The nurse is caring for a client during a cardiac arrest. The monitor displays the rhythm below. Which intervention should the nurse perform at this time?

Administer amiodarone 200 mg IV push

Defibrillate the client using 200 joules

CPR until the physician stops the code

Administer adenosine 12 mg IV push

Answer and Explanation

The Correct Answer is C

A. Administer amiodarone 200 mg IV push: Amiodarone is used for shockable rhythms like ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) that are refractory to defibrillation. The rhythm on the monitor is asystole, which is non-shockable, and amiodarone is not indicated here.

B. Defibrillate the client using 200 joules: Defibrillation is only appropriate for shockable rhythms such as VF or pulseless VT. Asystole is not shockable, and defibrillation in this rhythm would be ineffective and inappropriate.

C. CPR until the physician stops the code: The rhythm strip shows asystole, a flatline with no electrical activity. The priority intervention is to initiate and continue high-quality cardiopulmonary resuscitation (CPR) immediately and continue until the code is terminated by the physician. This is consistent with Advanced Cardiac Life Support (ACLS) guidelines.

D. Administer adenosine 12 mg IV push: Adenosine is used to terminate supraventricular tachycardia (SVT) and is not indicated in asystole or during cardiac arrest. It would have no effect in a rhythm with no electrical activity.

Correct Answer is ["2.5"]

Explanation

Convert the available dose from grams (Gm) to milligrams (mg):

0.15 Gm × 1000 mg/Gm = 150 mg

Desired dose = 75 mg

Available dose = 150 mg

Volume = 5 mL

Formula:

Volume to administer = Desired dose / Available dose × Volume

= 75 mg / 150 mg × 5 mL

= 0.5 × 5 mL

Volume to administer = 2.5 mL

A. Dehydration B. Infection C. Renal insufficiency D. internal bleeding

Correct Answer is A

Explanation

A. Dehydration: The elevated hemoglobin (17 g/dL) and hematocrit (54%), along with an increased BUN (28 mg/dL) and normal creatinine, suggest hemoconcentration, a key indicator of dehydration. Small bowel obstruction often leads to fluid loss through vomiting and third spacing into the bowel, contributing to this condition.

B. Infection: The WBC count is normal at 8.5, which does not support an active infection. Infections typically result in leukocytosis (WBC >10.5), especially in acute abdominal conditions.

C. Renal insufficiency: Although BUN is elevated, creatinine remains normal (1.1 mg/dL). This pattern, particularly with hemoconcentration, supports pre-renal azotemia due to dehydration, not intrinsic renal insufficiency.

D. Internal bleeding: Internal bleeding typically causes a decrease in hemoglobin and hematocrit due to blood loss. The elevated values in this case rule out active bleeding and instead indicate fluid volume deficit.
