1. Which serum blood finding in diabetic ketoacidosis alerts the nurse that immediate action is required?
- A. pH below 7.3
- B. Potassium of 5.0
- C. HCT of 60
- D. PaO2 of 79%
Correct answer: C
Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.
2. While measuring a client’s vital signs, the nurse notices an irregularity in the heart rate. Which nursing action is appropriate?
- A. Count the apical pulse rate for 1 full minute, and describe the rhythm in the chart
- B. Measure the blood pressure
- C. Perform an ECG
- D. Recheck the heart rate after 5 minutes
Correct answer: A
Rationale: The appropriate nursing action when an irregularity in the heart rate is observed is to count the apical pulse rate for a full minute and describe the rhythm in the chart. This approach helps in obtaining an accurate assessment of the irregularities present. Measuring the blood pressure (Choice B) is important but not the immediate priority when an irregular heart rate is noted. Performing an ECG (Choice C) may be necessary but is a more advanced intervention that should follow the initial assessment. Rechecking the heart rate after 5 minutes (Choice D) may delay potential interventions for addressing the irregularity, making it less appropriate than the immediate assessment and documentation of the pulse rhythm.
3. The patient refuses a morning bath, stating a preference for evening baths. What is the best action for the nurse to take?
- A. Defer the bath until evening and pass on the information to the next shift.
- B. Tell the patient that daily morning baths are the 'normal' routine.
- C. Explain the importance of maintaining morning hygiene practices.
- D. Cancel hygiene for the day and attempt again in the morning.
Correct answer: A
Rationale: The best action for the nurse is to respect the patient's preference and autonomy. By deferring the bath until evening, the nurse acknowledges and accommodates the patient's routine, promoting patient-centered care. Choice B could be seen as dismissive of the patient's preference and may not foster a therapeutic relationship. Choice C, while important, doesn't address the patient's current refusal. Choice D is not respectful of the patient's autonomy and could lead to increased resistance. Therefore, option A is the most appropriate and patient-centered approach.
4. A client who is unstable and requires frequent vital signs has an electronic blood pressure machine automatically measuring his blood pressure every 15 min. However, the machine is reading the client’s blood pressure at more frequent intervals, and the readings are not similar. The nurse checks the machine settings and observes the additional readings, but the problem continues. Which of the following is the appropriate nursing action?
- A. Notify the manufacturer
- B. Disconnect the machine, and measure the blood pressure manually every 15 min
- C. Adjust the machine settings again
- D. Ignore the extra readings
Correct answer: B
Rationale: The correct action in this scenario is to disconnect the electronic blood pressure machine and measure the client's blood pressure manually every 15 minutes. Given that the machine is malfunctioning and providing inconsistent readings, relying on manual measurements ensures accuracy and maintains the quality of care. Notifying the manufacturer (Choice A) may be necessary in the long run, but the immediate concern is the accuracy of the vital signs. Adjusting the machine settings again (Choice C) without resolving the underlying issue would not address the problem. Ignoring the extra readings (Choice D) could lead to incorrect assessment and compromise patient care. Therefore, the best course of action is to disconnect the machine and opt for manual blood pressure measurements until the issue is resolved.
5. A client is being taught how to care for their tracheostomy at home. Which of the following instructions should the nurse include in the teaching?
- A. Use tracheostomy covers when outdoors.
- B. Clean the tracheostomy site with hydrogen peroxide daily.
- C. Change the tracheostomy tube weekly.
- D. Apply ointment around the tracheostomy site.
Correct answer: A
Rationale: The correct instruction is to use tracheostomy covers when outdoors. Tracheostomy covers serve to protect the airway from environmental contaminants, reducing the risk of infection. Choice B is incorrect because hydrogen peroxide can be irritating to the skin and is not recommended for cleaning the tracheostomy site. Choice C is incorrect as tracheostomy tubes should not be routinely changed weekly unless there is a specific medical indication. Changing it without a need can introduce infection or damage the stoma. Choice D is incorrect as applying ointment around the tracheostomy site can lead to occlusion of the stoma and interfere with breathing.
