The nurse is preparing to administer a shot of vitamin B12 to a client with low hemoglobin. The nurse knows that this medication is most indicative of which type of anemia?

Pernicious anemia

Hemolytic anemia

Iron deficiency anemia

Aplastic anemia

Answer and Explanation

The Correct Answer is A

A) Pernicious anemia:
Vitamin B12 injections are most commonly used to treat pernicious anemia, which is caused by a deficiency in vitamin B12 due to an inability to absorb the vitamin from the gastrointestinal tract. This condition is often associated with a lack of intrinsic factor, a protein required for vitamin B12 absorption. As a result, the body cannot make enough healthy red blood cells, leading to anemia. The treatment of pernicious anemia typically involves lifelong vitamin B12 injections, making this the correct answer.

B) Hemolytic anemia:
It is not typically treated with vitamin B12 injections. Instead, hemolytic anemia may require treatments that address the underlying cause of red blood cell destruction, such as corticosteroids, immunosuppressive therapy, or splenectomy, depending on the type of hemolysis. Therefore, vitamin B12 would not be the primary treatment for this type of anemia.

C) Iron deficiency anemia:
It is typically treated with iron supplements, either orally or intravenously, rather than vitamin B12. While both conditions cause anemia, the treatment for iron deficiency anemia is not vitamin B12, so this is not the correct choice.

D) Aplastic anemia:
This condition is usually treated with treatments such as bone marrow stimulants, blood transfusions, or bone marrow transplantation, rather than vitamin B12. Vitamin B12 supplementation would not be indicated for the treatment of aplastic anemia.

Correct Answer is C

Explanation

A) Having 2 RNs ensure the blood product is properly labeled and matches the client’s identification:
Two registered nurses must independently verify that the blood product matches the patient's identification and that it is properly labeled. This is a critical safety measure to prevent errors, such as mismatched blood transfusions, which can lead to severe complications like hemolytic reactions. Proper verification before administration is a standard safety protocol in blood transfusion procedures.

B) Ensuring that the client signed a consent form for receiving blood transfusions beforehand:
Obtaining informed consent is a vital legal and ethical step before administering a blood transfusion. The nurse must ensure that the patient understands the potential risks and benefits of the procedure and has signed a consent form prior to transfusion. Without consent, the transfusion cannot legally be performed. This is a key part of patient rights and nursing responsibilities.

C) Preparing a primary and secondary IV tubing:
For blood transfusions, only blood administration tubing should be used, which typically includes a filter to prevent the infusion of any debris or clots. Using regular IV tubing (primary and secondary) for blood administration is not recommended, as it may not have the necessary filter and could potentially introduce contaminants. Blood should always be administered with tubing specifically designed for that purpose.

D) Obtaining a bag of 0.9% sodium chloride:
Normal saline is typically used as the solution to flush the IV line before and after the transfusion. It is compatible with blood products and helps to prevent clotting or reactions in the line. This is an essential step to ensure safe and effective blood administration.

Correct Answer is ["7"]

Explanation

Given:

Desired dose: Amoxicillin 350 mg PO

Available concentration: Amoxicillin 250 mg/5 ml

To find:

Volume to administer (in ml)

Step 1: Set up the proportion

We can use the following proportion to solve the problem:

(Desired dose) / (Available concentration) = Volume to administer

Step 2: Substitute the values

Plugging in the given values, we get:

(350 mg) / (250 mg/5 ml) = Volume to administer

Step 3: Simplify

To simplify, we can invert the denominator and multiply:

(350 mg) x (5 ml / 250 mg) = Volume to administer

The "mg" units cancel out, leaving us with:

(350 x 5 ml) / 250 = Volume to administer

Step 4: Calculate

Performing the multiplication and division, we get:

1750 ml / 250 = Volume to administer

1 ml = Volume to administer
