A nurse is collecting data from a client prior to administering metoprolol. For which of the following findings should the nurse withhold the medication?

A. Ferrous sulfate: Ferrous sulfate is an iron supplement used to treat or prevent low blood levels of iron (such as those caused by anemia or pregnancy). It is not used to treat high INR levels.

B. Heparin: Heparin is an anticoagulant, or blood thinner, that prevents the formation of blood clots. It would not be used to treat a high INR level, as it could potentially increase the INR even further.

C. Prednisone: Prednisone is a corticosteroid that reduces inflammation in the body. It is not used to treat high INR levels.

D. Vitamin K: This is correct. Vitamin K is used to help blood clot and is given to patients who have a high INR level to reduce the risk of bleeding. Warfarin works by blocking the effects of vitamin K, so giving vitamin K can help reverse the effects of warfarin and lower the INR.

A. Headache:

Headache is not typically a clinical manifestation of an acute myocardial infarction. The more common symptoms are related to chest pain, autonomic responses, and cardiovascular changes.

B. Tachycardia:

Tachycardia, or an increased heart rate, is a common symptom during an acute MI. This occurs as the body attempts to compensate for decreased cardiac output and perfusion.

C. Nausea:

Nausea is a frequent symptom associated with an acute MI. It results from the activation of the autonomic nervous system during the heart attack.

D. Diaphoresis:

Diaphoresis, or excessive sweating, is a classic symptom of an acute MI. It occurs due to the sympathetic nervous system's response to pain and stress from the heart attack.

E. Orthopnea:

Orthopnea, or difficulty breathing when lying down, is more commonly associated with congestive heart failure rather than an acute MI. While shortness of breath can occur during an MI, orthopnea is not a primary manifestation.
