Nursing Elites

1. A healthcare professional is assessing a client with suspected myasthenia gravis. Which symptom would the healthcare professional expect to find?

• A. Muscle atrophy
• B. Facial weakness
• C. Ptosis and diplopia
• D. Increased muscle tone

Correct answer: C

Rationale: Ptosis (drooping eyelid) and diplopia (double vision) are classic symptoms of myasthenia gravis. Muscle atrophy (Choice A) is not a typical early manifestation of myasthenia gravis. While facial weakness (Choice B) can occur, it is not as specific as ptosis and diplopia. Increased muscle tone (Choice D) is more indicative of conditions like spasticity, not myasthenia gravis.

2. A patient being treated for tuberculosis is determined to be drug resistant. Which of the following medications will the patient be resistant to in the treatment of tuberculosis?

• A. Isoniazid (INH) and rifampin
• B. Carbamazepine (Tegretol) and phenytoin (Dilantin)
• C. Dextroamphetamine (Dexedrine) and doxapram (Dopram)
• D. Propranolol (Inderal) and sotalol (Betapace)

Correct answer: A

Rationale: In the treatment of tuberculosis, drug resistance commonly develops against medications like Isoniazid (INH) and rifampin. These two drugs are key components of the standard anti-tuberculosis treatment regimen. Choices B, C, and D are unrelated medications that are not used in the treatment of tuberculosis. Carbamazepine and phenytoin are anticonvulsants, dextroamphetamine is a stimulant, and propranolol and sotalol are used for cardiovascular conditions.

3. When reviewing the purpose/action of neurotransmitters as they interact with different receptors, the nursing instructor gives an example using acetylcholine. When acetylcholine is released at the sinoatrial node in the right atrium of the heart, it is:

• A. positively charged.
• B. inhibitory.
• C. overstimulated.
• D. dormant.

Correct answer: B

Rationale: Acetylcholine acts as an inhibitory neurotransmitter at the sinoatrial node. It slows down the heart rate by decreasing the firing rate of the sinoatrial node, which serves as the heart's natural pacemaker. Neurotransmitters do not have a charge, so choice A is incorrect. Choice C is wrong as overstimulation is not a characteristic of acetylcholine at the sinoatrial node. Choice D is also incorrect because acetylcholine actively influences heart rate regulation when released at the sinoatrial node.

4. A primiparous woman tells the nurse that she and her partner are highly reluctant to have their infant vaccinated, stating, “We've read that vaccines can potentially cause a lot of harm, so we're not sure we want to take that risk.” How should the nurse respond to this family's concerns?

• A. “Vaccinations are not without some risks, but these are far exceeded by the potential benefits they offer in preventing serious diseases.”
• B. “The potential risks of vaccinations have been investigated and determined to be minimal compared to the benefits of protecting your child from potentially life-threatening diseases.”
• C. “It is important to follow state laws regarding vaccines, but I understand your concerns. Let's discuss the specific risks and benefits of vaccines for your child.”
• D. “Vaccines indeed cause several serious adverse effects, but these are usually treated effectively, and the benefits of vaccination in preventing diseases far outweigh the risks.”

Correct answer: B

Rationale: When addressing concerns about vaccination, it is crucial to provide accurate information to help parents make informed decisions. Choice B is the most appropriate response as it acknowledges the concerns of the family while emphasizing that the potential risks of vaccinations are minimal compared to the significant benefits of protecting the child from serious diseases. This response shows empathy towards the parents' concerns while also highlighting the importance of vaccination in preventing life-threatening illnesses. Choice A is incorrect because it does not emphasize the significant benefits of vaccination in preventing diseases, which may not effectively address the family's concerns. Choice C is incorrect as it focuses more on state laws rather than addressing the family's specific concerns about vaccine safety. Choice D is incorrect as it may increase the family's anxiety by highlighting adverse effects without adequately emphasizing the benefits of vaccination in disease prevention.

5. While planning care for an elderly patient, the nurse remembers that increased age is associated with:

• A. Increased T cell function
• B. Increased immune function
• C. Increased production of antibodies
• D. Increased levels of circulating autoantibodies

Correct answer: D

Rationale: As individuals age, their immune function tends to decrease, making them more susceptible to infections and diseases. Additionally, increased age is associated with higher levels of circulating autoantibodies, which can lead to autoimmune conditions. Choice A is incorrect as aging is not typically associated with increased T cell function. Choice C is also incorrect as aging does not necessarily result in increased production of antibodies. Therefore, the correct answers are B (Decreased immune function) and D (Increased levels of circulating autoantibodies).
