A nurse is caring for a client. Exhibits Complete the following sentence by using the list of options. After notifying the provider, the nurse should first administer dropdownand thendropdown.

After notifying the provider, the nurse should first administer oxygen at 2L/min via nasal cannula and then administer sublingual nitroglycerin. Rationale: Step 1: Administer Oxygen at 2L/min via Nasal Cannula The client's oxygen saturation has dropped from 97% to 92% on room air, which indicates potential myocardial oxygen demand exceeding supply. Oxygen therapy helps improve myocardial oxygenation, which is crucial for clients with suspected acute coronary syndrome (ACS). Step 2: Administer Sublingual Nitroglycerin The client’s chest pain has worsened (increased from 4/10 to 7/10) and is associated with shortness of breath, which suggests possible myocardial ischemia. Nitroglycerin causes vasodilation, reducing myocardial oxygen demand and improving coronary perfusion. It is a first-line treatment for suspected angina or acute coronary syndrome (ACS). Incorrect Options Step 1: Prepare the client for cardiac catheterization: While a catheterization may be necessary, immediate interventions (oxygen, nitroglycerin) take priority before an invasive procedure. Request a prescription for an increase in statin medication: Adjusting statins is a long-term strategy; it does not address the acute issue of chest pain and shortness of breath. Step 2: Request a prescription for a beta-blocker: Beta-blockers reduce heart rate and myocardial oxygen demand, but nitroglycerin provides more immediate relief for chest pain. Check a STAT cardiac troponin: A repeat troponin may be necessary, but the initial focus is on stabilizing the client’s oxygenation and relieving chest pain.
