Question 1 of 5
Before administering a client's prescribed nonselective adrenergic blocker, what should the nurse assess?
Correct Answer: B
Rationale: The correct answer is B: Pulse and blood pressure. Before administering a nonselective adrenergic blocker, assessing the client's pulse and blood pressure is crucial. Adrenergic blockers affect the sympathetic nervous system, leading to potential decreases in heart rate and blood pressure. Monitoring these vital signs helps detect any adverse effects or contraindications to administering the medication. Assessing WBC count (
A), bowel sounds (
C), and serum sodium and potassium levels (
D) are not directly related to the action or potential side effects of adrenergic blockers.
Question 2 of 5
The drug nalbuphine is an agonist-antagonist (partial agonist). The nurse understands that which is a characteristic of partial agonists?
Correct Answer: A
Rationale: The correct answer is A: They have a lower dependency potential than agonists. Partial agonists like nalbuphine have a ceiling effect, meaning their effects plateau even with increased doses, reducing the risk of dependency compared to full agonists.
Choice B is incorrect because potency is not necessarily higher in partial agonists.
Choice C is incorrect because not all partial agonists have anti-inflammatory effects.
Choice D is incorrect as partial agonists are not typically used to reverse opiates.
Question 3 of 5
A school-aged child is brought to the clinic by her parents. The parents state that the child will be engaged in some activity at home and then will just stop suddenly for a few seconds and then pick up the activity again as if there had been no break in what she was doing. This child should be assessed for what neurological disorder?
Correct Answer: B
Rationale: The correct answer is B: Absence seizures. Absence seizures are characterized by a brief lapse in awareness or consciousness, often lasting only a few seconds, where the individual appears to stare blankly. This matches the description given by the parents of the child stopping suddenly for a few seconds during an activity. Myoclonic seizures (
A) involve sudden, brief muscle jerks, not just a pause in activity. Status epilepticus (
C) is a continuous seizure lasting more than 5 minutes or multiple seizures without regaining consciousness.
Tonic-clonic seizures (
D) involve loss of consciousness, muscle rigidity, and convulsions, which are not described in the scenario.
Question 4 of 5
A nurse is preparing to administer amantadine 150 mg PO every 12 hr. Available is amantadine 50 mg/5 mL syrup. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate the mL per dose, we need to first determine the total dose required per dose. The total dose is 150 mg and since the syrup is 50 mg/5mL, we can set up a proportion: 150 mg/x mL = 50 mg/5 mL. Solving for x gives x = 15 mL.
Therefore, the nurse should administer 15 mL per dose. Other choices are incorrect because they do not accurately calculate the mL per dose based on the given information.
Choice B, 10 mL, would be too low, choice C, 12 mL, would also be too low, and choice D, 18 mL, would be too high based on the calculation.
Choice A is the correct answer as it accurately calculates the mL per dose required.
Question 5 of 5
The nurse is reviewing the use of central nervous system stimulants. Which of these are indications for this class of drugs? (Select all that apply.)
Correct Answer: A,C,E
Rationale: The correct answers are A, C, and E. A: ADHD is treated with CNS stimulants to improve focus and impulse control. C: Narcolepsy is managed with stimulants to reduce excessive daytime sleepiness. E: Obesity can be treated with stimulant medications to suppress appetite and increase metabolism. B: Panic attacks are not typically treated with stimulants but with anxiolytics. D: Neonatal apnea is a respiratory condition and not an indication for CNS stimulants.
