ATI Pharmacology Practice A 2023 Questions
Question 1 of 5
Nurse Bryan knows that the age group that uses the most units of blood and blood products is:
Correct Answer: D
Rationale: The elderly above age 65 years are the largest consumers of blood and blood products due to the higher prevalence of chronic diseases, surgeries, and medical conditions that require transfusions, such as anemia, cancer, and cardiovascular diseases. While premature infants and children may require blood products, their overall usage is lower compared to the elderly population. Adults aged 21-64 also use blood products, but the demand is highest among the elderly due to their increased healthcare needs.
Question 2 of 5
A client is prescribed with Pentamidine (Pentam) IV for the treatment of Pneumocystis carinii
Correct Answer: D
Rationale: A sudden increase in temperature (fever) to 101.5°F in a client receiving Pentamidine IV for Pneumocystis carinii pneumonia would most likely indicate the client has developed another infection. This is because Pentamidine IV is an antibiotic used to treat Pneumocystis carinii pneumonia, and a new fever during treatment would suggest a new or persistent infection causing the elevated temperature. It is important for the nurse to assess the client further and consider additional diagnostic tests or treatments for the new infection while continuing to monitor and manage the initial condition for which Pentamidine was prescribed.
Question 3 of 5
A newly admitted client takes digoxin 0.25 mg/day. The nurse knows that which is the serum therapeutic range for digoxin?
Correct Answer: C
Rationale: The therapeutic range for serum digoxin levels is typically considered to be between 1.0 to 2.5 ng/mL. This range allows for optimal therapeutic effects while minimizing the risk of toxicity. Levels below 1.0 ng/mL may be subtherapeutic, while levels above 2.5 ng/mL may increase the risk of toxicity, leading to adverse effects such as arrhythmias, nausea, vomiting, and visual disturbances. Therefore, maintaining the digoxin level within the range of 1.0 to 2.5 ng/mL is crucial for safe and effective therapy.
Question 4 of 5
A 24-year-old sexually active woman presents to her primary care physician with vaginal itching and a greenish, frothy vaginal discharge. Her boyfriend is asymptomatic. She is prescribed metronidazole for Trichomonas vaginalis. Which of the following should be told to avoid while taking metronidazole?
Correct Answer: A
Rationale: Metronidazole treats Trichomonas vaginalis, and alcohol must be avoided. It inhibits aldehyde dehydrogenase, causing a disulfiram-like reaction (nausea, flushing). Aspirin , caffeine , grapefruit juice , and machinery (E) lack this interaction. This precaution prevents severe discomfort, ensuring treatment adherence.
Question 5 of 5
A 9-year-old boy is sent for neurologic evaluation because of episodes of apparent inattention. Over the past year, the child has experienced episodes during which he develops a blank look on his face and his eyes blink for 15 seconds. He immediately resumes his previous activity. Which one the following best describes this patient's seizures?
Correct Answer: D
Rationale: Absence seizures, typical in childhood, feature brief (10-20 second) lapses in awareness with staring and eye blinking, followed by immediate resumption of activity, as described. Simple partial seizures preserve consciousness with focal symptoms (e.g., twitching). Complex partial seizures impair awareness longer, with automatisms. Tonic-clonic seizures involve convulsions. Myoclonic seizures cause jerks without staring. The short duration, blank look, and rapid recovery align with absence seizures' EEG pattern (3 Hz spike-and-wave), distinguishing it here.
