Shock NCLEX Questions

A client in shock is prescribed an inotropic drug to act on alpha and beta receptors. The nurse will most likely be administering: a.) Dopamine. b.) Dobutamine. c.) Pavulon. d.) Milrinone.

a.) Dopamine.

A patient is admitted to the emergency department after sustaining abdominal injuries and a broken femur from a motor vehicle accident. The patient is pale, diaphoretic, and is not talking coherently. Vital signs upon admission are temperature 98 F (36 C), heart rate 130 beats/minute, respiratory rate 34 breaths/minute, blood pressure 50/40 mmHg. The healthcare provider suspects which type of shock? a.) Hypovolemic b.) Cardiogenic c.) Neurogenic d.) Distributive

a.) Hypovolemic

Which type of fluid is most appropriate for volume replacement for a patient with non-hemorrhagic hypovolemic shock? a.) Lactated Ringers (LR) b.) 10% Dextrose in Water (D 10 W) c.) One-half Normal Saline (1/2% NS) d.) Packed Red Blood Cells (PRBC)

a.) Lactated Ringers (LR)

The client experiences shock following a spinal cord injury. This type of shock is classified as: a.) Hypovolemic. b.) Neurogenic. c.) Cardiogenic. d.) Anaphylactic.

a.) Neurogenic.

A client has been diagnosed with sepsis. The nurse will most likely find which of the following when assessing this client: Select all that apply: a.) Rapid shallow respirations. b.) Severe hypotension. c.) Mental status changes. d.) Elevated temperature. e.) Lactic acidosis. f.) Oliguria.

a.) Rapid shallow respirations. d.) Elevated temperature.

The client in shock is prescribed an infusion of lactated Ringer's solution. The nurse recognizes that the function of this fluid in the treatment of shock is to: a.) Replace fluid, and promote urine output. b.) Draw water into cells. c.) Draw water from cells to blood vessels. d.) Maintain vascular volume.

a.) Replace fluid, and promote urine output.

A patient in compensated septic shock has hemodynamic monitoring with a pulmonary artery catheter and an arterial catheter. Which information obtained by the nurse indicates that the patient is still in the compensatory stage of shock? a.) The cardiac output is elevated. b.) The central venous pressure (CVP) is increased. c.) The systemic vascular resistance (SVR) is high. d.) The PAWP is high.

a.) The cardiac output is elevated. Rationale: In the early stages of septic shock, the cardiac output is high. The other hemodynamic changes would indicate that the patient had developed progressive or refractory septic shock.

A patient with a myocardial infarction (MI) and cardiogenic shock has the following vital signs: BP 86/50, pulse 126, respirations 30. Hemodynamic monitoring reveals an elevated PAWP and decreased cardiac output. The nurse will anticipate: a.) administration of furosemide (Lasix) IV. b.) titration of an epinephrine (Adrenalin) drip. c.) administration of a normal saline bolus. d.) assisting with endotracheal intubation.

a.) administration of furosemide (Lasix) IV. Rationale: The PAWP indicates that the patient's preload is elevated and furosemide is indicated to reduce the preload and improve cardiac output. Epinephrine would further increase myocardial oxygen demand and might extend the MI. The PAWP is already elevated, so normal saline boluses would be contraindicated. There is no indication that the patient requires endotracheal intubation.

When assessing the hemodynamic information for a newly admitted patient in shock of unknown etiology, the nurse will anticipate administration of large volumes of crystalloids when the a.) cardiac output is increased and the central venous pressure (CVP) is low. b.) pulmonary artery wedge pressure (PAWP) is increased, and the urine output is low. c.) heart rate is decreased, and the systemic vascular resistance is low. d.) cardiac output is decreased and the PAWP is high.

a.) cardiac output is increased and the central venous pressure (CVP) is low. Rationale: A high cardiac output and low CVP suggest septic shock, and massive fluid replacement is indicated. Increased PAWP indicates that the patient has excessive fluid volume (and suggests cardiogenic shock), and diuresis is indicated. Bradycardia and a low systemic vascular resistance (SVR) suggest neurogenic shock, and fluids should be infused cautiously.

An intensive care nurse, is assessing a patient with suspected sepsis. Which predisposing factors would expect to be found in the patient with septic shock? a.) A 45 year old client with a history of renal insufficiency. b.) A client age 65, with a history of cancer who is recovering from an abdominal peritoneal resection. c.) A 27 year old with pyelonephritis responding to treatment with an antibiotic. d.) A 50 year old with community acquired tuberculosis.

b.) A client age 65, with a history of cancer who is recovering from an abdominal peritoneal resection.

Dobutamine (Dobutrex) is used to treat a client experiencing cardiogenic shock. Nursing intervention includes: a.) Monitoring for fluid overload. b.) Monitoring for cardiac dysrhythmias. c.) Monitoring respiratory status. d.) Monitoring for hypotension.

b.) Monitoring for cardiac dysrhythmias. Rationale: Dobutamine is beneficial in cases where shock is caused by heart failure. The drug increases contractility, and has the potential to cause dysrhythmias.

A patient who is receiving chemotherapy is admitted to the hospital with acute dehydration caused by nausea and vomiting. Which action will the nurse include in the plan of care to best prevent the development of shock, systemic inflammatory response syndrome (SIRS), and multiorgan dysfunction syndrome (MODS)? a.) Administer all medications through the patient's indwelling central line. b.) Place the patient in a private room. c.) Restrict the patient to foods that have been well-cooked or processed. d.) Insert a nasogastric (NG) tube for enteral feeding.

b.) Place the patient in a private room. Rationale: The patient who has received chemotherapy is immune compromised, and placing the patient in a private room will decrease the exposure to other patients and reduce infection/sepsis risk. Administration of medications through the central line increases the risk for infection and sepsis. There is no indication that the patient is neutropenic, and restricting the patient to cooked and processed foods is likely to decrease oral intake further and cause further malnutrition, a risk factor for sepsis and shock. Insertion of an NG tube is invasive and will not decrease the patient's nausea and vomiting.

To monitor a patient with severe acute pancreatitis for the early organ damage associated with MODS, the most important assessments for the nurse to make are a.) stool guaiac and bowel sounds. b.) lung sounds and oxygenation status. c.) serum creatinine and urinary output. d.) serum bilirubin levels and skin color.

b.) lung sounds and oxygenation status. Rationale: The respiratory system is usually the FIRST system to show the signs of MODS because of the direct effect of inflammatory mediators on the pulmonary system. The other assessment data are also important to collect, but they will not indicate the development of MODS as early.

A patient is treated in the emergency department (ED) for shock of unknown etiology. The first action by the nurse should be to a.) check the blood pressure. b.) obtain an oxygen saturation. c.) attach a cardiac monitor. d.) check level of consciousness.

b.) obtain an oxygen saturation. Rationale: The initial actions of the nurse are focused on the ABCs, and assessing the airway and ventilation is necessary. The other assessments should be accomplished as rapidly as possible after the oxygen saturation is determined and addressed.

While caring for a seriously ill patient, the nurse determines that the patient may be in the compensatory stage of shock on finding a.) cold, mottled extremities. b.) restlessness and apprehension. c.) a heart rate of 120 and cool, clammy skin. d.) systolic BP less than 90 mm Hg.

b.) restlessness and apprehension. Rationale: Restlessness and apprehension are typical during the compensatory stage of shock. Cold, mottled extremities, cool and clammy skin, and a systolic BP less than 90 are associated with the progressive and refractory stages.

A 4.5 kg infant is admitted to the pediatric intensive care unit after 33 days of watery diarrhea. The infant is diagnosed with severe dehydration. The infant's skin is mottled and turgor is poor. Capillary refill is delayed, and there is an absence of tears with crying. Which intervention should be the priority action by the healthcare provider? a.) Calculate the mean arterial pressure b.) Draw blood for a complete blood count c.) Establish vascular access d.) Take a complete set of vital signs

c.) Establish vascular access Rationale: Vascular access should be established quickly in order to replace lost volume before shock progresses.

The healthcare provider is caring for a patient who has septic shock. Which of these should the healthcare provider administer to the patient first? a.) Antibiotics to treat the underlying infection. b.) Corticosteroids to reduce inflammation. c.) IV fluids to increase intravascular volume. d.) Vasopressors to increase blood pressure.

c.) IV fluids to increase intravascular volume. Rationale: Circulation and perfusion are addressed first so IV fluids will be started immediately. After blood cultures are obtained, broad-spectrum antibiotics should be administered without delay. Vasopressors are administered if the patient is not responding to the fluid challenge. Corticosteroids may be considered to address the inflammatory-induced vasodilation and capillary leakage.

A patient who has pericarditis related to radiation therapy, becomes dyspneic, and has a rapid, weak pulse. Heart sounds are muffled, and a 12 mmHg drop in blood pressure is noted on inspiration. The healthcare provider's interventions are aimed at preventing which type of shock? a.) Distributive b.) Neurogenic c.) Obstructive d.) Cardiogenic

c.) Obstructive Rationale: Obstructive shock can be caused by anything that impedes the heart's ability to contract and pump blood around the body, as with cardiac tamponade.

Which of the following assessment findings is an early indication of hypovolemic shock? a.) Diminished bowel sounds b.) Increased urinary output c.) Tachycardia d.) Hypertension

c.) Tachycardia Rationale: Tachycardia is an early symptom as the body compensates for a declining blood pressure the heart rate increases to circulate the blood faster to prevent tissue hypoxia.

Multiple organ dysfunction syndrome (MODS) develops in severe sepsis as a result of systemic inflammatory response syndrome (SIRS), disseminated intravascular coagulation and damage to the endothelium. Which of the following statements best describes the management of MODS? a.) The use of proton pump inhibitors and H2 agents to increase the pH of the stomach inhibit the development of stress ulcers, an ileus and malabsorption issues. b.) Maintaining ventilator settings that ensure a tidal volume of at least 6 mL/kg of body weight will keep the lungs from being injured by endothelial damage. c.) There is no specific therapies for MODS other than supportive care and the early recognition of dysfunctional organ(s). d.) Much of the organ damage that occurs with MODS in the setting of severe sepsis is associated with pre-existing conditions.

c.) There is no specific therapies for MODS other than supportive care and the early recognition of dysfunctional organ(s).

Sepsis is the most common cause of disseminated intravascular coagulation (DIC). All of the following statements concerning this life threatening complications are true except: a.) The rapidity of onset is determined by the intensity of the trigger and is related to the condition of the patient's liver, bone marrow and endothelium. b.) In the early phase, the patient may demonstrate manifestations of thrombosis and microemboli. c.) Though a coagulopathy is present, excessive blood loss rarely results in hemorrhagic shock. d.) The most critical intervention for DIC is the early identification and treatment of the underlying disorder.

c.) Though a coagulopathy is present, excessive blood loss rarely results in hemorrhagic shock.

When caring for a patient who has just been admitted with septic shock, which of these assessment data will be of greatest concern to the nurse? a.) BP 88/56 mm Hg b.) Apical pulse 110 beats/min c.) Urine output 15 ml for 2 hours d.) Arterial oxygen saturation 90%

c.) Urine output 15 ml for 2 hours Rationale: The best data for assessing the adequacy of cardiac output are those that provide information about end-organ perfusion such as urine output by the kidneys. The low urine output is an indicator that renal tissue perfusion is inadequate and the patient is in the progressive stage of shock. The low BP, increase in pulse, and low-normal O2 saturation are more typical of compensated septic shock.

A patient with massive trauma and possible spinal cord injury is admitted to the ED. The nurse suspects that the patient may be experiencing neurogenic shock in addition to hypovolemic shock, based on the finding of a.) cool, clammy skin. b.) shortness of breath. c.) heart rate of 48 beats/min d.) BP of 82/40 mm Hg.

c.) heart rate of 48 beats/min Rationale: The normal sympathetic response to shock/hypotension is an increase in heart rate. The presence of bradycardia suggests unopposed parasympathetic function, as occurs in neurogenic shock. The other symptoms are consistent with hypovolemic shock.

A patient in septic shock has not responded to fluid resuscitation, as evidenced by a decreasing BP and cardiac output. The nurse anticipates the administration of a.) nitroglycerine (Tridil). b.) dobutamine (Dobutrex). c.) norepinephrine (Levophed). d.) sodium nitroprusside (Nipride).

c.) norepinephrine (Levophed). Rationale: When fluid resuscitation is unsuccessful, administration of vasopressor drugs is used to increase the systemic vascular resistance (SVR) and improve tissue perfusion. Nitroglycerin would decrease the preload and further drop cardiac output and BP. Dobutamine will increase stroke volume, but it would also further decrease SVR. Nitroprusside is an arterial vasodilator and would further decrease SVR.

A patient with hypovolemic shock has a urinary output of 15 ml/hr. The nurse understands that the compensatory physiologic mechanism that leads to altered urinary output is a.) activation of the sympathetic nervous system (SNS), causing vasodilation of the renal arteries. b.) stimulation of cardiac -adrenergic receptors, leading to increased cardiac output. c.) release of aldosterone and antidiuretic hormone (ADH), which cause sodium and water retention. d.) movement of interstitial fluid to the intravascular space, increasing renal blood flow.

c.) release of aldosterone and antidiuretic hormone (ADH), which cause sodium and water retention. Rationale: The release of aldosterone and ADH lead to the decrease in urine output by increasing the reabsorption of sodium and water in the renal tubules. SNS stimulation leads to renal artery vasoconstriction. -Receptor stimulation does increase cardiac output, but this would improve urine output. During shock, fluid leaks from the intravascular space into the interstitial space.

When compensatory mechanisms for hypovolemic shock are activated, the nurse would expect which two patient findings to normalize? a.) Intensity of peripheral pulses and body temperature. b.) Peripheral pulses and heart rate (HR). c.) Metabolic alkalosis and oxygen saturation. d.) Cardiac output (CO) and blood pressure (BP).

d.) Cardiac output (CO) and blood pressure (BP).
