What are some nursing considerations for nitroglycerin?
Nursing Implications:
- Check blood pressure and pulse before each administration of NTG–blood pressure can drop precipitously after a single dose.
- NTG is highly unstable and should be stored in light resistant container in cool environment (not the refrigerator).
What should you assess before administering nitroglycerin?
Assess heart rate, ECG, and heart sounds, especially during exercise (See Appendices G, H). Report fast heart rate (tachycardia) or symptoms of other arrhythmias, including palpitations, chest discomfort, shortness of breath, fainting, and fatigue/weakness.
What are the nursing considerations for isosorbide?
Report any rhythm disturbances (tachycardia, bradycardia, others) or symptoms of increased arrhythmias, including palpitations, chest discomfort, shortness of breath, fainting, and fatigue/weakness. Assess dizziness and syncope that might affect gait, balance, and other functional activities (See Appendix C).
When administering nitroglycerin The nurse should watch for?
The nurse should monitor the patient’s blood pressure and heart rate. After 5 minutes, the pain level should be reassessed and a second dose of nitroglycerin administered if the patient’s chest pain continues.
What is a contraindication to nitrate administration?
Nitroglycerin is contraindicated in patients that have reported allergic symptoms to the medication. [18] Known history of increased intracranial pressure, severe anemia, right-sided myocardial infarction, or hypersensitivity to nitroglycerin are contraindications to nitroglycerin therapy.
What do you need to monitor when administering nitroglycerin IV?
Use Caution/Monitor. Both drugs lower blood pressure. Monitor blood pressure. Monitor Closely (1)nitroglycerin IV, bretylium.
What is a contraindication to nitrate administration ACLS?
“Nitrates should not be given to patients with hypotension, marked bradycardia or tachycardia, RV infarction, or 5’phosphodiesterase inhibitor use within the previous 24 to 48 hours.”
How do nitrates affect heart rate?
Essentially, nitrates dilate – that is, widen or relax – the arteries and the veins not only in the heart but also elsewhere in the body. By dilating the blood vessels of the heart, nitrates can reduce the stress on the heart by improving blood flow to the heart muscle.
Why do nitrates cause hypotension?
The efficacy of nitrates is attributed to their vasodilator effects, especially their peripheral venodilating properties. A decrease in venous return and, to a certain extent, in arteriolar resistance usually causes hypotension of variable degrees.
Why do nitrates cause tachycardia?
At higher doses, the vasodilator effect is exerted on arteries and, although it reduces peripheral vascular resistance (afterload) and blood pressure, it can also produce reflex tachycardia which annihilates the reduction of MVO2. Finally, nitrates exert anti-platelet aggregation effects.
How do nitrates affect blood pressure?
Dietary nitrate exerts potent and long-lasting blood pressure decrease in hypertension that is sustained with once a day dosing for 4 weeks. Daily dietary nitrate ingestion provides additional blood pressure lowering beyond conventional pharmacotherapy.
What is a common side effect of nitrates?
The most common side effects of nitrates include headaches, dizziness or light-headedness, flushing or a warm feeling in the face.
What is a contraindication for nitrate administration?
What is a contraindication of nitroglycerin?
CONTRAINDICATIONS. Nitroglycerin is contraindicated in patients who are allergic to it. Sublingual nitroglycerin therapy is contraindicated in patients with early myocardial infarction, severe anemia, increased intracranial pressure, and those with a known hypersensitivity to nitroglycerin.
What are the adverse effects of nitrates?
What are the side effects?
- Dizziness.
- Headaches.
- Flushing of your face and neck.
- Upset stomach or throwing up.
- Low blood pressure (hypotension)
- Irregular heart rhythms (arrhythmia)
What are the important teaching points for patients receiving antianginal nitrates?
Instruct patients to avoid eating or smoking during administration as this may alter absorption. Patients should sit during administration to decrease the risk for injury due to the possibility of hypotension, dizziness, and weakness.
When administering GTN what precautions and guidelines should the nurse follow?
– Nitrates should be taken while seated because a drop in blood pressure can result in fainting. – Avoid excessive alcohol intake. – Ensure that patients are aware that this medication may cause headache and that simple analgesics can be used to relieve this.
