EAQ test 4 in progress *
A nurse is auscultating a client's heart sounds. Which valves close when the first heart sounds are produced?
Mitral and tricuspid
The left foot of a client with a history of intermittent claudication becomes increasingly cyanotic and numb. Gangrene of the left foot is diagnosed, and because of the high level of arterial insufficiency, an above-the-knee amputation (AKA) is scheduled. The response that demonstrates emotional readiness for the surgery is when the client:
Participates in learning perioperative care
A client diagnosed with multiple myeloma has been given a poor prognosis. After discharge, the client plans to travel on an airplane and attend sporting events with friends and family. The nurse prepares a discharge teaching plan for this client and includes:
Preventing infection; the client is at risk for leukopenia -The bone marrow is impaired with multiple myeloma; the effectiveness of white blood cells and immunoglobulins is reduced, which increases susceptibility to bacterial infections.
A client is admitted to the emergency department after vomiting bright red blood. After the vomiting ceases and the vital signs are stabilized, the client is transferred to a medical-surgical unit. To assess for bleeding, the nurse on the medical-surgical unit should monitor the client for:
Tachycardia -Tachycardia is a cardiovascular compensatory mechanism as the effort to circulate the decreasing blood volume intensifies.
A client is hospitalized with a diagnosis of emphysema. The nurse provides teaching and should begin with which aspect of care?
The disease process and breathing exercises
A client is admitted with a higher than expected red blood cell (RBC) count. What physiological alteration does the nurse expect will result from this clinical finding?
Increased blood viscosity -Viscosity, a measure of a fluid's internal resistance to flow, is increased as the number of red cells suspended in plasma increases. The number of cells does not affect the blood pH. The hematocrit will be higher. RBCs do not affect immunity.
A nurse concludes that the simvastatin (Zocor) being administered to a client is effective. A decrease in what clinical finding supports this conclusion?
Triglycerides -Therapeutic effects of simvastatin include decreased levels of serum triglycerides, low-density lipoprotein (LDL), and cholesterol. INR is not related to simvastatin; it is a measure used to evaluate blood coagulation. Heart rate and blood pressure are not related to simvastatin.
A client appears anxious, with respirations that are shallow and 40 per minute. The client reports feeling dizzy and light-headed and having tingling sensations of the fingertips and around the lips. What does the nurse determine is the probable cause of these clinical manifestations?
hyperventilation
