Select the type of skeletal fracture that is correctly paired with its description.
- A. A complete fracture: The fractured bone penetrates through the skin to the skin surface.
- B. A pathological fracture: A fracture that results from some physical trauma.
- C. A greenstick fracture: This bends but does not fracture the bone.
- D. An avulsion fracture: A fracture that pulls a part of the bone from the tendon or ligament
Correct Answer: D
Rationale: The correct answer is D. An avulsion fracture occurs when a part of the bone is pulled away by a tendon or ligament. Choice A is incorrect because it describes an open fracture where the bone penetrates the skin. Choice B is incorrect as a pathological fracture results from an underlying disease weakening the bone, not physical trauma. Choice C is incorrect as a greenstick fracture involves the bone bending but not completely breaking.

A nurse is reviewing laboratory results and notes that a client's serum sodium level is 150 mEq/L. The nurse reports the serum sodium level to the physician, and the physician prescribes dietary instructions based on the sodium level. Which food item should the nurse instruct the client to avoid?
- A. Peas
- B. Cauliflower
- C. Low-fat yogurt
- D. Processed oat cereals
Correct Answer: D
Rationale: The correct answer is processed oat cereals. Processed oat cereals are often high in sodium content, which should be avoided in cases of hypernatremia. Peas, cauliflower, and low-fat yogurt are generally low in sodium and are not typically contraindicated in hypernatremia. Therefore, choices A, B, and C are incorrect.
A nurse reviews a client's laboratory report and notes that the client's serum phosphorus level is 2.0 mg/dL. Which condition most likely caused this serum phosphorus level?
- A. Alcoholism
- B. Renal insufficiency
- C. Hypoparathyroidism
- D. Tumor lysis syndrome
Correct Answer: A
Rationale: The correct answer is A: Alcoholism. Alcoholism can lead to hypophosphatemia due to poor dietary intake and other factors. Excessive alcohol consumption can result in malnutrition, particularly a deficiency in phosphorus. Choices B, C, and D are unlikely to cause low serum phosphorus levels. Renal insufficiency is more likely to cause hyperphosphatemia, hypoparathyroidism is associated with hypocalcemia rather than hypophosphatemia, and tumor lysis syndrome typically presents with hyperphosphatemia due to the release of intracellular phosphate.
What is a major benefit of electronic health records (EHRs)?
- A. Increased paperwork
- B. Better coordination of care
- C. Higher risk of data breaches
- D. More manual data entry
Correct Answer: B
Rationale: The major benefit of electronic health records (EHRs) is better coordination of care. EHRs allow healthcare providers to access and share patient information more efficiently, leading to improved coordination and continuity of care. Choice A, increased paperwork, is incorrect as EHRs aim to reduce paperwork by digitizing and centralizing health records. Choice C, higher risk of data breaches, is incorrect as EHRs have security measures in place to protect patient data. Choice D, more manual data entry, is incorrect as EHRs aim to automate and streamline data entry processes.
A client with a tumor refuses surgery, but the client's partner wants it. Which is the deciding factor in determining if the surgery will be done?
- A. Whether the partner is the client's durable power of attorney for healthcare
- B. Whether the client understands the risk of refusing the procedure
- C. Whether the client's refusal is based on religious belief
- D. Whether the facility's ethical committee reaches a consensus on the case
Correct Answer: B
Rationale: The correct answer is B because the client's understanding of the risks involved in refusing the surgery is crucial in determining the course of action. In this scenario, the client's autonomy and decision-making capacity take precedence. Choice A is not directly relevant to the decision-making process regarding surgery. Choice C, religious beliefs, may influence the decision but should not be the determining factor in this case. Choice D involving the facility's ethical committee is not typically involved in individual patient care decisions.
Dr. Shrunk orders intravenous (IV) insulin for Rita, a client with a blood sugar of 563. Nurse AJ administers insulin lispro (Humalog) intravenously (IV). What does the best evaluation of the nurse reveal? Select one that does not apply.
- A. The nurse could have given the insulin subcutaneously.
- B. The nurse did not have to contact the physician.
- C. The nurse should have used regular insulin (Humulin R).
- D. The nurse used the correct insulin.
Correct Answer: C
Rationale: The best evaluation of the nurse reveals that she should have used regular insulin (Humulin R) for IV administration. Regular insulin is the only insulin approved for intravenous administration due to its pharmacokinetic properties. Insulin lispro (Humalog) is not suitable for IV use. Choice A is incorrect because giving insulin intravenously is necessary in this case of high blood sugar. Choice B is incorrect because administering a different insulin without consulting the physician is not appropriate. Choice D is incorrect because the nurse used the incorrect insulin, which could pose risks to the client's health.
