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 client who is in preterm labor and is receiving magnesium sulfate via IV infusion. Which of the following findings indicates magnesium toxicity?

• A. Blood glucose of 150 mg/dL
• B. Urine output of 20 mL/hour
• C. Systolic blood pressure of 140 mm Hg
• D. BUN 20 mg/dL

Correct answer: B

Rationale: The correct answer is B. A urine output of 20 mL/hour is a sign of magnesium toxicity because decreased urine output can lead to accumulation of magnesium. Choices A, C, and D are not indicators of magnesium toxicity. Elevated blood glucose, high systolic blood pressure, and normal BUN levels do not specifically point towards magnesium toxicity.

3. A nurse is performing a dressing change for a client who has a sacral wound using negative pressure wound therapy. Which of the following actions should the nurse take first?

• A. Apply skin preparation to wound edges
• B. Cleanse the wound with normal saline
• C. Don sterile gloves
• D. Determine the client's pain level

Correct answer: D

Rationale: The correct answer is to determine the client's pain level first. Assessing the client's pain is crucial before proceeding with any procedure, including dressing changes. This step ensures that appropriate pain management measures can be implemented, making the wound care process as comfortable as possible for the patient. Applying skin preparation to wound edges (choice A) can come after addressing the pain. While cleansing the wound with normal saline (choice B) and donning sterile gloves (choice C) are important steps in wound care, they should follow the assessment of the client's pain level to prioritize the patient's comfort and well-being.

4. A newborn demonstrates respiratory distress, and routine suctioning with the bulb syringe is unsuccessful. What is the next nursing intervention?

• A. Initiate chest compressions
• B. Administer oxygen
• C. Suction with a mechanical device
• D. Notify the healthcare provider

Correct answer: C

Rationale: When routine suctioning with a bulb syringe is unsuccessful in a newborn demonstrating respiratory distress, the next appropriate nursing intervention is to suction with a mechanical device. This method ensures effective removal of any airway obstruction. Initiating chest compressions (Choice A) is not indicated in this scenario as the primary concern is airway clearance. Administering oxygen (Choice B) may be necessary, but addressing the airway obstruction should take precedence. Notifying the healthcare provider (Choice D) can be considered after attempting mechanical suction if the newborn's condition does not improve.

5. A nurse is preparing to administer lactated Ringer's (LR) 1,000 mL IV to infuse over 8 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?

• A. 19 gtt/min
• B. 20 gtt/min
• C. 21 gtt/min
• D. 22 gtt/min

Correct answer: C

Rationale: Calculation: 1000 mL / 480 minutes × 10 gtt/mL = 20.83, rounded to 21 gtt/min. This ensures proper IV fluid administration over the prescribed time. Choice C is the correct answer as it reflects the accurate calculation based on the given parameters. Choice A is incorrect because it does not accurately calculate the infusion rate. Choice B is incorrect as it does not consider the precise calculation required. Choice D is incorrect as it deviates from the correct calculation.
