Which part of the brain controls breathing?
- A. Medulla
- B. Cerebrum
- C. Cerebellum
- D. Thalamus
Correct Answer: A
Rationale: The correct answer is A: Medulla. The medulla is located in the brainstem and plays a crucial role in controlling involuntary functions like breathing. It contains the respiratory center, which regulates the rate and depth of breathing. The medulla sends signals to the diaphragm and intercostal muscles to control breathing. The cerebrum (B) is responsible for higher brain functions, not breathing control. The cerebellum (C) coordinates movement and balance, not breathing. The thalamus (D) relays sensory information to the cerebral cortex, not involved in breathing regulation.

Which patient is most at risk for fluid volume overload?
- A. The 40-year-old with meningitis
- B. The 60-year-old with psoriasis
- C. The 35-year-old with kidney failure
- D. The 2-year-old with influenza
Correct Answer: C
Rationale: The correct answer is C, the 35-year-old with kidney failure. Patients with kidney failure are at high risk for fluid volume overload due to the kidneys' inability to properly regulate fluid balance. This can lead to accumulation of excess fluids in the body, causing edema, hypertension, and heart failure. In contrast, choices A, B, and D are not at as high risk for fluid volume overload as patients with kidney failure, as their conditions do not directly impact fluid regulation in the body.
A patient is unable to control his bowels ff. a subarachnoid hemorrhage. Which intervention by the nurse can help reduce episodes of bowel incontinence?
- A. Ask the patient frequently if he has to have a bowel movement
- B. Place incontinence pads on the patient’s bed and chair
- C. Toilet the patient according to his pre-illness schedule, whether or not he feels the urge
- D. Take care not to embarrass the patient when incontinent episode occur
Correct Answer: C
Rationale: The correct answer is C: Toilet the patient according to his pre-illness schedule, whether or not he feels the urge. This intervention helps establish a routine for bowel movements, which can aid in reducing episodes of bowel incontinence. By following the patient's pre-illness schedule, the nurse can help regulate bowel movements and prevent accidents.
A: Asking the patient frequently if he has to have a bowel movement may not address the underlying issue of bowel incontinence.
B: Placing incontinence pads on the patient's bed and chair is a reactive measure and does not address the root cause of the issue.
D: Taking care not to embarrass the patient when incontinent episodes occur is important for emotional support but does not directly address reducing episodes of bowel incontinence.
A clinical nurse specialist (CNS) is orienting a new graduate registered nurse to an oncology unit where blood product transfusions are frequently administered. In discussing ABO compatibility, the CNS presents several hypothetical scenarios. A well-informed new graduate would know the greatest likelihood of an acute hemolytic reaction would occur when giving:
- A. A-positive blood to an A-negative client
- B. O-positive blood to an A-positive client
- C. O-negative blood to an O-positive client
- D. B-positive blood to an AB-positive client
Correct Answer: A
Rationale: The correct answer is A: A-positive blood to an A-negative client. This is because in ABO blood typing, individuals with blood type A have anti-B antibodies in their plasma. Therefore, if A-positive blood (which contains the A antigen) is given to an A-negative client (who has anti-A antibodies), there is a high risk of an acute hemolytic reaction due to the antibodies attacking the transfused blood cells.
Choices B, C, and D are incorrect because they do not involve a mismatch of ABO blood types that would lead to a significant risk of acute hemolytic reaction. In choice B, O-positive blood can be safely transfused to an A-positive client as O blood is considered the universal donor. In choice C, O-negative blood can be safely given to an O-positive client as O-negative blood is compatible with all blood types. In choice D, B-positive blood can be safely administered to an AB-positive client as the AB blood type can receive both
As part of primary cancer prevention program, an oncology nurse answers questions from the public at health fair. When someone asks about the laryngeal cancer, the nurse should explain that:
- A. Laryngeal cancer is one of the most preventable types of cancer
- B. Inhaling polluted air isn’t a risk factor for laryngeal cancer
- C. Laryngeal cancer occurs primarily in women
- D. Adenocarcinoma accounts for most cases of laryngeal cancer
Correct Answer: A
Rationale: The correct answer is A: Laryngeal cancer is one of the most preventable types of cancer. This is because the primary risk factors for laryngeal cancer are largely related to lifestyle choices such as smoking, excessive alcohol consumption, and exposure to certain occupational hazards. By avoiding these risk factors, individuals can significantly reduce their chances of developing laryngeal cancer.
Choices B, C, and D are incorrect:
B: Inhaling polluted air isn’t a risk factor for laryngeal cancer - This is incorrect as exposure to polluted air can contribute to the development of laryngeal cancer.
C: Laryngeal cancer occurs primarily in women - This is incorrect as laryngeal cancer occurs more frequently in men than in women.
D: Adenocarcinoma accounts for most cases of laryngeal cancer - This is incorrect as squamous cell carcinoma is the most common type of laryngeal cancer, not adenocarcin
What is an example of a nurse modifying the care plan during the evaluation phase?
- A. Adding a new intervention to address an unmet goal.
- B. Performing routine monitoring of the client’s condition.
- C. Administering medication as prescribed by the physician.
- D. Completing discharge paperwork for the client.
Correct Answer: A
Rationale: The correct answer is A because modifying the care plan during the evaluation phase involves making changes based on the client's response to interventions. By adding a new intervention to address an unmet goal, the nurse demonstrates critical thinking and adaptability in response to the client's needs. This action shows that the nurse is actively assessing and revising the care plan to ensure it is effective in meeting the client's goals.
Choice B is incorrect because routine monitoring is part of the assessment and implementation phases, not specifically related to modifying the care plan during evaluation. Choice C is incorrect as administering medication is part of the implementation phase and does not necessarily involve modifying the care plan. Choice D is also incorrect as completing discharge paperwork is typically part of the discharge planning phase, not the evaluation phase where modifications to the care plan are made based on client outcomes.
