Grading Rubric Advice and Sample Table for This Discussion Question

Class after completing the assigned reading, reflect on it and answer the discussion question. Use the readings and other current scholarly sources to answer the question, no use of consumer web sites or blogs. APA and Academic writing posit use of references that are less than five years old. If a topic has little information available, one can expand the search to 7 and then to 10 years. This topic has a great deal of information available so I will expect current sources.

Comment 1

If you are trying to decide whether to use a z-test or a t-test, you are trying to determine how well your sample size represents the entire population. A larger sample size will better represent the entire population to a certain point because after a certain size, t and z distributions begin to look the same. If a sample size is to small it will be less representative of the entire population and it is more likely to either miss characteristics of the entire population or over emphasize characteristics. There are different critical values for distributions t and z (Foltz, 2012).

The z-test chart would be best to use with sample sizes over 30 and represents what is considered a normal distribution. If you want to know how many people in a school scored over 95 on a test and you know the average is 85 with a standard deviation of 15, and you take a sample size of 40 people, this would be a good time to use the z-test (Foltz, 2012).

The t-test chart would be best to use with smaller sample sizes and allows greater room for error. The distribution of the t-test curve is more platykurtic when compared to normal distribution or the curve for the z-test. If you wanted to know how many people in a school scored over 95 on a test and you know the average is 85 with a standard deviation of 15, and you take a sample size of 20 people, this would be a good time to use the t-test. The benefit of using the t-distribution is that you can use a smaller sample size with the understanding that there may be a greater margin of error (Foltz, 2012).

It may also be appropriate to use the t-test if the population standard deviation is unknown (Grove & Cipher, 2017).

Comment2

Z-test and T-test are methods for hypothesis testing (which is the main goal of statistics). Hypothesis testing determines which statements about the population is most reliable based on data available.

For example, a hypothesis that claims those individuals who take Airborne regularly are less likely to become sick during influenza season than those who do not take the supplement. A hypothesis test can be done by giving sample (sample of 40 individuals for instance) doses of Airborne for a certain period of time compared to a control group.

Z-test is utilized for larger set of data or when sample size is greater than 30 (n ≥ 30). Based on the previous example, there were 40 individuals mentioned. Therefore, Z-test is more appropriate to use over T-test. Z-test is done to compare two groups when population variance (standard deviations) are known. Therefore, when standard deviation is known, z-core can be calculated. With normal distribution, researcher can determine probabilities using mean from the sample. This method allows researcher to compare scores from different normal distributions.

Sometimes, samples are small so T-tests are used. T-test is more applicable when participants are less than 30 (n ≤ 30). T-test is applicable when standard deviation is not known and when certain data sets are not suited for analysis using normal distribution. While z-test follows normal distribution, t-test follows t-distribution (or Student’s t-distribution).

This is the case study:

Max Points: 20.0

Use the following Case Scenario, Subjective Data, and Objective Data to answer the Critical Thinking Questions.

Case Scenario

Mrs. J. is a 63-year-old woman who has a history of hypertension, chronic heart failure, and sleep apnea. She has been smoking two packs of cigarettes a day for 40 years and has refused to quit. Three days ago, she had an onset of flu with fever, pharyngitis, and malaise. She has not taken her antihypertensive medications or her medications to control her heart failure for 4 days. Today, she has been admitted to the hospital ICU with acute decompensated heart failure.

Subjective Data

1. Is very anxious and asks whether she is going to die.
2. Denies pain but says she feels like she cannot get enough air.
3. Says her heart feels like it is “running away.”
4. Reports that she is so exhausted she cannot eat or drink by herself.

Objective Data

1. Height 175 cm; Weight 95.5 kg
2. Vital signs: T 37.6 C, HR 118 and irregular, RR 34, BP 90/58
3. Cardiovascular: Distant S1, S2, S3 present; PMI at sixth ICS and faint; all peripheral pulses are 1+; bilateral jugular vein distention; initial cardiac monitoring indicates a ventricular rate of 132 and atrial fibrillation
4. Respiratory: Pulmonary crackles; decreased breath sounds right lower lobe; coughing frothy blood-tinged sputum; SpO2 82%
5. Gastrointestinal: BS present: hepatomegaly 4 cm below costal margin

Critical Thinking Questions

What nursing interventions are appropriate for Mrs. J. at the time of her admission? Drug therapy is started for Mrs. J. to control her symptoms. What is the rationale for the administration of each of the following medications?

1. IV furosemide (Lasix)
2. Enalapril (Vasotec)
3. Metoprolol (Lopressor)
4. IV morphine sulphate (Morphine)

Describe four cardiovascular conditions that may lead to heart failure and what can be done in the form of medical/nursing interventions to prevent the development of heart failure in each condition.

Taking into consideration the fact that most mature adults take at least six prescription medications, discuss four nursing interventions that can help prevent problems caused by multiple drug interactions in older patients. Provide rationale for each of the interventions you recommend.

By day 2 (Tuesday) post a brief description of how epidemiology can be used to evaluate health services. Then describe an example of an epidemiological study that has been used to evaluate a screening program, include the methodological issues that an epidemiologist may face while conducting these epidemiological studies. Your post must be written in APA format.
