A dietitian is providing an in-service for the nurses on a medical-surgical unit. During the in-service, the dietitian informs the group that there are six classes of nutrients, and three supply the body with energy. Which of the following are the three energy-supplying nutrients?
Carbohydrates, proteins, and lipids.
Vitamins, minerals, and water.
Water, lipids, and proteins.
Lipids, vitamins, and minerals.
The Correct Answer is A
The correct answer is choice A, "Carbohydrates, proteins, and lipids." These three nutrients are macronutrients and supply the body with energy when consumed. Carbohydrates provide 4 kilocalories (kcal) per gram, proteins provide 4 kcal per gram, and lipids (fats) provide 9 kcal per gram. Vitamins, minerals, and water are essential for overall health and body function, but they do not supply energy to the same extent as macronutrients.

Correct Answer is C
Explanation
The correct answer is choice C. Call a code and begin resuscitating the client.
In a situation where a client is unresponsive, not breathing, and without a carotid pulse, the priority is to initiate emergency resuscitation measures. The nurse should call a code and begin resuscitating the client immediately, regardless of any prior conversations or wishes that the client may have expressed. If there is no DNR order on the client's chart, it is assumed that the client would want to be resuscitated in such an emergency situation. It is not appropriate for the nurse to make a decision based on a conversation that may or may not have taken place in the past without documentation or a valid DNR order. It is important to act quickly and follow emergency protocols to provide the best chance of survival for the client. After the resuscitation measures have been initiated, the healthcare team can reassess the situation and make decisions based on the client's condition and wishes, if known.
Correct Answer is C
Explanation
Answer and Explanation
The correct answer is choice C, Read back the order to the physician.
After obtaining the physician's order over the phone, the nurse should read back the order to the physician to confirm accuracy and prevent medication errors.
This process ensures that the order is correctly transcribed and the right medication, dose, and route are given to the patient. Calling the pharmacy to check medication availability is not the nurse's responsibility, and initiating the prescription and administering the medication is inappropriate without confirming the order with the physician. Drawing up the medication into an appropriately labeled syringe before confirming the order with the physician is also inappropriate and can lead to medication errors. Therefore, reading back the order to the physician is the most appropriate action for the nurse to take.
