Question 1 of 5
The mother of a 7-year-old child says to the nurse, 'My child is distractible in school, cannot complete assignments on time, and interrupts other children while they are speaking. What do you think?' What is the best response by the nurse?
Correct Answer: C
Rationale: Distractibility, incomplete tasks, and interrupting suggest ADHD-hyperactivity/impulsivity, per DSM-5-warranting evaluation. Depression may show withdrawal, not this. Bipolar needs mania evidence, not here. Typical 7-year-olds vary, but this exceeds norms. ADHD fits, prompting testing.
Question 2 of 5
Drug X has a median lethal dose of 30 mg and a median effective dose of 10. Drug Y has a therapeutic index of 4, while drug Z has a therapeutic index of 3. Which statement is accurate based on this information?
Correct Answer: C
Rationale: Therapeutic index (TI) = lethal dose (LD50) / effective dose (ED50). Drug X: 30/10 = 3. Drug Y: TI = 4. Drug Z: TI = 3. Higher TI means safer-Drug Y (4) tops X and Z (3), balancing efficacy and toxicity best. X and Y aren't both safer-X matches Z. X's TI isn't 20. Z isn't safest. Y's TI makes it safest.
Question 3 of 5
The following drugs must be avoided in severe renal failure (GFR ≤10 mL/min):
Correct Answer: D
Rationale: Metformin is contraindicated in severe renal failure due to the risk of lactic acidosis, a rare but potentially fatal side effect.
Question 4 of 5
Samuel, a 65-year-old patient comes into the hospital for an anginal attack. Which of the following is an important nursing intervention when administering Nitroglycerine?
Correct Answer: C
Rationale: It is important to remove the transdermal Nitroglycerine patch for 10-12 hours every night to prevent the development of tolerance. Tolerance can occur when the body becomes less responsive to the medication over time, reducing its effectiveness. By allowing a break in Nitroglycerine administration overnight, tolerance development can be minimized, ensuring the medication remains effective for the patient when needed. This nursing intervention helps to maintain the efficacy of Nitroglycerine in managing anginal attacks for the patient.
Question 5 of 5
The nurse is giving intravenous nitroglycerin to a patient who has just been admitted because of an acute myocardial infarction. Which statement is true regarding the administration of the intravenous form of this medication?
Correct Answer: D
Rationale: Intravenous nitroglycerin is commonly administered in infusions along with other medications, such as heparin and morphine, to manage acute myocardial infarction. By giving it in infusions, healthcare providers can control the dosage and titrate it to the patient's response while also minimizing the risk of sudden drops in blood pressure. Additionally, administering nitroglycerin in infusions allows for precise and continuous delivery of the medication to achieve the desired therapeutic effect.
