are narcotics that would not be used with lorazepam because the combinations may depress respiratory drive, create severe hypotension or bradycardia, and substantially alter level of consciousness.Question 261 out of 1 pointsA nurse who provides care on an acute medicine unit has frequently recommended the use of nicotine replacement gum for patients who express a willingness to quit smoking during their admission or following their discharge. For which of the following patients would nicotine gum be contraindicated?
Response Feedback:Nicotine in any dosage form should not be used in patients immediately after myocardial infarction, or in those with life-threateningarrhythmias or severe or worsening angina pectoris. Antibiotics, anticoagulants, and renal failure are not contraindications for the use of nicotine as an aid to smoking cessation.Question 271 out of 1 pointsA patient has been prescribed lithium therapy. Which of the following signs and symptoms will the nurse tell the patient to report immediately?Response Feedback:Muscle twitching is an early symptom of lithium toxicity and should be reported immediately. Muscle twitching indicates that a dosage change may be needed. Increased thirst and urination are acute effects of lithium, whereas hair loss is a chronic adverse effect.Question 281 out of 1 pointsWhich of the following would be an expected outcome in a patient who has been given atropine during a medical emergency?Response Feedback:Atropine is used to help restore normal sinus rhythm in emergency situations, such as symptomatic bradycardia, pulseless electrical activity, ventricular asystole, or cardiopulmonary resuscitation. It does not resolve acid-based imbalances or decreased level of consciousness and atropine increases, rather than decreases, blood pressure.Question 291 out of 1 pointsA nurse is caring for a patient who has been admitted with acute cocaine intoxication.Which of the following vital signs would the nurse expect to find initially when assessing the patient?Response Feedback:CNS stimulants like cocaine initially increase heart rate and blood pressure. Cocaine impairs the uptake of norepinephrine and epinephrine by presynaptic nerve endings, thus activating the adrenergic systems and causing hypertension, tachycardia, and vasoconstriction.Question 301 out of 1 pointsA nurse is providing care for a patient who suffered extensive burns to his extremitiesduring a recent industrial accident. Topical lidocaine gel has been ordered to be applied to the surfaces of all his burns in order to achieve adequate pain control. When considering this order, the nurse should be aware thatResponse Applying lidocaine preparations to severely traumatized mucosa (large
Feedback:skin abrasions, eczema, and burns) can increase its absorption, whichin turn increases the risk of systemic toxicity. Intravenous lidocaine is not normally used for analgesia. The destruction of nerve endings in a burn site does not mitigate the need for topical pain control and lidocaine does not need to be potentiated with another anesthetic.
