A nurse is reviewing a client's prescribed medications. Which of the following situations represents a contraindication to medication administration?
An antibiotic medication that has a side effect of nausea when taken without food.
Administering medications to a client under 4 months of age.
A antihypertensive medication given for high-blood pressure that causes orthostatic hypotension.
A medication with a Blackbox warning that the drug causes tendonitis and the patient has a history of tendonitis.
The Correct Answer is D
A. An antibiotic medication that has a side effect of nausea when taken without food:
Nausea is a common side effect of many medications, including antibiotics, when taken on an empty stomach. While this side effect may cause discomfort, it is generally not a contraindication to medication administration. Patients can often manage this side effect by taking the medication with food or as advised by their healthcare provider.
B. Administering medications to a client under 4 months of age:
While administering medications to very young children requires special considerations and dosing adjustments, it is not inherently a contraindication. The key is to ensure that the medications are appropriate for the age and weight of the infant, and are prescribed and dosed correctly.
C. An antihypertensive medication given for high-blood pressure that causes orthostatic hypotension:
Orthostatic hypotension is a known side effect of some antihypertensive medications. While this side effect needs to be managed carefully, it does not represent a contraindication to the medication. Adjusting the dose or changing medications may be required to manage this side effect.
D. A medication with a Blackbox warning that the drug causes tendonitis and the patient has a history of tendonitis:
A Black Box warning is the strictest warning put in the labelling of a prescription drug by the FDA. It indicates that the drug has significant risk of serious or life-threatening adverse effects. If a medication with a Black Box warning indicates a risk of tendonitis and the patient has a history of tendonitis, this represents a contraindication, as the drug could exacerbate or trigger the condition, posing a serious risk to the patient.
