Learning Objectives By the end of this section, you will be able to: The preoperative nursing care plan includes interventions aimed at preparing the patient both physically and psychologically for the procedure while prioritizing patient safety. The nurse must be…
Learning Objectives By the end of this section, you will be able to: Preoperative nurses have several responsibilities and priorities. They are responsible for assessing not only the physical state of a patient but also the psychological and social states.…
Learning Objectives By the end of this section, you will be able to: The first of the three phases included in perioperative nursing is the preoperative phase. The preoperative phase starts when the decision is made to proceed with a surgery or…
Figure 25.1 Surgical handoff, a crucial aspect in perioperative nursing, is generally performed with the patient, preoperative nurse, intraoperative nurse, and an anesthesia provider. This process ensures patient safety by verifying name, date of birth, surgery being performed and site, allergies, and…
Nuclear Structure and Stability An atomic nucleus consists of protons and neutrons, collectively called nucleons. Although protons repel each other, the nucleus is held tightly together by a short-range, but very strong, force called the strong nuclear force. A nucleus…
Learning Objectives By the end of this section, you will be able to: The increased use of radioisotopes has led to increased concerns over the effects of these materials on biological systems (such as humans). All radioactive nuclides emit high-energy…
Learning Objectives By the end of this section, you will be able to: Radioactive isotopes have the same chemical properties as stable isotopes of the same element, but they emit radiation, which can be detected. If we replace one (or…
Learning Objectives By the end of this section, you will be able to: After the discovery of radioactivity, the field of nuclear chemistry was created and developed rapidly during the early twentieth century. A slew of new discoveries in the…
Learning Objectives By the end of this section, you will be able to: Following the somewhat serendipitous discovery of radioactivity by Becquerel, many prominent scientists began to investigate this new, intriguing phenomenon. Among them were Marie Curie (the first woman…
Learning Objectives By the end of this section, you will be able to: Changes of nuclei that result in changes in their atomic numbers, mass numbers, or energy states are nuclear reactions. To describe a nuclear reaction, we use an equation…
