Question 3 of 5
The nurse is teaching assistive personnel (AP) about hormones that are produced by the adrenal glands. Which hormone has the primary responsibility of maintaining fluid volume and electrolyte composition?
Correct Answer: C
Rationale: The correct answer is C: Aldosterone. Aldosterone is a hormone produced by the adrenal glands that plays a crucial role in maintaining fluid volume and electrolyte composition by regulating sodium and potassium levels in the body. It promotes sodium reabsorption and potassium excretion in the kidneys, helping to maintain blood pressure and electrolyte balance. Therefore, aldosterone has the primary responsibility for maintaining fluid volume and electrolyte composition. A: Sodium - While sodium is an important electrolyte involved in fluid balance, it is not a hormone produced by the adrenal glands. B: Magnesium - Magnesium is also an important electrolyte, but it is not primarily responsible for maintaining fluid volume and electrolyte composition in the body. D: Renin - Renin is an enzyme produced by the kidneys that plays a role in regulating blood pressure and fluid balance, but it is not a hormone produced by the adrenal glands and does not have the primary responsibility for maintaining fluid volume and electrolyte composition.
Question 4 of 5
A patient presents with food poisoning that is attributed to botulism (Botulinum toxin poisoning). Which of the following is a correct characteristic, finding, or mechanism associated with this toxin?
Correct Answer: A
Rationale: The correct answer is A: Complete failure of all cholinergic neurotransmission. Botulinum toxin inhibits acetylcholine release at neuromuscular junctions, leading to complete failure of all cholinergic neurotransmission. This results in flaccid paralysis and characteristic symptoms of botulism. Choice B is incorrect because pralidoxime is used to treat organophosphate poisoning, not botulism. Choice C is incorrect as botulinum toxin affects both parasympathetic and sympathetic nervous systems. Choice D is incorrect as botulinum toxin does not cause overstimulation but rather inhibits neurotransmission.
Question 5 of 5
Drug X causes an increase in blood pressure and a decrease in heart rate when administered to a patient intravenously. If an antagonist at ganglionic nicotinic receptors is administered first, drug X causes an increase in blood pressure and an increase in heart rate. Drug X most likely is
Correct Answer: B
Rationale: The correct answer is B: Norepinephrine. When an antagonist at ganglionic nicotinic receptors is administered, it blocks the inhibitory effect on sympathetic tone. Since norepinephrine is a sympathetic neurotransmitter that increases blood pressure and heart rate, it is likely that Drug X is norepinephrine. Propranolol (A) is a beta-blocker that decreases heart rate, Isoproterenol (C) is a beta-agonist that increases heart rate, and Terbutaline (D) is a beta-agonist that also increases heart rate. These choices do not align with the observed effects of Drug X when the ganglionic nicotinic receptor antagonist is administered.
