Question 2 of 5
A nursing student questions an instructor regarding the order for fluvoxamine (Luvox) 300 mg daily for a client diagnosed with obsessive-compulsive disorder (OCD). Which instructor response is most accurate?
Correct Answer: B
Rationale: The correct answer is B because SSRI doses higher than those used for depression are often needed to effectively treat OCD due to its different neurobiology. This is because OCD involves abnormalities in serotonin transmission, and studies have shown that higher doses of SSRIs can be more effective. Choice A is incorrect because tricyclic medications are not typically used as first-line treatment for OCD. Choice C is incorrect because daytime drowsiness is not a common side effect of Luvox. Choice D is incorrect because 300 mg daily dose of Luvox is within the therapeutic range for OCD treatment.
Question 3 of 5
Which action should be the nurse’s priority at this time?
Correct Answer: C
Rationale: The correct answer is C because increasing the level of suicide precautions is crucial for ensuring the client's safety. By enhancing precautions, the nurse can mitigate the risk of potential harm to the client. This action aligns with the principle of prioritizing safety and immediate needs in psychiatric care. Choice A is incorrect because giving off-unit privileges may not address the client's safety concerns. Choice B is incorrect as encouraging sharing in a group may not be the most urgent action when safety is a concern. Choice D is also incorrect as requesting a medication reevaluation may not directly address the immediate risk of harm to the client.
Question 4 of 5
A patient being treated for major depression is the CEO of her own business. She has shown significant improvement and is about to be discharged after completing a course of 15 electroconvulsive therapy sessions. She will continue on SSRI medications. The patient has been counseled not to make a major business decision for a month. The rationale for this is that:
Correct Answer: B
Rationale: The correct answer is B: ECT often causes temporary memory impairment. ECT is known to cause short-term memory loss and cognitive side effects. As the patient has just completed 15 sessions of ECT, it is important to allow time for her memory and cognitive function to recover before making major decisions. Choices A, C, and D are incorrect because SSRIs typically do not cause confusion, lingering depression alone does not make a person incompetent, and the patient's need for readjustment to work pressures is not directly related to the potential memory impairment caused by ECT.
Question 5 of 5
A patient is prescribed enoxaparin. The nurse knows that low-molecular-weight heparin has what kind of half-life?
Correct Answer: A
Rationale: The correct answer is A: A longer half-life than heparin. Enoxaparin, a low-molecular-weight heparin, has a longer half-life than unfractionated heparin due to its higher bioavailability and slower clearance. Enoxaparin's longer half-life allows for less frequent dosing compared to unfractionated heparin. Choice B is incorrect because low-molecular-weight heparin has a longer half-life than unfractionated heparin. Choice C is incorrect as low-molecular-weight heparin has a longer half-life than unfractionated heparin. Choice D is incorrect as it states that the half-life of enoxaparin is four times shorter than unfractionated heparin, which is not true.
