1. Carbamazepine (Tegretol) is prescribed for a client with a diagnosis of psychomotor seizures. The nurse reviews the client's health history, knowing that this medication is contraindicated if which of the following disorders is present?
- A. Headaches
- B. Liver disease
- C. Hypothyroidism
- D. Diabetes mellitus
Correct answer: B
Rationale: Carbamazepine (Tegretol) is contraindicated in liver disease due to its potential to cause hepatic toxicity. Regular monitoring of liver function tests is necessary when using this medication to detect any signs of liver damage.
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 is taking Humulin NPH insulin daily every morning. The nurse reinforces instructions for the client and tells the client that the most likely time for a hypoglycemic reaction to occur is:
- A. 2 to 4 hours after administration
- B. 4 to 12 hours after administration
- C. 16 to 18 hours after administration
- D. 18 to 24 hours after administration
Correct answer: B
Rationale: Humulin NPH is an intermediate-acting insulin with a peak action time of 4 to 12 hours after administration. During this period, the risk of hypoglycemic reactions is highest. It is important for the client to be aware of this timing to prevent, recognize, and manage hypoglycemia effectively.
4. A client who is taking hydrochlorothiazide (HydroDIURIL, HCTZ) has been started on triamterene (Dyrenium) as well. The client asks the nurse why both medications are required. The nurse formulates a response, based on the understanding that:
- A. Both are weak potassium-losing diuretics.
- B. The combination of these medications prevents renal toxicity.
- C. Hydrochlorothiazide is less expensive, so using a combination of diuretics is cost-effective.
- D. Triamterene is a potassium-sparing diuretic, whereas hydrochlorothiazide is a potassium-losing diuretic.
Correct answer: D
Rationale: The combination of triamterene and hydrochlorothiazide is used because triamterene is a potassium-sparing diuretic, which helps retain potassium, while hydrochlorothiazide is a potassium-losing diuretic, which promotes potassium excretion. This combination helps balance potassium levels in the body, preventing imbalances that can occur when using potassium-losing diuretics alone.
5. A client who had a kidney transplant is receiving therapy with cyclosporine (Sandimmune). Which statement by the client indicates a need for further instruction?
- A. I need to obtain a yearly influenza vaccine.
- B. I need to have dental checkups every 3 months.
- C. I need to self-monitor my blood pressure at home.
- D. I need to call the health care provider (HCP) if my urine volume decreases or my urine becomes cloudy.
Correct answer: A
Rationale: The correct answer is A. Cyclosporine is an immunosuppressant that can reduce the effectiveness of vaccines. Clients should avoid vaccinations without consulting their health care provider to prevent potential complications or reduced efficacy of the vaccines.
