A client receives a prescription for penicillin 1.2 million units IM. The available vial is labeled, "600,000 units/2 mL." How many mL should the nurse administer? (Enter numeric value only.)

A. Request a prescription to change the route of administration and use the available heparin:
Low molecular weight heparin (LMWH) and unfractionated heparin (UFH) are not interchangeable. LMWH is usually administered subcutaneously, whereas UFH is administered intravenously for acute situations. Changing the route of administration without a new prescription would not be appropriate.

B. Advise the pharmacy of the need to deliver a vial of heparin to the nursing unit immediately:
Since the prescription is for intravenous heparin and the available syringes are of LMWH (which is not suitable for IV use), it is essential to contact the pharmacy to provide the correct formulation. Immediate action ensures that the client receives the correct medication promptly.

C. Calculate and administer the equivalent dose of the available low molecular weight heparin:
Calculating and administering LMWH instead of UFH is inappropriate because they are different types of heparin with different indications, dosing regimens, and routes of administration. Using LMWH for an IV prescription could result in ineffective treatment or complications.

D. Dilute the available heparin in 250 mL of normal saline solution prior to IV administration:
LMWH should not be diluted or used in place of UFH for IV administration. This action is incorrect because the available medication is not suitable for the prescribed route and dose. The proper medication needs to be obtained from the pharmacy.

A. Clients using the discus may experience decreased blood pressure:
Fluticasone propionate and salmeterol are a combination of a corticosteroid and a long-acting beta-agonist. While they help control asthma, they are not typically associated with decreased blood pressure. Instead, potential side effects might include increased heart rate or hypertension.

B. Explain that the client should not use the discus more than twice daily:
Fluticasone propionate and salmeterol combination inhalers are usually prescribed for twice-daily use to maintain control of asthma symptoms. Using the inhaler more frequently than prescribed could lead to increased side effects or diminished effectiveness.

C. When using the discus, have the client breathe out rapidly into the mouthpiece:
The correct technique for using a dry powder inhaler involves inhaling deeply and forcefully to ensure the medication reaches the lungs. Breathing out rapidly into the mouthpiece is incorrect and will not deliver the medication effectively.

D. Offer the discus to the client for use during an acute asthma attack:
The discus is used for long-term control and prevention of asthma symptoms, not for immediate relief during an acute asthma attack. A rescue inhaler, typically containing a short-acting beta-agonist like albuterol, is used for acute symptoms.
