Correct Answer is A
Explanation
A. Offer the patient their elbow for guidance: Offering the elbow is a common and safe method of guiding patients with visual impairments, including presbyopia, because it allows the patient to follow the assistant's movements more easily.
B. Take the patient's hand. Taking the patient's hand might make the patient feel less secure and can lead to an imbalance. It is less effective than offering the elbow.
C. Lead the patient by their arm: Leading the patient by their arm can be uncomfortable and does not provide the same level of control as offering the elbow.
D. Guide the patient by holding their waist: Holding the waist is inappropriate as it invades personal space and might make the patient uncomfortable.
Correct Answer is B
Explanation
A. "Clean the perineal area from back to front.": For females, cleaning should be done from front to back to avoid contamination from fecal matter. For males, cleaning should be done around the urethral opening.
B. "Void a small amount into the toilet before voiding into the cup.": This helps to flush out any contaminants from the urethra, ensuring that the urine collected in the cup is as clean as possible.
C. "Urinate directly into the container with preservative.": Urinating directly into a container with preservative can contaminate the sample and is not recommended for a clean catch specimen.
D. "Collect all urine from start to finish.": The clean catch method specifically involves discarding the initial stream of urine and collecting the midstream to avoid contaminants.
