ATI Pharmacology Proctored Exam 2019 Quizlet Questions
Question 1 of 5
The nurse teaches a class about medication used during pregnancy to pregnant women. The nurse determines that additional instruction is required when a class participant makes which response?
Correct Answer: A
Rationale: Drugs harm fetuses across trimesters-first (organogenesis) is critical, but later effects (e.g., growth) occur, so this needs correction. Avoiding OTC drugs is wise-many risk harm. Teratogens cause death or defects, true. Breast milk transfers drugs, also true. First-trimester-only harm misstates risk, requiring reteaching.
Question 2 of 5
A patient is taking digoxin (Lanoxin) and a loop diuretic daily. When the nurse enters the room with the morning medications, the patient states, I am seeing a funny yellow color around the lights. What is the nurse™s next action?
Correct Answer: A
Rationale: The patient's statement about seeing a funny yellow color around the lights could be an early sign of digoxin toxicity. Digoxin toxicity can cause visual disturbances, such as seeing yellow or green halos around lights. Therefore, the nurse's next action should be to assess the patient for other symptoms of digoxin toxicity to determine the need for further intervention or medical attention.
Question 3 of 5
A 22-year-old woman ingests an entire bottle of acetaminophen in an attempted suicide. She unexpectedly feels well; and when her boyfriend discovers what she has done, he takes her to the emergency department. Which of the following drugs should be given in the ER?
Correct Answer: B
Rationale: Acetaminophen overdose needs acetylcysteine , replenishing glutathione to detoxify NAPQI, preventing liver damage. Aspirin , bicarbonate , fomepizole , and penicillamine (E) don't apply. Early administration reverses her silent toxicity.
Question 4 of 5
A female client who has a history of seizures went to a healthcare facility to ask the nurse regarding the use of birth control pills while on phenytoin therapy. The nurse correctly states to the client that:
Correct Answer: A
Rationale: Phenytoin induces liver enzymes that increase the metabolism of oral contraceptives, reducing their effectiveness. This increases the risk of unintended pregnancy. Pregnancy is not prohibited, but effective contraception is essential. Discontinuing phenytoin is not recommended without medical advice. Therefore, the nurse should inform the client about the decreased effectiveness of birth control pills.
Question 5 of 5
Modest improvement in the memory of patients with Alzheimer's disease may occur with drugs that increase transmission at which of the following receptors?
Correct Answer: B
Rationale: Alzheimer's disease features cholinergic neuron loss, impairing memory via reduced acetylcholine signaling in the hippocampus and cortex. Drugs like acetylcholinesterase inhibitors (e.g., donepezil) boost cholinergic transmission by preventing acetylcholine breakdown, modestly improving memory and cognition in early stages. Adrenergic enhancement (e.g., via norepinephrine) affects arousal, not memory directly. Dopaminergic drugs treat Parkinson's, not Alzheimer's cognitive deficits. GABAergic drugs (e.g., benzodiazepines) inhibit cognition, worsening memory. Serotonergic agents target mood, not memory. The cholinergic deficit is a hallmark of Alzheimer's pathology, and augmenting this system remains a primary therapeutic strategy, validated by clinical outcomes.
