Question 1 of 5
A 23-year-old man victim of a motor vehicle accident is brought to the emergency department. He is found to have a blood alcohol level of 850 mg/dL. Because of the way the body handles ethanol, the conventional 'half-life' to describe its metabolism does not apply. Which of the following drugs at therapeutic concentrations exhibits the same property?
Correct Answer: D
Rationale: Ethanol's zero-order metabolism matches phenytoin , saturating enzymes at therapeutic levels. Aspirin , ibuprofen , simvastatin , and valproic acid (E) follow first-order kinetics. Phenytoin's fixed-rate clearance mirrors ethanol's.
Question 2 of 5
The client takes calcium supplements. What is the best instruction by the nurse?
Correct Answer: B
Rationale: Calcium absorbs best with food-e.g., fat aids uptake, per pharmacokinetics-unlike empty stomach. Insomnia isn't typical-constipation is. Vitamin D matters-enhances absorption. Meal timing optimizes use, per guidance.
Question 3 of 5
Nurse Bryan knows that the age group that uses the most units of blood and blood products is:
Correct Answer: A
Rationale: Premature infants, especially those born very premature or with health complications, often require blood transfusions due to their underdeveloped organs and medical conditions. Their small size and medical fragility make them the age group that typically uses the most units of blood and blood products. This high demand for blood products is necessary to support their growth, development, and overall health. Conversely, while individuals in other age groups may also require blood transfusions, premature infants have specific and ongoing needs that often result in a greater overall use of blood and blood products in this age group.
Question 4 of 5
While preparing an infusion of mannitol (Osmitrol), the nurse notices small crystals in the IV tubing. What is the most appropriate action by the nurse?
Correct Answer: B
Rationale: The most appropriate action by the nurse when small crystals are observed in the IV tubing while preparing an infusion of mannitol (Osmitrol) is to discard the solution and obtain another bag of medication. Small crystals in the IV tubing can indicate that the medication may be contaminated or that it has precipitated out of solution, which can potentially lead to complications if infused into the patient. It is crucial to ensure that the medication is in proper form before administration to prevent any harm to the patient. Therefore, discarding the solution and obtaining a new bag of medication is the safest and most appropriate course of action in this situation.
Question 5 of 5
A patient who has been taking a benzodiazepine as a sleep aid for several months wishes to stop taking the medication. The nurse will suggest that the patient taper the dose gradually to avoid which effect?
Correct Answer: D
Rationale: Benzodiazepines, such as medications used for sleep aid, are known for their potential to cause physical dependence. If a patient abruptly stops taking benzodiazepines after using them regularly for an extended period, they are at risk of experiencing withdrawal symptoms. These withdrawal symptoms can be severe and may include rebound insomnia, anxiety, agitation, tremors, sweating, and even seizures in some cases. To prevent or minimize the likelihood of withdrawal symptoms, it is important for patients to gradually taper off the medication under the guidance of a healthcare provider. This gradual tapering helps the body adjust slowly to decreasing doses of the medication, reducing the risk of withdrawal effects.
