MED 143 ADRENERGIC BLOCKING ANTAGONISTS – CHAPTER 31 QUESTIONS AND ANSWERS VERIFIED 2023

MED 143 ADRENERGIC BLOCKING ANTAGONISTS – CHAPTER 31 QUESTIONS AND ANSWERS VERIFIED 2023. A nurse is working with a patient who is taking an adrenergic blocking agent. While assessing the patient's medication history, the nurse discovers that the patient takes several alternative therapies. What herb is the nurse concerned may interact with the adrenergic blocking agent and affect the patient's blood glucose level? A) Ginseng B) Nightshade C) Di huang D) Saw Palmetto Ans: C Feedback: Di huang is an alternative therapy that can lower blood glucose when used in combination with adrenergic blocking agents. Ginseng increases antihypertensive effects; nightshade slows the heart rate; and saw palmetto increases the risk of urinary tract complications when used in combination with adrenergic blocking agents. 4.A priority nursing assessment for a patient who is to receive an alpha- or beta-adrenergic blocking agent would be what? Page 1 A) Monitoring respiratory rate B) Checking blood glucose level C) Measuring urine output D) Assessing heart rate Ans: D Feedback: The most serious adverse effect would be severe bradycardia, so the nurse's priority would be assessing the heart rate. If the patient were identified as having diabetes, then monitoring blood glucose levels would become important because these drugs can aggravate diabetes by blocking sympathetic response including masking the usual signs and symptoms of hypoglycemia and hyperglycemia. Respiratory rate could be impacted if the patient was identified as having a condition causing bronchospasm and diabetes because the combination could worsen both conditions. Measuring urine output should be part of the patient's care, but it is not the priority assessment. 5.Bisoprolol (Zebeta) would be the drug of choice for which patient with a diagnosis of hypertension? A) A 7-year-old patient B) A 15-year-old patient C) A 37-year-old patient D) A 69-year-old patient Ans: D Feedback: Bisoprolol is the drug of choice for older adults. It is not associated with as many adverse effects in the elderly and regular dosing profiles can be used. This drug does not have an established pediatric dosage. Although the 37-year-old patient is an adult, there are additional choices for this patient, with a more favorable adverse effect profile. 6.What would be the teaching priority for a diabetic patient being treated with a nonselective beta-blocker? A) To take his own pulse B) To weigh himself once a week at the same time of day C) To avoid smoke-filled rooms D) To understand signs and symptoms of hypo- or hyperglycemic reaction Ans: D Feedback: Because the beta-blockers stop the signs and symptoms of a sympathetic stress reaction, the signs and symptoms associated with hypo- or hyperglycemia, the diabetic patient taking a beta-blocker will need to understand this and learn new indicators of these reactions. Taking his pulse, weekly weighing, and avoiding smoke-filled rooms are good health practices and should be done, but not specifically needed by a diabetic patient taking a beta-blocker.
