Nursing Elites

1. Which of the following is NOT a recommended method for preventing healthcare-associated infections (HAIs)?

• A. Handwashing with soap and water
• B. Proper use of personal protective equipment (PPE)
• C. Disinfecting and reusing sterile medical devices
• D. Using single-use sterile medical devices

Correct answer: C

Rationale: Disinfecting and reusing sterile medical devices is not a recommended method for preventing healthcare-associated infections (HAIs). Reusing sterile medical devices can increase the risk of infections due to inadequate sterilization or potential damage to the devices during the reprocessing process. Proper sterilization and disposal of single-use medical devices are essential in preventing the transmission of infections in healthcare settings. A) Handwashing with soap and water is a crucial method for preventing HAIs as it helps to remove and reduce the number of pathogens on the hands of healthcare workers, preventing the spread of infections. B) Proper use of personal protective equipment (PPE) such as gloves, gowns, masks, and eye protection is important in preventing the transmission of infections between patients and healthcare workers. C) Disinfecting and reusing sterile medical devices is not a recommended practice as it can lead to the transmission of infections if the devices are not adequately sterilized. Using single-use sterile medical devices helps to ensure that each patient receives a sterile device, reducing the risk of infections.

2. Of the individuals described below, who seems like the best applicant for the roommate advertisement?

• A. Frances is a research assistant in the science department and owns a Yorkshire terrier.
• B. Adelaide works in the humanities department and is seeking a three-month rental.
• C. Cosette is allergic to cigarette smoke and requires a quiet place to study.
• D. Felix is a graduate student in the history department and does not own a car.

Correct answer: C

Rationale: The best applicant for the roommate advertisement is Cosette. The ad specifies that the current occupants are quiet, the house is clean/smoke-free, and no pets are allowed. Cosette is allergic to cigarette smoke, indicating she is a non-smoker and prefers a smoke-free environment. She also needs a quiet place to study, aligning with the quiet environment mentioned in the ad. Additionally, the ad prefers long-term applicants, and Cosette's need for a quiet place to study implies she will likely remain for an extended period. Frances owning a Yorkshire terrier goes against the ad's 'no pets' policy. Adelaide seeking a three-month rental does not align with the preference for long-term applicants. Felix not owning a car is not relevant to the criteria set by the ad.

3. Identify the participial phrase in the following sentence: 'Running through the park, she spotted a squirrel.'

• A. Running
• B. Through the park
• C. She spotted
• D. A squirrel

Correct answer: B

Rationale: The correct answer is 'B: Through the park.' A participial phrase acts as an adjective and is formed from a verb. In this sentence, 'Running through the park' describes 'she' and functions as an adjective modifying the subject. Choice A 'Running' is incorrect because it is just the present participle without additional context to form a phrase. Choice C 'She spotted' is incorrect as it is a subject and a verb, not a participial phrase. Choice D 'A squirrel' is incorrect as it is a noun phrase, not a participial phrase.

4. What is the name of the microscopic finger-like projections that increase the surface area for absorption in the small intestine?

• A. Goblet cells
• B. Paneth cells
• C. Villi
• D. Crypts of Lieberkühn

Correct answer: C

Rationale: A) Goblet cells: Goblet cells are specialized cells that secrete mucus to protect the lining of the digestive tract. While important for maintaining the health of the intestines, goblet cells do not increase the surface area for absorption in the small intestine. B) Paneth cells: Paneth cells are specialized cells found in the small intestine that secrete antimicrobial peptides. They play a role in protecting the intestinal stem cells and maintaining the gut microbiota balance, but they do not increase the surface area for absorption. C) Villi: Villi are microscopic finger-like projections found in the small intestine that increase the surface area available for absorption of nutrients. Each villus contains blood vessels and lacteals (lymphatic vessels) that help absorb nutrients from digested food. D) Crypts of Lieberkühn: Crypts of Lieberkühn are small pits located between the villi

5. It is December, and you have not yet had a lu vaccine. What should you do if you are among the people for whom a vaccine is recommended?

• A. Call your doctor for an appointment and get the vaccine.
• B. Avoid other people as much as possible.
• C. Wait until next year and get a double dose.
• D. Contact your local public health board to inform them.

Correct answer: A

Rationale: If you are among the people for whom a flu vaccine is recommended, the best course of action is to call your doctor for an appointment and get the vaccine. Getting vaccinated can help protect you from getting the flu and reduce the spread of the virus to others. It is important to prioritize your health and take preventive measures, especially during the flu season.
