As part of an annual physical examination, a nurse is preparing a client to undergo a chest x-ray. Which of the following instructions should the nurse give the client prior to the procedure?

Remove all metal necklaces.

Take several shallow breaths during the procedure.

Do not eat or drink anything the morning of the test.

Expect minor discomfort after the procedure.

Answer and Explanation

The Correct Answer is A

A reason:

Removing all metal necklaces is correct because metal objects can interfere with the x-ray imaging. Metal can cause artifacts on the x-ray, making it difficult to interpret the results accurately. Therefore, clients are advised to remove any metal jewelry or accessories before the procedure.

B reason:

Taking several shallow breaths during the procedure is not correct. Clients are usually instructed to take a deep breath and hold it for a few seconds while the x-ray is being taken. This helps to get a clear image of the chest.

C reason:

Not eating or drinking anything the morning of the test is not necessary for a chest x-ray. This instruction is more relevant for certain other tests, such as blood tests or imaging studies requiring contrast. For a chest x-ray, there are no such restrictions.

D reason:

Expecting minor discomfort after the procedure is incorrect. A chest x-ray is a non-invasive and painless procedure. Patients typically do not experience any discomfort afterward.

Correct Answer is A

Explanation

A reason:

A pH reading of 1-4 is expected for gastric contents. This acidic range indicates that the NG tube is correctly placed in the stomach, where gastric secretions have a low pH due to hydrochloric acid.

B reason:

A pH reading of 5-7 is more indicative of respiratory secretions or the contents of the small intestine, not the stomach. This range suggests that the NG tube may be incorrectly placed.

C reason:

A pH reading of 8-10 is too alkaline for gastric contents and indicates incorrect tube placement. This range could suggest the presence of intestinal or respiratory secretions, not gastric.

D reason:

A pH reading of 11-14 is highly alkaline and unlikely to be encountered in clinical practice for this purpose. Such a high pH is not compatible with gastric contents and suggests a significant error or contamination in the test.

A. Hold the hands higher than the elbows. B. Rub hands and arms to dry. C. Adjust the water temperature to feel hot. D. Apply 4 to 5 ml of liquid soap to the hands.

Correct Answer is D

Explanation

A reason:

Holding the hands higher than the elbows is incorrect. Hands should be held lower than the elbows during washing to allow water to flow from the cleanest to the dirtiest area and prevent recontamination.

B reason:

Rubbing hands and arms to dry is incorrect. Hands should be dried using a clean towel or air dryer. Rubbing can reintroduce bacteria and is not recommended.

C reason:

Adjusting the water temperature to feel hot is incorrect. Water should be warm, not hot, to avoid skin irritation and ensure effective hand hygiene.

D reason:

Applying 4 to 5 ml of liquid soap to the hands is correct. Using an adequate amount of soap ensures thorough cleaning and removal of germs and contaminants during hand washing.
