Chapter 25 : Asepsis and Infection Control Questions
Question 1 of 5
When performing a dressing change requiring surgical asepsis, a nurse opens sterile supplies and dons sterile gloves. What additional action by the nurse is appropriate?
Correct Answer: A
Rationale: Avoiding splashing while pouring irrigant onto the sterile field is appropriate as moisture can contaminate the sterile field. Covering the nose and mouth with gloved hands during a sneeze would contaminate the gloves. Forceps soaked in disinfectant are not sterile. The outer 1 inch of the sterile field is considered contaminated, not sterile.
Question 2 of 5
The nurse on a medical-surgical unit is admitting a patient with a diagnosis of active tuberculosis. Which infection control precautions will the nurse put in place?
Correct Answer: B,C,D
Rationale: Airborne precautions are used for patients who have infections with small particles that spread through the air, for example, tuberculosis, varicella, and rubeola. An N95 respirator mask is worn and the patient placed in a private room, preferably with negative air pressure. Sterile gloves are used for procedures requiring surgical asepsis. Standard precautions are for all patient care when contact with blood or body fluids, nonintact skin, and mucous membranes are likely. Visitors must wear PPE, including a mask.
Question 3 of 5
Nursing students enrolled in a medical-surgical nursing course are learning about infection control measures. They have learned that nurses use droplet precautions for patients with which infections? Select all that apply.
Correct Answer: A,F
Rationale: Rubella, diphtheria, and adenovirus infection are illnesses transmitted by large-droplet particles; droplet precautions and standard precautions are indicated. Airborne precautions refer to small, infectious particles spread through the air; for example, tuberculosis, varicella, and rubeola. Contact precautions are used for patients who are infected or colonized by a multidrug-resistant organism (MDRO), such as MRSA.
Question 4 of 5
A nurse and health care provider are preparing for insertion of a central venous catheter when the patient accidentally touches the sterile field. What action will the nurse take next?
Correct Answer: C
Rationale: If a patient touches a sterile field, the nurse should discard all supplies and prepare a new sterile field. If the patient is restless or confused, the nurse obtains an assistant to hold the patient's hands and explain what is happening.
Question 5 of 5
When performing sterile wound irrigation and dressing change for a postoperative patient, a new graduate nurse creates a sterile field. Which actions require correction by the preceptor? Select all that apply.
Correct Answer: B,C
Rationale:
To add a sterile solution to a sterile field, the nurse opens the solution container according to directions and places the cap on the table away from the field with the edges up. The nurse then holds the bottle outside the edge of the sterile field with the label side facing the palm of the hand and pours from a height of 4 to 6 inches (10 to 15 cm) to prevent splashing. When donning sterile gloves, the thumb should not be held away from the glove to avoid contamination.
