1. A child with pertussis is receiving azithromycin (Zithromax Injection) IV. Which intervention is most important for the nurse to include in the child's plan of care?
- A. Obtain vital signs to monitor for fluid overload
- B. Change IV site dressing every 3 days and as needed
- C. Monitor for signs of facial swelling or urticaria
- D. Assess for abdominal pain and vomiting
Correct answer: C
Rationale: When administering azithromycin IV, monitoring for signs of an allergic reaction, such as facial swelling or urticaria, is crucial. This helps in early detection of potential adverse reactions and ensures prompt intervention to prevent complications associated with the medication. The other options are not directly related to the administration of azithromycin IV in this scenario. Monitoring for fluid overload would be more relevant for fluid administration, changing IV site dressing is important but not the priority in this case, and assessing for abdominal pain and vomiting may be important but not as critical as monitoring for signs of an allergic reaction.
2. A 2-year-old child with heart failure (HF) is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?
- A. Determine the pulse deficit.
- B. Administer the scheduled dose.
- C. Calculate the safe dose range.
- D. Review the serum digoxin level.
Correct answer: B
Rationale: Administering the scheduled dose is appropriate in this scenario. The nurse obtained an apical heart rate of 128 bpm, which is within the expected range for a 2-year-old child. Therefore, there is no immediate concern to withhold the scheduled dose of digoxin. Determining the pulse deficit is not necessary as the heart rate is appropriate. Calculating the safe dose range is not needed as the current dose is within the therapeutic range. Reviewing the serum digoxin level may be indicated later for monitoring but is not urgent based on the heart rate assessment. Administering the scheduled dose of digoxin is the correct action at this time.
3. What is the recommended analgesia for preparing a school-age child for a lumbar puncture (LP)?
- A. Ondansetron (Zofran) 4 mg / 5 ml PO TID.
- B. Codeine 10 mg PO 30 minutes before the procedure.
- C. A transdermal fentanyl (Duragesic) patch immediately before the procedure.
- D. EMLA (eutectic mixtures of local anesthetics) 2.5 hours before the procedure.
Correct answer: D
Rationale: For a lumbar puncture in a school-age child, EMLA cream should be applied 2.5 hours before the procedure. EMLA is commonly used to numb the skin, reducing pain and discomfort for the child during the procedure. Choices A, B, and C are incorrect because ondansetron is an antiemetic, codeine is an opioid analgesic that may not be suitable for children, and transdermal fentanyl is a strong opioid that is not typically used for local anesthesia in children undergoing lumbar puncture.
4. A school-age child with a history of type 1 diabetes mellitus is brought to the emergency department with confusion and rapid breathing. The practical nurse (PN) suspects diabetic ketoacidosis (DKA). Which initial intervention should the PN anticipate?
- A. Administer subcutaneous insulin.
- B. Give oral glucose tablets.
- C. Start intravenous fluids.
- D. Administer oxygen therapy.
Correct answer: C
Rationale: Intravenous fluids are typically the initial intervention in diabetic ketoacidosis (DKA) to treat dehydration and stabilize the patient's condition. The fluid replacement helps correct electrolyte imbalances and improve perfusion, which are crucial in managing DKA. Insulin therapy follows after fluid resuscitation to address the underlying cause of DKA, which is the lack of insulin leading to increased ketone production. Administering subcutaneous insulin (Choice A) would be premature without first addressing the dehydration and electrolyte imbalances. Giving oral glucose tablets (Choice B) is contraindicated in DKA as the patient already has high blood glucose levels. Administering oxygen therapy (Choice D) may be necessary based on the patient's condition, but addressing dehydration with intravenous fluids is the priority intervention in DKA.
5. A 2-year-old child is admitted with severe dehydration due to gastroenteritis. Which assessment finding indicates that the child's condition is improving?
- A. Decreased heart rate.
- B. Sunken fontanelle.
- C. Increased urine output.
- D. Dry mucous membranes.
Correct answer: C
Rationale: Increased urine output is a positive sign indicating that the child's hydration status is improving. It suggests that the kidneys are functioning more effectively and able to excrete urine, which is a crucial indicator of improved hydration levels in a dehydrated patient. Decreased heart rate (Choice A) can be a sign of possible shock. A sunken fontanelle (Choice B) is a sign of dehydration. Dry mucous membranes (Choice D) are also indicative of dehydration.
