When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?
- A. 2 liters/minute
- B. 4 liters/minute
- C. 6 liters/minute
- D. 8 liters/minute
Correct Answer: C
Rationale: The correct answer is 6 liters/minute. When a client requires oxygen therapy, the maximum flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Nasal cannula can effectively deliver oxygen up to 6 liters/minute. Flow rates exceeding 6 liters/minute may lead to drying of the nasal passages and discomfort for the client. Higher flow rates, like 8 liters/minute, should be administered using a mask to ensure sufficient oxygenation. Options A, B, and D are incorrect as they indicate flow rates that surpass the recommended maximum for nasal cannula delivery.

A nurse discusses staff empowerment with the nursing team. The nurse explains that staff empowerment has which function?
- A. Fosters the growth of others so that they are less dependent on the leader
- B. Means that the staff has the power to reprimand and punish any individual who is not meeting the standards of care delivery
- C. Indicates that the nurse leader will make decisions regarding the nursing unit and expects that the staff will comply with the changes
- D. Allows the staff to make every decision regarding employee scheduling
Correct Answer: A
Rationale: Staff empowerment fosters the growth of others and facilitates their development so that they are less dependent on their leader. This empowerment is about enhancing skills and autonomy, not about reprimanding or punishing others (Choice B). Empowerment involves shared decision-making and autonomy, not unilateral decision-making by the leader (Choice C). Moreover, staff empowerment does not mean that staff should make every decision regarding operational aspects like employee scheduling (Choice D). It is primarily focused on developing individuals' capabilities and fostering independence within the team.
Which of the following microorganisms are considered normal body flora?
- A. staphylococcus on the skin
- B. streptococcus in the nares
- C. candida albicans in the vagina
- D. pseudomonas in the blood
Correct Answer: A
Rationale: Staphylococcus is considered normal body flora as it is commonly found on the skin, being a part of the normal microbiota. While streptococcus in the nares can be part of the normal flora of the upper respiratory tract, it is not as common or as widespread as staphylococcus on the skin. Candida albicans in the vagina is not considered normal flora; it is a common opportunistic pathogen in the vagina. Pseudomonas in the blood is also not considered normal body flora; pseudomonas is not typically found in the blood as part of the normal microbiota.
A nurse is preparing to administer medications to a client via a nasogastric (NG) tube. Before administering the medication, the nurse must first take which action?
- A. Check the client's apical pulse
- B. Check when the last feeding was given
- C. Check the placement of the tube
- D. Check when the last medications were given
Correct Answer: C
Rationale: Before administering medications through an NG tube, the nurse must first check the placement of the tube to prevent aspiration. This is done by aspirating gastric contents and measuring the pH. Checking the client's apical pulse is unrelated to NG tube medication administration. Checking when the last feeding was given is important but not a priority before administering medications. Checking when the last medications were given is also not directly related to ensuring the safe administration of medications through an NG tube. Ensuring the correct placement of the tube is crucial to prevent complications such as pulmonary aspiration.
A nurse in charge of a long-term care facility who is working with a nursing assistant on the night shift prepares to take a break. To ensure client safety during the break, which actions should the nurse take? Select all that apply.
- A. Asking the nursing assistant to contact the health care provider during the nurse’s break if a client’s pain medication is not effective
- B. Informing the nursing assistant that she is leaving the nursing unit to get a cup of coffee from a vending machine in the lobby
- C. Asking the nursing assistant to administer a medication placed at the client's bedside if the client awakens
- D. Conducting client rounds before taking the break
Correct Answer: D
Rationale: The nurse is responsible for ensuring client safety at all times and must not leave the nursing unit for any reason during the shift. The nurse’s break should be taken in a designated area located on the nursing unit. Before taking the break, the nurse should check all clients to ensure that they are safe and comfortable and that their needs have been met. Conducting client rounds before taking the break is crucial to assess the clients' conditions and address any immediate needs, ensuring their safety. Asking the nursing assistant to contact the health care provider during the nurse’s break is not appropriate as the nurse should handle this responsibility. Leaving the nursing unit to get coffee is not recommended as the nurse should stay within the unit to respond promptly to any client needs. Asking the nursing assistant to administer medication or make clinical decisions is outside the scope of their practice and should not be delegated.
A nurse who works in a medical care unit is told that she must float to the intensive care unit because of a short-staffing problem on that unit. The nurse reports to the unit and is assigned to three clients. The nurse is angry with the assignment because she believes that the assignment is more difficult than the assignment delegated to other nurses on the unit and because the intensive care unit nurses are each assigned only one client. The nurse should most appropriately take which action?
- A. Refuse to do the assignment
- B. Tell the nurse manager to call the nursing supervisor
- C. Return to the medical care unit and discuss the assignment with the nurse manager on that unit
- D. Ask the nurse manager of the intensive care unit to discuss the assignment
Correct Answer: D
Rationale: In this scenario, the nurse feeling that the assignment is more difficult than what other nurses received should approach the nurse manager of the intensive care unit to discuss the assignment. By doing so, the nurse can seek clarification on the rationale for the assignment or confirm if it is genuinely more challenging. Refusing the assignment is not appropriate as it could impact patient care. Returning to the medical care unit would be considered client abandonment and does not directly address the conflict at hand. Instructing the nurse manager to involve the nursing supervisor is an aggressive approach that does not directly resolve the issue.
