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 B
Explanation
Choice A rationale
While colonoscopy is a screening method for colon cancer, it is not typically recommended to begin at age 60 for individuals at average risk. Instead, colonoscopy screening is usually recommended to begin at age 50 and continue every 10 years if no polyps are found.
Choice B rationale
The recommendation for an average risk individual for colon cancer is to have a fecal occult blood test every year. This test checks for hidden blood in the stool, which can be an early sign of cancer.
Choice C rationale
Sigmoidoscopy every 10 years is another screening option for colon cancer. However, it only examines the rectum and lower third of the colon, whereas a colonoscopy examines the entire colon.
Choice D rationale
Blood tests are not typically used as a primary screening method for colon cancer. They may be used in conjunction with other tests, but a blood sample alone is not sufficient for screening.
Correct Answer is C
Explanation
Choice A rationale: Group discussions represent the cognitive and affective domains of learning. They allow participants to share knowledge and feelings but do not involve the physical manipulation required for psychomotor skills.
Choice B rationale: Query and answer sessions focus on the cognitive domain. They address the learner's need for information and clarification of facts rather than the development of physical coordination or manual dexterity.
Choice C rationale: Practice sessions are the definitive psychomotor approach. They require the learner to physically perform a task, such as changing an ostomy appliance, to develop muscle memory and technical proficiency.
Choice D rationale: Role play primarily addresses the affective domain by exploring attitudes and behaviors. While it involves action, it focuses on social and emotional responses rather than specific technical or manual tasks.
