Question 1 of 5
A 44-year-old man is found dead in his home by the police. Reports indicate that the man was heating his one-room apartment with a kerosene space heater. He was found because other people in the apartment complex that he lives at developed headache, lethargy, and confusion. What is the most likely explanation for these findings?
Correct Answer: A
Rationale: Kerosene heater use causing death and symptoms (headache, lethargy) points to carbon monoxide poisoning . CO binds hemoglobin, causing hypoxia. Pneumonia , cyanide , and silica don't fit. CO's silent lethality explains the scenario.
Question 2 of 5
An adolescent client will receive Depo-Provera as a method of birth control. She asks the nurse how long the drug will be effective. What is the best response by the nurse?
Correct Answer: D
Rationale: Depo-Provera lasts 3 months , inhibiting ovulation via progestin. Two months underestimates, six months and one year overestimate. D provides accurate timing, ensuring adherence, making it the best response.
Question 3 of 5
A patient with a new prescription for a HMG-CoA (statin) drug is instructed to take the
Correct Answer: D
Rationale: The nurse's best response is D: "This timeframe correlates better with the natural diurnal rhythm of cholesterol production." This explanation is accurate and helps the patient understand the rationale behind the timing of taking the HMG-CoA (statin) drug. Cholesterol production in the body typically follows a natural diurnal rhythm, with cholesterol synthesis peaking during the night. By taking the statin medication in the evening, it aligns with the body's cholesterol production pattern, making it more effective in reducing cholesterol levels. This explanation supports the patient's understanding of the importance of timing in maximizing the medication's effectiveness.
Question 4 of 5
Drug action that increase body activity
Correct Answer: A
Rationale: Stimulants are drugs that increase the body's activity levels. They work on the central nervous system to enhance alertness, attention, and energy. Examples of stimulants include caffeine, amphetamines, and nicotine. Stimulants can increase heart rate, blood pressure, and metabolism, leading to heightened physical and mental activity.
Question 5 of 5
Upon preparing to administer activated charcoal by mouth to treat a patient who took an overdose of aspirin and several unknown drugs, the nurse notes that the patient has become very somnolent and eyes open only to a noxious stimulus. Which action by the nurse is most appropriate at this point?
Correct Answer: A
Rationale: The patient's decreased level of consciousness (somnolence and only responding to noxious stimuli) indicates a potential deterioration in their condition, possibly due to the overdose. Activated charcoal is contraindicated in patients with an altered mental status due to the risk of aspiration. The nurse should immediately consult the nurse practitioner to reassess the patient's condition and determine the appropriate intervention, such as securing the airway or considering alternative treatments.
