ATI Fluid Electrolyte and Acid-Base Regulation

1. The nurse caring for a patient post colon resection is assessing the patient on the second postoperative day. The nasogastric tube (NG) remains patent and continues at low intermittent wall suction. The IV is patent and infusing at 125 mL/hr. The patient reports pain at the incision site rated at a 3 on a 0-to-10 rating scale. During your initial shift assessment, the patient complains of cramps in her legs and a tingling sensation in her feet. Your assessment indicates decreased deep tendon reflexes (DTRs) and you suspect the patient has hypokalemia. What other sign or symptom would you expect this patient to exhibit

A. Diarrhea
B. Dilute urine
C. Increased muscle tone
D. Joint pain

Correct answer: B

Rationale:

2. A nurse is caring for an older adult client who is admitted with moderate dehydration. Which intervention should the nurse implement to prevent injury while in the hospital?

A. Ask family members to speak quietly to keep the client calm.
B. Assess urine color, amount, and specific gravity each day.
C. Encourage the client to drink at least 1 liter of fluids each shift.
D. Dangle the client on the bedside before ambulating.

Correct answer: D

Rationale: The correct answer is to 'dangle the client on the bedside before ambulating.' This intervention helps prevent orthostatic hypotension, a drop in blood pressure when changing positions, which is crucial in preventing falls and related injuries in older adult clients. Asking family members to speak quietly (Choice A) may help keep the client calm but does not directly address the risk of injury. Assessing urine parameters (Choice B) is important for monitoring hydration status but does not specifically prevent injury. Encouraging increased fluid intake (Choice C) is essential for managing dehydration but does not directly address the risk of injury during ambulation.

3. The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?

A. Choose a site with minimal hair if available.
B. Consider potential effects on the patient's mobility when selecting a site.
C. Instruct the patient to hold his arm in a dependent position before insertion.
D. Remove the tourniquet after 2 minutes.

Correct answer: B

Rationale: When selecting a site for IV insertion on the hand or arm, it is important to consider the potential effects on the patient's mobility. The chosen site should not interfere with the patient's movement. Instructing the patient to hold his arm in a dependent position helps increase blood flow, aiding in vein visualization and insertion. It is advisable to choose a site with minimal hair if possible for better adhesion of the dressing. Removing the tourniquet after 2 minutes is recommended to prevent complications like hemoconcentration and potential vein damage. Therefore, option B is the correct choice as it aligns with best practices for IV insertion.

4. A medical-surgical nurse is concerned about the incidence of complications related to IV therapy, including bloodstream infection. Which intervention should the nurse suggest to the management team to make the biggest impact on decreasing complications

A. Initiate a dedicated team to insert access devices
B. . Require additional education for all nurses.
C. Limit the use of peripheral venous access devices.
D. Perform quality control testing on skin preparation products.

Correct answer: A

Rationale:

5. The chief mechanism for maintaining fluid balance is to:

A. adjust fluid intake so it equals fluid output.
B. adjust fluid intake so it is slightly above fluid output.
C. adjust fluid output so it equals fluid input.
D. adjust fluid intake so it is slightly below fluid output.

Correct answer: C

Rationale: The correct answer is C: 'adjust fluid output so it equals fluid input.' Maintaining fluid balance involves ensuring that the amount of fluid lost through processes like urination, sweating, and respiration equals the amount of fluid taken in. This ensures that the body stays properly hydrated. Choices A, B, and D are incorrect because they do not focus on the balance between fluid input and output, which is crucial for maintaining proper fluid balance. By adjusting fluid output to equal fluid input, the body can regulate hydration levels effectively, preventing dehydration or overhydration.
