A patient with hypophosphatemia has serious symptoms and cannot use the oral route. Which plan best fits the guidance for replacement?

A
The patient has severe deficiency or serious symptoms, and phosphate, calcium, potassium, and renal function can be closely monitored.
B
The patient has a mild deficiency and can take oral medication.
C
The patient has hyperphosphatemia and needs a phosphate binder.
D
The patient's kidney function is unknown, so monitoring can be deferred until after replacement.

A patient has hypernatremia of unknown duration. Explain why correction should be gradual and describe how water replacement may be provided.

1 point

A patient with impaired renal function needs electrolyte replacement. Which principle should guide the plan?

A
Use the usual replacement plan because renal impairment does not affect electrolyte accumulation.
B
Adjust replacement and monitoring because impaired renal function increases the risk of accumulation.
C
Avoid reassessing laboratory values after replacement.
D
Use IV replacement in every case, regardless of severity or symptoms.

A patient has hypernatremia of unknown duration. Which management principles are appropriate? Select all that apply.

A
Replace water orally or enterally when safe.
B
Correct chronic or unknown-duration hypernatremia rapidly to normalize sodium as soon as possible.
C
Choose IV fluid according to the patient's volume status when IV replacement is needed.
D
Lower sodium gradually when the duration is chronic or unknown.

1 point

A stable patient with an electrolyte deficiency can take and absorb medication by mouth. Which replacement approach is generally preferred?

A
Use IV replacement routinely because it acts faster.
B
Choose oral replacement when the patient is stable and can take and absorb it.
C
Delay replacement until symptoms develop.
D
Use the same route regardless of the patient's condition.

1 point

A patient with hyperphosphatemia related to reduced kidney excretion is prescribed phosphate binders. When should the patient take the binders?

A
Take phosphate binders only between meals.
B
Increase dietary phosphate to support bone health.
C
Take prescribed phosphate binders with meals.
D
Replace phosphate routinely by IV.

A patient with hypercalcemia also has heart failure. Which approach to hydration is most appropriate?

A
Give isotonic saline without regard to cardiac or renal status.
B
Consider isotonic saline, individualizing hydration for heart or kidney failure.
C
Restrict all fluids because calcium is elevated.
D
Treat with IV calcium to lower the serum calcium.

True or false

1 point

A patient with hyperkalemia receives IV calcium. This treatment protects the heart when indicated, but it does not itself lower the serum potassium.

A
True
B
False

Choose one

1 point

A patient's total calcium result does not seem consistent with the clinical findings. How should the nurse interpret the result?

A
Interpret total calcium in the context of albumin and consider ionized calcium if results or symptoms are unclear.
B
Assume total calcium always reflects the biologically active calcium.
C
Use potassium results to determine whether total calcium is accurate.
D
Ignore calcium trends if the patient has no muscle symptoms.

Written response

1 point

During active correction of hyponatremia, a patient is being monitored over the first 24 hours. What is the commonly used maximum sodium increase during that period? Enter the value in mmol/L.
