1. How many drops per minute should a client weighing 182 pounds receive if a nurse mixes 50 mg of Nipride in 250 ml of D5W and plans to administer the solution at a rate of 5 mcg/kg/min? The drip factor is 60 gtt/ml.
- A. 31 gtt/min.
- B. 62 gtt/min.
- C. 93 gtt/min.
- D. 124 gtt/min.
Correct answer: D
Rationale: To determine the drops per minute for the client, first convert the client's weight from pounds to kilograms: 182/2.2 = 82.73 kg. Calculate the dosage by multiplying 5 mcg by the client's weight in kg: 5 mcg/kg/min × 82.73 kg = 413.65 mcg/min. Find the concentration of the solution in mcg/ml by dividing 250 ml by 50,000 mcg (50 mg): 250 ml/50,000 mcg = 200 mcg/ml. As the client needs 413.65 mcg/min and the solution is 200 mcg/ml, the client should receive 2.07 ml per minute. Finally, using the drip factor of 60 gtt/ml, multiply the ml per minute by the drip factor: 60 gtt/ml × 2.07 ml/min = 124.28 gtt/min, which rounds to 124 gtt/min. Therefore, the client should receive 124 drops per minute. Choice D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate calculation based on the client's weight, dosage, concentration of the solution, and drip factor.
2. Which instruction should be included in the discharge teaching plan for an adult client with hypernatremia?
- A. Monitor daily urine output volume
- B. Drink plenty of water whenever thirsty
- C. Use salt tablets for sodium content
- D. Review food labels for sodium content
Correct answer: D
Rationale: In hypernatremia, there is an excess of sodium in the blood. Reviewing food labels for sodium content is crucial as it helps the client identify and avoid high-sodium foods, which can contribute to elevated sodium levels. Monitoring urine output volume may be important for other conditions but is not directly related to managing hypernatremia. Drinking water whenever thirsty is generally good advice for staying hydrated but does not specifically address the issue of high sodium levels. Using salt tablets would worsen hypernatremia by further increasing sodium intake.
3. Urinary catheterization is prescribed for a postoperative female client who has been unable to void for 8 hours. The nurse inserts the catheter, but no urine is seen in the tubing. Which action will the nurse take next?
- A. Clamp the catheter and recheck it in 60 minutes.
- B. Pull the catheter back 3 inches and redirect it upward.
- C. Leave the catheter in place and reattempt with another catheter.
- D. Notify the healthcare provider of a possible obstruction.
Correct answer: C
Rationale: In this scenario, if no urine is seen in the tubing after inserting the catheter, it is likely that the catheter is in the vagina rather than the bladder. Leaving the first catheter in place will help locate the meatus more easily when attempting the second catheterization. This approach ensures correct placement of the catheter in the bladder and minimizes the risk of causing unnecessary discomfort or trauma to the patient.
4. A healthcare professional is working in an occupational health clinic when an employee walks in and states that he was struck by lightning while working in a truck. The client is alert but reports feeling faint. Which assessment will the healthcare professional perform first?
- A. Pulse characteristics
- B. Open airway
- C. Entrance and exit wounds
- D. Cervical spine injury
Correct answer: A
Rationale: When a person is struck by lightning, it can cause an electrical shock that may affect the heart rhythm. Therefore, assessing pulse characteristics is crucial as lightning can act as a natural defibrillator. Monitoring the pulse rate and regularity will help determine if there are any cardiac abnormalities that need immediate attention. Open airway, entrance and exit wounds, and cervical spine injury assessments are also important but assessing pulse characteristics takes precedence in this situation to address potential cardiac issues.
5. The client is being taught how to self-administer a subcutaneous injection. To ensure sterility of the procedure, which subject is most important for the instructor to include in the teaching plan?
- A. Hand washing before preparing the injection.
- B. Technique for drawing medication from a vial.
- C. Selection and rotation of injection sites.
- D. Proper disposal of injection equipment.
Correct answer: B
Rationale: To maintain the sterility of the procedure, it is crucial to teach the client the correct technique for drawing medication from a vial. This ensures that the medication remains sterile during preparation and administration. While hand washing, injection site selection, and equipment disposal are important aspects of injection safety, the key focus should be on maintaining the sterility of the medication itself to prevent infections and ensure the effectiveness of the treatment.
