A nurse is caring for a client who is scheduled for surgical repair of a femur fracture and has a prescription for lorazepam preoperatively. Which of the following statements made by the client should indicate to the nurse that the medication has been effective?

(A) "I’ll breathe deeply and cough every 4 hours."
Deep breathing and coughing exercises should be done more frequently, typically every 1-2 hours while awake, to help prevent respiratory complications such as atelectasis and pneumonia.

(B) "I’ll splint my incision with a pillow to cough."
This statement indicates an understanding of the instructions. Splinting the incision with a pillow helps support the surgical site, reduces pain, and makes coughing more effective and less uncomfortable. This technique is important for clients to use to help clear secretions from the lungs postoperatively.

(C) "I’ll start to use the incentive spirometer when I can get out of bed."
The use of an incentive spirometer should begin as soon as possible, usually while the client is still in bed, to encourage deep breathing and prevent postoperative respiratory complications. It should not be delayed until the client can get out of bed.

(D) "I’ll lie flat in bed to cough and deep breathe."
Lying flat is not the optimal position for deep breathing and coughing exercises, as it can make it more difficult to fully expand the lungs. The client should be positioned with the head of the bed elevated or sitting up to facilitate better lung expansion and more effective coughing.

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.
