A patient has a folic acid deficiency associated with not consuming food with folic acid. The nurse would expect a complete blood cell count (CBC) to reveal?

Choice A reason: Patient should increase daily iron supplements, is a statement that indicates a need for additional teaching. Iron supplements are not recommended for patients with beta-thalassemia, because they already have high levels of iron in their blood due to the frequent blood transfusions. Excess iron can cause damage to the liver, heart, and other organs. Therefore, the patient should avoid iron supplements and foods rich in iron, and take chelation therapy to remove the excess iron from the body.

Choice B reason: Signs and symptoms of infection, is a statement that does not indicate a need for additional teaching. Patients with beta-thalassemia are at risk of developing infections, due to the impaired immune system and the exposure to blood-borne pathogens. Therefore, the patient should be aware of the signs and symptoms of infection, such as fever, chills, sore throat, cough, or skin lesions, and seek medical attention promptly.

Choice C reason: Our child will need to have blood transfusions, is a statement that does not indicate a need for additional teaching. Blood transfusions are the main treatment for patients with beta-thalassemia, because they help to increase the level of hemoglobin and red blood cells, and prevent anemia and its complications. Therefore, the patient should receive regular blood transfusions, usually every two to four weeks, depending on the severity of the condition.

Choice D reason: Swimming is a good activity for our child, is a statement that does not indicate a need for additional teaching. Swimming is a good activity for patients with beta-thalassemia, because it helps to improve the cardiovascular fitness, muscle strength, and joint mobility, and reduce the stress and fatigue. Therefore, the patient should engage in moderate physical activities, such as swimming, walking, or cycling, as tolerated, and avoid strenuous or competitive sports that can cause injury or dehydration.

Choice A reason: Completing a halo test with the fluid is the initial intervention that the nurse should perform, as it can help to determine if the fluid is cerebrospinal fluid (CSF) or not. CSF is the fluid that surrounds and protects the brain and spinal cord, and it can leak from the nose or ears after a head injury. A halo test involves placing a drop of the fluid on a piece of filter paper or gauze and observing the color and shape of the stain. If the fluid is CSF, it will form a yellowish ring around a central blood spot, creating a halo effect.

Choice B reason: Taping a sterile gauze pad under the nose and monitoring the amount of fluid is not the initial intervention that the nurse should perform, as it does not help to identify the type of fluid. It may also increase the risk of infection or pressure on the brain if the fluid is CSF.

Choice C reason: Documenting the presence of rhinorrhea is not the initial intervention that the nurse should perform, as it does not help to diagnose or treat the condition. Rhinorrhea is the medical term for a runny nose, which can have many causes, such as allergies, colds, or sinus infections. It is not a specific sign of a head injury or CSF leakage.

Choice D reason: Informing the physician of the assessment is an important intervention that the nurse should perform, but not the initial one. The nurse should first confirm if the fluid is CSF or not, as this can affect the management and prognosis of the patient. The nurse should then report the findings and the patient's vital signs, neurological status, and other relevant information to the physician.
