Complete the following using the list of options.
Mr. Brown is a 75-year-old client in for a routine check-up. He has several prescribed medications. The nurse knows that taking numerous drugs is known as:
Drug tolerance.
Pharmacogenetic reaction.
Drug toxicity.
Polypharmacy.
The Correct Answer is D
Choice A rationale
Drug tolerance refers to a phenomenon where a patient's response to a specific drug decreases over time, requiring larger doses to achieve the same therapeutic effect. This often occurs due to physiological adaptations, such as altered receptor sensitivity or increased drug metabolism, and is distinct from simply taking multiple medications.
Choice B rationale
A pharmacogenetic reaction involves an individual's unique genetic makeup influencing their response to a drug, leading to altered drug metabolism, efficacy, or adverse effects. This is a specific type of drug response based on genetic variations and is not synonymous with the practice of taking numerous medications.
Choice C rationale
Drug toxicity refers to adverse effects that occur when the concentration of a drug in the body exceeds the therapeutic range, leading to harmful or undesirable physiological effects. While taking multiple drugs can increase the risk of toxicity, toxicity itself is a consequence, not the term for taking numerous drugs.
Choice D rationale
Polypharmacy is the medical term used to describe the practice of taking multiple medications concurrently, often more than is medically necessary or when the potential for adverse drug interactions and side effects outweighs the benefits. This is a common issue in older adults due to the presence of multiple chronic conditions requiring different pharmacological interventions.

Correct Answer is ["0.45"]
Explanation
Step 1 is to determine the volume to administer. 4500 units ÷ (10,000 units/1 mL) = 0.45 mL. The nurse will administer 0.45 mL.
Correct Answer is A
Explanation
Choice A rationale
A bruit is an abnormal vascular sound, typically a loud, whooshing, or blowing murmur, caused by turbulent blood flow through a narrowed or partially obstructed artery. It is best auscultated with the bell of the stethoscope, which is more effective at detecting low-pitched sounds due to its larger surface area and ability to transmit vibrations from a broader area of contact. The turbulence creates vibratory patterns indicative of compromised blood flow.
Choice B rationale
A high-pitched tinkling sound is not characteristic of a bruit and is more commonly associated with bowel sounds in cases of intestinal obstruction, indicating fluid and gas movement within the bowel. The diaphragm of the stethoscope is indeed used for high-pitched sounds, but this specific sound quality does not align with the pathophysiology of a vascular bruit.
Choice C rationale
A soft, trickling, pulsatile sound does not describe a bruit. While pulsatile, the "soft, trickling" quality suggests a very low-flow state or venous hum rather than the turbulent arterial flow responsible for a true bruit. The bell is appropriate for low-pitched sounds, but the character of the sound is inconsistent with a bruit.
Choice D rationale
A low gurgling sound is generally associated with gastrointestinal motility, such as normal bowel sounds, and is not indicative of a vascular bruit. While low-pitched sounds can be detected with the bell, the diaphragm is used for higher-pitched sounds, and the "gurgling" description is inappropriate for arterial turbulence.
