A nurse is reinforcing teaching with a client's family about home oxygen use via nasal cannula. Which of the following statements by a family member indicates an understanding of the teaching?
"We will frequently check the top of his ears for sores."
"We can turn the oxygen up to 10 when he has trouble breathing."
"We can use petroleum jelly to keep his nares moist."
"We will need to remove the nasal cannula when he is eating."
The Correct Answer is A
A. Frequently checking the top of the ears for sores is correct. The nasal cannula tubing can cause pressure injuries behind the ears over time. The family should check for redness or sores and use protective padding or adjust the tubing as needed.
B. Turning the oxygen up to 10 when the client has trouble breathing is incorrect. Oxygen flow rates should be adjusted only as prescribed by the provider. Increasing the flow rate without guidance can lead to complications, such as oxygen toxicity in clients with chronic respiratory conditions.
C. Using petroleum jelly to keep the nares moist is incorrect. Petroleum-based products are flammable and should not be used with oxygen therapy. Instead, a water-based lubricant should be used to prevent nasal dryness.
D. Removing the nasal cannula when eating is incorrect. Clients using a nasal cannula can continue wearing it while eating, as it allows them to receive oxygen continuously. If needed, a healthcare provider can recommend adjustments to oxygen flow during meals.

Correct Answer is C
Explanation
A. BUN 18 mg/dL is incorrect. A BUN (blood urea nitrogen) level of 18 mg/dL is within the normal range (typically 7–20 mg/dL) and does not indicate immediate concern in this context. An elevated BUN could indicate dehydration, but this level is not significantly elevated.
B. Serum creatinine 1.0 mg/dL is incorrect. Serum creatinine levels are also within normal limits for most adults, which is around 0.6–1.2 mg/dL, and this finding does not indicate a problem.
C. Urine output 12 mL/hr is correct. A urine output of 12 mL/hr is low and indicates oliguria, which is a concern in the context of dehydration. The normal urine output for an adult is at least 30 mL/hr. A decrease in urine output suggests that the kidneys are not receiving adequate blood flow, which could indicate severe dehydration and requires immediate attention from the provider.
D. Urine specific gravity 1.020 is incorrect. Urine specific gravity of 1.020 is within the normal range (typically 1.005–1.030) and indicates that the kidneys are concentrating urine appropriately, which is not a concerning finding in this case.
Correct Answer is B
Explanation
A. An entry on a nursing blog addressing wound healing: Nursing blogs can offer personal perspectives and experiences but may not always be evidence-based. The information can vary in quality and credibility.
B. A peer-reviewed journal article: This is correct. Peer-reviewed journal articles are the gold standard for evidence-based information because they have been evaluated by experts in the field and provide scientifically validated information.
C. First-hand experience with wound care products: While first-hand experience can be valuable, it is subjective and may not reflect the most current or broad evidence-based practices. It should be supplemented with research.
D. Information from a wound care product vendor: Although vendors may offer useful product-specific details, their information is often biased toward their own products and may not provide the most objective, evidence-based information available.
