ATI Pharmacology Proctored Exam 2023 Quizlet
1. Which of the following is a potassium-sparing diuretic?
- A. Furosemide
- B. Spironolactone
- C. Hydrochlorothiazide
- D. Bumetanide
Correct answer: B
Rationale: Spironolactone is classified as a potassium-sparing diuretic. It works by antagonizing the aldosterone receptor, leading to potassium retention and sodium excretion. This mechanism makes it a suitable choice for conditions where potassium retention is desired, such as in patients with heart failure or liver cirrhosis. Choices A, C, and D are not potassium-sparing diuretics. Furosemide, hydrochlorothiazide, and bumetanide are loop diuretics and thiazide diuretics, respectively, which promote the excretion of potassium.
2. A client reports taking Phenylephrine nasal drops for the past 10 days for Sinusitis. The nurse should assess the client for which of the following adverse effects of this medication?
- A. Sedation
- B. Nasal congestion
- C. Productive cough
- D. Constipation
Correct answer: B
Rationale: The correct answer is B: Nasal congestion. When used for more than 5 days, nasal sympathomimetic medications like phenylephrine can lead to rebound nasal congestion, which is an adverse effect to be assessed in the client. Sedation (choice A) is not a common adverse effect of phenylephrine. Productive cough (choice C) and constipation (choice D) are also not typical adverse effects associated with phenylephrine use.
3. A patient has been taking hydrocodone, an opioid analgesic for their moderate pain, and they have taken more than the prescribed dose. What should you administer as the antidote if they experience toxicity?
- A. Naloxone
- B. N-acetylcysteine
- C. Atropine
- D. Digoxin immune Fab
Correct answer: A
Rationale: Naloxone is the specific antidote for opioid toxicity. It works by blocking the effects of opioids on the central nervous system, thereby reversing symptoms like respiratory depression and sedation. N-acetylcysteine is used for acetaminophen overdose, while atropine is indicated for certain types of poisonings. Digoxin immune Fab is used for digoxin toxicity. Therefore, in the case of opioid toxicity due to hydrocodone overdose, naloxone is the appropriate antidote.
4. A client has been prescribed a Beta Blocker for hypertension. Which of the following findings should the nurse monitor as an adverse effect of this medication?
- A. Bradycardia
- B. Hypertension
- C. Hyperglycemia
- D. Hypernatremia
Correct answer: A
Rationale: Bradycardia is the correct answer. Beta Blockers work by slowing down the heart rate, which can lead to bradycardia as an adverse effect. Monitoring for bradycardia is essential to prevent complications. Choices B, C, and D are incorrect because Beta Blockers do not typically cause hypertension, hyperglycemia, or hypernatremia as adverse effects.
5. A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?
- A. One
- B. Two
- C. Three
- D. Four
Correct answer: A
Rationale: Phenobarbital, with a long half-life of 4 days, remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should administer phenobarbital once a day to maintain a consistent therapeutic effect without the need for multiple daily doses. Administering the medication more than once a day would not be necessary and could increase the risk of side effects or toxicity. Therefore, the correct answer is to administer phenobarbital once a day.
