The nurse responds to a call for assistance with a patient in pulseless ventricular tachycardia. The nurse prepares for what first-line treatment for this rhythm?

A. While renal calculi (kidney stones) can cause renal issues, they are not directly related to diminished renal output in this scenario. Hypovolemia, or low blood volume, is more pertinent to the patient's presentation of scant voiding and inability to eat or drink.
B. Diminished renal output, as evidenced by scant voiding, can be indicative of hypovolemia. Hypovolemia reduces kidney perfusion, leading to decreased urine output as the kidneys conserve fluid.
C. While inactivity can contribute to various health issues, it's not directly related to diminished renal output in this case. The primary concern is addressing the immediate physiological impact of decreased renal function.

D. While nephrotoxic drugs can impair renal function, there's no indication in the scenario that the patient has been exposed to such drugs. Thus, they are not directly relevant to the current situation.

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.
