1. The burn client is receiving treatments of topical mafenide acetate (Sulfamylon) to the site of injury. The nurse monitors the client, knowing that which of the following indicates that a systemic effect has occurred?

A. Hyperventilation
B. Elevated blood pressure
C. Local pain at the burn site
D. Local rash at the burn site

Correct answer: A

Rationale: Hyperventilation is an indication of a systemic effect of mafenide acetate (Sulfamylon) due to its potential to cause acidosis by suppressing renal excretion of acid. If hyperventilation occurs, the medication should be discontinued to prevent further complications.

2. In a client with chronic renal failure receiving epoetin alfa (Epogen, Procrit), which laboratory result would indicate a therapeutic effect of the medication?

A. Hematocrit of 32%
B. Platelet count of 400,000 cells/mmÂ³
C. White blood cell count of 6000 cells/mmÂ³
D. Blood urea nitrogen (BUN) level of 15 mg/dL

Correct answer: A

Rationale: A hematocrit of 32% indicates a therapeutic effect of epoetin alfa in a client with chronic renal failure. Epoetin alfa is used to treat anemia in these patients by stimulating red blood cell production, leading to an increase in the hematocrit level. Monitoring the hematocrit is essential to assess the response to epoetin alfa therapy.

3. A client with diabetes mellitus visits a health care clinic. The client's diabetes mellitus was previously well controlled with daily glyburide (DiaBeta). However, the fasting blood glucose level has recently been in the range of 180 to 200 mg/dL. Which medication, if added to the client's regimen, may have contributed to the hyperglycemia?

A. Prednisone
B. Phenelzine (Nardil)
C. Atenolol (Tenormin)
D. Allopurinol (Zyloprim)

Correct answer: A

Rationale: Prednisone is known to reduce the effectiveness of oral hypoglycemic medications like glyburide and insulin, which can result in hyperglycemia. Therefore, the addition of prednisone to the client's regimen could have contributed to the elevated fasting blood glucose levels observed.

4. A client is on nicotinic acid (niacin) for hyperlipidemia and the nurse provides instructions to the client about the medication. Which statement by the client would indicate an understanding of the instructions?

A. It is not necessary to avoid the use of alcohol.
B. The medication should be taken with meals to decrease flushing.
C. Clay-colored stools are a common side effect and should not be of concern.
D. Ibuprofen (Motrin) taken 30 minutes before the nicotinic acid should decrease the flushing.

Correct answer: D

Rationale: Aspirin or a nonsteroidal anti-inflammatory drug can be taken 30 minutes before taking the medication to decrease flushing. Alcohol consumption needs to be avoided because it will enhance this side effect. The medication should be taken with meals, this will decrease gastrointestinal upset. Taking the medication with meals has no effect on the flushing. Clay-colored stools are a sign of hepatic dysfunction and should be immediately reported to the health care provider (HCP).

5. The client who chronically uses nonsteroidal anti-inflammatory drugs (NSAIDs) has been taking misoprostol (Cytotec). The nurse determines that the medication is having the intended therapeutic effect if which of the following is noted?

A. Resolved diarrhea
B. Relief of epigastric pain
C. Decreased platelet count
D. Decreased white blood cell count

Correct answer: B

Rationale: Misoprostol is a gastric protectant administered to clients using NSAIDs to prevent gastric mucosal injury. Relief of epigastric pain signifies the medication's therapeutic effect as it indicates a reduction in gastrointestinal symptoms associated with NSAID use.
