1. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?
- A. Blood glucose of 350 mg/dL
- B. Serum bicarbonate of 18 mEq/L
- C. Arterial pH of 7.20
- D. Serum potassium of 5.5 mEq/L
Correct answer: C
Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.
2. 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.
3. A healthcare professional is caring for a client who has a prescription for a vest restraint. Which of the following actions should the healthcare professional take?
- A. Tie the restraint with a quick-release knot.
- B. Use a slipknot to secure the restraint.
- C. Ensure the restraint is tightly secured.
- D. Attach the restraint to the bed frame.
Correct answer: A
Rationale: The correct action for the healthcare professional to take when applying a vest restraint is to tie it with a quick-release knot. A quick-release knot allows for easy and rapid removal in case of an emergency, ensuring the safety of the client. Using a slipknot (Choice B) is not recommended as it may not provide quick release in emergencies. Ensuring the restraint is tightly secured (Choice C) can be dangerous as it can restrict circulation or cause discomfort. Attaching the restraint to the bed frame (Choice D) is inappropriate and can lead to potential harm or injury to the client.
4. The nurse is caring for a 17-month-old child with acetaminophen poisoning. Which laboratory reports should the nurse review first?
- A. Prothrombin time (PT) and partial thromboplastin time (PTT)
- B. Red blood cell and white blood cell counts
- C. Blood urea nitrogen and creatinine levels
- D. Liver enzymes (AST and ALT)
Correct answer: D
Rationale: In acetaminophen poisoning, liver damage is a significant concern due to the drug's metabolism in the liver. Monitoring liver enzymes such as AST and ALT is crucial as they indicate liver function and damage. Prothrombin time (PT) and partial thromboplastin time (PTT) (Choice A) are coagulation studies and are not the priority in acetaminophen poisoning. Red blood cell and white blood cell counts (Choice B) are not directly related to acetaminophen poisoning. Blood urea nitrogen and creatinine levels (Choice C) assess kidney function, but liver enzymes are more specific for evaluating liver damage in acetaminophen poisoning.
5. The client with gastroesophageal reflux disease (GERD) is receiving dietary modification education from the nurse. Which statement by the client indicates a need for further teaching?
- A. I will avoid eating large meals before bedtime.
- B. I will limit coffee consumption to the morning hours.
- C. I will elevate the head of my bed while sleeping.
- D. I will avoid spicy and acidic foods.
Correct answer: B
Rationale: The correct answer is B. Clients with GERD should avoid coffee as it can relax the lower esophageal sphincter and exacerbate symptoms. Limiting coffee consumption to the morning hours may not be sufficient, as coffee can still contribute to GERD symptoms throughout the day. Choices A, C, and D are all appropriate strategies for managing GERD symptoms. Avoiding large meals before bedtime, elevating the head of the bed while sleeping, and steering clear of spicy and acidic foods are all recommended practices to help alleviate GERD symptoms. Therefore, the client's statement in option B indicates a need for further teaching to completely address dietary modifications for managing GERD.
