A nurse is preparing to administer total parenteral nutrition (TPN) 1800 mL to infuse over 24 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["75"]
To calculate the infusion rate, divide the volume of fluid by the time in hours. In this case, 1800 mL / 24 hr = 75 mL/hr.
Round the answer to the nearest whole number and use a leading zero if it applies.
Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should set the IV pump to deliver 75 mL/hr.

Correct Answer is D
Explanation
The nurse should place a towel under the client's head to protect it from injury during the seizure. The nurse should also loosen any tight clothing, remove any objects that could harm the client, and maintain a patent airway.
Place the client in a prone position is wrong because it can compromise the client's breathing and increase the risk of aspiration. The nurse should place the client in a side-lying position after the seizure to facilitate drainage of oral secretions and prevent aspiration.
Holding the client's arms and legs still is wrong because it can cause injury to the client or the nurse. The nurse should not restrain or interfere with the client's movements during the seizure but rather ensure a safe environment and observe the seizure activity.
Leaving the client to get help is wrong because it can endanger the client's safety and well-being. The nurse should stay with the client during the seizure and call for assistance if needed, but not leave the client alone or unattended.
Correct Answer is D
Explanation
Choice A reason:
Administering an anticholinesterase medication is not the primary intervention during a myasthenic crisis. While these medications can improve muscle strength in myasthenia gravis, they are not sufficient in the event of a crisis.
Choice B reason:
Pursed lip breathing is a technique used to manage dyspnea but is not adequate for the acute management of a myasthenic crisis, which can involve respiratory muscle paralysis.
Choice C reason:
Vasoconstrictors are not used in the treatment of myasthenic crisis. This condition is not related to vascular issues but to neuromuscular transmission failure leading to respiratory failure.
Choice D reason:
Mechanical ventilation is the correct intervention as it provides the necessary respiratory support when the patient's respiratory muscles are too weak to maintain adequate ventilation.
