Exam 3 Multiple Choice

Multiple Choice Questions - Study Notes

• Subcutaneous Emphysema: Expressed as an antemortem condition caused by surgery or trauma, not a postmortem intravascular or microbial invasion.

• Extravascular Discoloration: Petechiae, purpura, and ecchymosis are examples. Hypostasis is not an extravascular discoloration.

• Jaundice Cause: Bilirubin is the bile pigment responsible for jaundice.

• Nephritis Skin Color Change: Nephritis can cause the skin to turn a bronze-like color, not reddish-purplish, sallow-yellow or yellow-green.

• Formaldehyde Grey: Caused by using a too strong arterial solution or a too rapid rate of flow, not a mixture of blood with the arterial solution or an inappropriate arterial solution.

• Ante-mortem Dehydration: TB can cause dehydration. Blood thickens and clots during dehydration. Tissue can have an alkaline value. Skin darkening may also occur.

• Dehydration (General): Rapid injection and continuous drainage can cause dehydration. Surface dehydration is critical. Intermittent drainage helps prevent dehydration. A hypertonic solution maintains moisture balance.

• Aneurysm Definition: An abnormal dilation of a blood vessel, or a thickening and calcification of an artery wall is an aneurysm. Heavily congested blood, or ruptures, are not.

• Carbon Monoxide Poisoning Effects: Carbon monoxide poisoning may cause the skin to turn cherry red, not blue-black, sickly white or sallow yellowish.

• Infant Definition: An infant is any baby weighing 2,500 grams or less at birth.

• Body Water at Birth: Approximately 70% of a newborn baby's total body weight is comprised of water.

• Short-term Refrigeration Advantages: Short-term refrigeration slows down the rigor mortis cycle, potentially preventing tissue gas formation or skin slip and edema.

• Diabetes Mellitus Definition: A chronic metabolic disorder. Not acute.

• Bilirubin Conversion: Bilirubin converts to biliverdin after embalming.

• Humectants and Decomposition: Humectants are not recommended for decomposed cases.

• Tissue Gas Bacilli: Transmission of tissue gas bacilli from one body part to another via contaminated instruments is possible. All cases of decomposition do not involve tissue gas. Decomposition is a post-mortem chemical change.

Test your knowledge on key pathology concepts including subcutaneous emphysema, extravascular discoloration, and jaundice. Understand the nuances of various conditions and their effects on the body. This quiz is designed for students studying pathology or related fields.
