A nurse is caring for a patient who is receiving heparin by continuous IV infusion.
Which of the following medications should the nurse plan to administer in the event of an overdose?

Choice A rationale

Propranolol is sometimes used to prevent migraines, so a history of migraines would not typically be a contraindication.

Choice B rationale

Hypothyroidism is not typically a contraindication for propranolol. However, propranolol can affect the metabolism of thyroid hormones and may mask signs of hyperthyroidism.

Choice C rationale

Propranolol is often used to treat hypertension, so a history of hypertension would not typically be a contraindication.

Choice D rationale

Propranolol is a non-selective beta-blocker, which means it blocks beta receptors in both the heart and the lungs. This can potentially cause bronchoconstriction and exacerbate asthma symptoms, so it should be used with caution in patients with a history of bronchial asthma.

Choice A rationale

Nausea and vomiting are common symptoms associated with migraines. Asking about these symptoms can help in assessing the severity of the migraine and planning appropriate interventions.

Choice B rationale

Sensitivity to light, also known as photophobia, is a common symptom of migraines. However, the presence of this symptom alone may not provide a comprehensive understanding of the patient’s condition.

Choice C rationale

While confusion or clouded thinking can occur with migraines, they are not as common as other symptoms such as nausea, vomiting, and sensitivity to light.

Choice D rationale

Feeling weak before the headache starts or currently feeling weak can be associated with migraines, but they are not the most common symptoms.
