Question 1 of 5
The nurse is assessing a client on a telemetry unit when the client states, "My vision is blurry, and I have been seeing yellow/green halos everywhere I look." Which of the following would the nurse suspect?
Correct Answer: D
Rationale: The correct answer is D: Digoxin (Lanoxin) toxicity. Blurred vision and seeing yellow/green halos are classic signs of digoxin toxicity. Digoxin can cause visual disturbances due to its effects on the optic nerve. Hyperglycemia (choice
A) typically does not present with visual disturbances. Captopril (choice
B) and Verapamil (choice
C) do not typically cause visual changes like halos. Digoxin toxicity (choice
D) is the most likely cause based on the client's symptoms.
Question 2 of 5
A client prescribed fluoxetine (Prozac) returns to the clinic one week after beginning therapy and states, "This drug is not working, I am still very sad." Which of the following would be the nurse's best response?
Correct Answer: D
Rationale: The correct answer is D: "This drug could take 4-6 weeks to begin working." This response is correct because fluoxetine, a selective serotonin reuptake inhibitor (SSRI), typically takes around 4-6 weeks to reach its full therapeutic effect. It is important for the nurse to educate the client on the delayed onset of action to manage expectations effectively.
Choice A is incorrect as adding another drug without giving fluoxetine an adequate trial period may not be necessary and could increase the risk of side effects.
Choice B is incorrect because while fluoxetine may start to show some effects within 1-3 weeks, the full therapeutic effect is generally achieved after 4-6 weeks.
Choice C is incorrect as switching to a different antidepressant prematurely may not be beneficial without giving fluoxetine sufficient time to work.
Question 3 of 5
A client is admitted to a hospital for treatment for first-time acute symptoms of mania. The nurse anticipates the provider will prescribe which of the following medications?
Correct Answer: A
Rationale: The correct answer is A: Lithium [Lithobid]. Lithium is a mood stabilizer commonly used to treat acute symptoms of mania. It helps in reducing manic episodes and stabilizing mood swings. Diazepam (
B) is a benzodiazepine used for anxiety and not recommended for mania. Bupropion (
C) is an antidepressant and not ideal for mania. Paroxetine (
D) is also an antidepressant and not the first-line treatment for mania.
Question 4 of 5
The clinic nurse is teaching a community class about Angiotensin-Converting Enzyme (ACE) inhibitors and Angiotensin II Receptor Blockers (ARBs). Which of the following should be included in the teaching?
Correct Answer: D
Rationale:
Correct
Answer: D. ARBs and ACE inhibitors are contraindicated during pregnancy.
Rationale: Both ARBs and ACE inhibitors are known to be harmful to the developing fetus and are contraindicated during pregnancy due to the risk of fetal harm, including birth defects and death. These medications can cause serious complications in pregnancy and should be avoided.
Summary of other choices:
A: Incorrect. Hypertension is not a side effect of these drugs but rather the condition they are used to treat.
B: Incorrect. Both ACE inhibitors and ARBs are used to treat heart failure.
C: Incorrect. WBC and potassium levels can be affected by these medications.
E, F, G: No information provided.
Question 5 of 5
A client is admitted to a hospital for treatment for first-time acute symptoms of mania. The nurse anticipates the provider will prescribe which of the following medications?
Correct Answer: A
Rationale: The correct answer is A: Lithium [Lithobid]. Lithium is a first-line treatment for acute mania due to its mood-stabilizing properties. It helps regulate neurotransmitter levels in the brain, particularly dopamine. It has a quick onset of action and is effective in managing manic symptoms. Diazepam (
B) is a benzodiazepine used for anxiety, not mania. Bupropion (
C) is an antidepressant and not typically used for mania. Paroxetine (
D) is an SSRI used for depression and anxiety, not mania. In summary, lithium is the correct choice due to its specific mood-stabilizing effects tailored for manic symptoms, while the other options are not appropriate for treating acute mania.
