Nursing Elites

1. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

2. A nurse is admitting a client who has anorexia nervosa. Which of the following is an expected finding?

• A. Iron 90 mcg/dl.
• B. Prealbumin 10 mcg/dl.
• C. Serum creatinine 0.8 mg/dl.
• D. Calcium 9.5 mg/dl.

Correct answer: B

Rationale: Corrected Rationale: Low prealbumin levels are indicative of malnutrition, which is common in individuals with anorexia nervosa. Iron levels, serum creatinine, and calcium levels are not typically affected in the same way by anorexia nervosa, making choices A, C, and D incorrect.

3. A nurse is caring for a client who is 2 hours postoperative following a colon resection. Which of the following assessments is the nurse's priority?

• A. Capillary refill
• B. Bowel sounds
• C. Temperature
• D. Oxygen saturation

Correct answer: D

Rationale: The correct answer is D: Oxygen saturation. The priority assessment in this situation is oxygen saturation because postoperative clients are at risk for respiratory complications, such as hypoxia due to factors like anesthesia effects, impaired lung function, or pain interfering with deep breathing. Monitoring oxygen saturation is crucial to detect any respiratory compromise early. Capillary refill, bowel sounds, and temperature are important assessments but are not the priority in this immediate postoperative period.

4. How should a healthcare professional manage a patient with suspected myocardial infarction (MI)?

• A. Administer oxygen and call for emergency help
• B. Monitor vital signs and provide pain relief
• C. Provide nitroglycerin and thrombolytics
• D. Administer diuretics and provide a high-protein diet

Correct answer: A

Rationale: Administering oxygen and seeking emergency help are crucial initial steps in managing a patient with suspected myocardial infarction (MI). Oxygen helps to improve oxygenation to the heart muscle, reducing its workload and preventing further damage. Calling for emergency help ensures timely access to advanced medical care, including interventions like thrombolytics. Monitoring vital signs and providing pain relief are important but secondary to the immediate need for oxygen and emergency assistance. Providing nitroglycerin and thrombolytics should be done under medical supervision and following appropriate protocols, not as the first step. Administering diuretics and altering the patient's diet are not indicated in the acute management of MI.

5. When providing discharge instructions for a client prescribed home oxygen, what is an essential safety measure?

• A. Ensure the client has cotton bedding
• B. Keep the oxygen equipment away from heat sources
• C. Use wool blankets to ensure warmth
• D. Allow the client to use electronic devices near the oxygen supply

Correct answer: B

Rationale: The correct answer is B: 'Keep the oxygen equipment away from heat sources.' Placing oxygen equipment near heat sources can lead to fire hazards due to the flammability of oxygen. Cotton bedding or wool blankets are not directly related to oxygen safety measures. Allowing electronic devices near the oxygen supply can increase the risk of fire due to potential sparks or heat generated.
