Nursing Process Practice Questions

Correct Answer: C

Rationale: Rationale: Choice C is correct because antibodies are indeed produced by B-cells as part of the adaptive immune response. B-cells differentiate into plasma cells that produce antibodies to target specific antigens. This process is essential for generating immunity against pathogens. Incorrect Choices: A: Antibody-mediated defense occurs through the B-cell system, not the T-cell system. T-cells are involved in cell-mediated immunity. B: Cellular immunity is mediated by T-cells, not antibodies produced by B-cells. T-cells directly attack infected cells. D: Lymphocytes can increase during an allergic response, but this does not specifically relate to immunity through antibody production by B-cells.

Correct Answer: A

Rationale: The correct answer is A because a positive diagnosis for HIV infection is confirmed through laboratory testing, specifically the ELISA and Western blot tests. These tests detect the presence of HIV antibodies in the blood, providing definitive evidence of the infection. Choice B is incorrect as weight loss and fever are symptoms but not diagnostic criteria. Choice C is incorrect as opportunistic infections are a consequence of HIV, not the diagnostic criteria. Choice D is incomplete and irrelevant. In summary, the key to diagnosing HIV is through positive laboratory tests, not just based on symptoms or associated infections.

Correct Answer: C

Rationale: The correct answer is C: Lean red meats. Lean red meats are a rich source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Heme iron helps improve iron levels more effectively in individuals with iron deficiency anemia. Fresh fruits (A) and dairy products (B) contain minimal iron, while breads and cereals (D) provide non-heme iron which is not as readily absorbed.

Correct Answer: B

Rationale: The correct answer is B because providing frequent mouth care to Mr. Franco helps in removing dried blood when his tongue is bitten during a seizure, preventing infection and promoting oral hygiene. This is crucial in preventing complications and ensuring Mr. Franco's overall well-being. Choice A is incorrect because thirst is not directly related to mouth care, and increasing fluids intake would address dehydration more effectively. Choice C is incorrect as tactile stimulation may not necessarily hasten return to consciousness in this context. Choice D is incorrect as it refers to a different issue related to mouth breathing in comatose patients, which is not the immediate concern addressed by frequent mouth care in this scenario.

Correct Answer: D

Rationale: The correct answer is D because developing a standard formal nursing diagnosis helps nurses focus on the scope of their practice. By identifying specific patient problems and their potential causes, nurses can provide appropriate interventions and evaluate patient outcomes effectively. This process enhances the quality of care delivery and promotes patient safety. A: This is incorrect because nursing diagnoses are not meant to be a language exclusive to nurses but rather a standardized way to communicate patient data. B: This is incorrect as nursing diagnoses are not about distinguishing roles but rather about identifying and addressing patient problems. C: This is incorrect as nursing diagnoses are based on evidence and critical thinking, not solely on intuition.
