A. QT interval
: Monitoring the QT interval is crucial when administering amiodarone because this drug can prolong the QT interval, increasing the risk of torsades de pointes, a potentially life-threatening form of ventricular tachycardia. The QT interval represents the time it takes for the heart’s ventricles to depolarize and repolarize, and prolongation can lead to arrhythmias. Regular monitoring helps in early detection and prevention of such adverse effects.
B. Heart rate
: Heart rate monitoring is essential when administering amiodarone because the drug can cause bradycardia (a slower than normal heart rate). Amiodarone affects the electrical conduction system of the heart, which can lead to significant changes in heart rate. Monitoring the heart rate ensures that any bradycardia is detected early and managed appropriately to prevent complications such as hypotension or heart failure.
C. Respiratory rate
: While respiratory rate monitoring is important in general patient care, it is not specifically necessary for monitoring the effects of amiodarone. Amiodarone primarily affects the heart’s electrical activity and has less direct impact on respiratory function. However, in cases of severe adverse reactions, such as pulmonary toxicity, respiratory monitoring may become relevant.
D. Heart rhythm
: Monitoring heart rhythm is vital when administering amiodarone because the drug is used to treat arrhythmias and can also cause new arrhythmias or exacerbate existing ones. Continuous ECG monitoring helps in detecting any abnormal heart rhythms early, allowing for timely intervention. This is particularly important in patients with a history of arrhythmias or those receiving high doses of amiodarone.
E. Urine output
: Urine output monitoring is not specifically necessary for patients receiving amiodarone. While maintaining adequate urine output is important for overall patient health, amiodarone does not typically affect renal function directly. Therefore, urine output monitoring is not a primary concern when administering this medication.

A postoperative client following a thyroidectomy suddenly develops difficulty breathing, stridor, and an increase in swelling of the anterior neck area. What should the nurse do first?
A. Activate the hospital’s emergency or rapid response system.
The first priority in this situation is to ensure the client’s airway is secure. Difficulty breathing and stridor indicate a potential airway obstruction, which can be life-threatening. Activating the hospital’s emergency or rapid response system ensures that the client receives immediate medical attention from a team equipped to handle such emergencies. This step is crucial to prevent respiratory arrest and other complications.
B. Place a heart monitor on the client and observe for dysrhythmias.
While placing a heart monitor on the client and observing for dysrhythmias is important, it is not the immediate priority in this scenario. The client’s airway and breathing take precedence over monitoring heart rhythms. Once the airway is secured and breathing is stabilized, then monitoring for dysrhythmias can be considered.
C. Ask the charge nurse to come see the client immediately.
Asking the charge nurse to come see the client immediately is a reasonable action, but it is not the most effective first step. The charge nurse may not have the necessary equipment or expertise to handle an acute airway obstruction. Activating the emergency or rapid response system ensures that a specialized team responds quickly.
D. Check the client’s blood pressure and heart rate.
Checking the client’s blood pressure and heart rate is important for overall assessment, but it is not the immediate priority when there is a potential airway obstruction. Ensuring the client can breathe is the most critical action. Vital signs can be checked once the airway is secured.
E. Provide a calm and assuring environment for the client.
Providing a calm and assuring environment for the client is beneficial for reducing anxiety, but it does not address the immediate threat to the client’s airway. While maintaining a calm environment is important, the nurse must first ensure the client’s airway is open and breathing is adequate.
F. Place the emergency cart at the bedside.
Placing the emergency cart at the bedside is a preparatory step that can be useful, but it is not the first action to take. The nurse should first activate the emergency or rapid response system to get immediate help. The emergency cart can be brought to the bedside by the responding team.

The nurse is caring for a patient on a telemetry unit who has a regular heart rhythm and rate of 60 beats/min; a P wave precedes each QRS complex, and the PR interval is 0.20 seconds. Additional vital signs are: blood pressure 118/68 mm Hg, respiratory rate 16 breaths/min, and temperature 98.8°F (37°C). All of these medications are available on the medication record. What action will the nurse take?
A. Continue to monitor.
: Continuing to monitor is the most appropriate action in this scenario. The patient has a regular heart rhythm and a heart rate of 60 beats per minute, which is within the normal range for sinus bradycardia. The PR interval is 0.20 seconds, which is at the upper limit of normal. The patient’s vital signs are stable, with a blood pressure of 118/68 mm Hg, a respiratory rate of 16 breaths per minute, and a temperature of 98.8°F (37°C). There are no signs of hemodynamic instability or symptoms that would necessitate immediate intervention. Therefore, ongoing monitoring is sufficient to ensure the patient’s condition remains stable.
B. Administer clonidine.
: Administering clonidine is not appropriate in this situation. Clonidine is an antihypertensive medication that can lower blood pressure and heart rate. Given that the patient’s blood pressure and heart rate are within normal ranges, administering clonidine could potentially cause hypotension and bradycardia, leading to adverse effects. Therefore, clonidine is not indicated for this patient.
C. Administer atropine.
: Administering atropine is not necessary for this patient. Atropine is used to treat symptomatic bradycardia, where the heart rate is abnormally slow and causing symptoms such as dizziness, hypotension, or syncope. In this case, the patient’s heart rate is 60 beats per minute, which is within the normal range for sinus bradycardia, and there are no symptoms indicating the need for atropine. Therefore, atropine is not required.
D. Administer digoxin.
: Administering digoxin is also not appropriate. Digoxin is a cardiac glycoside used to treat heart failure and certain types of arrhythmias, such as atrial fibrillation. It can slow the heart rate and increase the force of cardiac contractions. In this scenario, the patient does not have any indications for digoxin therapy, such as heart failure or atrial fibrillation, and their heart rate is already within the normal range. Therefore, digoxin is not indicated.

An adult client who has been experiencing a seizure for approximately 15 minutes is brought to the emergency department by private vehicle. Which intervention should the nurse implement first?
A. Administer levetiracetam intravenously.
: Administering levetiracetam intravenously is not the first intervention. While levetiracetam is an antiepileptic drug used to control seizures, it is not the first-line treatment for an ongoing seizure, especially one lasting as long as 15 minutes. The priority in this situation is to stop the seizure activity immediately to prevent further complications, such as neuronal damage or status epilepticus. Levetiracetam may be used later for maintenance therapy, but it is not the initial emergency intervention.
B. Obtain a STAT electroencephalogram.
: Obtaining a STAT electroencephalogram (EEG) is important for diagnosing and understanding the type of seizure activity, but it is not the first intervention. The immediate priority is to stop the seizure. An EEG can be performed after the seizure has been controlled to assess brain activity and guide further treatment. Delaying the administration of an anticonvulsant to perform an EEG could result in prolonged seizure activity and increased risk of complications.
C. Administer lorazepam intravenously.
: Administering lorazepam intravenously is the most appropriate first intervention. Lorazepam is a benzodiazepine that acts quickly to stop seizure activity. It is the drug of choice for treating status epilepticus and prolonged seizures because of its rapid onset and effectiveness. Administering lorazepam helps to quickly terminate the seizure, reducing the risk of complications and stabilizing the patient for further evaluation and treatment.
D. Obtain a STAT 12-lead electrocardiogram.
: Obtaining a STAT 12-lead electrocardiogram (ECG) is not the first intervention. While an ECG can provide valuable information about the patient’s cardiac status, it does not address the immediate need to stop the seizure. The priority is to administer an anticonvulsant to terminate the seizure. Once the seizure is controlled, an ECG can be performed to assess any potential cardiac issues, especially if the patient has a history of cardiac problems or if the seizure was triggered by a cardiac event.
