Nursing Elites

1. A client has an infection and a prescription for gentamicin intermittent IV bolus every 8 hr. A peak and trough is required with the next dose. Which of the following actions should be taken to obtain an accurate gentamicin serum level?

• A. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
• B. Draw a peak level 90 min prior to administering the medication and a trough level 90 min after the dose.
• C. Draw a trough level immediately prior to administering the medication and a peak level 30 min after the dose.
• D. Draw a peak level at 0900 and a trough level at 2100.

Correct answer: C

Rationale: To obtain an accurate gentamicin serum level, the trough should be drawn immediately before administering the medication, and the peak level should be drawn 30 minutes after the dose. This timing allows for the assessment of the lowest and highest drug concentrations in the bloodstream, ensuring therapeutic levels are achieved while minimizing the risk of toxicity. Choice A is correct as it follows this timing protocol. Choices B and D have incorrect timing for peak and trough levels, which would not provide an accurate representation of the drug's concentration in the bloodstream.

2. A client is taking Epoetin Alfa for anemia. Which of the following laboratory tests should the nurse monitor to evaluate the effectiveness of the therapy?

• A. White blood cell count
• B. Platelet count
• C. Hematocrit
• D. Serum potassium level

Correct answer: C

Rationale: The nurse should monitor the hematocrit level to evaluate the effectiveness of Epoetin Alfa therapy since it stimulates red blood cell production. Hematocrit reflects the volume of red blood cells in the blood, providing a direct measure of the therapy's impact on increasing red blood cell mass and addressing anemia. Monitoring white blood cell count and platelet count is not directly related to assessing the effectiveness of Epoetin Alfa therapy for anemia. Serum potassium level monitoring may be necessary due to potential side effects of the medication, but it is not the primary indicator of therapy effectiveness in treating anemia.

3. A client is receiving vancomycin. Which of the following laboratory results should be monitored to evaluate the therapeutic effect of this medication?

• A. BUN
• B. Creatinine
• C. Hemoglobin
• D. White blood cell count

Correct answer: B

Rationale: Corrected Rationale: Creatinine levels should be monitored to evaluate vancomycin's effect on kidney function. Vancomycin can be nephrotoxic, so monitoring creatinine levels helps assess renal function and ensure that the medication is not causing harm to the kidneys. Monitoring BUN (choice A) is important for assessing kidney function but is not as specific as monitoring creatinine levels. Hemoglobin (choice C) and white blood cell count (choice D) are not directly related to evaluating the therapeutic effect of vancomycin.

4. When administering subcutaneous enoxaparin 40 mg using a prefilled syringe of Enoxaparin 40 mg/0.4 mL to an adult client following hip arthroplasty, what action should the nurse plan to take?

• A. Expel any air bubbles from the prefilled syringe before injecting.
• B. Insert the needle completely into the client's tissue.
• C. Administer the injection in the client's thigh.
• D. Aspirate carefully after inserting the needle into the client's skin.

Correct answer: B

Rationale: When administering enoxaparin via a prefilled syringe for deep subcutaneous injection, the nurse should insert the needle completely into the client's tissue. This action ensures proper delivery of the medication into the subcutaneous layer, promoting optimal therapeutic effects. Choice A is incorrect because there is no need to expel air bubbles from a prefilled syringe. Choice C is incorrect as enoxaparin is typically administered in the abdomen for subcutaneous injections. Choice D is incorrect as aspiration is not recommended for subcutaneous injections to avoid trauma or damage to tissues.

5. When should Montelukast be taken?

• A. At least two hours before exercise
• B. Daily in the evening
• C. Two hours before exercise or daily in the evening
• D. None of the above

Correct answer: B

Rationale: Montelukast should be taken daily in the evening to effectively manage asthma symptoms. Taking it at the same time each day helps maintain a consistent level of the medication in the body, providing optimal control over asthma symptoms and inflammation. Choice A is incorrect because Montelukast should not be taken specifically before exercise, but rather daily. Choice C is incorrect because although taking Montelukast two hours before exercise is not necessary, taking it daily in the evening is essential for its effectiveness. Choice D is incorrect as Montelukast should be taken daily to manage asthma.
