Chapter 16 : Caring for Clients With Fluid, Electrolyte, and Acid? Base Imbalances Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The nurse is caring for four clients on a medical unit. Which client's laboratory reports does the nurse review first for an electrolyte imbalance?
Correct Answer: C
Rationale: Electrolytes are in both intracellular and extracellular water. Electrolyte deficiency occurs from an inadequate intake of food, conditions that deplete water such as nausea and vomiting, or disease processes that cause an excess of electrolyte amounts. The 52-year-old with diarrhea would be the client most likely to have an electrolyte imbalance. The orthopedic client will not likely have an electrolyte imbalance. Myocardial infarction clients will occasionally have electrolyte imbalance, but this is the exception rather than the rule.
Question 5 of 5
The nurse is reviewing client lab work for a critical lab value. Which value is called to the health care provider for additional prescriptions?
Correct Answer: A
Rationale: Normal potassium level is 3.5 to $5.5 \mathrm{mEq} / \mathrm{L}$. Elevated potassium levels can lead to muscle weakness, paresthesias, and cardiac dysrhythmias.
