The nurse should instruct a young female adult with sickle cell anemia to do which of the following?
Avoid travel to cities where the oxygen level is lower
Strenuous exercise prevents the development of sickle cell crisis
Avoid flying on commercial airlines
Drink plenty of fluids when outside in hot weather
The Correct Answer is D
Choice A reason: This is incorrect. Traveling to cities where the oxygen level is lower, such as high-altitude areas, can trigger a sickle cell crisis by reducing the amount of oxygen in the blood. People with sickle cell anemia should avoid such places or take precautions such as using supplemental oxygen¹².
Choice B reason: This is incorrect. Strenuous exercise does not prevent sickle cell crisis, but rather can cause it by increasing the body's oxygen demand and dehydration. People with sickle cell anemia should avoid overexertion and rest frequently during physical activity¹³.
Choice C reason: This is incorrect. Flying on commercial airlines is not prohibited for people with sickle cell anemia, as long as they stay hydrated and avoid alcohol and caffeine. However, some people may need to use supplemental oxygen during flights, especially if they have a history of acute chest syndrome or pulmonary hypertension¹⁴.
Choice D reason: This is correct. Drinking plenty of fluids when outside in hot weather is important for people with sickle cell anemia, as dehydration can cause the red blood cells to sickle and block blood vessels. Staying hydrated can help prevent or reduce the severity of sickle cell crises¹⁵.

Correct Answer is D
Explanation
Choice A reason: Vitamin B12 does not contribute to the increased production of RBCs after significant blood loss. Vitamin B12 is a type of vitamin that is essential for the normal formation and maturation of red blood cells (RBCs), which carry oxygen throughout the body. ¹ However, vitamin B12 does not increase the production of RBCs in response to blood loss. That is the role of erythropoietin, a hormone that stimulates the bone marrow to produce more RBCs. ²
Choice B reason: Vitamin B12 is not needed to prevent excessive production of red blood cells. Vitamin B12 is needed for the normal production of red blood cells, not for the prevention of overproduction. Excessive production of red blood cells, also known as polycythemia, can cause the blood to become thick and viscous, increasing the risk of clotting and stroke. ³ Polycythemia can be caused by various factors, such as smoking, dehydration, or genetic mutations, but not by a lack of vitamin B12.
Choice C reason: Vitamin B12 is not needed to prevent RBCs from sticking together. Vitamin B12 is needed for the normal formation and maturation of RBCs, not for the prevention of aggregation. RBCs can stick together and form clumps, also known as rouleaux, which can impair blood flow and oxygen delivery. Rouleaux can be caused by various factors, such as inflammation, infection, or cancer, but not by a lack of vitamin B12.
Choice D reason: Vitamin B12 is needed for the normal formation and maturation of RBCs, but it cannot be absorbed by the body without a substance called intrinsic factor. Intrinsic factor is a protein that is produced by the stomach and binds to vitamin B12, allowing it to be absorbed by the small intestine. ¹ Pernicious anemia is a type of anemia that occurs when the stomach does not produce enough intrinsic factor, leading to vitamin B12 deficiency. The only way to treat pernicious anemia is by giving vitamin B12 injections, which bypass the need for intrinsic factor.
Correct Answer is D
Explanation
hoice A reason: Preparing for endotracheal intubation and ventilatory support is not the action that the nurse should take for a client with thyroid storm. This intervention is indicated for clients with respiratory failure or impending airway obstruction, which are not the case for this client.
Choice B reason: Providing continuous sedation for pain relief is not the action that the nurse should take for a client with thyroid storm. This intervention may worsen the client's condition by suppressing the respiratory drive and lowering the blood pressure. The nurse should administer antithyroid medications, beta blockers, and corticosteroids as prescribed to reduce the thyroid hormone levels and the associated symptoms.
Choice C reason: Initiating cardiac monitoring and assessing for reflex bradycardia is not the action that the nurse should take for a client with thyroid storm. This intervention is indicated for clients with hyperkalemia or digoxin toxicity, which are not the case for this client. The nurse should monitor the client's heart rate and rhythm, but not expect a reflex bradycardia, which is a paradoxical slowing of the heart rate in response to a rapid rise in blood pressure.
Choice D reason: Maintaining IV fluid infusion and assessing adequacy of hydration is the action that the nurse should take for a client with thyroid storm. This intervention is indicated for clients with thyroid storm, as they are at risk of dehydration and electrolyte imbalance due to increased metabolic rate, fever, sweating, vomiting, and diarrhea. The nurse should administer isotonic fluids, such as normal saline, and monitor the client's fluid intake and output, urine specific gravity, and serum electrolytes.
