Nursing Elites

1. An adolescent client with meningococcal meningitis is receiving a continuous IV infusion of penicillin G. How many mL/hour should the nurse program the infusion pump to deliver?

• A. 83
• B. 85
• C. 87
• D. 90

Correct answer: A

Rationale: The correct answer is A: 83. The pharmacy provided the infusion at 10 million units per liter, which requires a rate of 83 mL/hour. To calculate this, multiply the dosage by the volume of the IV solution and divide by the concentration of the IV solution in million units: 10 million units per liter x 8.3 L = 83 mL/hour. Choices B, C, and D are incorrect as they do not align with the calculation based on the given information.

2. A client with atrial fibrillation is prescribed warfarin. What is the most important instruction the nurse should give?

• A. Take the medication with aspirin to improve effectiveness.
• B. Increase intake of green leafy vegetables to support the medication.
• C. Avoid foods high in potassium to reduce bleeding risk.
• D. Avoid alcohol and over-the-counter medications without consulting the provider.

Correct answer: D

Rationale: The correct answer is D. Clients taking warfarin should avoid alcohol and over-the-counter medications without consulting their healthcare provider, as these can interact with warfarin and increase the risk of bleeding. Aspirin, in particular, can exacerbate this risk. Choice A is incorrect because taking warfarin with aspirin can increase the risk of bleeding. Choice B is incorrect as while green leafy vegetables contain vitamin K which can interact with warfarin, it is more important to maintain a consistent intake rather than increase it. Choice C is incorrect because foods high in potassium do not directly impact the bleeding risk associated with warfarin.

3. A client is admitted with an epidural hematoma after a skateboarding accident. How should the nurse differentiate the vascular source of intracranial bleeding?

• A. Monitor for clear fluid leakage from the nose.
• B. Assess for rapid onset of decreased level of consciousness.
• C. Check for bruising around the head and neck.
• D. Assess for changes in pupil size and reactivity.

Correct answer: B

Rationale: An epidural hematoma is characterized by a rapid onset of symptoms, including decreased level of consciousness, due to arterial bleeding, which differentiates it from other types of intracranial hemorrhage. Monitoring for clear fluid leakage from the nose (choice A) is more indicative of a basilar skull fracture and cerebrospinal fluid leak. Checking for bruising around the head and neck (choice C) is more suggestive of soft tissue injuries or facial fractures. Assessing for changes in pupil size and reactivity (choice D) is essential in evaluating traumatic brain injuries, but it is not specific to differentiating the vascular source of intracranial bleeding in an epidural hematoma.

4. A client with deep vein thrombosis (DVT) is prescribed warfarin. What lab value should the nurse review before administering the medication?

• A. Prothrombin time (PT)
• B. Hemoglobin and hematocrit (H&H)
• C. International Normalized Ratio (INR)
• D. Partial thromboplastin time (PTT)

Correct answer: C

Rationale: The correct answer is C: International Normalized Ratio (INR). Before administering warfarin to a client with deep vein thrombosis, the nurse should review the INR to ensure the client is within the therapeutic range. INR is specifically monitored for patients on warfarin therapy to assess the clotting ability of the blood. Choices A, B, and D are incorrect as they are not the primary lab value used to monitor warfarin therapy. Prothrombin time (PT) is used to measure how long blood takes to clot. Hemoglobin and hematocrit (H&H) assess for anemia and the blood's oxygen-carrying capacity. Partial thromboplastin time (PTT) is used to monitor heparin therapy, not warfarin.

5. A client admitted to the ICU with Syndrome of Inappropriate Antidiuretic Hormone (SIADH) has developed osmotic demyelination. What is the first intervention the nurse should implement?

• A. Evaluate the client's swallowing ability.
• B. Reorient the client frequently.
• C. Patch one eye to minimize confusion.
• D. Perform range of motion exercises.

Correct answer: A

Rationale: The correct answer is to evaluate the client's swallowing ability. Osmotic demyelination can cause dysphagia, putting the client at risk for aspiration. Assessing swallowing function is crucial to prevent complications such as aspiration pneumonia. Reorienting the client frequently (Choice B) is more suitable for confusion related to conditions like delirium. Patching one eye (Choice C) is a technique used for diplopia or double vision, not specifically indicated for osmotic demyelination. Performing range of motion exercises (Choice D) may be beneficial for preventing complications of immobility but is not the priority intervention for osmotic demyelination.
