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.

Answer and Explanation

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 D

Explanation

Choice A rationale

Roth's spots are retinal hemorrhages with pale centers, indicative of certain systemic conditions, but do not relate to pupil response or parasympathetic effects.

Choice B rationale

One pupil being dilated while the other is normal could indicate a variety of issues, but not specifically a parasympathetic effect. This condition is known as anisocoria.

Choice C rationale

Dilated pupils, or mydriasis, are usually the result of sympathetic stimulation, not a parasympathetic effect, which involves constriction of the pupils.

Choice D rationale

Constricted pupils, or miosis, are a parasympathetic effect typically resulting from increased activity of the parasympathetic nervous system, which reduces pupil size.

A. Occipital. B. Frontal. C. Temporal. D. Parietal.

Correct Answer is D

Explanation

Choice A rationale

The occipital lobe is responsible for processing visual information and does not play a significant role in spatial relationships.

Choice B rationale

The frontal lobe is involved in higher cognitive functions, decision-making, and voluntary movements, but it is not primarily responsible for spatial relationships.

Choice C rationale

The temporal lobe is involved in auditory processing, language comprehension, and memory formation. It is not primarily responsible for spatial relationships.

Choice D rationale

The parietal lobe is responsible for processing sensory information and plays a crucial role in spatial relationships, helping to understand and navigate the environment.
