A client admitted to the Emergency Department (ED) and the cardiac monitor shows multifocal premature ventricular contractions (PVC's). Initial laboratory findings are as follows. The nurse recognizes that the client's PVC's are most likely caused by:

hypermagnesemia.

hypocalcemia.

hypokalemia,

hyperglycemia

Answer and Explanation

The Correct Answer is C

A.   Hypermagnesemia can cause bradycardia and hypotension, but it is less commonly associated with PVCs. This does not align with the lab results provided.
B.   Hypocalcemia can cause arrhythmias, but it is not the most likely cause of PVCs in this case, considering other findings.
C.   Hypokalemia (low potassium) is a known cause of PVCs. The patient's potassium level is 2.8 mEq/L, which is significantly low and most likely contributing to the PVCs.
D.   Although hyperglycemia can affect cardiac function, it is less commonly linked to PVCs compared to electrolyte imbalances, such as hypokalemia.

Correct Answer is C

Explanation

A. These are not typical symptoms of atrial flutter. They may be seen in other conditions like hypertensive crisis or systemic problems, but not as a primary manifestation of atrial flutter.
B. These are classic signs of diabetes or hyperglycemia, not atrial flutter.
C. These are common symptoms of atrial flutter, which results in an irregular heart rhythm and may cause increased heart rate, leading to palpitations and shortness of breath.
D. A systolic murmur is more associated with valve problems, and anxiety could be a result of various issues but is not a typical finding directly caused by atrial flutter.

A. Petechiae B. Diarrhea C. Intractable vomiting D. Urinary incontinence

Correct Answer is A

Explanation

A. Petechiae (small, pinpoint hemorrhages) are a common manifestation of DIC due to the excessive clotting and subsequent breakdown of clotting factors, leading to bleeding into the skin.
B. Diarrhea is not typically a primary symptom of DIC, although gastrointestinal bleeding can occur in severe cases.
C. Intractable vomiting is not characteristic of DIC, although it could occur in clients with severe bleeding or complications.
D. Urinary incontinence is not a direct manifestation of DIC, although it could occur secondary to neurological or other systemic complications.
