Question 1 of 5

What is the primary purpose of using measurable client outcomes during the nursing process?

Correct Answer: B

Rationale: The primary purpose of using measurable client outcomes during the nursing process is to evaluate the effectiveness of nursing interventions. This is crucial in determining whether the care provided has led to the desired outcomes for the client's health. By measuring outcomes, nurses can assess if the interventions are successful, make any necessary adjustments to the care plan, and ensure optimal patient outcomes. Choice A is incorrect because diagnosing client conditions accurately is not the primary purpose of using measurable client outcomes; it is more related to the initial assessment phase. Choice C is incorrect because prioritizing nursing diagnoses effectively is an important aspect of the nursing process, but it is not the primary purpose of using measurable client outcomes. Choice D is incorrect because while documentation in the client's health record is important, it is not the primary purpose of using measurable client outcomes.

Question 2 of 5

Which of the ff values pertaining to different clients shows the normal range of plasma pH?

Correct Answer: A

Rationale: The correct answer is A: 7.35-7.45. Plasma pH typically falls within this range for normal clients. A pH of 7.35-7.45 indicates a slightly alkaline to neutral environment, which is essential for various physiological processes to function optimally. Choices B, C, and D have pH values outside the normal range, indicating either acidic (B and C) or highly alkaline (D) conditions, which would be abnormal and potentially harmful to the body's functioning. Therefore, the normal range for plasma pH is crucial to maintain homeostasis and support overall health.

Question 3 of 5

A patient who is being tested for HIV asks what tests are used. The nurse would correct in stating that the tests used to confirm HIV infection are which of the following?

Correct Answer: B

Rationale: The correct answer is B: ELISA and Western Blot. The rationale is as follows: ELISA (enzyme-linked immunosorbent assay) and Western Blot are specific tests used to confirm HIV infection by detecting antibodies or antigens related to the virus. ELISA is the initial screening test, while Western Blot is the confirmatory test. These tests are highly sensitive and specific for HIV detection. Choice A is incorrect because CD4+ cell count and thymus function are not tests used to confirm HIV infection. They are used to monitor disease progression and immune function in HIV-positive individuals. Choice C is incorrect because B-cell and T-cell count are also not tests used to confirm HIV infection. They are indicators of immune system health but not specific for HIV diagnosis. Choice D is incorrect because while CD4+ and viral load tests are used in monitoring HIV progression, ELISA is the main confirmatory test for HIV diagnosis, and viral load is not typically used for initial

Question 4 of 5

The nurse is aware that the shift of body fluids associated with the intravenous administration of albumin occurs by the process of:

Correct Answer: A

Rationale: The correct answer is A: Filtration. Albumin is a large protein molecule that cannot pass through the semipermeable membrane of blood vessels. Therefore, the shift of body fluids associated with intravenous albumin administration occurs through the process of filtration, where fluid moves across the membrane due to a pressure difference. Osmosis (B) involves the movement of water across a semipermeable membrane, which is not the case for albumin. Diffusion (C) is the movement of molecules from an area of high concentration to low concentration, which is not how albumin moves. Active transport (D) requires energy to move substances against a concentration gradient, which is not the mechanism for albumin movement in the body.

Question 5 of 5

Which vein should be used first when initiating IV therapy?

Correct Answer: B

Rationale: The correct answer is B: Basilic vein. It is preferred for IV therapy due to its size, accessibility, and lower risk of complications. Basilic vein is deep and stable, aiding in successful catheter insertion and reduced risk of infiltration. Jugular vein (A) is not typically used due to the high risk of complications like infection. Brachiocephalic (C) and Axillary (D) veins are less commonly used as they are smaller and more prone to complications compared to the Basilic vein. In summary, the Basilic vein is the optimal choice for initiating IV therapy due to its size, accessibility, stability, and lower risk of complications.
