A nurse who serves on an infection control committee is assessing the adequacy of environmental controls against infection.
What does the nurse know to be the first line of defense in medical asepsis?
Isolation or barrier procedures.
Standard precautions.
Hand hygiene techniques.
Routine cleaning of client rooms.
The Correct Answer is C
Hand hygiene techniques are the first line of defense in medical asepsis because they prevent the transmission of microorganisms from one person or object to another. Hand hygiene techniques include washing hands with soap and water or using an alcohol-based handrub.
Choice A is wrong because isolation or barrier procedures are not the first line of defense in medical asepsis, but rather a way of preventing the spread of infection to other patients or health care workers when a patient has a known or suspected infection.
Choice b is wrong because the nature of detergent used on the unit is not the first line of defense in medical asepsis, but rather a factor that affects the effectiveness of cleaning and disinfection of surfaces and equipment.
Choice D is wrong because the ventilation system type is not the first line of defense in medical asepsis, but rather a factor that affects the quality of air and the risk of airborne transmission of microorganisms.

Correct Answer is B
Explanation
This outcome indicates that the client has resolved their constipation and has a regular pattern of defecation without difficulty or discomfort.
Choice A is wrong because taking a laxative daily can worsen constipation by causing dependency and reducing the natural peristalsis of the colon.
Choice C is wrong because requesting a bedpan every four hours does not necessarily mean that the client has bowel movements. It may indicate that the client has difficulty passing stool or has a sensation of incomplete emptying.
Choice D is wrong because having a bowel movement within 72 hours is still considered constipation. Constipation is diagnosed when bowel movements are associated with at least two of the following symptoms, occurring in the past three months with an onset of symptoms of at least six months: Less than three spontaneous bowel movements per week, Lumpy or hard stools from at least 25% of bowel movements.
Correct Answer is A
Explanation
Insert a sterile needle and aspirate 3 to 5 mL of urine into the syringe. This is the best technique for obtaining a sterile urine specimen from an indwelling urinary catheter because it ensures that microorganisms in the specimen are from the urine, and not the result of contamination.
Choice B is wrong because it does not use sterile technique and it does not collect fresh urine. The urine in the drainage bag may have been sitting there for a long time and may not reflect the current condition of the patient’s urinary tract.
Choice C is wrong because it does not use sterile technique and it flushes the catheter with sterile water, which may dilute the urine and alter its composition.
Choice D is wrong because it does not use sterile technique and it collects urine from the drainage bag, which may be contaminated or stale.
