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 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.
3. The nurse is providing discharge teaching to a client with newly diagnosed type 2 diabetes mellitus. Which instruction is most important to prevent complications?
- A. Monitor blood glucose levels regularly
- B. Maintain a low-fat diet
- C. Exercise regularly
- D. Take medication as prescribed
Correct answer: A
Rationale: Regular monitoring of blood glucose levels is crucial in managing diabetes and preventing complications. This allows the client and healthcare team to make timely adjustments to the treatment plan. While maintaining a low-fat diet, exercising regularly, and taking medication as prescribed are all important aspects of diabetes management, monitoring blood glucose levels takes precedence as it provides real-time information about the client's condition and helps prevent acute complications.
4. The nurse assigns an unlicensed assistive personnel (UAP) to feed a client who is at risk for aspiration. What action should the nurse take to ensure safety?
- A. Inform the UAP that suction is available at the bedside.
- B. Instruct the UAP to notify the nurse if the client chokes.
- C. Observe the UAP's ability to implement precautions during feeding.
- D. Ask the UAP about previous experience in performing this skill.
Correct answer: C
Rationale: Observing the UAP's ability to implement precautions during feeding is crucial to ensuring the client's safety, especially when there is a risk of aspiration. This hands-on observation allows the nurse to assess whether the UAP is competent in handling the feeding procedure safely. Informing the UAP about suction availability (Choice A) is important but does not directly assess the UAP's ability during feeding. Instructing the UAP to notify the nurse if the client chokes (Choice B) focuses on reactive measures rather than proactive supervision. Asking about previous experience (Choice D) does not provide real-time information on the UAP's current competency in handling the specific feeding task for the at-risk client.
5. A client with a diagnosis of diabetes mellitus is experiencing symptoms of hypoglycemia. What is the nurse's priority intervention?
- A. Administer glucagon intramuscularly.
- B. Provide a complex carbohydrate snack.
- C. Administer 50% dextrose intravenously.
- D. Give 15 grams of a fast-acting carbohydrate.
Correct answer: D
Rationale: The correct answer is to give 15 grams of a fast-acting carbohydrate as the priority intervention in a client experiencing hypoglycemia. This helps quickly raise the blood glucose level. Administering glucagon intramuscularly (Choice A) is typically reserved for severe hypoglycemia where the client is unable to take oral carbohydrates. Providing a complex carbohydrate snack (Choice B) is not the priority in an acute hypoglycemic episode where immediate action is needed. Administering 50% dextrose intravenously (Choice C) is more invasive and usually reserved for cases where the client is unable to take anything by mouth.
