A nurse is caring for a patient who has a suspected myocardial infarction. Which of the following should the nurse administer first?
Nitroglycerin
Aspirin
Morphine
Oxygen
The Correct Answer is D
A. Nitroglycerin: Nitroglycerin is used to relieve chest pain by dilating coronary arteries and increasing blood flow. However, in the immediate setting of a suspected MI, oxygen is prioritized to ensure adequate oxygenation.
B. Aspirin: Aspirin is essential in the early treatment of MI to prevent further clot formation by inhibiting platelet aggregation, but oxygen would still come first if the client’s oxygenation is compromised.
C. Morphine: Morphine is used for pain relief and to reduce anxiety and oxygen demand on the heart. However, it is administered after ensuring oxygen supply.
D. Oxygen: Oxygen should be administered first in a suspected myocardial infarction to ensure the heart and tissues receive adequate oxygen, especially if the patient is hypoxic.

Correct Answer is B
Explanation
A. Keep the affected knee flexed. Flexing the knee for prolonged periods can impede venous return and increase the risk of thrombosis. The knee should be extended, not flexed.
B. Encourage increased fluid intake. Encouraging fluid intake helps to prevent dehydration, which is a risk factor for blood clot formation. Adequate hydration helps keep the blood less viscous and reduces the risk of DVT.
C. Massage the client's calf on the affected side. Massaging the calf could dislodge a clot if one is present, leading to serious complications such as a pulmonary embolism. This is contraindicated.
D. Promote bed rest for 5-10 days. Early ambulation and movement are key to preventing DVT after surgery. Prolonged bed rest increases the risk of DVT due to venous stasis.
