Page: 5 Heading: Cell Structure and Function>Endoplasmic Reticulum>Ribosomes Integrated Processes: Nursing Process Client Need: Physiological Integrity: Physiological Adaptation Cognitive Level: Application [Applying] Concept: Cellular Regulation Difficulty: Difficult DAVIS TEST BANK Feedback 1 This is correct. Ribosomes are known as the protein factories of the cell. Different types of cells produce different types of proteins. For example, ribosomes in pancreatic beta islet cells synthesize the proteins that make up insulin. The inability results in type 1 diabetes mellitus, a condition where the body is unable to produce insulin. 2 This is incorrect. Once ribosomes complete protein synthesis, the proteins are transported via the endoplasmic reticulum to the Golgi apparatus to be processed, packaged, and secreted. Impairment of this process does not result in type 1 diabetes mellitus. 3 This is incorrect. Microtubules are hollow filaments composed of protein subunits called tubulin . They have a dynamic structure, meaning that they are constantly being formed, broken down, and reformed. Stagnation of the process does not occur. 4 This is incorrect. The endoplasmic reticulum is a network of tubules that act as a transport system within the cell and help in the transport of proteins. Impairment of this process does not result in type 1 diabetes mellitus. PTS: 1 CON: Cellular Regulation 13.

Page: 6 Heading: Cell Structure andNFUuRncStiIonN>GDTNBA.RCeOpMlication Integrated Processes: Nursing Process Client Need: Physiological Integrity: Physiological Adaptation Cognitive Level: Analysis [Analyzing] Concept: Cellular Regulation Difficulty: Difficult Feedback 1 This is incorrect. Transfer RNA (tRNA) plays an important role in the assembly of proteins, but would not be examined as a source of severe deformities in a newborn. 2 This is incorrect. Proteins manufactured by ribosomes are destined to become parts of the cell, enzymes, or exported protein secretions. Different types of cells manufacture different proteins. However, ribosomal RNA is not examined for a cause of severe deformities in a newborn. 3 This is correct. In the event of severe physical deformities, the double helix of DNA will be examined for identifiable defects. The findings will identify the cause. The DNA of the parents will also be examined to aid in the identification of the condition being genetically transferred. 4 This is incorrect. It is theorized that in aging and in disorders such as diabetes, cancer, and heart failure, mitochondrial DNA undergoes mutations. Diseases that target mitochondria specifically may be caused by injury of mitochondria occurring in the cells of different organs. Mitochondrial disease causes a wide DAVIS TEST BANK array of problems, including energy depletion and severe muscle weakness, but not severe deformities. PTS: 1 CON: Cellular Regulation 14.
