A client arrives to the emergency department with chest pain after taking sildenafil. Based on the client's history, which medication should the nurse withhold?

Aspirin.

Nitroglycerin.

Morphine.

Heparin.

Answer and Explanation

The Correct Answer is B

Rationale

A. Aspirin is commonly used in the emergency setting for chest pain suspected to be due to acute coronary syndrome (ACS), which includes conditions like myocardial infarction (heart attack). It works by reducing blood clotting and can help alleviate symptoms in some cases. It is typically safe to administer aspirin

B. Sildenafil can interact with nitrates, such as nitroglycerin, and result in a significant drop in blood pressure. Therefore, the nurse should withhold nitroglycerin to prevent potential adverse effects.

C. Morphine is a potent opioid pain medication used in the emergency department for severe pain relief, including chest pain associated with suspected myocardial infarction. It can help reduce pain and anxiety in acute coronary syndromes. It has no significant interaction with sildenafil.

D. Heparin is an anticoagulant medication used to prevent blood clotting. It is often administered in the hospital setting for various indications, such as deep vein thrombosis, pulmonary embolism, or in some cases of acute coronary syndromes.

Correct Answer is ["18"]

Explanation

(Desired Dose * Volume of IV Bag) / (Concentration of Drug in IV Bag * Time) = Infusion Rate.

For the given prescription, the calculation would be: (900 units/hr * 500 mL) / (25,000 units) = 18 mL/hr.

Therefore, the nurse should program the infusion pump to deliver 18 mL/hr.

A. Ask the client's friend to sign the informed consent since the client is unresponsive. B. Notify the unit manager that an emergency court order is needed to allow surgery. C. Carry on with surgical preparation of the client without a signed informed consent. D. Continue to provide life support until a thorough search for a guardian is completed.

Correct Answer is C

Explanation

Rationale

A. The client's friend may not legally be authorized to provide consent unless they hold medical power of attorney or legal guardianship for the client. Without documentation of such authority, the friend cannot sign the informed consent.

B. In emergency situations where a patient lacks decision-making capacity and there is no available legal guardian or next of kin to provide consent, hospitals may seek a court order to proceed with necessary treatment. However, this could delay emergency treatment.

C. This is based on the legal and ethical understanding that saving the patient's life takes precedence when immediate action is required and consent cannot be obtained.

D. Providing life support ensures that the client's immediate medical needs are addressed while efforts are made to locate a legal guardian. However, unavailability of next of kin should not delay definitive intervention
