A ___________ is administered to produce immunity to a specific disease.
- A. Vesicle
- B. Vector
- C. Vacuum
- D. Vaccine
Correct Answer: D
Rationale: The correct answer is D: Vaccine. A vaccine is specifically designed to produce immunity to a particular disease by stimulating the body's immune system to recognize and respond to the disease-causing agent. Vaccines contain weakened or inactivated forms of the pathogen, allowing the immune system to develop memory cells for future protection.
Rationale:
A: Vesicle is a small blister-like structure and is not used to produce immunity.
B: Vector is an organism that transmits a pathogen but is not directly involved in producing immunity.
C: Vacuum is a space entirely devoid of matter and is not related to immunity or disease prevention.

Which of the following is a guideline for a nursing assistant who is caring for a resident with an IV line?
- A. The NA should disconnect the IV line when the bag is empty.
- B. The NA should not measure blood pressure on an arm with an IV.
- C. The NA should only get the IV site wet during the resident's bath.
- D. The NA should lower the IV bag below the site for short intervals.
Correct Answer: B
Rationale: The correct answer is B because measuring blood pressure on an arm with an IV can cause inaccurate readings and potential damage to the IV line. It is important to avoid placing any unnecessary pressure or restriction on the IV site to prevent complications such as infiltration or dislodgement. This guideline ensures the safety and well-being of the resident.
Incorrect choices:
A: Disconnecting the IV line when the bag is empty can interrupt the flow of medication or fluids, leading to potential harm to the resident.
C: Getting the IV site wet during the resident's bath can increase the risk of infection or dislodgement of the IV line.
D: Lowering the IV bag below the site for short intervals can cause improper flow rate and lead to complications like air embolism.
The most common type of peripheral vascular disease (PVD) is
- A. Phlebitis
- B. Myocardial infarction (MI)
- C. Peripheral arterial disease (PAD)
- D. Coronary artery disease (CAD)
Correct Answer: C
Rationale: The correct answer is C: Peripheral arterial disease (PAD). PAD is the most common type of peripheral vascular disease, characterized by the narrowing or blockage of arteries that supply blood to the extremities. This leads to reduced blood flow and can cause pain, numbness, and other symptoms. Phlebitis (A) refers to inflammation of veins, while myocardial infarction (B) and coronary artery disease (D) specifically involve the heart and its blood supply, not the peripheral arteries. So, C is correct as it directly relates to narrowing/blockage of peripheral arteries, distinguishing it from the other choices.
Which of the following is a guideline for a nursing assistant who is caring for a resident with an IV line?
- A. The NA should disconnect the IV line when the bag is empty.
- B. The NA should not measure blood pressure on an arm with an IV.
- C. The NA should only get the IV site wet during the resident's bath.
- D. The NA should lower the IV bag below the site for short intervals.
Correct Answer: B
Rationale: The correct answer is B: The NA should not measure blood pressure on an arm with an IV. This is because measuring blood pressure on an arm with an IV can disrupt the IV line, leading to potential complications such as infiltration or dislodgment. It is important to avoid applying pressure or constricting the area around the IV site to ensure proper flow of fluids and medication.
Explanation of other choices:
A: The NA should not disconnect the IV line when the bag is empty as this can lead to air entering the line, causing air embolism.
C: The NA should avoid getting the IV site wet during the resident's bath to prevent infection or dislodgment of the IV catheter.
D: Lowering the IV bag below the site for short intervals is not recommended as it can cause an uneven flow rate and compromise the effectiveness of IV therapy.
Residents in _____ are usually more independent and do not need skilled care.
- A. Acute care facilities
- B. Assisted living facilities
- C. Subacute care facilities
- D. Hospice facilities
Correct Answer: B
Rationale: The correct answer is B: Assisted living facilities. Residents in assisted living facilities typically require minimal assistance with daily activities and are more independent compared to those in acute care, subacute care, and hospice facilities. Assisted living facilities provide a level of care that promotes independence while still offering support when needed. Acute care facilities (A) provide medical care for short-term conditions, subacute care facilities (C) offer more intensive care than assisted living, and hospice facilities (D) provide end-of-life care which involves more specialized and intensive support.
One guideline for a nursing assistant who is caring for a resident who has a mental health disorder is to
- A. Take any suicide threat seriously
- B. Disregard a loss of appetite
- C. Avoid talking to the resident
- D. Ignore dilated pupils
Correct Answer: A
Rationale: The correct answer is A: Take any suicide threat seriously. This is crucial as individuals with mental health disorders are at a higher risk of suicide. Ignoring such threats can have serious consequences. Disregarding loss of appetite can lead to overlooking potential signs of deterioration in the resident's mental health. Avoiding communication with the resident can exacerbate feelings of isolation and worsen the mental health condition. Ignoring dilated pupils may overlook signs of drug use or potential medical issues. Overall, prioritizing the safety and well-being of the resident by taking suicide threats seriously is essential in providing appropriate care.
