Pediatric CCRN Practice Questions Questions
Question 1 of 5
Marichu is admitted to the hospital because of hepatic failure and was prescribed with lactulose (Duphalac). The primary action of this drug is:
Correct Answer: B
Rationale: Lactulose (Duphalac) is a synthetic sugar that is not absorbed in the small intestine but is broken down by bacteria in the colon into short-chain fatty acids and low molecular weight organic acids. The primary action of lactulose is to decrease resident intestinal flora. This reduces the production of ammonia in the colon and leads to acidification of the colonic contents. By doing so, lactulose helps in treating hepatic encephalopathy, a condition associated with hepatic failure where ammonia levels are elevated in the body. It works by promoting the excretion of ammonia through the stool, thereby reducing the toxic effects of ammonia on the brain.
Question 2 of 5
A client who was diagnosed with type I diabetes mellitus 14 years ago is admitted to the medical-surgical unit with abdominal pain. On admission, the client's blood glucose level is 470 mg/dl. Which finding is most likely to accompany this blood glucose level?
Correct Answer: B
Rationale: A blood glucose level of 470 mg/dl indicates severe hyperglycemia in a client with type I diabetes mellitus. Arm and leg trembling, known as tremors, is a common symptom associated with high blood glucose levels. Tremors are often a result of the body's stress response to the extreme levels of glucose in the blood. Other common symptoms of hyperglycemia include increased thirst, frequent urination, blurred vision, and fatigue. Cool, moist skin, rapid, thready pulse, and slow, shallow respirations are not typically associated with hyperglycemia and are more indicative of other conditions or clinical situations.
Question 3 of 5
A client is being returned to the room after a subtotal thyroidectomy. Which piece of equipment is most important for the nurse to keep at the client's bedside?
Correct Answer: C
Rationale: Following a subtotal thyroidectomy, there is a risk of airway compromise and difficulty breathing due to the close proximity of the surgical site to the trachea. In case of swelling or other complications leading to airway obstruction, having a tracheostomy set readily available at the client's bedside is crucial for quick and efficient management of any respiratory distress. This equipment allows the healthcare team to establish a secure airway if needed, ensuring the client's safety and minimizing the risk of respiratory compromise post-operatively. The other equipment choices are important but having a tracheostomy set is the most critical for this particular situation to address potential airway issues promptly.
Question 4 of 5
The nurse knows which of the following is true about immunity?
Correct Answer: C
Rationale: Antibodies, also known as immunoglobulins, are proteins produced by a type of white blood cell called B-lymphocytes (B-cells). These antibodies play a crucial role in the immune response by recognizing and binding to specific antigens such as pathogens. This binding can lead to the inactivation of the pathogens or marking them for destruction by other immune cells. B-cells are a key component of the humoral immune response, which involves the production of antibodies to defend against infections. The statement that antibodies are produced by the B-cells is, therefore, true.
Question 5 of 5
When caring for Mr. Reyes, the nurse should assess for
Correct Answer: B
Rationale: When caring for Mr. Reyes, the nurse should assess for an altered level of consciousness as it is a crucial indicator of his overall neurological status. Changes in consciousness can signify multiple underlying issues such as neurological, metabolic, or circulatory problems. It is important for the nurse to monitor Mr. Reyes closely for any signs of confusion, disorientation, agitation, drowsiness, or changes in behavior that could indicate a decline in his neurological function. Assessing and addressing alterations in consciousness promptly is essential for providing appropriate care and preventing further complications.
