Question 1

Hospital-acquired surgical site infections are commonly caused by (Select all that apply)

Accepted Answer

E. coli, Staphylococcus aureus, and Staphylococcus epidermidis are common causes of hospital-acquired surgical site infections. Streptococcus pneumoniae is more commonly associated with respiratory infections.

Question 2

Hospital-acquired infections of the respiratory system are commonly caused by (Select all that apply)

Accepted Answer

Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa are all known to cause hospital-acquired respiratory infections. E. coli is more commonly associated with gastrointestinal and urinary tract infections rather than respiratory infections.

Question 3

Staphylococcus aureus is a common cause of ____________ that are acquired in the hospital (Select all that apply)

Accepted Answer

The answer of Staphylococcus aureus is a common cause of...

Question 4

Surgical Site Infections (SSIs) account for what percentage of post-operative infections?

Accepted Answer

Surgical Site Infections (SSIs) account for approximately 38% of post-operative infections, making them a significant concern in post-surgical care.

Question 5

At what point in the SSI control timeline do patients get a nasal screening for MRSA colonization?

Accepted Answer

Pre-admission infection controls include screening for MRSA colonization.

Question 6

At what point in the SSI control timeline are gloves changed every 90-170 minutes?

Accepted Answer

Gloves are changed every 90-170 minutes during surgery as part of infection control measures to prevent surgical site infections (SSIs). This practice helps maintain a sterile environment and reduces the risk of contamination.

Question 7

At what point in the SSI control timeline is a patient educated about incision care?

Accepted Answer

Patients are typically educated about incision care during the post-operative infection control phase to ensure they understand how to care for their incision after surgery.

Question 8

Catheter-associated urinary tract infections (CAUTIs) account for approximately what percent of all HAIs?

Accepted Answer

CAUTIs account for approximately 40% of all healthcare-associated infections (HAIs).

Question 9

Which of the following statements about a PICC line are accurate? (Select all that apply)

Accepted Answer

A PICC line is used for long-term intravenous access, often for irritating drugs. It can lead to bloodstream infections, and pathogens in the bloodstream can cause complications like thrombophlebitis and cellulitis. The catheter tip is positioned in a large vein near the heart, not the bladder.

Question 10

The percentage of Central Line-Associated Bloodstream Infections (CLABSIs) has increased and now 70% of patients with one are not in the ICU. Which of the following is a required practice to reduce CLABSIs?

Accepted Answer

A) Use of maximum barrier precautions, B) Use of chlorhexidine for skin preparation, and D) Avoidance of femoral insertion sites are all evidence-based practices recommended to reduce the incidence of Central Line-Associated Bloodstream Infections (CLABSIs). These measures are part of a bundle approach to prevent infections related to central line insertion and maintenance. C) Use of double-lumen catheters is not specifically a required practice to reduce CLABSIs; the choice of catheter should be based on clinical need, and minimizing lumens is generally preferred to reduce infection risk.

Question 14

What is the average noncompliance rate for nurses who do not wash their hands?

Accepted Answer

Studies have shown that the average noncompliance rate for handwashing among healthcare workers, including nurses, is around 40%.

Question 15

After using the toilet, changing a diaper, prior to beginning food preparation, and before eating, hands should be washed with regular soap to achieve removal of ______________ of transient skin flora

Accepted Answer

Washing hands with regular soap is effective in removing 50-95% of transient skin flora, significantly reducing the risk of transmitting pathogens.

Question 16

In medical settings, hands should be washed with antimicrobial soap or alcohol gel in order to remove ___________ of transient skin flora as well as resident flora that may be removed

Accepted Answer

The answer of In medical settings, hands should be washed...

Question 17

Before surgical procedures, complete cleaning with antimicrobial soap and brush scrubbing plus holding hands above the level of the elbows will remove _____________of transient and removable resident flora

Accepted Answer

The combination of antimicrobial soap and brush scrubbing followed by holding hands above the level of the elbows is designed to remove 99.99% of transient and removable resident flora, significantly reducing the risk of surgical site infections.

Question 18

The 5 Moments of Hand Hygiene refers to the frequency of practicing hand hygiene during patient contact by the caregiver such as a nurse or aide. These moments include (Select all that apply)

Accepted Answer

The 5 Moments of Hand Hygiene, as defined by the World Health Organization, include: 1) before touching a patient, 2) before clean/aseptic procedures, 3) after body fluid exposure/risk, 4) after touching a patient, and 5) after touching patient surroundings. Option D is not included in these moments; it is a general hygiene practice but not specific to the 5 Moments of Hand Hygiene in healthcare settings.

Question 19

While alcohol gel cleanser is often more effective and convenient for health caregivers, only __________________can protect against the formation of endospores from bacteria like Clostridium, Closteroides and Bacillus.

Accepted Answer

Traditional soap and water cleansing is effective in physically removing dirt, bacteria, and viruses from the skin, including the spores formed by bacteria like Clostridium, Closteroides, and Bacillus. Alcohol-based hand sanitizers may not be as effective against these spores.

Question 20

To meet precaution standards for hand hygiene, ____________ is required.

Accepted Answer

Artificial fingernails can harbor pathogens and increase the risk of infection, especially for patients at high risk, making it crucial to avoid wearing them for proper hand hygiene.
