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.

Answer and Explanation

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.

Correct Answer is ["13.3"]

Explanation

Let's calculate the dosage step-by-step:

1. Determine the total daily dosage:
20 mg/dose x 4 doses/day = 80 mg/day

2. Calculate the volume needed for one dose:
20 mg / 1.5 mg/mL = 13.33 mL

3. Round to the nearest tenth:
13.33 L ≈ 13.3 mL

A. Parenteral medications are avoided due to fragility of veins. B. Older adults are at risk for drug toxicity due to accumulation in the body. C. The elderly population is susceptible to polypharmacy D. Medication metabolism tends to be faster in older adults. E. Older adults have delayed absorption. F. Older adults may require larger doses of medications.

Correct Answer is ["B","C","E"]

Explanation

A) Parenteral medications are avoided due to fragility of veins: While it is true that older adults may have fragile veins, this does not mean that parenteral medications are universally avoided. Parenteral medications are still used based on clinical needs, though careful consideration is given to the condition of the veins.

B) Older adults are at risk for drug toxicity due to accumulation in the body: This is correct. As people age, their liver and kidney functions often decline, leading to decreased metabolism and excretion of drugs. This can result in drug accumulation and an increased risk of toxicity.

C) The elderly population is susceptible to polypharmacy: This is correct. Older adults often take multiple medications for various chronic conditions, increasing the risk of drug interactions, side effects, and complications. Polypharmacy is a common issue in this population.

D) Medication metabolism tends to be faster in older adults: This is incorrect. Medication metabolism generally slows down in older adults due to decreased liver function. Slower metabolism can lead to drug accumulation and increased risk of adverse effects.

E) Older adults have delayed absorption: This is correct. Although the rate of absorption may not be significantly affected, the overall absorption can be altered due to changes in gastrointestinal function and blood flow in older adults.
