1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

2. 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.

3. A client who is lactating is being taught about taking medications by a nurse. Which of the following actions should the nurse recommend to minimize the entry of medication into breast milk?

• A. Drink 8 oz of water with each dose of medication.
• B. Use medications that have a short half-life.
• C. Take each dose right after breastfeeding.
• D. Pump breast milk and discard it prior to feeding the newborn.

Correct answer: C

Rationale: Taking medications immediately after breastfeeding helps minimize the amount of medication that enters breast milk. By doing so, there is a longer interval between the medication intake and the next breastfeeding session, reducing the concentration of the medication in breast milk. Options A and B are incorrect as drinking water with medication or using medications with a short half-life do not directly minimize the entry of medication into breast milk. Option D is unnecessary and wasteful as pumping and discarding breast milk before feeding is not as effective as timing medication intake with breastfeeding to reduce medication transfer into breast milk.

4. At the time of the first dressing change, the client refuses to look at her mastectomy incision. The LPN tells the client that the incision is healing well, but the client refuses to talk about it. What would be an appropriate response to this client's silence?

• A. It is normal to feel angry and depressed, but the sooner you deal with this surgery, the better you will feel.
• B. Looking at your incision can be frightening, but facing this fear is a necessary part of your recovery.
• C. It is OK if you don't want to talk about your surgery. I will be available when you are ready.
• D. I will ask a woman who has had a mastectomy to come by and share her experiences with you.

Correct answer: C

Rationale: In this situation, it's essential to acknowledge and respect the client's feelings and choices. Choice C is the most appropriate response as it validates the client's decision not to discuss the surgery while offering support and understanding. Giving the client space and letting them know you will be available when they are ready shows empathy and fosters trust. Choices A and B do not respect the client's autonomy and may come across as dismissive or pressuring. Choice D assumes the client needs advice from someone who has had a similar experience without considering the client's current emotional state and preferences.

5. When working with a client who does not speak the same language as the nurse and an interpreter is present, which of the following actions should the nurse take?

• A. Talk directly to the client, instead of the interpreter, when speaking.
• B. Speak loudly to the interpreter.
• C. Use gestures to communicate with the client.
• D. Avoid using an interpreter and rely on family members.

Correct answer: A

Rationale: When caring for a client who speaks a different language, it is essential to communicate through an interpreter. Talking directly to the client, rather than the interpreter, ensures clear and respectful interaction. Speaking loudly to the interpreter (choice B) is not necessary and may be perceived as disrespectful. Using gestures (choice C) alone may lead to misunderstandings or misinterpretations. Avoiding the use of an interpreter and relying solely on family members (choice D) can compromise the accuracy and confidentiality of the communication.
