Ms. Collins, a 25-year old female, presents to the Emergency Department (ED) complaining of chest pain and tooth pain. You notice her eyes are bloodshot and she has what appear to be recent track marks from IV drug use on her arms. She is breathing rapidly and seems very uncomfortable. She has very poor dentition and appears to have multiple cavities and broken teeth. She denies any medical history.

What initial nursing assessments need to be performed for Ms. Collins?
Upon further assessment, Ms. Collins’ lungs are clear, pulses are 2+ bilaterally in radial and pedal pulses, S1 and S2 are present with a loud systolic murmur over the mitral and tricuspid valves. She has small bruises on her hands and arms and says her fingers are always cold. She admits to the use of IV heroin and cries that she wants to stop using. Per the provider, you insert a 20g peripheral IV in her left forearm and send a CBC and BMP. Her vital signs are as follows: BP 98/62 mmHg Ht 170 cm HR 92 bpm and regular Wt 55 kg RR 32 bpm SpO2 92% on Room Air Temp 37.9°C Pain 4/10, “comes and goes”

What are your top concerns for Ms. Collins at this time? Why?
She may have some cardiac damage because of her IV drug use. She is breathing rapidly with a moderately low SpO2, so we need to be conscious of her oxygenation. She also reports cold fingers, so we need to monitor perfusion.

What other orders do you anticipate the provider ordering for Ms. Collins?
Perform the 12-lead ECG to rule out an MI (because of her chest pain)
Then, obtain blood cultures before administering antibiotics.
The 12-lead ECG shows normal sinus rhythm at 96 bpm with no ST abnormalities. After drawing blood cultures, you initiate the Vancomycin IVPB. The echocardiogram is completed which shows vegetation on valves and moderate to severe endocarditis with an EF of 50%. She is still complaining of chest pain so you also administer 2 mg Morphine IV push and place her on a bedside monitor. Ms. Collins’s lab results have resulted, the following abnormal values were reported: WBC 23,000/mcL BUN 38 mg/dL Creatinine 2.4 mg/dL Lactate 2.7 mmol/L You return 30 minutes later to take another set of vital signs and find Ms. Collins’ left eye and mouth drooping, she reports a new headache. You notify the provider who orders a STAT Head CT. The scan shows multiple small embolic strokes.

What, physiologically, is going on with Ms. Collins at this time?
Ms. Collins has endocarditis and vegetation on her valves. That vegetation may have broken off and become embolic. She has bruising on her hands which could be embolic complications, and the facial drooping is being caused by the emboli going to her brain and causing small embolic strokes.

What is the likely cause of Ms. Collins’ endocarditis? Explain.
Ms. Collins has a history of IV drug use – this causes bacteria to be introduced directly into the bloodstream She also has apparent dental infections or the possibility of them. This could be another possible source because of the bacteria traveling to the heart.
Ms. Collins is admitted to the cardiac telemetry unit for monitoring and continuous heparin infusion. She is also initiated on three different IV antibiotics to be administered around the clock. After 24 hours, her facial drooping and headache have resolved. Her vital signs are as follows: BP 90/56 mmHg SpO2 94% on 2L nc HR 102 bpm Pain 5/10 chest, comes and goes 3/10 left jaw pain, continuous RR 26 bpm
Doctors determine that Ms. Collins needs to have her mitral valve repaired, but that multiple teeth will need to be pulled first to prevent further infection or complications.

Why might Ms. Collins’ blood pressure still be low at this time?
Bacteria in the oral cavity can travel to the heart very easily. The source of the infection should be removed.
After 3 weeks of IV antibiotics, Ms. Collins is taken to the OR to remove 6 infected molars. She recovers well and is tolerating all antibiotics and medications. Her most recent echocardiogram showed less vegetation and inflammation and an EF of 65%. Three weeks later she has completed a 6-week course of antibiotics and is able to receive a balloon valvuloplasty. She is now ready to be discharged home on clopidogrel (Plavix) and Aspirin.

What education topics would you want to provide to Ms. Collins before discharge?
Lifestyle changes – it is imperative that Ms. Collins stops all IV drug use. This was a major contributor to her development of endocarditis.
Oral health – Ms. Collins needs to be taught proper oral health and should be connected with a community dental provider for follow up.
Medication management – Ms. Collins should be taught signs and symptoms of bleeding and anticoagulant precautions. We should also explain that she needs to take these medications every day as directed and not stop taking them without speaking to her provider
Follow-Up – she needs to see a healthcare provider regularly, including a cardiologist and dental provider. She should avoid any dental procedures for 6 months after discharge.
Infection control – she should be taught how to prevent recurrence and signs and symptoms to report.
This nursing case study course is designed to help nursing students build critical thinking. Each case study was written by experienced nurses with first hand knowledge of the “real-world” disease process. To help you increase your nursing clinical judgement (critical thinking), each unfolding nursing case study includes answers laid out by Blooms Taxonomy to help you see that you are progressing to clinical analysis.We encourage you to read the case study and really through the “critical thinking checks” as this is where the real learning occurs. If you get tripped up by a specific question, no worries, just dig into an associated lesson on the topic and reinforce your understanding. In the end, that is what nursing case studies are all about – growing in your clinical judgement.
