ATI Fluid Electrolyte and Acid-Base Regulation

Correct Answer: D

Rationale: The correct answer is D: Teach the client fall prevention measures. In metabolic alkalosis, the client may experience muscle weakness and confusion, increasing the risk of falls. Teaching fall prevention measures is essential to ensure the client's safety. Monitoring hemoglobin and hematocrit values (A) is not directly related to managing metabolic alkalosis. Administering furosemide (B) is not appropriate for metabolic alkalosis. Encouraging deep breaths (C) may not address the underlying cause of the alkalosis.

Correct Answer: A

Rationale: The correct answer is A: "Avoid carrying your grandchild with the arm that has the central catheter." This is important because carrying a child can put strain on the arm where the catheter is inserted, increasing the risk of dislodging or damaging the catheter. It is crucial to protect the integrity of the catheter site to prevent complications such as infection or bleeding. Choice B is incorrect because placing the arm with the central catheter in a sling during the day is unnecessary and could restrict the client's mobility and lead to discomfort. Choice C is incorrect because flushing the PICC line with normal saline should be done by a healthcare professional and not the client themselves. Choice D is incorrect because using the arm with the central catheter for most activities of daily living can increase the risk of accidental dislodgment or damage to the catheter. It is important to be cautious and limit certain activities to protect the catheter and maintain its function.

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: Correct Answer: C - Infiltration Rationale: 1. Infiltration occurs when IV fluid leaks into surrounding tissues, causing edema. 2. Documenting infiltration is important for appropriate management. 3. Air emboli, phlebitis, and fluid overload are unrelated to edema around IV site. Summary of Incorrect Choices: A. Air emboli: This is a serious condition caused by air entering the bloodstream, not related to edema. B. Phlebitis: Inflammation of the vein, usually presenting with redness and pain, not edema. D. Fluid overload: Excess fluid volume in the body, leading to symptoms like shortness of breath, not edema.

Correct Answer: A

Rationale: The correct answer is A: Increased rate and depth of respirations. In this case, the client's arterial blood gas values show a pH within normal range (7.36), PaCO2 below normal (33 mm Hg), and HCO3 below normal (18 mEq/L), indicating a metabolic acidosis. To compensate for the acidosis, the client will hyperventilate, leading to increased rate and depth of respirations to blow off excess CO2 and attempt to normalize the pH. Options B, C, and D are incorrect because increased urinary output, thirst, hunger, and release of acids from the kidneys are not direct compensatory mechanisms for metabolic acidosis.
