The nurse is watching the cardiac monitor, and a client's rhythm suddenly changes. There are no P waves; instead, there are fibrillatory waves before each QRS complex. How should the nurse interpret the client's heart rhythm? 1. Atrial fibrillation 2. Sinus tachycardia 3. Ventricular fibrillation 4. Ventricular tachycardia

Answer: 1 Rationale: Atrial fibrillation is characterized by a loss of P waves and fibrillatory waves before each QRS complex. The atria quiver, which can lead to thrombus formation.

A client's electrocardiogram strip shows atrial and ventricular rates of 110 beats per minute. The PR interval is 0.14 seconds, the QRS complex measures 0.08 seconds, and the PP and RR intervals are regular. How should the nurse interpret this rhythm? 1. Sinus tachycardia 2. Sinus bradycardia 3. Sinus dysrhythmia 4. Normal sinus rhythm

Answer: 1 Rationale: Sinus tachycardia has the characteristics of normal sinus rhythm, including a regular PP interval and normal-width PR and QRS intervals; however, the rate is the differentiating factor. In sinus tachycardia, the atrial and ventricular rates are greater than 100 beats per minute

The nurse in a medical unit is caring for a client with heart failure. The client suddenly develops extreme dyspnea, tachycardia, and lung crackles. The nurse immediately asks another nurse to contact the primary health care provider and prepares to implement which priority interventions? Select all that apply. 1. Administering oxygen 2. Inserting a Foley catheter 3. Administering furosemide 4. Administering morphine sulfate intravenously 5. Transporting the client to the coronary care unit 6. Placing the client in a low-Fowler's side-lying position

Answer: 1, 2, 3, 4 Rationale: Extreme dyspnea, tachycardia, and lung crackles in a client with heart failure indicate pulmonary edema, a life-threatening event. In pulmonary edema, the left ventricle fails to eject sufficient blood, and pressure increases in the lungs because of the accumulated blood. Oxygen is always prescribed, and the client is placed in a high-Fowler's position to ease the work of breathing. Furosemide, a rapid-acting diuretic, will eliminate accumulated fluid. A Foley catheter is inserted to measure output accurately. Intravenously administered morphine sulfate reduces venous return (preload), decreases anxiety, and also reduces the work of breathing. Transporting the client to the coronary care unit is not a priority intervention. In fact, this may not be necessary at all if the client's response to treatment is successful.

The nurse is monitoring a client who was diagnosed with type 1 diabetes mellitus and is being treated with NPH and regular insulin. Which manifestations would alert the nurse to the presence of a possible hypoglycemic reaction? Select all that apply. 1. Tremors 2. Anorexia 3. Irritability 4. Nervousness 5. Hot, dry skin 6. Muscle cramps

Answer: 1, 3, 4 Rationale: Decreased blood glucose levels produce autonomic nervous system symptoms, which are manifested classically as nervousness, irritability, and tremors. Option 5 is more likely to occur with hyperglycemia. Options 2 and 6 are unrelated to the manifestations of hypoglycemia. In hypoglycemia, usually the client feels hunger

The nurse is monitoring a client for adverse effects of medications. Which findings are characteristic of adverse effects of hydrochlorothiazide? Select all that apply. 1. Sulfa allergy 2. Osteoporosis 3. Hypokalemia 4. Hypouricemia 5. Hyperglycemia 6. Hypercalcemia

Answer: 1, 3, 5, 6 Rationale: Thiazide diuretics such as hydrochlorothiazide are sulfa-based medications, and a client with a sulfa allergy is at risk for an allergic reaction. Also, clients are at risk for hypokalemia, hyperglycemia, hypercalcemia, hyperlipidemia, and hyperuricemia.

The nurse is preparing a plan of care for a client with diabetes mellitus who has hyperglycemia. The nurse places priority on which client problem? 1. Lack of knowledge 2. Inadequate fluid volume 3. Compromised family coping 4. Inadequate consumption of nutrients

Answer: 2 Rationale: An increased blood glucose level will cause the kidneys to excrete the glucose in the urine. This glucose is accompanied by fluids and electrolytes, causing an osmotic diuresis leading to dehydration. This fluid loss must be replaced when it becomes severe. Options 1, 3, and 4 are not related specifically to the information in the question.

A client with a history of type 2 diabetes is admitted to the hospital with chest pain. The client is scheduled for a cardiac catheterization. Which medication would need to be withheld for 24 hours before the procedure and for 48 hours after the procedure? 1. Glipizide 2. Metformin 3. Repaglinide 4. Regular insulin

Answer: 2 Rationale: Metformin needs to be withheld 24 hours before and for 48 hours after cardiac catheterization because of the injection of contrast medium during the procedure. If the contrast medium affects kidney function, with metformin in the system the client would be at increased risk for lactic acidosis. The medications in the remaining options do not need to be withheld before and after cardiac catheterization.

A client is admitted to an emergency department, and a diagnosis of myxedema coma is made. Which action should the nurse prepare to carry out initially? 1. Warm the client. 2. Maintain a patent airway. 3. Administer thyroid hormone. 4. Administer fluid replacement.

Answer: 2 Rationale: Myxedema coma is a rare but serious disorder that results from persistently low thyroid production. Coma can be precipitated by acute illness, rapid withdrawal of thyroid medication, anesthesia and surgery, hypothermia, and the use of sedatives and opioid analgesics. In myxedema coma, the initial nursing action is to maintain a patent airway. Oxygen should be administered, followed by fluid replacement, keeping the client warm, monitoring vital signs, and administering thyroid hormones by the intravenous route.

The nurse is caring for a client who is on strict bed rest and creates a plan of care with goals related to the prevention of deep vein thrombosis and pulmonary emboli. Which nursing action is most helpful in preventing these disorders from developing? 1. Restricting fluids 2. Placing a pillow under the knees 3. Encouraging active range-of-motion exercises 4. Applying a heating pad to the lower extremities

Answer: 3 Rationale: Clients at greatest risk for deep vein thrombosis and pulmonary emboli are immobilized clients. Basic preventive measures include early ambulation, leg elevation, active leg exercises, elastic stockings, and intermittent pneumatic calf compression. Keeping the client well hydrated is essential because dehydration predisposes to clotting. A pillow under the knees may cause venous stasis. Heat should not be applied without a primary health care provider's prescription.

A client in sinus bradycardia, with a heart rate of 45 beats per minute and blood pressure of 82/60 mm Hg, reports dizziness. Which intervention should the nurse anticipate will be prescribed? 1. Administer digoxin. 2. Defibrillate the client. 3. Continue to monitor the client. 4. Prepare for transcutaneous pacing.

Answer: 4 Rationale: Sinus bradycardia is noted with a heart rate less than 60 beats per minute. This rhythm becomes a concern when the client becomes symptomatic. Hypotension and dizziness are signs of decreased cardiac output. Transcutaneous pacing provides a temporary measure to increase the heart rate and thus perfusion in the symptomatic client. Defibrillation is used for treatment of pulseless ventricular tachycardia and ventricular fibrillation. Digoxin will further decrease the client's heart rate. Continuing to monitor the client delays necessary intervention.

The home health nurse visits a client with a diagnosis of type 1 diabetes mellitus. The client reports a history of vomiting and diarrhea and tells the nurse that no food has been consumed for the last 24 hours. Which additional statement by the client indicates a need for further teaching? 1. "I need to stop my insulin." 2. "I need to increase my fluid intake." 3. "I need to monitor my blood glucose every 3 to 4 hours." 4. "I need to call my primary health care provider (PHCP) because of these symptoms."

Answer: 1 Rationale: When a client with diabetes mellitus is unable to eat normally because of illness, the client still should take the prescribed insulin or oral medication. The client should consume additional fluids and should notify the PHCP. The client should monitor the blood glucose level every 3 to 4 hours. The client should also monitor the urine for ketones during illness.

The nurse is monitoring a client newly diagnosed with diabetes mellitus for signs of complications. Which sign or symptom, if frequently exhibited in the client, indicates that the client is at risk for chronic complications of diabetes if the blood glucose is not adequately managed? 1. Polyuria 2. Diaphoresis 3. Pedal edema 4. Decreased respiratory rate

Answer: 1 Rationale: Chronic hyperglycemia, resulting from poor glycemic control, contributes to the microvascular and macrovascular complications of diabetes mellitus. Classic symptoms of hyperglycemia include polydipsia, polyuria, and polyphagia. Diaphoresis may occur in hypoglycemia. Hypoglycemia is an acute complication of diabetes mellitus; however, it does not predispose a client to the chronic complications of diabetes mellitus. Therefore, option 2 can be eliminated because this finding is characteristic of hypoglycemia. Options 3 and 4 are not associated with diabetes mellitus.

The client has developed atrial fibrillation, with a ventricular rate of 150 beats per minute. The nurse should assess the client for which associated signs and/or symptoms? Select all that apply. 1. Syncope 2. Dizziness 3. Palpitations 4. Hypertension 5. Flat neck veins

Answer: 1, 2, 3 Rationale: The client with uncontrolled atrial fibrillation with a ventricular rate more than 100 beats per minute is at risk for low cardiac output because of loss of atrial kick. The nurse assesses the client for palpitations, chest pain or discomfort, hypotension, pulse deficit, fatigue, weakness, dizziness, syncope, shortness of breath, and distended neck veins. Hypertension and flat neck veins are not associated with the loss of cardiac output.

A client has been diagnosed with hyperthyroidism. The nurse monitors for which signs and symptoms indicating a complication of this disorder? Select all that apply. 1. Fever 2. Nausea 3. Lethargy 4. Tremors 5. Confusion 6. Bradycardia

Answer: 1, 2, 4, 5 Rationale: Thyroid storm is an acute and life-threatening complication that occurs in a client with uncontrollable hyperthyroidism. Signs and symptoms of thyroid storm include elevated temperature (fever), nausea, and tremors. In addition, as the condition progresses, the client becomes confused. The client is restless and anxious and experiences tachycardia.

A client with a diagnosis of addisonian crisis is being admitted to the intensive care unit. Which findings will the interprofessional health care team focus on? Select all that apply. 1. Hypotension 2. Leukocytosis 3. Hyperkalemia 4. Hypercalcemia 5. Hypernatremia

Answer: 1, 3 Rationale: In Addison's disease, also known as adrenal insufficiency, destruction of the adrenal gland leads to decreased production of adrenocortical hormones, including the glucocorticoid cortisol and the mineralocorticoid aldosterone. Addisonian crisis, also known as acute adrenal insufficiency, occurs when there is extreme physical or emotional stress and lack of sufficient adrenocortical hormones to manage the stressor. Addisonian crisis is a life-threatening emergency. One of the roles of endogenous cortisol is to enhance vascular tone and vascular response to the catecholamines epinephrine and norepinephrine. Hypotension occurs when vascular tone is decreased and blood vessels cannot respond to epinephrine and norepinephrine. The role of aldosterone in the body is to support the blood pressure 1436by holding salt and water and excreting potassium. When there is insufficient aldosterone, salt and water are lost and potassium builds up; this leads to hypotension from decreased vascular volume, hyponatremia, and hyperkalemia. The remaining options are not associated with addisonian crisis.

A client receiving thrombolytic therapy with a continuous infusion of alteplase suddenly becomes extremely anxious and reports itching. The nurse hears stridor and notes generalized urticaria and hypotension. Which interventions should the nurse anticipate? Select all that apply. 1. Stop the infusion. 2. Raise the head of the bed. 3. Administer protamine sulfate. 4. Administer diphenhydramine. 5. Call for the Rapid Response Team (RRT).

Answer: 1, 4, 5 Rationale: The client is experiencing an anaphylactic reaction. Therefore, the priority action is to stop the infusion and notify the RRT. The client may be treated with antihistamines. Raising the head of the bed would not be helpful, as that may exacerbate the hypotension. Protamine sulfate is the antidote for heparin, so it is not useful for a client receiving alteplase

A client with diabetes mellitus demonstrates acute anxiety when admitted to the hospital for the treatment of hyperglycemia. What is the appropriate intervention to decrease the client's anxiety? 1. Administer a sedative. 2. Convey empathy, trust, and respect toward the client. 3. Ignore the signs and symptoms of anxiety, anticipating that they will soon disappear. 4. Make sure that the client is familiar with the correct medical terms to promote understanding of what is happening

Answer: 2 Rationale: Anxiety is a subjective feeling of apprehension, uneasiness, or dread. The appropriate intervention is to address the client's feelings related to the anxiety. Administering a sedative is not the most appropriate intervention and does not address the source of the client's anxiety. The nurse should not ignore the client's anxious feelings. Anxiety needs to be managed before meaningful client education can occur.

The nurse is monitoring a client with hypertension who is taking propranolol. Which assessment finding indicates a potential adverse complication associated with this medication? 1. Report of infrequent insomnia 2. Development of expiratory wheezes 3. A baseline blood pressure of 150/80 mm Hg followed by a blood pressure of 138/72 mm Hg after 2 doses of the medication 4. A baseline resting heart rate of 88 beats per minute followed by a resting heart rate of 72 beats per minute after 2 doses of the medication

Answer: 2 Rationale: Audible expiratory wheezes may indicate a serious adverse reaction, bronchospasm. Beta blockers may induce this reaction, particularly in clients with chronic obstructive pulmonary disease or asthma. Normal decreases in blood pressure and heart rate are expected. Insomnia is a frequent mild side effect and should be monitored.

636. The nurse administered intravenous bumetanide to a client being treated for heart failure. Which outcome indicates that the medication has achieved the expected effect? 1. Cough becomes productive of frothy pink sputum. 2. Urine output increases from 10 mL/hr to greater than 50 mL hourly. 3. The serum potassium level changes from 3.8 to 3.1 mEq/L (3.8 to 3.1 mmol/L). 4. B-type natriuretic peptide (BNP) factor increases from 200 to 262 ng/mL (200 to 262 mcg/L).

Answer: 2 Rationale: Bumetanide is a diuretic and expected outcomes include increased urine output, decreased crackles, and decreased weight. Potassium loss is a side effect rather than an expected effect of the diuretic. Frothy pink sputum indicates progression to pulmonary edema. A BNP greater than 100 pg/mL (100 ng/L) is indicative of heart failure; thus, a rise from a previous level indicates worsening of the condition.

A client with type 1 diabetes mellitus who takes NPH daily in the morning calls the nurse to report recurrent episodes of hypoglycemia with exercising. Which statement by the client indicates an adequate understanding of the peak action of NPH insulin and exercise? 1. "I should not exercise since I am taking insulin." 2. "The best time for me to exercise is after breakfast." 3. "The best time for me to exercise is mid- to late afternoon." 4. "NPH is a basal insulin, so I should exercise in the evening."

Answer: 2 Rationale: Exercise is an important part of diabetes management. It promotes weight loss, decreases insulin resistance, and helps control blood glucose levels. A hypoglycemic reaction may occur in response to increased exercise, so clients should exercise either an hour after mealtime or after consuming a 10- to 15-g carbohydrate snack, and they should check their blood glucose level before exercising. Option 1 is incorrect because clients with diabetes should exercise, though they should check with their primary health care provider before starting a new exercise program. Option 3 in incorrect; clients should avoid exercise during the peak time of insulin. NPH insulin peaks at 4 to 12 hours; therefore, afternoon exercise takes place during the peak of the medication. Option 4 is incorrect; NPH insulin is an intermediate acting insulin, not a basal insulin.

A client is wearing a continuous cardiac monitor, which begins to sound its alarm. The nurse sees no electrocardiographic complexes on the screen. Which is the priority nursing action? 1. Call a code. 2. Check the client's status. 3. Call the health care provider. 4. Document the lack of complexes.

Answer: 2 Rationale: Sudden loss of electrocardiographic complexes indicates ventricular asystole or possibly electrode displacement. Accurate assessment of the client is necessary to determine the cause and identify the appropriate intervention. The remaining options are secondary to client assessment.

A client with valvular heart disease who has a clot in the right atrium is receiving a heparin sodium infusion at 1000 units/hr and warfarin sodium 7.5 mg at 5:00 p.m. daily. The morning laboratory results are as follows: activated partial thromboplastin time (aPTT), 32 seconds; international normalized ratio (INR), 1.3. The nurse should take which action based on the client's laboratory results? 1. Collaborate with the primary health care provider (PHCP) to discontinue the heparin infusion and administer the warfarin sodium as prescribed. 2. Collaborate with the PHCP to obtain a prescription to increase the heparin infusion and continue the warfarin sodium as prescribed. 3. Collaborate with the PHCP to withhold the warfarin sodium since the client is receiving a heparin infusion and the aPTT is within the therapeutic range. 4. Collaborate with the PHCP to continue the heparin infusion at the same rate and to discuss use of dabigatran etexilate in place of warfarin sodium.

Answer: 2 Rationale: When a client is receiving warfarin for clot prevention due to atrial fibrillation, an INR of 2 to 3 is appropriate for most clients. Until the INR has achieved a therapeutic range, the client should be maintained on a continuous heparin infusion with the aPTT ranging between 60 and 80 seconds. Therefore, the nurse should collaborate with the HCP to obtain a prescription to increase the heparin infusion and to administer the warfarin as prescribed.

The nurse is monitoring a client with heart failure who is taking digoxin. Which findings are characteristic of digoxin toxicity? Select all that apply. 1. Tremors 2. Diarrhea 3. Irritability 4. Blurred vision 5. Nausea and vomiting

Answer: 2, 4, 5 Rationale: Digoxin is a cardiac glycoside. The risk of toxicity can occur with the use of this medication. Toxicity can lead to life-threatening events and the nurse needs to monitor the client closely for signs of toxicity. Early signs of toxicity include gastrointestinal manifestations such as anorexia, nausea, vomiting, and diarrhea. Subsequent manifestations include headache; visual disturbances such as diplopia, blurred vision, yellow-green halos, and photophobia; drowsiness; fatigue; and weakness. Cardiac rhythm abnormalities can also occur. The nurse also monitors the digoxin level. The optimal therapeutic range for digoxin is 0.5 to 2.0 ng/mL (0.63 to 2.56 nmol/L).

The nurse performs a physical assessment on a client with type 2 diabetes mellitus. Findings include a fasting blood glucose level of 70 mg/dL (3.9 mmol/L), temperature of 101° F (38.3° C), pulse of 82 beats per minute, respirations of 20 breaths per minute, and blood pressure of 118/68 mm Hg. Which finding would be the priority concern to the nurse? 1. Pulse 2. Respiration 3. Temperature 4. Blood pressure

Answer: 3 Rationale: In the client with type 2 diabetes mellitus, an elevated temperature may indicate infection. Infection is a leading cause of hyperosmolar hyperglycemic syndrome in the client with type 2 diabetes mellitus. The other findings are within normal limits.

A client with atrial fibrillation is receiving a continuous heparin infusion at 1000 units/hr. The nurse determines that the client is receiving the therapeutic effect based on which results? 1. Prothrombin time of 12.5 seconds 2. Activated partial thromboplastin time of 28 seconds 3. Activated partial thromboplastin time of 60 seconds 4. Activated partial thromboplastin time longer than 120 seconds

Answer: 3 Rationale: Common laboratory ranges for activated partial thromboplastin time (aPTT) are 30 to 40 seconds. Because the aPTT should be 1.5 to 2.5 times the normal value, the client's aPTT would be considered therapeutic if it was 60 seconds. Prothrombin time assesses response to warfarin therapy

The nurse is reviewing an electrocardiogram rhythm strip. The P waves and QRS complexes are regular. The PR interval is 0.16 seconds, and QRS complexes measure 0.06 seconds. The overall heart rate is 64 beats per minute. Which action should the nurse take? 1. Check vital signs. 2. Check laboratory test results. 3. Monitor for any rhythm change. 4. Notify the primary health care provider.

Answer: 3 Rationale: Normal sinus rhythm is defined as a regular rhythm, with an overall rate of 60 to 100 beats per minute. The PR and QRS measurements are normal, measuring between 0.12 and 0.20 seconds and 0.04 and 0.10 seconds, respectively. There are no irregularities in this rhythm currently, so there is no immediate need to check vital signs or laboratory results, or to notify the primary health care provider. Therefore, the nurse would continue to monitor the client for any rhythm change

The nurse should report which assessment finding to the primary health care provider (PHCP) before initiating thrombolytic therapy in a client with pulmonary embolism? 1. Adventitious breath sounds 2. Temperature of 99.4° F (37.4° C) orally 3. Blood pressure of 198/110 mm Hg 4. Respiratory rate of 28 breaths per minute

Answer: 3 Rationale: Thrombolytic therapy is contraindicated in severe uncontrolled hypertension because of the risk of cerebral hemorrhage. Therefore, the nurse would report the results of the blood pressure to the PHCP before initiating therapy.

The nurse is preparing a client with a new diagnosis of hypothyroidism for discharge. The nurse determines that the client understands discharge instructions if the client states that which signs and symptoms are associated with this diagnosis? Select all that apply. 1. Tremors 2. Weight loss 3. Feeling cold 4. Loss of body hair 5. Persistent lethargy 6. Puffiness of the face

Answer: 3, 4, 5, 6 Rationale: Feeling cold, hair loss, lethargy, and facial puffiness are signs of hypothyroidism. Tremors and weight loss are signs of hyperthyroidism. Test-Taking Strategy: Focus on the subject, signs and symptoms associated with hypothyroidism. Options 1 and 2 can be eliminated if you remember that in hypothyroidism there is an under secretion of thyroid hormone that causes the metabolism to slow down

A client is receiving a continuous intravenous infusion of heparin sodium to treat deep vein thrombosis. The client's activated partial thromboplastin time (aPTT) is 65 seconds. The nurse anticipates that which action is needed? 1. Discontinuing the heparin infusion 2. Increasing the rate of the heparin infusion 3. Decreasing the rate of the heparin infusion 4. Leaving the rate of the heparin infusion as is

Answer: 4 Rationale: The normal aPTT varies between 30 and 40 seconds (30 and 40 seconds), depending on the type of activator used in testing. The therapeutic dose of heparin for treatment of deep vein thrombosis is to keep the aPTT between 1.5 (45 to 60) and 2.5 (75 to 100) times normal. This means that the client's value should not be less than 45 seconds or greater than 100 seconds. Thus, the client's aPTT is within the therapeutic range and the dose should remain unchanged.

Prior to administering a client's daily dose of digoxin to treat heart failure, the nurse reviews the client's laboratory data and notes the following results: serum calcium, 9.8 mg/dL (2.45 mmol/L); serum magnesium, 1.0 mEq/L (0.4 mmol/L); serum potassium, 4.1 mEq/L (4.1 mmol/L); serum creatinine, 0.9 mg/dL (79.5 mcmol/L). Which result should alert the nurse that the client is at risk for digoxin toxicity? 1. Serum calcium level 2. Serum potassium level 3. Serum creatinine level 4. Serum magnesium level

Answer: 4 Rationale: An increased risk of toxicity exists in clients with hypercalcemia, hypokalemia, hypomagnesemia, hypothyroidism, and impaired renal function. The calcium, creatinine, and potassium levels are all within normal limits. The normal range for magnesium is 1.8-2.6 mEq/L (0.74-1.07 mmol/L), and the results in the correct option are reflective of hypomagnesemia

A client with diabetes mellitus has had a right below-knee amputation. Given the client's history of diabetes mellitus, which complication is the client at most risk for after surgery? 1. Hemorrhage 2. Edema of the residual limb 3. Slight redness of the incision 4. Separation of the wound edges

Answer: 4 Rationale: Clients with diabetes mellitus are more prone to wound infection, wound separation, and delayed wound healing because of the disease. Postoperative hemorrhage and edema of the residual limb are complications in the immediate postoperative period that apply to any client with an amputation. Slight redness of the incision is considered normal, as long as the incision is dry and intact.

The home health care nurse is visiting a client with coronary artery disease with elevated triglyceride levels and a serum cholesterol level of 398 mg/dL (10 mmol/L). The client is taking cholestyramine, and the nurse teaches the client about the medication. Which statement by the client indicates the need for further teaching? 1. "Constipation and bloating might be a problem." 2. "I'll continue to watch my diet and reduce my fats." 3. "Walking a mile each day will help the whole process." 4. "I'll continue my nicotinic acid from the health food store.

Answer: 4 Rationale: Nicotinic acid, even an over-the-counter form, should be avoided because it may lead to liver abnormalities. All lipid-lowering medications also can cause liver abnormalities, so a combination of nicotinic acid and cholestyramine resin needs to be avoided. Constipation and bloating are the 2 most common adverse effects. Walking and the reduction of fats in the diet are therapeutic measures to reduce cholesterol and triglyceride levels.

The nurse is conducting health screening for osteoporosis. Which client is at greatest risk of developing this problem? 1. A 25-year-old woman who runs 2. A 36-year-old man who has asthma 3. A 70-year-old man who consumes excess alcohol 4. A sedentary 65-year-old woman who smokes cigarettes

Answer: 4 Rationale: Risk factors for osteoporosis include female gender, being postmenopausal, advanced age, a low-calcium diet, excessive alcohol intake, being sedentary, and smoking cigarettes. Long-term use of corticosteroids, anticonvulsants, and/or furosemide also increases the risk

A client who is receiving digoxin daily has a serum potassium level of 3 mEq/L (3 mmol/L) and reports anorexia. The health care provider prescribes a serum digoxin level to be done. The nurse checks the results and should recognize which level that is outside of the therapeutic range? 1. 0.5 ng/mL (0.63 nmol/L) 2. 0.8 ng/mL (1.02 nmol/L) 3. 0.9 ng/mL (1.14 nmol/L) 4. 2.2 ng/mL (2.8 nmol/L)

Answer: 4 Rationale: The optimal therapeutic range for digoxin is 0.5 to 2.0 ng/mL (0.63 to 2.56 nmol/L). If the client is experiencing symptoms such as anorexia and is experiencing hypokalemia as evidenced by a low potassium level, digoxin toxicity is a concern. Therefore, option 4 is correct because it is outside of the therapeutic level and elevated.

A client with variant angina is scheduled to receive an oral calcium channel blocker twice daily. Which statement by the client indicates the need for further teaching? 1. "I should notify my cardiologist if my feet or legs start to swell." 2. "I am supposed to report to my cardiologist if my pulse rate decreases below 60." 3. "Avoiding grapefruit juice will definitely be a challenge for me, since I usually drink it every morning with breakfast." 4. "My spouse told me that since I have developed this problem, we are going to stop walking in the mall every morning."

Answer: 4 Rationale: Variant angina, or Prinzmetal's angina, is prolonged and severe and occurs at the same time each day, most often at rest. The pain is a result of coronary artery spasm. The treatment of choice is usually a calcium channel blocker, which relaxes and dilates the vascular smooth muscle, thus relieving the coronary artery spasm in variant angina. Adverse effects can include peripheral edema, hypotension, bradycardia, and heart failure. Grapefruit juice interacts with calcium channel blockers and should be avoided. If bradycardia occurs, the client should contact the primary health care provider or cardiologist. Clients should also be taught to change positions slowly to prevent orthostatic hypotension. Physical exertion does not cause this type of angina; therefore, the client should be able to continue morning walks with her or his spouse

The nurse creates a plan of care for a client with deep vein thrombosis. Which client position or activity in the plan should be included? 1. Out-of-bed activities as desired 2. Bed rest with the affected extremity kept flat 3. Bed rest with elevation of the affected extremity 4. Bed rest with the affected extremity in a dependent position

Rationale: For the client with deep vein thrombosis, elevation of the affected leg facilitates blood flow by the force of gravity and also decreases venous pressure, which in turn relieves edema and pain. A flat or dependent position of the leg would not achieve this goal. Bed rest is indicated to prevent emboli and to prevent pressure fluctuations in the venous system that occur with walking.
