A client has sustained traumatic injuries that involve several bone fractures. A fracture of what type of bone may interfere with the protection of the client's vital organs?

Irregular bones.

Flat bones.

Long bones.

Short bones.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Irregular bones have complex shapes that do not fit into the other categories (long, short, or flat bones). They include bones such as the vertebrae and facial bones, which have specialized functions but are not primarily responsible for protecting vital organs.

Choice B rationale

Flat bones, such as the sternum, ribs, and skull bones, are designed to protect vital organs. They provide broad surfaces for muscle attachment and serve as protective barriers for organs like the brain, heart, and lungs.

Choice C rationale

Long bones, such as the femur and humerus, are primarily responsible for supporting the weight of the body and facilitating movement. While they contribute to the overall structure of the body, they are not specifically designed for organ protection.

Choice D rationale

Short bones, such as the carpals and tarsals, provide support and stability with limited movement. They are not primarily involved in the protection of vital organs.

Correct Answer is C

Explanation

Choice A rationale

Furuncles, also known as boils, are deep folliculitis caused by bacterial infection, not sebum blockage.

Choice B rationale

Carbuncles are clusters of furuncles connected under the skin and are also caused by bacterial infection, not sebum blockage.

Choice C rationale

Comedones are primary lesions of acne caused by the blockage of hair follicles by sebum and keratin. They can be open (blackheads) or closed (whiteheads).

Choice D rationale

Striae, also known as stretch marks, are caused by the tearing of the dermis due to rapid stretching of the skin and are not related to sebum blockage in hair follicles.

A. MRI. B. Lumbar puncture. C. Cerebral angiography. D. EEG.

Correct Answer is B

Explanation

Choice A rationale

MRI is a non-invasive imaging technique that uses magnetic fields and radio waves to create detailed images of the body's structures. The preparation for an MRI typically involves removing metal objects and sometimes fasting, but it is not similar to a myelogram.

Choice B rationale

A lumbar puncture, like a myelogram, involves inserting a needle into the spinal canal to collect cerebrospinal fluid or inject contrast dye. The preparation for both procedures includes obtaining consent, positioning the patient, and ensuring proper hydration. This similarity is why the nurse should explain that the preparation is akin to a lumbar puncture.

Choice C rationale

Cerebral angiography is an invasive procedure used to visualize blood vessels in the brain, requiring catheter insertion and contrast dye. The preparation is more complex, involving fasting and possible sedation, differing from the simpler preparation for a myelogram.

Choice D rationale

An EEG (electroencephalogram) measures electrical activity in the brain using electrodes placed on the scalp. The preparation is generally non-invasive and less intensive than that for a myelogram, typically involving clean hair and avoiding caffeine.
