Insulin forces which of the following electrolytes out of the plasma and into the cells?
- A. Calcium
- B. Magnesium
- C. Phosphorus
- D. Potassium
Correct Answer: D
Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.

Which patient is exercising their right to autonomy in the context of patient rights?
- A. An 86-year-old female who remains independent in terms of the activities of daily living.
- B. An unemancipated 16-year-old who chooses to not have an intravenous line.
- C. A 32-year-old who does not need the help of the nurse to bathe and groom themselves.
- D. A 99-year-old who wants CPR despite the fact that the nurse and doctor do not think that it would be successful.
Correct Answer: D
Rationale: The correct answer is D. A 99-year-old exercising their right to autonomy in the context of patient rights by choosing CPR. Autonomy in healthcare refers to the patient's right to make their own decisions about their care, even if healthcare providers may disagree. In this scenario, the 99-year-old patient is exercising autonomy by making an informed choice about their medical treatment, despite healthcare professionals having a different opinion. Choices A, B, and C do not directly demonstrate the exercise of autonomy in decision-making regarding medical treatment, making them incorrect.
What is the purpose of a healthcare audit?
- A. To increase paperwork
- B. To assess and improve quality of care
- C. To reduce patient satisfaction
- D. To limit healthcare services
Correct Answer: B
Rationale: The correct answer is B: 'To assess and improve quality of care.' Healthcare audits are conducted to evaluate the quality and efficiency of healthcare services provided. Choice A, 'To increase paperwork,' is incorrect as audits aim to streamline processes and reduce unnecessary paperwork. Choice C, 'To reduce patient satisfaction,' is incorrect as audits are meant to identify areas for improvement to enhance patient satisfaction. Choice D, 'To limit healthcare services,' is also incorrect as audits help in optimizing healthcare services rather than limiting them.
Which of the following healthcare providers can legally have access to all, or part, of a patient's medical record because they have a 'need to know'? Select one that does not apply.
- A. Student nurses caring for a particular patient
- B. Registered nurses when they are not caring for a particular patient
- C. The Vice President for nursing who is investigating a patient fall
- D. Licensed practical nurses caring for a particular patient
Correct Answer: B
Rationale: Student nurses, licensed practical nurses, the Vice President for nursing investigating a fall, and quality assurance nurses have a 'need to know' basis to access patient records. Registered nurses who are not directly involved in the care of a patient do not have a legitimate reason or 'need to know' to access that patient's medical records, making choice B the correct answer. The Vice President for nursing investigating a specific incident and licensed practical nurses directly involved in a patient's care have legitimate reasons to access the medical records, ensuring continuity and quality of care.
A nurse at a long-term care facility is planning a fall prevention program for the residents. Which of the following interventions should the nurse include?
- A. Apply vest restraints to residents who are confused
- B. Keep all four side rails up on beds at night
- C. Accompany residents over 85 years of age during ambulation
- D. Implement rounds every 2 hours during the day to offer toileting
Correct Answer: D
Rationale: The correct answer is to implement rounds every 2 hours during the day to offer toileting. This intervention helps prevent falls by addressing the common cause of unassisted mobility, which is the need to use the bathroom. Choice A is incorrect as restraints should not be the first choice for fall prevention due to the risk of injury and loss of independence. Choice B is incorrect because all side rails up can lead to entrapment and should only be used based on individualized assessments. Choice C may not be feasible for all residents over 85 years old and does not directly address the risk of falls.
A nurse manager is reviewing isolation guidelines with a newly licensed nurse. Which of the following statements by the newly licensed nurse indicates understanding of isolation guidelines?
- A. I will have a client who is on airborne precautions wear a mask when out of their room.
- B. I will wear an N95 respirator mask for a client who is on droplet precautions.
- C. I will place a client who has compromised immunity in a negative-pressure airflow room.
- D. I will instruct visitors to wear a mask when visiting a client who is on contact precautions.
Correct Answer: A
Rationale: The correct answer is A. Having a client on airborne precautions wear a mask when out of their room is appropriate to prevent the spread of infection. Choice B is incorrect because the healthcare provider, not the client, wears an N95 respirator mask for a client on droplet precautions. Choice C is incorrect because negative-pressure airflow rooms are used for clients with airborne infections, not compromised immunity. Choice D is incorrect because visitors, not clients, should wear a mask when visiting a client on contact precautions.
