A nurse is monitoring a client who is receiving a unit of packed red blood cells (RBCs) following surgery. Which of the following assessments is an indication that the client might be experiencing circulatory overload?

Choice A reason: Reducing intake of potassium-rich foods is not necessary for clients taking hydrochlorothiazide, as this medication can cause hypokalemia (low potassium levels) due to increased potassium excretion in the urine. Clients may need to increase their intake of potassium-rich foods or take potassium supplements to prevent hypokalemia.

Choice B reason: Avoiding grapefruit juice is not necessary for clients taking hydrochlorothiazide, as this medication does not interact with grapefruit juice. Grapefruit juice can affect the metabolism of some other medications, such as statins, calcium channel blockers, and cyclosporine, by inhibiting the enzyme CYP3A4 in the liver.

Choice C reason: Taking this medication before bedtime is not advisable for clients taking hydrochlorothiazide, as this medication can cause increased urination and nocturia (nighttime urination). Clients should take this medication in the morning or at least 6 hours before bedtime to avoid disrupting their sleep.

Choice D reason: Monitoring for leg cramps is an important instruction for clients taking hydrochlorothiazide, as this medication can cause muscle cramps due to electrolyte imbalances, such as hypokalemia, hyponatremia (low sodium levels), or hypomagnesemia (low magnesium levels). Clients should report any signs of muscle cramps, weakness, or fatigue to their provider.

Choice A - Catheter Occlusion: This occurs when the catheter is blocked, preventing the flow of fluids or medication. It is usually indicated by difficulty in flushing the catheter or a slow drip rate¹. However, it does not typically cause a gurgling sound.

Choice B - (Catheter migration) is correct because when a central venous catheter (CVC) migrates from its original position, the tip can enter a smaller vein or a different location where turbulence occurs. This may cause the client to hear a gurgling or bubbling sound, especially during infusion or with position changes. Migration can happen due to coughing, movement, or changes in pressure, and it doesn’t necessarily involve the catheter being visibly out of place

Choice C - (Catheter dislodgment) is incorrect because dislodgment typically refers to the catheter being partially pulled out of the insertion site. This would be more likely to cause external signs like visible catheter movement or fluid leakage at the insertion site, rather than internal gurgling sounds. Gurgling is more associated with internal changes in catheter position, as seen with migration.

Choice D - Catheter Rupture: This is a break or tear in the catheter. It can cause serious complications, including infection and embolism. However, a gurgling sound is not a typical symptom of a catheter rupture¹.
