go through the following document.

Let data be a dataset having 4 columns.
For example data =
87, 29, 10, 88
93, 95, 40, 67
55, 98, 27, 96
15, 34, 78, 23
12, 58, 11, 20
68, 65, 93, 11
…
Answer the following questions using Python commands.
Your answers must work on any dataset that has 4 columns and not only on the one provided above.
(a) Select all of row 0: [87, 29, 10, 88].
I am giving you the answer to the first question:
data[0, :]
(b) Select all of column 3: [88, 67, 96, 23, 20, 11].
(c) Select all of rows 2, 3, and 4:
55, 98, 27, 96
15, 34, 78, 23
12, 58, 11, 20.
(d) Find the maximum value in column 3. For the given example, the value is 96.
(e) Find the row index of the maximum value in column 3. For the given example the output is 2.
(f) Select the entire row that contains the maximum value for column 3. For the given example, the row is [55, 98, 27, 96].
(g) Store the values of column 1 in a variable named col1.
(h) Using the variable col1, select all the values in column 1 that are greater than 50: [95, 98, 58, 65].
(i) Using the variable col1, select all the values in column 1 that are greater than 50 and smaller than 90: [58, 65].
(j) Display the entire data set sorted on column 1. For the given example, the output is
87, 29, 10, 88
15, 34, 78, 23
12, 58, 11, 20
68, 65, 93, 11

The wound began when the patient was bit by her cat when she accidentally stepped on the cats tail. The wound is malodorous. The patients medical history includes HTN and she has had a hysterectomy 2 years ago due to cancer. She completed her round of chemotherapy and radiation and has been cancer free for over a year. She is allergic to Sulfa drugs and iodine, she is allergic to shellfish, avocados, papaya and walnuts. Follow the ADPIE process and answer the following questions: 1. What is your priority assessment for this patient and why? a. What other priorities are there for a patient returning from surgery? Why? 2. What would be the priority nursing diagnosis (or nursing problem) for this patient? a. Explain your rationales. 3. What plan do you have for this patient? a. What members of the interdisciplinary team do you need to have involved with this patients care? b. What is the significance of this patients allergies? c. What consultation might you ask the provider for? 4. How would you implement your plan for this patient? a. Who else do you involve in the implementation besides those you listed above? 5. How do you evaluate if you plan of care is successful or effective? a. Remember: SMART goals Case Study #2 You are a nurse at a university student health center. A 21 year old male patient who is a junior at the university comes to the clinic and complains of having a high temperature, frequent productive cough, and states his chest feels tight. He also states he had been drinking a lot over the past few weeks because he is stressed out about finals. His records indicate a previous appendectomy, allergies to ragweed and dogs.
