Correct Answer: C

Rationale: Correct Answer: C - Administer IV fluids Rationale: 1. Assess patient's fluid status and hydration level. 2. IV fluids help maintain adequate hydration during hemodialysis. 3. Prevents hypotension and ensures stable blood pressure during the procedure. 4. Improves overall hemodialysis efficiency and patient safety. Summary: A: Checking patency is important, but not the primary intervention for hemodialysis. B: Monitoring for bleeding is crucial but not specific to AVF assessment. D: Applying an airtight dressing is not necessary for AVF assessment.

Correct Answer: A

Rationale: The correct answer is A: Blood pressure measurement. Dizziness and weakness can be symptoms of hypotension or low blood pressure. Prioritizing blood pressure measurement is crucial because it can indicate if the patient is at risk of complications like cardiovascular collapse. Pulse oximetry (B) is important for assessing oxygen levels in the blood but may not directly address dizziness and weakness. Blood glucose levels (C) are important but not the priority in this scenario. Cardiac monitoring (D) may be necessary but should come after assessing blood pressure to rule out immediate life-threatening conditions.

Correct Answer: D

Rationale: The correct answer is D, perform a lumbar puncture. A positive Brudzinski sign indicates meningeal irritation, a hallmark of meningitis. A lumbar puncture is the gold standard for diagnosing meningitis by analyzing cerebrospinal fluid. Placing the client on their back without proper diagnosis or treatment delays could lead to serious complications. Option B is incorrect as antibiotics should be given after confirming the diagnosis. Option C is partially correct but does not address the need for a definitive diagnostic test. Option A is incorrect as pain medication alone does not address the underlying cause of meningitis.

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: C

Rationale: The correct answer is C: sodium and chloride. In the extracellular fluid, sodium and chloride are the major electrolytes due to their roles in maintaining fluid balance, nerve function, and muscle contraction. Potassium and phosphate (choice B) are primarily found in intracellular fluid, while potassium and chloride (choice A) are not the major electrolytes in extracellular fluid. Similarly, sodium and phosphate (choice D) are not major extracellular electrolytes. Thus, choice C is the correct answer based on the significant presence and functions of sodium and chloride in the extracellular fluid.
