Question: 1
A pediatric patient with severe respiratory failure is receiving extracorporeal membrane oxygenation (ECMO) support. Which statement regarding ECMO is correct?
1. ECMO provides long-term mechanical ventilation support.
CMO is a temporary intervention to allow time for lung recovery. CMO can be safely discontinued without any weaning process.
wer: C
anation: The correct statement regarding ECMO is that it is a tempora vention to allow time for lung recovery. ECMO is a life support techn rovides both cardiac and respiratory support for patients with severe ratory or cardiac failure. It is used as a bridge to recovery, allowing th nt's lungs or heart to rest and heal. ECMO is not a long-term solution pically discontinued once the patient's condition improves and their o ns can adequately support their vital functions. Discontinuing ECMO res a careful weaning process, as abrupt removal can lead to significa odynamic instability and complications.
stion: 2
ECMO is primarily used for cardiac support in pediatric patients.

During the care of a critically ill child, the nurse is responsible for managing the child's temperature monitoring and regulation device. Which device is commonly used for this purpose?
1. Bair Hugger
2. Cooling blanket
3. Intravascular catheter
4. Nasopharyngeal temperature probe Answer: A
roviding controlled warming or cooling as needed. Cooling blankets a vascular catheters may also be used for temperature regulation in spec tions, but the Bair Hugger is the device specifically designed for this ose. Nasopharyngeal temperature probes can be used for temperature toring but do not provide active temperature regulation.

Explanation: The most commonly used artery for arterial catheter placement in critically ill adult patients is the radial artery. The radial artery is easily accessible at the wrist, and its superficial location makes it suitable for arterial catheterization. Additionally, the radial artery has collateral circulation, reducing the risk of limb ischemia in case of complications. While the femoral artery is another commonly used site for arterial catheterization, the radial
artery is preferred due to its lower risk of infection and improved patient comfort and mobility. The brachial artery and dorsalis pedis artery are less commonly used for arterial catheter placement in this population.

anation: The commonly used medication for continuous sedation in ally ill adult patients requiring mechanical ventilation is Propofol. ofol is a short-acting sedative-hypnotic agent that provides rapid and ble sedation, making it suitable for patients requiring mechanical lation. It has a quick onset of action and a short half-life, allowing for titration and adjustment of sedation levels. Other medications such as mine, Midazolam, and Dexmedetomidine may have different indicati re not typically used as the primary choice for continuous sedation in lation.

A neonate in the neonatal intensive care unit requires umbilical catheterization for vascular access. Which type of umbilical catheter is commonly used for this purpose?
1. Umbilical venous catheter (UVC)
2. Umbilical arterial catheter (UAC)
3. Umbilical venous-arterial catheter (UVA)
anation: The commonly used umbilical catheter for vascular access in ates is the umbilical venous catheter (UVC). The UVC is inserted int lical vein to provide venous access for medication administration, blo pling, and fluid resuscitation. It is a central venous catheter specificall gned for neonatal care.

Explanation: When managing a patient receiving continuous sedation, the nurse should prioritize assessing the respiratory rate and oxygen saturation. Continuous sedation can depress the respiratory drive and lead to respiratory complications such as hypoventilation or respiratory distress. Therefore, monitoring the patient's respiratory rate and oxygen saturation is crucial to ensure adequate ventilation and oxygenation. While maintaining blood pressure
within the target range, assessing sedation level, and monitoring urine output and renal function are important aspects of care, respiratory function takes priority due to the potential risks associated with respiratory compromise in sedated patients.

anation: The commonly used site for central venous pressure (CVP) eter placement in critically ill patients is the internal jugular vein. The nal jugular vein provides direct access to the superior vena cava and ri m, allowing for accurate measurement of central venous pressure. Wh ubclavian vein and femoral vein can also be used for CVP catheter ement, the internal jugular vein is often preferred due to its accessibilit
risk of infection, and ease of catheter manipulation. The antecubital typically used for CVP catheter placement.

anation: During the defibrillation procedure, the nurse should prioritiz ring proper electrode placement. Proper electrode placement is essenti
should anticipate the initiation of synchronized cardioversion. Synchronized cardioversion is the treatment of choice for unstable cardiac dysrhythmias, such as atrial fibrillation or ventricular tachycardia with a pulse. Adenosine is typically used for the treatment of supraventricular tachycardias, but it is not the first-line intervention for unstable rhythms or irregular rhythms. Placement of a temporary pacemaker may be considered if the patient develops bradycardia or heart block, but it may not be the immediate intervention in this situation.

The nurse should ensure that the defibrillation pads or paddles are placed correctly according to the recommended guidelines and that they have good skin contact. Administering a sedative medication may be necessary to minimize patient discomfort or anxiety, but ensuring proper electrode placement takes priority to maximize the success of defibrillation. Checking the patient's blood pressure and administering oxygen via nasal cannula are
important aspects of ongoing care but are not the priority during the defibrillation procedure.

User: Stas***** I spent a long time searching for the right study material and finally found killexams.com, where everyone was cooperative and ready to assist. The team provided me with an excellent practice test for my AACN-CCRN-K training, which helped me prepare well for the exam. I found their material to be pretty accurate and will definitely use their resources for future tests.

User: Norvina***** Preparing for the AACN-CCRN-K certification exam can be complicated. Nine out of ten individuals fail the exam without suitable guidance. Killexams AACN-CCRN-K practice tests are the solution to this problem. Their exam practice tests offer an easy way to pass the AACN-CCRN-K exam. I appreciate the hard work of the Killexams team.

User: Tatjana***** The Killexams.com practice tests are designed to provide the exam material with the right capabilities. Their practice tests are easy to understand and quick to prepare. The material is customized without being overwhelming or burdensome. The ILT ebook can be used in conjunction with their material to increase effectiveness. I highly recommend Killexams.com to my peers in the office and anyone looking for great answers to the aacn-ccrn-k exam. Thank you, Killexams.com.

User: Elaine***** Initially, I thought that good things come with time, but my patience wore thin, and I realized that I had to take a stand before it was too late. Since my work involved dealing with an AACN-CCRN-K client base, I decided to become an AACN-CCRN-K expert in the office. I tried the Killexams.com demo for AACN-CCRN-K, loved it, and purchased it. The test engine is excellent, and their study kit has made me the new AACN-CCRN-K manager.

User: Anna***** I missed several questions on my exam because I did not remember the answers given in the unit, but I still passed with a score of 43/50. I recommend using killexams.com Questions and Answers to study, as it was the key to my success. The questions on killexams.com were similar to those on the actual Nursing aacn-ccrn-k exam.
