Nursing Elites

1. A nurse is preparing an infusion for a client who was hospitalized with deep-vein thrombosis. The orders read: 25,000 units of heparin in 250 mL of 0.9% sodium chloride to infuse at 800 units/hr. At what rate should the nurse set the infusion pump?

• A. 8 mL/hr
• B. 10 mL/hr
• C. 12 mL/hr
• D. 15 mL/hr

Correct answer: A

Rationale: To calculate the infusion rate, use the formula: (Desired units/hr / Total units) × Volume. In this case, it would be (800 units/hr / 25,000 units) × 250 mL = 8 mL/hr. Therefore, the nurse should set the infusion pump at 8 mL/hr. Choice B, 10 mL/hr, is incorrect because it does not match the calculated rate. Choices C and D, 12 mL/hr and 15 mL/hr respectively, are also incorrect as they do not align with the correct calculation based on the provided data.

2. The healthcare provider retrieves hydromorphone 4mg/mL from the Pyxis MedStation, an automated dispensing system, for a client who is receiving hydromorphone 3 mg IM every 6 hours PRN for severe pain. How many mL should the healthcare provider administer to the client?

• A. 0.75 mL
• B. 1 mL
• C. 0.8 mL
• D. 1.2 mL

Correct answer: C

Rationale: The correct dosage calculation is to divide the prescribed dose by the concentration of the medication to determine the volume needed. In this case, 3 mg (prescribed dose) divided by 4 mg/mL (concentration) equals 0.75 mL. Therefore, the healthcare provider should administer 0.75 mL of hydromorphone to the client. Choices A, B, and D are incorrect because they do not accurately calculate the required volume based on the prescription and concentration provided.

3. A client with cardiovascular disease is being taught by a nurse how to reduce sodium and cholesterol intake. The nurse understands that the most significant factor in planning dietary changes for this client is:

• A. Client’s financial resources
• B. Involvement of the client in planning the change
• C. Availability of low-sodium foods
• D. Frequency of dietary counseling sessions

Correct answer: B

Rationale: The most significant factor in planning dietary changes for a client with cardiovascular disease is the involvement of the client in planning the change. By involving the client in the planning process, the nurse ensures that the client takes ownership of their health and is more likely to adhere to and succeed in modifying dietary habits. This empowerment and engagement enhance the client's motivation and commitment to making sustainable changes. Financial resources, availability of low-sodium foods, and frequency of dietary counseling sessions are important considerations but are not as crucial as the client's active involvement in the planning process.

4. A client who is postoperative following abdominal surgery has an eviscerated wound. What should the nurse do first?

• A. Cover the incision with a moist sterile dressing.
• B. Notify the surgeon immediately.
• C. Assess the client's vital signs.
• D. Place the client in a supine position with knees bent.

Correct answer: A

Rationale: The initial action the nurse should take after discovering a client's eviscerated wound is to cover the incision with a moist sterile dressing. This step is crucial to protect the exposed tissue, prevent infection, and create a conducive environment for healing. While notifying the surgeon is important, addressing the wound immediately takes precedence. Assessing vital signs is essential but should follow the immediate intervention of covering the wound. Placing the client in a supine position with knees bent is not the priority in managing an eviscerated wound; the first step is to cover the wound to protect the exposed tissue.

5. 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?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Increased serum hemoglobin levels
• D. Decreased serum potassium levels

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.
