Question 1

All of the following statements about insulin are true, EXCEPT:

Accepted Answer

Insulin can also be given through other routes such as intravenous and intramuscular.

Question 2

In which class of the Vaughn-Williams classification system of antidysrhythmic medications does quinidine belong?

Accepted Answer

Quinidine belongs to class IA of the Vaughan-Williams classification system of antidysrhythmic medications, which block sodium channels and prolong the action potential duration.

Question 3

Glucagon will affect blood glucose levels by:

Accepted Answer

Glucagon works by inducing glycogenolysis, which is the breakdown of glycogen into glucose, and by stimulating gluconeogenesis, which is the production of glucose from non-carbohydrate sources such as amino acids and fatty acids. This results in an increase in blood glucose levels. Glucagon does not induce the storage of glucose, enhance absorption of glucose from the gastrointestinal tract, or enable the rapid absorption of glucose into cells.

Question 4

The FDA's numerical classification of a newly approved drug as "3" denotes it as a new:

Accepted Answer

The numerical classification "3" denotes a new formulation or dosage form not previously marketed. The other options do not match the definition of numerical classification "3."

Question 5

Which of the following medications would most likely be considered for emergent treatment in the prehospital management of hypertensive crisis?

Accepted Answer

Labetalol is a medication that can rapidly decrease blood pressure and is commonly used in prehospital management of hypertensive crisis. Nitroglycerin paste and enalaprilat have minimal impact on blood pressure in this context, and nifedipine has a risk of causing reflex tachycardia and hypotension.

Question 6

Methylphenidate (Ritalin), a drug used to treat attention deficit hyperactivity disorder (ADHD), achieves its therapeutic action by ________ the CNS, thereby causing ________ and allowing for greater concentration and focus.

Accepted Answer

Methylphenidate (Ritalin) works by stimulating the central nervous system (CNS), which leads to heightened awareness and arousal. This increased level of alertness helps individuals with ADHD concentrate and focus better.

Question 7

All of the following statements about hormone replacement therapy (HRT) with estrogen are true EXCEPT that HRT:

Accepted Answer

HRT with estrogen has been found to have no significant effect on delaying the onset of senile dementia in many patients. In fact, it may even increase the risk of developing dementia in some cases. The other statements are true about HRT with estrogen.

Question 8

A diuretic that affects reabsorption early in the nephron filtration process will:

Accepted Answer

A diuretic that affects reabsorption early in the nephron filtration process will have a greater impact on water and sodium removal because this is where the majority of sodium and water reabsorption occurs. Therefore, inhibiting this process will result in increased excretion of both water and sodium.

Question 9

All of the following result from administration of insulin, EXCEPT:

Accepted Answer

Insulin promotes glucose uptake by cells, leading to conversion of glucose to glycogen and increased cellular transport of glucose, potassium, and amino acids. It also stimulates protein, carbohydrate, lipid, and nucleic acid synthesis. However, insulin inhibits gluconeogenesis and glycogenolysis, so those processes do not result from its administration.

Question 10

In which class of the Vaughn-Williams classification system of antidysrhythmic medications does amiodarone belong?

Accepted Answer

Amiodarone belongs to Class III of the Vaughn-Williams classification system of antidysrhythmic medications. This class of medications prolongs the cardiac action potential duration and refractory period, which helps to stabilize cardiac rhythm.

Question 11

A larger-than-expected dose of adenosine may be necessary in patients regularly taking:

Accepted Answer

Aminophylline is a bronchodilator and may reduce the effectiveness of adenosine. Therefore, a larger dose of adenosine may be necessary in patients regularly taking aminophylline.

Question 12

The FDA's classification of a drug's treatment or therapeutic potential as "P" means that the drug:

Accepted Answer

According to the FDA, a drug's classification as "P" means that it offers an important therapeutic gain. This means that the drug provides significant benefits to patients in terms of safety and efficacy compared to existing treatments. This classification helps healthcare providers and patients understand the potential benefits of a new drug and make informed treatment decisions.

Question 13

According to Starling's Law, the administration of nitroglycerin will result in ________ preload, ________ stroke volume, and ________ myocardial oxygen demand.

Accepted Answer

Nitroglycerin decreases preload by dilating veins, which in turn can decrease stroke volume due to less end-diastolic volume. The overall effect also decreases myocardial oxygen demand by reducing the work the heart has to do.

Question 14

The use of tobacco, because of its nicotine content, may cause subtle symptoms due to stimulation of the:

Accepted Answer

The answer of The use of tobacco, because of its...

Question 15

A lesion in the posterior pituitary gland resulting in hypersecretion of ADH may result in:

Accepted Answer

The answer of A lesion in the posterior pituitary gland...

Question 16

Tachyphylaxis can be managed by:

Accepted Answer

The answer of Tachyphylaxis can be managed by:
...

Question 17

Which of the following statements about hemostatic agents, such as adenosine diphosphate (ADP) and thromboxane A2 (TXA2), is TRUE?

Accepted Answer

Hemostatic agents like ADP and TXA2 play a role in platelet activation and aggregation, which occurs early in the clotting process.

Question 18

All of the following statements about nonsteroidal anti-inflammatory drugs (NSAIDs) are true EXCEPT that NSAIDs:

Accepted Answer

Acetaminophen is not classified as an NSAID.

Question 19

Which of the following medications has the shortest half-life?

Accepted Answer

Adenosine has a half-life of only a few seconds, making it the medication with the shortest half-life among the options given. Verapamil has a half-life of around 7-9 hours, epinephrine has a half-life of around 2-3 minutes, and digitalis has a half-life of around 1.5 days.

Question 20

Which of the following is the generic name of a drug?

Accepted Answer

Diazepam is the only option given that is a generic drug name. Excedrin, Tylenol, and Motrin are all brand names.
