ATI Pharmacology Proctored Exam 2019
1. A healthcare professional in an emergency unit is reviewing the medical record of a client who is being evaluated for angle-closure glaucoma. Which of the following findings is indicative of this condition?
- A. Insidious onset of painless loss of vision
- B. Gradual reduction in peripheral vision
- C. Severe pain around the eyes
- D. Intraocular pressure 12 mm Hg
Correct answer: C
Rationale: Severe pain around the eyes that radiates over the face is a classic symptom of acute angle-closure glaucoma. This intense pain is often associated with other symptoms such as blurred vision, halos around lights, redness in the eye, and sometimes nausea and vomiting. Immediate medical attention is required to prevent permanent vision loss. Choices A, B, and D are incorrect. Insidious onset of painless loss of vision is more indicative of conditions like macular degeneration. Gradual reduction in peripheral vision is commonly seen in conditions like open-angle glaucoma. An intraocular pressure of 12 mm Hg is within the normal range and is not typical of angle-closure glaucoma.
2. A client who received Prochlorperazine 4 hours ago reports spasms of his face. The nurse should anticipate a prescription for which of the following medications?
- A. Fomepizole
- B. Naloxone
- C. Phytonadione
- D. Diphenhydramine
Correct answer: D
Rationale: The client's symptoms of face spasms after receiving Prochlorperazine indicate acute dystonia, a known side effect. Diphenhydramine is commonly administered to manage extrapyramidal symptoms, such as muscle spasms, caused by medications like Prochlorperazine. Therefore, the nurse should anticipate a prescription for Diphenhydramine to alleviate the client's symptoms. Choices A, B, and C are incorrect because Fomepizole is used in methanol or ethylene glycol poisoning, Naloxone is an opioid antagonist used in opioid overdose, and Phytonadione is vitamin K, used to reverse the effects of certain blood thinners.
3. To which pharmacologic classification does the drug propranolol belong?
- A. Beta Blockers
- B. Cholinergics
- C. Immune globulins
- D. Barbiturates
Correct answer: A
Rationale: Propranolol belongs to the pharmacologic classification of Beta Blockers. Beta blockers work by blocking the action of adrenaline and other stress hormones on beta-adrenergic receptors. They are commonly used to manage conditions like high blood pressure, angina, and arrhythmias. Choice B, Cholinergics, is incorrect because cholinergics work by stimulating the parasympathetic nervous system, unlike beta blockers that block adrenergic receptors. Choice C, Immune globulins, is incorrect as it refers to antibodies used to boost the immune system, not the mechanism of action of propranolol. Choice D, Barbiturates, is incorrect as barbiturates are a different class of drugs that act as central nervous system depressants, primarily used as sedatives and anesthetics.
4. A client is receiving Morphine IV for pain management. Which of the following actions should the nurse take?
- A. Monitor the client's respiratory rate every 15 minutes.
- B. Monitor the client's blood pressure every 30 minutes.
- C. Monitor the client's oxygen saturation every hour.
- D. Monitor the client's heart rate every 5 minutes.
Correct answer: A
Rationale: The correct action for the nurse is to monitor the client's respiratory rate every 15 minutes while on Morphine IV to promptly detect respiratory depression, a critical adverse effect associated with this medication. Respiratory depression is a common side effect of opioid medications like Morphine and can be life-threatening. Monitoring the respiratory rate frequently enables the nurse to identify early signs of respiratory compromise and intervene promptly. Monitoring other vital signs like blood pressure, oxygen saturation, or heart rate is important but not as crucial as monitoring respiratory rate when a client is on Morphine IV.
5. A client with brain cancer and headaches is prescribed dexamethasone. What is the purpose of this adjuvant medication?
- A. To decrease inflammation and swelling
- B. To improve concentration
- C. To induce sedation
- D. To treat depression
Correct answer: A
Rationale: Dexamethasone, a glucocorticoid, is indicated for clients with brain cancer to decrease inflammation and swelling. It helps reduce cerebral edema and relieve pressure caused by the tumor, ultimately alleviating headaches. The purpose of prescribing dexamethasone in this case is not to improve concentration (choice B), induce sedation (choice C), or treat depression (choice D). Methylphenidate, a stimulant, is used for conditions like ADHD, not for brain cancer. Hydroxyzine, an antihistamine, is primarily used for anxiety and itching, not for brain cancer. Amitriptyline, a tricyclic antidepressant, is used for conditions like depression and neuropathic pain, not specifically for brain cancer-related headaches.
