A nurse is caring for a client who is receiving parenteral nutrition and identifies that the client has hyperkalemia. Which of the following actions should the nurse take?

A. To assess compatibility of the verapamil with newly ordered medications: Verapamil is a calcium channel blocker used to treat hypertension, angina, and arrhythmias. It has potential interactions with many other medications due to its effects on cardiac conduction and blood
pressure. Therefore, consulting the pharmacist is important to assess compatibility and potential drug interactions when new medications are prescribed.
B. To request a change in the dosage of the verapamil: Changing the dosage of verapamil may require a healthcare provider's order rather than consultation with a pharmacist.
C. To verify the frequency of administration of the verapamil: The frequency of administration of verapamil is typically determined by the healthcare provider and documented in the prescription. The pharmacist's role may involve dispensing the medication as prescribed but not verifying the frequency unless there are discrepancies.
D. To report the client's refusal to take the verapamil: Reporting the client's refusal to take the medication should be communicated to the healthcare provider for further assessment and
intervention. The pharmacist's role is primarily related to medication dispensing and ensuring appropriate use rather than addressing client refusals.

A. Dobutamine: Dobutamine is a sympathomimetic medication used to increase cardiac output in conditions such as heart failure or cardiogenic shock. It is not indicated for the management of severe hypertension.

B. Epinephrine: Epinephrine is a sympathomimetic medication used for the management of severe allergic reactions (anaphylaxis), cardiac arrest, and severe asthma exacerbations. It is not indicated for the management of severe hypertension.
C. Dexamethasone: Dexamethasone is a corticosteroid medication used for a variety of

conditions, including inflammation, allergic reactions, and certain cancers. It is not indicated for the management of severe hypertension.
D. Nitroprusside: Nitroprusside is a potent vasodilator used for the rapid reduction of blood pressure in hypertensive emergencies, such as hypertensive crises or malignant hypertension. It acts quickly to dilate both arterial and venous vessels, leading to a rapid decrease in blood pressure. Therefore, it is the appropriate choice for this client with severe hypertension and a severe headache.
