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 A
Explanation
Choice A rationale
Administering systemic antibiotics is essential to treat the underlying bacterial infection causing severe impetigo. This intervention helps reduce infection spread and promotes healing.
Choice B rationale
Placing mitts on the client's hands may prevent scratching, which can worsen impetigo, but it is not the primary treatment for the infection itself. Antibiotic therapy is more crucial.
Choice C rationale
Continuing antibiotics for 21 days is not a standard duration for impetigo treatment. The treatment duration typically ranges from 7 to 10 days, depending on the severity and response to treatment.
Choice D rationale
Topical antibiotics are used for mild cases of impetigo. For severe impetigo, systemic antibiotics are more appropriate and effective in managing the infection.
Correct Answer is D
Explanation
Choice A rationale
Cerebrospinal fluid (CSF) does not produce cerebral neurotransmitters. Neurotransmitters are produced by neurons in the brain and nervous system.
Choice B rationale
CSF provides a protective barrier to some extent, but its primary function is not to act as a barrier to bacteria. The blood-brain barrier primarily serves this function.
Choice C rationale
CSF helps maintain a stable environment in the central nervous system but is not primarily an insulator for maintaining constant temperature. Its thermal properties are secondary.
Choice D rationale
The primary function of CSF is to cushion and protect the brain and spinal cord from mechanical injury. It also helps maintain the brain's buoyancy and provides a stable environment for the central nervous system.
