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. The nurse is providing discharge teaching to a client who has a new prescription for digoxin (Lanoxin). Which statement by the client indicates a need for further teaching?

• A. I will take my pulse before taking the medication.
• B. I will take the medication at the same time every day.
• C. I should avoid taking antacids at the same time as this medication.
• D. I should eat foods high in potassium while taking this medication.

Correct answer: D

Rationale: The correct answer is D. Clients taking digoxin should avoid eating foods high in potassium, as this can affect the medication's efficacy. Choices A, B, and C are correct statements regarding digoxin administration and precautions, indicating the client's understanding of the medication and its management.

3. A client with chronic kidney disease is being assessed. Which of the following laboratory values would be most concerning?

• A. Serum creatinine of 3.0 mg/dL
• B. Serum potassium of 6.5 mEq/L
• C. Blood urea nitrogen (BUN) of 45 mg/dL
• D. Hemoglobin of 10 g/dL

Correct answer: B

Rationale: In a client with chronic kidney disease, elevated serum potassium levels (hyperkalemia) are the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias. Monitoring and managing serum potassium levels are crucial in patients with kidney disease to prevent severe complications. While elevated creatinine (Choice A) and BUN (Choice C) are indicative of impaired kidney function, hyperkalemia poses a more immediate threat to the client's health. Hemoglobin levels (Choice D) can be affected by chronic kidney disease but are not as acutely dangerous as severe hyperkalemia.

4. The healthcare provider is observing the way a patient walks. Which aspect is the healthcare provider assessing?

• A. Activity tolerance
• B. Body alignment
• C. Range of motion
• D. Gait

Correct answer: D

Rationale: When assessing the way a patient walks, the healthcare provider is evaluating the gait, which refers to a particular manner or style of walking. Body alignment pertains to the positioning of body parts in relation to one another, range of motion refers to the extent of movement of a joint, and activity tolerance relates to the ability to endure physical activities. In this scenario, observing the patient's walking pattern specifically focuses on gait assessment.

5. When obtaining a urine specimen for a culture and sensitivity from an indwelling catheter, the nurse should:

• A. Cleanse the entry port prior to withdrawing urine.
• B. Use a sterile syringe to collect urine from the collection bag.
• C. Obtain the specimen from the drainage tubing.
• D. Replace the catheter before obtaining the specimen.

Correct answer: A

Rationale: The correct procedure when obtaining a urine specimen from an indwelling catheter for culture and sensitivity is to cleanse the entry port before withdrawing urine. This step helps reduce the risk of contamination and ensures the accuracy of the results. Option B is incorrect because using a sterile syringe to collect urine from the collection bag is not the recommended method for obtaining a catheter specimen. Option C is incorrect as obtaining the specimen from the drainage tubing is not the appropriate technique for collecting a urine sample from an indwelling catheter. Option D is incorrect because replacing the catheter before obtaining the specimen is not necessary and may introduce unnecessary complications.
