Practice quiz questions from Ch 2-10 in Pathophysiology questions taken from Porth, C. M. Essentials of Pathophysiology: Concepts of Altered Health States, 4th ed., Philadelphia: Wolters Kluwer Health/Lippincott Williams & Wilkins, 2024, Ch. 2-10 UPDATED LATEST VERSION Fever and hyperthermia describe conditions in which body temperature is higher than the normal range. When does hyperthermia occur? - ANS When the body's set point is unchanged, but the temperature goes up A client has developed heart failure. The doctor reviews the client's chest x-ray and notes that the heart has enlarged. The changes in the size and shape of the heart are the result of: - ANS Hypertrophy Explanation: Cells adapt to changes in their environment and in their work demands by changing their size, number, and characteristics. An increase in work results in cells undergoing hypertrophy and increasing in size. Hyperplasia is an increase in the number of cells in an organ or tissue. A decrease in work demands or adverse environmental conditions results in cells atrophy, or reducing in size. Hypoplasia is underdevelopment or incomplete development of a tissue or an organ When explaining to a group of parents of school-aged children the importance of protein intake, the nurse emphasizes which food choices that contain all essential amino acids in adequate amounts per serving? Select all that apply. - ANS Eggs Which of the following conditions is characterized by a deficiency of the liver enzyme phenylalanine hydroxylase? - ANS Phenylketonuria 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: - ANS DNA ? A client asks why his temperature is always below 98.6°F. The nurse responds: - ANS Normal 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 hours A biochemical event, such as nucleotide change, deletion, or insertion, that produces a new allele is called which of the following? - ANS Mutation
