Nursing Elites

1. 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.

2. A client is receiving sulfisoxazole. Which of the following should be included in the list of instructions?

• A. Restrict fluid intake.
• B. Maintain a high fluid intake.
• C. If the urine turns dark brown, call the healthcare provider (HCP) immediately.
• D. Decrease the dosage when symptoms are improving to prevent an allergic response.

Correct answer: B

Rationale: When a client is taking sulfisoxazole, it is important to maintain a high fluid intake. Each dose of sulfisoxazole should be taken with a full glass of water, as the medication is more soluble in alkaline urine. Restricting fluid intake is not recommended as it can lead to inadequate hydration. Dark brown urine may be a side effect of some forms of sulfisoxazole but does not necessarily warrant immediate notification of the healthcare provider unless accompanied by other concerning symptoms. Decreasing the dosage when symptoms improve is not advised as it may lead to treatment failure or the development of resistance.

3. A client taking fexofenadine (Allegra) is scheduled for allergy skin testing and tells the nurse in the healthcare provider's office that a dose was taken this morning. The nurse determines that:

• A. The client should reschedule the appointment.
• B. A lower dose of allergen will need to be injected.
• C. A higher dose of allergen will need to be injected.
• D. The client should have the skin test read a day later than usual.

Correct answer: A

Rationale: Fexofenadine, an antihistamine, can cause false-negative readings in allergy skin testing and should be discontinued 3 days prior. Therefore, the client should reschedule the appointment to ensure accurate test results.

4. A client with severe acne is seen in the clinic, and the healthcare provider prescribes isotretinoin. The nurse reviews the client's medication record and would contact the healthcare provider if the client is taking which medication?

• A. Vitamin A
• B. Digoxin (Lanoxin)
• C. Furosemide (Lasix)
• D. Phenytoin (Dilantin)

Correct answer: A

Rationale: Isotretinoin is a metabolite of vitamin A, which can lead to toxicity when taken together. Therefore, it is crucial to avoid concurrent use of vitamin A supplements with isotretinoin. Contacting the healthcare provider to discuss discontinuing vitamin A supplements is important to prevent potential adverse effects. Choices B, C, and D are incorrect as they are not known to interact significantly with isotretinoin.

5. A histamine (H2)-receptor antagonist will be prescribed for a client. The nurse understands that which medications are H2-receptor antagonists? Select one that doesn't apply.

• A. Nizatidine (Axid)
• B. Ranitidine (Zantac)
• C. Famotidine (Pepcid)
• D. Ibuprofen (Motrin)

Correct answer: D

Rationale: H2-receptor antagonists like Nizatidine, Ranitidine, and Famotidine are used to suppress gastric acid secretion, relieve heartburn symptoms, and prevent complications of peptic ulcer disease. Ibuprofen, on the other hand, is a nonsteroidal anti-inflammatory drug (NSAID) commonly used for pain relief and inflammation, but it is not an H2-receptor antagonist. It is essential to differentiate between these medication classes to ensure appropriate treatment for gastrointestinal conditions.
