Elderly patients are more prone to dehydration than younger people because the elderly ___________.
- A. drink more coffee and tea
- B. have more stomach mucus production
- C. have more saliva
- D. have less sense of thirst
Correct Answer: D
Rationale: Elderly patients are prone to dehydration because they have a lower and diminished sense of thirst. This reduced sensation of thirst makes them less likely to drink an adequate amount of fluids, leading to dehydration. While it is true that elderly individuals may also have changes such as decreased stomach mucus production and saliva production, these factors do not directly contribute to dehydration. Drinking more coffee and tea, as mentioned in choice A, is not a consistent behavior among all elderly individuals and is not a primary reason for their increased risk of dehydration.

Which of the following is a local sign of infection?
- A. Swelling
- B. Rapid pulse
- C. Fever
- D. High white blood count
Correct Answer: A
Rationale: A local sign of infection refers to symptoms that are specific to the area of infection. Swelling, heat, pain, and redness near the infected site are examples of local signs. In the context of infection, swelling occurs due to an accumulation of fluid and immune cells at the site of infection. Rapid pulse, fever, and high white blood count are more systemic responses to infection and not specific local signs. Rapid pulse can indicate systemic distress or sepsis, fever is a systemic response to infection, and high white blood count is a laboratory finding that suggests an immune response but is not a direct sign of infection at a specific site.
Which risk factor places patients and residents at the greatest risk for falls?
- A. Old age
- B. Middle age
- C. Pneumonia
- D. COPD
Correct Answer: A
Rationale: Old age is a significant risk factor for falls as elderly individuals are more prone to falls due to factors like decreased balance, muscle strength, and vision. Middle age is less associated with falls compared to old age. Pneumonia and COPD are medical conditions that are not direct risk factors for falls, unlike aging which significantly increases the risk of falls.
Asepsis is defined as ________________.
- A. the absence of all microorganisms
- B. the absence of disease-causing germs
- C. a urinary infection
- D. a pathogenic infection
Correct Answer: B
Rationale: Asepsis is defined as the absence of disease-causing germs. It is surgical asepsis that is defined as the absence of all microorganisms, including spores. A pathogenic infection is an invasion of the body by a pathogen, or disease-causing germ, and a urinary infection is only one type of infection.
Your patient has been diagnosed with a left ankle sprain. On the discharge instructions, the physician has prescribed the RICE protocol. This acronym stands for:
- A. Rest, Ice, Compression, Elevation
- B. Radiology, Ice, Compression, Elevation
- C. Rest, Ice, Cast, Elevation
- D. Radiology, Ice, Cast, Elevation
Correct Answer: A
Rationale: The correct answer is Rest, Ice, Compression, Elevation. This acronym, RICE, is commonly used for the treatment of injuries like an ankle sprain. Rest allows the injured area to heal, Ice helps reduce swelling and pain (20 minutes on each hour while awake), Compression is usually achieved with an elastic bandage to minimize swelling, and Elevation of the foot above the level of the heart assists in reducing swelling and promoting healing. Choices B, C, and D are incorrect because they include irrelevant terms like Radiology and Cast, which are not part of the standard treatment protocol for an ankle sprain.
Sinusitis is caused by:
- A. Bacteria
- B. Fungus
- C. Virus
- D. Any of the above
Correct Answer: D
Rationale: Sinusitis can be caused by bacteria, viruses, or fungi. While bacterial infections are the most common cause, viral or fungal infections can also lead to sinusitis. Therefore, the correct answer is 'Any of the above.' Choices A, B, and C are incorrect because they only represent individual causes of sinusitis, whereas choice D encompasses all possible causes.
