ATI Fluid Electrolyte and Acid-Base Regulation
1. A nurse in the neurologic ICU has orders to infuse a hypertonic solution into a patient with increased intracranial pressure. This solution will increase the number of dissolved particles in the patients blood, creating pressure for fluids in the tissues to shift into the capillaries and increase the blood volume. This process is best described as which of the following?
- A. Hydrostatic pressure
- B. Osmosis and osmolality
- C. Diffusion
- D. Active transport
Correct answer: B
Rationale:
2. 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.
3. A nurse is caring for a client who is receiving an epidural infusion for pain management. Which assessment finding requires immediate intervention from the nurse?
- A. Redness at the catheter insertion site
- B. Report of headache and stiff neck
- C. Temperature of 100.1 F (37.8 C)
- D. Pain rating of 8 on a scale of 0 to 10
Correct answer: B
Rationale:
4. . A nurse assesses a client with diabetes mellitus who is admitted with an acid-base imbalance. The clients arterial blood gas values are pH 7.36, PaO2 98 mm Hg, PaCO2 33 mm Hg, and HCO3 18 mEq/L. Which manifestation should the nurse identify as an exam
- A. Increased rate and depth of respirations
- B. ncreased urinary output
- C. Increased thirst and hunger
- D. ncreased release of acids from the kidneys
Correct answer: A
Rationale:
5. How would a decrease in blood protein concentration impact the fluid volumes?
- A. increase interstitial fluid volume.
- B. decrease blood plasma volume.
- C. decrease interstitial fluid volume.
- D. increase interstitial fluid volume and decrease blood plasma volume.
Correct answer: D
Rationale: A decrease in blood protein concentration would lead to a reduction in osmotic pressure, which is responsible for drawing fluid back into the capillaries. This decrease in osmotic pressure would result in an increase in interstitial fluid volume as fluid moves out of the capillaries, and a decrease in blood plasma volume as less fluid is drawn back into the circulation. Therefore, the correct answer is to increase interstitial fluid volume and decrease blood plasma volume. Choices A, B, and C are incorrect because they do not reflect the impact of decreased blood protein concentration on fluid volumes.
