Nursing Elites

1. A physician suspects a patient may have pancreatitis. Which of the following tests would be most appropriate to diagnose this condition?

• A. CK and Troponin
• B. BUN and Creatinine
• C. Amylase and Lipase
• D. HDL and LDL Cholesterol Levels

Correct answer: C

Rationale: To diagnose pancreatitis, testing amylase and lipase levels is crucial. Amylase and lipase are enzymes produced by the pancreas that help digest carbohydrates and lipids. In pancreatitis, these enzymes are released in high amounts into the bloodstream due to pancreatic inflammation or damage. Elevated levels of amylase and lipase in blood tests strongly indicate pancreatitis. Choice A, CK and Troponin, are cardiac markers used in diagnosing heart conditions like myocardial infarction, not pancreatitis. Choice B, BUN and Creatinine, are kidney function tests, not specific to pancreatitis. Choice D, HDL and LDL Cholesterol Levels, are lipid profile tests used to assess cardiovascular health, not for diagnosing pancreatitis.

2. A two-year-old child has sustained an injury to the leg and refuses to walk. The nurse in the emergency department documents swelling of the lower affected leg. Which of the following does the nurse suspect is the cause of the child's symptoms?

• A. Possible fracture of the tibia.
• B. Bruising of the gastrocnemius muscle.
• C. Possible fracture of the radius.
• D. No anatomic injury, the child wants his mother to carry him.

Correct answer: A

Rationale: The child's refusal to walk, along with swelling of the lower leg, indicates a possible fracture, specifically of the tibia. Fractures can cause pain and swelling, leading to difficulty or refusal to bear weight on the affected limb. Choice B, bruising of the gastrocnemius muscle, would not typically result in the child refusing to walk. Choice C, a possible fracture of the radius, is less likely given the location of the swelling and the associated refusal to walk. Choice D, stating no anatomic injury and attributing the child's behavior to wanting to be carried by the mother, is incorrect as the physical findings suggest a potential fracture that needs to be evaluated further.

3. When obtaining a health history and physical assessment for a 36-year-old female patient with possible multiple sclerosis (MS), the nurse should

• A. assess for the presence of chest pain.
• B. inquire about urinary tract problems.
• C. inspect the skin for rashes or discoloration.
• D. ask the patient about any increase in libido.

Correct answer: B

Rationale: When assessing a patient for possible multiple sclerosis (MS), it is important to inquire about urinary tract problems as they are common symptoms of the condition, such as incontinence or retention. Chest pain is not typically associated with MS, so assessing for its presence is not a priority. Inspecting the skin for rashes or discoloration is not a typical manifestation of MS. Additionally, a decrease in libido, rather than an increase, is more commonly seen in patients with MS. Therefore, the most appropriate action for the nurse in this scenario is to inquire about urinary tract problems.

4. 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.

5. What drives respiration in a patient with advanced chronic respiratory failure?

• A. Hypoxemia
• B. Hypocapnia
• C. Hypercapnia
• D. None of the above

Correct answer: A

Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.
