Suppose an unrelated 82-year-old man, 72-year-old woman and 77-year-old man are selected from a community.

What is the probability that exactly one of the three people has Alzheimer's disease?

Problem 4.

(problem 5.23 page 74) A company‘s management is worried about employee drug

use and is instituting a policy of mandatory drug test. If an employee is a drug user, there is an 85%

chance that he or she will test positive. If the employee is not a drug user, there is 95% chance that

he or she will test negative. Individuals who test positive are fired. We don‘t know the fraction of

employees who are drug users. We do know, however that 10% of all employees tested positive.

a. What fraction of employees are drug users?

b. Of those who tested positive, what fraction are in fact not drug users?

You have been assigned to care for Mr. Alvarez, a 74-year-old client being treated for a urinary tract infection. He suffered a cerebrovascular accident (stroke) 6 months ago and has had difficulty ambulating and attending to his own needs because of right-sided weakness. He is thin for height, incontinent of foul smelling urine, and has non-blanchable erythema on his coccyx and peritoneal area. He is alert and oriented to person, place, and time. He has decreased sensation on his entire right side. He spends most of his time in bed or sitting in a chair.

1.What data suggests that Mr. Alvarez is particularly vulnerable to pressure sore development?

2 What additional information does the nurse need in order to use the Braden Scale to determine his potential for pressure injury development?

3.How should the nurse stage the noted areas of erythema?

4.Based on the information provided in the case scenario, what nursing diagnoses are appropriate for this patient?

5.What independent nursing interventions can the nurse provide to protect him from further skin breakdown?

Scenario: A 74-year-old male, retired accountant, with a long-standing history of hypertension and atherosclerosis, begins to exhibit some personality changes, deterioration in grooming, trouble understanding news events, and difficulty managing personal finances.

His wife of 50 years becomes concerned and schedules an appointment with his healthcare provider, who diagnoses him with Vascular Dementia, Alzheimer’s type. Arrangements have been made for a visiting RN to come to the house once weekly. Initial Discussion Post: Address the following: In what stage of Alzheimer’s disease is this client? What criteria did you use to determine this? What are 3 priority RN assessments when home visits are made? What are some anticipated caregiver issues that this client’s spouse will personally experience? List and describe 3 intercollaborative referrals that may be needed for this client within the next year or so.

Patient introduction: F. E. is a 74-year-old woman who comes to the medical clinic with concerns related to various “spots” on

her face. She says they have been there for a while and she thought they were just “age spots” but got

concerned after her friend was diagnosed with malignant melanoma.

CASE STUDY PARKINSON’S DISEASE

Miss Rose is a 74-year-old female, who is a retired widow and lives with her son for the past five years. Both enjoy planting seedlings and own a community agriculture store. She does not suffer with hypertension or diabetes and has an active lifestyle. She is also not known to have any psychiatric illnesses. Over the past six months Miss Rose’s son and herself noticed physical changes and decided to visit her General Practitioner. At her visit she mentioned to the doctor that she was having difficulty rising from a sitting position after grooming her plants or turning from one table to another when she has customers. Documentation on her clinic file noted that she previously complained of difficulty walking and falling when coming out of bed. She was sent for an X-ray but there were no clinical findings. The physician asked her to describe what happened when she fell. Miss Rose verbalized that when she got up from bed and starting walking, she started moving forward and backward then stooped forward with small fast steps and then she fell. Her son mentioned to the doctor that he has noticed that when she is pruning her plants, she has abnormal rhythmic movement of the upper and lower limbs. She occasionally has a slight limp, and her handwriting has become smaller over the past months. This has stopped her from doing her daily yoga exercises and she has been very disturbed about it. Miss Rose then further explained that the movement started on the distal part of both upper limbs at the same time. She also expressed that during rest she noticed the movement in her limbs and as she started her tasks the movements became more aggravated. Urinary incontinence is also a problem for Miss Rose, and she is having difficulty in her swift movements to her bathroom. The patient was later diagnosed with Parkinson’s disease.

After the assessment and interview of Miss Rose the Physician documented the following: Physical Assessment Vital Signs: BP- 130/74 mmHg Temperature - 36.7 C, Pulse- 78 bpm regular and bounding Respiration- 20 bpm Height- 5ft 7 in Weight- 70 kg Facial expression- Masklike Gait- Shuffling gait with tendency to fall forward and backward CNS Examination Alert and oriented to time, person and place Level of consciousness GCS- 15/15 Sleeping patterns- normal Swallowing gag reflex- normal Cogwheel rigidity present Tremor present Bradykinesia present Dysphonia present

10.2.9

An article in Radio Engineering and Electronic Physics (1980, Vol. 25, pp. 74-79) investigated the behavior of a stochastic generator in the presence of external noise. The number of periods was measured in a sample of 100 trains for each of two different levels of noise voltage, 100 and 150 mV. For 100 mV, the mean number of periods in a train was 7.9 with s₁ = 2.6. For 150 mV, the mean was 6.9 with s₂ = 2.4.

Use α = 0.01 and assume that each population is normally distributed and the two population variances are equal.

(a) It was originally suspected that raising noise voltage would reduce mean number of periods. Do the data support this claim?Choose the answer from the menu in accordance to the question statementChoose the answer from the menu in accordance to the question statement
