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 C
Explanation
Choice A rationale:
Using fingers to remove loose tissue is not an appropriate action for the nurse to take when providing hydrotherapy for a burn wound. This action can cause further trauma to the wound and increase the risk of infection.
Choice B rationale:
Opening small blisters to expose air is contraindicated in burn wound management. The blister roof provides a natural barrier against infection, and puncturing them increases the risk of infection and delays the healing process.
Choice C rationale:
The correct answer is to wash the burn with a mild soap. Cleaning the burn wound with mild soap and water helps remove debris and minimize the risk of infection without causing additional damage.
Choice D rationale:
Applying wet-to-dry dressings is an outdated and inappropriate practice for burn wound care. Wet-to-dry dressings can be painful, disrupt wound healing, and increase the risk of infection. Modern burn wound care focuses on maintaining a moist environment to support optimal healing.
Correct Answer is A
Explanation
Choice A rationale:
Testicular cancer may present as a painless lump or swelling in the testicle. It's important for the client to monitor for any new or unusual lumps, as they could be indicative of cancer.
Choice B rationale:
A decreased size of the testicle is not a typical manifestation of testicular cancer. It is more commonly associated with conditions like testicular atrophy due to other causes.
Choice C rationale:
Asymmetry in the position of the testicles, with one testicle descending lower than the other, is a normal variation and not a sign of testicular cancer.
Choice D rationale:
Dilated veins above the testicle can be a sign of a varicocele, which is a separate condition from testicular cancer. It is caused by abnormal enlargement of veins in the scrotum and is generally not associated with cancer.
