1. 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.

2. A patient's Foley catheter has been discontinued. You will dispose of this patient equipment by doing which of the following?

A. Wearing gloves and then placing this equipment in the regular trash can after it is placed in a paper bag.
B. Simply placing this equipment in the regular trash can after it is placed in a paper bag.
C. Wearing gloves and then placing this equipment into a special 'hazardous waste' container.
D. Simply placing this equipment in the 'hazardous waste' container after it is placed in a paper bag.

Correct answer: C

Rationale: When disposing of used patient equipment, such as a Foley catheter, that has come in contact with bodily fluids, it is considered hazardous waste. The correct procedure involves wearing gloves and placing the Foley bag and tubing into a special 'hazardous waste' container. This container is marked as 'Hazardous' and is typically red to indicate the potential danger of its contents. Placing the equipment in a regular trash can, even if placed in a paper bag, is not appropriate as it does not meet the standards for disposing of hazardous waste. Therefore, options A and B are incorrect. Similarly, simply placing the equipment in a 'hazardous waste' container after it is placed in a paper bag is also incorrect as direct disposal into the designated container while wearing gloves is the proper protocol, making option D incorrect.

3. What does the term 'Afferent Nerve' mean?

A. Carrying an impulse to the brain
B. Carrying an impulse away from the brain
C. Carrying impulses to the motor neurons of the appendicular muscles
D. None of the above

Correct answer: A

Rationale: The correct answer is 'Carrying an impulse to the brain.' Afferent nerves are sensory nerves that carry signals from sensory receptors towards the central nervous system, including the brain. Choice B, 'Carrying an impulse away from the brain,' is incorrect as this describes efferent nerves which carry signals from the central nervous system to muscles and glands. Choice C, 'Carrying impulses to the motor neurons of the appendicular muscles,' is incorrect as it describes a different type of nerve function. Choice D, 'None of the above,' is incorrect as the correct definition of afferent nerve is indeed 'Carrying an impulse to the brain.'

4. You are working the 4 pm to 12 midnight evening shift. You are taking care of a group of patients. The supervising RN identifies 5 patients who get a medication at 'HS'. When will you give this medication?

A. After the dinner meal
B. Whenever requested
C. At the patient's bedtime
D. Before the end of the shift

Correct answer: C

Rationale: The correct answer is to give the medication at the patient's bedtime. 'HS' is a medical abbreviation that stands for 'hora somni,' which translates to 'at bedtime' or 'at the hours of sleep.' This timing ensures that the medication is administered appropriately to align with the patient's sleep schedule and maximize its effectiveness. Choices A, B, and D are incorrect because giving the medication after dinner, whenever requested, or before the end of the shift may not coincide with the intended purpose of the medication, potentially affecting its efficacy and patient outcomes.

5. During a heritage assessment, which question is most appropriate for the nurse to ask?

A. "Do you smoke?"?
B. "What is your religion?"?
C. "Do you have a history of heart disease?"?
D. "How many years have you lived in the United States?"?

Correct answer: D

Rationale: During a heritage assessment, it is crucial for the nurse to ask questions related to a person's country of ancestry, years in the United States, cultural practices, beliefs, and values. By asking about the number of years lived in the United States, the nurse can gain insights into the individual's cultural background and heritage. Options B, C, and A are not directly related to assessing heritage. Asking about religion only addresses one aspect of heritage, while smoking history and health history do not provide a comprehensive view of a person's heritage.
