Adult Health 2 Final Exam
1. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?
- A. 400 mg/mL
- B. 500 mg/mL
- C. 450 mg/mL
- D. 350 mg/mL
Correct answer: A
Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.
2. The nurse is caring for a client with acute pancreatitis. Which intervention should be included in the plan of care?
- A. Provide a high-protein diet
- B. Encourage oral fluids
- C. Administer intravenous fluids as prescribed
- D. Monitor for signs of hyperglycemia
Correct answer: C
Rationale: The correct intervention to include in the plan of care for a client with acute pancreatitis is to administer intravenous fluids as prescribed. Intravenous fluids are crucial to maintain hydration and electrolyte balance in clients with acute pancreatitis. Providing a high-protein diet (Choice A) is not recommended initially for clients with acute pancreatitis, as they may need to be kept NPO (nothing by mouth) to rest the pancreas. Encouraging oral fluids (Choice B) may not be appropriate if the client is experiencing severe symptoms and requires intravenous fluids. Monitoring for signs of hyperglycemia (Choice D) is important but not the immediate intervention needed to address the fluid and electrolyte imbalances associated with acute pancreatitis.
3. The nurse explains the 2-week dosage prescription of prednisone (Deltasone) to a client who has poison ivy over multiple skin surfaces. What should the nurse emphasize about the dosing schedule?
- A. Decrease the dosage daily as prescribed
- B. Monitor oral temperature daily
- C. Take the prednisone with meals
- D. Return for blood glucose monitoring in one week
Correct answer: A
Rationale: The correct answer is A: 'Decrease the dosage daily as prescribed.' Tapering the dosage of prednisone is crucial to prevent withdrawal symptoms and minimize the side effects of corticosteroid therapy. Decreasing the dosage gradually over time allows the body to adjust and reduces the risk of adrenal insufficiency. Choices B, C, and D are incorrect. Monitoring oral temperature daily, taking prednisone with meals, or returning for blood glucose monitoring in one week are not specific to the dosing schedule of prednisone for poison ivy treatment.
4. A client has a prescription for enteric-coated (EC) aspirin 325mg PO daily. The medication drawer contains one 325mg aspirin. What action should the nurse take?
- A. Contact the pharmacy and request the prescribed form of aspirin
- B. Instruct the client about the effects of the medication
- C. Administer the aspirin with a full glass of water or a small snack
- D. Withhold the aspirin until consulting with the healthcare provider
Correct answer: A
Rationale: The correct action for the nurse to take is to contact the pharmacy and request the prescribed form of aspirin. Enteric-coated medications are designed to dissolve in the intestine, not the stomach, to avoid irritation. Therefore, it is essential to ensure the client receives the correct form of aspirin as prescribed. Instructing the client about the effects of the medication (choice B) is not necessary at this point as the issue is related to the form of the aspirin. Administering the aspirin with a full glass of water or a small snack (choice C) is not appropriate as it does not address the need for the correct form of the medication. Withholding the aspirin (choice D) without consulting the healthcare provider is not advisable as it may lead to a delay in the client receiving the necessary medication.
5. When caring for a client with a tracheostomy, what is the most important assessment to perform?
- A. Check the client's oxygen saturation
- B. Assess the tracheostomy site for signs of infection
- C. Monitor the client's respiratory rate
- D. Ensure the tracheostomy ties are secure
Correct answer: A
Rationale: The most important assessment to perform when caring for a client with a tracheostomy is to check the client's oxygen saturation. This assessment is crucial as it ensures that the client is receiving adequate oxygen through the tracheostomy. Monitoring oxygen saturation provides immediate information on the client's respiratory status and the effectiveness of the airway management. Assessing the tracheostomy site for signs of infection is important but not as critical as ensuring adequate oxygenation. Monitoring the respiratory rate is also essential but does not directly assess the effectiveness of oxygenation. Ensuring tracheostomy ties are secure is important for maintaining the device but does not directly evaluate the client's oxygenation status.
