A nurse is preparing a client for magnetic resonance imaging (MRI). Which of the following statements should the nurse include when reinforcing teaching?
"Unlike an x-ray, the MRI allows you to move around a bit."
"Your exposure to radiation will be minimal."
"You will not be able to talk to the technician during the procedure."
"You'll have to remove metal objects such as watches and body jewelry."
The Correct Answer is D
A. "Unlike an x-ray, the MRI allows you to move around a bit":
This statement is not accurate. During an MRI, it is important for the client to remain as still as possible to obtain clear images. Movement can result in blurred images.
B. "Your exposure to radiation will be minimal":
This statement is not applicable to MRI, as MRI does not use ionizing radiation. It uses a strong magnetic field and radio waves to generate images, making it different from x-rays in terms of radiation exposure.
C. "You will not be able to talk to the technician during the procedure":
While it is essential for the client to remain still during an MRI, communication with the technician is generally possible through an intercom system. The client may be given instructions and reassurance during the procedure.
D. "You'll have to remove metal objects such as watches and body jewelry":
This is the correct statement. Metal objects can interfere with the magnetic field used in MRI and can pose a safety risk. Therefore, clients are required to remove any metal objects before undergoing an MRI.

A. Concurrent treatment for GERD (gastroesophageal reflux disease) is not typically a contraindication for hormone replacement therapy. However, it's essential to assess the specific details of the client's medical history and medications to ensure safe use.
B. A history of breast cancer is a significant contraindication for hormone replacement therapy. Estrogen, a component of many HRT regimens, can stimulate the growth of certain types of breast cancer. Therefore, HRT is generally avoided in individuals with a history of breast cancer.

Correct Answer is A
Explanation
A. Disorientation in an older adult after taking lorazepam could indicate an adverse reaction or an excessive sedative effect. It's crucial to report this immediately as it may signify an overdose or an adverse reaction to the medication. Older adults are more sensitive to the sedative effects of benzodiazepines, and disorientation can indicate potential serious side effects.
B. Anorexia (loss of appetite) is a possible side effect of lorazepam but is not typically considered an urgent or immediate concern unless it leads to severe dehydration or other complications.
C. Increased anxiety could potentially occur due to paradoxical reactions to benzodiazepines; however, it's not typically considered an urgent or immediate concern unless it's severe or distressing to the client.
D. Blurred vision is a common side effect of lorazepam and other benzodiazepines. While it should be monitored and reported, it might not be considered an urgent concern unless it's significantly affecting the client's ability to function or is accompanied by other severe symptoms.
