The nurse is instructed to perform preoperative preparation for the management of a client with malignant tumors. Which of the ff is the most important factor of the nursing management plan?

Correct Answer: C

Rationale: The correct answer is C: Maintaining the integrity of the urinary system. This is crucial in preoperative preparation for a client with malignant tumors to prevent complications such as urinary obstruction or infection. Assessing symptoms of peritonitis (B) is important but not as critical as ensuring urinary system integrity. Insertion of an ostomy pouch (A) and nasogastric tube diversion procedure (D) may be necessary interventions for some cases, but they are not as essential as ensuring the urinary system's integrity to prevent serious complications.

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.

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.

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.

Correct Answer: B

Rationale: The correct answer is B: To prevent respiratory obstruction. An ice collar is used to reduce swelling and inflammation, which can help prevent the abscess from compressing the airway and causing respiratory obstruction. This is crucial in cases of peritonsillar abscess to ensure the client's airway remains patent. Choices A, C, and D do not directly address the primary concern of preventing respiratory obstruction in this context.
