Correct Answer: B

Rationale: The correct answer is B: Monitor for signs of infection. Within the first 48 hours post-op, fever is often indicative of an infection. Monitoring for signs such as increased pain, redness, swelling, warmth at the surgical site, elevated white blood cell count, and changes in vital signs helps in early detection and prompt treatment of infections. Administering antipyretics (choice A) may help reduce fever but does not address the underlying cause. Administering fluids (choice C) is important for hydration but does not directly address the fever's cause. Performing an abdominal assessment (choice D) is not specific to addressing fever in a post-op client.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. Peritonitis is an inflammation of the peritoneum often caused by infection. Administering antibiotics is crucial to combat the infection. It is important to treat the underlying cause first before focusing on symptom management. Administering analgesics (B) may provide temporary relief but won't address the infection. Applying an ice pack (C) is not appropriate for peritonitis as it won't treat the infection. Performing a laparotomy (D) is a surgical procedure that may be necessary in severe cases but is not the initial nursing action.

Correct Answer: A

Rationale: The correct answer is A: Inspect for visible pulsation. This is because an arteriovenous fistula for hemodialysis should have a visible pulsation, indicating proper blood flow. Palpating for thrill (B) and auscultating for bruit (C) are also common assessments for an arteriovenous fistula, but inspecting for visible pulsation is the most direct and reliable way to assess the patency of the fistula. Percussing for dullness (D) is not relevant in this context as it does not provide information about the vascular access site.

Correct Answer: A

Rationale: The correct answer is A: Check for signs of infection. This is crucial because chemotherapy weakens the immune system, increasing the risk of infections. Signs of infection such as fever, chills, sore throat, and cough should be closely monitored to prevent serious complications. Monitoring weight (B) and nutrition (C) are important but not as critical as detecting infections promptly. Checking for skin changes (D) is also important, but it is secondary to identifying and managing infections due to the immediate threat they pose to the client's health.

Correct Answer: C

Rationale: The correct quadrant for tenderness in suspected appendicitis is the lower right quadrant (Choice C). This is because the appendix is located in the lower right abdomen. Appendicitis typically presents with pain starting around the navel and then localizing to the lower right quadrant. The other choices, upper right (Choice A), upper left (Choice B), and lower left (Choice D) are incorrect as they do not correspond to the typical location of the appendix. Upper right quadrant is where the liver and gallbladder are situated, upper left quadrant contains the stomach and spleen, and lower left quadrant has the colon and left ovary/testis.
