NCLEX EXAMINATION CHAPTER 27: GENERAL ANESTHETICS QUESTIONS AND ANSWERS WITH SOLUTIONS 2024 The nurse evaluates the effectiveness of an analgesic by observing the patient for decreased sensation to what? A. Pressure B. Spasm C. Touch D. Pain - ANSWER D. Pain The term analgesia refers to loss of sensibility to pain, whereas anesthesia refers to loss of pain, touch, temperature, and taste. During general anesthesia, all sensation is lost, and consciousness is also lost. The nurse understands that ________ is/are used for induction of anesthesia in balanced anesthesia. A. propofol and short -acting barbiturate B. short -acting barbiturate and neuromuscular agents C. nitrous oxide D. opioids - ANSWER A. propofol and short -acting barbiturate Balanced anesthesia is a technique that employs more than one drug to ensure that induction is smooth and rapid and that analgesia and muscle relaxation are adequate. Agents used most commonly include propofol and short -acting barbiturates for induction of anesthesia, neuromuscular blocking agents for muscle relaxation, and opioids and nitrous oxide for analgesia. The nurse recognizes that these drugs, used in inhalation anesthesia, work by enhancing activation of receptors for gamma aminobutyric acid (GABA). (Select all that apply.) A. Enflurane B. Isoflurane C. Desflurane D. Nitrous oxide - ANSWER A. Enflurane B. Isoflurane C. Desflurane Inhalation anesthetics work by enhancing transmission of inhibitory synapses and by depressing transmission at excitatory synapses. Except for nitrous oxide, all of the agents used today enhance activation of receptors for GABA, the principal inhibitory tr ansmitter in the central nervous system. As a result, these drugs promote generalized inhibition of the central nervous system. The nurse understands that which drug cannot be used alone for surgical anesthesia? A. Enflurane B. Sevoflurane C. Isoflurane D. Nitrous oxide - ANSWER D. Nitrous oxide Nitrous oxide has a high minimum alveolar concentration (MAC). The MAC is the minimum concentration of drug in the alveolar air that will produce immobility in 50% of patients exposed to painful stimuli. A low MAC indicates high anesthetic potency and also indicates that the inspired air needs to contain only a low concentration of the anesthetic to produce surgical anesthesia. Nitrous oxide has a very high MAC, so high that surgical anesthesia cannot be achieved with this drug alone. The nurse associates the rapid rise of anesthetic levels with which organ(s)? (Select all that apply.) A. Fat B. Skin C. Brain D. Heart E. KidneyThe benefits of buying summaries with Stuvia:
