1. Why is atherosclerosis dangerous to arterial function?
- A. It diminishes central circulation
- B. It causes decreased blood pressure on artery walls
- C. It narrows the arterial lumen so a clot can easily block it
- D. It increases arterial elasticity
Correct answer: C
Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.
2. A healthcare professional is reviewing the laboratory findings of a client who has heart failure. Which of the following findings indicates that the client is experiencing fluid volume excess?
- A. BUN 8 mg/dL
- B. Hgb 15 g/dL
- C. Creatinine 0.8 mg/dL
- D. Sodium 140 mEq/L
Correct answer: A
Rationale: A BUN level of 8 mg/dL indicates fluid volume excess in a client with heart failure. BUN (Blood Urea Nitrogen) levels can be low in fluid overload due to hemodilution, a common occurrence in heart failure. High levels of BUN usually indicate dehydration or impaired renal function, which are not the case in fluid volume excess. Choices B, C, and D are within normal ranges and do not specifically indicate fluid volume excess.
3. The nurse notes that the fall might also cause a possible head injury. The patient will be observed for signs of increased intracranial pressure which include:
- A. Narrowing of the pulse pressure
- B. Vomiting
- C. Periorbital edema
- D. A positive Kernig's sign
Correct answer: C
Rationale: Periorbital edema is a sign of increased intracranial pressure. It is caused by fluid accumulation around the eyes due to compromised drainage. Narrowing of the pulse pressure is more indicative of shock than increased intracranial pressure. While vomiting can be a sign of increased intracranial pressure, it is not as specific as periorbital edema. A positive Kernig's sign is associated with meningitis, not increased intracranial pressure.
4. Bones continuously lose and gain minerals. This ongoing process is called?
- A. reorganization
- B. reorienting
- C. demineralizing
- D. remodeling
Correct answer: D
Rationale: The correct answer is D, 'remodeling.' Remodeling is the process by which bones continuously lose and gain minerals, maintaining bone strength and integrity over time. 'Reorganization' (choice A), 'reorienting' (choice B), and 'demineralizing' (choice C) do not accurately describe the process of bones continuously losing and gaining minerals.
5. What is the primary function of a written nursing care plan?
- A. Evaluates whether nursing care goals have been achieved
- B. Ensures the provision of quality nursing care
- C. Assists in selecting the appropriate nursing interventions
- D. Facilitates the creation of a nursing diagnosis
Correct answer: D
Rationale: A written nursing care plan fundamentally serves to facilitate the development of a nursing diagnosis. This procedure involves analyzing patient data and identifying health problems that nurses can address independently. This analysis then aids in determining the most appropriate nursing interventions for the identified health issues. Although evaluating the achievement of nursing care goals is an important aspect, it is not the primary function of a nursing care plan. Similarly, while delivering quality nursing care is crucial, it is a broader concept that includes many other facets beyond just the initial nursing diagnosis and interventions.
