Helen’s vital signs show a heart rate of 82 bpm, BP of 118/78 mm Hg, respiratory rate of 28 breaths per minute, and oxygen saturation of 93%. At the current time, what medication options may be selected for Helen? She continues to complain of heaviness in her chest. Select all that apply.

In Helen's case, with her symptoms suggesting possible chest pain and considering her vital signs, the following medication options could be appropriate:

1. **Oxygen**: Given that her oxygen saturation is at 93%, supplemental oxygen may be administered to ensure adequate oxygenation, especially if she is experiencing chest heaviness.

2. **Aspirin**: Aspirin is commonly used as an antiplatelet agent, especially in cases of suspected myocardial ischemia or acute coronary syndrome, to prevent further clot formation.

3. **IV Nitrates**: IV nitrates can help relieve chest pain and reduce cardiac workload by dilating coronary vessels, which may be beneficial if Helen’s chest heaviness is related to ischemia.

4. **Morphine**: Morphine can be used for pain relief and may also help reduce anxiety and decrease workload on the heart.

5. **Beta-adrenergic blockers**: These are often used to manage hypertension and angina, but their use should be carefully considered based on her overall clinical picture, including the presence of chest pain and possible underlying cardiac conditions.

**Summary**: The appropriate medication options that may be selected for Helen, considering her symptoms and vital signs, are:
- Oxygen
- Aspirin
- IV nitrates
- Morphine

The use of beta-adrenergic blockers may depend on the specific clinical context and should be administered with caution. Always consult a physician for individualized treatment decisions.
