1. A client is being monitored while receiving bethanechol chloride (Urecholine) for urinary retention. Which of the following indicates a therapeutic effect of this medication?
- A. Increased heart rate
- B. Increased peristalsis
- C. Passage of flatus
- D. Urinary output of 50 mL per hour
Correct answer: D
Rationale: Bethanechol chloride (Urecholine) is administered to stimulate the bladder and treat urinary retention. The therapeutic effect is indicated by an increased urinary output, as it demonstrates the medication's ability to prompt the bladder to empty. Increased heart rate and passage of flatus are unrelated to the therapeutic effects of bethanechol. Although bethanechol can increase peristalsis, the primary therapeutic goal is to address urinary retention.
2. The client with breast cancer is receiving cyclophosphamide (Neosar). The nurse is reinforcing medication instructions and advises the client to:
- A. Take the medication with food.
- B. Increase fluid intake to 2000 to 3000 mL daily.
- C. Decrease sodium intake while taking the medication.
- D. Increase potassium intake while taking the medication.
Correct answer: B
Rationale: The correct answer is to increase fluid intake to 2000 to 3000 mL daily. Cyclophosphamide can cause hemorrhagic cystitis as a toxic effect. By increasing fluid intake, the client can help prevent this complication by promoting frequent urination, which reduces the concentration of the drug and its metabolites in the bladder. This dilution effect can help reduce the risk of bladder toxicity.
3. The home health care nurse is visiting a client who was recently diagnosed with type 2 diabetes mellitus. The client is prescribed repaglinide (Prandin) and metformin (Glucophage) and asks the nurse to explain these medications. The nurse should reinforce which instructions to the client? Select one that doesn't apply.
- A. Diarrhea can occur secondary to the metformin.
- B. The repaglinide is not taken if a meal is skipped.
- C. The repaglinide is taken 30 minutes before eating.
- D. Nausea and vomiting
Correct answer: D
Rationale: Repaglinide is a rapid-acting oral hypoglycemic that should be taken before meals and withheld if the client does not eat. Hypoglycemia is a side effect of repaglinide, so carrying a simple sugar is essential. Metformin decreases hepatic glucose production and can cause diarrhea. Muscle pain may occur as an adverse effect and should be reported to the HCP.
4. 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.
5. Colcrys (colchicine) is prescribed for a client with a diagnosis of gout. The nurse reviews the client's medical history in the health record, knowing that the medication would be contraindicated in which disorder?
- A. Myxedema
- B. Renal failure
- C. Hypothyroidism
- D. Diabetes mellitus
Correct answer: B
Rationale: Colchicine is contraindicated in clients with severe gastrointestinal, renal, hepatic, or cardiac disorders, or blood dyscrasias. Renal failure is a condition where the kidneys fail to function adequately, leading to the accumulation of toxins in the body. Since colchicine is contraindicated in clients with renal disorders, including renal failure, it could exacerbate the condition and worsen the client's health. Myxedema, hypothyroidism, and diabetes mellitus are not contraindications for colchicine use. While these conditions may require caution or monitoring when administering colchicine, they are not absolute contraindications like renal failure.
