Question 1 of 5
Angiotension II receptor agents medications usually end in?
Correct Answer: A
Rationale: Angiotensin II receptor agents medications usually end in -sartan. Examples of such medications include losartan, valsartan, and telmisartan. These drugs work by blocking the action of angiotensin II at its receptor sites, resulting in vasodilation and decreased aldosterone secretion. This class of medications is commonly used to treat conditions like hypertension, heart failure, and diabetic nephropathy.

Question 3 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.
Question 4 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 5 of 5
Jonas comes into the local blood donation center. He says he is here to donate platelets only today. The nurse knows this process is called:
Correct Answer: C
Rationale: Apheresis is the process of selectively collecting specific blood components, such as platelets, while returning the remaining components to the donor. This method allows for the efficient collection of platelets without depleting the donor's red blood cells or plasma. Directed donation refers to donating blood for a specific recipient, autologous donation involves donating one's own blood for future use, and allogeneic donation is the standard donation for the general blood supply. Therefore, apheresis is the correct term for platelet-only donation.
