Question 3 of 5
A nurse is caring for a patient who has excessive catecholamine release. Which assessment finding would the nurse correlate with this condition?
Correct Answer: B
Rationale: The correct answer is B: Increased pulse. Excessive catecholamine release, such as in a stress response, leads to sympathetic nervous system activation causing an increase in heart rate (pulse). This physiological response is known as the "fight or flight" response. Choices A, C, and D are incorrect as catecholamine release typically leads to increased blood pressure, increased respiratory rate, and decreased urine output due to vasoconstriction, increased oxygen demand, and fluid retention respectively.
Question 4 of 5
During surgery, we administer hexamethonium to an anesthetized patient. Which of the following effects should you expect in response to this drug?
Correct Answer: D
Rationale: The correct answer is D: Vasodilation. Hexamethonium is a ganglionic blocking agent that blocks nicotinic receptors in autonomic ganglia, leading to vasodilation due to inhibition of sympathetic vasoconstrictor tone. This causes a decrease in blood pressure. A: Bradycardia is not a direct effect of hexamethonium. B: Increased GI motility and defecation are not expected effects of hexamethonium. C: Increased salivary secretions are not directly affected by hexamethonium. In summary, the correct answer is D because hexamethonium causes vasodilation by blocking nicotinic receptors in autonomic ganglia, leading to a decrease in blood pressure.
Question 5 of 5
Intravenous administration of epinephrine to a patient results in a severe decrease in diastolic pressure and an increase in cardiac output. Which of the following drugs might the patient have previously taken that could account for this unexpected effect?
Correct Answer: D
Rationale: The correct answer is D: Prazosin. Prazosin is an alpha-1 adrenergic receptor antagonist, which blocks the vasoconstrictor effect of catecholamines like epinephrine, leading to vasodilation and a decrease in diastolic pressure. The unexpected effect of a decrease in diastolic pressure and an increase in cardiac output after epinephrine administration suggests that the patient might have taken a drug that blocks alpha-1 receptors. Propranolol (A) is a beta-blocker, which would not cause this effect. Atropine (B) is a muscarinic receptor antagonist and would not explain the observed effects. Phenylephrine (C) is an alpha-1 agonist, so it would not result in the described response. Therefore, Prazosin (D) is the most likely drug the patient previously took to account for the unexpected effects of epinephrine administration.
