1. Mafenide acetate (Sulfamylon) is prescribed for a 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: The correct action is to inform the client that local discomfort and burning are normal reactions to Mafenide acetate. This medication is used to treat burns by reducing bacteria in avascular tissues. Discontinuing the medication or applying a thinner film than prescribed is not necessary or recommended in this situation.
2. Which of the following herbal therapies would be prescribed for its use as an antispasmodic? Select all that apply.
- A. Aloe
- B. Kava
- C. Ginger
- D. Chamomile
Correct answer: D
Rationale: Chamomile is known for its antispasmodic properties. It helps in relaxing muscles and reducing spasms. Aloe is a laxative, kava has anxiolytic and sedative effects, and ginger is commonly used to relieve nausea.
3. When monitoring a client for acute toxicity associated with bethanechol chloride (Urecholine), what sign should the nurse check for to indicate toxicity?
- A. Dry skin
- B. Dry mouth
- C. Bradycardia
- D. Signs of dehydration
Correct answer: C
Rationale: The correct answer is C: Bradycardia. Toxicity from bethanechol chloride (Urecholine) can lead to excessive muscarinic stimulation, resulting in manifestations like salivation, sweating, involuntary urination and defecation, bradycardia, and severe hypotension. When facing toxicity, treatment involves supportive measures and administering atropine sulfate subcutaneously or intravenously.
4. Which laboratory test should the nurse monitor to determine the effectiveness of heparin therapy for a client with deep vein thrombosis?
- A. Platelet count
- B. Prothrombin time (PT)
- C. Activated partial thromboplastin time (aPTT)
- D. Hemoglobin and hematocrit
Correct answer: C
Rationale: The activated partial thromboplastin time (aPTT) is the specific laboratory test used to monitor the effectiveness of heparin therapy in patients with deep vein thrombosis. It measures the time it takes for blood to clot and is crucial in assessing the therapeutic range of heparin. Platelet count, prothrombin time (PT), and hemoglobin and hematocrit levels are important parameters in assessing coagulation and blood status but do not directly indicate the effectiveness of heparin therapy.

- A. Diarrhea
- B. Excitability
- C. Drowsiness
- D. Excess salivation

Rationale: Cetirizine hydrochloride (Zyrtec) is known to commonly cause drowsiness or sedation as a side effect. Therefore, the nurse should monitor the client for signs of drowsiness when administering this medication. Choice A, Diarrhea, is not a common side effect of cetirizine. Choice B, Excitability, is not a typical side effect of this antihistamine; instead, it tends to cause drowsiness. Choice D, Excess salivation, is not associated with cetirizine use.
