A nurse is preparing a preoperative patient for a sigmoid colostomy. What information should the nurse include in the discussion?
The stoma will be located in the lower left abdomen.
The stoma may appear purple.
The colostomy will not produce formed stool.
The end of the stoma may be painful after the procedure.
The Correct Answer is A
Choice A rationale
The stoma for a sigmoid colostomy is typically located in the lower left abdomen. This is because the sigmoid colon is a part of the large intestine that is located in the lower left quadrant of the abdomen.
Choice B rationale
A stoma should appear pink or red and moist. A purple stoma could indicate a lack of blood supply, which is a medical emergency.
Choice C rationale
A sigmoid colostomy will produce formed stool because the sigmoid colon is the last part of the colon, where water is absorbed and stool is formed.
Choice D rationale
The end of the stoma (the part that sticks out from the abdomen) should not be painful after the procedure. If a patient experiences pain, it could indicate a complication such as a blockage or infection.

Correct Answer is C
Explanation
Choice A rationale
Vibration of the eardrum is not directly transmitted to the eighth cranial nerve, bypassing the inner ear structures. The vibrations from the eardrum are first transmitted through the ossicles (tiny bones in the middle ear) to the cochlea in the inner ear.
Choice B rationale
Sound waves enter the ear canal, but they are not directly converted to electrical impulses. The sound waves cause the eardrum to vibrate, and these vibrations are transmitted through the ossicles to the cochlea, where they are converted into electrical signals that are sent to the brain via the eighth cranial nerve.
Choice C rationale
Vibration of the eardrum transmits through the bony ossicles to the perilymph in the inner ear, stimulating the eighth cranial nerve. This is the correct description of the process of hearing.
Choice D rationale
Sound is not transmitted directly from the eardrum to the brain. The sound-induced vibrations of the eardrum are transmitted through the ossicles to the cochlea, where they are converted into electrical signals that are sent to the brain via the eighth cranial nerve.
Correct Answer is ["A","C"]
Explanation
Choice A rationale
A specific gravity of 1.036 is higher than the normal range of 1.005 to 1.030345. This could indicate dehydration or other conditions that cause the urine to be more concentrated. This finding should prompt the nurse to follow up.
Choice B rationale
A pH of 6.4 is within the normal range for urine, which is typically between 4.6 and 8.03. Therefore, this finding would not necessarily require follow-up.
Choice C rationale
The presence of proteinuria (protein in the urine) is abnormal and could indicate kidney disease or other serious health conditions. This finding should prompt the nurse to follow up.
Choice D rationale
The presence of hematuria (blood in the urine) can be a sign of several conditions, including urinary tract infections, kidney stones, or bladder infections. However, without more information, it’s not clear whether this finding alone should prompt the nurse to follow up.
