A. Lanoxin increases the heart rate
Lanoxin does not typically increase heart rate significantly.
B. Lanoxin increases the force of cardiac contractions
Digoxin (Lanoxin) is a positive inotropic agent, meaning it increases the force of cardiac contractions.
C. Lanoxin order should be questioned in this diagnosis.
Lanoxin is commonly used in the treatment of heart failure.
D. Lanoxin decreases the force of cardiac contractions
Lanoxin does not decrease the force of cardiac contractions.

A nurse is providing teaching to a client who has a permanent pacemaker and has just had the initial pacemaker check. Which of the following client statements indicates to the nurse that the teaching was effective?
A. "The next pacemaker check will be when the batteries need to be replaced."
Regular pacemaker checks are scheduled periodically, not only when the battery needs replacement.
B. "My pacemaker will need reprogramming if I stand too close to a microwave oven."
Modern pacemakers are well-shielded and are not affected by household microwaves.
C. "I will take my pulse weekly."
Clients should check their pulse daily to ensure proper pacemaker function, not just weekly.
D. "The pacemaker can be checked from home by using the telephone."
Many pacemakers can be checked remotely using telephone or wireless technology, allowing for convenient monitoring.

A nurse is caring for a client who has deep vein thrombosis and has been on heparin continuous infusion for 5 days. The provider prescribes warfarin PO without discontinuing the heparin. The client asks the nurse why both anticoagulants are necessary. Which of the following statements should the nurse make?
A. "I will call the provider to get a prescription for discontinuing the IV heparin today."
Discontinuing heparin abruptly without achieving therapeutic levels of warfarin increases the risk of thrombus formation.
B. "Both heparin and warfarin work together to dissolve the clots."
Heparin and warfarin have different mechanisms of action, but they both serve to prevent clot formation.
C. "The IV heparin increases the effects of the warfarin and decreases the length of your hospital stay."
Heparin and warfarin do not directly affect each other's therapeutic effects.
D. "Warfarin takes several days to work, so the IV heparin will be used until the warfarin reaches a therapeutic level."
Warfarin takes time to reach therapeutic levels and become effective, so heparin is continued until warfarin is fully active.

A nurse is caring for a client who reports shortness of breath and heart palpitations. An ECG confirms the client is experiencing ventricular tachycardia (VT). The nurse notes a carotid pulse with a BP of 70 systolic, the client reports feeling dizzy. The nurse should anticipate the need for which priority action?
A. Radiofrequency catheter ablation
Radiofrequency catheter ablation is a long-term treatment for recurrent VT, not an immediate intervention.
B. CPR
CPR is indicated for pulseless VT, but this client has a carotid pulse.
C. Defibrillation
Defibrillation is used for pulseless VT or ventricular fibrillation, but this client is still perfusing.
D. Synchronized cardioversion
Synchronized cardioversion is the appropriate treatment for unstable VT with a pulse, as it delivers a timed shock to restore normal rhythm.
