A nurse is preparing to insert an indwelling urinary catheter for a client.
Which of the following actions should the nurse take first?
Attach a prefilled syringe to the catheter inflation hub.
Position the sterile drape leaving the perineum exposed.
Cleanse the client's meatus with antiseptic solution.
Lubricate the catheter with water-soluble gel.
The Correct Answer is C
Choice A rationale:
Attaching a prefilled syringe to the catheter inflation hub is a step performed after the catheter insertion to inflate the balloon, securing the catheter in the bladder. This action is not the first step and should not be done before cleansing the meatus and positioning the sterile drape.
Choice B rationale:
Positioning the sterile drape leaving the perineum exposed is a necessary step in maintaining the sterility of the procedure area. However, it is not the first action the nurse should take. Cleaning the client's meatus with an antiseptic solution is the initial step to prevent infection during catheter insertion.
Choice C rationale:
Cleaning the client's meatus with antiseptic solution is the first step in inserting an indwelling urinary catheter. This action helps to reduce the risk of urinary tract infection by minimizing the introduction of bacteria into the urethra.
Choice D rationale:
Lubricating the catheter with water-soluble gel is a step performed after cleansing the meatus and positioning the sterile drape. It facilitates the smooth insertion of the catheter into the urethra. However, it is not the first action to be taken.

Correct Answer is B
Explanation
- A. This choice is incorrect because forgetting to buy a gift is not an example of dissociation, but rather a sign of poor memory or lack of attention.
- B. This choice is correct because describing the abuse as if it happened to someone else is an example of dissociation, which is a defense mechanism that involves separating oneself from painful or traumatic experiences.
- C. This choice is incorrect because being verbally assertive is not an example of dissociation, but rather a personality trait or a coping skill.
- D. This choice is incorrect because blaming the boss for not getting a promotion is not an example of dissociation, but rather a sign of external locus of control or rationalization.
Correct Answer is A
Explanation
- A is correct because aPTT (activated partial thromboplastin time) measures the effectiveness of heparin therapy and guides dosage adjustments.
- B is incorrect because PT (prothrombin time) measures the effectiveness of warfarin therapy, not heparin.
- C is incorrect because INR (international normalized ratio) is a standardized version of PT that also monitors warfarin therapy, not heparin.
- D is incorrect because WBC count (white blood cell count) measures the body's immune response and has no relation to heparin therapy.
