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 B
Explanation
Choice A rationale:
An elevated WBC count (11,000/mm²) in a client starting treatment for MRSA infection may indicate an inflammatory response, but it is expected in this scenario, and the priority is not as high as other critical lab values.
Choice B rationale:
A serum pH of 7.25 indicates acidosis, which is a potentially life-threatening condition. In type 1 diabetes mellitus, diabetic ketoacidosis (DKA) is a common complication that can lead to metabolic acidosis. This lab result is a priority as it requires immediate attention.
Choice C rationale:
Hematocrit of 26% in a client with sickle cell disease might be low, but it is not the priority over the critically abnormal lab value of serum pH in option B.
Choice D rationale:
A urine specific gravity of 1.032 in a client diagnosed with dehydration is elevated, indicating concentrated urine due to dehydration. While dehydration is concerning, it is not as high-priority as the potentially life-threatening acidosis in option B.
Correct Answer is B
Explanation
Choice A rationale:
Scheduling the client for the last surgery of the day is not directly related to the client's latex allergy. Proper planning for surgery in a latex-allergic client involves addressing potential exposures to latex-containing products and minimizing the risk of allergic reactions.
Choice B rationale:
Placing monitoring cords and tubes in a stockinette can help create a barrier between the client's skin and the latex-containing products. This measure helps reduce the risk of direct contact with latex, which could trigger an allergic reaction in a latex-sensitive individual.
Choice C rationale:
Choosing rubber injection ports for fluid administration is not appropriate for a client with a latex allergy. Rubber products often contain latex, which can lead to an allergic reaction in susceptible individuals.
Choice D rationale:
Having phenytoin IV readily available is not directly relevant to a client with a latex allergy. Phenytoin is an antiepileptic medication and should be available for clients who require it, but it does not address the specific concern of latex exposure.
