Question 1 of 5
Which of the following statements best describes substance P?
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.
Question 2 of 5
Who is legally able to make decisions for the patient or resident during a patient care conference when the patient is not mentally able to make decisions on their own?
Correct Answer: C
Rationale: When a patient is unable to make decisions due to mental incapacity, the healthcare proxy, designated by the patient in advance, has the legal authority to make decisions on the patient's behalf. In this situation, the patient lacks the capacity to make decisions independently. The healthcare proxy's role is to represent the patient's wishes and best interests. The doctor's role in a patient care conference is to provide medical expertise, offer recommendations, and assist in the decision-making process, but the final decision-making authority lies with the healthcare proxy, not the doctor.
Question 3 of 5
You are taking care of 7 patients today. One of your residents wants water; another needs help walking to the bathroom; another just stated that they have chest pain; and another is crying because his daughter did not visit him today. Which patient care task is the lowest in terms of priority?
Correct Answer: D
Rationale: The lowest priority patient care task in this scenario is addressing the emotional need of the patient who is crying because his daughter did not visit him today. While emotional support is important, the other needs - providing water, assisting to the bathroom, and addressing chest pain - are physical needs that must take priority as they directly impact the patient's well-being and health. It is crucial to acknowledge and address emotional needs but in this situation, the physical needs of the patients should be addressed first.
Question 4 of 5
Match the abbreviation with the correct definition:
Correct Answer: C
Rationale: The abbreviation 'ac' stands for 'ante cibum,' which means 'before meals.' 'Bid' means twice a day. 'Tid' means three times a day, and 'pc' means after meals. When interpreting medical abbreviations, it is crucial to understand their precise meanings to ensure accurate communication and patient care.
Question 5 of 5
A nursing care plan states, 'Assist the patient to the bedside commode PRN.' When will this patient get this assistance to the commode?
Correct Answer: A
Rationale: The correct answer is 'Whenever needed.' The abbreviation 'PRN' stands for 'pro re nata,' which translates to 'as needed' or 'whenever necessary.' This means that the patient will receive assistance to the commode whenever they require it, based on their individual needs and condition.
Choices B, C, and D are incorrect because 'PRN' does not specify a specific time like bedtime, during the night, or during the day; instead, it indicates assistance based on the patient's needs.
