Adult Health 1 Exam 1
1. The client is diagnosed with pneumonia. Which intervention is most effective in promoting airway clearance?
- A. Administer bronchodilators as prescribed
- B. Encourage increased fluid intake
- C. Perform chest physiotherapy
- D. Provide humidified oxygen
Correct answer: B
Rationale: Encouraging increased fluid intake is the most effective intervention in promoting airway clearance for a client with pneumonia. Increasing fluid intake helps to thin respiratory secretions, making it easier for the client to clear the airways. Administering bronchodilators may help with bronchospasm but does not directly promote airway clearance. Chest physiotherapy may be beneficial but is not the first-line intervention for promoting airway clearance in pneumonia. Providing humidified oxygen can improve oxygenation but does not directly address airway clearance.
2. The nurse is caring for a client who underwent a total knee replacement yesterday. What activity level should the nurse encourage today?
- A. Bed rest with bathroom privileges only
- B. Frequent, short walks with assistance
- C. Range of motion exercises to the knee every four hours
- D. Leg elevation to reduce swelling
Correct answer: B
Rationale: After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.
3. 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.
4. The nurse is caring for a client with chronic liver disease. Which lab value is most concerning?
- A. Elevated AST and ALT
- B. Decreased albumin level
- C. Elevated bilirubin level
- D. Prolonged PT/INR
Correct answer: D
Rationale: The correct answer is D, prolonged PT/INR. In a client with chronic liver disease, a prolonged PT/INR is the most concerning lab value. This indicates impaired liver function, leading to a higher risk of bleeding. Elevated AST and ALT (choice A) are indicators of liver damage but do not directly assess the risk of bleeding. Decreased albumin level (choice B) reflects impaired liver function but is not as directly related to bleeding risk as a prolonged PT/INR. Elevated bilirubin level (choice C) is a sign of liver dysfunction, specifically related to bile metabolism, and while important, it is not as directly associated with bleeding risk as a prolonged PT/INR in the context of chronic liver disease.
5. A client with type 1 diabetes 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 priority intervention for a client with type 1 diabetes experiencing symptoms of hypoglycemia is to give 15 grams of a fast-acting carbohydrate. In a hypoglycemic state, the priority is to quickly raise the blood glucose level. Administering glucagon intramuscularly (Choice A) is reserved for severe hypoglycemia when the client is unable to take oral carbohydrates. Providing a complex carbohydrate snack (Choice B) is beneficial after the initial treatment of hypoglycemia to prevent recurrence. Administering 50% dextrose intravenously (Choice C) is a more invasive intervention typically done in a hospital setting for severe cases.
