The nurse is caring for a child with acute renal failure. Which clinical manifestation should the nurse recognize as a sign of hyperkalemia?
Cardiac arrhythmia
Seizure
Dyspnea
Oliguria
The Correct Answer is A
Choice A reason:
Cardiac arrhythmia is a primary clinical manifestation of hyperkalemia. Hyperkalemia, defined as an elevated level of potassium in the blood, can significantly affect the electrical activity of the heart. This can lead to various types of arrhythmias, including bradycardia, ventricular tachycardia, and even cardiac arrest1. The presence of arrhythmias is a critical indicator of hyperkalemia and requires immediate medical attention to prevent life-threatening complications.
Choice B reason:
Seizures are not typically associated with hyperkalemia2. While severe electrolyte imbalances can potentially lead to neurological symptoms, seizures are more commonly linked to conditions such as hyponatremia (low sodium levels) or hypocalcemia (low calcium levels). Therefore, seizures are not a primary sign of hyperkalemia.
Choice C reason:
Dyspnea, or difficulty breathing, can occur in various medical conditions, including heart failure and respiratory disorders. While hyperkalemia can lead to muscle weakness and fatigue, which might indirectly affect breathing, dyspnea is not a primary clinical manifestation of hyperkalemia. The main concern with hyperkalemia is its effect on cardiac function.
Choice D reason:
Oliguria, or reduced urine output, is a symptom of acute renal failure but not specifically indicative of hyperkalemia. While acute renal failure can lead to hyperkalemia due to the kidneys’ inability to excrete potassium, oliguria itself is not a direct sign of hyperkalemia. The focus should be on the cardiac effects of elevated potassium levels

Correct Answer is D
Explanation
Choice A reason:
Releasing traction every hour to perform skin care: Releasing traction every hour is not recommended as it can disrupt the alignment and healing process of the fractured femur. Skin care is important, but it should be performed without compromising the traction setup.
Choice B Reason:
Releasing traction once every 8 hours to check circulation: While checking circulation is crucial, releasing traction every 8 hours is not necessary and can interfere with the therapeutic benefits of traction. Circulation can be monitored without releasing the traction.
Choice C Reason:
Maintaining continuous traction until 1 hour before the scheduled surgery: Continuous traction is essential to maintain the alignment of the fractured femur. However, there is no need to release traction 1 hour before surgery unless specifically instructed by the surgical team.
Choice D Reason:
Maintaining continuous traction and checking the position of traction: This is the most appropriate action. Continuous traction ensures proper alignment and healing of the fractured femur. Regularly checking the position of traction helps prevent complications and ensures the effectiveness of the treatment.
Correct Answer is A
Explanation
Choice A reason:
Oral rehydration solution (ORS) is the first-line treatment for children with acute diarrhea and moderate dehydration. ORS contains a precise balance of electrolytes and glucose, which helps to rehydrate the child effectively by promoting the absorption of water and electrolytes in the intestines. The World Health Organization (WHO) and the American Academy of Pediatrics recommend ORS as the preferred treatment for dehydration caused by diarrhea. It is effective, easy to administer, and can be given at home or in a healthcare setting.
Choice B reason:
Antidiarrheal medications such as paregoric are not recommended for children with acute diarrhea. These medications can slow down the movement of the intestines, which may prolong the infection and increase the risk of complications. Additionally, they do not address the underlying cause of dehydration. The primary goal in managing acute diarrhea is to rehydrate the child, which is best achieved with ORS.
Choice C reason:
Clear liquids, such as water, broth, or diluted fruit juices, can be used to provide some hydration, but they do not contain the necessary electrolytes to effectively treat moderate dehydration. Clear liquids alone are not sufficient to replace the lost electrolytes and fluids caused by diarrhea. ORS is specifically formulated to address these needs and is more effective in rehydrating the child.
Choice D reason:
Adsorbents, such as kaolin and pectin, are not recommended for the treatment of acute diarrhea in children. These substances can bind to the contents of the intestines and may reduce the frequency of stools, but they do not address the underlying dehydration. The primary focus should be on rehydration with ORS, which provides the necessary electrolytes and fluids to restore the child’s hydration status.
