Correct Answer is A

Explanation

A. Pass a small amount of urine into the toilet and then collect the specimen. This technique ensures that bacteria or debris from the urethra are flushed out before the sample is collected, providing a clean-catch specimen for analysis.

B. Void until the bladder is almost empty and then collect the end portion: This would result in a less accurate sample, as bacteria or debris might accumulate.

C. Let a few drops of urine dribble into the specimen cup: This does not provide enough urine for analysis.

D. Begin voiding into the specimen cup: This may contaminate the sample with bacteria from the external genitalia.

A. Send the medications home with a family member. B. Notify the physician about the medications the patient has been taking C. Administer the medications with the ordered medications. D. Seal the medications in an envelope and lock it in the medicine cart.

Correct Answer is B

Explanation

A. Send the medications home with a family member: This may result in the patient not having access to essential medications.

B. Notify the physician about the medications the patient has been taking. The physician must be informed to evaluate the medications and determine whether they should be added to the current orders. This ensures patient safety and prevents potential adverse drug interactions.

C. Administer the medications with the ordered medications: Unsafe without physician approval, as it may lead to drug interactions.

D. Seal the medications in an envelope and lock it in the medicine cart: This delays action and does not address the patient’s potential need for the medications.
