Which of the following dental conditions is characterized by the destruction of tooth structure due to exposure to acidic substances, such as gastric acid or acidic beverages?
- A. Dental caries
- B. Attrition
- C. Abrasion
- D. Erosion
Correct Answer: D
Rationale: Erosion is the dental condition characterized by the destruction of tooth structure due to exposure to acidic substances, such as gastric acid from conditions like gastroesophageal reflux disease (GERD) or acidic beverages like sodas and citrus fruits. This acidic attack softens and wears away the enamel, leading to the erosion of tooth structure. Unlike dental caries, which is caused by bacteria producing acid from sugars in the mouth, erosion is primarily a result of external acidic sources. Attrition refers to the wear of tooth structure from tooth-to-tooth contact, and abrasion refers to the wear of tooth structure due to forces like brushing too hard or using abrasive toothpaste.

After formulating and delimiting the research problem, which following will be a PRIORITY action of Gloria?
- A. Develop the theoretical framework of the study
- B. Formulate the hypothesis
- C. Plan the research design of the study
- D. Conduct a 1iterature search on the topic
Correct Answer: C
Rationale: After formulating and delimiting the research problem, the priority action would be to plan the research design of the study. This is crucial because the research design will outline the specific methods and procedures that Gloria will use to investigate the research problem and answer the research questions. Planning the research design involves determining the overall structure of the study, selecting the appropriate research methods, and outlining how data will be collected and analyzed. This step is essential for ensuring that the study is well-organized, rigorous, and will yield reliable results. Developing a solid research design early on will set a strong foundation for the rest of the research process.
Baby Sharon was placed on phototherapy. What precaution should Nurses Juvy observe?
- A. Put sunglasses on the newborn to protect his/her eyes.
- B. Be certain that the newborn's intake is adequate.
- C. Assess the newborn for symptoms of headache.
- D. Keep the newborn wrapped to prevent sunburn.
Correct Answer: A
Rationale: When a baby is placed on phototherapy, especially for treating jaundice, it is crucial for the nurses to put sunglasses on the newborn to protect their eyes. Phototherapy involves exposing the baby's skin to certain types of light to help break down the bilirubin causing the jaundice. However, this light can be harmful to the baby's sensitive eyes, potentially leading to eye damage or other eye-related issues if not protected adequately. Therefore, placing sunglasses on the newborn is a necessary precaution to ensure the safety and well-being of the baby's eyes during the treatment.
The MOST significant contributory factor to the development of lung cancer is ________.
- A. being a cigarette smoker
- B. belonging to the male sex
- C. Being extremely obese
- D. age over 4 0years
Correct Answer: A
Rationale: The most significant contributory factor to the development of lung cancer is being a cigarette smoker. Cigarette smoking is directly linked to approximately 85% of lung cancer cases. The harmful substances in tobacco smoke, such as carcinogens, damage the cells in the lungs, leading to the development of cancer over time. Smokers are at a significantly higher risk of developing lung cancer compared to non-smokers. Therefore, being a cigarette smoker is the primary and most influential risk factor for developing lung cancer.
A patient presents with chest pain that occurs at rest and is relieved by nitroglycerin. An electrocardiogram (ECG) may show transient ST-segment elevation. Which cardiovascular disorder is most likely responsible for these symptoms?
- A. Stable angina
- B. Unstable angina
- C. Acute myocardial infarction
- D. Prinzmetal's angina
Correct Answer: D
Rationale: Prinzmetal's angina, also known as variant angina, is characterized by episodes of chest pain that occur at rest and are relieved by nitroglycerin. Patients with Prinzmetal's angina may also have transient ST-segment elevation on an electrocardiogram (ECG) during episodes of chest pain. This is due to coronary artery vasospasm, which causes temporary obstruction of blood flow to the heart muscle. Stable angina typically presents with chest pain on exertion that resolves with rest, while unstable angina and acute myocardial infarction present with chest pain that is not relieved with nitroglycerin and are associated with more severe coronary artery disease.
Sandy asks the nurse if her new joint will function normally. The nurse can BEST answer this by saying that the________.
- A. doctor will be able to assess your limitations in 6 weeks and then explain them to you
- B. new joint will function almost as well as a normal joint, if you perform your exercises faithfully
- C. new joint will be stronger than the old one if you exercise well
- D. new joint won't function as well as the new joint, but will be better than the arthritic joint
Correct Answer: B
Rationale: The nurse can assure Sandy that her new joint will function almost as well as a normal joint if she performs her exercises faithfully because post-joint replacement surgery recovery often involves physical therapy and exercises aimed at restoring strength and mobility to the affected joint. By following the recommended exercise regimen and post-operative care instructions, Sandy can improve the function of her new joint and achieve a good level of mobility and functionality, similar to that of a normal joint. It is important for Sandy to be diligent and committed to her rehabilitation process to maximize the benefits of the joint replacement surgery.
