Which of the following dental conditions is characterized by the abnormal wearing away of tooth structure due to factors such as bruxism or acidic erosion?

Correct Answer: B

Rationale: Attrition is the dental condition characterized by the abnormal wearing away of tooth structure due to factors such as bruxism (grinding or clenching of teeth) or acidic erosion. Bruxism can cause tooth-to-tooth contact that leads to the wearing down of the tooth enamel and eventually can affect deeper layers of the tooth. Acidic erosion, on the other hand, is caused by the direct contact of teeth with acidic substances, which can lead to the gradual loss of tooth structure over time. Dental caries refers to tooth decay caused by bacteria, abrasion involves wearing away of tooth structure due to external factors like improper brushing habits, and erosion specifically relates to the loss of tooth structure caused by acidic substances.

Correct Answer: B

Rationale: When a patient receiving palliative care for end-stage COPD expresses a desire to discuss advance care planning, the palliative nurse should initiate a conversation about advance directives and future care preferences. Advance care planning involves discussing and documenting a patient's preferences regarding future medical care, particularly in situations where the patient may no longer be able to make decisions. This discussion helps ensure that the patient's wishes are respected and followed in the event they are unable to communicate their preferences. By engaging in advance care planning discussions, the nurse can help the patient feel empowered, supported, and in control of their medical care decisions. It also allows healthcare providers to align care with the patient's values and goals, ultimately improving quality of life and ensuring dignity at the end of life.

Correct Answer: B

Rationale: When a patient arrives in the emergency room, the nurse's first priority is to assess the patient's airway, breathing, and circulation, following the ABCs of emergency care. In this scenario, positioning the patient with the head lower than the extremities ensures proper blood flow to vital organs, especially the brain. This position helps to maintain perfusion to the brain and prevent complications such as hypotension and shock. Once the patient's position is optimized, the nurse can proceed with further interventions such as starting an intravenous line, stopping bleeding, and requesting laboratory examinations as needed.

Correct Answer: A

Rationale: Two of the 8 Millennium Development Goals that are very specific to Maternal and Child Health (MCH) are "Reduce child mortality" and "Improve maternal health." These goals focus directly on the well-being of mothers and children, aiming to decrease child mortality rates and enhance the health of pregnant women.

Correct Answer: B

Rationale: The patient's presentation of severe headache, blurred vision, and fatigue, along with the laboratory findings of elevated white blood cell count, thrombocytosis, and JAK2 V617F mutation, are characteristic of essential thrombocythemia. This is a myeloproliferative neoplasm characterized by the clonal proliferation of megakaryocytes, leading to an increased platelet count. The JAK2 V617F mutation is commonly found in essential thrombocythemia and other myeloproliferative disorders. The symptoms of essential thrombocythemia can be related to the increased blood viscosity and risk of thrombosis due to the elevated platelet count. Polycythemia vera would present with elevated red blood cell count, hemoglobin, and hematocrit, along with other features such as pruritus after a hot bath. Chronic myeloid leukemia (CML

Correct Answer: B

Rationale: Disseminated intravascular coagulation (DIC) is a condition characterized by widespread activation of coagulation leading to both thrombosis and hemorrhage. In patients with chronic liver disease, especially in the setting of advanced cirrhosis, DIC can develop due to factors such as decreased synthesis of coagulation factors and impaired clearance of activated clotting factors. The patient in this scenario presents with signs of both abnormal bleeding (bruising, petechiae, mucosal bleeding) and laboratory findings consistent with DIC, including prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT) along with decreased platelet count.

Correct Answer: D

Rationale: Respect for persons is an ethical principle that emphasizes the autonomy and freedom of individuals to make their own decisions regarding participation in research studies. In the context of human subjects research, this principle requires that individuals have the right to choose whether or not to participate in a study, without any coercion or manipulation. The principle of respect for persons also includes the concept of informed consent, where individuals must be provided with all necessary information about the study in order to make an informed decision about participation. Overall, respecting the autonomy and choices of individuals is a fundamental aspect of ethical research conduct.

Correct Answer: A

Rationale: Immersing oneself in the local community and participating in their everyday activities allows the nurse, as a community organizer, to establish trust and build rapport with the people. By actively engaging with the community members, the nurse can show genuine interest and commitment to their well-being, which fosters a sense of connection and mutual understanding. This approach is crucial for gaining the trust of the community, as it demonstrates that the nurse is invested in listening to their needs and working together to address health concerns effectively.

Correct Answer: B

Rationale: Negligence refers to the failure to act or perform duties according to the standard of care expected from a reasonable person in similar circumstances. In this case, Nurse Lina administering a penicillin injection that was ordered for another patient is a clear instance of negligence. It involves a breach of duty by not verifying the correct patient and medication before administration. While malpractice can also encompass negligence, it typically involves a broader scope of professional misconduct or harm caused by a healthcare provider. Assault and battery involve intentional harmful acts, which are not applicable in this situation.
