The nurse instructing in the collection of a midstream urine catch would tell the patient to first cleanse the external genitalia and then to:

Pass a small amount of urine into the toilet and then collect the specimen.

Void until the bladder is almost empty and then collect the end portion of the voiding in the cup.

Let a few drops of urine dribble into the specimen cup.

Begin voiding into the specimen cup.

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is D

Explanation

A. Respiratory allergies: While respiratory allergies may be relevant to a patient's overall health, they are generally not a significant concern for MRI preparations. However, any specific conditions such as asthma should be noted for patient safety.

B. Dizziness: Dizziness is not specifically related to the MRI procedure itself but could be important in assessing the patient's overall stability. If the patient experiences dizziness, the nurse may need to monitor for safety concerns during the MRI.

C. Fear of the dark: While some patients may experience anxiety in dark or enclosed spaces, fear of the dark is not typically a major consideration for MRI procedures.

D. Claustrophobia: Claustrophobia is a key consideration when preparing a patient for an MRI. MRI machines are often enclosed, and patients may experience anxiety or panic due to the confined space. It's essential to assess for this condition to provide sedation.

A. "You will not be able to talk to the technician during the procedure." B. "Your exposure to radiation will be minimal." C. "Unlike an x-ray, the MRI allows you to move around a bit." D. "You'll have to remove metal objects such as watches and body jewelry."

Correct Answer is D

Explanation

A. "You will not be able to talk to the technician during the procedure.": Most MRIs allow communication via intercom.

B. "Your exposure to radiation will be minimal.": MRI does not use ionizing radiation, unlike CT scans or X-rays.

C. "Unlike an x-ray, the MRI allows you to move around a bit.": Movement during MRI imaging can result in blurred images.

D. "You'll have to remove metal objects such as watches and body jewelry." MRI uses strong magnetic fields, so all metal objects must be removed to avoid injury or interference with imaging.
