The nurse is caring for a client with a permanent pacemaker. The client's monitor shows a pacemaker spike prior to the p wave. What would be the nurse's best action?

Increase the pacemaker sensitivity

Document that the pacemaker is regular

Set the pacemaker to the asynchronous mode

Document that the atria are being paced

Answer and Explanation

The Correct Answer is D

A. Increase the pacemaker sensitivity: Adjusting pacemaker sensitivity is a technical function typically managed by a cardiologist or device technician. There is no indication from the information provided that the pacemaker is under- or over-sensing, so no adjustment is warranted.

B. Document that the pacemaker is regular: While the pacemaker may be functioning regularly, this statement is vague and does not accurately describe the observed pacing activity. The key observation is the spike occurring before the P wave, which requires more specific documentation.

C. Set the pacemaker to the asynchronous mode: Asynchronous pacing means the pacemaker fires at a set rate regardless of the patient's intrinsic rhythm and is generally reserved for specific situations such as during surgery or when interference with sensing is suspected. There is no evidence of pacemaker malfunction or need to override sensing in this scenario.

D. Document that the atria are being paced: A pacemaker spike immediately before the P wave indicates atrial pacing. This means the pacemaker is stimulating the atria, leading to atrial depolarization. This is the appropriate interpretation and should be documented clearly.

Correct Answer is B

Explanation

A. "All patients with this disorder have a genetic defect which causes it.": Restrictive cardiomyopathy is not primarily a genetic disorder. While there may be rare familial forms, most cases are acquired, often secondary to systemic diseases, making this statement inaccurate and misleading.

B. "There are many theories about its development but amyloidosis in your history is a probable cause.": This is the most accurate response. Restrictive cardiomyopathy is commonly associated with infiltrative diseases such as amyloidosis, hemochromatosis, and sarcoidosis, which impair ventricular filling due to stiff, non-compliant myocardium.

C. "You probably had a silent heart attack which caused this disorder.": Silent myocardial infarctions can contribute to ischemic cardiomyopathy, typically leading to dilated, not restrictive, changes in the myocardium. They are not a primary cause of restrictive cardiomyopathy.

D. "Your long-standing hypertension caused this disorder.": Chronic hypertension more commonly leads to left ventricular hypertrophy and may contribute to diastolic heart failure, but it is not a typical cause of restrictive cardiomyopathy.

A. gabapentin & acetaminophen B. extended release opioids C. sitting & leaning forward D. supine with head of bed 15 degrees

Correct Answer is C

Explanation

A. gabapentin & acetaminophen: While acetaminophen may help with pain relief, gabapentin is primarily used for neuropathic pain and not effective for the inflammatory chest pain associated with pericarditis. These medications do not address the positional nature of pericardial pain.

B. extended release opioids: Opioids may provide general pain relief but are not the standard treatment for pericarditis-related pain. They do not address the inflammatory cause and carry risks of sedation and respiratory depression without improving cardiac inflammation.

C. sitting & leaning forward: Pericarditis pain is classically relieved by having the patient sit up and lean forward. This position reduces pressure on the pericardium and decreases pain by allowing the inflamed pericardial layers to separate slightly, reducing friction.

D. supine with head of bed 15 degrees: Lying flat or even slightly elevated can worsen pericarditis pain because it increases pressure on the inflamed pericardium. Patients often report increased discomfort in the supine position, making it less favorable for symptom relief.

The patient with restrictive cardiomyopathy asks the nurse what could have caused this disorder. Which response by the nurse is most accurate?

Correct Answer is B

Explanation

The nurse understands that chest pain related to pericarditis is classically relieved by

Correct Answer is C

Explanation

To properly identify a cardiac rhythm, the nurse will determine if the client's rhythm contains the following factors: (Select All that Apply.)

A client is admitted with uncontrolled atrial fibrillation with a rate between 120's-130's. IV heparin therapy is prescribed. In addition, the nurse prepares the client for a transesophageal echocardiogram (TEE). What does the nurse understand about this diagnostic study?

Rhythm Strip The nurse is evaluating the following rhythm strip on a client in the telemetry unit. The client is alert and oriented but is complaining of slight nausea after eating breakfast. What is the nurse's best action?

A client has a triple lumen subclavian central venous catheter (CVC) with D51/2NS infusing through one lumen (port) at 75 mL per hour. The nurse has an order to transfuse one unit of packed red blood cells (PRBCs). The nurse's safest action is to:

A client with paroxysmal supraventricular tachycardia asks the nurse why the health care provider (HCP) is going to perform carotid sinus massage. The nurse educates the client about the treatment. Which statement by the client indicates that the teaching has been effective?

A client has been admitted to the Post Anesthesia Care Unit (PACU) after a completing electroconvulsant therapy (ECT) treatment. Which action will the nurse perform first?
