The nurse will plan to teach a patient who has pernicious anemia about the need for:

Oral ferrous sulfate tablets.

Cobalamin (B) Injections.

Iron dextran infusions

Routine blood transfusions.

Answer and Explanation

The Correct Answer is B

Pernicious anemia is a type of anemia that occurs due to a lack of intrinsic factor, a protein necessary for the absorption of vitamin B12 (cobalamin) in the digestive system. As a result, patients with pernicious anemia are unable to absorb sufficient amounts of vitamin B12 from dietary sources. The treatment for pernicious anemia involves regular administration of cobalamin (B12) injections to bypass the impaired absorption and provide the necessary vitamin B12 directly.

Oral ferrous sulfate tablets are not the appropriate treatment for pernicious anemia. Ferrous sulfate is a form of iron supplement used to treat iron deficiency anemia, which is different from pernicious anemia.

Iron dextran infusions are also not indicated for pernicious anemia. Iron dextran is used for iron replacement therapy in cases of iron deficiency anemia, but it does not address the underlying issue of vitamin B12 deficiency in pernicious anemia.

Routine blood transfusions may be necessary in some cases of pernicious anemia, especially if the patient is severely anemic. However, the primary treatment for pernicious anemia is cobalamin (B12) injections, which provide the necessary vitamin B12 that the patient is unable to absorb.

Correct Answer is B

Explanation

In a child with acute appendicitis, it is common to observe an elevated white blood cell count (WBC) as a response to the infection or inflammation associated with the condition. The neutrophil count may be within the lower end of the normal range or slightly decreased, as it can be affected by the severity and duration of the appendicitis. The red blood cell count (RBC) appears to be within the normal range. The lactic acid level is normal, indicating no significant metabolic acidosis.

Correct Answer is ["1.4"]

Explanation

We know that 7,000 units is equivalent to 5,000 units per ml. So, we can set up the proportion:

7,000 units / 5,000 units per ml = x ml / 1 ml x = 7,000 / 5,000

x = 1.4

Therefore, the nurse should administer 1.4 milliliters (ml) of heparin.
