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

Answer and Explanation

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 ["A","B","C","E"]

Explanation

A. Assist with ordered exercise as needed: Mobility and exercises such as ankle pumps help promote circulation and prevent venous stasis, reducing the risk of DVT.

B. Encourage fluids: Encouraging fluids helps prevent dehydration, which reduces blood viscosity and lowers the risk of clot formation.

C. Measure affected limb circumference: Measuring limb circumference is important for detecting early signs of DVT, such as swelling in the affected limb.

D. Massage calves and thighs: Massaging the legs is contraindicated in clients at risk for DVT as it can dislodge a clot, leading to a pulmonary embolism.

E. Apply compression stockings: Compression stockings promote venous return and reduce the risk of blood pooling in the lower extremities, thus preventing DVT.
