The nurse on the unit hears an alarm sound in the client's room. Arriving in the room, the client is unresponsive. pulseless and the nurse sees the flat rhythm on the monitor. What is the FIRST action by the nurse?

Choice A rationale: Nitroglycerin tablets are not typically taken with water. They are designed to dissolve under the tongue for quick absorption into the bloodstream6789.

Choice B rationale: It is not necessary to go to the hospital to take the medication. The medication can be taken at the onset of chest pain6789.

Choice C rationale: This is the correct instruction. At the onset of chest pain, the patient should lie or sit down and place one tablet under the tongue6789.

Choice D rationale: If one tablet does not relieve the pain in 5 minutes, a second tablet may be taken. If the pain continues for another 5 minutes, a third tablet may be used. If the patient still has chest pain after a total of 3 tablets, they should seek immediate medical attention6789.

So, the correct answer is C, after analysing all choices

The correct answer is choice D: Prepare to administer supplemental O2 via nasal cannula.

Choice A rationale:

Atropine is used to treat bradycardia (slow heart rate), not atrial flutter with a rapid heart rate. Administering Atropine in this scenario could potentially worsen the patient’s condition by increasing the heart rate further.

Choice B rationale:

While reassessing the patient’s blood pressure is important, it is not the most immediate action. The patient’s current blood pressure is stable (118/64), and the priority is addressing the low oxygen saturation and high respiratory rate, which indicates respiratory distress.

Choice C rationale:

Adenosine is used to treat certain types of supraventricular tachycardia by temporarily slowing the heart rate, but it is not the first-line treatment for atrial flutter. Additionally, the patient’s blood pressure is stable, and there is no indication of hemodynamic instability that would necessitate immediate rate control.

Choice D rationale:

The patient’s oxygen saturation is 90%, which is below the normal range, and they are tachypneic with a respiratory rate of 26 breaths per minute. The first action should be to administer supplemental oxygen to improve oxygenation and prevent hypoxemia-related complications. Oxygen therapy can help stabilize the patient’s condition and improve oxygen saturation levels.
