A nurse is caring for a client who received IV Verapamil to treat supraventricular tachycardia (SVT). The client's pulse rate is now 98/min and his blood pressure is 74/44 mg hg. The nurse should anticipate a prescription for which of the following IV medications?
- A. Calcium gluconate
- B. Sodium bicarbonate
- C. Potassium chloride
- D. Magnesium sulfate

Mafenide acetate (Sulfamylon) is prescribed for the client with a burn injury. When applying the medication, the client complains of local discomfort and burning. Which of the following is the most appropriate nursing action?
- A. Notifying the registered nurse
- B. Discontinuing the medication
- C. Informing the client that this is normal
- D. Applying a thinner film than prescribed to the burn site
Correct Answer: C
Rationale: Mafenide acetate is bacteriostatic for gram-negative and gram-positive organisms and is used to treat burns to reduce bacteria present in avascular tissues. The client should be informed that the medication will cause local discomfort and burning and that this is a normal reaction; therefore options 1, 2, and 4 are incorrect.
A client with Crohn's disease is scheduled to receive an infusion of infliximab (Remicade). The nurse assisting in caring for the client should take which action to monitor the effectiveness of treatment?
- A. Monitoring the leukocyte count for 2 days after the infusion
- B. Checking the frequency and consistency of bowel movements
- C. Checking serum liver enzyme levels before and after the infusion
- D. Carrying out a Hematest on gastric fluids after the infusion is completed
Correct Answer: B
Rationale: The principal manifestations of Crohn's disease are diarrhea and abdominal pain. Infliximab (Remicade) is an immunomodulator that reduces the degree of inflammation in the colon, thereby reducing the diarrhea. Options 1, 3, and 4 are unrelated to this medication.
What concept is considered when generic drugs are substituted for brand name drugs?
- A. Bioavailability
- B. Critical concentration
- C. Distribution
- D. Half-life
Correct Answer: A
Rationale: Bioavailability is the portion of a dose of a drug that reaches the systemic circulation and is available to act on body cells. Binders used in a generic drug may not be the same as those used in the brand name drug. Therefore, the way the body breaks down and uses the drug may differ, which may eliminate a generic drug substitution. Critical concentration is the amount of a drug that is needed to cause a therapeutic effect and should not differ between generic and brand name medications. Distribution is the phase of pharmacokinetics, which involves the movement of a drug to the body's tissues and is the same in generic and brand name drugs. A drug's half-life is the time it takes for the amount of drug to decrease to half the peak level, which should not change when substituting a generic medication.
