1. Prednisone is prescribed for a client with diabetes mellitus who is taking Humulin neutral protamine Hagedorn (NPH) insulin daily. Which of the following prescription changes does the nurse anticipate during therapy with prednisone?
- A. An additional dose of prednisone daily
- B. A decreased amount of daily Humulin NPH insulin
- C. An increased amount of daily Humulin NPH insulin
- D. The addition of an oral hypoglycemic medication daily
Correct answer: C
Rationale: When prednisone is prescribed for a client with diabetes mellitus who is taking Humulin NPH insulin daily, the nurse should anticipate an increased amount of daily Humulin NPH insulin. Prednisone, a glucocorticoid, can elevate blood glucose levels, requiring an increase in insulin dosage to maintain optimal blood sugar control.
2. Which drink choice on a hot day indicates that a teenager with sickle cell anemia understands dietary considerations related to the disease?
- A. Milkshake
- B. Iced tea
- C. Diet cola
- D. Lemonade
Correct answer: D
Rationale: Lemonade is the correct choice for a teenager with sickle cell anemia as it provides hydration without caffeine, which is important for individuals with this condition. Caffeine can lead to dehydration, vasoconstriction, and potentially worsen symptoms in sickle cell anemia patients. Milkshake (choice A) may contain dairy, which can be high in fat and may not be the best choice for someone with sickle cell anemia. Iced tea (choice B) and diet cola (choice C) both contain caffeine, which should be avoided by individuals with sickle cell anemia due to its dehydrating effects.
3. The client is NPO and is receiving total parenteral nutrition (TPN) via a subclavian line. Which precautions should the nurse implement? Select one that does not apply.
- A. Place the solution on an IV pump at the prescribed rate.
- B. Monitor blood glucose every twelve (12) hours.
- C. Weigh the client weekly, first thing in the morning.
- D. Change the IV tubing every three (3) days.
Correct answer: D
Rationale: Precautions for clients receiving TPN include placing the solution on an IV pump to control the rate, monitoring blood glucose levels to detect hyperglycemia, and monitoring intake and output to assess fluid balance. Changing the IV tubing every three days is not a standard precaution for clients receiving TPN via a subclavian line.
4. The nurse is planning care for a client who is receiving phenytoin (Dilantin) for seizure control. Which intervention is most important to include in this client’s plan of care?
- A. Monitor serum calcium levels
- B. Obtain a baseline electrocardiogram
- C. Implement seizure precautions
- D. Encourage a low-protein diet
Correct answer: C
Rationale: The correct answer is to implement seizure precautions. Phenytoin is an antiepileptic medication used for seizure control. Seizure precautions are crucial for clients taking this medication to ensure their safety during a seizure episode. Monitoring serum calcium levels (Choice A) is not directly related to phenytoin therapy. Obtaining a baseline electrocardiogram (Choice B) is important for some medications but not the priority for a client on phenytoin. Encouraging a low-protein diet (Choice D) is not specifically indicated for clients on phenytoin and is not the most important intervention.
5. A client has a nursing diagnosis of Altered sleep patterns related to nocturia. Which client instruction is important for the nurse to provide?
- A. Decrease intake of fluids after the evening meal.
- B. Drink a glass of cranberry juice every day.
- C. Drink a glass of warm decaffeinated beverage at bedtime.
- D. Consult the healthcare provider about a sleeping pill.
Correct answer: A
Rationale: The correct instruction for the nurse to provide is to advise the client to decrease intake of fluids after the evening meal. By reducing fluid intake before bedtime, the client can minimize the need to void during the night, which can help improve sleep patterns affected by nocturia. Choices B, C, and D are incorrect. Drinking cranberry juice or warm decaffeinated beverage at bedtime may increase fluid intake, exacerbating the nocturia issue. Consulting the healthcare provider about a sleeping pill should not be the first intervention, as it is important to try non-pharmacological approaches first.
