Answer: in the above example, cancer is an independent variable.
Explanation:
Based on the information given, we can infer that the dependent variable is cancer. Cancer is not the independent variable.
The extent to which an individual smokes is.an independent variable, duration of smoking, smoker's age can all be identified as the independent variable.
Cancer is not a independent variable here, in our study cancer is dependent on the amount of smoking by an individual.So, it is a dependent variable.
Answer:
D. WBC count
Explanation:
First, let's define symptom and sign.
A <u>symptom</u> is some sort of evidence that could suggest a disease or disorder, but it must be observed and noticed by the patient. Basically, it's what the patient feels.
So, a headache, pain, and nausea are all symptoms.
A <u>sign </u>is evidence that someone else observes or collects. So, a family member or doctor sees signs.
Therefore, temperature, white blood cell count, and pulse are all signs.
The question asks us which is a sign, not a symptom. Therefore, the best choice is D. WBC count
Answer: True
Explanation:
Misattribution happens when we remember something but fail to remember the source of the information.
The source of the information could be details like the time, the place and the person that is involved.
Someone could get an information from a friend, say Peter but when he remembers the information, he fails to remember the source of the information and attributes it to some other source.
The Scenario:
A nursing assistant has entered a scene where a blood spill has occurred.

The nursing assistant did not call the lead nurse to report the incident prior to cleaning.
COPD, emphysema, bronchitis , and asthma. Chronic obstructive pulmonary disease (COPD), which incorporates chronic bronchitis.
<h3>What about chronic obstructive pulmonary disease?</h3>
- COPD symptoms include persistent coughing or wheezing.
- Excessive sputum or phlegm.
- Respiration difficulty.
- The signs and symptoms include wheezing, expulsion mucus (sputum), and trouble breathing.
- It's frequently brought on by prolonged exposure to irritant gases or particulates, most often from cigarette smoke.
- Heart disease, carcinoma , and a variety of other diseases are more likely to occur in people with COPD.
- In around 9 out of each 10 cases, smoking is regarded to be the first cause of COPD.
- The lining of the lungs and airways can get damaged by the toxic compounds in smoke.
- Quitting smoking can help stop the deterioration of COPD.
- Short-acting bronchodilator inhalers are the initial line of therapy for the bulk of COPD patients.
- Breathing is formed easier by bronchodilators, which relax and expand the airways.
- Short-acting bronchodilator inhalers are available in two varieties: beta-2 agonist inhalers, like salbutamol and terbutaline.
- For those with chronic obstructive pulmonary disease (COPD) who have (or are in danger for) hypercapnia, an excessive amount of oxygen can be harmful.
- Patients with hypercapnia are frequently over oxygenated, despite established standards and acknowledged danger.
