Adult Health 1 Exam 1
1. A client is admitted to the hospital with a diagnosis of Pneumonia. Which intervention should the nurse implement to prevent complications associated with Pneumonia?
- A. Encourage mobilization and ambulation
- B. Encourage energy conservation with complete bed rest
- C. Provide humidified oxygen via nasal cannula
- D. Restrict oral (PO) and intravenous fluids
Correct answer: A
Rationale: The correct intervention to prevent complications associated with pneumonia is to encourage mobilization and ambulation. These activities help prevent complications such as atelectasis by promoting lung expansion. Encouraging energy conservation with complete bed rest (Choice B) is not ideal as it can lead to complications like muscle weakness and decreased lung expansion. Providing humidified oxygen via nasal cannula (Choice C) is important in pneumonia treatment but does not directly prevent complications associated with pneumonia itself. Restricting oral (PO) and intravenous fluids (Choice D) is not recommended as adequate hydration is crucial for pneumonia patients to maintain respiratory function and overall health.
2. A client who fell 20 feet from the roof of his home has multiple injuries, including a right pneumothorax. Chest tubes were inserted in the emergency department prior to his transfer to the intensive care unit (ICU). The nurse observes that the suction control chamber is bubbling at the -10 cm H20 mark, with fluctuation in the water seal, and over the past hour, 75 mL of bright red blood is measured in the collection chamber. Which intervention should the nurse implement?
- A. Increase wall suction to eliminate fluctuation in the water seal.
- B. Give blood from the collection chamber as autotransfusion.
- C. Add sterile water to the suction control chamber.
- D. Manipulate blood in tubing to drain into chamber.
Correct answer: C
Rationale: The correct intervention for the nurse to implement is to add sterile water to the suction control chamber. This action helps maintain the proper functioning of the chest tube system by regulating the negative pressure. Increasing wall suction is not recommended as it could lead to excessive negative pressure. Giving blood from the collection chamber as autotransfusion is inappropriate and poses a risk of complications such as air embolism. Manipulating blood in the tubing is also unsafe as it could introduce air into the system, increasing the risk of complications for the client.
3. A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?
- A. Stimulates insulin secretion from the pancreas.
- B. Increases insulin sensitivity in various tissues.
- C. Decreases hepatic glucose production.
- D. Delays absorption of glucose from the intestines.
Correct answer: C
Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.
4. 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.
5. A client with pneumonia is experiencing difficulty expectorating thick secretions. What intervention should the nurse implement to assist the client?
- A. Administer antibiotics as prescribed
- B. Perform chest physiotherapy
- C. Encourage increased fluid intake
- D. Provide humidified oxygen
Correct answer: C
Rationale: The correct intervention for a client experiencing difficulty expectorating thick secretions due to pneumonia is to encourage increased fluid intake. Increasing fluid intake helps to thin secretions, making them easier to expectorate. Administering antibiotics (Choice A) is important in treating pneumonia but does not directly address the issue of thick secretions. Chest physiotherapy (Choice B) may help in some cases, but increasing fluid intake is a more straightforward and effective intervention. Providing humidified oxygen (Choice D) can help with oxygenation but does not directly address the problem of thick secretions.
