Question 1 of 5
The following hypotensive combinations are rational when a single drug has not been effective in treating essential hypertension except:
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A patient admitted to the emergency department following a drug overdose. He has severe tachycardia. He has been receiving therapy for hypertension and angina. A drug that often causes tachycardia is:
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A client who has been hospitalized for mania in the past is laid off from her job. She becomes very depressed, refuses to look for another job, stays in her room, eats very little, and neglects her personal hygiene. The client is found unconscious, but still breathing, with an empty bottle of sertraline (Zoloftâ) beside her. She is stabilized in an emergency department and is then admitted to a psychiatric unit with a diagnosis of bipolar I disorder, current episode depressed. Which should be the priority nursing diagnosis for this client?
Correct Answer: C
Rationale: The priority nursing diagnosis for the client in this scenario should be "C: Risk for suicide related to depressed mood." This is because the client's current state of depression, along with the attempted overdose of sertraline, indicates a significant risk of self-harm. Addressing this risk should be the primary focus to ensure the client's safety and well-being. Choice A is incorrect because although the client is not eating much, the immediate concern is the risk of suicide rather than nutrition. Choice B is incorrect as the client's self-esteem is not the primary concern in this situation compared to the risk of self-harm. Choice D is incorrect as the client's symptoms are more indicative of a depressive episode rather than grief over job loss.
Question 4 of 5
To evaluate outcomes for a patient with schizophrenia receiving typical antipsychotic drug therapy, the nurse would look for improvement in:
Correct Answer: B
Rationale: The correct answer is B: Positive symptoms. Positive symptoms of schizophrenia include hallucinations, delusions, and disorganized thinking. Improvement in positive symptoms indicates that the antipsychotic drug therapy is effective in managing the core symptoms of schizophrenia. Affective mobility (choice A) refers to the range and intensity of emotions, which may not directly reflect the effectiveness of antipsychotic therapy. Self-care activities (choice C) and cognitive functioning (choice D) are important aspects to monitor in schizophrenia treatment, but improvement in positive symptoms is a more direct indicator of treatment efficacy.
Question 5 of 5
A patient is taking a potassium-depleting diuretic and digoxin. The nurse expects that a low potassium level (hypokalemia) could have what effect on digoxin?
Correct Answer: A
Rationale: The correct answer is A because hypokalemia can lead to increased sensitivity to digoxin, potentially causing digoxin toxicity. Low potassium levels impair the function of the sodium-potassium pump, which is crucial for maintaining the appropriate intracellular sodium and potassium levels. This can result in increased binding of digoxin to sodium-potassium ATPase, leading to enhanced digoxin effects. Option B is incorrect because hypokalemia would not decrease digoxin sensitivity; in fact, it would likely increase sensitivity. Option C is incorrect as hypokalemia does have an effect on digoxin sensitivity. Option D is incorrect because hypokalemia does not cause a low-average serum digoxin sensitivity level; it actually increases sensitivity.
