NCLEX RN Predictor Exam Questions

Extract:


Question 1 of 5

When printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?

Correct Answer: C

Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading.
Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue.
Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first.
Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.
