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

Excess body weight, particularly in the abdominal area, can increase intra-abdominal pressure and lead to the weakening of the lower esophageal sphincter (LES). The LES is responsible for preventing stomach acid from flowing back into the esophagus. When it becomes weakened, it can contribute to the development of GERD. Other risk factors for GERD include certain dietary choices, such as consuming fatty and spicy foods, smoking, pregnancy, and alcohol consumption.

A. Pain responding well to prescribed dose of Morphine. B. ltching unrelieved by Diphenhydramine (Benadryl administration. C. Lower extremities temperature cool bilaterally. D. Tingling in the toes of fractured extremity and decreased sensation.

Correct Answer is D

Explanation

Compartment syndrome is a condition characterized by increased pressure within a muscle compartment, leading to impaired blood flow and potential tissue damage. It can occur when swelling or bleeding within a confined space, such as a cast, causes increased pressure on the surrounding tissues.

Tingling in the toes and decreased sensation can be indicative of nerve compression or damage due to increased pressure in the compartment. It is important to recognize these neurological changes as potential signs of compartment syndrome.

Signs and symptoms of compartment syndrome may include:

Severe pain that is out of proportion to the injury or not relieved by pain medication.
Swelling and tightness in the affected area.
Numbness or tingling.
Pale or cool skin over the affected area.
Weakness or decreased sensation in the affected limb.
In severe cases, paralysis or loss of pulse in the affected area.
