Nursing Elites

1. The nurse is caring for a client with a suspected myocardial infarction (MI). Which laboratory test result is most indicative of a recent MI?

• A. Elevated troponin levels
• B. Increased white blood cell count
• C. Increased lactate dehydrogenase (LDH)
• D. Elevated C-reactive protein (CRP)

Correct answer: A

Rationale: Elevated troponin levels are the most specific and sensitive indicator of myocardial infarction. Troponin levels increase within hours of an MI and remain elevated for several days. White blood cell count, lactate dehydrogenase (LDH), and C-reactive protein (CRP) are not specific markers for MI. An increased white blood cell count may indicate inflammation or infection, increased LDH levels can be seen in various conditions like liver disease or muscle injury, and elevated CRP is a general marker of inflammation rather than specific to MI.

2. A client who gave birth 48 hours ago has decided to bottle-feed the infant. The nurse observes that both breasts were swollen, warm, and tender on palpation during the assessment. Which instruction should the nurse provide?

• A. Take warm showers to reduce swelling
• B. Wear a tight-fitting bra for support
• C. Apply ice to the breasts for comfort
• D. Express milk manually to relieve discomfort

Correct answer: C

Rationale: The correct answer is to advise the client to apply ice to the breasts for comfort. Applying ice can help reduce swelling and discomfort associated with engorgement in a woman who is not breastfeeding. Expressing milk manually would stimulate further milk production, which is not desired in this case. Wearing a tight bra could increase discomfort by putting pressure on the engorged breasts. Warm showers may actually increase swelling due to the vasodilation effect of heat.

3. A male client with schizophrenia is socially reclusive and pacing in the hallway. What is the most important intervention for the nurse to implement?

• A. Take the client's temperature and blood pressure.
• B. Encourage the client to rest.
• C. Plan an activity that includes physical exercise.
• D. Carefully observe the client throughout the shift.

Correct answer: D

Rationale: The correct answer is to carefully observe the client throughout the shift. In this situation, the client's behavior suggests agitation and restlessness, which could potentially escalate. Observation is crucial to monitor any changes in behavior, assess for signs of distress, and ensure the client's safety. Taking the client's temperature and blood pressure (Choice A) may not address the immediate need for managing the client's behavior. Encouraging the client to rest (Choice B) might not be effective if the client is highly agitated. Planning an activity that includes physical exercise (Choice C) could exacerbate the situation rather than address the current behavior. Therefore, the priority is to observe the client closely to provide appropriate support and intervention as needed.

4. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

5. What is the first action the nurse should take when treating a 6-year-old child who stepped on a rusty nail?

• A. Cleanse the foot with soap and water
• B. Instruct the parent about tetanus boosters
• C. Apply a sterile dressing and refer for a tetanus booster
• D. Elevate the foot and wrap in a compression bandage

Correct answer: B

Rationale: The correct first action when a 6-year-old child steps on a rusty nail is to instruct the parent about tetanus boosters. This is important because stepping on a rusty nail increases the risk of tetanus infection. Choice A is incorrect as cleansing the foot comes after addressing the tetanus risk. Choice C is not the first action and should be done after addressing the immediate risk of tetanus. Choice D is not necessary as the priority is to prevent tetanus infection.
