Nursing Elites

1. A client has a prescription for Phenytoin. Which of the following instructions should the nurse include?

• A. Take this medication at bedtime.
• B. Increase your intake of calcium-rich foods.
• C. Brush and floss your teeth regularly.
• D. Avoid eating foods high in potassium.

Correct answer: C

Rationale: The correct answer is C: 'Brush and floss your teeth regularly.' Phenytoin can cause gingival hyperplasia, a condition that leads to overgrowth of gum tissue. Good oral hygiene practices such as regular brushing and flossing can help prevent or minimize this side effect. In contrast, choices A, B, and D are not directly related to managing the side effects of Phenytoin. Taking the medication at bedtime (choice A) is not a specific instruction related to oral hygiene. Increasing calcium-rich foods intake (choice B) may be beneficial for bone health but is not directly related to preventing gingival hyperplasia. Avoiding foods high in potassium (choice D) is not a necessary instruction for a client taking Phenytoin.

2. A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?

• A. One
• B. Two
• C. Three
• D. Four

Correct answer: A

Rationale: Phenobarbital, with a long half-life of 4 days, remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should administer phenobarbital once a day to maintain a consistent therapeutic effect without the need for multiple daily doses. Administering the medication more than once a day would not be necessary and could increase the risk of side effects or toxicity. Therefore, the correct answer is to administer phenobarbital once a day.

3. A client has a new prescription for Prednisone. Which of the following instructions should be included in the discharge teaching?

• A. Increase your intake of potassium-rich foods.
• B. Avoid consuming grapefruit juice.
• C. Take this medication with food.
• D. Decrease your intake of sodium-rich foods.

Correct answer: A

Rationale: The correct answer is A: 'Increase your intake of potassium-rich foods.' Prednisone can lead to potassium depletion, making it important for clients to increase their intake of potassium-rich foods like bananas, oranges, and spinach to prevent potential complications. Choice B is incorrect because grapefruit juice can interact with certain medications, but it is not a specific concern with Prednisone. Choice C is incorrect as Prednisone can be taken with or without food. Choice D is also incorrect because there is no direct relationship between Prednisone and sodium-rich foods.

4. Why does a nurse on an oncology unit verify a client's current cumulative lifetime dose of doxorubicin before administering it to a client with breast cancer?

• A. Excessive doxorubicin can result in myelosuppression.
• B. Exceeding the lifetime cumulative dose limit of doxorubicin may lead to extravasation.
• C. An excess amount of doxorubicin can lead to cardiomyopathy.
• D. Exceeding the lifetime cumulative dose limit of doxorubicin may cause red-tinged urine and sweat.

Correct answer: C

Rationale: Verifying the client's current cumulative lifetime dose of doxorubicin is necessary because excessive amounts of the medication can lead to cardiomyopathy, a serious and potentially life-threatening side effect. By monitoring the cumulative dose, healthcare providers can help prevent cardiotoxicity and ensure patient safety during treatment.

5. A healthcare professional is administering a Dopamine infusion at a low dose to a client with severe heart failure. Which of the following findings is an expected effect of this medication?

• A. Lowered heart rate
• B. Increased myocardial contractility
• C. Decreased conduction through the AV node
• D. Vasoconstriction of renal blood vessels

Correct answer: B

Rationale: Dopamine, when administered at a low dose, is expected to increase myocardial contractility by stimulating beta1 receptors. This positive inotropic effect leads to an increase in cardiac output. Therefore, the correct answer is increased myocardial contractility, as it is a desired effect of administering dopamine to a client with severe heart failure.
