Nursing Process Questions

Correct Answer: D

Rationale: The correct answer is D: Malnutrition. Malnutrition weakens the immune system, making individuals more susceptible to contracting tuberculosis. A well-nourished individual has a stronger immune response to fight off TB bacteria. Exposure to toxic gases (A), congenital abnormalities (B), and obstruction by tumor (C) do not directly predispose a client to TB. Malnutrition is the key factor as it impairs the immune system's ability to combat the TB bacteria effectively.

Correct Answer: C

Rationale: The correct answer is C because in the humoral immune response, B cells are stimulated by T helper cells or macrophages to differentiate into plasma cells that produce antibodies or memory cells. This process involves the production of specific antibodies that target the foreign antigen. Choice A is incorrect because B cells do not phagocytize antigens; instead, they produce antibodies. Choice B is incorrect because T cells do not turn into plasma cells. It is the B cells that differentiate into plasma cells in the humoral immune response. Choice D is incorrect because T cells do not produce antibodies. T cells are involved in cell-mediated immunity, not the humoral immune response.

Correct Answer: C

Rationale: Objective data in nursing refers to measurable and observable information. Respirations at 16 per minute are a specific, quantifiable measurement that the nurse can directly observe, making it objective data. This information is vital for assessing the patient's respiratory status accurately. Choice A is incorrect because stating "doesn't feel good" is a subjective statement based on the patient's perception and cannot be directly measured or observed. Choice B, reporting a headache, is also subjective as it relies on the patient's description of their symptoms. Choice D, being nauseated, is subjective as well, as it is a symptom reported by the patient and not a quantifiable measurement. In summary, choice C is correct as it represents objective data due to its quantifiable and observable nature, while the other choices are subjective and based on the patient's perceptions or feelings.

Correct Answer: C

Rationale: Objective data are measurable and observable facts. Respirations (C) of 16 per minute is objective data as it is a quantifiable measurement that can be counted and recorded. It is not influenced by personal interpretation or bias. Choices A, B, and D are subjective data as they rely on the patient's feelings, perceptions, or symptoms, which can vary and are open to interpretation. Therefore, choice C is the correct answer as it represents concrete, verifiable information that can be used in the patient's assessment and care planning.

Correct Answer: A

Rationale: Correct Answer: A: Respiratory acidosis Rationale: 1. Respiratory acidosis is caused by inadequate ventilation leading to increased PCO? and decreased pH. 2. Low pH indicates acidosis, and high PCO? indicates respiratory component. 3. Metabolic acidosis (B) results from non-respiratory causes. 4. Respiratory alkalosis (C) is characterized by high pH and low PCO?. 5. Metabolic alkalosis (D) is caused by non-respiratory factors with high pH.
