Extract:
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
A client is admitted to the emergency room with a gunshot wound to the right arm. After dressing the wound and administering the prescribed antibiotic, the nurse should:
Correct Answer: C
Rationale: Immobilizing the arm with a splint is critical to prevent further damage to the injured area, reduce pain, and promote healing. Asking about allergies should have been done prior to administering antibiotics, checking immunization records is not a priority in this acute situation, and pain medication, while important, is secondary to stabilizing the injury.
Question 3 of 5
The nurse is caring for a client with a history of heart failure. Which discharge instruction is most important?
Correct Answer: A
Rationale: Daily weight monitoring detects fluid retention early in heart failure, allowing timely intervention. Exercise should be moderate, sodium restricted, and pain relievers used cautiously.
Question 4 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 5 of 5
An 18-month-old is admitted to the hospital with acute laryngotracheobronchitis. When assessing the respiratory status, the nurse should expect to find:
Correct Answer: A
Rationale: Acute laryngotracheobronchitis (croup) typically presents with inspiratory stridor and a harsh, barking cough due to subglottic airway inflammation.
