Nursing Elites

1. What instruction should the nurse include for a client prescribed nitroglycerin for a myocardial infarction?

• A. Take the medication only when experiencing severe chest pain.
• B. Store the medication in a dark container to protect it from light.
• C. Take the medication before engaging in physical activity that may trigger chest pain.
• D. Limit nitroglycerin use to no more than three doses in 15 minutes.

Correct answer: D

Rationale: The correct answer is D: 'Limit nitroglycerin use to no more than three doses in 15 minutes.' This instruction is crucial to prevent excessive use, which can lead to severe hypotension and other complications. Choice A is incorrect because nitroglycerin should also be used preventatively, not only during severe chest pain. Choice B is irrelevant and not a necessary instruction for nitroglycerin use. Choice C is incorrect as nitroglycerin is typically taken to prevent chest pain rather than waiting for an activity that may trigger it.

2. A client is receiving continuous intravenous heparin for a deep vein thrombosis. Which laboratory result should the nurse monitor to ensure therapeutic heparin levels?

• A. International normalized ratio (INR)
• B. Activated partial thromboplastin time (aPTT)
• C. Hemoglobin
• D. Platelet count

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is the most accurate measure of heparin's therapeutic effect. Heparin increases the time it takes for blood to clot, and the aPTT helps determine whether the dose is within the desired range for anticoagulation therapy. Monitoring the INR, hemoglobin, or platelet count is not specific to assessing therapeutic heparin levels and may not reflect the anticoagulant effect of heparin.

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 congestive heart failure is prescribed digoxin. What symptom indicates digoxin toxicity?

• A. Monitor for muscle weakness and fatigue.
• B. Monitor for increased appetite and weight gain.
• C. Monitor for nausea and vomiting.
• D. Monitor for blurred vision or seeing yellow halos around objects.

Correct answer: D

Rationale: Corrected Rationale: Blurred vision or seeing yellow halos around objects are signs of digoxin toxicity, which can be life-threatening. These symptoms indicate an overdose of digoxin, requiring immediate medical attention. Muscle weakness and fatigue (Choice A) are not typically associated with digoxin toxicity. Increased appetite and weight gain (Choice B) are not indicative of digoxin toxicity either. Nausea and vomiting (Choice C) are common side effects of digoxin but are not specific signs of toxicity. Therefore, the correct answer is to monitor for blurred vision or seeing yellow halos around objects.

5. A client with a history of stroke is receiving warfarin. What is the nurse's priority assessment?

• A. Check the client's blood pressure.
• B. Assess for signs of bleeding.
• C. Assess the client's neurological status.
• D. Monitor the client's intake and output.

Correct answer: B

Rationale: The correct answer is to assess for signs of bleeding. Warfarin is an anticoagulant that increases the risk of bleeding in patients. Monitoring for signs of bleeding such as easy bruising, petechiae, blood in urine or stool, or unusual bleeding from gums is crucial. Checking the client's blood pressure (choice A) is important but not the priority in this situation. Assessing the client's neurological status (choice C) is essential in stroke patients but is not the priority related to warfarin therapy. Monitoring intake and output (choice D) is important for overall assessment but is not the priority when a client is on warfarin, as assessing for bleeding takes precedence.
