Question 1 of 5
A patient with systemic candidiasis has been prescribed flucytosine. The nurse should be aware of the need to administer this drug with which of the following?
Correct Answer: C
Rationale: The correct answer is C: Amphotericin B. When treating systemic candidiasis, Amphotericin B is the drug of choice, not flucytosine. Amphotericin B is an antifungal medication used to treat severe fungal infections like systemic candidiasis. Choices A, B, and D are incorrect because vitamin D and calcium supplements, fluconazole, and penicillin G are not the drugs of choice for treating systemic candidiasis.
Question 2 of 5
The neurotransmitter GABA mainly functions to trigger inhibitory postsynaptic potentials (IPSPs). Therefore, when explaining this to a group of nursing students, the nurse will state:
Correct Answer: C
Rationale: When GABA binds with a receptor site, it causes hyperpolarization of the local nerve membrane, making it less excitable. This hyperpolarization leads to inhibition of nerve cell activity. Choice A is incorrect because GABA is a neurotransmitter itself and does not require three chemical substances to stimulate activity between cells. Choice B is incorrect as GABA triggers inhibitory postsynaptic potentials (IPSPs), leading to hyperpolarization, not depolarization, of the postsynaptic membrane. Choice D is also incorrect as it describes a process involving cholinergic receptors and acetylcholine, which is unrelated to GABA's mechanism of action.
Question 3 of 5
A client has been admitted to the hospital with symptoms of Guillain-Barr© syndrome. Which aspect of the client's condition would require priority monitoring?
Correct Answer: B
Rationale: In Guillain-Barr© syndrome, respiratory muscle weakness can lead to respiratory compromise, making it crucial to prioritize monitoring for signs of respiratory distress. Monitoring oxygen saturation levels is important but is secondary to assessing for respiratory compromise in this condition. Changes in consciousness and monitoring blood pressure closely are not typically the priority in Guillain-Barr© syndrome.
Question 4 of 5
A client with multiple sclerosis (MS) is experiencing a relapse. Which of the following factors is most likely contributing to the relapse?
Correct Answer: B
Rationale: Emotional stress can trigger a relapse in multiple sclerosis by exacerbating symptoms. While taking an over-the-counter multivitamin and getting a flu shot are generally safe, they are not typically known to trigger MS relapses. Engaging in strenuous physical activity, if done carefully, can actually have benefits for individuals with MS by improving strength and mobility, so it is less likely to be the cause of a relapse.
Question 5 of 5
A client with a pneumothorax is receiving oxygen therapy. Which assessment finding would indicate that the treatment is effective?
Correct Answer: C
Rationale: In a client with a pneumothorax receiving oxygen therapy, improved breath sounds on the affected side would indicate effective treatment. This finding suggests that the collapsed lung is re-expanding, allowing air to flow more freely in and out of the affected area. Choices A, B, and D are incorrect: Increased respiratory rate, decreased oxygen saturation levels, and increased dyspnea and chest pain are signs of ineffective treatment or worsening of the condition in a client with a pneumothorax.
