Nursing Elites

1. A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 0.5 mL
• B. 1 mL
• C. 1.5 mL
• D. 2 mL

Correct answer: A

Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg ÷ 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.

2. A nurse at a screening clinic is assessing a client who reports a history of a heart murmur related to aortic valve stenosis. At which of the following anatomical areas should the nurse place the stethoscope to auscultate the aortic valve?

• A. Second intercostal space to the right of the sternum
• B. Fifth intercostal space at the midclavicular line
• C. Left sternal border
• D. Fifth intercostal space at the anterior axillary line

Correct answer: B

Rationale: The correct placement to auscultate the aortic valve is at the second intercostal space to the right of the sternum, which coincides with the aortic area. The choice stating 'Fifth intercostal space at the midclavicular line' is the correct answer for auscultating the aortic valve. Placing the stethoscope at the left sternal border would be more suitable for listening to the tricuspid valve. The fifth intercostal space at the anterior axillary line is the recommended area for auscultating the mitral valve. Therefore, choice B is the correct answer for assessing the aortic valve in a client with a history of a heart murmur related to aortic valve stenosis.

3. When using an open irrigation technique to irrigate a client's indwelling urinary catheter, which of the following actions should the nurse take?

• A. Place the client in a side-lying position
• B. Instill 15 mL of irrigation fluid into the catheter with each flush
• C. Subtract the amount of irrigant used from the client's urine output
• D. Perform the irrigation using a 20 mL syringe

Correct answer: C

Rationale: The correct action for the nurse to take when using an open irrigation technique on a client with an indwelling urinary catheter is to subtract the amount of irrigant used from the client's urine output. This calculation helps ensure an accurate measurement of the client's actual urine output by accounting for the irrigation fluid introduced into the catheter. Placing the client in a side-lying position (Choice A) is not directly related to the irrigation procedure. Instilling a specific volume of irrigation fluid (Choice B) may vary depending on the client's condition and the healthcare provider's order. Using a 20 mL syringe for irrigation (Choice D) is a matter of equipment choice and does not directly impact the calculation of urine output in this context.

4. A client with diabetes mellitus is admitted with a blood glucose level of 600 mg/dL. What is the priority nursing action for the LPN/LVN?

• A. Administer insulin as prescribed.
• B. Administer oral hypoglycemic agents.
• C. Monitor blood glucose levels frequently.
• D. Provide a high-calorie diet.

Correct answer: A

Rationale: The correct answer is to administer insulin as prescribed. When a client with diabetes mellitus presents with a critically high blood glucose level like 600 mg/dL, the priority action is to lower the blood glucose level promptly to prevent complications. Insulin is the appropriate medication to rapidly reduce high blood glucose levels. Administering oral hypoglycemic agents may not act quickly enough in this critical situation. While monitoring blood glucose levels frequently is important, immediate intervention to lower the high blood glucose level takes precedence. Providing a high-calorie diet is contraindicated in this scenario as it would further elevate the blood glucose level.

5. A client with a history of asthma is experiencing shortness of breath. What is the most appropriate action for the LPN/LVN to take first?

• A. Administer a bronchodilator as prescribed.
• B. Encourage the client to practice deep breathing exercises.
• C. Position the client in high Fowler's position.
• D. Obtain a peak flow reading.

Correct answer: A

Rationale: Administering a bronchodilator as prescribed is the most appropriate initial action for managing asthma-related shortness of breath. Bronchodilators help to open up the airways quickly, providing relief for the client. Encouraging deep breathing exercises may be beneficial in some situations but should not be the first action for acute shortness of breath in asthma. Positioning the client in high Fowler's position can also help improve breathing, but administering the bronchodilator takes precedence. Obtaining a peak flow reading is important in asthma management, but it is not the initial action needed to address acute shortness of breath.
