Question 1 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 2 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.
Question 3 of 5
A nurse instructs a patient taking a drug that inhibits monoamine oxidase (MAO) to avoid certain foods and drugs because of the risk of:
Correct Answer: C
Rationale: Rationale for Correct Answer (C): MAO inhibitors prevent the breakdown of monoamines, leading to increased levels of norepinephrine and tyramine. Ingesting tyramine-rich foods or drugs can cause a sudden and dangerous rise in blood pressure, resulting in a hypertensive crisis. This is because tyramine displaces norepinephrine, leading to excessive vasoconstriction and increased blood pressure. Incorrect Choices: A: Cardiac dysrhythmia is not directly associated with MAO inhibitors. B: Hypotensive shock is contradictory as MAO inhibitors increase blood pressure. D: Cardiogenic shock is not a typical risk associated with MAO inhibitors.
Question 4 of 5
A genetic counselor is called by the hospital to see patients with genetic questions or concerns. With which patient would it be most appropriate for the counselor to speak?
Correct Answer: A
Rationale: The correct answer is A because a pregnant patient with multiple sclerosis may have concerns about the impact of their condition and potential genetic risks for the baby. The genetic counselor can provide information on genetic factors, potential risks, and support options for the patient and their family. Incorrect choices: B: While mental health is important, a genetic counselor is not the most appropriate professional to address a recent suicide attempt. C: The number of drugs prescribed does not directly relate to genetic counseling needs. D: Schizophrenia and multiple hospital admissions may require psychiatric care but do not necessarily warrant genetic counseling unless there are specific genetic concerns related to the condition.
Question 5 of 5
A patient is to receive local anesthesia for removal of a lymph node from his armpit. The physician asks for a solution of premixed lidocaine and epinephrine. The nurse knows that the epinephrine is used for which reason?
Correct Answer: D
Rationale: The correct answer is D because epinephrine is added to lidocaine to vasoconstrict blood vessels, keeping the anesthetic at its local site of action and decreasing incisional bleeding. This helps prolong the duration of anesthesia and reduces the risk of systemic toxicity. A: Incorrect. Epinephrine does not prevent an anaphylactic reaction; it is added for vasoconstrictive effects. B: Incorrect. The anesthetic does not enhance the effect of epinephrine. They have separate roles. C: Incorrect. Epinephrine does not contribute to a balanced anesthetic state; it primarily acts on blood vessels.
