Question 1 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 2 of 5
The nurse has completed medication education with the patient who is receiving risperidone (Risperdal). The nurse evaluates that the education has been effective when the patient makes which statement?
Correct Answer: B
Rationale: Risperidone risks agranulocytosis, requiring blood monitoring . This statement shows understanding of a critical safety step, indicating effective education. Nightmares , weight loss , and metallic taste aren't key concerns. B ensures safety, making it the best indicator.
Question 3 of 5
The patient has a potassium level of 5.9 mEq/L. The nurse is administering glucose and insulin. The patient's wife says, 'He doesn't have diabetes, why is he getting insulin?' What is the best response by the nurse?
Correct Answer: A
Rationale: Hyperkalemia (potassium 5.9 mEq/L) is treated emergently with glucose and insulin, which drive potassium into cells, temporarily lowering serum levels . Insulin facilitates this shift by enhancing cellular uptake, paired with glucose to prevent hypoglycemia—accurate and clear for the wife.
Choice B misstates that potassium is excreted via blood sugar; it's redistributed, not eliminated.
Choice C compares insulin to Kayexalate (which binds potassium in the gut), but safety isn't the primary rationale.
Choice D incorrectly suggests renal excretion, which isn't insulin's role (diuretics or dialysis do that).
Choice A explains the mechanism correctly, addressing the wife's confusion with scientific clarity.
Question 4 of 5
While assessing a patient who is taking a beta blocker for angina, the nurse knows to monitor for which adverse effect?
Correct Answer: C
Rationale: Beta blockers are medications commonly used to treat angina by reducing the heart's workload and oxygen demand. One common side effect of beta blockers is bradycardia, which is a slower than normal heart rate. Since beta blockers work by blocking the effects of adrenaline on the heart, they can slow down the heart rate. It is important for the nurse to monitor the patient for signs and symptoms of bradycardia, such as fatigue, dizziness, and confusion, especially when assessing a patient taking beta blockers for angina.
Question 5 of 5
What is the e昀昀ect of Beta Blockers?
Correct Answer: C
Rationale: The effect of Beta Blockers is to decrease blood pressure and heart rate. Beta blockers work by blocking the action of adrenaline on beta receptors, leading to decreased heart rate and reduced force of contraction of the heart muscle. This results in a lowering of blood pressure, making beta blockers commonly prescribed for conditions such as hypertension, angina, and heart failure. Additionally, beta blockers are also used to manage certain arrhythmias and prevent heart attacks.
Therefore, the correct answer is C - Decreases blood pressure and heart rate.
