Biological Basis of Behavior Questions
Question 1 of 5
The nurse would associate the fight-or-flight response with which neurotransmitter?
Correct Answer: D
Rationale: The correct answer is D: Norepinephrine. The fight-or-flight response is a physiological reaction that occurs in response to a perceived threat or stressor. Norepinephrine is the primary neurotransmitter involved in activating this response by increasing heart rate, blood pressure, and alertness. Acetylcholine (A) is involved in muscle contractions and parasympathetic nervous system functions. Dopamine (B) is associated with pleasure and reward pathways. Serotonin (C) is involved in mood regulation and sleep. Therefore, D is the correct answer as it directly relates to the fight-or-flight response.
Question 2 of 5
When under stress, a client routinely uses alcohol to excess. When the client's husband finds her drunk, the husband yells at the client about her chronic alcohol abuse. Which action alerts the nurse to the client's use of the defense mechanism of denial?
Correct Answer: D
Rationale: The correct answer is D. The client's statement "I don't drink too much!" demonstrates denial, a defense mechanism where the individual refuses to acknowledge reality. This response indicates the client's inability to accept her excessive alcohol use. A: Hiding liquor bottles in a closet suggests secrecy, not denial. B: Yelling at her son for slouching is displacement, not denial. C: Burning dinner on purpose is passive-aggressive behavior, not denial. In summary, the client's statement denying her alcohol abuse directly reflects the defense mechanism of denial, making it the correct choice in this scenario.
Question 3 of 5
Troy is a one day post open reduction and internal fixation (ORIF) of the left hip and is in pain. Which of the following observation would prompt you to call the doctor?
Correct Answer: B
Rationale: The correct answer is B because a cold left foot with an absent pedal pulse could indicate compromised blood flow, which is concerning for potential vascular compromise or development of a blood clot post ORIF. This observation warrants immediate medical attention to prevent serious complications such as ischemia or thrombosis. Choices A, C, and D are not as urgent as they do not directly indicate potential vascular compromise or circulatory issues. A partially soiled dressing (Choice A) may require changing but does not indicate immediate danger. Limited functional anatomic position (Choice C) may be addressed with repositioning but does not signal an emergency. Normal blood pressure and pulse rate (Choice D) are within acceptable ranges and do not raise immediate concerns.
Question 4 of 5
Records Management and Archives Office of the DOH is responsible for implementing its policies on record disposal. You know that your institution is covered by this policy if:
Correct Answer: C
Rationale: The correct answer is C: It obtained permit to operate from DOH. This is because the Records Management and Archives Office of the DOH is responsible for implementing record disposal policies for institutions that are under the jurisdiction of the Department of Health. Obtaining a permit to operate from the DOH indicates that the institution is recognized and regulated by the department, making it subject to the record disposal policies. Choices A, B, and D are incorrect as they do not directly relate to the institution being covered by the record disposal policy of the DOH.
Question 5 of 5
It is also the nurse's function to determine when infection is developing in the surgical incision. The perioperative nurse should observe for what signs of impending infection?
Correct Answer: A
Rationale: The correct answer is A: Localized heat and redness. This is because heat and redness are classic signs of inflammation, which can indicate an infection developing in a surgical incision. The increased blood flow to the area causes heat, and the dilation of blood vessels causes redness. Serosanguinous exudates (choice B) and separation of the incision (choice C) are more indicative of normal wound healing or other complications rather than infection. Blood clots and scar tissue (choice D) are not typical signs of impending infection.
