Nursing Elites

1. A patient scheduled for cataract surgery asks the nurse why they developed cataracts and how to prevent it in the future. What is the nurse's best response?

• A. Age is the biggest factor contributing to cataracts.
• B. Unprotected exposure to UV lights can cause cataracts.
• C. Age, eye injury, corticosteroids, and unprotected sunlight exposure are contributing factors to cataracts.
• D. Unfortunately, there is really nothing you can do to prevent cataracts, but they are amongst the most easily treated eye conditions.

Correct answer: C

Rationale: The correct answer is C: 'Age, eye injury, corticosteroids, and unprotected sunlight exposure are contributing factors to cataracts.' This response is the best choice as it covers the most common contributing factors for cataracts and includes preventable risk factors. Choice A is incorrect because while age is a significant factor in cataract development, it is not the only one. Choice B is incorrect as UV light exposure is a risk factor for cataracts but not the most comprehensive response. Choice D is incorrect as there are preventive measures individuals can take to reduce their risk of developing cataracts, such as protecting their eyes from UV light and managing other risk factors.

2. A diabetic patient's arterial blood gas (ABG) results are pH 7.28; PaCO2 34 mm Hg; PaO2 85 mm Hg; HCO3 18 mEq/L. The nurse would expect which finding?

• A. Intercostal retractions
• B. Kussmaul respirations
• C. Low oxygen saturation (SpO2)
• D. Decreased venous O2 pressure

Correct answer: B

Rationale: Kussmaul respirations (deep and rapid) are a compensatory mechanism for metabolic acidosis. The low pH and low bicarbonate levels indicate metabolic acidosis. Intercostal retractions, low oxygen saturation, and decreased venous O2 pressure are not associated with acidosis. Intercostal retractions typically occur in respiratory distress, while low oxygen saturation and decreased venous O2 pressure are more related to respiratory or circulatory issues, not metabolic acidosis.

3. A client with Multiple Sclerosis reports a constant, burning, tingling pain in the shoulders. The nurse anticipates that the physician will order which medication for this type of pain?

• A. alprazolam (Xanax)
• B. Corticosteroid injection
• C. gabapentin (Neurontin)
• D. hydrocodone/acetaminophen (Norco)

Correct answer: C

Rationale: For neuropathic pain associated with conditions like Multiple Sclerosis, medications like gabapentin, an anticonvulsant, are commonly used. Gabapentin helps in managing nerve pain by stabilizing electrical activity in the brain and nervous system. Alprazolam is a benzodiazepine used for anxiety and not primarily indicated for neuropathic pain. Corticosteroid injections are more suitable for inflammatory conditions like arthritis, not for neuropathic pain. Hydrocodone/acetaminophen is an opioid combination used for moderate to severe pain, but it is not the first-line choice for neuropathic pain.

4. Why should a 30-year-old Caucasian woman who works the night shift take Vitamin D supplements?

• A. It's a standard part of the overall nutritional treatment for the prevention of osteomalacia.
• B. It helps your intestines absorb calcium, which is important for bone formation.
• C. It stimulates skin cells to produce calcium, which is then released into the bloodstream to be used for bone formation.
• D. Vitamin D supplements should not be taken by someone of your age.

Correct answer: B

Rationale: The correct answer is B: 'It helps your intestines absorb calcium, which is important for bone formation.' Vitamin D plays a crucial role in aiding the absorption of calcium from the intestines into the bloodstream, which is essential for bone health and formation. Choice A is incorrect because it does not specifically address the role of Vitamin D in calcium absorption. Choice C is incorrect as Vitamin D does not stimulate skin cells to produce calcium; rather, it helps regulate calcium levels in the body. Choice D is incorrect as age alone is not a contraindication for Vitamin D supplementation; the need for supplementation is based on individual health status and risk factors.

5. Which of the following can cause coup-contrecoup injuries?

• A. Rotational forces
• B. Deformation forces
• C. Deceleration forces
• D. Acceleration forces

Correct answer: C

Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.
