Question 1 of 5.
Which of the following actions should the nurse take for a client immediately postoperative following a coronary artery bypass graft surgery (CABG)? Select all that apply.
A. Obtain the client's capillary blood glucose
B. Provide tracheostomy care, as needed
C. Teach the client about the driving restrictions after this procedure
D. Ground the epicardial pacing wires to the pacemaker generator
E. Ensure patency of the mediastinal chest tubes
Explanation: Monitoring blood glucose is crucial, especially in clients with diabetes or stress-induced hyperglycemia post-CABG. B: Incorrect - Tracheostomy care is not typically required unless the client has a tracheostomy, which is not indicated here. C: Incorrect - Teaching about driving restrictions is important but not an immediate postoperative priority. D: Correct - Grounding epicardial pacing wires ensures proper pacemaker function if temporary pacing is needed. E: Correct - Ensuring mediastinal chest tube patency prevents complications like tamponade or hemothorax.
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.
