A client is undergoing an abdominal computed tomography (CT) scan to evaluate suspected cholecystitis. The client expresses concern about potential radiation exposure. Which of the following responses should the nurse provide?

"The CT scan uses a magnetic field, so there is no radiation exposure."

"The amount of radiation used in a CT scan is very low and safe."

"There is no need to worry about radiation as the scan is done quickly."

"CT scans do not use radiation; they use sound waves for imaging."

Answer and Explanation

The Correct Answer is B

Choice A reason:

CT scans use X-rays, not magnetic fields, to create detailed cross-sectional images of the body. They involve radiation exposure.

Choice B reason:

This statement is correct. While CT scans use X-rays, the amount of radiation used in modern CT machines is relatively low and considered safe. The benefits of the diagnostic information obtained from the scan usually outweigh the risks associated with the small amount of radiation exposure.

Choice C reason:

The speed of the scan does not impact the radiation exposure. The amount of radiation used in a CT scan remains the same regardless of the scan duration.

Choice D reason:

CT scans use X-rays, not sound waves. Sound waves are used in ultrasound imaging, not in CT scans.

Correct Answer is B

Explanation

Choice A reason:

Avoiding all dairy products is not a preventive measure for H. pylori reinfection. Dairy consumption does not play a significant role in H. pylori colonization or infection.

Choice B reason:

This statement is correct. H. pylori is primarily transmitted through the oral-oral or fecal-oral route. Practicing strict hand hygiene, especially after using the restroom and before eating, can help reduce the risk of transmission and reinfection.

Choice C reason:

Including raw vegetables in the diet is not a specific preventive measure for H. pylori reinfection. A balanced diet that promotes overall gut health may be beneficial, but raw vegetables alone do not prevent H. pylori reinfection.

Choice D reason:

Taking over-the-counter antacids regularly is not a preventive strategy for H. pylori reinfection. Antacids do not target the bacterium and are not effective in eradicating H. pylori.

A. "It is best to take the PPI with your meals to enhance its effectiveness." B. "You should take the PPI on an empty stomach, preferably 30 minutes before a meal." C. "You can take the PPI at any time of the day, as long as it is taken consistently." D. "Taking the PPI before bedtime is most effective for managing nighttime acid reflux."

Correct Answer is B

Explanation

Choice A reason:

Taking the PPI with meals is not the most effective timing for acid suppression. PPIs work best when taken on an empty stomach.

Choice B reason:

This statement is correct. PPIs are most effective when taken on an empty stomach, about 30 minutes before a meal. This allows the medication to be absorbed and inhibit acid secretion in the stomach before food intake.

Choice C reason:

While consistency in medication timing is important, taking the PPI at any time of the day may not optimize its effectiveness.

Choice D reason:

Taking the PPI before bedtime may not provide the best acid suppression throughout the day. Taking it on an empty stomach before a meal is a more appropriate approach.
