Which category is characterized as objective data?

The ages and relationship of all household members

Usual dietary patterns and intake

A list of herbal supplements regularly used

Lab values associated with the drugs the patient is taking

Answer and Explanation

The Correct Answer is D

A. The ages and relationships of household members are subjective data because they are reported by the patient and not directly measured or observed.

B. Usual dietary patterns and intake are also subjective data, as they rely on patient self-reporting rather than measurable, verifiable findings.

C. A list of herbal supplements regularly used is subjective because it depends on the patient’s recall and self-reporting rather than objective measurement.

D. Lab values are considered objective data because they are measurable, verifiable, and obtained through diagnostic testing rather than patient self-reporting. Objective data are based on observable and quantifiable factors, making them more reliable for clinical decision-making.

Correct Answer is ["A","C"]

Explanation

a) Teaching the patient how to cope with therapy is part of the nurse's responsibility to ensure the patient understands the treatment regimen, side effects, and how to manage any challenges, thus improving outcomes.

b) Providing therapy refers to administering medications, but nurses generally do not "provide therapy" in the broader sense (such as deciding what therapy a patient needs beyond the prescribed drug regimen).

c) Evaluating the effectiveness of therapy is the nurse's responsibility as part of the ongoing assessment. The nurse should monitor how well the drug is working and identify any adverse effects.

d) Altering the drug regimen is outside the nurse’s scope of practice. Nurses can suggest changes or communicate concerns, but altering drug regimens requires a healthcare provider’s approval.

e) Recommending over-the-counter medications for adverse effects is not within the nurse's scope unless advised by a healthcare provider. Nurses should guide patients based on provider orders and not independently suggest over-the-counter remedies.

A. Bioavailability B. Pinocytosis C. Tachyphylaxis D. Protein binding

Correct Answer is A

Explanation

a) Bioavailability refers to the proportion of the drug that reaches systemic circulation when administered by a particular route. The oral route typically has lower bioavailability than the intravenous route due to the first-pass metabolism in the liver. Therefore, when switching from an IV form to an oral form, the dose often needs to be higher to achieve the same therapeutic effect.

b) Pinocytosis is a form of endocytosis where cells absorb fluids and small molecules. While important in drug absorption, it is not the reason why oral doses are higher than IV doses.

c) Tachyphylaxis is a rapid tolerance to a drug after its administration, often requiring higher doses over time, but it does not directly explain the need for a higher oral dose.

d) Protein binding refers to how drugs bind to proteins in the blood, which can affect their distribution. However, this is not the main reason why oral doses are higher than IV doses.
