Certified Pediatric Nurse Exam Practice Questions Questions
Question 1 of 5
Which of the following responses indicates sympathetic nervous system function?
Correct Answer: A
Rationale: The sympathetic nervous system is responsible for the body's "fight or flight" response. Tachycardia (increased heart rate) and dilated pupils are classic responses of the sympathetic nervous system activation during times of stress or danger. These physiological responses prepare the body for action, such as running away from a threat.
Question 2 of 5
while planning therapeutic care for type ï‰ diabetes mellitus you would expect treatment plan to include:
Correct Answer: D
Rationale: Type 1 diabetes mellitus is characterized by the body's inability to produce insulin. Therefore, the mainstay of treatment for type 1 diabetes is insulin therapy. Insulin injections are necessary to replace the insulin that the body is unable to produce on its own. While physical exercise and dietary management are important components of managing diabetes, in the case of type 1 diabetes, insulin is an essential part of the treatment plan to control blood glucose levels effectively and prevent complications. Oral hypoglycemic agents, on the other hand, are typically used in the treatment of type 2 diabetes, where the body's insulin production may be insufficient or ineffective.
Question 3 of 5
If a patient has severe hyperkalemia, it is possible to administer calcium gluconate intravenously to:
Correct Answer: D
Rationale: Calcium gluconate is administered intravenously in the setting of severe hyperkalemia to antagonize the effects of potassium on the heart. Hyperkalemia can lead to dangerous cardiac arrhythmias due to the changes in membrane potential of cardiac cells caused by increased extracellular potassium levels. Administration of calcium gluconate helps stabilize the cardiac cell membrane potential, protecting against the risk of life-threatening arrhythmias. It doesn't provide an immediate decrease in serum potassium levels (Choice A) or prevent transient renal failure (TRF) (Choice B). Therefore, the correct answer is D, as calcium gluconate primarily acts to counteract the effects of hyperkalemia on the heart.
Question 4 of 5
For which of the ff conditions would the use of salt tablets be considered?
Correct Answer: A
Rationale: Salt tablets should be considered for mild deficits of serum sodium. Salt tablets contain sodium chloride, which helps increase the sodium levels in the body. In cases of mild deficits of serum sodium, also known as hyponatremia, salt tablets can help replenish the sodium levels and correct the electrolyte imbalance. However, for severe deficits of serum magnesium, potassium, or calcium, other specific electrolyte replacement therapies are usually preferred over salt tablets. It is important to consult a healthcare professional for proper diagnosis and treatment of electrolyte imbalances.
Question 5 of 5
In preparing a preschool-aged patient for an injection, the most appropriate nursing intervention is to:
Correct Answer: A
Rationale: Allowing the child to practice on a doll can help reduce anxiety and prepare them for the procedure.
