Nursing Elites

1. In what sequence should the nurse prepare the dose of insulin for a client whose finger stick glucose is 210 mg/dl and is receiving a sliding scale dose of short-acting insulin before breakfast?

• A. Clean the vial's rubber stopper with an alcohol swab, withdraw the correct dose of insulin, and then inject air equal to the insulin dose into the vial.
• B. Inject air equal to the insulin dose into the vial, withdraw the correct dose of insulin, and then clean the vial's rubber stopper with an alcohol swab.
• C. Withdraw the correct dose of insulin, inject air equal to the insulin dose into the vial, and then clean the vial's rubber stopper with an alcohol swab.
• D. Clean the vial's rubber stopper with an alcohol swab, inject air equal to the insulin dose into the vial, and then withdraw the correct dose of insulin.

Correct answer: A

Rationale: The correct sequence for preparing a dose of insulin involves ensuring proper aseptic technique. First, clean the vial's rubber stopper with an alcohol swab to prevent contamination. Second, withdraw the correct dose of insulin to be administered. Lastly, inject air equal to the insulin dose into the vial to maintain proper pressure for withdrawing the medication. This sequence ensures the medication is prepared safely and accurately. Choice A is correct as it follows this sequence. Choices B, C, and D present incorrect sequences that may compromise patient safety by not following the correct aseptic technique. Choice B injects air into the vial before withdrawing insulin, which is incorrect. Choice C reverses the order of withdrawing insulin and injecting air. Choice D withdraws the insulin before injecting air, which can affect the pressure inside the vial and lead to inaccurate dosing.

2. After successful resuscitation, a client is given propranolol and transferred to the Intensive Coronary Care Unit (ICCU). On admission, magnesium sulfate 4 grams IV in 250 ml D5W at one gram/hour. Which assessment findings require immediate intervention by the nurse?

• A. Dark amber urine draining via an indwelling catheter at a rate of 40 ml per hour
• B. Serum calcium of 9.0 mg/dl (2.2 mmol/L SI) and magnesium of 1.8 mg/dl or Eq/L (0.74 mmol/L SI)
• C. Sinus rhythm at 72 beats/minute and peripheral blood pressure of 99/62
• D. Respiratory rate of 10 breaths per minute

Correct answer: D

Rationale: The correct answer is D. A low respiratory rate of 10 breaths per minute is indicative of possible magnesium toxicity, which can be a serious condition requiring immediate intervention. It is a critical finding that needs prompt attention to prevent further complications. The other options are not as urgent: A - dark amber urine may indicate dehydration but does not require immediate intervention, B - serum calcium and magnesium levels are within normal limits, C - sinus rhythm and blood pressure values are also within normal range and do not require immediate action.

3. To prevent aspiration in a client on mechanical ventilation receiving continuous enteral feedings through a nasogastric tube, which intervention is most important for the nurse to implement?

• A. Verify the feeding tube position with a daily chest x-ray
• B. Maintain head of bed elevated while enteral feeding is infusing
• C. Check feeding tube placement with air bolus prior to use
• D. Aspirate stomach contents every 4 hours to assess residuals

Correct answer: B

Rationale: The most important intervention to prevent aspiration in a client receiving continuous enteral feedings through a nasogastric tube while on mechanical ventilation is to maintain the head of the bed elevated while the feeding is infusing. This position helps reduce the risk of regurgitation and aspiration. Options A, C, and D are not as crucial as maintaining proper positioning to prevent aspiration. Verifying tube position with a daily chest x-ray is important but not the most crucial. Checking tube placement with an air bolus and aspirating stomach contents are important procedures but do not directly address the prevention of aspiration during enteral feedings.

4. The nurse is assessing an older adult with type 2 diabetes. Which assessment finding indicates that the client understands long-term control of diabetes?

• A. The fasting blood sugar was 120 mg/dL this morning
• B. Urine ketones have been negative for the past 6 months
• C. The hemoglobin A1C was 6.5% last week
• D. No diabetic ketoacidosis has occurred in 6 months

Correct answer: C

Rationale: An A1C level of 6.5% indicates good long-term control of diabetes as it reflects the average blood sugar levels over the past 2-3 months. Monitoring fasting blood sugar provides immediate information about the current blood sugar level, while the absence of urine ketones indicates short-term control. Although the absence of diabetic ketoacidosis is positive, it doesn't specifically reflect long-term control like the A1C level does.

5. When attempting to establish risk reduction strategies in a community, the nurse notes that regional studies indicate a high number of persons with growth stunting and irreversible mental deficiencies caused by hypothyroidism (cretinism). The nurse should seek funding to implement which screening measure?

• A. T3 levels in school-aged children
• B. T4 levels in newborns
• C. TSH levels in women over 45
• D. Iodine levels in all persons over 60

Correct answer: B

Rationale: Screening T4 levels in newborns is crucial as it helps in the early detection of hypothyroidism, which can prevent conditions like cretinism. Checking T3 levels in school-aged children (Choice A) is not the most appropriate measure for early detection of hypothyroidism in newborns. Monitoring TSH levels in women over 45 (Choice C) is not directly related to detecting hypothyroidism in newborns. Additionally, monitoring iodine levels in all persons over 60 (Choice D) is not specifically aimed at early detection of hypothyroidism in newborns, which is crucial to prevent cretinism.
