Nursing Elites

1. A client is to receive 10 mEq of KCl diluted in 250 ml of normal saline over 4 hours. At what rate should the nurse set the client's intravenous infusion pump?

• A. 13 ml/hour.
• B. 63 ml/hour.
• C. 80 ml/hour.
• D. 125 ml/hour.

Correct answer: B

Rationale: The correct calculation involves dividing the total volume by the total time. In this case, 250 ml/4 hours = 63 ml/hour. The dose of KCl is not used in the calculation as the focus is on the rate of infusion over the specified time period. Choice A (13 ml/hour) is incorrect as it does not result from the correct calculation. Choice C (80 ml/hour) and Choice D (125 ml/hour) are also incorrect calculations and do not match the correct rate of infusion required.

2. The nurse is providing discharge teaching to a client with a new diagnosis of osteoporosis. Which instruction should the nurse include?

• A. Increase dietary intake of calcium-rich foods.
• B. Avoid activities that increase the risk of falls.
• C. Avoid prolonged exposure to sunlight.
• D. Increase intake of vitamin D supplements.

Correct answer: B

Rationale: Avoiding activities that increase the risk of falls (B) is the most crucial instruction for a client with osteoporosis to prevent fractures. Osteoporosis weakens bones, making them more susceptible to fractures from falls. While increasing calcium intake (A) is important for bone health, avoiding falls takes precedence to prevent immediate harm. Avoiding prolonged exposure to sunlight (C) is not directly related to osteoporosis management. Increasing vitamin D supplements (D) is beneficial for bone health, but fall prevention is more critical in this scenario.

3. A client with a history of diabetes mellitus is admitted with a blood glucose level of 600 mg/dL. What type of insulin should the nurse prepare to administer to this client?

• A. Regular insulin
• B. NPH insulin
• C. Lispro insulin
• D. Glargine insulin

Correct answer: A

Rationale: In a client with a blood glucose level of 600 mg/dL, which indicates severe hyperglycemia or diabetic ketoacidosis, the nurse should prepare to administer regular insulin (A). Regular insulin has a rapid onset of action and is the preferred choice for immediate correction of high blood glucose levels. NPH insulin (B), lispro insulin (C), and glargine insulin (D) are not suitable for the rapid correction of severe hyperglycemia.

4. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which assessment finding should the nurse anticipate?

• A. Oliguria.
• B. Kussmaul respirations.
• C. Fruity odor on the breath.
• D. Blood glucose level of 250 mg/dL.

Correct answer: B

Rationale: Kussmaul respirations (B) are a deep and labored breathing pattern associated with diabetic ketoacidosis (DKA) and are expected in this condition. While oliguria (A), fruity odor on the breath (C), and elevated blood glucose level (D) are also signs of DKA, Kussmaul respirations are more specific and critical to the condition, indicating severe metabolic acidosis.

5. Why is it most important to start intravenous infusions in the upper extremities rather than the lower extremities of adults?

• A. Superficial veins are more easily found in the feet and ankles.
• B. A decreased flow rate could lead to thrombosis formation.
• C. It is more challenging to move a cannulated extremity when using the leg or foot.
• D. Veins in the feet and ankles are located deep, making the procedure more painful.

Correct answer: B

Rationale: The most critical reason for initiating intravenous infusions in the upper extremities of adults is to reduce the risk of thrombosis (B). Venous return is typically better in the upper extremities, decreasing the likelihood of thrombus formation, which could be life-threatening if dislodged. Although superficial veins are easily found in the feet and ankles (A), this is not the primary reason for choosing the upper extremities. Handling a leg or foot with an IV (C) is not significantly more challenging than handling an arm or hand. The depth of veins in the feet and ankles (D) does not primarily determine the site for IV placement.
