Which of the following clinical manifestations would make the nurse suspect the client is experiencing a myocardial infarction (MI)?

A. Nausea and vomiting.

Radiating pain to the left arm.

Shortness of breath.

Headache.

Answer and Explanation

The Correct Answer is B

Choice B rationale

Radiating pain to the left arm is a classic symptom of a myocardial infarction (MI). This pain occurs due to the heart muscle not receiving enough oxygen, often because of a blockage in one or more coronary arteries. The pain can radiate to the left arm, jaw, neck, or back, and is a key indicator for diagnosing an MI.

Choice A rationale

Nausea and vomiting can occur during an MI but are not the most distinctive symptoms for diagnosis. They can also be associated with other conditions, making them less specific indicators of MI.

Choice C rationale

Shortness of breath is a common symptom during an MI, resulting from reduced oxygen supply to the heart. However, while it is an important clinical manifestation, it can also be associated with other cardiac or respiratory conditions.

Choice D rationale

Headache is not a typical symptom of an MI. It is less commonly associated with heart attacks and can be caused by a wide range of other factors, making it an unreliable symptom for diagnosing MI.

Correct Answer is ["D","E"]

Explanation

Choice D rationale

Administering aspirin 325 orally is important for clients with a myocardial infarction (MI). Aspirin helps to inhibit platelet aggregation, reducing the risk of further clot formation and improving blood flow to the heart. This can significantly decrease mortality and complications associated with MI.

Choice E rationale

Applying oxygen via nasal cannula helps to increase oxygen delivery to the heart and other vital organs during an MI. Ensuring adequate oxygenation can help reduce the extent of myocardial injury and support overall cardiac function during a critical period.

Choice A rationale

Placing the client in a supine position is not appropriate during an MI, as it can increase discomfort and the workload on the heart. Instead, the client should be positioned in a semi-Fowler’s or comfortable position to improve breathing and comfort.

Choice B rationale

Administering morphine intramuscularly is not recommended during an MI. Morphine can be used for pain relief but should be given intravenously to ensure rapid onset and better control over dosing. Intramuscular administration is less effective and can delay pain relief.

Choice C rationale

Administering nitroglycerin subcutaneously is not appropriate. Nitroglycerin is typically given sublingually or intravenously during an MI to provide rapid vasodilation and pain relief. Subcutaneous administration is not effective in this context. .

A. Administer a laxative to cleanse the bowel before the CT scan. B. Administer the biguanide medication as scheduled. C. Advise the client to fast for 24 hours before the CT scan. D. Ensure the client is adequately hydrated before the CT scan.

Correct Answer is D

Explanation

Choice A rationale

Administering a laxative is not necessary for a CT scan of the abdomen with contrast. Laxatives are typically used for bowel preparation for procedures like colonoscopies.

Choice B rationale

Biguanide medications such as metformin should be held before and after the administration of contrast medium to prevent lactic acidosis, particularly in clients with liver disease.

Choice C rationale

Fasting for 24 hours is not required before a CT scan with contrast medium. Typically, clients are asked to fast for a few hours prior to the procedure.

Choice D rationale

Ensuring the client is adequately hydrated helps to protect kidney function and reduce the risk of contrast-induced nephropathy. Hydration is especially important for clients with a history of liver disease.
