Nursing Elites

1. A woman with chronic osteoarthritis is complaining of knee pain. Which pathophysiological process is contributing to her pain?

• A. Inflammation of the synovial membrane.
• B. Degeneration of the cartilage in the joint.
• C. Joint inflammation occurs when chondrocyte injury destroys joint cartilage, producing osteophytes.
• D. Formation of uric acid crystals in the joint space.

Correct answer: C

Rationale: The correct answer is C. In osteoarthritis, the breakdown of cartilage in the joints leads to chondrocyte injury, which results in the destruction of joint cartilage and the production of osteophytes. This process causes joint inflammation and pain. Choice A is incorrect because osteoarthritis primarily involves the articular cartilage rather than the synovial membrane. Choice B is incorrect as it describes the degeneration of cartilage but does not explain the specific pathophysiological process contributing to pain in osteoarthritis. Choice D is incorrect as the formation of uric acid crystals is characteristic of gout, not osteoarthritis.

2. When planning care for a client newly diagnosed with open-angle glaucoma, the nurse identifies a priority nursing problem of visual sensory/perceptual alterations. This problem is based on which etiology?

• A. Limited eye movement.
• B. Decreased peripheral vision.
• C. Blurred distance vision.
• D. Photosensitivity.

Correct answer: B

Rationale: The correct answer is B: Decreased peripheral vision. In open-angle glaucoma, decreased peripheral vision is a characteristic symptom resulting from increased intraocular pressure. This visual impairment can lead to sensory/perceptual alterations. Choice A, limited eye movement, is not directly associated with the pathophysiology of open-angle glaucoma. Choice C, blurred distance vision, is more commonly seen in conditions like myopia or presbyopia. Choice D, photosensitivity, is not a typical manifestation of open-angle glaucoma and is more commonly associated with conditions like migraines or certain medications.

3. A client who had surgery yesterday is becoming increasingly anxious. The client’s respiratory rate has increased to 38 breaths/minute. The client has a nasogastric tube to low intermittent suction with 500 ml of yellow-green drainage over the last four hours. The client's arterial blood gases (ABGs) indicate a decreased CO2 and an increased serum pH. Which serum laboratory value should the nurse monitor first?

• A. Electrolytes.
• B. Creatinine.
• C. Blood urea nitrogen.
• D. Glucose.

Correct answer: A

Rationale: The correct answer is A, Electrolytes. In this scenario, the client is at risk for metabolic alkalosis due to the loss of gastric secretions through the nasogastric tube. Monitoring electrolytes is crucial to assess the levels of sodium, potassium, chloride, and bicarbonate, which are important in maintaining the acid-base balance of the body. Changes in these electrolyte levels can provide valuable information about the client's fluid status and acid-base balance. Creatinine, blood urea nitrogen, and glucose levels are important parameters to monitor in different situations but are not the priority in this case of potential metabolic alkalosis.

4. An adult woman with primary Raynaud phenomenon develops pallor and then cyanosis of her fingers. After warming her hands, the fingers turn red, and the client reports a burning sensation. What action should the nurse take?

• A. Apply a cool compress to the affected fingers for 20 minutes
• B. Secure a pulse oximeter to monitor the client's oxygen saturation
• C. Report the finding to the healthcare provider as soon as possible
• D. Continue to monitor the fingers until the color returns to normal

Correct answer: D

Rationale: In primary Raynaud phenomenon, the fingers go through a color sequence of pallor, cyanosis, and then redness when warmed. The burning sensation reported by the client indicates reperfusion. Continuing to monitor the fingers until the color returns to normal is appropriate in this situation as it ensures that the symptoms are resolving without the need for further intervention. Applying a cool compress could exacerbate the symptoms by causing vasoconstriction. Securing a pulse oximeter to monitor oxygen saturation is not necessary in this case as the issue is related to vasospasm rather than oxygenation. Reporting the finding to the healthcare provider is not urgent unless there are signs of complications or the symptoms do not improve with warming.

5. Which statement correctly explains the etiology of Down syndrome?

• A. There is an extra chromosome on the 21st pair.
• B. There is a missing chromosome on the 21st pair.
• C. There are two pairs of the 21st chromosome.
• D. The 21st chromosome pair is missing.

Correct answer: A

Rationale: The correct answer is A: 'There is an extra chromosome on the 21st pair.' Down syndrome is caused by the presence of an extra copy of chromosome 21, known as trisomy 21. This additional genetic material leads to the characteristics associated with Down syndrome. Choices B, C, and D are incorrect because Down syndrome is not due to a missing chromosome or having two pairs of the 21st chromosome; it results from the presence of an extra chromosome on the 21st pair.
