Question 1 of 5
Laboratory results show a patient’s lithium level is 1.0 mEq/L. Select the correct analysis.
Correct Answer: A
Rationale: The correct answer is A: Within therapeutic limits. A lithium level of 1.0 mEq/L falls within the therapeutic range of 0.6-1.2 mEq/L for maintenance therapy. This level indicates that the patient's lithium concentration is at an appropriate and effective level for managing their condition. - B: Below therapeutic limits is incorrect as the patient's lithium level is actually within the therapeutic range. - C: Above therapeutic limits is incorrect as the patient's lithium level is not elevated but rather within the therapeutic range. - D: Incorrect. Lithium levels are reported as mEq/dL is incorrect as the standard unit for reporting lithium levels is mEq/L, not mEq/dL.
Question 2 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 3 of 5
In order to accurately predict how the body absorbs, distributes, metabolizes, and eliminates psychotropic medications the nurse must be familiar with a medication’s:
Correct Answer: C
Rationale: Rationale for Correct Answer (C - Pharmacokinetics): 1. Pharmacokinetics refers to how the body processes a medication including absorption, distribution, metabolism, and elimination. 2. Understanding pharmacokinetics helps predict how a medication will act in the body. 3. It is crucial for determining dosing intervals, potential drug interactions, and individualized therapy. 4. Half-life (A) is only one component of pharmacokinetics, not encompassing the full picture. 5. Side effects (B) are important but do not specifically address how the body interacts with the medication. 6. Therapeutic dosage range (D) is related to dosing but doesn't cover all aspects of pharmacokinetics.
Question 4 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 5 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.
