ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse is caring for a client with a peripheral vascular access device who is experiencing pain, redness, and swelling at the site. After removing the device, which action should the nurse take to relieve pain?

A. Administer topical lidocaine to the site.
B. Place warm compresses on the site.
C. . Administer prescribed oral pain medication.
D. Massage the site with scented oils.

Correct answer: B

Rationale:

2. The nurse is admitting a patient with a suspected fluid imbalance. The most sensitive indicator of body fluid balance is:

A. Daily weight
B. Serum sodium levels
C. Measured intake and output
D. Blood pressure

Correct answer: A

Rationale: Daily weight is the most sensitive indicator of body fluid balance because it can show trends over time, helping in assessing the effectiveness of interventions and medications. While serum sodium levels provide objective data on electrolyte balance, they may not accurately reflect fluid balance, especially if a patient is dehydrated. Measured intake and output are crucial for assessing fluid balance, but it can be challenging to match the two due to various ways fluid is lost from the body. Blood pressure and other vital signs may not always be reliable indicators of fluid balance as they can be influenced by other factors beyond fluid status.

3. The nurse assessing skin turgor in an elderly patient should remember that:

A. Overhydration causes the skin to tent.
B. Dehydration causes the skin to appear edematous and spongy.
C. Inelastic skin turgor is a normal part of aging.
D. Normal skin turgor is moist and boggy.

Correct answer: C

Rationale: Inelastic skin turgor is a normal part of aging. Dehydration, not overhydration, causes inelastic skin with tenting. Overhydration, not dehydration, causes the skin to appear edematous and spongy. Normal skin turgor is dry and firm. Choice A is incorrect because overhydration does not cause the skin to tent; it is dehydration that leads to tenting. Choice B is incorrect because dehydration, not overhydration, causes the skin to appear edematous and spongy. Choice D is incorrect because normal skin turgor is dry and firm, not moist and boggy.

4. What can cause dehydration?

A. Prolonged vomiting.
B. Prolonged diarrhea.
C. Too little fluid intake.
D. Prolonged vomiting, diarrhea, and too little fluid intake.

Correct answer: D

Rationale: Dehydration can result from significant fluid loss due to vomiting, diarrhea, or inadequate fluid intake. Prolonged vomiting and diarrhea lead to excessive fluid loss from the body, contributing to dehydration. Similarly, not consuming enough fluids can also result in dehydration. Choice A and B are too specific as they only mention one cause each, while choice C is also correct but does not encompass all the potential causes of dehydration as mentioned in choice D.

5. You are working on a burns unit, and one of your acutely ill patients is exhibiting signs and symptoms of third spacing. Based on this change in status, you should expect the patient to exhibit signs and symptoms of what imbalance?

A. Metabolic alkalosis
B. Hypermagnesemia
C. Hypercalcemia
D. Hypovolemia

Correct answer: D

Rationale: When a patient exhibits signs and symptoms of third-spacing, where fluid moves out of the intravascular space but not into the intracellular space, hypovolemia is expected. This leads to a decreased circulating blood volume. Increased calcium and magnesium levels are not typically associated with third-spacing fluid shift. Burns usually result in acidosis rather than alkalosis, making metabolic alkalosis an incorrect choice. Therefore, hypovolemia is the correct answer in this scenario.
