What is the primary intervention for a client with an acute myocardial infarction?

Correct Answer: A

Rationale: The correct answer is A: Administer aspirin. Aspirin helps prevent further clot formation by inhibiting platelet aggregation, reducing the risk of additional heart damage. It is a standard treatment in acute myocardial infarction. Administering morphine (B) may be considered for pain relief but is not the primary intervention. Monitoring vital signs (C) is important, but not the primary intervention. Administering fibrinolytics (D) is indicated in certain cases but is not the primary intervention and requires specific criteria and caution.

Correct Answer: B

Rationale: The correct answer is B: Encourage fluid intake. Adequate hydration helps in pain management by promoting circulation and reducing inflammation. Opioids (choice A) should only be used if non-pharmacological interventions fail. Administering oxygen (choice C) is not typically indicated for pain management. Monitoring electrolyte levels (choice D) is important but not the most immediate intervention for acute pain post-surgery.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. In ARDS, the primary issue is hypoxemia due to impaired gas exchange in the lungs. Administering oxygen helps to increase the oxygen levels in the blood, improving oxygenation to vital organs. Corticosteroids (B) are not indicated as they have not shown consistent benefit in ARDS treatment. Bronchodilators (C) are not effective as ARDS is not primarily a bronchoconstrictive disorder. Applying an ice pack to the chest (D) is not relevant and will not address the underlying hypoxemia. Administering oxygen is the most effective and essential intervention to correct hypoxemia in ARDS.

Correct Answer: A

Rationale: The correct answer is A: Administer nitroglycerin. This is the priority intervention because nitroglycerin helps dilate blood vessels, reducing chest pain in clients with heart disease. It improves blood flow to the heart, relieving ischemia. Morphine (B) can mask symptoms and should be used if pain persists after nitroglycerin. Beta blockers (C) are beneficial in chronic management but not for immediate relief. Aspirin (D) helps prevent clot formation but is not the priority in acute chest pain.

Correct Answer: A

Rationale: The correct answer is A - Administer IV fluids. This is the priority intervention for a client with suspected hypovolemia and hypotension as it helps to restore intravascular volume and improve blood pressure. IV fluids will address the underlying cause of hypotension by increasing circulating volume. Monitoring blood pressure (B) is important but administering IV fluids takes precedence. Administering corticosteroids (C) is not indicated for hypovolemia and hypotension. Administering oxygen (D) may be necessary if there is evidence of hypoxia, but addressing fluid volume status is the primary concern in this scenario.
