The thymus gland role with the immune system is which of the following?
- A. Maturates B cells
- B. Maturates platelets
- C. Maturates red blood cells
- D. Maturates T cells
Correct Answer: D
Rationale: The correct answer is D: Maturates T cells. The thymus gland is crucial for the maturation of T cells, a type of white blood cell that plays a central role in the adaptive immune response. T cells mature in the thymus through a process of selection and education, where they learn to distinguish self from non-self antigens. This process is essential for the development of a functional immune system. Choices A, B, and C are incorrect because the thymus gland does not play a role in the maturation of B cells, platelets, or red blood cells, respectively.

A nurse is providing nursing care to a group of patients. Which actions are direct care interventions? (Select all that apply.)
- A. Ambulating a patient
- B. Inserting a feeding tube
- C. Performing resuscitation
- D. Documenting wound care
Correct Answer: A
Rationale: The correct answer is A: Ambulating a patient. Direct care interventions involve hands-on activities directly impacting patient outcomes. Ambulating a patient is a direct care intervention as it involves physically assisting the patient to move, promoting circulation, preventing complications, and improving overall well-being. Inserting a feeding tube (B) and performing resuscitation (C) are also direct care interventions as they involve immediate patient care actions. Documenting wound care (D) is not a direct care intervention as it involves recording information about a care activity rather than physically performing the care itself.
A nurse is using the problem-oriented approach to data collection. Which action will the nurse take first?
- A. Complete the questions in chronological order.
- B. Focus on the patient’s presenting situation.
- C. Make accurate interpretations of the data.
- D. Conduct an observational overview.
Correct Answer: B
Rationale: The correct answer is B because the problem-oriented approach involves focusing on the patient's presenting situation to identify the main issues and prioritize data collection. This step helps the nurse understand the immediate concerns and sets the direction for further assessment and interventions.
Choice A is incorrect because completing questions in chronological order may not address the most urgent issues. Choice C is incorrect as accurate interpretations come after collecting relevant data. Choice D is incorrect as conducting an observational overview is part of the assessment process but not the first step in the problem-oriented approach.

- A. Complete the questions in chronological order.
- B. Focus on the patient’s presenting situation.
- C. Make accurate interpretations of the data.
- D. Conduct an observational overview.
Correct Answer: B
Rationale: The correct answer is B: Focus on the patient's presenting situation. This is the first step in the problem-oriented approach as it helps the nurse understand the immediate issues and prioritize data collection. By focusing on the presenting situation, the nurse can gather relevant information efficiently.
A: Completing questions in chronological order may not address the current problem effectively.
C: Making accurate interpretations of the data comes after data collection, not as the first step.
D: Conducting an observational overview is important but typically follows focusing on the presenting situation to guide what observations are necessary.
Which of the ff must the nurse consider when administering IV fluids to clients with hypertension?
- A. The nurse checks the clients BP every hour
- B. The nurse checks the site and progress of the infusion every hour
- C. The nurse checks the progress of the infusion once a day
- D. The nurse checks the client’s pulse rate every hour
Correct Answer: B
Rationale: The correct answer is B because monitoring the site and progress of the infusion every hour is crucial to prevent complications like infiltration or infection in clients with hypertension. Choice A is incorrect as checking BP every hour is excessive. Choice C is incorrect as daily monitoring may not detect issues promptly. Choice D is incorrect as pulse rate monitoring is not directly related to IV fluid administration in this context. Monitoring the site and progress hourly ensures timely intervention if any issues arise.
Mr. Mariano was on his way home from a party. Apparently, he got drunk and lost his balance and suffered a vehicular accident. Upon arrival at the hospital, the nurse noticed that his only injury is an open fracture of the left humerus. Which assessment finding by the nurse is critical?
- A. status of client’s tetanus immunization
- B. current blood alcohol level
- C. support systems available at home to assist with care
- D. last time client voided
Correct Answer: A
Rationale: The correct answer is A: status of client’s tetanus immunization. It is critical because an open fracture poses a risk of infection, and tetanus prophylaxis is necessary to prevent tetanus infection. Tetanus is caused by a bacterium commonly found in soil and can enter the body through open wounds. Assessing the client's tetanus immunization status helps determine the need for a tetanus booster to prevent potential complications.
Incorrect choices:
B: Current blood alcohol level - While relevant to the situation, the priority in this case is preventing infection from the open fracture.
C: Support systems available at home to assist with care - Important for discharge planning but not the immediate priority.
D: Last time client voided - Not critical in this scenario compared to preventing infection from the open fracture.
