Nursing Elites

1. A nurse in the telemetry unit is receiving the laboratory findings for an adult male client who is being treated for a myocardial infarction. Which of the following is an expected finding for the client?

• A. Troponin I (TnI) 8 ng/mL
• B. Brain natriuretic peptide (BNP) 10 ng/L
• C. Alanine aminotransferase (ALT) 45 units/L
• D. High-density lipoprotein (HDL) 75 mg/dL

Correct answer: A

Rationale: The correct answer is A. Troponin I is a specific marker for myocardial infarction, and levels of 8 ng/mL are elevated, indicating heart muscle damage. Brain natriuretic peptide (BNP) is more related to heart failure rather than myocardial infarction, making choice B incorrect. Alanine aminotransferase (ALT) is a liver enzyme and not specific to myocardial infarction, so choice C is incorrect. High-density lipoprotein (HDL) is a type of cholesterol and is not typically used to diagnose or monitor myocardial infarction, making choice D incorrect.

2. A nurse is caring for a toddler with respiratory syncytial virus (RSV). Which action should the nurse take?

• A. Use a designated stethoscope for the toddler
• B. Wear an N95 respirator mask when caring for the toddler
• C. Place the toddler in a negative pressure room
• D. Remove the disposable gown before leaving the toddler's room

Correct answer: A

Rationale: Using a designated stethoscope for the toddler is crucial to reduce the risk of spreading RSV to other patients. Choice B is incorrect because N95 respirator masks are not specifically indicated for RSV. Choice C is unnecessary as RSV does not require isolation in a negative pressure room. Choice D is incorrect because the gown should be removed after leaving the room to prevent transmission of pathogens to other areas.

3. A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50, PaCO2 29 mm Hg, and HCO3- 25 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is hyperventilating, leading to excessive elimination of carbon dioxide. As a result, the PaCO2 decreases, causing a decrease in hydrogen ion concentration and an increase in pH, resulting in respiratory alkalosis. Choice A, Respiratory acidosis, is incorrect because the ABG results show a low PaCO2, not an elevated one. Choices C and D, Metabolic acidosis and Metabolic alkalosis, do not align with the ABG results provided, which point towards a respiratory, not metabolic, imbalance.

4. A healthcare professional is preparing to administer heparin 8,000 units subcutaneously every eight hrs. The amount available is heparin injection 10,000 units/mL. How many milliliters should the healthcare professional administer per dose?

• A. 0.7 mL
• B. 0.8 mL
• C. 1.0 mL
• D. 1.2 mL

Correct answer: B

Rationale: Calculation: 8000 units / 10,000 units per mL = 0.8 mL. To correctly administer the prescribed dose of 8000 units, the healthcare professional should draw up 0.8 mL from the 10,000 units/mL vial. Options A, C, and D are incorrect as they do not accurately reflect the calculation based on the available concentration of heparin.

5. A nurse is caring for a client who has an indwelling urinary catheter. What should the nurse identify as a catheter occlusion?

• A. Pain during urination
• B. Bladder distention
• C. Cloudy urine
• D. Blood in the catheter tube

Correct answer: B

Rationale: The correct answer is B: Bladder distention. Bladder distention indicates that the bladder is full and there is impaired elimination, which could be caused by catheter occlusion. Pain during urination (choice A) is not typically associated with catheter occlusion but may indicate a urinary tract infection. Cloudy urine (choice C) can be a sign of infection but is not specific to catheter occlusion. Blood in the catheter tube (choice D) may indicate trauma during catheter insertion but is not a typical finding in catheter occlusion.
