Nursing Process Questions

Correct Answer: A

Rationale: The correct size of suction catheter for James would be Fr. 5. The selection of suction catheter size is based on the patient's height and weight, as well as the secretions to be cleared. A Fr. 5 catheter is appropriate for an average adult like James, as it balances between being too small or too large. Fr. 12 and Fr. 18 are too large for his size and could cause trauma, while Fr. 10 is slightly larger than needed, increasing the risk of mucosal damage. Therefore, Fr. 5 is the most suitable choice for James.

Correct Answer: A

Rationale: The correct answer is A: Prevent clot formation. Heparin is an anticoagulant that inhibits the formation of blood clots. In DIC (Disseminated Intravascular Coagulation), there is excessive clotting throughout the body, leading to organ damage. By administering heparin, we aim to prevent further clot formation and reduce the risk of complications. Choice B is incorrect because heparin does not increase clot formation; it works to inhibit clotting. Choice C is incorrect as heparin does not directly increase blood flow to target organs. Choice D is also incorrect as heparin does not decrease blood flow to target organs; its primary role is anticoagulation.

Correct Answer: C

Rationale: Objective data are measurable and observable facts obtained through physical examination or diagnostic tests. In this case, "Respirations 16" is a quantifiable and observable measurement, making it objective data. It is not influenced by personal interpretation or feelings. The other choices, such as "States 'doesn't feel good'", "Reports a headache", and "Nauseated" are subjective data because they are based on the patient's feelings or experiences, which can vary depending on individual perception and interpretation, making them less reliable for making clinical decisions. By focusing on objective data like "Respirations 16", the nurse can provide a more accurate assessment of the patient's condition.

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: 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.
