Nursing Elites

1. The nurse is caring for a client with a history of seizure disorder who is receiving phenytoin (Dilantin). Which laboratory value is most important to monitor?

• A. Phenytoin level
• B. Sodium level
• C. Hemoglobin level
• D. White blood cell count

Correct answer: A

Rationale: Corrected Rationale: Monitoring the phenytoin level is crucial to ensure it is within the therapeutic range and to prevent toxicity. Monitoring sodium level is important in clients receiving lithium, not phenytoin. Hemoglobin level and white blood cell count are not directly related to phenytoin therapy monitoring.

2. The nurse is providing discharge instructions to a client with a diagnosis of peptic ulcer disease (PUD). Which dietary recommendation is most appropriate?

• A. Increase fiber intake.
• B. Avoid spicy foods.
• C. Avoid dairy products.
• D. Consume a high-fat diet.

Correct answer: B

Rationale: The most appropriate dietary recommendation for a client with peptic ulcer disease (PUD) is to avoid spicy foods. Spicy foods can irritate the stomach lining and exacerbate symptoms of PUD. Increasing fiber intake may be beneficial for other gastrointestinal conditions but is not the primary concern for PUD. Avoiding dairy products is not a general recommendation for PUD unless the individual has a specific intolerance. Consuming a high-fat diet can increase the risk of exacerbating PUD symptoms due to the delayed gastric emptying associated with high-fat meals.

3. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

4. A new father asks the nurse the reason for placing an ophthalmic ointment in his newborn's eyes. What information should the nurse provide?

• A. Possible exposure to an environmental staphylococcus infection can infect the newborn's eyes and cause visual deficits
• B. The newborn is at risk for blindness from a corneal syphilitic infection acquired from a mother's infected vagina
• C. Treatment prevents tear duct obstruction with harmful exudate from a vaginal birth that can lead to dry eyes in the newborn
• D. State law mandates all newborns receive prophylactic treatment to prevent gonorrheal or chlamydial ophthalmic infection

Correct answer: D

Rationale: The correct answer is D because informing about state law emphasizes the legal requirement and public health rationale behind prophylactic eye treatment to prevent serious infections like gonorrheal or chlamydial ophthalmic infection. Choices A, B, and C are incorrect. Choice A focuses on staphylococcus infection, which is not the primary concern addressed by the prophylactic ointment. Choice B mentions a specific infection acquired from the mother's infected vagina, which is not the main reason for the ophthalmic ointment. Choice C discusses tear duct obstruction and dry eyes, which are not the primary concerns addressed by the prophylactic ointment.

5. When using a metered-dose inhaler (MDI), which step is most important for ensuring effective medication delivery?

• A. Exhale completely before using the inhaler
• B. Inhale quickly while pressing down on the inhaler
• C. Shake the inhaler for 10 seconds before use
• D. Hold breath for 5 seconds after inhaling

Correct answer: A

Rationale: The correct step to ensure effective medication delivery when using a metered-dose inhaler (MDI) is to exhale completely before using the inhaler. This action helps create more space in the lungs for the medication to reach deeply into the airways. Inhaling quickly while pressing down on the inhaler (Choice B) may cause the medication to impact the throat rather than reaching the lungs. Shaking the inhaler for 10 seconds before use (Choice C) is important to mix the medication but not the most crucial step for effective delivery. While holding the breath for 5 seconds after inhaling (Choice D) can help the medication stay in the lungs momentarily, exhaling completely before inhalation is more critical for optimal drug deposition.
