The nurse is sitting at the desk watching the telemetry monitors and notes a patient's rhythm suddenly shows asystole. Which action should the nurse take first?

Quantitative research involves the collection and analysis of numerical data to answer research questions and test hypotheses. Statistical methods are used to analyze the data and draw conclusions about relationships, differences, or effects.

A. "Quantitative research aims to understand the feelings associated with a particular event":

This statement is incorrect. Quantitative research focuses on measurable data and is concerned with objective observations rather than subjective feelings or experiences.

B. "Qualitative research studies how to implement EBP into various settings":

This statement is incorrect. Qualitative research explores subjective experiences, perceptions, and meanings to gain a deeper understanding of phenomena. It is not specifically focused on implementing evidence-based practice (EBP) into various settings.

D. "Qualitative research uses larger sample sizes than quantitative research":

This statement is incorrect. Qualitative research typically involves smaller sample sizes compared to quantitative research. The emphasis in qualitative research is on depth and richness of data rather than statistical generalizability.

A. "I will take my warfarin with a glass of water the night before my surgery":

This statement indicates a need for further teaching. Warfarin is an anticoagulant medication, and it should typically be discontinued or adjusted before surgery to reduce the risk of excessive bleeding. Taking it the night before surgery could increase the risk of bleeding during the procedure.

B. "I understand what risks I can expect with this surgery":

This statement suggests that the client has received information about the risks associated with the surgery, which is an essential component of preoperative education. There is no indication for further teaching based on this statement.

C. "I will take time to relax if I get nervous the night before surgery":

This statement demonstrates the client's awareness of the importance of managing stress and anxiety before surgery, which is a positive coping strategy. There is no need for further teaching based on this statement.

D. "I will have a glass of water the morning of my surgery":

This statement is generally acceptable. Clear fluids may be allowed up to a certain time before surgery, depending on the facility's protocol. However, specific instructions regarding fasting before surgery should be clarified with the healthcare provider or surgical team to ensure adherence to preoperative guidelines.
