A patient is to receive a continuous infusion of Diltiazem at 2.5 mg hr for Atrial fibrillation, The medication is supplied 125 mg of Diltlazem in 125 mL of IV fluid. At what rate should the nurse set the IV pump? (round to the nearest tenth)

Answer and Explanation

The Correct Answer is ["2.5"]

Ordered Dose: The doctor has prescribed Diltiazem at a rate of 2.5 mg per hour. This means the patient needs to receive 2.5 milligrams of Diltiazem every hour.

Medication Concentration: The medication is supplied as 125 mg of Diltiazem in 125 mL of fluid. This translates to a concentration of 1 mg of Diltiazem per 1 mL of solution.

Since the medication concentration is 1 mg/mL, delivering 2.5 mg of Diltiazem per hour requires infusing 2.5 mL of the solution per hour.

Therefore, the nurse should set the IV pump to deliver 2.5 mL/hr of the Diltiazem solution.

Correct Answer is A

Explanation

A) Assess the patient's neurological status and repeat vital signs:
In patients with a spinal cord injury (SCI) at T1, autonomic dysreflexia or neurogenic shock can lead to unstable vital signs, including hypotension and bradycardia. The most immediate concern in this scenario is to determine if the patient is experiencing neurogenic shock, which can result from the loss of sympathetic nervous system function below the level of the injury. By assessing the patient’s neurological status (such as checking for changes in motor function, sensation, or level of consciousness) and repeating vital signs, the nurse can gather the necessary data to make informed decisions about further interventions.

B) Ask the patient care tech to check on the patient:
While the patient care tech can assist with tasks, this is not the priority action. The nurse must immediately assess the patient's condition, particularly given the vital sign changes and the potential for a life-threatening situation like neurogenic shock. The nurse's clinical judgment and expertise are required to evaluate the situation appropriately.

C) Place the client in reverse Trendelenburg position:
Placing the patient in reverse Trendelenburg may help with hypotension in certain situations, but it is not the priority intervention for someone with a spinal cord injury at T1. In cases of neurogenic shock or autonomic dysreflexia, positioning alone will not correct the underlying issue.

D) Administer intravenous (IV) fluids to increase cardiac output:
While IV fluids may be necessary to treat hypotension in some situations, the nurse must first assess the patient’s neurological status and repeat vital signs to determine the cause of the hypotension and bradycardia. Administering IV fluids without understanding the underlying cause could be inappropriate or even harmful, particularly if the low blood pressure is related to neurogenic shock, which requires careful management.

A. hypoglycemic event often develops B. physical dependency on the drug develops over time. C. a heart block is likely to develop. D. status epileptic us may develop

Correct Answer is D

Explanation

A) Hypoglycemic event often develops:
Phenytoin is an anticonvulsant, and while it can affect glucose metabolism, hypoglycemia is not a typical consequence of abruptly stopping the drug. This is not a primary concern when discontinuing phenytoin therapy. Hypoglycemia is more commonly associated with medications like insulin or sulfonylureas, not anticonvulsants like phenytoin.

B) Physical dependency on the drug develops over time:
Phenytoin does not cause physical dependence in the way that some other substances (e.g., alcohol, opioids) can. While the body can become used to a medication over time, and withdrawal symptoms can occur, the risk of physical dependence is not the main reason why phenytoin should not be stopped suddenly.

C) A heart block is likely to develop:
Phenytoin is known to have effects on cardiac conduction, and it can cause heart rhythm disturbances like bradycardia or a prolonged PR interval, especially with toxicity. However, the risk of a heart block developing due to abrupt discontinuation of phenytoin is not the primary concern.

D) Status epilepticus may develop:
The most serious risk of suddenly stopping phenytoin, or any anticonvulsant, is the potential for status epilepticus. Status epilepticus is a medical emergency where seizures occur continuously without recovery in between, which can be life-threatening. Abruptly discontinuing phenytoin can lead to a rebound increase in seizure activity, which can result in status epilepticus.
