Which of the following factors are known to commonly trigger a crisis in patients with sickle cell disease? (Select all that apply)
Airplane flights
Dehydration
Cold weather
Illness
Flashing light patterns on television
Correct Answer : A,B,C,D
A. Airplane flights can trigger a crisis due to changes in altitude and decreased oxygen levels in the cabin. The lower atmospheric pressure and reduced oxygen can contribute to sickling of red blood cells, increasing the risk of a crisis.
B. Dehydration is a significant trigger for sickle cell crises. It can lead to hemoconcentration, making the blood more viscous and promoting sickling of the red blood cells. Maintaining hydration is crucial for preventing crises.
C. Exposure to cold weather can trigger vaso-occlusive crises in sickle cell patients. Cold temperatures can cause blood vessels to constrict, reducing blood flow and increasing the likelihood of sickling and pain episodes.
D. Any illness, particularly infections, can trigger a sickle cell crisis. Infections can lead to increased metabolic demand, dehydration, and inflammatory responses, all of which can contribute to vaso- occlusion and pain.
E. While certain sensory stimuli can affect individuals with various conditions (like migraines), flashing light patterns on television are not commonly recognized triggers for a sickle cell crisis. There is no substantial evidence linking this to vaso-occlusive events in sickle cell disease.

Correct Answer is D
Explanation
A. Neutropenia refers to an abnormally low level of neutrophils in the blood. This condition can result from various factors, including severe infections, bone marrow issues, or certain medications. However, in the context of a severe bacterial infection, you would expect an increase in neutrophils, not a decrease.
B. Anemia is a condition characterized by a lack of healthy red blood cells to carry adequate oxygen to the body’s tissues. While infections can lead to anemia, it is not a direct indicator of white blood cell production or response to a bacterial infection.
C. Leukopenia refers to a decrease in the overall white blood cell count. Like neutropenia, it indicates a reduced ability to fight infection, which is not consistent with a severe bacterial infection where the body is actively trying to produce more white blood cells.
D. A "left shift" indicates the presence of increased immature neutrophils (such as band cells) in the blood, which occurs when the bone marrow releases these cells into circulation in response to a severe infection. This reflects the body’s effort to combat an infection, typically seen in bacterial infections.
Correct Answer is ["B","C","D","F"]
Explanation
A. While it's important for older adults to have regular blood tests to monitor their health, showing expected changes in white blood cell counts is not a specific risk factor for infections.
B. Skin tests for tuberculosis may be falsely negative in older adults due to a weakened immune response.
C. Older adults should stay up-to-date on their vaccinations, including influenza, pneumococcal, and shingles vaccinations, to help protect themselves against these infections.
D. Older adults are at increased risk for respiratory tract infections, such as pneumonia, and genitourinary infections, such as urinary tract infections.
E. Booster vaccinations are essential for older adults to maintain protection against diseases such as influenza, tetanus, diphtheria, and pertussis.
F. Older adults may not develop a fever in response to a severe infection. This can make it difficult to recognize the presence of an infection.
