ATI Fluid Electrolyte and Acid-Base Regulation

Correct Answer: C

Rationale: The correct answer is C because it includes foods high in potassium. Raisins, whole wheat toast, and milk are good sources of potassium. Sausage might contain some potassium as well. A: This option lacks potassium-rich foods. B: While strawberries have some potassium, the overall meal lacks a sufficient amount. D: While oatmeal and peaches have potassium, coffee can actually inhibit potassium absorption.

Correct Answer: D

Rationale: The correct answer is D because dangling the client on the bedside before ambulating helps prevent orthostatic hypotension and potential falls. This step allows the nurse to assess the client's tolerance to changes in position and reduces the risk of injury. A: Asking family members to speak quietly does not directly address the prevention of injury related to dehydration. B: Assessing urine parameters is important for monitoring hydration status but does not directly prevent injury. C: Encouraging fluid intake is important for rehydration but does not directly address the risk of injury during ambulation.

Correct Answer: C

Rationale: The correct answer is C. Reading food labels to determine sodium content is important in managing mild hypernatremia. This allows the client to monitor and control their sodium intake, which can help prevent further elevation of sodium levels. Weighing oneself or checking the pulse does not directly address sodium intake. Choosing cooking methods like baking or grilling is more about reducing fat intake, not sodium.

Correct Answer: A

Rationale: The correct answer is A: Cardiac rate and rhythm. In an acid-base imbalance, the pH is below the normal range indicating acidosis. The nurse should assess the cardiac rate and rhythm first because acidosis can have negative effects on the cardiovascular system. Acidosis can lead to arrhythmias and decreased cardiac output. Monitoring the cardiac rate and rhythm is crucial to detect any cardiac complications early. Choices B, C, and D are not the priority in this situation as they are not directly impacted by acid-base imbalances.

Correct Answer: A

Rationale: The correct answer is A: Assess the airway. The nurse should prioritize airway assessment as the client's ABGs indicate respiratory acidosis (low pH, high PaCO2). This suggests potential airway obstruction or inadequate ventilation. Ensuring a patent airway is crucial for adequate oxygenation. Administering bronchodilators (B) or mucolytics (D) may help with airway clearance but should come after ensuring a clear airway. Providing oxygen (C) is important, but addressing the underlying respiratory acidosis by first assessing the airway is the priority in this situation to prevent further deterioration.
