A pacemaker is surgically implanted before a patient is safely extubated. The patient becomes tachypneic and dyspneic three hours later. Crackles in the posterior lobes are audible to the nurse and are most likely caused by

Correct! Wrong!

These signs and symptoms are typical with pulmonary edema. Typically, crackles signify air flowing through the fluid. There is no connection between crackles in the posterior lobes and pulmonary embolus. Usually, atelectasis does not exhibit bilateral crackles. Asthma often manifests earlier in the postoperative phase and is characterized by mild to loud wheezes.

Which evaluation result should the nurse anticipate for a patient who has been admitted with arterial occlusion of the limb?

Correct! Wrong!

Acute thrombosis-related occlusion symptoms include severe pain that comes on suddenly, loss of pulse, collapse of superficial veins, pallor, and decreased motor and sensory function.

With each inspiration by the patient, the nurse observes a significant reduction in the arterial line waveform. Which complication should the nurse monitor for as it develops?

Correct! Wrong!

During inspiration, the BP decrease is exceptionally big. Pulsus paradoxus, which can occur in cardiac tamponade, is often diagnosed by an inspiratory drop of SBP greater than 10 mm HG.

A patient who has ST-segment elevation in leads II, III, and aVF with high troponin is hospitalized. Which medicine administration should the nurse initially prepare for?

Correct! Wrong!

Reteplase is used for AMI when fibrinolytic therapy is recommended. In individuals with unstable angina, NSTEMI, or deep vein thrombosis, enoxaparin is a heparin substitute. For acute thrombosis, embolism, or obstructed arteriovenous cannulas, streptokinase is prescribed. For acute ischemic stroke or acute massive pulmonary embolism, alteplase is prescribed.

The nurse is examining the treatment plan for a patient with systolic heart failure who has been prescribed carvedilol (Coreg), metoprolol (Lopressor), furosemide (Lasix), and enalapril (Vasotec). What intervention will offer the MOST ACCURATE evaluation of the regimen?

Correct! Wrong!

The efficiency of a treatment regimen and compliance with it can be easily and non-invasively evaluated in heart failure patients by measuring daily weights. The patient's ability to maintain weight demonstrates both compliance and the efficacy of the treatment plan. Strict intake and output requirements are simply one part of a care plan; they do not determine whether a patient follows the recommended medical regimen or whether the program is effective. Since the bulk of the panel's components is unaffected by the medications indicated, a daily basic metabolic panel would not be useful in evaluating the efficacy of the patient's treatment plan. Repeated chest X-rays may show deteriorating heart failure.

Which of the following describes diastolic heart failure?

Correct! Wrong!

The left ventricle is unable to relax when a patient has diastolic heart failure. Heart failure symptoms and signs result from this, although the patient's EF is intact because the muscle may still contract.

Acute thrombosis-related occlusion symptoms include severe pain that comes on suddenly, loss of pulse, collapse of superficial veins, pallor, and decreased motor and sensory function.

Correct! Wrong!

The left and right atriums are cut several times during a maze treatment, causing scar tissue to develop. The course of aberrant electrical impulses is disrupted because the scar tissue does not conduct electricity. The best way to treat persistent ventricular tachycardia that is resistant to cardioversion is to implant an automated implanted cardioverter defibrillator. Low EF cardiomyopathy would benefit most from inotropic or mechanical circulatory assistance. The most effective treatment for coronary artery restenosis after PCI is antiplatelet therapy.
