Adult Health 2 Final Exam
1. A client is scheduled for an abdominal ultrasound in the morning and has been instructed to fast overnight. The client asks the nurse why fasting is necessary. What is the best response?
- A. It helps reduce the production of intestinal gases.
- B. It ensures clearer imaging by emptying the stomach.
- C. It prevents the risk of aspiration during the procedure.
- D. It is a standard procedure for all surgical interventions.
Correct answer: B
Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.
2. 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.
3. The nurse observes that a male client's urinary catheter (Foley) drainage tubing is secured with tape to his abdomen and then attached to the bed frame. What action should the nurse implement?
- A. Raise the bed to ensure the drainage bag remains off the floor
- B. Attach the drainage bag to the side rail instead of the bed frame
- C. Observe the appearance of the urine in the drainage tubing
- D. Secure the tubing to the client's gown instead of his abdomen
Correct answer: D
Rationale: The correct action for the nurse to implement is to secure the tubing to the client's gown instead of his abdomen. Securing the tubing to the client's abdomen can cause discomfort, trauma to the urethra, and increase the risk of infection. Attaching the drainage bag to the bed frame can lead to tension on the catheter, increasing the risk of dislodgement or trauma. Raising the bed does not address the issue of incorrect tubing securing. Observing the appearance of urine is important but secondary to ensuring proper tubing attachment.
4. A client with asthma is prescribed an albuterol inhaler. Which instruction should the nurse provide?
- A. Use the inhaler only during an asthma attack
- B. Rinse your mouth after using the inhaler
- C. Shake the inhaler before each use
- D. Exhale fully before inhaling the medication
Correct answer: C
Rationale: The correct instruction for the nurse to provide is to shake the inhaler before each use. Shaking the inhaler ensures proper mixing of the medication before administration, which is crucial for its effectiveness. Choice A is incorrect because albuterol inhalers are often used as a preventive measure, not just during asthma attacks. Choice B is a good practice to prevent oral fungal infections associated with inhaled corticosteroids, not typically with albuterol. Choice D is important for proper inhaler technique, but the primary step before inhaling is shaking the inhaler to ensure the medication is well mixed.
5. During a community health fair, a nurse is providing education on the effects of smoking. What is the most important information to include?
- A. Smoking can lead to cosmetic issues like tooth staining.
- B. Smoking is a leading cause of preventable death worldwide.
- C. Smoking temporarily elevates mood and alertness.
- D. Smoking is an expensive habit.
Correct answer: B
Rationale: The correct answer is B: 'Smoking is a leading cause of preventable death worldwide.' This information is crucial as it highlights the severe health risks associated with smoking, emphasizing the importance of cessation for overall health. Choice A is incorrect because cosmetic issues like tooth staining are not as significant as the life-threatening consequences of smoking. Choice C is incorrect because although smoking may temporarily elevate mood and alertness due to nicotine, this does not outweigh the serious health implications. Choice D is incorrect as while smoking is indeed an expensive habit, the focus should be on the health-related consequences to stress the urgency of quitting.
