A nurse is caring for a client who has a prescription for 5 units of regular insulin and 10 units of NPH insulin to be mixed together and administered subcutaneously.
Determine the correct order of steps for this procedure.
Inject 5 units of air into the bottle of regular insulin.
Withdraw the correct dose of NPH insulin from the bottle.
Inject 10 units of air into the bottle of NPH insulin.
Withdraw the correct dose of regular insulin from the bottle.
The Correct Answer is C,A,D,B
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.

Correct Answer is B
Explanation
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.
Correct Answer is ["A","B","C","D"]
Explanation
Choice A rationale
Regular inspection of the cord for frays or tears is crucial to ensure the safe operation of the home oxygen concentrator. A damaged cord can pose a risk of electric shock or fire.
Choice B rationale
Keeping the unit at least 1.2 m (4 ft) away from a gas stove is important because oxygen supports combustion. An oxygen-rich environment can cause materials to ignite more easily and make fires burn at a faster rate.
Choice C rationale
Considering the purchase of a generator for power backup is a good idea. In case of a power outage, a backup power source would ensure the continuous operation of the oxygen concentrator, which is critical for patients who are dependent on supplemental oxygen.
Choice D rationale
Monitoring for signs of hypoxia is essential. Despite receiving oxygen therapy, a patient may still experience hypoxia if the oxygen flow rate is insufficient, or if there are issues with the equipment. Signs of hypoxia include shortness of breath, rapid breathing, restlessness, confusion, and cyanosis (bluish color of the skin, lips, or nails)12.
Choice E rationale
Choosing synthetic clothing and bedding is not recommended. Synthetic materials can build up static electricity, which can spark and cause a fire in an oxygen-enriched environment.
