A nurse is preparing to administer potassium chloride 10 mEq IV over 1 hr to a client. Available in potassium chloride 10 mEq in 100 mL of 0.9% sodium chloride. The nurse should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.).
10 mL/hr.
50 mL/hr.
100 mL/hr.
500 mL/hr.
The Correct Answer is C
Choice A rationale:
10 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 1 hour. However, the question asks for the rate at which to administer 10 mEq over 1 hour, which means the total volume should be 100 mL/hr.
Choice B rationale:
50 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 2 hours. However, the question specifies 1 hour, so the rate should be higher.
Choice C rationale:
This is the correct answer. To administer 10 mEq of potassium chloride in 100 mL over 1 hour, the infusion pump should be set to deliver 100 mL/hr.
Choice D rationale:
500 mL/hr would be the correct infusion rate if the client was receiving the entire 10 mEq of potassium chloride in a 100 mL solution over 10 minutes (1/6th of an hour). However, the question specifies 1 hour, so the rate should be much lower.

Correct Answer is ["A","C","D","E"]
Explanation
Choice A rationale:
Is appropriate to assess postoperative urinary function after transurethral resection of the prostate (TURP). It helps monitor the return of normal bladder function.
Choice B rationale:
Is not necessary and could potentially cause discomfort and increased risk of tube dislodgment. Securing the tube properly to the bed or clothing is a more appropriate method.
Choice C rationale:
Is essential to assess urinary function, and fluid balance, and identify any potential complications such as urinary retention or excessive bleeding.
Choice D rationale:
Helps alleviate discomfort and prevent spasms after TURP. Bladder spasms can be common after the procedure, and antispasmodics can aid in managing them.
Choice E rationale:
Is necessary to keep the catheter patent and prevent clot formation in the urinary tract. It helps maintain proper drainage and prevents complications.
Correct Answer is A
Explanation
Choice A rationale:
Wearing gloves when changing the cat's litter box is essential during chemotherapy because some chemotherapy drugs can be excreted in bodily fluids, including feces. Protecting against direct contact with potentially harmful substances is crucial to minimize exposure risks.
Choice B rationale:
Taking the temperature once each week is not a relevant precaution during chemotherapy. Monitoring temperature is important, but it should be done more frequently, such as daily, as chemotherapy can cause immunosuppression, increasing the risk of infection.
Choice C rationale:
Being able to attend a concert is not related to precautions during chemotherapy. It is essential for clients undergoing chemotherapy to avoid large gatherings and events where they might be exposed to infections.
Choice D rationale:
Allowing the toothbrush to dry completely between each use is a good hygiene practice but not specifically related to chemotherapy precautions. Proper oral hygiene is essential during chemotherapy, but using a soft toothbrush and regularly replacing it are more relevant considerations.
