A nurse caring for a client who has had cardiac or vascular surgery knows to do hourly assessments on which of the following?
- A. Blood sugar level
- B. Fluid intake and urine output
- C. Mentation
- D. Arterial blood gases
Correct Answer: B
Rationale: While assessing a client undergoing cardiac or vascular surgery, the nurse assesses the client's fluid intake and urine output on an hourly basis. The nurse may assess the blood sugar level during the initial assessment process but not hourly. For a client undergoing a cardiac or vascular surgery, the nurse does not assess for mentation. Arterial blood gases would not be assessed hourly.

The nurse is caring for a client who has had cardiothoracic surgery, and the nurse is palpating the peripheral pulses. The nurse cannot palpate the left lower extremity pulse. What is the first action by the nurse?
- A. Call the physician.
- B. Call the charge nurse.
- C. Apply a vasodilator such as nitroglycerin cream on the skin surface and then palpate.
- D. Use a Doppler ultrasound device.
Correct Answer: D
Rationale: Palpate the peripheral pulses or use a Doppler ultrasound device if the pulses are not palpable. Prior to calling the physician or notifying the charge nurse, attempt to use the Doppler, and then, if no pulse is heard, the nurse may notify either. Administration of medications without a physician's prescription is contraindicated.
A client is in the intensive care unit with a diagnosis of severe uncontrolled hypertension. What method of monitoring would best meet the needs of this client?
- A. Central venous pressure monitoring
- B. Direct blood pressure monitoring
- C. Pulmonary artery pressure monitoring
- D. Manual blood pressure readings with a sphygmomanometer
Correct Answer: B
Rationale: Direct blood pressure monitoring continuously displays the waveform and indicates the client's systolic, diastolic, and mean arterial pressures. This type of equipment eliminates the need to auscultate the BP. Direct BP monitoring may be used in clients with severe and sustained hypertension or hypotension and during and after cardiac surgery. Central venous pressure monitoring would be used to detect an excess or deficit in venous blood volume and would not be indicated for this client. Pulmonary artery pressure monitoring aids in the early treatment of fluid imbalances prevents left-sided heart failure or promotes its early correction and helps monitor the client's response to treatment and would not be indicated for this client. A manual reading is dependent on who takes the BP and can vary in its readings. It is not as accurate as the direct blood pressure monitoring.

The nurse is caring for a client who is having a mitral valve replacement with a mechanical valve. What instructions should the nurse be sure the client understands prior to being discharged?
- A. The valve should last for 10 to 15 years.
- B. The client will require anticoagulation.
- C. There is a low potential for thrombi formations so anticoagulation is not necessary.
- D. The valve is prone to calcification.
Correct Answer: B
Rationale: A mechanical valve should last at least 20 years. The disadvantages are the risk for thrombi and emboli, so anticoagulation is necessary. There is a risk of bleeding, and there can be a sudden malfunction in the valve. An allograft will last 10 to 15 years. A bioprosthetic valve does not require anticoagulation but is prone to deterioration and calcification.
