A nurse working in radiology administers iodine to a patient who is having a computed tomography (CT) scan.
The nurse working on the oncology unit administers chemotherapy to a patient who has cancer.
At the public health department, a nurse administers a measles mumps rubella vaccine to a 14-month-old child as a routine immunization.
Which branch of pharmacology best describes the actions of the three nurses?

Choice A rationale

Monitoring the weekly pulse is not sufficient for managing ventricular arrhythmias at home. Continuous or daily monitoring of vital parameters is more effective.

Choice B rationale

Monitoring daily fluid intake is essential for overall health but not directly related to the management of ventricular arrhythmias with propranolol (Inderal).

Choice C rationale

Daily blood pressure monitoring is crucial for patients on propranolol, as this medication can significantly lower blood pressure, and tracking it helps prevent hypotension.

Choice D rationale

Weekly weight monitoring is important for patients with heart conditions, but daily monitoring of blood pressure is more directly related to the management of ventricular arrhythmias with propranolol.

Choice A rationale

Using an “ouch” scale, such as the Wong-Baker FACES Pain Rating Scale, is appropriate for young children. It allows them to express their pain intensity in a way that is understandable and relatable to their age group.

Choice B rationale

Encouraging a six-year-old to request pain medication may not be effective, as they might not understand when they need it or might be reluctant to ask.

Choice C rationale

Waiting to administer pain medication until the child begins to cry can delay pain relief, leading to unnecessary discomfort and anxiety.

Choice D rationale

Asking a young child to rate their pain on a scale of 1 to 10 might be confusing and less effective than using a more child-friendly method like the “ouch” scale.
