A nurse is caring for a client who has COPD.
The following are the client’s vital signs: Temperature 38.6C (101.5° F), BP 114/86 mm Hg, Heart rate 99/min, Respiratory rate 32/min, Oxygen saturation 85% on room air.
Which three findings require follow-up?

Choice A rationale

Injecting 5 units of air into the bottle of regular insulin is the second step in the procedure. This is done after injecting air into the NPH insulin bottle. The purpose of this step is to pressurize the vial, making it easier to withdraw the insulin.

Choice B rationale

Withdrawing the correct dose of NPH insulin from the bottle is the last step in the procedure. This is done after withdrawing the regular insulin to prevent contamination of the regular insulin with the NPH insulin.

Choice C rationale

Injecting 10 units of air into the bottle of NPH insulin is the first step in the procedure. This is done before injecting air into the regular insulin bottle. The purpose of this step is to pressurize the vial, making it easier to withdraw the insulin.

Choice D rationale

Withdrawing the correct dose of regular insulin from the bottle is the third step in the procedure. This is done after injecting air into the regular insulin bottle and before withdrawing the NPH insulin. The purpose of this step is to ensure that the correct dose of regular insulin is administered.

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.
