Which of the following cellular receptors is responsible for recognizing pathogen-associated molecular patterns (PAMPs) and initiating innate immune responses?

Correct Answer: A

Rationale: Toll-like receptors (TLRs) are a group of cellular receptors responsible for recognizing pathogen-associated molecular patterns (PAMPs), which are molecular components commonly found on pathogens like bacteria and viruses. When TLRs recognize these PAMPs, they initiate signaling pathways that trigger the innate immune response, leading to inflammation, antimicrobial defense, and the activation of adaptive immunity. B cell receptors (BCRs) and T cell receptors (TCRs) are involved in adaptive immune responses and recognize specific antigens rather than PAMPs. Fc receptors primarily bind to the Fc portion of antibodies and are involved in antibody-mediated immune responses. Thus, TLRs specifically play a critical role in sensing and responding to pathogens through the recognition of PAMPs.

Correct Answer: D

Rationale: When performing an intramuscular (IM) injection, the nurse should insert the needle at a 90-degree angle into the muscle. This angle helps ensure proper and deep penetration into the muscle tissue for effective administration of the medication. It also helps prevent leakage or tissue damage at the injection site. Additionally, inserting the needle at a 90-degree angle facilitates accurate delivery of the medication into the muscle where it can be absorbed properly. Therefore, selecting the correct angle for inserting the needle is critical in ensuring the success and effectiveness of the IM injection.

Correct Answer: D

Rationale: Ovarian torsion is the most likely cause of the pregnant woman's symptoms as described. Ovarian torsion occurs when the ovary twists on its pedicle, leading to compromised blood flow to the ovary. This can cause severe abdominal pain, bloating, and constipation. On examination, an abdominal mass may be palpable due to an enlarged, twisted ovary. Bowel sounds may be diminished due to the effect of the torsion on surrounding structures. Ectopic pregnancy, threatened abortion, and placenta previa are less likely to present with an abdominal mass and diminished bowel sounds.

Correct Answer: C

Rationale: Allowing people's participation to confirm the health problems would yield better results in facilitating the recognition of the community's health issues. By involving the community members themselves in the process of identifying and acknowledging their health problems, there is a higher likelihood of garnering accurate and relevant information. This participatory approach fosters a sense of ownership and empowerment among the community members, making them more likely to actively engage in addressing the identified health concerns. Additionally, community participation can help build trust between the nurse and the residents, leading to more effective communication and collaboration in improving overall health outcomes.

Correct Answer: C

Rationale: Chest pain, dyspnea, hypotension, and ST-segment elevation on an ECG in the inferior leads are classic signs of an acute myocardial infarction (MI). An acute MI occurs when there is a sudden blockage of blood flow to a part of the heart muscle, leading to tissue damage. This causes symptoms such as chest pain due to ischemia, dyspnea due to heart failure, and hypotension due to poor cardiac output. The ST-segment elevation seen on the ECG is indicative of significant myocardial injury. Prompt diagnosis and management are crucial in acute MI to prevent further complications and to minimize damage to the heart muscle. It is important to differentiate an acute MI from stable or unstable angina or other cardiovascular disorders, as the management and prognosis vary significantly.

Correct Answer: C

Rationale: Cryptosporidium parvum is a protozoan parasite often found in contaminated water sources. This parasite is known to cause watery diarrhea, abdominal cramps, and nausea in infected individuals. The presence of oocysts in the stool sample is characteristic of Cryptosporidium infection. Other parasitic infections may present with similar symptoms, but in this case, the most likely culprit based on the exposure history and laboratory findings is Cryptosporidium parvum.

Correct Answer: D

Rationale: Nurse Noli should not advise patients to eat more saturated fats. Saturated fats are known to increase cholesterol levels and can lead to heart disease and other health issues. It is recommended to limit the intake of saturated fats in the diet. Therefore, advising patients to eat more saturated fats goes against the goal of promoting heart-healthy habits. Instead, Nurse Noli should focus on encouraging patients to cut down on salt intake, consume more fruits and vegetables, and eat regular meals to maintain a balanced and healthy diet.

Correct Answer: C

Rationale: Persistent, severe abdominal pain, tenderness, and rigidity in a postpartum client can be indicative of serious conditions such as uterine rupture, hemorrhage, or infection, which require urgent medical attention. As a nurse, the priority action in this situation is to notify the healthcare provider immediately so that appropriate interventions can be initiated promptly to ensure the safety and well-being of the client. Administering analgesics or providing emotional support may not address the underlying cause of the symptoms and could potentially delay necessary medical treatment. Assisting the client to a comfortable position can be considered once the healthcare provider has been informed and appropriate assessments and interventions have been initiated.

Correct Answer: B

Rationale: The appropriate way to correct an error in the Nurses Notes is to draw a single line across the error and initial it. This method is recommended because it indicates that there was an error made, while still preserving the original information for audit and legal purposes. It shows transparency and accountability in documentation, as the original information remains visible. Taking the whole page out and replacing it with a fresh one can lead to discrepancies and potential legal issues if there are inconsistencies in the documentation. Using methods like using the sticky side of the plastic tape or a rubber eraser can make the documentation look unprofessional and raises questions about the accuracy and integrity of the notes.
