precise and organized record-keeping is crucial for effective communication, continuity of care, and successful health outcomes.

Correct Answer: B

Rationale: The patient can tell all information to the nurse once the feeling of security is established in the nurse-patient relationship. Open communication and sharing of information are essential components of nursing care. Patients are more likely to disclose personal information, concerns, and feelings when they trust their nurse and feel secure in the relationship. Building trust and creating a safe and supportive environment are crucial for effective therapeutic communication and holistic patient care. It is important for the nurse to establish a trusting relationship with the patient to encourage open communication and provide patient-centered care.
