A nurse is preparing to administer 4,000 units of heparin subcutaneously to a client who has deep-vein thrombosis. Available is heparin 10,000 units/mL. How many mL of heparin should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.4"]
To answer this question, we need to use the formula for calculating the dosage of medication:
Dose ordered / Dose on hand = Amount to administer
The calculation is: 4,000 units / 10,000 units/mL = 0.4 mL.

Correct Answer is ["A","C","E"]
Explanation
Choice A rationale:
The nurse should teach the guardian to shake the device prior to administration to ensure that the medication is well mixed and delivered in the right dose.
Choice B rationale:
Soaking the inhaler in water is not a recommended action as this can damage the device and affect its function.
Choice C rationale:
The nurse should also teach the guardian to use a spacer with the inhaler, which is a device that attaches to the mouthpiece and helps deliver the medication more effectively to the lungs.
Choice D rationale:
The nurse should also not teach the guardian to have the child take one inhalation as needed for shortness of breath, as fluticasone is a long-acting corticosteroid that is used for maintenance therapy and prevention of asthma symptoms, not for acute relief. The child should have a separate rescue inhaler, such as albuterol, for quick relief of bronchospasm.
Choice E rationale
The nurse should instruct the guardian to rinse the child's mouth with water after using the inhaler to prevent oral candidiasis, which is a fungal infection that can occur from the steroid medication.
