Nursing Elites

1. Employee health test results reveal a tuberculosis (TB) skin test of 16-mm induration and a negative chest x-ray for a staff nurse working on the pulmonary unit. The nurse has no symptoms of TB. Which information should the occupational health nurse plan to teach the staff nurse?

• A. Standard four-drug therapy for TB
• B. Need for annual repeat TB skin testing
• C. Use and side effects of isoniazid (INH)
• D. Bacille Calmette-Gurin (BCG) vaccine

Correct answer: C

Rationale: The nurse is considered to have a latent TB infection and should be treated with INH daily for 6 to 9 months. The four-drug therapy would be appropriate if the nurse had active TB. TB skin testing is not done for individuals who have already had a positive skin test. BCG vaccine is not used in the United States for TB and would not be helpful for this individual, who already has a TB infection.

2. Which of the following components is associated with hypertonic dehydration?

• A. Plasma sodium levels above 150 mEq/L
• B. Fluid moves from extracellular space to intracellular space
• C. Water loss is greater than electrolyte loss
• D. Physical signs and symptoms are grossly apparent

Correct answer: C

Rationale: The correct answer is 'Water loss is greater than electrolyte loss.' In hypertonic dehydration, there is a higher loss of water compared to electrolytes, leading to elevated concentrations of electrolytes in the body. This condition is characterized by plasma sodium levels above 150 mEq/L. As water moves from the extracellular space to the intracellular space, it results in cellular dehydration. Choice A is incorrect because the plasma sodium levels associated with hypertonic dehydration are typically above 150 mEq/L, not between 130 and 150 mEq/L. Choice B is incorrect as fluid moves from the extracellular space to the intracellular space in hypertonic dehydration. Choice D is incorrect because physical signs and symptoms may not always be grossly apparent in hypertonic dehydration.

3. Which of the following statements best describes compartment syndrome?

• A. An injury causes pain and tingling that starts in the buttock and travels down the leg.
• B. An injury causes swelling within muscle tissue that leads to anoxia of nerves and muscles.
• C. An injury causes permanent flexion of the interphalangeal joint, resulting in deformity.
• D. An injury causes pain and swelling of the median plantar nerve.

Correct answer: B

Rationale: Compartment syndrome is characterized by swelling and increased pressure within a muscle compartment, leading to decreased blood flow and oxygen supply to nerves and muscles. This can result from various causes, such as trauma or the application of a cast after a fracture. If left untreated, compartment syndrome can lead to tissue necrosis. Choice A is incorrect as pain and tingling starting in the buttock and traveling down the leg are not specific features of compartment syndrome. Choice C is incorrect as permanent flexion of the interphalangeal joint is unrelated to compartment syndrome. Choice D is incorrect as pain and swelling of the median plantar nerve do not describe compartment syndrome.

4. A nursing student is teaching a patient and family about epilepsy prior to the patient's discharge. For which statement should you intervene?

• A. "You should avoid consumption of all forms of alcohol."?
• B. "Wear your medical alert bracelet at all times."?
• C. "Protect your loved one's airway during a seizure."?
• D. "It's important to consult with your physician before taking over-the-counter medications."?

Correct answer: D

Rationale: The correct answer is, "It's important to consult with your physician before taking over-the-counter medications."? Patients with epilepsy should not take over-the-counter medications without medical advice due to potential interactions with antiepileptic drugs or triggering seizures. Choices A, B, and C are all appropriate statements for a patient with epilepsy, focusing on alcohol avoidance, wearing a medical alert bracelet, and airway protection during a seizure, respectively. Choice D is incorrect because patients with epilepsy need to be cautious about medications due to possible interactions or adverse effects, so consulting with a physician is crucial before taking over-the-counter medications.

5. You are creating a teaching plan for a patient with newly diagnosed migraine headaches. Which key item should NOT be included in the teaching plan?

• A. Avoid foods that contain tyramine, such as alcohol and aged cheese.
• B. Avoid drugs such as Tagamet, nitroglycerin, and Nifedipine.
• C. Continue taking estrogen as prescribed by your physician.
• D. A potential side effect of medications is rebound headache.

Correct answer: C

Rationale: The correct answer is C: Continue taking estrogen as prescribed by your physician. Medications such as estrogen supplements may actually trigger a migraine headache attack. Fluctuations in estrogen, such as before or during menstrual periods, pregnancy, and menopause, seem to trigger headaches in many women. Choices A and B are important to include in the teaching plan for a patient with migraines as avoiding foods containing tyramine and certain drugs can help prevent migraine triggers. Choice D is also relevant as it is essential for the patient to be aware of potential side effects of medications, including rebound headaches.
