contact the health care provider and report the findings

A nurse assessing a client who underwent cardiac catheterization finds the client lying flat on the bed. The client's temperature is 99.8° F (37.7° C). The client's blood pressure is 104/68 mm Hg. The client's pulse rate is 76 beats/minute. The nurse detects weak pulses in the leg distal to the puncture site. Skin on the leg is cool to the touch. The puncture site is dry, but swollen. What is the most appropriate action for the nurse to take?

B-type natriuretic peptide (BNP)

A nurse is checking laboratory values on a client who has crackles in the lower lobes, 2+ pitting edema, and dyspnea with minimal exertion. Which laboratory value does the nurse expect to be abnormal?

Before a transesophageal echocardiogram, a nurse gives a client an oral topical anesthetic spray. When the client returns from the procedure, the nurse observes no active gag reflex. What nursing action is a priority?

hypertensive heart disease

During the auscultation of heart, what is revealed by an atrial gallop?

left atrium

Each chamber of the heart has a particular role in maintaining cellular oxygenation. Which chamber is responsible for receiving oxygenated blood from the lungs?

the client is at risk for renal failure due to the contrast agent that will be given during the procedure

The client is admitted for a scheduled cardiac catheterization. On the morning of the procedure, while assessing the client's morning laboratory values, the nurse notes a blood urea nitrogen (BUN) of 34 mg/dL and a creatinine of 4.2 mg/dL. What priority reason will the nurse notify the healthcare provider?

apricots, dried peas and beans, dates

The client states, "My doctor says that because I am now taking this water pill, I need to eat more foods that contain potassium. Can you give me some ideas about what foods would be good for this?" What is the appropriate response by the nurse?

edema is collected in dependent extremities during the day; at night when the client lays down, it is reabsorbed into the circulation and excreted by the kidneys

The client with a diagnosis of heart failure reports frequently awakening during the night with the need to urinate. What explanation will the nurse offer to explain the urination?

count the heart rate at the apex

The clinic nurse caring for a client with a cardiovascular disorder is performing an assessment of the client's pulse. Which of the following steps is involved in determining the pulse deficit?

rate, quality, rhythm

The clinic nurse is assessing a client's pulse before outpatient diagnostic testing. What should the nurse document when assessing the client's pulse?

"A woman's heart is smaller and has smaller arteries that become occluded more easily."

The nurse admits an adult female client with a medical diagnosis of "rule out MI." The client is very frightened and expresses surprise that a woman would have heart problems. What response by the nurse will be most appropriate?

heart failure

The nurse cares for a client in the emergency department who has a B-type natriuretic peptide (BNP) level of 115 pg/mL (high). The nurse recognizes that this finding is most indicative of which condition?

international normalized ratio (INR)

The nurse cares for a client prescribed warfarin orally. The nurse reviews the client's prothrombin time (PT) level to evaluate the effectiveness of the medication. Which laboratory values should the nurse also evaluate?

catheter-related bloodstream infections

The nurse cares for a client with an intra-arterial blood pressure monitoring device. The nurse recognizes the most preventable complication associated with hemodynamic monitoring includes which condition?

Metoprolol

The nurse is administering a beta blocker to a patient in order to decrease automaticity. Which medication will the nurse administer?

Phase 4

The nurse is assessing a patient's electrocardiogram (ECG). What phase does the nurse determine is the resting phase before the next depolarization?

"The physiologic demands are greatest during orgasm and are equivalent to walking 3 to 4 miles per hour on a treadmill."

The nurse is assessing vital signs on a client who is 3 months status post myocardial infarction (MI). While the healthcare provider is examining the client, the client's spouse approaches the nurse and states "We are too afraid he will have another heart attack, so we just don't have sex anymore." What is the nurse's best response?

Metoprolol

The nurse is caring for a client in the cardiac intensive care unit (CICU) after a myocardial infarction (MI). Which drug will the nurse administer that will decrease contractility?

assess the client

The nurse is caring for a client on a monitored telemetry unit. During morning assessment, the nurse notes abnormal ECG waves on the telemetry monitor. Which action would the nurse do first?

chordae tendineae

The nurse is caring for a client with a damaged tricuspid valve. The nurse knows that the tricuspid valve is held in place by which of the following?

digoxin level

The nurse is caring for a geriatric client. The client is ordered Lanoxin (digoxin) tablets 0.125mg daily for a cardiac dysrhythmia. Which of the following assessment considerations is essential when caring for this client?

the thin fibrous sac encasing the heart

The nurse is caring for a patient with a diagnosis of pericarditis. Where does the nurse understand the inflammation is located?

crackles

The nurse is caring for an elderly client with left-sided heart failure. When auscultating lung sounds, which adventitious sound is expected?

K+ 3.1 mEq/L

The nurse is reviewing the morning laboratory test results for a client with cardiac problems. Which finding is a priority to report to the healthcare provider?

heart failure

The nurse is reviewing the results of the patient's echocardiogram and observes that the ejection fraction is 35%. The nurse anticipates that the patient will receive treatment for what condition?

ST-segment changes on the EKG

The nurse observes a client during an exercise stress test (bicycle). Which finding indicates a positive test and the need for further diagnostic testing?

"Do not bend at the waist, strain, or lift heavy objects for the next 24 hours."

The nurse reviews discharge instructions with a client who underwent a left groin cardiac catheterization 8 hours ago. Which instructions should the nurse include?

- remove the clients transform nitro patch - remove the client's jewelry - offer the client a headset to listen to music during the procedure

The nurse screens a client prior to a magnetic resonance angiogram (MRA) of the heart. Which action should the nurse complete prior to the client undergoing the procedure?

sinoatrial (SA) node

The nurse uses which term for the normal pacemaker of the heart?

contractility

What is the term for the ability of the cardiac muscle to shorten in response to an electrical impulse?

erb point

Which area of the heart is located at the third intercostal (IC) space to the left of the sternum?

While the nurse is preparing a client for a cardiac catheterization, the client states that they have allergies to seafood. Which of the following medications may the nurse give prior to the procedure?

endocardium

Within the heart, several structures and several layers all play a part in protecting the heart muscle and maintaining cardiac function. The inner layer of the heart is composed of a thin, smooth layer of cells, the folds of which form heart valves. What is the name of this layer of cardiac tissue?
