Practice quiz questions from Ch 2-10 in Pathophysiology questions taken from Porth, C. M. Essentials of Pathophysiology: Concepts of Altered Health States, A biochemical event, such as nucleotide change, deletion, or insertion, that produces a new allele is called which of the following? - correct answersMutation A mutation is a biochemical event, such as nucleotide change, deletion, or insertion, that produces a new allele. -Polymorphism refers to genes that have more than one normal allele at the same locus. -Although gene expression usually follows a dominant or recessive pattern, it is possible for both alleles of a gene pair to be fully expressed in the heterozygote. This is codominance. -When a person inherits a dominant mutant gene, but fails to express it, it is called reduced penetrance. A client asks the health care provider if any technology exists to limit faulty gene activity from producing unwanted disease proteins. The best response would be: - correct answersDNA ? A client asks why his temperature is always below 98.6°F. The nurse responds: - correct answersNormal core temperature varies between individuals within the range of 97.0°F to 99.5°F. Explanation: Core temperature is normally maintained within a range of 36.0°C to 37.5°C (97.0°F to 99.5°F). A core temperature greater than 41°C (105.8°F) or less than 34°C (93.2°F) usually indicates that the body's thermoregulatory ability is impaired. Body heat is generated in the tissues of the body, transferred to the skin surface by the blood, and then released into the environment surrounding the body. The thermoregulatory center regulates the temperature of the deep body tissues, or "core" of the body, rather than the surface temperature. Internal core temperatures reach their highest point in late afternoon and evening and their lowest point in the early morning
