Question 1 of 5
The nurse should assess a patient taking a drug with anticholinergic properties for inhibited function of the:
Correct Answer: A
Rationale: Step 1: Anticholinergic drugs block the action of acetylcholine in the body. Step 2: Acetylcholine is the neurotransmitter of the parasympathetic nervous system. Step 3: Inhibiting the function of acetylcholine affects the parasympathetic nervous system. Step 4: Therefore, the correct answer is A: parasympathetic nervous system. Summary: Choices B, C, and D are incorrect because anticholinergic drugs specifically target the parasympathetic nervous system, not the sympathetic, central, or peripheral nervous systems.
Question 2 of 5
A patient will be discharged with a 1-week supply of an opioid analgesic for pain management after abdominal surgery. The nurse will include which information in the teaching plan?
Correct Answer: C
Rationale: The correct answer is C: How to prevent constipation. Opioid analgesics commonly cause constipation as a side effect. Teaching the patient how to prevent constipation, such as increasing fiber intake and staying hydrated, is crucial for their overall well-being. This information will help the patient manage a common side effect of the medication and improve their quality of life post-surgery. Choice A is incorrect because dehydration due to diarrhea is not a common side effect of opioid analgesics. Choice B is incorrect because waiting for pain to become severe before taking the medication can lead to uncontrolled pain and poor pain management. Choice D is incorrect because taking the drug on an empty stomach is not typically necessary for opioid analgesics and may actually increase the risk of gastrointestinal side effects.
Question 3 of 5
A 38-year-old male patient stopped smoking 6 months ago. He tells the nurse that he still feels strong cigarette cravings and wonders if he is ever going to feel “normal” again. Which statement by the nurse is correct?
Correct Answer: B
Rationale: The correct answer is B: “These cravings may persist for several months.” This is correct because nicotine withdrawal symptoms, including cravings, can last for several months after quitting smoking. The patient's experience is common and does not indicate a permanent state. A: Incorrect. It is not accurate to say that cravings will never stop, as they typically decrease over time. C: Incorrect. Cravings do not necessarily mean the patient is still using nicotine but rather experiencing withdrawal symptoms. D: Incorrect. Cravings do not indicate that the patient is about to experience withdrawal but rather that they are still in the process of withdrawal.
Question 4 of 5
A 62-year-old man is to receive lidocaine as treatment for a symptomatic dysrhythmia. Upon assessment, the nurse notes that he has a history of alcoholism and has late-stage liver failure. The nurse will expect which adjustments to his drug therapy?
Correct Answer: A
Rationale: The correct answer is A: The dosage will be reduced by 50%. In this case, the patient has late-stage liver failure, which can impair the metabolism and clearance of lidocaine. Since lidocaine is metabolized in the liver, reducing the dosage by 50% will prevent potential toxicity due to impaired liver function. Incorrect Choices: B: Adding a diuretic to lidocaine is not indicated in this scenario as it does not address the issue of impaired liver function affecting lidocaine metabolism. C: Changing lidocaine to an oral dosage form does not address the issue of impaired liver function and may still lead to toxicity due to altered metabolism. D: Increasing the dosage of lidocaine would only increase the risk of toxicity in a patient with impaired liver function. It is important to reduce the dosage to prevent adverse effects.
Question 5 of 5
A patient is taking intravenous aminophylline for a severe exacerbation of chronic obstructive pulmonary disease. The nurse will assess for which therapeutic response?
Correct Answer: D
Rationale: The correct answer is D: Increased ease of breathing. Aminophylline is a bronchodilator used to improve breathing in COPD exacerbations. A therapeutic response would be improved ease of breathing due to bronchodilation. Increased sputum production (A) is not a desired effect. Increased heart rate (B) is a potential side effect of aminophylline, not a therapeutic response. Increased respiratory rate (C) may occur due to improved breathing but is not the primary therapeutic goal.
