Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?
- A. 11,000 units.
- B. 13,000 units.
- C. 15,000 units.
- D. 17,000 units.
Correct Answer: A
Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

When should discharge planning for a patient admitted to the neurological unit with a diagnosis of stroke begin?
- A. At the time of admission
- B. The day before the patient is to be discharged
- C. When outpatient therapy is no longer needed
- D. As soon as the patient's discharge destination is known
Correct Answer: A
Rationale: Discharge planning for a patient admitted to the neurological unit with a stroke diagnosis should begin at the time of admission. Initiating discharge planning early allows for a comprehensive assessment of the patient's needs, enables better coordination of care, and ensures a smooth transition from the hospital to the next level of care. Option B is incorrect because waiting until the day before discharge does not provide enough time for adequate planning. Option C is incorrect because waiting until outpatient therapy is no longer needed delays the planning process. Option D is incorrect because waiting until the discharge destination is known may result in rushed planning and inadequate preparation for the patient's needs.
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.
A nurse observes an assistive personnel (AP) reprimanding a client for not using the urinal properly. The AP tells the client that diapers will be used next time the urinal is used improperly. Which of the following torts is the AP committing?
- A. Assault
- B. Battery
- C. False imprisonment
- D. Invasion of privacy
Correct Answer: A
Rationale: The correct answer is A: Assault. Assault involves making threats or using actions that cause the client to fear harm. In this scenario, the AP's threat to use diapers next time the urinal is used improperly constitutes as assault. Choice B, Battery, involves intentional harmful or offensive touching without consent, which is not evident in the scenario. Choice C, False imprisonment, refers to restraining or restricting a client's freedom of movement, which is not occurring in this situation. Choice D, Invasion of privacy, involves violating a client's right to privacy, which is also not applicable here.
A nurse is precepting a newly licensed nurse who is preparing to help a client perform tracheostomy care. The nurse should intervene if the equipment the preceptee gathered included:
- A. Cotton balls
- B. Sterile gloves
- C. A suction catheter
- D. Tracheostomy tubes
Correct Answer: A
Rationale: The correct answer is A: Cotton balls. Cotton balls are not suitable for tracheostomy care due to the risk of lint and contamination. When performing tracheostomy care, sterile supplies such as sterile gloves, a suction catheter, and tracheostomy tubes are essential. Sterile gloves are needed to maintain asepsis, a suction catheter is necessary for airway clearance, and tracheostomy tubes are crucial for maintaining a patent airway. Cotton balls should be avoided to prevent introducing lint or fibers into the tracheostomy site, which can lead to infection or airway obstruction.
A client has acute renal failure. Which of the following assessments provides the most accurate measure of the client's fluid status?
- A. Daily weight
- B. Intake and output
- C. Urine specific gravity
- D. Peripheral edema
Correct Answer: A
Rationale: Daily weight is the most accurate measure of fluid status in a client with acute renal failure. Fluctuations in weight reflect changes in body fluid volume, including both fluid retention or loss. Intake and output, while important, may not always accurately reflect overall fluid status as it does not account for insensible losses. Urine specific gravity can provide information on urine concentration but does not offer a comprehensive assessment of overall fluid status. Peripheral edema, although a sign of fluid retention, is a more subjective assessment and may not always accurately reflect the client's fluid status like daily weight monitoring does.
