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. What is a common error when taking a pulse?
- A. Placing the index finger on the radial artery located on the thumb side of a patient's wrist.
- B. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure.
- C. Counting the pulse for 15 seconds and multiplying the number by four.
- D. None of the above will cause errors.
Correct answer: C
Rationale: The correct answer is counting the pulse for 15 seconds and multiplying the number by four. To accurately assess a patient's heart rate or pulse, it is crucial to count the pulse for a full minute. Counting for only 15 seconds and then multiplying by four may result in an inaccurate heart rate calculation. This approach could miss arrhythmias or intermittent pulsations that could be vital indicators of the patient's condition. Placing the index finger on the radial artery, which is located on the thumb side of the patient's wrist, is the correct technique for taking a pulse. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure is a valid observation and not an error in itself. Therefore, the most common error in this scenario is incorrectly calculating the pulse rate by multiplying a 15-second count by four.
3. What is the primary route of transmission of MRSA?
- A. Shared needles
- B. Hands of healthcare workers
- C. Items in the healthcare environment
- D. Blood transfusions
Correct answer: B
Rationale: The correct answer is 'Hands of healthcare workers.' MRSA is primarily transmitted via the unwashed hands of healthcare workers who can carry the Staphylococcus aureus bacterium from one patient to another. Shared needles, items in the healthcare environment, and blood transfusions are not the main routes of transmission for MRSA. Shared needles can transmit bloodborne pathogens, items in the healthcare environment can harbor bacteria but are not the primary mode for MRSA, and blood transfusions are not a common route for MRSA transmission.
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. When turning an immobile bedridden client without assistance, which action by the nurse best ensures client safety?
- A. Securely grasp the client's arm and leg.
- B. Put bed rails up on the side of bed opposite from the nurse.
- C. Correctly position and use a turn sheet.
- D. Lower the head of the client's bed slowly
Correct answer: B
Rationale: When turning an immobile bedridden client without assistance, the best action to ensure client safety is to put bed rails up on the side of the bed opposite from the nurse. This is important because the nurse can only stand on one side of the bed, so having bed rails on the opposite side prevents the client from falling out of bed. Option A, which suggests securely grasping the client's arm and leg, can potentially cause client injury to the skin or joints. Options C and D, correctly positioning and using a turn sheet, and lowering the head of the client's bed slowly, respectively, are useful techniques during client turning but are of lower priority in terms of safety compared to the use of bed rails.
