Nurse has prepared sterile field for assisting provider with chest tube insertion. Which should nurse recognize as contaminating sterile field?
- A. Provider drops sterile instrument onto near side of sterile field
- B. Nurse moistens cotton ball with sterile NS & places it on sterile field
- C. Procedure is delayed 1h because provider receives emergency call
- D. Nurse turns to speak to someone who enters through door behind nurse
- E. Client's hand brushes against outer edge of sterile field
Correct Answer: B,C,D
Rationale: The correct answers are B, C, and D.
B: Moistening a cotton ball with sterile NS and placing it on the sterile field introduces moisture and potentially non-sterile material, contaminating the field.
C: Delaying the procedure for an hour increases the risk of airborne contaminants settling on the sterile field.
D: Turning to speak to someone who enters behind the nurse can lead to inadvertent contact with non-sterile areas, contaminating the field.
Incorrect choices:
A: While dropping a sterile instrument close to the field is not ideal, it may not necessarily contaminate the field unless it actually touches it.
E: Client's hand brushing against the outer edge of the field is a potential contamination point, but it does not directly contaminate the sterile field.

When entering client's room to change dressing
- A. nurse notes client is coughing & sneezing. When preparing sterile field
- B. it's important the nurse...
- C. Keep sterile field at least 6 ft away from client's bedside
- D. Instruct client to not cough/sneeze during dressing change
- E. Place mask on client to limit spread of microorganisms into surgical wound
Correct Answer: C
Rationale: The correct answer is C because keeping the sterile field at least 6 feet away from the client's bedside helps to maintain its integrity and prevent contamination. Placing the field further away reduces the risk of microorganisms reaching it during the dressing change procedure. Choice A is incorrect as the nurse should address the client's coughing and sneezing before proceeding with the dressing change. Choice B is vague and does not directly relate to maintaining sterility. Choice D is ineffective as instructing the client to stop coughing or sneezing is unrealistic. Choice E, while a good practice in general, does not directly address the maintenance of the sterile field.
A nurse caring for a client with a new prescription checks the electronic database for medication information. Which component of critical thinking is the nurse using?
- A. Knowledge
- B. Experience
- C. Intuition
- D. Competence
Correct Answer: A
Rationale: The correct answer is A: Knowledge. Checking the electronic database for medication information involves accessing and utilizing factual information and data, which is a key component of knowledge in critical thinking. This process requires the nurse to gather relevant information, analyze it, and apply it to make informed decisions. Experience (B) and competence (D) are related to skills and proficiency but do not specifically focus on accessing information. Intuition (C) involves a gut feeling or instinct, which is different from actively seeking and using information.
A nurse is caring for an immobile patient. Which metabolic alteration will the nurse monitor for in this patient?
- A. Increased appetite
- B. Increased diarrhea
- C. Increased metabolic rate
- D. Altered nutrient metabolism
Correct Answer: D
Rationale: The correct answer is D: Altered nutrient metabolism. Immobility can lead to changes in nutrient metabolism due to decreased physical activity and muscle mass. The body may start breaking down muscle tissue for energy, leading to altered nutrient metabolism.
A: Increased appetite is not directly related to immobility and is unlikely to be a metabolic alteration seen in this patient.
B: Increased diarrhea is more likely related to gastrointestinal issues rather than a direct metabolic alteration due to immobility.
C: Increased metabolic rate is unlikely in an immobile patient as physical activity is decreased.
Therefore, D is the correct choice as it directly relates to the metabolic changes associated with immobility.
Nurse is caring for client who presents with linear clusters of fluid-containing vesicles with some crusting. Which should nurse suspect?
- A. Allergic reaction
- B. Ringworm
- C. Systemic lupus erythematosus
- D. Herpes zoster
Correct Answer: D
Rationale: The correct answer is D: Herpes zoster. The description of linear clusters of fluid-containing vesicles with some crusting is characteristic of herpes zoster, also known as shingles. This condition is caused by the reactivation of the varicella-zoster virus, which initially causes chickenpox. The linear distribution along a dermatome is a key feature of herpes zoster. Allergic reaction (A) typically presents with generalized rash and itching, not linear clusters of vesicles. Ringworm (B) presents as circular, scaly lesions, not linear clusters of vesicles. Systemic lupus erythematosus (C) is an autoimmune disease that presents with a variety of symptoms, but not linear clusters of vesicles.
Nurse is talking with 45 yo client with no specific family hx of cancer or DM, about planning routine screenings. Which client statement indicates client understands how to proceed?
- A. So I don't need colon cancer procedure for another 2-3 yrs
- B. For now, I should continue to have mammogram each year
- C. B/c doctor just did pap smear, I'll come back next year for another
- D. I had my blood glucose test last year so I won't need it again till next year
Correct Answer: B
Rationale: The correct answer is B. The client's statement indicates an understanding of the recommended screening guideline for mammograms for a 45-year-old individual with no specific family history of cancer. Yearly mammograms are typically recommended starting at age 40 for early detection of breast cancer. Choice A is incorrect as colon cancer screening is recommended starting at age 45-50, not in 2-3 years. Choice C is incorrect as Pap smears are typically recommended every 3-5 years, not yearly. Choice D is incorrect as blood glucose testing is usually recommended annually for individuals at risk for diabetes.
