A nurse is instructing a client on how to obtain a clean catch urine specimen. Which of the following statements by the client indicates understanding of the teaching?
I can collect my urine in the morning and drop it off in the lab in the evening.
I thoroughly cleanse the urethral meatus.
As soon as I begin urinating, I will start to collect the sample.
I can't collect a urine sample when I am menstruating.
The Correct Answer is B
Choice A rationale
Collecting the urine in the morning and dropping it off in the lab in the evening is incorrect because the specimen must be delivered promptly to the laboratory, typically within one hour, or refrigerated immediately to maintain sample integrity. Prolonged time or warm temperatures allow bacteria to multiply, leading to inaccurate culture results and potentially inappropriate diagnosis or treatment.
Choice B rationale
Thoroughly cleansing the urethral meatus is the critical initial step in obtaining a clean catch specimen, as this reduces the risk of contamination from normal flora and external debris. Using an antiseptic wipe to clean the area before urination ensures that the collected urine sample reflects the true microbial contents of the bladder and not contaminants from the skin surface.
Choice C rationale
Starting to collect the sample as soon as urination begins is incorrect because the initial urine flow should be voided into the toilet to flush out microorganisms residing in the distal urethra. The specimen should be collected from the midstream portion of the flow, ensuring that the collected sample is representative of the urine inside the bladder and minimizes external contamination.
Choice D rationale
Stating that a urine sample cannot be collected during menstruation is inaccurate, as a clean catch specimen can still be obtained, although careful cleansing is even more vital to prevent contamination with blood. While menstruation can complicate urinalysis interpretation, a clean catch midstream sample is often still feasible and necessary for culture or other analyses.

Correct Answer is C
Explanation
Choice A rationale
Elevated temperature (fever) is a sign of an infectious or inflammatory process, which typically increases the metabolic demand and often leads to a compensatory increase in heart rate (tachycardia), not a decrease (bradycardia). Bradycardia, defined as a heart rate <60 beats per minute in an adult, may result from various cardiac or non-cardiac causes but is not typically associated with a fever.
Choice B rationale
Fluid volume deficit (hypovolemia) typically stimulates the sympathetic nervous system and the baroreceptor reflex, leading to an increase in heart rate (tachycardia) in an attempt to maintain cardiac output and blood pressure. Severe bradycardia would impair cardiac output and perfusion, but it is not a typical finding or cause of a fluid volume deficit.
Choice C rationale
Lightheadedness, or dizziness, is a common symptom of decreased cerebral perfusion, which occurs when the heart rate is too slow (bradycardia) to maintain adequate cardiac output and blood pressure. Reduced cardiac output directly leads to less oxygenated blood reaching the brain, causing these signs of hypoperfusion.
Choice D rationale
Anxiety activates the sympathetic nervous system, causing the release of epinephrine and norepinephrine. These catecholamines act on beta-adrenergic receptors in the heart, leading to an increase in heart rate (tachycardia). Therefore, anxiety is generally associated with an elevated heart rate, not the decreased heart rate characteristic of bradycardia.
Correct Answer is B
Explanation
Choice A rationale
Bisacodyl (Dulcolax) is a stimulant laxative that acts by irritating the colon mucosa, increasing peristalsis, and promoting fluid accumulation in the colon to facilitate a bowel movement. Therefore, it is used to treat constipation, not diarrhea. Diarrhea management often involves antidiarrheal agents like loperamide or fluid replacement.
Choice B rationale
Bisacodyl is correctly prescribed for the management of constipation, which is characterized by infrequent bowel movements, difficulty passing stools, or hard stools. As a stimulant laxative, it works directly on the nerve plexuses in the bowel wall to enhance colonic motility, typically producing a bowel movement within 6 to 12 hours after oral administration.
Choice C rationale
Bisacodyl is used to relieve the symptom of constipation, and while abdominal discomfort can be a part of constipation, the medication is not a primary treatment for generalized abdominal pain of unknown etiology. Furthermore, excessive use or high doses of bisacodyl can sometimes cause or worsen abdominal cramping.
Choice D rationale
Fecal incontinence is the involuntary passage of stool, which can result from various conditions such as nerve damage or sphincter dysfunction. Bisacodyl, a laxative, would exacerbate fecal incontinence by promoting a bowel movement, making this an inappropriate and potentially harmful indication for its use.
