Chapter 16 : Caring for Clients With Fluid, Electrolyte, and Acid? Base Imbalances Questions
Question 1 of 5
Which laboratory result does the nurse identify as a direct result of the client's hypovolemic status with hemoconcentration?
Correct Answer: B
Rationale: When hemoconcentration occurs due to a hypovolemic state, a high ratio of blood components in relation to watery plasma occurs, thus causing an elevated hematocrit level. A high white blood cell count and urine specific gravity is also noted. Other causes of an abnormal potassium level may be present.
Question 2 of 5
The nurse is caring for a client in heart failure with signs of hypervolemia. Which vital sign is indicative of the disease process?
Correct Answer: B
Rationale: Indicative of hypervolemia is a bounding pulse and elevated blood pressure due to the excess volume in the system. Respirations are not typically affected unless there is fluid accumulation in the lungs. Temperature is not generally affected.
Question 3 of 5
A nurse is providing an afternoon shift report and relates morning assessment findings to the oncoming nurse. Which daily assessment data is necessary to determine changes in the client's hypervolemia status?
Correct Answer: D
Rationale: Daily weight provides the ability to monitor fluid status. A 2-lb $(0.9 \mathrm{kg})$ weight gain in 24 hours indicates that the client is retaining $1 \mathrm{~L}$ of fluid. Also, the loss of weight can indicate a decrease in edema. Vital signs do not always reflect fluid status. Edema could represent a shift of fluid within body spaces and not a change in weight. Intake and output do not account for unexplainable fluid loss.
Question 4 of 5
The nurse is documenting assessment findings of a client diagnosed with anasarca. Which nursing documentation best shows improvement in disease progression?
Correct Answer: A
Rationale: Third-spacing is the translocation of fluid from the intravascular to intercellular space to tissue compartment. Anasarca is the general edema in the organ cavities such as the abdomen. Monitoring the abdominal girth provides data on the localization of the fluid in the interstitial space. A decrease in girth, in particular, notes improvement. Level of consciousness is not affected unless shock occurs. Weight remains the same as there is a shifting in fluid; pulse rate could fluctuate according to fluid movement.
Question 5 of 5
Which nursing action is anticipated by the nurse to restore colloidal osmotic pressure to clients with third-spacing?
Correct Answer: B
Rationale: The best answer to restore colloidal osmotic pressure is to initiate an IV of albumin. Administration of albumin pulls the trapped fluid back into the intravascular space. An isotonic solution will not pull water from the intercellular space. Blood products are used for third-spacing management; however, albumin is the product of choice. The management of total parenteral nutrition is not associated with third- spacing.
