Question 1 of 5
The nurse provides care for a post-cardiac catheterization male client in the postprocedure room. Which is a priority nursing action for this client?
Correct Answer: D
Rationale: Following cardiac catheterization, the client has a pressure dressing placed over the catheter site to control bleeding. After the procedure, the nurse checks the dressing over the insertion site frequently for signs of bleeding. Additionally, the nurse monitors the client's blood pressure (BP) and pulse frequently to detect complications; however, it is not a priority for the nurse to monitor the client's temperature after this procedure. Although the client is encouraged to drink fluids as part of the discharge instructions to assist with flushing the dye used during the procedure, this is not a priority nursing action for this client in the postprocedure period of care. The client is taught to void while lying flat using a urinal; however, this is not the priority action based on the current data.
Question 2 of 5
The nurse is caring for an elderly client with left-sided heart failure. When auscultating lung sounds, which adventitious sound is expected?
Correct Answer: C
Rationale: When the left side of the heart is pumping inefficiently, blood backs up into the pulmonary veins and lung tissue. Auscultation reveals a crackling sound. Wheezes and gurgles may also be heard.
Question 3 of 5
The nurse instructor is teaching a group of nursing students about adventitious heart sounds. The instructor explains that auscultation of the heart requires familiarization with normal and abnormal heart sounds. What would the instructor tell these students a ventricular gallop indicates in an adult?
Correct Answer: A
Rationale: A sound that follows S1 and S2 is called an S3 heart sound or a ventricular gallop. An S3, normal in children, often is an indication of heart failure in an adult. An extra sound before S1 is an S4 heart sound, or atrial gallop. An S4 sound often is associated with hypertensive heart disease. A friction rub may cause a rough, grating, or scratchy sound that is an indication of pericarditis or inflammation of the pericardium.
Question 4 of 5
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?
Correct Answer: A
Rationale: Attached to the mitral and tricuspid valves are cordlike structures known as chordae tendineae, which in turn attach to papillary muscles, two major muscular projections from the ventricles. Neither atrioventricular tendons, semilunar tendineae, nor papillary tendons hold the tricuspid valve in place.
Question 5 of 5
The nurse is discharging a client after a cardiac catheterization. What would the nurse include in the discharge teaching?
Correct Answer: B
Rationale: Instructions for the client and family include: Keep the extremity straight for several hours and avoid movement; Report any warm, wet feeling that may indicate oozing blood, numbness, tingling, or sharp pain in the extremity; Drink a large volume of fluid to relieve thirst and promote the excretion of the dye. There is no need to eat only soft foods after a cardiac catheterization.
