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 A

Explanation

A. This question assesses the client's level of orthopnea, which is a condition where the client experiences difficulty breathing when lying flat. People with heart failure may need to use multiple pillows to prop themselves up to breathe more easily at night, making it an important question to assess respiratory status.
B. Chest pain with exertion can be indicative of cardiovascular issues but this question does not directly assess the client's respiratory status.
C. Tight rings and shoes can indicate fluid retention and edema, but it does not provide specific information about respiratory status.
D. Frequent nighttime voiding (nocturia) is common in heart failure, but it relates more to kidney function and fluid retention rather than respiratory function.

A. weigh daily on the same scale at the same time of day B. restrict foods that are high in potassium. C. engage in aerobic activity for one hour each day. D. monitor sugar intake

Correct Answer is A

Explanation

A. Weigh daily on the same scale at the same time of day - Daily weight measurement is critical for clients with heart failure to monitor for fluid retention, which can indicate worsening heart failure.
B. Restrict foods that are high in potassium - This is not recommended unless the client is on certain medications (e.g., potassium-sparing diuretics) that cause high potassium levels. Generally, potassium- rich foods are beneficial for heart health.
C. Engage in aerobic activity for one hour each day - Although exercise is important, the intensity and duration should be individualized, and clients with heart failure may need to start with lower-intensity activity.
D. Monitor sugar intake - While important for diabetes management, monitoring sugar intake is not a primary focus for clients with heart failure unless they also have diabetes.
