A nurse is preparing to obtain a blood specimen from a client's central venous access device. Prior to collecting the specimen, the nurse should clean the connection thoroughly with which of the following antiseptics?
Povidone-iodine
Hydrogen peroxide
2% chlorhexidine
70% alcohol solution
The Correct Answer is C
A. Povidone-iodine: Although effective for skin disinfection, povidone-iodine requires a long drying time and is not the preferred agent for disinfecting the access port of central lines. It is more commonly used for preparing the skin before catheter insertion, not for port access.
B. Hydrogen peroxide: Hydrogen peroxide is not recommended for disinfecting central venous access devices due to its cytotoxic properties and potential to damage catheter materials. It can also irritate tissue and is not effective against all organisms.
C. 2% chlorhexidine: Chlorhexidine is the preferred antiseptic for disinfecting central venous catheter ports. It offers rapid, broad-spectrum antimicrobial action and prolonged residual activity, making it ideal for preventing catheter-related bloodstream infections.
D. 70% alcohol solution: Alcohol is commonly used but lacks the persistent antimicrobial activity of chlorhexidine. While it can reduce surface microbes, it is less effective at preventing infection over time compared to 2% chlorhexidine.

Correct Answer is B,D,C,A
Explanation
Progressive discipline begins with a verbal warning to make the employee aware of performance concerns. If the behavior persists, the next step is a written reprimand outlining expectations and deadlines for improvement. Continued issues lead to a suspension, which serves as a final warning. If no improvement occurs, termination of employment is the final step.
Correct Answer is A
Explanation
A. Abdominal distention: Paralytic ileus is a temporary cessation of bowel motility, often following surgery, especially abdominal or orthopedic procedures. Distention occurs due to accumulation of gas and fluid in the intestines and is a key indicator.
B. Oliguria: Reduced urine output may suggest dehydration or kidney issues but is not specific to paralytic ileus. It does not directly reflect gastrointestinal motility or function.
C. Dizziness: Dizziness can result from various causes like blood loss, medication, or orthostatic hypotension, but it is not a clinical sign of paralytic ileus and does not relate to bowel activity.
D. Watery stool: Watery or loose stools are more characteristic of diarrhea or bowel irritation. In paralytic ileus, bowel movement is typically absent, and stool passage is minimal or stopped.
