A patient with a cardiac disorder is having increased premature ventricular contractions and feels "anxious" and short of breath. After vital signs are obtained, what actions should the nurse take? Select all that apply.
Notify the health-care provider.
Start oxygen at 2 L/min.
Order an electrocardiogram and cardiac enzymes.
Place bed in modified Trendelenburg position.
Allow the patient to rest alone.
Elevate the head of the bed.
Correct Answer : A,B,C,F
A. Increased premature ventricular contractions along with symptoms of anxiety and shortness of breath may indicate worsening cardiac function or an acute cardiac event, necessitating immediate medical attention.
B. Oxygen therapy may help alleviate symptoms of shortness of breath and improve oxygenation in patients experiencing cardiac symptoms.
C. These diagnostic tests can provide valuable information about cardiac function and any potential myocardial damage or ischemia, helping guide further treatment and management.
D. The modified Trendelenburg position may increase cardiac workload, which is not beneficial in the case of PVCs.
E. The patient should not be left alone due to the need for ongoing assessment and potential rapid intervention. Furthermore, leaving them alone could worsen their anxiety.
F. Elevating the head of the bed can aid in breathing and comfort, reducing the sensation of breathlessness.

Correct Answer is A
Explanation
A. The P wave on an ECG represents atrial depolarization, which occurs as the electrical impulse originates in the sinoatrial (SA) node and spreads through the atria, initiating atrial contraction.
B. Atrial repolarization typically occurs during the QRS complex and is not represented by the P wave. Atrial repolarization is masked by the larger QRS complex.
C. Ventricular depolarization is represented by the QRS complex on an ECG, as the electrical impulse spreads through the ventricles, leading to ventricular contraction.
D. Ventricular repolarization typically occurs during the T wave and is not represented by the P wave. Ventricular repolarization involves the recovery of ventricular muscle cells after contraction.
Correct Answer is ["A","C","D","E"]
Explanation
A. The primary function of the kidneys is to filter blood and eliminate waste products as urine.
B. Vitamin B12 activation primarily occurs in the liver, not the kidneys.
C. The kidneys help regulate the body's acid-base balance by excreting or conserving bicarbonate ions and hydrogen ions.
D. The kidneys produce erythropoietin, a hormone that stimulates the production of red blood cells in the bone marrow.
E. The kidneys play a key role in regulating blood pressure by adjusting the volume of blood and the balance of electrolytes in the body. They also produce hormones such as renin, which helps regulate blood pressure.
