A nurse is reviewing evidence-based practice principles about administration of oxygen therapy with a newly licensed nurse.
Which of the following actions should the nurse include?
Regulate the flow rate by aligning the rate with the top of the ball inside the flow meter.
Regulate oxygen via nasal cannula at a flow rate of no more than 6 L/min.
Ensure the reservoir bag of a partial rebreathing mask remains deflated.
Use petroleum jelly to lubricate the patient’s nares, face, and lips.
The Correct Answer is B
Choice A rationale
Regulating the flow rate by aligning the rate with the top of the ball inside the flow meter is a common practice in oxygen therapy. However, this action is not the most critical aspect to include when reviewing evidence-based practice principles about administration of oxygen therapy with a newly licensed nurse.
Choice B rationale
Regulating oxygen via nasal cannula at a flow rate of no more than 6 L/min is indeed an important aspect of oxygen therapy. Oxygen delivered at higher rates using a traditional nasal cannula can dry out sinus passages and lead to nosebleeds. Nasal cannula is typically started at 2L/min and then titrated upwards to as high as 6L/min, although 2-4L/min is ideal. This delivers 25-40% FIO2, depending upon their respiratory rate, tidal volume, and amount of mouth breathing. Therefore, this action should be included when educating a newly licensed nurse about the administration of oxygen therapy.
Choice C rationale
Ensuring the reservoir bag of a partial rebreathing mask remains deflated is not a recommended practice. A partial rebreathing mask is a face mask with a reservoir bag that delivers moderate to higher concentrations of oxygen. Frequent inspection of the reservoir bag is required to ensure that it remains inflated; if it is deflated, exhaled air collects in it, which results in the patient rebreathing large amounts of exhaled carbon dioxide. Therefore, this action should not be included when educating a newly licensed nurse about the administration of oxygen therapy.
Choice D rationale
Using petroleum jelly to lubricate the patient’s nares, face, and lips is not recommended. Even though use of intranasal petroleum jelly is common, it is not recommended. The heaviness of the base does not allow normal secretion and/or absorption of fluids or medications. Vitamin E oil is a much more appropriate and equally available remedy. This lighter nonpetroleum lubricant has a natural emollient effect. Therefore, this action should not be included when educating a newly licensed nurse about the administration of oxygen therapy.

Correct Answer is C
Explanation
Choice A rationale: Client 1 is admitted with a new diagnosis of rheumatoid arthritis. While this condition can cause discomfort and requires management, it is a chronic condition that does not typically present an immediate threat to the client’s health. Therefore, while this client will need to be assessed and their care plan will need to be adjusted to manage their new diagnosis, they are not the highest priority at this time.
Choice B rationale: Client 2 has a history of hyperlipidemia and has been administered Atorvastatin 20 mg PO as prescribed. Hyperlipidemia is a chronic condition that requires ongoing management, but it does not typically present an immediate threat to the client’s health. The fact that the client has been administered their medication as prescribed suggests that their condition is currently being managed effectively. Therefore, while this client will need to be monitored to ensure that their medication continues to be effective, they are not the highest priority at this time.
Choice C rationale: Client 3 is 1 day postoperative and reports pain as 8 on a scale of 0 to 10, even after Morphine 5 mg subcutaneous was administered as prescribed. This indicates that the client’s pain is not well controlled and could be a sign of complications. Therefore, immediate assessment is required. This client should be the nurse’s highest priority.
Choice D rationale: Client 4 is admitted with a new diagnosis of heart failure. Heart failure is a serious condition that can have life- threatening complications. However, the fact that this is a new diagnosis suggests that the client’s condition is not yet severe enough to require immediate intervention. Therefore, while this client will need to be assessed and their care plan will need to be adjusted to manage their new diagnosis, they are not the highest priority at this time.
Choice E rationale: Client 5 has a stage 2 pressure injury on the left heel. Pressure injuries can lead to serious complications, including infection and tissue necrosis. However, a stage 2 pressure injury is a relatively minor injury that is unlikely to present an immediate threat to the client’s health. Therefore, while this client will need to be assessed and their care plan will need to be adjusted to manage their pressure injury, they are not the highest priority at this time.
Choice F rationale: Client 6 is admitted with a new diagnosis of diabetes mellitus. Diabetes is a chronic condition that requires ongoing management. However, the fact that this is a new diagnosis suggests that the client’s condition is not yet severe enough to require immediate intervention. Therefore, while this client will need to be assessed and their care plan will need to be adjusted to manage their new diagnosis, they are not the highest priority at this time.
Correct Answer is C
Explanation
Choice A rationale
Tuberculosis is a serious infectious disease that affects the lungs. However, it does not typically cause lung hyperinflation.
Choice B rationale
Bronchitis is an inflammation of the bronchial tubes. While it can cause symptoms similar to those described, it does not typically cause lung hyperinflation or localized pneumonia in the left upper lobe.
Choice C rationale
Pneumonia is an infection that inflames the air sacs in one or both lungs. The client’s symptoms of a productive cough with thick yellow sputum, crackles in the left upper lobe, and decreased breath sounds at bases bilaterally are consistent with pneumonia. The chest x-ray showing left upper lobe pneumonia confirms this diagnosis.
Choice D rationale
Asthma is a condition in which a person’s airways become inflamed, narrow and swell, and produce extra mucus, which makes it difficult to breathe. While asthma can cause lung hyperinflation, it does not typically cause localized pneumonia in the left upper lobe.
