Nursing Process Questions

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: D

Rationale: The correct answer is D: Impaired gas exchange related to alveolar-capillary membrane changes. This nursing diagnosis is appropriate for a patient with pneumonia and lower lobe infiltrates as it directly addresses the underlying physiological issue of impaired gas exchange due to alveolar-capillary membrane changes. The infiltrates indicate infection and inflammation in the lower lobes, leading to difficulty in oxygen and carbon dioxide exchange. This diagnosis aligns with the patient's medical condition and helps guide nursing interventions focused on improving oxygenation. Choice A is incorrect because ineffective breathing pattern is a broad diagnosis that does not specifically address the gas exchange issue seen in pneumonia. Choice B is incorrect as the risk for infection is already present with the diagnosis of pneumonia and does not directly address the patient's current respiratory status. Choice C is incorrect as dehydration is not the primary concern in a patient with pneumonia and lower lobe infiltrates.

Correct Answer: B

Rationale: The correct answer is B because it addresses the importance of notifying the physician about a painless lump at the top of the chest incision, which could indicate a serious complication like a seroma or hematoma. This is crucial for early detection and intervention. A is incorrect because showers are generally allowed after cardiac surgery as long as the incisions are kept clean and dry. C is incorrect because support hose or elastic stockings are typically recommended to be worn during the day and removed at night to prevent swelling and promote circulation. D is incorrect because resuming sexual relations after cardiac surgery should be based on individual recovery and should be discussed with the healthcare provider, rather than a standard timeframe.

Correct Answer: A

Rationale: The correct answer is A: Inspecting for bleeding or cyanosis. During uterosigmoidostomy, the nurse's critical task is to monitor for any signs of bleeding or cyanosis, which are indicators of potential complications such as hemorrhage or impaired blood flow. This involves observing the surgical site for any abnormal bleeding and assessing the skin color for signs of inadequate oxygenation. Inspecting for symptoms of peritonitis (B) is not directly related to this surgical procedure. Assessing the client's allergy to iodine (C) is important but not a critical task during the procedure. Checking for signs of electrolyte losses (D) is important but not as critical as monitoring for immediate postoperative complications like bleeding or cyanosis.

Correct Answer: A

Rationale: The correct answer is A because it accurately describes the procedure of bronchoscopy. The nurse's explanation should focus on the insertion of a small tube through the nose or mouth into the bronchi to visualize the airways. This information helps the patient understand the basic process and what to expect during the procedure. Choice B is incorrect as bronchoscopy does not involve breathing a radioactive substance to show diseased areas in the lungs. Choice C is also incorrect as there is no requirement to drink a thick white liquid for bronchoscopy. Choice D is incorrect as dye injection is not a standard part of bronchoscopy, and asking about allergies to dye is irrelevant in this context.
