Question 1 of 5
Which of the following assessment findings is a priority for the nurse to follow-up?
Correct Answer: D
Rationale: The correct answer is D: Complains of muscle weakness. Muscle weakness can indicate a serious underlying condition that requires immediate attention. It could be a sign of neurological issues, electrolyte imbalances, or other systemic problems. It is crucial for the nurse to follow up on this symptom promptly to assess the severity, potential causes, and appropriate interventions.
A: Blood pressure 130/80 is within normal limits and does not require immediate follow-up.
B: Knee pain rated 5/10 is important but not as urgent as muscle weakness.
C: Hypoactive bowel sounds X4 may indicate gastrointestinal issues, but muscle weakness takes precedence due to its potential severity.
Question 2 of 5
The client is in a manic phase of bipolar disorder, and is receiving lithium. What will the nurse expect to assess when the client's lithium level is 0.3 mEq/L?
Correct Answer: D
Rationale: The correct answer is D: Hyperactivity. At a lithium level of 0.3 mEq/L, the client is likely to exhibit symptoms of hyperactivity due to subtherapeutic levels of lithium. This is because lower lithium levels may not effectively control the manic symptoms in bipolar disorder. Sleepiness (
A), relaxed appearance (
B), and calm behavior (
C) are more indicative of sedative effects often seen at higher, toxic levels of lithium, not at 0.3 mEq/L.
Therefore, hyperactivity is the most likely assessment finding at this particular lithium level.
Question 3 of 5
The nurse is caring for a client diagnosed with bipolar disorder who is exhibiting the following symptoms: insomnia, exaggerated confidence, attention seeking, and easily agitated. Based on these symptoms, what does the nurse believe these symptoms are caused by?
Correct Answer: B
Rationale: The correct answer is B: Mania. Mania is a hallmark symptom of bipolar disorder characterized by symptoms such as insomnia, exaggerated confidence, attention seeking, and easily agitated behavior. These symptoms align with the manic phase of bipolar disorder, where individuals experience elevated mood, increased energy, and impulsivity. Overdose of barbiturates (
A) would typically present with symptoms like drowsiness, confusion, and respiratory depression. Side effects of lithium (
C) are more likely to cause symptoms such as tremors, thirst, and weight gain. Depression (
D) presents with symptoms such as low mood, fatigue, and feelings of worthlessness, which are contrary to the symptoms described in the scenario.
Question 4 of 5
A patient asks how most antidepressants work. The nurse responds by saying that antidepressants improve mood by increasing levels of:
Correct Answer: C
Rationale: The correct answer is C: Norepinephrine and serotonin. Most antidepressants work by increasing the levels of norepinephrine and serotonin in the brain. Norepinephrine and serotonin are neurotransmitters that play key roles in regulating mood, emotions, and feelings of well-being. By increasing the levels of these neurotransmitters, antidepressants help to restore the balance of chemicals in the brain, ultimately improving mood and reducing symptoms of depression.
Choices A and B are incorrect because GABA and epinephrine are not the primary neurotransmitters targeted by antidepressants.
Choice D is incorrect because the reticular formation is not directly involved in the mechanism of action of antidepressants.
Question 5 of 5
The nurse is educating a group of clients on how high cholesterol leads to heart disease. Which explanation regarding high cholesterol is most appropriate?
Correct Answer: A
Rationale: The correct answer is A because high cholesterol can lead to atherosclerosis, where cholesterol builds up on vessel walls, narrowing them and reducing blood flow to the heart. This can lead to heart disease.
Choice B is incorrect because high cholesterol does not directly damage the heart muscle itself.
Choice C is incorrect as high cholesterol does not thicken the blood but rather contributes to plaque formation on vessel walls.
Choice D is incorrect as high cholesterol does not interfere with the heart's conduction system, which controls the heart's rhythm.
