ATI Fluid Electrolyte and Acid-Base Regulation

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: D

Rationale: The correct answer is D: Place a washcloth between the skin and tourniquet. This step helps protect the client's skin by providing a barrier between the tourniquet and the skin, reducing the risk of skin irritation or damage. Lowering the extremity below the heart (A) can increase venous pressure and make it harder to insert the catheter. Warm compresses (B) can dilate blood vessels and increase the risk of bruising. Tapping the skin lightly (C) can irritate the skin and is unnecessary for skin protection.

Correct Answer: D

Rationale: Rationale: Third spacing occurs when fluid shifts from the intravascular space to interstitial spaces, leading to hypovolemia. This results in decreased circulating blood volume, leading to signs of hypovolemia such as tachycardia, hypotension, and low urine output. Metabolic alkalosis, hypermagnesemia, and hypercalcemia are not directly related to third spacing and are not the expected imbalances in this scenario.

Correct Answer: C

Rationale: Correct Answer: C Rationale: Asking the patient about allergies to latex or iodine is crucial before starting the IV insertion process. This step ensures patient safety and prevents potential allergic reactions. Knowing the patient's allergies allows the nurse to select appropriate materials for the procedure, reducing the risk of complications. Summary of Other Choices: A: Leaving one hand ungloved is not recommended as it compromises infection control practices. B: Cleansing the skin with normal saline is important but should come after confirming allergies to latex or iodine. D: Removing excessive hair from the site is unnecessary and not a standard practice for starting the IV insertion process.

Correct Answer: D

Rationale: The correct answer is D: Excessive administration of chloride. Normal anion gap acidosis is commonly caused by an excessive intake of chloride-containing solutions like normal saline during treatment. This leads to an increase in the plasma chloride concentration, causing a decrease in the anion gap. Metastases (A) are not typically associated with normal anion gap acidosis. Excessive potassium intake (B) would not lead to normal anion gap acidosis but rather hyperkalemia. Water intoxication (C) can lead to dilutional hyponatremia but not normal anion gap acidosis.
