ATI Proctored Pharmacology Test

Correct Answer: A

Rationale: Clients prescribed Digoxin should monitor their heart rate before each dose. This is essential to identify any potential bradycardia, defined as a heart rate below 60 bpm, which can be a side effect of Digoxin. Any significant changes in heart rate should be reported promptly to the healthcare provider for further evaluation and management. Choice B is incorrect because increasing intake of high-potassium foods can lead to hyperkalemia, a condition that can be exacerbated by Digoxin. Choice C is incorrect as taking Digoxin with a full glass of milk is not necessary. Choice D is incorrect as black, tarry stools are not an expected side effect of Digoxin.

Correct Answer: A

Rationale: The correct answer is A: Ondansetron. Ondansetron is a commonly used antiemetic for managing nausea and vomiting in clients undergoing chemotherapy. It works by blocking serotonin to reduce these symptoms effectively. Metoclopramide (choice B) is another antiemetic but is more commonly used for gastric motility disorders. Promethazine (choice C) is an antihistamine with antiemetic properties, but ondansetron is often preferred for chemotherapy-induced nausea and vomiting due to its efficacy and fewer side effects. Lorazepam (choice D) is a benzodiazepine used for anxiety and insomnia, not typically for managing nausea and vomiting in this context.

Correct Answer: C

Rationale: In treating a Cerebrospinal fluid infection caused by gram-negative bacteria, Cefepime, a fourth-generation cephalosporin, is the most suitable choice due to its enhanced efficacy against gram-negative organisms in such infections. Cefaclor (Choice A) is a second-generation cephalosporin more commonly used for respiratory tract infections. Cefazolin (Choice B) is a first-generation cephalosporin often used for skin and soft tissue infections. Cephalexin (Choice D) is a first-generation cephalosporin indicated for skin and urinary tract infections, but not the optimal choice for a Cerebrospinal fluid infection with gram-negative bacteria.

Correct Answer: A

Rationale: The nurse should monitor the client's potassium levels when taking Furosemide because the medication can lead to hypokalemia. Hypokalemia is a potential side effect of Furosemide, a loop diuretic, due to increased potassium excretion in the urine. Monitoring potassium levels is crucial to prevent complications such as cardiac dysrhythmias associated with low potassium levels. Therefore, choices B (Sodium level), C (Hemoglobin A1C), and D (BUN) are incorrect as they are not directly influenced by Furosemide therapy for heart failure.

Correct Answer: A

Rationale: Sildenafil is contraindicated with nitrates like isosorbide due to the risk of severe hypotension. Isosorbide is a nitrate that can potentiate the hypotensive effects of sildenafil, leading to a dangerous drop in blood pressure. Therefore, it is essential to avoid concurrent use of isosorbide and sildenafil to prevent adverse effects. Phenytoin, metronidazole, and prednisone do not have significant interactions with sildenafil and are not contraindicated when used together.
