Correct Answer: A

Rationale: The correct answer is A: Etiology. Etiology in a nursing diagnosis refers to the cause or contributing factors of the identified problem. In this case, the large scar over the left side of the face is the reason for the disturbed self-esteem. It is the underlying factor that is leading to the self-esteem issue. The problem itself is the disturbed self-esteem, the defining characteristics are the signs and symptoms that support the diagnosis, and client need is the desired outcome or goal for the client. In summary, the presence of the large scar is the cause or etiology of the disturbed self-esteem, making it the correct choice.

Correct Answer: C

Rationale: The correct answer is C: Observing for leakage of urine or stool from the anastomosis. This is crucial in nursing management post-urinary diversion procedure to prevent complications such as infection, dehydration, and skin breakdown. Leakage can indicate issues with the surgical site integrity and requires prompt intervention. A: Placement of IV and central venous pressure lines is important but not as critical as monitoring for leakage from the anastomosis. B: Administering cleansing enemas may be necessary for certain procedures but is not the most important factor in this case. D: Assessing the client's ability to manage self-catheterization is important for long-term care but does not take precedence over monitoring for potential complications like leakage. In summary, option C is the most important factor as it directly impacts the client's immediate post-operative care and helps prevent serious complications.

Correct Answer: A

Rationale: The correct answer is A: It is associated with stages 1 and 2 hypertension. Smoking is a major risk factor for developing hypertension, especially stages 1 and 2. Nicotine in cigarettes can lead to vasoconstriction, increased heart rate, and overall elevated blood pressure. This information is crucial for patients to understand the direct impact of smoking on their blood pressure levels. Choice B is incorrect because smoking does indeed affect BP regulation by causing vasoconstriction and elevated heart rate. Choice C is incorrect as smoking actually causes vasoconstriction rather than vasodilation. Choice D is incorrect because smoking does lead to sustained elevation of blood pressure, especially in the long term.

Correct Answer: D

Rationale: The correct answer is D: "I will have my potassium level checked." Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. A: Monitoring urine sodium is not typically necessary for furosemide therapy. B: Prothrombin time monitoring is unrelated to furosemide therapy. C: Monitoring calcium levels is not directly affected by furosemide use. In summary, monitoring potassium levels is essential due to the potential for hypokalemia with furosemide, while the other options are not directly relevant to this medication.

Correct Answer: D

Rationale: The correct answer is D, the Western blot test with ELISA. First, ELISA is used as a screening test for HIV antibodies. If positive, a confirmatory test like Western blot is needed to detect specific antibodies. Western blot is highly specific and confirms the presence of HIV antibodies. E-rosette immunofluorescence is not typically used for HIV diagnosis. Quantification of T-lymphocytes is used to monitor disease progression in HIV but does not confirm HIV infection. ELISA alone is not confirmatory; it needs to be followed by a more specific test like Western blot.
