A nurse is preparing to administer potassium chloride 30 mEq PO daily. The amount available is potassium chloride 20 mEq/15mL. How many mL should the nurse administer?

(Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["23"]

To determine how many milliliters (mL) of potassium chloride the nurse should administer to provide 30 mEq, we can set up a proportion:

20 mEq is contained in 15 mL. So, to find out how many mL contain 30 mEq, we can set up the proportion:

20 mEq:15 mL=30 mEq:? mL20mEq:15mL=30mEq:xmL

Cross multiply:

20×?=15×3020×x=15×30

20?=45020x=450

Now, solve for ?x:

?=45020x=20450

?=22.5x=22.5

So, the nurse should administer approximately 22.5 mL of potassium chloride.

Rounded to the nearest whole number, this would be 23 mL.

Therefore, the nurse should administer 23 mL of potassium chloride.

Correct Answer is C

Explanation

  1. White Blood Cell Count (WBC): WBCs are part of the immune system and play a role in fighting infections. However, they are not directly involved in hemostasis or clot formation. WBCs do not adhere to the vessel wall during hemostasis.
  2. Activated Partial Thromboplastin Time (aPTT): aPTT measures the time it takes for blood to clot. It is primarily used to monitor heparin therapy, not warfarin. aPTT is not specific for warfarin monitoring.
  3. Prothrombin Time (PT): PT measures how quickly blood clots. It is used to monitor warfarin therapy and assess clotting factors. PT is essential for monitoring warfarin effectiveness.
  4. Platelet Count: Platelets are crucial for clot formation. Platelet count helps assess platelet function. Platelets play a direct role in hemostasis.

Correct Answer is {"dropdown-group-1":"A"}

Explanation

A. Whole: Complementary and alternative medicine (CAM) emphasizes treating the entire person, considering physical, mental, emotional, and spiritual aspects of health. It aims to restore balance and promote overall well-being.

B. Diseased: CAM focuses on addressing the root cause of illness, not just treating the symptoms of a disease. While disease management can be a part of CAM, it's not the sole focus.

C. Partial: CAM doesn't focus on treating only a part of the person. It aims for a comprehensive approach.

D. Impaired: While CAM can be used to address impairments, it has a broader scope that encompasses promoting overall health and preventing illness, not just treating existing limitations
