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: Increased respiratory rate is not a sign of adverse reaction to metoprolol, but rather a normal response to hypoxia or distress. Metoprolol is a betablocker that can lower the heart rate and blood pressure, but it does not affect the respiratory rate directly.
Choice B reason: Bronchodilation is not a sign of adverse reaction to metoprolol, but rather a desired effect of asthma medications such as betaagonists or anticholinergics. Metoprolol is a betablocker that can block the beta receptors in the lungs, which can cause bronchoconstriction or narrowing of the airways. This is why metoprolol is contraindicated or used with caution in clients with asthma.
Choice C reason: Decreased sputum production is not a sign of adverse reaction to metoprolol, but rather a result of effective asthma management. Metoprolol is a betablocker that does not have any direct effect on the mucus secretion or inflammation in the lungs.
Choice D reason: Wheezing is a sign of adverse reaction to metoprolol, as it indicates bronchoconstriction or narrowing of the airways. Metoprolol is a betablocker that can block the beta receptors in the lungs, which can reduce the bronchodilation effect of beta agonists or other asthma medications. This can worsen the asthma symptoms and cause wheezing, coughing, dyspnea, or chest tightness. The nurse should monitor the client for these signs and report them to the prescriber immediately.
Correct Answer is B
Explanation
Choice A reason: 3% sodium chloride is a hypertonic solution that can cause fluid shifts and dehydration. It is not a suitable replacement for TPN, which is also hypertonic but provides calories, electrolytes, vitamins, and minerals. Infusing 3% sodium chloride can lead to hypernatremia, increased intracranial pressure, and cellular damage.
Choice B reason: Dextrose 10% in water is a hypertonic solution that can provide some calories and prevent hypoglycemia. It is the best option among the choices to replace TPN temporarily, until the new container arrives. However, it does not provide adequate nutrition or electrolytes, so it should not be used for a long time.
Choice C reason: Lactated Ringer's is an isotonic solution that can maintain fluid balance and electrolytes. It is not a suitable replacement for TPN, which is hypertonic and provides more calories and nutrients. Infusing Lactated Ringer's can lead to fluid overload, hyponatremia, and metabolic alkalosis.
Choice D reason: 0.9% sodium chloride is an isotonic solution that can maintain fluid balance and sodium levels. It is not a suitable replacement for TPN, which is hypertonic and provides more calories and nutrients. Infusing 0.9% sodium chloride can lead to fluid overload, hyponatremia, and metabolic acidosis.
