Your patient is undergoing a temporary pacemaker insertion. Fifteen minutes after the procedure ends, the patient develops acute dyspnea, a BP of 60/40, & tachycardia of 140 BPM. Heart sounds are muffled & when you place your hand on the radial pulse, you detect a decrease in amplitude when the patient inspires. Breath sounds are clear to auscultation. The neck veins are elevated & your patient sates “I feel like I’m going to die”. What is the most appropriate action for you to take as the nurse?
a.) Obtain a stat CXR to rule out tension pneumothorax
b.) Provide emotional support for the patient in his end of life care.
c.) Stat page the cardiologist to retun to the cath lab as you suspect cardiac tamponade
d.) Administer epinephrine 1mg IV per standing protocol for hypotension
c.) Stat page the cardiologist to return to the cath lab as you suspect the cardiac tamponade
As the patient is decompensating rapidly, the physician may proceed directly with pericardiocentesis or call for an emergent EKG that will help with the definitive diagnosis.
It is essential for the nurse caring for a patient to understand the pathophysiology behidn shock. Which of the following statements best describes the pathophysiologic rationale for shock?
a.) Cells lack an adeauate blood supply & are deprived of oxygen & nutritents.
b.) Circulating blood volume is decreased.
c.) Blood is shunted from vital organs to peripheral areas of the body.
d.) Hemorrhage occurs as a result of trauma.
a.) Cells lack an adequate blood supply & are deprived of oxygen & nutrients
The nurse recognizes that antidiuretic hormone (ADH) plays a role during hypovolemic shock. WHich assessment finding will the nurse likely observe related to the role of ADH during hypovolemic shock?
a.) Increased hunger
b.) Increased thirst
c.) Increased urinary outut
d.) Increased capillary perfusion
b.) Increased thirst
The nurse has completed a set of vital signs for a patient at risk for shock. Which assessment finding is a potential sign of shock?
a.) Elevated systolic blood pressure
b.) Bradycardia
c.) Shallow, rapid respirations
d.) Elevated mean arterial pressrue
c.) Shallow, rapid respirations
The nurse is caring for a patient with a GI bleed who is in the compensatory phase of shock. What is an early sign that accompanies initial shock?
a.) Hyperactive bowel sounds
b.) Cool, clammy skin
c.) Increased heart rate
d.) Increased urine output
b.) Cool, clammy skin
A patient is receiving Dopamine, a vasoactive drug, to increase stroke volume for shock. The nurse should be aware of which of the following when monitoring a vasoactive drug?
a.) The drug should be discontinued immediately after blood pressure increases.
b.) The drug reduces the oxygen demands of the heart.
c.) The drug may cause respiratory alkalosis.
d.) The drug dose would be weaned prior to discontinuation.
d.) The drug dose would be weaned prior to discontinuation.
A nurse is assessing a patient for symptoms of neurogenic shock following a spinal cord injury. What should the nurse monitor the patient for symptoms of?
a.) Bradycardia
b.) Hypertension
c.) Cool, moist skin
d.) Cushing’s triad
a.) Bradycardia
Shock is best described as a condition in which systemic blood pressure is inadequate to deliver oxygen to tissues. The nurse knows that without prompt intervention any type of shock will eventually result in what?
a.) Decreased blood flow to the tissue & edema.
b.) A loss of sympathetic tone & hypervolemia.
c.) Anaerobic metabolism & cellular death
d.) An overwhelming inflammatory response & infection.
c.) Anaerobic metabolism & cellular death
The nurse knows that patients who are in shock have special nutritional needs. What are these special nutritional needs directly related to?
a.) Use of albumin as a food source by the body because of the need for increased caloric intake.
b.) Loss of fluid due to stress ulcers & decreased stomach acids due to increased parasympathetic activity.
c.) Release of catecholamines that create an increase in metabolic rate & caloric requirements.
d.) Increase in gastrointestinal function during shock & the resulting diarrhea.
c.) Release of catecholamines that creates an increase in metabolic rate & caloric requirements
