When educating a patient about Lorazepam (Ativan), the nurse should advise against the concurrent use of which substance?
Vitamin C supplements
Caffeinated beverages
Alcohol
Dairy products
The Correct Answer is C
Choice A reason: Vitamin C supplements are not a concern for the concurrent use with Lorazepam, which is a medication that reduces anxiety and insomnia by enhancing the effects of a neurotransmitter called gammaaminobutyric acid (GABA) in the brain¹. Vitamin C is an essential nutrient that supports the immune system and the synthesis of collagen, a protein that forms the connective tissue in the body. Vitamin C does not interact with Lorazepam or affect its metabolism or clearance.
Choice B reason: Caffeinated beverages are not a concern for the concurrent use with Lorazepam, but they may reduce its effectiveness or cause unwanted effects. Caffeine is a stimulant that increases the activity of the central nervous system and counteracts the sedative and calming effects of Lorazepam. Caffeine may also cause side effects such as nervousness, insomnia, or palpitations, especially in high doses or in sensitive individuals. The nurse should advise the patient to limit or avoid caffeine intake while taking Lorazepam, and to monitor their response to the medication.
Choice C reason: Alcohol is a concern for the concurrent use with Lorazepam, as it can increase the risk of serious and potentially fatal side effects. Alcohol is a depressant that slows down the activity of the central nervous system and enhances the effects of Lorazepam. Alcohol can cause additive effects such as excessive sedation, respiratory depression, coma, or death when taken with Lorazepam. The nurse should advise the patient to avoid alcohol consumption while taking Lorazepam, and to seek immediate medical attention if they experience any signs of overdose or toxicity.
Choice D reason: Dairy products are not a concern for the concurrent use with Lorazepam, as they do not affect its absorption, distribution, metabolism, or excretion. Dairy products are a source of calcium, protein, and other nutrients that support the bone health and the muscle function. Dairy products do not interact with Lorazepam or alter its pharmacokinetics or pharmacodynamics.

Correct Answer is D
Explanation
Choice A reason: Allergy is an immune mediated reaction to a substance that causes symptoms such as rash, itching, swelling, or anaphylaxis. It is not related to the duration or effectiveness of the medication. The patient does not report any signs of allergy to the opioids.
Choice B reason: Addiction is a chronic and compulsive disorder that involves seeking and using a substance despite harmful consequences. It is characterized by loss of control, craving, and impaired functioning. The patient does not show any signs of addiction to the opioids, such as increasing the dose, obtaining the medication illegally, or neglecting other responsibilities.
Choice C reason: Withdrawal is a syndrome that occurs when a substance is abruptly discontinued or reduced after prolonged use. It causes physical and psychological symptoms such as anxiety, agitation, sweating, nausea, or tremors. The patient does not experience any signs of withdrawal from the opioids, as they are still taking the medication as prescribed.
Choice D reason: Tolerance is a phenomenon that occurs when a substance loses its effectiveness over time due to repeated exposure. It requires higher doses or more frequent administration to achieve the same effect. The patient reports a sign of tolerance to the opioids, as they feel that the medication does not work as well anymore. The nurse should assess the patient's pain level, monitor the opioid dose, and consult with the prescriber about possible adjustments or alternatives.
Correct Answer is ["B","C"]
Explanation
Choice A reason: This is incorrect. Polydipsia is excessive thirst, which is a symptom of hyperglycemia (high blood sugar), not hypoglycemia (low blood sugar). People with hyperglycemia lose fluid through frequent urination and become dehydrated, which makes them thirsty.
Choice B reason: This is correct. Shaking is a common sign of hypoglycemia. It occurs because the body releases adrenaline and other hormones to raise blood sugar levels. Adrenaline causes the muscles to tremble or shake.
Choice C reason: This is correct. Confusion is another common sign of hypoglycemia. It occurs because the brain does not get enough glucose, which is its main source of energy. Low blood sugar can impair cognitive functions, such as memory, attention, and judgment.
Choice D reason: This is incorrect. Tachycardia is a rapid heart rate, which can be a symptom of both hypoglycemia and hyperglycemia. However, it is not a specific or reliable indicator of low blood sugar, as it can also be caused by other factors, such as stress, anxiety, caffeine, or medication.
Choice E reason: This is incorrect. Polyuria is excessive urination, which is another symptom of hyperglycemia, not hypoglycemia. People with hyperglycemia have high levels of glucose in their blood, which draws water from the cells and increases urine output.
