1. A client is receiving a full-strength continuous enteral tube feeding at 50 ml/hour and has developed diarrhea. The client has a new prescription to change the feeding to half strength. What intervention should the nurse implement?
- A. Add equal amounts of water and feeding to a feeding bag and infuse at 50 ml/hour
- B. Continue the full-strength feeding after decreasing the rate of infusion to 25 ml/hour
- C. Maintain the present feeding until diarrhea subsides and then begin the new prescription
- D. Withhold any further feeding until clarifying the prescription with the healthcare provider
Correct answer: A
Rationale: The correct intervention is to dilute the formula by adding equal amounts of water and feeding to a feeding bag and infusing it at 50 ml/hour. This can help alleviate the diarrhea that has developed. Diarrhea can occur as a complication of enteral tube feeding and can be due to a variety of causes, including hyperosmolar formula. Choice B is incorrect as continuing the full-strength feeding, even at a lower rate, may not address the issue of diarrhea. Choice C is incorrect because it is important to follow the new prescription to manage the diarrhea effectively. Choice D is incorrect as withholding feeding without taking appropriate action may delay necessary intervention.
2. The nurse is preparing to administer an enema to a client with severe constipation. Which position is most appropriate for the client?
- A. Supine with the head elevated 30 degrees
- B. Left lateral with the right leg flexed
- C. Sims’ position with the right leg flexed
- D. Prone position with the head turned to the side
Correct answer: C
Rationale: Sims’ position with the right leg flexed is the most appropriate position for administering an enema to a client with severe constipation. This position helps in promoting the flow of the enema solution into the rectum and facilitates the evacuation of stool. Supine position with the head elevated 30 degrees (Choice A) is not ideal for administering an enema as it does not facilitate the flow of the solution. Left lateral position with the right leg flexed (Choice B) is not the best choice for administering an enema. Prone position with the head turned to the side (Choice D) is also not suitable for administering an enema as it does not assist in the proper administration and retention of the solution.
3. The nurse is preparing a 50 ml dose of 50% dextrose IV for a client with insulin shock. What is the most immediate intervention by the nurse?
- A. Dilute the dextrose in one liter of 0.9% Normal Saline solution.
- B. Mix the dextrose in a 50 ml piggyback for a total volume of 100 ml.
- C. Push the undiluted dextrose slowly through the current IV infusion.
- D. Ask the pharmacist to add the dextrose to a TPN solution.
Correct answer: C
Rationale: The correct immediate intervention by the nurse in this situation is to push the undiluted 50% dextrose slowly through the current IV infusion. This is because in cases of insulin shock, where the client has dangerously low blood sugar levels, administering 50% dextrose directly into the bloodstream helps rapidly increase blood glucose levels. Choice A is incorrect because diluting the dextrose in one liter of normal saline would delay the administration of glucose, which is needed urgently. Choice B is incorrect as mixing the dextrose in a piggyback solution would also delay the administration of the concentrated dextrose. Choice D is incorrect because adding dextrose to a TPN solution is not the immediate intervention needed to address the low blood sugar levels in a client experiencing insulin shock.
4. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which clinical finding requires immediate intervention?
- A. Oxygen saturation of 90%
- B. Respiratory rate of 24 breaths per minute
- C. Use of accessory muscles
- D. Inspiratory crackles
Correct answer: C
Rationale: The correct answer is C. The use of accessory muscles in a client with COPD indicates increased work of breathing and may signal respiratory failure, requiring immediate intervention. This finding suggests that the patient is struggling to breathe effectively. Oxygen saturation of 90% is low but not critically low, while a respiratory rate of 24 breaths per minute is slightly elevated but not as concerning as the increased work of breathing indicated by the use of accessory muscles. Inspiratory crackles may be present in COPD due to underlying conditions like pneumonia but do not require immediate intervention as the use of accessory muscles does.
5. A client with a history of chronic heart failure is admitted with shortness of breath. Which diagnostic test should the nurse anticipate preparing the client for first?
- A. Chest X-ray
- B. Arterial blood gases (ABGs)
- C. Echocardiogram
- D. Electrocardiogram (ECG)
Correct answer: C
Rationale: The correct answer is an echocardiogram. This diagnostic test is crucial in assessing ventricular function and identifying the cause of shortness of breath in a client with heart failure. It provides valuable information about the heart's structure, function, and blood flow. While a chest X-ray may show signs of heart failure, it does not directly assess cardiac function like an echocardiogram does. Arterial blood gases (ABGs) are useful to evaluate oxygenation and acid-base balance but do not provide information specific to heart function. An electrocardiogram (ECG) assesses the heart's electrical activity and rhythm, which is important but may not provide the detailed structural information needed in this scenario.
