A nurse is caring for four children in an emergency department. Which of the following clients should the nurse assess first?

A. Obtain urinary samples by disconnecting the tubing connections:
This action increases the risk of contamination and introduces bacteria into the urinary system, potentially leading to UTIs. Urine samples should be obtained using a sterile technique to minimize the risk of infection.

B. Secure the catheter to the client's thigh:
Securing the catheter to the client's thigh can cause tension and traction on the catheter, increasing the risk of urethral trauma and introducing bacteria into the urinary tract. Catheters should be secured without tension to prevent damage to the urethra and reduce the risk of UTIs.

C. Keep the urinary bag at bladder level when ambulating:
Keeping the urinary bag at bladder level when ambulating prevents urine from flowing back into the bladder, reducing the risk of UTIs. Gravity drainage helps maintain the flow of urine and prevents stasis, which can contribute to bacterial growth and UTIs.

D. Loop the tubing so that it is lower than the collection bag:
Looping the tubing so that it is lower than the collection bag creates a dependent loop where urine can accumulate, increasing the risk of bacterial colonization and UTIs. The tubing should be kept straight and free of kinks to ensure continuous drainage and prevent urine from pooling in the tubing.

A. Iron: Iron supplements are not typically contraindicated with spironolactone use. Spironolactone is a potassium-sparing diuretic and may lead to hyperkalemia, but iron supplements are not directly associated with this risk.
B. Calcium: Calcium supplements are not typically contraindicated with spironolactone use. However, calcium supplements should be taken separately from spironolactone to avoid potential interactions that may reduce the absorption of both medications.
C. Magnesium: Magnesium supplements are not typically contraindicated with spironolactone use. However, magnesium-containing antacids should be used with caution due to the potential for increased magnesium levels in the body, especially in individuals with impaired renal function.
D. Potassium: Spironolactone is a potassium-sparing diuretic, meaning it helps retain potassium in the body. Concurrent use of potassium supplements or foods high in potassium can lead to hyperkalemia when combined with spironolactone. Therefore, the client should avoid potassium supplements while taking spironolactone to prevent this risk.
