Question 1 of 5.
The surgeon orders cefazolin (Ancef) 1 g to be given I.V. at 7:30 a.m. when the client's surgery is scheduled at 8:00 a.m. What is the primary reason to start the antibiotic exactly at 7:30 a.m.?
A. Legally the medication has to be given at the ordered time.
B. The antibiotic is most effective in preventing infection if it is given 30 to 60 minutes before the operative incision is made.
C. The postoperative dose of Ancef needs to be started exactly 8 hours after the preoperative dose of Ancef.
D. The peak and titer levels are needed for antibiotic therapy.
Explanation: Administering cefazolin 30 to 60 minutes before incision ensures optimal tissue levels to prevent surgical site infections. Timing is critical for prophylactic efficacy, not legal requirements or postoperative dosing schedules.
Question 2 of 5.
The nurse is assessing a client who has had a myocardial infarction (MI). The nurse notes the cardiac rhythm shown on the electrocardiogram strip below. The nurse identifies this rhythm as which of the following?
A. Atrial fibrillation.
B. Ventricular tachycardia.
C. Premature ventricular contractions (PVCs).
D. Third-degree heart block.
Explanation: Without the ECG strip, the rhythm cannot be identified. This question is incomplete in the provided document.
Question 3 of 5.
After the administration of t-PA, the assessment priority is to:
A. Monitor the client for chest pain.
B. Monitor for fever.
C. Monitor the 12-lead electrocardiogram (ECG) every 4 hours.
D. Monitor breath sounds.
Explanation: Monitoring for chest pain post-t-PA assesses for reperfusion success or reocclusion, a priority to ensure effective thrombolysis and myocardial perfusion.
Question 4 of 5.
A client has a throbbing headache when nitroglycerin is taken for angina. The nurse should instruct the client that:
A. Acetaminophen (Tylenol) or Ibuprofen (Advil) can be taken for this common side effect.
B. Nitroglycerin should be avoided if the client is experiencing this serious side effect.
C. Taking the nitroglycerin with a few glasses of water will reduce the problem.
D. The client should lie in a supine position to alleviate the headache.
Explanation: Headache is a common side effect of nitroglycerin due to vasodilation. Acetaminophen or ibuprofen can safely relieve it without discontinuing the medication.
Question 5 of 5.
A client has returned from the cardiac catheterization laboratory after a balloon valvuloplasty for mitral stenosis. Which of the following requires immediate nursing action?
A. A low, grade 1 intensity mitral regurgitation murmur.
B. SpO2 is 94% on 2 liters of oxygen via nasal cannula.
C. The client has become more somnolent.
D. Urine output has decreased from 60 mL/hour to 40 mL over the last hour.
Explanation: Increased somnolence may indicate neurological complications (e.g., stroke) post-valvuloplasty, requiring immediate action. Other findings are less urgent.
