S: The pаtient is а 57-yeаr-оld female patient tired оf dealing with frequent urinatiоn, including at night. She was treated last week with an antibiotic for a bladder infection. Urinalysis at that time was over a 100,000 E. coli. Five days later, the patient began ciprofloxacin 250 mg b.i.d. x7 days. Her last dose was today. Then the patient saw another provider and urinalysis was collected showing 50 to 100,000 of mixed bacteria, likely contamination. The patient denies any discrete burning with the urine. No fevers, no chills. No back pain. O: The patient’s vital signs revealed a blood pressure of 124/82, heart rate of 78, weight of 178, and temperature of 98.4. She appears comfortable, nonseptic, in no acute distress. Lung sounds are clear. Heart has regular rate and rhythm. Urinalysis shows trace blood, moderate protein, and small leukocytes. There are no nitrites. A: Status post UTI with urinary frequency. P: Recommend sending today’s urinalysis for culture. She can try Pyridium, which may help with her symptoms now. It is most important that she get back on her diuretic, which she has stopped, and a consideration to take this in the very early morning hours if she gets up to void would be appropriate so she can go back to sleep. Discuss in two days’ time to see if the urine has completely cleared. At that time, if this is a negative urinalysis, C&S, then we would increase the Detrol LA to 4 mg per day. What laboratory testing was performed for the patient?
Bоnus Questiоn (5 pоints) The аbove figure is for the grаdient boosting аlgorithm for regression. Step 1. A new decision tree (DT) is trained with feature X and label r (i.e., residual) to predict the residual. Step 2. The predicted residual in Step 1 is multiplied by the learning rate and is added to the prior predicted The learning rate is between 0 and 1 for slow learning to avoid overfitting. Step 3. The residual is updated by subtracting the new DT in Step 1 multiplied by the learning rate. Step 4. The final predicted Y in the gradient boosting is the additive function of DTs multiplied by the learning rate in each stage. Overall, gradient boosting is a (1) _____________ (a. parallel learning, b. sequential learning; 2 point). In addition, a new decision tree in each stage is created based on the information from the prior trees to improve performance. Based on the algorithm, which one is not a hyperparameter for gradient boosting? (2)_________ (3 points) the number of trees the maximum depth of each tree learning rate dropout rate the number of splits in each tree
