NCLEX RN Test Bank with Rationales Questions
Extract:
Question 1 of 5
The nurse notes that the client's continuous electrocardiogram (ECG) complexes are very small and hard to evaluate. Which setting on the ECG monitor console should the nurse check?
Correct Answer: D
Rationale: The amplitude, commonly called 'gain,' regulates the size of the complex and can be adjusted up and down to some degree. The power button turns the machine on and off. The low and high alarm settings indicate the heart rate limits beyond which an alarm will sound.
Question 2 of 5
A client taking clozapine (Clozaril) states, 'I think I'm getting the flu. I have a fever and feel weak.' Which of the following should the nurse do next?
Correct Answer: D
Rationale: Fever and weakness in a client taking clozapine may indicate agranulocytosis, a serious side effect, requiring immediate physician notification after confirming the temperature.
Question 3 of 5
A client returns to the recovery room following left supratentorial surgery for treatment of a brain tumor. The nurse should place the client in which position to facilitate venous drainage?
Correct Answer: C
Rationale: The head of the bed should be elevated 30 degrees to promote venous drainage and decrease intracranial pressure. The client's head should be in a midline, or neutral, position. Clients with supratentorial surgery should be positioned on the nonoperative side to prevent displacement of the cranial contents by gravity.
Question 4 of 5
The nurse monitors the serum electrolyte levels of a client who is taking digoxin (Lanoxin). Which of the following electrolyte imbalances is a common cause of digoxin toxicity?
Correct Answer: D
Rationale: Hypokalemia enhances digoxin's effect on the heart, increasing toxicity risk by altering cardiac membrane potential.
Question 5 of 5
When teaching a group of parents about the potential for febrile seizures in children, which of the following facts should the nurse include?
Correct Answer: B
Rationale: Febrile seizures typically occur as the fever rises rapidly in young children (usually under age 5), not specifically after immunizations or in older children.
