Nursing Elites

1. The healthcare professional is reviewing a patient’s chart prior to administering gentamicin (Garamycin) and notes that the last serum peak drug level was 9 mcg/mL and the last trough level was 2 mcg/mL. What action will the healthcare professional take?

• A. Administer the next dose as prescribed.
• B. Obtain repeat peak and trough levels before administering the next dose.
• C. Report potential drug toxicity to the patient’s healthcare provider.
• D. Notify the patient’s healthcare provider of decreased drug therapeutic level.

Correct answer: C

Rationale: Gentamicin peak levels should ideally be between 5 to 8 mcg/mL, and trough levels should be within the range of 0.5 to 2 mcg/mL to ensure therapeutic efficacy while minimizing toxicity risk. In this case, the patient's peak level is above the recommended range, and the trough level is at the higher end, indicating potential drug toxicity. Therefore, the correct action for the healthcare professional is to report the possibility of drug toxicity to the patient’s healthcare provider. Administering the next dose as prescribed (Choice A) would exacerbate the toxicity risk. Obtaining repeat peak and trough levels (Choice B) may confirm the current levels but does not address the immediate concern of potential toxicity. Reporting a decreased drug therapeutic level (Choice D) is not the priority in this scenario, as the focus should be on addressing the potential toxicity issue.

2. Which of the following is the best indicator of long-term glycemic control in a patient with diabetes?

• A. Fasting blood glucose levels.
• B. Postprandial blood glucose levels.
• C. Hemoglobin A1c.
• D. Random blood glucose levels.

Correct answer: C

Rationale: The correct answer is C, Hemoglobin A1c. Hemoglobin A1c measures the average blood glucose level over the past 2-3 months, providing a reliable indicator of long-term glycemic control. Fasting blood glucose levels (choice A) only offer a snapshot of the current glucose level and can fluctuate throughout the day. Postprandial blood glucose levels (choice B) reflect glucose levels after meals but do not give a comprehensive view of long-term control. Random blood glucose levels (choice D) are taken at any time and lack the consistency needed to assess long-term glycemic control effectively. Therefore, Hemoglobin A1c is the superior choice for monitoring and managing diabetes over an extended period.

3. A client with Diabetes Insipidus (DI) is being cared for by a nurse. Which data warrants the most immediate intervention by the nurse?

• A. Serum sodium of 185 mEq/L (185 mmol/L)
• B. Dry skin with poor skin turgor
• C. Apical rate of 110 beats per minute
• D. Polyuria and excessive thirst

Correct answer: A

Rationale: A serum sodium level of 185 mEq/L (185 mmol/L) is dangerously high and indicates severe dehydration, requiring immediate intervention to prevent neurological damage. The other options are not as critical as high serum sodium levels, which can lead to serious complications such as seizures, coma, and death if not promptly addressed. Dry skin with poor skin turgor and polyuria with excessive thirst are common findings in clients with Diabetes Insipidus and should be managed but do not pose an immediate threat to the client's life. An apical heart rate of 110 beats per minute may indicate tachycardia, which could be related to dehydration but is not as urgent as addressing the severe hypernatremia.

4. A client is receiving a continuous infusion of normal saline at 125 ml/hour post abdominal surgery. The client is drowsy and complaining of constant abdominal pain and a headache. Urine output is 800 ml over the past 24 hours with a central venous pressure of 15 mmHg. The nurse notes respiratory crackles and bounding central pulse. Vital signs: temperature 101.2 F (38.4 C), heart rate 96 beats/minute, respiration 24 breaths/minute, and blood pressure of 160/90 mmHg. Which intervention should the nurse implement first?

• A. Calculate total intake and output for the last 24 hours.
• B. Administer a PRN dose of acetaminophen.
• C. Decrease IV fluids to a keep vein open (KVO) rate.
• D. Review the last administration of IV pain medication.

Correct answer: C

Rationale: In this scenario, the client is showing signs of fluid volume excess, such as drowsiness, abdominal pain, headache, crackles in the lungs, bounding pulse, and elevated blood pressure. Decreasing the IV fluids to a keep vein open (KVO) rate is crucial to prevent further fluid overload. This intervention helps in balancing fluid intake and output to prevent complications associated with fluid volume excess. Calculating total intake and output (Choice A) may be necessary but not the immediate priority in managing fluid overload. Administering acetaminophen (Choice B) may help with managing the fever but does not address the underlying issue of fluid overload. Reviewing the last administration of IV pain medication (Choice D) is not the priority in this situation where fluid overload is a concern.

5. A child who weighs 10 kg will begin taking oral trimethoprim-sulfamethoxazole (TMP-SMX). The liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL. The nurse determines that the child’s dose should be 8 mg of TMP and 40 mg of SMX/kg/day divided into two doses. Which order for this child is correct?

• A. 5 mL PO BID
• B. 5 mL PO daily
• C. 10 mL PO BID
• D. 10 mL PO daily

Correct answer: A

Rationale: The correct answer is A: '5 mL PO BID.' To calculate the child’s daily dose requirement, you multiply the child's weight (10 kg) by the prescribed dosage per kg, which is 8 mg for TMP and 40 mg for SMX. This results in a total daily requirement of 80 mg of TMP and 400 mg of SMX. To divide this into two doses, each dose should contain half of the total daily requirement, which is 40 mg TMP and 200 mg SMX. Since the liquid preparation contains 40 mg of TMP and 200 mg of SMX per 5 mL, the correct dose per administration is 5 mL. Therefore, 5 mL PO BID is the correct order. Choice B, '5 mL PO daily,' is incorrect as the total daily dose needs to be divided into two doses. Choices C and D, '10 mL PO BID' and '10 mL PO daily,' respectively, are incorrect as they do not align with the calculated dosage requirements based on the child's weight and the prescribed dosage per kg.
