Nursing Elites

1. Which lab test is used to assess renal function?

• A. Check blood glucose levels
• B. Monitor serum creatinine
• C. Monitor BUN
• D. Check electrolyte levels

Correct answer: B

Rationale: The correct answer is B: Monitor serum creatinine. Serum creatinine is a key indicator of renal function as it reflects the glomerular filtration rate. An increase in serum creatinine levels indicates impaired kidney function. Checking blood glucose levels (choice A) is not specific to assessing renal function but is used to diagnose diabetes. Monitoring BUN (choice C) is important but not as specific as serum creatinine in assessing renal function. Checking electrolyte levels (choice D) is essential in assessing kidney function but is not as specific as monitoring serum creatinine.

2. Which lab value is most critical to monitor in a patient receiving digoxin?

• A. Monitor potassium levels
• B. Monitor sodium levels
• C. Monitor calcium levels
• D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels in a patient receiving digoxin. Hypokalemia can potentiate the toxic effects of digoxin, leading to serious cardiac arrhythmias. Monitoring potassium levels helps prevent toxicity. Monitoring sodium levels (Choice B), calcium levels (Choice C), and magnesium levels (Choice D) are also important aspects of patient care, but potassium levels are most critical in patients on digoxin therapy.

3. Which electrolyte imbalance is common in patients receiving diuretics?

• A. Hypokalemia
• B. Hypercalcemia
• C. Hyponatremia
• D. Hypermagnesemia

Correct answer: A

Rationale: The correct answer is Hypokalemia. Diuretics, such as furosemide, commonly cause potassium loss in patients, leading to hypokalemia. This electrolyte imbalance should be closely monitored to prevent complications like cardiac arrhythmias. Hypercalcemia (Choice B) is not typically associated with diuretic use. Hyponatremia (Choice C) involves low sodium levels and can occur in conditions like syndrome of inappropriate antidiuretic hormone secretion (SIADH) but is not directly caused by diuretics. Hypermagnesemia (Choice D) is an excess of magnesium, usually not a common electrolyte imbalance induced by diuretics.

4. A client who is at 12 weeks of gestation and has hyperemesis gravidarum is being cared for by a nurse. Which of the following laboratory values should the nurse report to the provider?

• A. Sodium 140 mEq/L
• B. Potassium 3.8 mEq/L
• C. Blood glucose 90 mg/dL
• D. Urine ketones present

Correct answer: D

Rationale: The correct answer is D: Urine ketones present. The presence of urine ketones indicates dehydration and inadequate glucose control in clients with hyperemesis gravidarum. Reporting this finding to the provider is crucial for prompt intervention to prevent further complications. Choices A, B, and C are within normal ranges and do not directly correlate with the condition of hyperemesis gravidarum. Therefore, they are not the priority values to report in this scenario.

5. A school nurse is teaching a parent about absence seizures. What information should be included?

• A. This type of seizure lasts 30 to 60 seconds.
• B. This type of seizure can be mistaken for daydreaming.
• C. The child usually has an aura prior to onset.
• D. This type of seizure has a gradual onset.

Correct answer: B

Rationale: The correct answer is B because absence seizures are brief and can be mistaken for daydreaming. Choice A is incorrect because absence seizures typically last a few seconds, not 30 to 60 seconds. Choice C is incorrect as absence seizures usually occur suddenly without an aura. Choice D is incorrect because absence seizures have a sudden onset, not a gradual one.
