1. Which of the following statements best describes substance P?
- A. Substance P decreases a client's sensitivity to pain
- B. Substance P levels are drawn before administration of narcotic analgesics
- C. Substance P is found in the brain and is responsible for pain control and management of depression
- D. Substance P is found in the dorsal horn of the spinal column
Correct answer: D
Rationale: Substance P is a neurotransmitter found in the brain and the dorsal horn of the spinal column, not just in the brain. It is associated with pain transmission and modulation. Substance P is known to cause inflammation, edema, and pain. While it plays a role in pain perception, it does not decrease a client's sensitivity to pain (Choice A), nor are its levels typically drawn before administering narcotic analgesics (Choice B). Although substance P is involved in pain control, it is not responsible for managing depression (Choice C). Therefore, the correct statement is that substance P is found in the dorsal horn of the spinal column.
2. While measuring a patient's blood pressure, which factor influences a patient's blood pressure?
- A. Pulse rate
- B. Pulse pressure
- C. Vascular output
- D. Peripheral vascular resistance
Correct answer: D
Rationale: When measuring a patient's blood pressure, it is important to consider various factors that influence blood pressure. Peripheral vascular resistance plays a crucial role in regulating blood pressure. The level of blood pressure is affected by factors such as cardiac output, peripheral vascular resistance, volume of circulating blood, viscosity, and elasticity of the vessel walls. Pulse rate (Choice A) refers to the number of heartbeats per minute and is not a primary factor influencing blood pressure. Pulse pressure (Choice B) is the difference between systolic and diastolic blood pressure and does not directly impact blood pressure regulation. Vascular output (Choice C) is not a recognized term in blood pressure regulation and is not a primary factor affecting blood pressure.
3. Your patient has finished a 12-ounce can of iced tea and 8 ounces of fresh orange juice. What will you record on the Intake and Output form for this patient's intake?
- A. 20 cc
- B. 20 cm
- C. 600 cc
- D. 600 cm
Correct answer: C
Rationale: You will record 600 cc of fluid intake. There are 600 cc in 20 ounces (12 ounces of iced tea + 8 ounces of orange juice) of fluid intake. Choice A and B are incorrect as they do not reflect the correct conversion of fluid intake from ounces to cubic centimeters. Choice D is incorrect as it provides the measurement in cubic centimeters but does not account for the total fluid intake accurately.
4. During an initial assessment interview, which statement made by a patient should serve as the priority focus for the plan of care?
- A. "I can always trust my family."?
- B. "It seems like I always have bad luck."?
- C. "You never know who will turn against you."?
- D. "I hear evil voices that tell me to do bad things."?
Correct answer: D
Rationale: The statement about hearing evil voices indicates that the patient is experiencing auditory hallucinations, which is a significant symptom that requires immediate attention and intervention. This symptom can be associated with serious mental health conditions like psychosis. Choices A, B, and C are more general statements that do not provide specific information about the patient's mental health status or symptoms, making them less urgent and not as critical for the plan of care compared to the presence of auditory hallucinations.
5. A client is undergoing range of motion exercises, and the nurse moves the leg in a pattern of circumduction. Which movement is the nurse performing?
- A. Bending the leg at the knee
- B. Turning the foot inward and outward
- C. Moving the leg in a circle
- D. Moving the leg forward and up
Correct answer: C
Rationale: Circumduction involves moving a limb in a circular pattern. In this scenario, the nurse is performing circumduction by moving the leg in a circular motion, engaging the muscles of the gluteus maximus and gluteus medius. Choice A, 'Bending the leg at the knee,' is incorrect as it describes flexion and extension movements. Choice B, 'Turning the foot inward and outward,' refers to inversion and eversion movements of the foot, not circumduction. Choice D, 'Moving the leg forward and up,' describes flexion and abduction movements, not circumduction.
