Question 1

A patient has a stroke volume of 75 mL and a heart rate of 88 beats/min. What should the nurse calculate this patient's cardiac output to be?

Accepted Answer

The answer of A patient has a stroke volume of...

Question 2

While collecting data, a patient expectorates pink, frothy sputum. Which health problem should the nurse consider is occurring in this patient?

Accepted Answer

Pink, frothy sputum is a classic sign of pulmonary edema, which is often a result of heart failure. This symptom indicates fluid accumulation in the lungs.

Question 3

The nurse is caring for a patient with peripheral vascular disease. Which signs or symptoms should the nurse expect to observe in this patient? (Select all that apply.)

Accepted Answer

The answer of The nurse is caring for a patient...

Question 4

The nurse is assessing a patient and notes a prolonged, very loud swishing sound. The nurse knows this describes which of the following?

Accepted Answer

A murmur is described as a prolonged, very loud swishing sound, which is caused by turbulent blood flow through the heart or great vessels.

Question 5

The nurse is caring for a patient with decreased arterial blood flow. Which clinical manifestations can the nurse expect to document? (Select all that apply.)

Accepted Answer

Decreased arterial blood flow can lead to decreased hair distribution, thick, brittle nails, and shiny skin due to poor circulation and nutrient delivery to the extremities. Varicose veins and moist skin are more associated with venous issues rather than arterial insufficiency.

Question 6

The nurse is caring for a patient with a potassium level of 7.6 mEq/L. For which HCP-ordered test should the nurse prepare the patient?

Accepted Answer

A potassium level of 7.6 mEq/L is significantly elevated and can lead to life-threatening cardiac dysrhythmias. An Electrocardiogram (ECG) is the appropriate test to assess for these potential changes.

Question 7

The nurse is caring for a patient who is having an exercise treadmill test. What interventions would be appropriate for the test? (Select all that apply.)

Accepted Answer

Monitoring vital signs and the electrocardiogram (ECG) before, during, and after the test are essential to assess the patient's cardiovascular response to exercise and to ensure safety.

Question 8

A patient being treated for a severe blood loss has a BP of 90/56 mm Hg and urine output of 10 mL over the last hour. Which physiological mechanism should the nurse recall is occurring in this patient?

Accepted Answer

The renin-angiotensin-aldosterone system plays a crucial role in regulating blood pressure and fluid balance, especially during conditions of low blood pressure and reduced kidney perfusion, such as severe blood loss. This system leads to the retention of sodium and water, helping to increase blood volume and blood pressure.

Question 9

The nurse notes that a patient's lower legs are brown and the feet are blue when they are in the dependent position. For which health problem should the nurse collect additional data?

Accepted Answer

The brown discoloration of the lower legs and blue discoloration of the feet when dependent are indicative of venous blood flow problems, suggesting issues with venous return or venous insufficiency.

Question 10

The nurse is reviewing the medication history for a patient about to undergo cardiac surgery. Which medication should the nurse report to the surgeon?

Accepted Answer

Warfarin (Coumadin) is an anticoagulant that increases the risk of bleeding, especially during surgery. It is crucial to report this medication to the surgeon to manage the risk of excessive bleeding during cardiac surgery.

Question 11

The nurse is reinforcing teaching for a patient who is to wear a Holter monitor. Which of the following should the nurse include? (Select all that apply.)

Accepted Answer

The nurse should instruct the patient to push the event button when symptoms occur (C), keep an accurate diary of symptoms and activities (D), and avoid showers or baths while wearing the monitor (E) to ensure accurate data collection and prevent damage to the device.
