Question 1 of 5
To appropriately monitor therapy and client progress, the nurse should be aware that increased myocardial work and O2 demand will occur with which of the following?
Correct Answer: A
Rationale: Inotropic therapy will increase contractility, which will increase myocardial O2 demand. Decreased heart rate to the point of bradycardia will increase coronary artery filling time. This should be used cautiously because tachycardia may be a compensatory mechanism to increase cardiac output. The goal in the care of the MI client with angina is to maintain a balance between myocardial O2 supply and demand. Decrease in systemic vascular resistance by drug therapy, such as IV nitroglycerin or nitroprusside, or intra-aortic balloon pump therapy, would decrease myocardial work and O2 demand.
Question 2 of 5
The client is prescribed warfarin (Coumadin). Which food should the nurse instruct the client to limit?
Correct Answer: A
Rationale: Spinach is high in vitamin K, which antagonizes warfarin’s anticoagulant effect, potentially reducing its efficacy. Apples, chicken, and rice have negligible vitamin K.
Question 3 of 5
A child has a nursing diagnosis of fluid volume excess related to compromised regulatory mechanisms. Which of the following nursing interventions is the most accurate measure to include in his care?
Correct Answer: A
Rationale: Although all of these interventions are important aspects of care, weight is the most sensitive indicator of fluid balance. Although monitoring intake and output is important, weight is a more accurate indicator of fluid status. Urine specific gravity does not necessarily indicate fluid volume excess. Edema may not be apparent, yet the client may have fluid volume excess.
Question 4 of 5
Following a gastric resection, a 70-year-old client is admitted to the postanesthesia care unit. He was extubated prior to leaving the suite. On arrival at the postanesthesia care unit, the nurse should:
Correct Answer: A
Rationale: Adequate air exchange and tissue oxygenation depend on competent respiratory function. Checking the airway is the nurse's priority action. Obtaining the vital signs is an important action, but it is secondary to airway management. Reorienting a client to time, place, and person after surgery is important, but it is secondary to airway and vital signs. Airway management takes precedence over physician's orders unless they specifically relate to airway management.
Question 5 of 5
The nurse is caring for a client with pneumonia who is allergic to penicillin. Which antibiotic is safest to administer to this client?
Correct Answer: C
Rationale: Erythromycin, a macrolide, is safe for penicillin-allergic patients. Cefazolin (
A), Amoxicillin (
B), and Ceftriaxone (
D) are beta-lactams with cross-reactivity risks.
