Question

Read the following scientific paper from J.K Aronson titled:

Medication errors: what they are, how they happen, and how to avoid them 

QJM: An International Journal of Medicine, Volume 102, Issue 8, August 2009, Pages 513– 521, https://doi.org/10.1093/qjmed/hcp052

Focus on the following sections:

  • Abstract
  • One particular medication error
  • Frequency and outcomes of medication errors
  • Conclusion: a prescription for better prescribing

Once you have done the reading:

Prepare a 150-200 words reflection piece on the importance of Topic 1 measurements for future health care professionals as you.

Base your reflection on the resources provided.

  • Drug Dosage and Body mass
  • Medication errors: what they are, how they happen, and how to avoid them)
  • You are most welcome to do quick research on measurement errors in your desired field of practice too (Pharmacy, Paramedic, Nutrition, Health Science, Exercise Science, Physiotherapy etc).

To help you out here are some questions to answer in your reflection:

  • What have you learned from the readings and calculations provided in Section 1 that you did not know before?
  • In your opinion, what is the importance of accurate measurements for future health care professionals like you? Explain your thoughts on this.
  • Focus on a particular medication error. Discuss how it could occur. What could be the consequences for the patient, health care professional and institution (e.g., hospital, pharmacy etc)?

Drug Dosage and Body Mass
In many cases, drug dosages are prescribed on the ba-
sis of body mass. For example, the recommended dos-
age of a drug may be 3 mg of drug for each kilogram of
body weight. In this case, a 50 kg (110 lb) woman would
receive 150 mg and an 82 kg (180 lb) man would get
246 mg. This adjustment is especially important
for children, because a dose suitable for an adult will
generally be to0 much for a child, who has much less
body mass. For this reason, manufacturers package and
sell smaller doses of certain drugs, such as aspirin, for

Drug dosage may also vary with age. Occasionally,
when an elderly patient has an impaired kidney or liver
function, the clearance of a drug from the body is de-
layed, and the drug may stay in the body longer than
is normal. This persistence can cause dizziness, vertigo,
and migraine-like headaches, resulting in falls and bro-
ken bones. Such delayed clearance must be monitored
and the drug dosage adjusted accordingly.
