1. When admitting a 5-month-old who has vomited 9 times in the past 6 hours, what should the healthcare provider observe for signs of which overall imbalance?

Correct answer: B

Rationale: When a 5-month-old infant vomits multiple times, there is a risk of developing metabolic alkalosis due to the loss of stomach acid. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. It is caused by the loss of hydrogen ions from the body, often through vomiting. Metabolic acidosis (choice A) is unlikely in this scenario because it is more commonly associated with conditions like renal failure or diabetic ketoacidosis. Choice C, increased serum hemoglobin levels, is not typically a direct consequence of vomiting. Choice D, decreased serum potassium levels, may occur with vomiting but is not the primary concern when a patient is vomiting excessively.

2. While being prepared for transport to the operating room, a client scheduled for hysterectomy informs the nurse that she no longer wants to have surgery. What action should the nurse take?

Correct answer: A

Rationale: The correct action for the nurse to take in this situation is to notify the provider about the client's decision. By informing the provider, they can discuss the client's change in decision, explore the reasons behind it, and determine the appropriate course of action. Proceeding with the transport (Choice B) without addressing the client's concerns would not respect the client's autonomy and right to make decisions about their own healthcare. Preparing the surgical site (Choice C) would be premature and inappropriate if the client no longer wishes to proceed with the surgery. While documenting the client's statement (Choice D) is important for documentation purposes, the immediate priority is to involve the provider in the decision-making process.

3. The nurse is preparing to administer a subcutaneous injection of insulin to a client with diabetes. What is the best site for the nurse to select for this injection?

Correct answer: D

Rationale: The correct answer is 'D: Abdomen.' The abdomen is the best site for insulin injections as it provides a larger area with consistent absorption rates due to the high vascularity of the area. The subcutaneous tissue in the abdomen allows for a more predictable and consistent absorption of insulin compared to other sites. Ventrogluteal and dorsogluteal sites are not commonly used for insulin injections due to the risk of hitting the sciatic nerve or causing tissue damage. The deltoid site is more commonly used for intramuscular injections rather than subcutaneous injections like insulin.

4. The healthcare provider prescribes 1,000 ml of Ringer's Lactate with 30 Units of Pitocin to run over 4 hours for a client who has just delivered a 10-pound infant by cesarean section. The tubing has been changed to a 20 gtt/ml administration set. The LPN/LVN plans to set the flow rate at how many gtt/min?

Correct answer: B

Rationale: To calculate the flow rate in drops per minute (gtt/min), the formula is Total volume (mL) ÷ Time (min) ÷ Drop factor (gtt/mL). In this case, 1000 mL ÷ 240 min ÷ 20 gtt/mL = 83 gtt/min. Therefore, setting the flow rate to 83 gtt/min ensures the correct administration of the IV fluids and medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the provided information.

5. A charge nurse is observing a newly licensed nurse prepare a sterile field. Which of the following actions should the charge nurse identify as contaminating the sterile field?

Correct answer: A

Rationale: The correct answer is A. Opening the sterile field on a wet surface contaminates it, rendering it unsafe for use. Moisture can carry microorganisms that can compromise the sterility of the field. Choice B is incorrect because turning away from the sterile field alone does not necessarily contaminate it unless the nurse touches non-sterile items. Choice C is incorrect because using a non-sterile glove to touch the sterile field directly introduces contaminants. Choice D is incorrect as touching the edge of the sterile drape with a hand may not necessarily contaminate the entire field, unlike opening it on a wet surface.
