Nursing Elites

1. When caring for a patient with a chest tube, which nursing action is most important?

• A. Clamping the chest tube every 2 hours to prevent air leaks
• B. Keeping the drainage system below chest level
• C. Emptying the drainage system every hour to prevent backflow
• D. Removing the chest tube when drainage decreases significantly

Correct answer: B

Rationale: The most crucial nursing action when caring for a patient with a chest tube is to keep the drainage system below chest level (choice B). This position helps ensure proper drainage and prevents backflow of fluid or air into the pleural space, promoting optimal functioning of the chest tube. Clamping the chest tube every 2 hours (choice A) is incorrect as it can obstruct the drainage system and lead to complications. Emptying the drainage system every hour (choice C) is unnecessary unless there are specific clinical indications. Removing the chest tube when drainage decreases significantly (choice D) is also incorrect as the decision should be based on overall clinical assessment rather than drainage amount alone.

2. A child with glomerulonephritis is admitted in the acute edematous phase. Based on this diagnosis, which nursing intervention should the PN plan to include in the child's plan of care?

• A. Recommend parents bring favorite snacks
• B. Encourage ambulation daily to the playroom
• C. Measure blood pressure every 4 to 6 hours
• D. Offer a selection of fresh fruit for each meal

Correct answer: C

Rationale: The correct answer is to measure blood pressure every 4 to 6 hours. In glomerulonephritis, monitoring blood pressure is crucial as hypertension is a common complication. This helps in assessing the child's condition and response to treatment. Choice A, recommending parents bring favorite snacks, is not related to managing glomerulonephritis. Choice B, encouraging ambulation daily to the playroom, may not be appropriate during the acute edematous phase when the child may be experiencing fluid overload. Choice D, offering a selection of fresh fruit for each meal, is not directly relevant to managing the complications of glomerulonephritis.

3. What is the function of the enzyme lactase in the digestive system?

• A. Breaks down lactose into glucose and galactose
• B. Breaks down proteins into amino acids
• C. Converts starch into maltose
• D. Breaks down fats into fatty acids

Correct answer: A

Rationale: The correct answer is A: 'Breaks down lactose into glucose and galactose.' Lactase is an enzyme in the small intestine that specifically breaks down lactose, the sugar found in milk, into glucose and galactose for absorption. Choice B is incorrect because proteins are broken down into amino acids by protease enzymes. Choice C is incorrect because the enzyme amylase converts starch into maltose. Choice D is incorrect as lipase enzymes break down fats into fatty acids.

4. Based on the principle of asepsis, which situation should the nurse consider to be sterile?

• A. A one-inch border around the edges of a sterile field set up in the operating room
• B. A sterile glove that the nurse thinks might have touched her hair
• C. A wrapped, unopened sterile 4x4 gauze pad placed on a damp tabletop
• D. An open sterile Foley catheter kit set up on a table at the nurse's waist level

Correct answer: D

Rationale: The correct answer is D because an open sterile Foley catheter kit set up at waist level is considered sterile if it has not been contaminated. Choice A is incorrect because the one-inch border around a sterile field is considered non-sterile. Choice B is incorrect because a sterile glove that might have touched the nurse's hair is likely contaminated. Choice C is incorrect because a wrapped, unopened sterile gauze pad placed on a damp tabletop may have become contaminated.

5. What is the best thing to say to a patient scheduled for cataract surgery who is concerned that the physician works on the correct eye?

• A. You are wearing an ID bracelet that will let the medical team know which eye to work on.
• B. When you are taken to the surgery area, the medical staff will confirm which eye needs the surgery.
• C. The surgeon will mark the correct eye before the cataract surgery based on your medical records.
• D. You will wear an ID bracelet, and the nurse will verify the eye scheduled for surgery by comparing it with your records and marking it with a permanent marker.

Correct answer: D

Rationale: The best response reassures the patient by explaining the process of verifying and marking the correct eye, a safety measure to prevent wrong-site surgery, directly addressing the patient’s concern. Choice A is close but implies the ID bracelet alone determines the correct eye, missing the verification process. Choice B talks about confirmation but lacks details about marking the correct eye. Choice C mentions the surgeon's record but does not specify the direct verification and marking process, unlike Choice D.
