Nursing Elites

1. A client with a history of chronic kidney disease (CKD) is admitted with hyperkalemia. Which clinical finding is most concerning?

• A. Peaked T waves on the ECG
• B. Bradycardia
• C. Muscle weakness
• D. Decreased deep tendon reflexes

Correct answer: A

Rationale: Peaked T waves on the ECG are the most concerning finding in a client with hyperkalemia. Hyperkalemia can lead to serious cardiac complications, including arrhythmias and cardiac arrest. Peaked T waves are a classic ECG finding associated with hyperkalemia and indicate the need for immediate intervention. Bradycardia, muscle weakness, and decreased deep tendon reflexes can also be seen in hyperkalemia, but the presence of peaked T waves signifies a higher risk of cardiac events, making it the most concerning finding in this scenario.

2. A client who is at 36 weeks gestation is admitted with severe preeclampsia. After a 6-gram loading dose of magnesium sulfate is administered, an intravenous infusion of magnesium sulfate at a rate of 2 grams/hour is initiated. Which assessment finding warrants immediate intervention by the nurse?

• A. Urine output of 20 ml/hour
• B. Blood pressure of 138/88
• C. Respiratory rate of 18 breaths/min
• D. Temperature of 99.8°F

Correct answer: A

Rationale: A urine output of less than 30 ml/hour indicates that the kidneys are being affected by the high level of magnesium sulfate. This decreased urine output can lead to magnesium toxicity and impaired kidney function. Blood pressure of 138/88 is within normal limits for pregnancy and does not indicate an immediate concern related to magnesium sulfate. A respiratory rate of 18 breaths/min is normal, and a temperature of 99.8°F is slightly elevated but not a priority in the context of severe preeclampsia and magnesium sulfate administration.

3. The healthcare provider prescribes ceftazidime (Fortaz) 35 mg every 8 hours IM for an infant. The 500 mg vial is labeled with the instruction to add 5.3 ml diluent to provide a concentration of 100 mg/ml. How many ml should the nurse administer for each dose?

• A. 0.35 ml
• B. 0.40 ml
• C. 0.50 ml
• D. 0.45 ml

Correct answer: B

Rationale: To calculate the volume to be administered for 35 mg of ceftazidime, divide the prescribed dose by the concentration: 35 mg / 100 mg/ml = 0.35 ml. Rounding off, the nurse should administer 0.4 ml for each dose. Choice A is incorrect as it doesn't consider rounding off. Choice C is incorrect because it's not the correct calculation. Choice D is incorrect as it doesn't reflect the accurate volume needed.

4. When caring for a client with traumatic brain injury (TBI) who had a craniotomy for increased intracranial pressure (ICP), the nurse assesses the client using the Glasgow Coma Scale (GCS) every two hours. For the past 8 hours, the client's GCS score has been 14. What does this GCS finding indicate about the client?

• A. Neurologically stable without indications of increased ICP.
• B. At risk for neurological deterioration.
• C. Experiencing mild cognitive impairment.
• D. In need of immediate medical intervention.

Correct answer: A

Rationale: A GCS score of 14 indicates that the client is neurologically stable without indications of increased ICP. It suggests that the client's neurological status is relatively intact, with only mild impairment, if any. This finding reassures the nurse that there are currently no signs of deterioration or immediate need for intervention. Choice B is incorrect because a GCS score of 14 does not necessarily indicate immediate risk for neurological deterioration. Choice C is incorrect as mild cognitive impairment is not typically inferred from a GCS score of 14. Choice D is incorrect as immediate medical intervention is not warranted based on a GCS score of 14 without other concerning symptoms.

5. The healthcare provider should observe most closely for drug toxicity when a client receives a medication that has which characteristic?

• A. Low bioavailability
• B. Rapid onset of action
• C. Short half-life
• D. Narrow therapeutic index

Correct answer: D

Rationale: The correct answer is D, narrow therapeutic index. Narrow therapeutic index (NTI) drugs are defined as those drugs where small differences in dose or blood concentration may lead to serious therapeutic failures or adverse drug reactions. Choices A, B, and C are not directly related to the risk of drug toxicity. Low bioavailability (Choice A) refers to the amount of drug that enters the bloodstream unchanged after administration. Rapid onset of action (Choice B) and short half-life (Choice C) are characteristics related to drug effectiveness and metabolism but do not necessarily indicate a higher risk of drug toxicity.
