A client is receiving intravenous (IV) potassium replacement therapy.
Which of the following actions should the nurse take to prevent complications?
Monitoring urine output every 8 hours.
Administering potassium via a bolus injection.
Administering potassium at a rate no faster than 10-20 mEq/hour.
Encouraging the client to eat potassium-rich foods.
The Correct Answer is C
This is because intravenous potassium supplementation is indicated for patients with profound hypokalemia (plasma K+ <2.5 mmol/L) or cardiac arrhythmia. The rate of infusion should not exceed 10 mmol/hour to prevent complications such as hyperkalemia, cardiac arrhythmias, and phlebitis.
Choice A is wrong because monitoring urine output every 8 hours is not sufficient to prevent complications from intravenous potassium replacement therapy.
Urine output should be monitored more frequently (at least every 4 hours) to assess renal function and fluid balance.
Choice B is wrong because administering potassium via a bolus injection is dangerous and can cause fatal cardiac arrhythmias.
Potassium should never be given by intravenous push or intramuscular injection.
Choice D is wrong because encouraging the client to eat potassium-rich foods is not appropriate for patients receiving intravenous potassium replacement therapy.
Oral potassium supplementation is preferred for patients with mild to moderate hypokalemia (plasma K+ 2.5-3.5 mmol/L) who can eat and absorb oral potassium.
Potassium-rich foods include potatoes, legumes, juices, seafood, leafy greens, dairy, tomatoes and bananas.

Correct Answer is ["23"]
Explanation
The correct answer is 22.5 mL.
To find the amount of mL, use the formula: (desired dose / available dose) x available volume.
In this case, desired dose = 30 mEq, available dose = 20 mEq, and available volume = 15 mL.
Plug these values into the formula: (30 mEq / 20 mEq) x 15 mL = 22.5 mL.
However, since the instructions say to round to the nearest whole number for adult clients, the final answer is 23 mL.
Correct Answer is D
Explanation
Monitoring the client’s electrolyte levels before and after the treatment. This is because acute kidney injury (AKI) can cause electrolyte imbalances such as hyperkalemia, hyperphosphatemia, hypocalcemia, and metabolic acidosis. Hemodialysis can help correct these imbalances by removing excess fluid and waste products from the blood. However, hemodialysis can also cause electrolyte shifts and complications such as hypotension, muscle cramps, and arrhythmias. Therefore, it is important to monitor the client’s electrolyte levels before and after the treatment to assess the effectiveness and safety of hemodialysis.
Choice A is wrong because monitoring the client’s blood pressure every 4 hours is not frequent enough during hemodialysis.
Hemodialysis can cause rapid changes in blood pressure due to fluid removal and vascular access.
Therefore, blood pressure should be monitored more often, such as every 15 to 30 minutes during hemodialysis.
Choice B is wrong because administering a loop diuretic before the treatment is not indicated for AKI patients receiving hemodialysis.
Loop diuretics are used to increase urine output and reduce fluid overload in AKI patients who have some residual kidney function.
However, hemodialysis can achieve the same goal by removing excess fluid from the blood.
Moreover, loop diuretics can cause electrolyte depletion and ototoxicity, which can worsen the condition of AKI patients.
Choice C is wrong because assessing the client’s respiratory status every 2 hours is not specific enough for hemodialysis treatment.
Hemodialysis can affect respiratory mechanics by altering fluid balance, acid- base status, and oxygen delivery.
Therefore, respiratory status should be assessed more frequently and comprehensively during hemodialysis, such as by measuring respiratory rate, oxygen saturation, arterial blood gas, and chest auscultation.
