Client perceptions about their health problems are:
- A. Objective data
- B. Observational recordings
- C. Aucilliary reports from the data collector
- D. Subjective data
Correct Answer: D
Rationale: Subjective data are clients' perceptions e.g., 'I feel dizzy' reported directly, capturing experiences unmeasurable by others. This contrasts with objective data (e.g., pulse), observable by nurses. Observational recordings are objective, like noting pallor, not perceptions. Ancillary reports (e.g., lab results) are objective, external data, not client-voiced. Subjective data's focus on personal input e.g., pain severity enriches assessment, guiding nurses to explore symptoms' impact (e.g., anxiety's role), making it vital for holistic care and the correct classification here.
A client with hypothyroidism is being taught about dietary management. Which statement by the client indicates an understanding of the teaching?
- A. I should increase my intake of iodine-rich foods.
- B. I should decrease my intake of iodine-rich foods.
- C. I should increase my intake of potassium-rich foods.
- D. I should decrease my intake of sodium-rich foods.
Correct Answer: A
Rationale: The correct answer is A. Increasing intake of iodine-rich foods is beneficial for clients with hypothyroidism as iodine is essential for thyroid hormone synthesis. Adequate iodine intake helps to support thyroid function in individuals with hypothyroidism, making choice A the most appropriate response indicating an understanding of the dietary management for this condition. Choices B, C, and D are incorrect because decreasing iodine-rich foods, increasing potassium-rich foods, or decreasing sodium-rich foods are not the recommended dietary modifications for hypothyroidism. In fact, decreasing iodine-rich foods could exacerbate hypothyroidism due to the essential role of iodine in thyroid hormone production.
A group of nursing students has attended a presentation about the National Student Nurses' Association (NSNA). Which statement by the group indicates that they have understood the information presented?
- A. The NSNA contributes to the improvement of public health
- B. The organization provides programs of current professional interest
- C. It is run by a group of registered nurses
- D. It is funded by the national government
Correct Answer: B
Rationale: The National Student Nurses' Association (NSNA) is a student-led organization designed to support nursing students' professional development, and understanding its purpose is key for students. The correct statement, that it provides programs of current professional interest, reflects its role in offering educational events, leadership opportunities, and resources tailored to students' needs, preparing them for their future careers. The NSNA does not primarily focus on improving public health, which is more aligned with bodies like the Commission on Collegiate Nursing Education. It is not run by registered nurses but by students themselves, emphasizing peer leadership and engagement. Additionally, it is student-funded through membership dues, not supported by the national government. This distinction highlights the NSNA's unique position as a grassroots organization fostering professional growth, networking, and advocacy among nursing students, ensuring they are well-equipped to enter the profession with relevant skills and knowledge.
The nurse is preparing to administer regular insulin to a client with type 1 diabetes. Before administering the insulin, the nurse should:
- A. Rotate the vial between her hands
- B. Warm the insulin to body temperature
- C. Shake the vial vigorously
- D. Draw up the insulin with an 18-gauge needle
Correct Answer: A
Rationale: Rotating the vial between hands mixes regular insulin gently, ensuring even suspension without denaturing it warming, shaking, or large needles risk potency loss or tissue damage. Nurses use this technique, confirming clarity, for safe, effective glycemic control in type 1 diabetes.
