ATI Pharmacology Proctored Exam

Correct Answer: C

Rationale: Yellow-tinged vision, along with nausea, vomiting, and confusion, are common manifestations of Digoxin toxicity. Visual disturbances are important to recognize as they can indicate the need for immediate medical attention and potential adjustment of Digoxin therapy to prevent serious complications. Elevated blood pressure is not typically associated with Digoxin toxicity; instead, hypotension may occur. Bradycardia is a common therapeutic effect of Digoxin rather than a sign of toxicity. Ringing in the ears, or tinnitus, is also a potential side effect of Digoxin but is less specific to toxicity compared to yellow-tinged vision.

Correct Answer: D

Rationale: The healthcare professional should prioritize assessing the client's respiratory rate because respiratory depression is a life-threatening adverse effect of Morphine. Monitoring the respiratory rate allows for early detection of potential complications and timely intervention to prevent harm. Assessing urine output, bowel sounds, and pain level are important but should come after ensuring the client's respiratory status is stable as it is the most critical assessment to prevent serious complications associated with opioid use.

Correct Answer: A

Rationale: Dexamethasone, a glucocorticoid, is indicated for clients with brain cancer experiencing headaches as it decreases inflammation and swelling. It is commonly used to reduce cerebral edema and relieve pressure caused by the tumor. Methylphenidate (Choice B) is a central nervous system stimulant used in conditions like ADHD and narcolepsy, not for brain cancer headaches. Hydroxyzine (Choice C) is an antihistamine used for anxiety and allergic conditions, not indicated for brain cancer headaches. Amitriptyline (Choice D) is a tricyclic antidepressant used for depression, neuropathic pain, and migraine prophylaxis, but not typically indicated for brain cancer headaches.

Correct Answer: A

Rationale: Phenobarbital has a long half-life of 4 days, meaning it remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should expect to administer phenobarbital once a day to maintain therapeutic levels and effectiveness. Administering it more than once a day would lead to unnecessary dosing and potential adverse effects as the medication remains active in the body for an extended period.

Correct Answer: D

Rationale: The correct answer is to monitor for signs of dehydration. Hydrochlorothiazide is a diuretic that can lead to fluid loss and electrolyte imbalance, potentially causing dehydration. Signs of dehydration include dry mouth, increased thirst, and decreased urine output. It is important for the client to be vigilant in monitoring and reporting these symptoms to healthcare providers to prevent complications. Choices A, B, and C are incorrect because taking the medication in the morning, increasing potassium-rich foods, or taking the medication with food are not specific instructions related to the potential side effects of Hydrochlorothiazide.
