A 42-yr-old patient admitted with acute kidney injury due to dehydration has oliguria, anemia, and hyperkalemia. Which prescribed action should the nurse take first?

A 70-year-client presents to the emergency department from an assisted living facility with chest pain that started 90 minutes ago. The client’s medical history is significant for a stroke, osteoarthritis, sleep apnea on continuous positive airways pressure (CPAP), systolic heart failure with ischemic cardiomyopathy, stage 3 chronic renal disease, hypertension, type 2 diabetes mellitus, glaucoma, and diabetic neuropathy. The health care provider prescribes a nitroglycerin continuous drip at 5 mcg/min to treat the chest pain, with directions to titrate to chest-pain free. The nurse assesses the client, administers the nitroglycerin continuous drip, monitors the client’s vital signs, and documents in the nurses’ notes.

Suppose you were interested in conducting a study examining how ratings of similarity between oneself and another person were related to how attracted one is to the other person. You conduct this study by giving participants a description of a person named “Sarah.” Participants are asked to read the description and then rate on a scale from 1 to 10 how similar Sarah is to themselves (X). You also ask each participant to rate on a scale from 1 to 20 how likeable they think Sarah is (Y). The data from five participants is presented below. Individual X Y 1 2 5 2 7 5 3 6 19 4 1 5 5 6 20 What is the correlation coefficient between similarity (X) and likability (Y)? **Report your answer to 4 decimal places.

For a perfect positive linear relationship, the z scores for the Y and X variables will tend to have _____.

The strength of the relationship in a correlational analysis can be calculated with
