What is the purpose of a chest tube after a lobectomy procedure, as understood by the nurse?

Correct Answer: C

Rationale: After a lobectomy, a chest tube is typically inserted to drain fluids and blood that may have accumulated post-operatively. This tube helps to prevent complications, such as infections or pneumonia, and aids in patient recovery. While a chest tube may aid in preventing a mediastinal shift (Choice A), promoting chest expansion of the remaining lung (Choice B), and removing air in the lungs to promote lung expansion (Choice D), these are not the primary reasons for its use after a lobectomy. Therefore, Choices A, B, and D are incorrect.

Correct Answer: A

Rationale: The primary objective when dealing with cases of child abuse is to ensure the safety of the child and any siblings. This means creating a secure environment free from harm, which is why choice 'A' is the correct answer. While choices 'B', 'C', and 'D' might be subsequent steps in a comprehensive plan to deal with the situation, they are not the immediate priority. Understanding abusive behavioral patterns or improving the relationship with the counselor will not directly lead to the child's safety. Likewise, teaching the mother to apply verbal discipline doesn't guarantee the child's safety if the abusive behavior continues. Therefore, these options are not the most important initial goal.

Correct Answer: C

Rationale: The correct answer is C. While it is true that Mrs. Guevarra is delegating tasks to the nurse-aide, she does not necessarily have to directly supervise or evaluate the aide. She still retains the overall accountability for the care of the client, but direct supervision of the aide is not a requirement for delegation. Choice A is incorrect because the primary purpose of delegation is not instruction. Choice B is also incorrect because although Mrs. Guevarra is delegating tasks, she still retains accountability for those tasks. Finally, choice D is incorrect because the ability to perform the task being delegated is not a requirement for the delegator; the delegatee should have the necessary skills and knowledge to perform the delegated tasks.

Correct Answer: A

Rationale: The correct answer is A, which directs the client to avoid foods such as smoked meats and frozen dinners. These types of foods are typically high in sodium, making them unsuitable for a low-sodium diet. Option B is incorrect because foods with less than 4g of sodium might still be high in sodium for individuals on low-sodium diets. The daily recommended intake of sodium for a low-sodium diet is usually around 1.5g to 2g. Hence, 4g of sodium in a single food product can be excessive. Option C is incorrect as soy sauce, although a different source of flavor, is also high in sodium and should be used sparingly, if at all, in a low-sodium diet. Option D is incorrect because processed and prepared foods are usually not low in sodium. In fact, these foods often have high sodium content due to added salts and preservatives.

Correct Answer: C

Rationale: The correct term for the beliefs, ideals, and values that direct an organization and provide it with a sense of purpose is 'Vision'. A Vision statement outlines the organization's aspirations and goals for the future. Choices A, B, and D are incorrect in this context. 'Philosophy' refers to a system of beliefs or principles, 'Mission' relates to the organization's purpose and primary objectives, and 'Goals and Objectives' are the specific targets set to accomplish the Vision.

Correct Answer: A

Rationale: Following colostomy surgery, a healthy stoma should appear pink, moist, and slightly protruding from the abdomen, which is why option 'A' is the correct answer. A gray stoma (choice 'B') could indicate poor blood supply or necrosis, which is a serious complication. A dry stoma (choice 'C') is also not normal as it should be moist; a dry stoma may suggest dehydration or other complications. While a stoma can appear red (choice 'D'), this is not typically the normal color; it should usually be pink. Therefore, it's important for healthcare professionals to correctly identify the normal and abnormal appearances of a stoma to ensure proper patient care.

Correct Answer: C

Rationale: The QRS Complex in an ECG reading represents ventricular depolarization, which is the process of the heart's ventricles preparing to contract by changing the electrical charge in the cell, hence choice 'C' is the correct answer. Choice 'A' is incorrect because atrial depolarization is represented by the P wave in an ECG reading, not the QRS Complex. Choice 'B' is incorrect as ventricular repolarization is depicted by the T wave, not the QRS Complex. Finally, choice 'D' is also incorrect because the QRS Complex is not the end of ventricular depolarization, but the process itself.

Correct Answer: A

Rationale: The correct answer is 'A', which says trim nails using a nail clipper. This is incorrect because patients with peripheral vascular disease, particularly those caused by diabetes, should not trim their nails themselves due to the risk of injury, infection, and poor wound healing. The other options, 'B', 'C', and 'D', are correct advice for diabetic foot care. Applying cornstarch can help keep the feet dry and prevent fungal infections. Checking the water temperature before bathing can prevent burns, as patients with peripheral vascular disease often have decreased sensation in their feet. Wearing canvas shoes can improve foot ventilation and reduce the risk of foot ulcers and infections.

Correct Answer: C

Rationale: Common risk factors for lifestyle-related diseases typically include aspects of one's lifestyle that can be modified or controlled, such as physical activity, smoking habits, and nutrition. These factors can be changed to prevent or manage lifestyle-related diseases. Genetics, on the other hand, is not a modifiable risk factor, meaning it cannot be changed or controlled. Therefore, it is not considered a common risk factor for lifestyle-related diseases. Understanding the modifiable risk factors for these diseases allows for better prevention and management strategies, and helps reduce the risk of complications.
