ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse is caring for a client who has just had a central venous access line inserted. Which action should the nurse take next?

Correct answer: B

Rationale:

2. A patient admitted with a gastrointestinal bleed and anemia is receiving a blood transfusion. Based on the patient's hypotensive blood pressure, the nurse anticipates an order for IV fluids from the physician. Which of the following IV solutions may be administered with blood products?

Correct answer: D

Rationale: The correct answer is D: 0.9% NaCl. The only IV solution that can be administered with blood products is normal saline (0.9% NaCl). This solution is compatible with most blood products and is commonly used during transfusions to maintain hemodynamic stability. Choices A, B, and C are incorrect. Choice A, D5 and 0.45% Normal Saline, contains dextrose and is not recommended to be given simultaneously with blood products. Choice B, Lactated Ringer's, contains calcium, which can cause coagulation and should not be mixed with blood. Choice C, 5% dextrose in water, is hypotonic and not suitable to be administered with blood products.

3. A nurse in the medical-surgical unit is giving a patient with low blood pressure a hypertonic solution, which will increase the number of dissolved particles in his blood, creating pressure for fluids in the tissues to shift into the capillaries and increase the blood volume. Which of the following terms is associated with this process?

Correct answer: B

Rationale: Osmosis is the movement of fluid from a region of low solute concentration to a region of high solute concentration across a semipermeable membrane. The number of dissolved particles contained in a unit of fluid determines the osmolality of a solution, which influences the movement of fluid between the fluid compartments. Giving a patient who has low blood pressure a hypertonic solution will increase the number of dissolved particles in the blood, creating pressure for fluids in the tissues to shift into the capillaries and increase the blood volume. Option A is incorrect; hydrostatic pressure refers to changes in water or volume related to water pressure. Option C is incorrect; diffusion is the movement of solutes from an area of greater concentration to lesser concentration. The solutes in an intact vascular system are unable to move, so diffusion should not normally take place. Option D is incorrect; active transport is the movement of molecules against the concentration gradient and requires ATP as an energy source. This process typically takes place at the cellular level and is not involved in vascular volume changes.

4. . A nurse is planning care for a nephrology patient with a new nursing graduate. The nurse states, A patient in renal failure partially loses the ability to regulate changes in pH. What is the cause of this partial inability?

Correct answer: C

Rationale:

5. You are caring for a patient who is being treated on the oncology unit with a diagnosis of lung cancer with bone metastases. During your assessment, you note the patient complains of a new onset of weakness with abdominal pain. Further assessment suggests that the patient likely has a fluid volume deficit. You should recognize that this patient may be experiencing what electrolyte imbalance?

Correct answer: D

Rationale:
