Nursing Elites

1. 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.

2. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should the nurse monitor closely?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum calcium level

Correct answer: A

Rationale: In a client with chronic kidney disease (CKD) receiving erythropoietin therapy, the nurse should closely monitor the serum potassium level. Erythropoietin therapy can increase red blood cell production, leading to a higher demand for potassium. Monitoring potassium levels is crucial to prevent hyperkalemia, a potential risk associated with this therapy. Hemoglobin level (Choice B) is important to assess the effectiveness of erythropoietin therapy, but monitoring potassium levels takes precedence due to the risk of hyperkalemia. White blood cell count (Choice C) and serum calcium level (Choice D) are not directly affected by erythropoietin therapy in the context of chronic kidney disease.

3. The nurse is caring for a client with a history of myocardial infarction who is experiencing chest pain. Which intervention should the nurse implement first?

• A. Administer oxygen therapy as prescribed.
• B. Obtain an electrocardiogram (ECG).
• C. Administer nitroglycerin sublingually as prescribed.
• D. Administer aspirin as prescribed.

Correct answer: A

Rationale: Administering oxygen therapy is the priority intervention in managing chest pain in a client with a history of myocardial infarction. Oxygen helps improve oxygenation to the heart muscle, which is crucial in reducing further damage. Obtaining an electrocardiogram (ECG) is important to assess for changes indicative of myocardial infarction, but providing oxygen takes precedence as it directly addresses the physiological need for oxygen. Administering nitroglycerin and aspirin are important interventions but are typically implemented after oxygen therapy to address vasodilation and antiplatelet effects, respectively.

4. In caring for a client with a PCA infusion of morphine sulfate through the right cephalic vein, the nurse assesses that the client is lethargic with a blood pressure of 90/60 mm Hg, a pulse rate of 118 beats per minute, and a respiratory rate of 8 breaths per minute. What assessment should the nurse perform next?

• A. Note the appearance and patency of the client's peripheral IV site.
• B. Palpate the volume of the client's right radial pulse.
• C. Auscultate the client's breath sounds bilaterally.
• D. Observe the amount and dose of morphine in the PCA pump syringe.

Correct answer: D

Rationale: In this scenario, the client is presenting with signs of potential opioid overdose, such as lethargy, hypotension, tachycardia, and bradypnea. The next assessment the nurse should perform is to observe the amount and dose of morphine in the PCA pump syringe. This evaluation is crucial in determining if the client is receiving an excessive amount of morphine, leading to the observed symptoms. Checking the PCA pump syringe will provide essential information to address the client's condition promptly and prevent further complications. Choices A, B, and C are not the priority in this situation as they do not directly address the potential cause of the client's symptoms related to morphine administration.

5. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which laboratory value requires immediate intervention?

• A. Serum glucose of 300 mg/dl
• B. Serum potassium of 5.5 mEq/L
• C. Serum bicarbonate of 18 mEq/L
• D. Serum sodium of 135 mEq/L

Correct answer: C

Rationale: A serum bicarbonate level of 18 mEq/L requires immediate intervention in a client with diabetic ketoacidosis (DKA). A low serum bicarbonate level indicates metabolic acidosis, which can be life-threatening. This condition needs urgent correction to restore acid-base balance. Serum glucose of 300 mg/dl, serum potassium of 5.5 mEq/L, and serum sodium of 135 mEq/L are abnormal values, but they do not pose an immediate threat to the client's life compared to the metabolic acidosis indicated by the low serum bicarbonate level.
