1. Which of the following joints normally allows 360-degree circumflexion?

• A. The knee
• B. The shoulder
• C. The elbow
• D. The fingertips

Correct answer: B

Rationale: The correct answer is B: The shoulder. The shoulder joint is a ball-and-socket joint that allows for a wide range of motion, including 360-degree circumflexion. This joint provides flexibility and mobility in various directions. Choice A, the knee joint, primarily allows flexion and extension but does not have a 360-degree circumflexion. Choice C, the elbow joint, is a hinge joint that permits flexion and extension but not circumflexion. Choice D, the fingertips, do not form a specific joint that allows circumflexion; rather, they have joints that enable bending and straightening movements.

2. 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.

3. A patient is admitted to the emergency department with hypovolemia. Which IV solution should the nurse anticipate administering?

• A. 3% sodium chloride
• B. 10% dextrose in water
• C. 0.45% sodium chloride
• D. Lactated Ringer's solution

Correct answer: D

Rationale: Lactated Ringer's solution is the most suitable IV solution for a patient with hypovolemia. It is a balanced crystalloid solution containing electrolytes such as sodium, chloride, potassium, calcium, and lactate, which closely resemble the body's natural fluids. This solution helps to restore intravascular volume and electrolyte balance in hypovolemic patients. Choice A, 3% sodium chloride, is a hypertonic solution used for specific situations like severe hyponatremia or cerebral edema, not typically for hypovolemia. Choice B, 10% dextrose in water, is a hypertonic solution primarily used for providing calories and free water, not for volume expansion. Choice C, 0.45% sodium chloride, is a hypotonic solution used for conditions like hypernatremia or as maintenance fluid, not for hypovolemia.

4. Which healthcare-associated infection poses the greatest risk for patients?

• A. Pneumonia
• B. Catheter-related infections
• C. Intravenous line infections
• D. C. difficile

Correct answer: B

Rationale: Catheter-related infections pose the greatest risk for patients in healthcare settings. Catheters are invasive devices that can introduce pathogens directly into the bloodstream, leading to severe infections. Pneumonia, intravenous line infections, and C. difficile infections are serious concerns as well, but catheter-related infections are particularly risky due to the direct access they provide for pathogens to enter the body.

5. A nurse is assessing a client who has meningitis. Which of the following findings should the nurse report to the provider immediately?

• A. Generalized rash over trunk
• B. Increased temperature
• C. Decreased level of consciousness
• D. Report of photophobia

Correct answer: C

Rationale: The correct answer is C: Decreased level of consciousness. In a client with meningitis, a decreased level of consciousness is a critical finding that should be reported immediately. This could indicate increased intracranial pressure or neurological deterioration, requiring prompt intervention. Choices A, B, and D are important in the assessment of meningitis but are not as immediately concerning as a decreased level of consciousness. A generalized rash over the trunk can be seen in meningococcal meningitis, an increased temperature is expected due to the inflammatory response, and photophobia is a common symptom due to meningeal irritation.
