The nurse is working in an outpatient clinic. The clinic has been alerted that there is an outbreak of tuberculosis (TB). Which of the following clients entering the clinic today are most likely to have TB?
A 33-year-old daycare worker at a high-risk center.
A 54-year-old nurse working in a nursing home.
A 16-year-old female high school student.
A 43-year-old homeless man with a history of alcoholism.
The Correct Answer is D
A. While daycare workers can be at risk for various infections, they are not typically considered at high risk for TB unless they are in close contact with TB-positive individuals. Therefore, this option does not present the highest likelihood of TB.
B. This individual is at a moderate risk for TB, especially if they are caring for patients with known TB or are in an environment where TB may be more prevalent. However, nursing homes are more often associated with other infections rather than being primary sources for TB outbreaks.
C. High school students are generally not at high risk for TB unless they have specific exposure or travel history. Without additional risk factors, this group does not exhibit a high likelihood of TB.
D. This option represents the highest likelihood of TB. Homeless individuals are at increased risk for TB due to factors such as crowded living conditions, poor nutrition, and lack of access to healthcare.

Correct Answer is B
Explanation
A. Topical corticosteroids are not typically used for impetigo, as it's a bacterial infection.
B. Impetigo is highly contagious, so contact precautions are essential to prevent the spread of infection. This includes wearing gloves and a gown when providing direct care, and using dedicated equipment for the child.
C. A wood lamp is used to examine the skin for fungal infections, not bacterial infections like impetigo.
D. Impetigo typically doesn't require dressings. If dressings are used, they should be removed gently to avoid further skin damage.
Correct Answer is ["C","E"]
Explanation
A. Encouraging a child with hypoglycemia to ambulate can be dangerous. Physical activity can further lower blood sugar levels, which could exacerbate the situation. It’s better to keep the child stable and provide treatment for the low blood sugar.
B. Waiting to confirm the blood glucose reading is not appropriate in this case. A blood glucose level of 50 mg/dL requires immediate intervention, not a delay. The priority is to treat the hypoglycemia right away.
C. Providing a fast-acting carbohydrate, like a tablespoon of honey, is an appropriate intervention for treating hypoglycemia. Other options could include glucose tablets or juice. The key is to quickly raise the blood sugar level.
D. Administering insulin when blood glucose levels are low is contraindicated. Insulin would further decrease the blood sugar level, worsening the hypoglycemic state. The priority is to treat the low blood sugar, not to give insulin.
E. If the child becomes unconscious due to hypoglycemia and is unable to swallow, glucagon should be prepared for administration. Glucagon can help raise blood sugar levels in emergency situations.
