Nursing Elites

1. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?

• A. Troponin level of 0.5 ng/mL
• B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
• C. Serum potassium of 4.5 mEq/L
• D. Blood glucose of 180 mg/dL

Correct answer: A

Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.

2. A healthcare professional is measuring vital signs for a client and notices an irregularity in the pulse. Which of the following actions should the healthcare professional take?

• A. Count the apical pulse rate for 1 full minute, and describe the rhythm in the chart.
• B. Recheck the pulse at the same site after 5 minutes.
• C. Measure the client’s blood pressure.
• D. Record the irregularity and continue with other vital signs.

Correct answer: A

Rationale: When an irregular pulse is detected, it is essential to count the apical pulse rate for a full minute to accurately determine the rhythm. This ensures a comprehensive assessment and helps in identifying any potential issues or abnormalities. Rechecking the pulse at the same site after 5 minutes (Choice B) may not provide an immediate understanding of the irregularity. Measuring the client's blood pressure (Choice C) is important but not directly related to addressing the irregular pulse. Recording the irregularity and continuing with other vital signs (Choice D) may overlook a potentially serious cardiac issue that requires immediate attention.

3. The healthcare provider is caring for a 17-month-old with acetaminophen poisoning. Which lab reports should the healthcare provider review first?

• A. Prothrombin time (PT) and partial thromboplastin time (PTT)
• B. Red blood cell and white blood cell counts
• C. Blood urea nitrogen and creatinine levels
• D. Liver enzymes (AST and ALT)

Correct answer: D

Rationale: In acetaminophen poisoning, liver damage is a significant concern due to the toxic effects of the drug on the liver. Liver enzymes such as AST (aspartate aminotransferase) and ALT (alanine aminotransferase) are essential markers to assess liver function and damage. Monitoring these enzymes early is crucial to detect hepatotoxicity and guide further management. Prothrombin time and partial thromboplastin time are coagulation studies and are not the priority in acetaminophen poisoning. Red and white blood cell counts are not specific to assess liver damage in this context. Blood urea nitrogen and creatinine levels are primarily used to evaluate kidney function, which is not the primary concern in acetaminophen poisoning.

4. The client is being taught about the use of syringes and needles for home administration of medications. Which action by the client indicates an understanding of standard precautions?

• A. Remove the needle after discarding used syringes
• B. Wear gloves while disposing of the needle and syringe
• C. Wear a face mask during medication administration
• D. Wash hands before handling the needle and syringe

Correct answer: D

Rationale: The correct answer is D. Washing hands before handling the needle and syringe is a critical step in infection control and adherence to standard precautions. Clean hands help prevent the transfer of microorganisms and reduce the risk of infection. Choices A, B, and C do not directly relate to standard precautions. Removing the needle after discarding used syringes (Choice A) can increase the risk of needlestick injuries. Wearing gloves while disposing of the needle and syringe (Choice B) is important for personal protection but does not specifically address standard precautions. Wearing a face mask during medication administration (Choice C) is not directly related to handling syringes and needles, which are more pertinent to standard precautions.

5. A client is scheduled for an intravenous pyelogram. Which of the following actions is appropriate for the nurse to include?

• A. Monitor the client for pain in the suprapubic region.
• B. Ensure the client is free of metal objects.
• C. Administer 240 mL (8 oz) of oral contrast before the procedure.
• D. Assist the client with a bowel cleansing.

Correct answer: B

Rationale: The correct action for the nurse to include before an intravenous pyelogram is ensuring the client is free of metal objects. Metal objects can interfere with the imaging procedure and may need to be removed to prevent artifacts. Monitoring for pain in the suprapubic region (choice A) is not directly related to the procedure and is not a standard pre-procedure action. Administering oral contrast (choice C) is more common for other imaging studies like a CT scan, not an intravenous pyelogram. Assisting with a bowel cleansing (choice D) is not typically required before an intravenous pyelogram.
