Nursing Elites

1. Which factors will the nurse consider when calculating the CURB-65 score for a patient with pneumonia? (Select one that does not apply)

• A. Age
• B. Blood pressure
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: D

Rationale: The correct answer is 'Oxygen saturation.' When calculating the CURB-65 score for a patient with pneumonia, the factors considered include mental status (confusion), BUN (elevated), blood pressure (decreased), respiratory rate (increased), and age (65 and older). Oxygen saturation is not used in the CURB-65 scoring system. While blood pressure, respiratory rate, and age are factors that are used in the calculation of the CURB-65 score, oxygen saturation is not part of the scoring criteria. Therefore, oxygen saturation is the factor that does not apply when calculating the CURB-65 score.

2. A man is receiving heparin subcutaneously. The patient has dementia and lives at home with a part-time caretaker. The nurse is most concerned about which side effect of heparin?

• A. Back Pain
• B. Fever and Chills
• C. Risk for Bleeding
• D. Dizziness

Correct answer: C

Rationale: The correct answer is 'Risk for Bleeding.' A patient with dementia may have impaired judgment and may be prone to falls or injuries, increasing the risk of bleeding while on heparin therapy. Monitoring for signs of bleeding is crucial in this situation. Choice A, 'Back Pain,' is not a common side effect of heparin. Choice B, 'Fever and Chills,' is not a typical side effect of heparin but may indicate other underlying conditions. Choice D, 'Dizziness,' is not a common side effect of heparin and is not the primary concern in this scenario.

3. A client is seen for testing to rule out Rocky Mountain Spotted Fever. Which of the following signs or symptoms is associated with this condition?

• A. Fever and rash
• B. Circumoral cyanosis
• C. Elevated glucose levels
• D. All of the above

Correct answer: A

Rationale: The correct answer is 'Fever and rash.' Rocky Mountain Spotted Fever (RMSP) is caused by the R. rickettsii pathogen, which damages blood vessels. Patients with RMSP typically present with fever, edema, and a rash that initially appears on the hands and feet before spreading across the body. The disease manifests following a tick bite. Choice A is correct as fever and rash are key indicators of RMSP. Circumoral cyanosis (choice B) is not typically associated with RMSP; it refers to a bluish discoloration around the mouth and is more indicative of oxygen deprivation. Elevated glucose levels (choice C) are not specific signs of RMSP. Therefore, choice D, 'All of the above,' is incorrect since only choice A, 'Fever and rash,' is associated with Rocky Mountain Spotted Fever.

4. 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.

5. Application - The nurse is caring for a patient who has the following labs: Creatinine 2.5mg/dL, WBC 11,000 cells/mL, and Hemoglobin of 12 g/dL. Based on this information, which of these orders would the nurse question?

• A. Administer 30 Units of Lantus Daily
• B. CT of the spine with contrast
• C. X-ray of the abdomen and chest
• D. Administer heparin subcutaneously 5,000 Units every 12 hours

Correct answer: B

Rationale: The correct answer is to question the order for a CT of the spine with contrast. The patient's elevated creatinine level of 2.5mg/dL indicates impaired kidney function. Contrast agents are nephrotoxic and can further compromise kidney function in patients with existing nephropathy. Therefore, it is crucial to avoid contrast-enhanced imaging studies in patients with impaired renal function. Choice A: Administering 30 Units of Lantus Daily is not contraindicated based on the provided lab values. Choice C: Ordering an X-ray of the abdomen and chest is not contraindicated based on the provided lab values. Choice D: Administering heparin subcutaneously at 5,000 Units every 12 hours is not contraindicated based on the provided lab values.
