Adult Health 1 Exam 1
1. While caring for a client's postoperative dressing, the nurse observes purulent wound drainage. Previously, the wound was inflamed and tender but without drainage. Which is the most important action for the nurse to take?
- A. Determine if the drainage has an unpleasant odor.
- B. Monitor the client's white blood cell count (WBC).
- C. Request a culture and sensitivity of the wound.
- D. Cleanse the wound with a sterile saline solution.
Correct answer: C
Rationale: Requesting a culture and sensitivity of the wound is the most crucial action in this scenario. This will help identify the specific organism causing the infection and determine its sensitivity to antibiotics, guiding appropriate antibiotic therapy. Option A is less critical as odor alone may not provide enough information about the type of infection. Monitoring the client's white blood cell count (WBC) in option B is important but not as immediate as obtaining a wound culture. Cleansing the wound with a sterile saline solution in option D is necessary but should follow after obtaining the culture results to ensure proper treatment.
2. A client with a history of chronic back pain is prescribed oxycodone for pain management. What is the most important instruction the nurse should provide?
- A. Take the medication with food to reduce stomach upset
- B. Avoid operating heavy machinery while taking this medication
- C. Increase physical activity to enhance pain relief
- D. Report any signs of respiratory depression immediately
Correct answer: D
Rationale: The correct answer is D: 'Report any signs of respiratory depression immediately.' Respiratory depression is a severe side effect of opioids like oxycodone and can be life-threatening. It is crucial for the nurse to instruct the client to report any signs such as slow or shallow breathing, difficulty breathing, or confusion. Choice A is incorrect as taking oxycodone with or without food does not significantly affect its efficacy. Choice B is incorrect because avoiding driving is important due to the potential impairment caused by oxycodone, but reporting respiratory depression is more critical. Choice C is incorrect as increasing physical activity may not always be suitable for individuals with chronic back pain and is not directly related to preventing respiratory depression.
3. A 9-year-old is receiving vancomycin 400 mg IV every 6 hours for a methicillin-resistant (Beta-lactam-resistant) Staphylococci aureus (MRSA) infection. The medication is diluted in a 100 mL bag of saline with instructions to infuse over one and a half hours. How many mL/hour should the nurse program the infusion pump?
- A. 50
- B. 67
- C. 57
- D. 70
Correct answer: B
Rationale: To calculate the infusion rate for vancomycin, you need to divide the total volume by the total time of infusion. In this case, the total volume is 100 mL, and the total time is 1.5 hours. Therefore, 100 mL รท 1.5 hours = 67 mL/hour. This means the nurse should program the infusion pump to deliver vancomycin at a rate of 67 mL/hour. Choice A (50) is incorrect as it does not reflect the correct calculation. Choice C (57) is incorrect as it is not the accurate calculation based on the provided information. Choice D (70) is incorrect as it does not correspond to the correct infusion rate calculation.
4. A client with a diagnosis of chronic kidney disease (CKD) is receiving epoetin alfa (Epogen). What is the primary goal of this medication?
- A. To reduce the risk of bleeding.
- B. To lower blood pressure.
- C. To stimulate red blood cell production.
- D. To increase appetite.
Correct answer: C
Rationale: The correct answer is C: 'To stimulate red blood cell production.' Epoetin alfa, such as Epogen, is used to treat anemia by stimulating red blood cell production in clients with chronic kidney disease. This medication helps increase hemoglobin levels and reduce the need for blood transfusions. Option A, 'To reduce the risk of bleeding,' is incorrect as epoetin alfa does not directly impact bleeding risk. Option B, 'To lower blood pressure,' is incorrect as epoetin alfa is not indicated for blood pressure management. Option D, 'To increase appetite,' is also incorrect as the primary goal of epoetin alfa is related to improving anemia by boosting red blood cell production.
5. What are the final factors that contribute to blood pressure? (Select all that apply)
- A. Heart rate
- B. Stroke volume
- C. Peripheral resistance
- D. Neuroendocrine hormones
Correct answer: D
Rationale: Neuroendocrine hormones play a crucial role in regulating blood pressure by influencing factors like fluid balance, blood volume, and vessel constriction. While heart rate, stroke volume, and peripheral resistance are important factors affecting blood pressure, the final parameters that directly produce blood pressure are influenced by neuroendocrine hormones. Therefore, choice D is the correct answer. Choices A, B, and C are involved in the regulation of blood pressure but are not the final parameters that directly produce it.
