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.

During an assessment, a healthcare professional observes significant tenting of the skin over an older adult client's forearm. What factor should the healthcare professional primarily consider as a cause for this finding?
- A. Thin, parchment-like skin
- B. Loss of adipose tissue
- C. Dehydration
- D. Diminished skin elasticity
Correct Answer: C
Rationale: Dehydration is the primary factor to consider in this scenario. Dehydration leads to decreased skin turgor and tenting, where the skin does not return to its normal position when pinched. While thin, parchment-like skin, loss of adipose tissue, and diminished skin elasticity can contribute to skin changes, they are not the primary cause of the significant tenting observed.
A nurse is caring for a group of clients. Which of the following actions should the nurse take to prevent the spread of infection?
- A. Carry a client's soiled linens out of the room in a mesh linen bag
- B. Place a client who has tuberculosis in a room with negative-pressure airflow
- C. Provide disposable plates and utensils for a client who is HIV-positive
- D. Dispose of a client's blood-saturated dressing in a biohazard bag
Correct Answer: B
Rationale: A client who has tuberculosis requires airborne precautions, including placing the client in a room with negative-pressure airflow to reduce the risk of infection transmission. Choices A, C, and D are incorrect. Carrying soiled linens in a mesh bag, providing disposable plates and utensils for an HIV-positive client, and disposing of blood-saturated dressing in a biohazard bag do not specifically address preventing the spread of tuberculosis, which requires airborne precautions.
A client with hypertension is prescribed a low-sodium diet. Which food should the LPN/LVN recommend the client avoid?
- A. Fresh fruits
- B. Grilled chicken
- C. Whole grain bread
- D. Canned soup
Correct Answer: D
Rationale: The correct answer is D, canned soup. Canned soup is often high in sodium, which contradicts the low-sodium diet prescribed for hypertension. Fresh fruits (A) are generally low in sodium and are a healthy choice. Grilled chicken (B) is a lean protein option that is suitable for a low-sodium diet. Whole grain bread (C) is also a good choice as it is not typically high in sodium. Therefore, the LPN/LVN should recommend avoiding canned soup to adhere to the low-sodium dietary restrictions.
A client with diabetes mellitus and a new prescription for insulin is being discharged. Which of the following actions should the nurse plan to complete first?
- A. Provide the client with printed information on insulin self-administration.
- B. Obtain printed information on insulin self-administration.
- C. Make a copy of the medication reconciliation form for the client.
- D. Determine whether the client can afford the insulin administration supplies.
Correct Answer: B
Rationale: Obtaining printed information on insulin self-administration should be the nurse's first priority. This action ensures that the client has the necessary knowledge to safely self-administer insulin at home. Providing the client with printed information (Choice A) is essential to empower the client with the required knowledge before considering additional resources. Making a copy of the medication reconciliation form for the client (Choice C) is important for documentation purposes but not as urgent as ensuring the client's understanding of insulin administration. Determining the client's ability to afford insulin administration supplies (Choice D) is crucial but should follow after ensuring the client is equipped with the necessary information for safe self-administration.
What is the most important aspect for the nurse to include in the discharge plan for a client performing his own dressing changes at home following abdominal surgery?
- A. Demonstration of appropriate hand hygiene
- B. Explanation of wound care technique
- C. Review of signs and symptoms of infection
- D. Instructions for when to contact the healthcare provider
Correct Answer: A
Rationale: The most critical aspect for the nurse to include in the discharge plan for a client performing his own dressing changes at home following abdominal surgery is the demonstration of appropriate hand hygiene. Proper hand hygiene is essential to prevent the introduction of infection during dressing changes. While wound care technique, signs and symptoms of infection, and instructions for contacting the healthcare provider are all important components of the discharge plan, ensuring the client understands and practices proper hand hygiene is paramount to minimize the risk of infection. This choice takes precedence as it directly addresses infection prevention during the dressing changes, which is crucial for successful post-operative recovery.
