In addition to assessing peripheral pulses and auscultating the patient’s heart and lung sounds, which action will be implemented by the nurse before a cardiac catheterization? Select all that apply. One, some, or all responses may be correct.

Choice A Reason:

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.

Choice B Reason:

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.

Choice C Reason:

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.

Choice D Reason:

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.

Choice E Reason:

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.

Choice A: Lean on your back with your knees bent.

Reason: This instruction is incorrect. Pursed lip breathing is typically performed in a seated position with the neck and shoulders relaxed. Lying on your back with knees bent is not a recommended position for this breathing technique.

Choice B: Use your abdominal muscles to squeeze air out of your lungs.

Reason: This instruction is correct. Using the abdominal muscles helps to expel air more effectively from the lungs, which is a key component of pursed lip breathing. This technique helps to improve ventilation and reduce the work of breathing.

Choice C: Breathe out slowly without puffing your cheeks.

Reason: This instruction is correct. Breathing out slowly through pursed lips without puffing the cheeks helps to keep the airways open longer, allowing more air to be expelled from the lungs. This technique is particularly beneficial for individuals with chronic obstructive pulmonary disease (COPD) or other respiratory conditions.

Choice D: Focus on inhaling and holding your breath as long as you can.

Reason: This instruction is incorrect. The focus of pursed lip breathing is on controlled exhalation rather than holding the breath. Inhaling should be done slowly through the nose, and exhaling should be prolonged through pursed lips.

Choice E: Exhale at least twice the amount of time it took to breathe in.

Reason: This instruction is correct. The exhalation phase should be longer than the inhalation phase, typically taking at least twice as long. This helps to improve the efficiency of breathing and reduce shortness of breath.

Choice F: Open your mouth and breathe deeply.

Reason: This instruction is incorrect. Pursed lip breathing involves breathing in through the nose and exhaling through pursed lips. Opening the mouth and breathing deeply is not part of this technique.
