E. Bleeding tendencies: While bleeding tendencies are a concern for invasive procedures, they are not a contraindication for MRI.

Correct Answer is A

Explanation

A. Listen to the patient, answer questions, and offer to have the supervisor or physician speak with the patient. Understanding the patient’s concerns and providing information may help address their reasons for leaving and promote informed decision-making. Involving the supervisor or physician allows for further discussion.

B. Call both the supervisor and a family member to try to get the patient to reconsider: Family involvement should only occur with the patient’s consent.

C. Obtain a written explanation of the reasons from the patient: This can be done after addressing the patient’s concerns.

D. Advise the patient that insurance may not pay for this hospitalization: This may seem coercive and is not an immediate priority.

A. Void a small amount of urine after external genitalia are cleansed. B. Empty the bladder into the toilet and begin timing the collection. C. Keep the container on ice if instructed to do so. D. Keep the container refrigerated as needed. E. Save only the first voiding in the morning.

Correct Answer is ["B","C","D"]

Explanation

A. Void a small amount of urine after external genitalia are cleansed: This applies to midstream clean-catch specimens, not 24-hour urine collection.

B. Empty the bladder into the toilet and begin timing the collection: The first void is discarded, and timing starts afterward.

C. Keep the container on ice if instructed to do so: Some tests require the specimen to remain cool to preserve its integrity.

D. Keep the container refrigerated as needed: Refrigeration may be required depending on the specific test to prevent sample degradation.

E. Save only the first voiding in the morning: The first void is discarded to ensure accurate timing and complete collection for the 24-hour period.
