Diabetic ketoacidosis may be caused by
- A. Having too much insulin in the body
- B. Having too little insulin in the body
- C. Eating too little food
- D. Too much exercise
Correct Answer: A
Rationale: Correct Answer: A (Having too much insulin in the body)
Rationale:
1. Insulin deficiency leads to diabetic ketoacidosis.
2. Insulin helps glucose enter cells for energy.
3. Without sufficient insulin, the body breaks down fats for energy, leading to ketone production.
4. Excess insulin can result in hypoglycemia, prompting the body to release stress hormones causing ketoacidosis.
Incorrect Choices:
B: Having too little insulin in the body - This is the opposite of the correct answer.
C: Eating too little food - Insufficient food intake typically leads to hypoglycemia, not ketoacidosis.
D: Too much exercise - Intense exercise can increase ketone levels, but alone is not a primary cause of ketoacidosis.
You are working a respiratory arrest patient and have just successfully placed a combi-tube in your apneic patient. What should you do if the chest fails to rise appropriately and gastric sounds are present?
- A. Secure tube, and ventilate through tube #1
- B. Confirm placement with CO2 detector before ventilating through tube #1
- C. Remove the BVM from tube #1 and ventilate through tube #2
- D. Pull the combi-tube back approximately 2 cm and reassess
Correct Answer: C
Rationale: The correct answer is C: Remove the BVM from tube #1 and ventilate through tube #2. This is the correct action because the presence of gastric sounds indicates that the tube is likely in the esophagus, not the trachea. By removing the BVM from tube #1 and ventilating through tube #2, you are ventilating the patient's lungs directly, improving oxygenation.
Choice A is incorrect because ventilating through tube #1 will not improve the patient's condition if the tube is in the esophagus. Choice B is incorrect because confirming placement with a CO2 detector before ventilating through tube #1 does not address the issue of gastric sounds indicating esophageal placement. Choice D is incorrect because pulling the combi-tube back 2 cm without addressing the issue of esophageal placement will not improve ventilation.
When making a closed bed
- A. one important measure is to
- B. Neatly cover the pillow with the bedspread
- C. Carefully fold linen to one side of the bed
- D. Place the bed in its highest position when finished
Correct Answer: D
Rationale: The correct answer is D because placing the bed in its highest position makes it easier to tuck in the sheets and blankets neatly. This ensures the bed looks tidy and well-made. Choice A is vague and does not specify a particular step for making a closed bed. Choice B is incorrect as the bedspread should be smoothed over the bed, not just covering the pillow. Choice C is also incorrect as folding the linen to one side does not complete the process of making a closed bed.
