Nursing Elites

1. Following mitral valve replacement surgery, a client develops PVCs. The healthcare provider orders a bolus of Lidocaine followed by a continuous Lidocaine infusion at a rate of 2 mg/minute. The IV solution contains 2 grams of Lidocaine in 500 mL of D5W. The infusion pump delivers 60 microdrops/mL. What rate would deliver 4 mg of Lidocaine per minute?

• A. 60 microdrops/minute
• B. 20 microdrops/minute
• C. 30 microdrops/minute
• D. 40 microdrops/minute

Correct answer: A

Rationale: To calculate the rate needed to deliver 4 mg/minute of Lidocaine, first, convert 2 grams to milligrams: 2 grams = 2000 mg. Then, set up a ratio between the total amount of Lidocaine (2000 mg) and the total volume of IV solution (500 mL): 2000 mg / 500 mL = 4 mg / x mL. Solving for x, x = 1 mL. Since the infusion pump delivers 60 microdrops per mL, multiplying by 60 microdrops/mL gives the correct rate of 60 microdrops/minute. This rate ensures the desired 4 mg of Lidocaine is delivered per minute. Choices B, C, and D are incorrect as they do not align with the accurate calculation based on the provided information.

2. A healthcare professional is reviewing a patient's chart and notices that the patient suffers from conjunctivitis. Which of the following microorganisms is related to this condition?

• A. Yersinia pestis
• B. Helicobacter pylori
• C. Vibrio cholerae
• D. Haemophilus aegyptius

Correct answer: D

Rationale: The correct answer is Haemophilus aegyptius. Haemophilus influenzae biogroup aegyptius (Hae) is a causative agent of acute and often purulent conjunctivitis, more commonly known as pink eye. Yersinia pestis, Helicobacter pylori, and Vibrio cholerae are not associated with conjunctivitis. Yersinia pestis causes the plague, Helicobacter pylori is associated with gastric ulcers, and Vibrio cholerae causes cholera.

3. Which of the following statements made by a client during an individual therapy session would the nurse most identify as reflecting schizoaffective disorder?

• A. ''I just want to stab myself with this pen.''
• B. ''What's the point in life anyways?''
• C. ''My thoughts are racing because of the conspiracies against me.''
• D. ''I hear voices every day and sometimes see old friends that don't exist.''

Correct answer: C

Rationale: The correct answer is, ''My thoughts are racing because of the conspiracies against me.'' Schizoaffective disorder combines the symptoms of bipolar disorder (mania and depression) with those of schizophrenia (delusions and disturbed thought processes). Racing thoughts are a characteristic symptom of a manic episode, while beliefs in conspiracies indicate paranoia, which are common in schizoaffective disorder. Choices A, B, and D do not specifically align with the symptoms of schizoaffective disorder. Choice A suggests self-harm, which may be seen in various mental health conditions; choice B reflects existential questioning or depression; and choice D describes hallucinations, which are more characteristic of schizophrenia rather than schizoaffective disorder.

4. The child with hemolytic-uremic syndrome is anuric and will undergo peritoneal dialysis. Which measure should the nurse implement?

• A. Restrict fluids as prescribed.
• B. Care for the arteriovenous fistula.
• C. Encourage foods high in potassium.
• D. Administer analgesics as prescribed.

Correct answer: A

Rationale: In hemolytic-uremic syndrome, often associated with bacterial toxins and viruses, acute kidney injury occurs in children, leading to symptoms like anemia, thrombocytopenia, renal injury, and CNS symptoms. For an anuric child with hemolytic-uremic syndrome undergoing peritoneal dialysis, fluid restriction is vital to prevent fluid overload. Pain management is not directly related to hemolytic-uremic syndrome. Foods high in potassium should be limited, not encouraged, due to impaired kidney function. Peritoneal dialysis does not involve an arteriovenous fistula, which is specific to hemodialysis.

5. An 85-year-old male has been losing mobility and gaining weight over the last two months. The patient also has the heater running in his house 24 hours a day, even on warm days. Which of the following tests is most likely to be performed?

• A. CBC (complete blood count)
• B. ECG (electrocardiogram)
• C. Thyroid function tests
• D. CT scan

Correct answer: C

Rationale: The symptoms of weight gain and poor temperature tolerance in an elderly male suggest a potential thyroid dysfunction. Thyroid function tests are crucial in differentiating between hyperthyroidism, hypothyroidism, and a euthyroid state. These tests involve measuring the serum levels of thyroid hormones T3 and T4, also known as thyroxine, to evaluate thyroid function accurately. A complete blood count (Choice A) would not directly address the symptoms presented. An electrocardiogram (Choice B) assesses heart activity and would not be the primary test for these symptoms. A CT scan (Choice D) provides detailed images of internal organs and structures, which would not be the initial investigation for the described symptoms.
