A nurse is preparing a heparin infusion for a client who was admitted to the facility with deep-vein thrombosis.

The prescription reads: 25,000 units of heparin in 0.9% sodium chloride 250 mL to infuse at 800 units/hr. What should be the infusion pump rate?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A rationale

Using an extension cord to watch television in the living room does not indicate effective learning about using a walker. Extension cords can create a tripping hazard, which is particularly dangerous for someone using a walker.

Choice B rationale

Hiring someone to trim the tree that overhangs the front porch stairs indicates an understanding of the need to remove potential obstacles that could interfere with the safe use of the walker.

Choice C rationale

Placing the alarm clock on the bedroom dresser does not demonstrate an understanding of how to use a walker safely. It does not address any of the key safety considerations associated with walker use.

Choice D rationale

Replacing the old throw rug in the kitchen with a new one does not necessarily indicate effective learning about using a walker. Throw rugs can be a tripping hazard for individuals using a walker, regardless of whether they are old or new.

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.
