Question 1 of 5.
The nurse is caring for a client with the following tracing on the electrocardiogram (ECG). It would be correct for the nurse to document this tracing as.
A. sinus bradycardia.
B. normal sinus rhythm with first degree block.
C. atrial flutter.
D. atrial fibrillation.
Explanation: Atrial fibrillation is characterized by an irregular rhythm and absent P waves, as described.
Question 2 of 5.
The nurse is caring for a client with the below tracing on the electrocardiogram (ECG). The nurse should anticipate which prescription from the primary healthcare provider (PHCP)?
A. captopril
B. atropine
C. adenosine
D. diltiazem
Explanation: Atropine is used to treat bradycardia, which may be indicated by certain ECG tracings showing slow heart rates. Captopril is an ACE inhibitor for hypertension or heart failure, adenosine is used for supraventricular tachycardia, and diltiazem is a calcium channel blocker for rate control in atrial arrhythmias.
Question 3 of 5.
What is the correct documentation of the patient's peripheral pulse when the finding is that the posterior tibial pulse is weak and thready?
A. Grade C posterior tibial pulse
B. Posterior tibial pulse is Grade B
C. The client's posterior tibial is 2
D. Posterior tibial pulse is 1
Explanation: A weak and thready pulse is documented as a 1+ on a 0-4 scale, where 1 indicates a barely palpable pulse.
Question 4 of 5.
The nurse is caring for a client who appears to be developing heart failure (HF). Which of the following laboratory tests would the nurse expect the primary health care provider (PHCP) to prescribe to confirm the diagnosis?
A. Basic metabolic panel (BMP)
B. B-type natriuretic peptide (BNP)
C. Lipid profile
D. Troponin
Explanation: BNP is a specific biomarker elevated in heart failure, reflecting ventricular stress and fluid overload.
Question 5 of 5.
The nurse is caring for a client with the following tracing on the electrocardiogram (ECG). The nurse identifies this tracing as
A. sinus tachycardia.
B. supraventricular tachycardia.
C. ventricular tachycardia.
D. atrial flutter.
Explanation: Ventricular tachycardia is a life-threatening arrhythmia requiring immediate intervention, characterized by wide QRS complexes on ECG.
