A client is scheduled for a bone scan to rule out osteosarcoma of the pelvic bones. Which client status would be most important for the nurse to verify before the client's scan?
Fast for at least 8 hours.
Completion of the bowel cleansing regimen.
Empty bladder.
No allergy to penicillins.
The Correct Answer is C
Choice A rationale
Fasting for at least 8 hours is usually required for certain diagnostic tests that involve anesthesia or contrast media, but it is not necessary for a bone scan. A bone scan typically involves the injection of a radioactive tracer and does not require fasting.
Choice B rationale
Completion of a bowel cleansing regimen is necessary for certain gastrointestinal procedures such as colonoscopy, but it is not relevant for a bone scan. A bone scan focuses on detecting bone abnormalities and does not involve the digestive system.
Choice C rationale
Emptying the bladder is important before a bone scan to ensure clear imaging of the pelvic bones. A full bladder can obscure the view and interfere with the accuracy of the scan. Ensuring the bladder is empty helps in obtaining better diagnostic images.
Choice D rationale
No allergy to penicillins is crucial information for procedures involving antibiotics, especially for patients with a history of allergic reactions. However, it is not pertinent to a bone scan, which uses a radioactive tracer rather than antibiotics.

Correct Answer is B
Explanation
Choice A rationale
The dura mater is the outermost, tough, and fibrous layer of the meninges that provides protection to the brain and spinal cord.
Choice B rationale
Meninges collectively refer to the three layers of protective membranes (dura mater, arachnoid mater, and pia mater) that cover the brain and spinal cord.
Choice C rationale
The pia mater is the delicate innermost layer of the meninges that closely envelopes the brain and spinal cord, providing support and nourishment.
Choice D rationale
The arachnoid mater is the middle layer of the meninges that has a web-like appearance and provides cushioning for the brain and spinal cord.
Correct Answer is B
Explanation
Choice A rationale
The temporal lobe is primarily responsible for processing auditory information and is involved in memory formation. It plays a crucial role in hearing, language comprehension, and storing visual memories. It is not primarily responsible for abstract thought.
Choice B rationale
The frontal lobe is the largest of the cerebral lobes and is primarily involved in higher cognitive functions such as abstract thought, decision-making, problem-solving, and planning. It also plays a significant role in controlling voluntary movements, speech production, and emotional regulation.
Choice C rationale
The parietal lobe is involved in processing sensory information such as touch, temperature, and pain. It plays a role in spatial orientation and perception, as well as integrating sensory input to form a coherent understanding of the environment. It is not the largest lobe nor the one controlling abstract thought.
Choice D rationale
The occipital lobe is primarily responsible for processing visual information. It interprets visual stimuli from the eyes and helps in recognizing objects, shapes, and colors. It is not involved in abstract thought or higher cognitive functions.
