Question 1 of 5
The parent of an adolescent with schizophrenia asks the nurse, “My child’s doctor ordered a PET. What kind of test is that?” Select the nurse’s best reply.
Correct Answer: B
Rationale: The correct answer is B because it provides an accurate and detailed explanation of what a PET scan is. Positron-emission tomography involves injecting a radioactive substance into the body to show blood flow and brain activity. This is crucial in diagnosing conditions like schizophrenia. Choice A is incorrect as it inaccurately describes a PET scan as similar to an MRI, which does not involve radioactive substances. Choice C is incorrect as a PET scan does not use X-rays to provide images. Choice D is incorrect as a PET scan does not measure electrical activity with scalp electrodes but rather shows blood flow and brain activity.
Question 2 of 5
A friend has just taken a night shift job and complains about increasing depression. The nurse responds, knowing that:
Correct Answer: C
Rationale: The correct answer is C because interrupted wake-sleep patterns can indeed influence mood. Night shift work disrupts the body's natural circadian rhythm, leading to sleep disturbances and affecting the production of neurotransmitters that regulate mood. This disruption can contribute to feelings of depression. Choice A is incorrect as there is a known connection between shift work and mental health. Choice B is incorrect because medication may not address the root cause of the depression in this case. Choice D is incorrect as adjustment to new sleep patterns can vary among individuals and may not necessarily take 4 months.
Question 3 of 5
While monitoring a depressed patient who has just started SSRI antidepressant therapy, the nurse will observe for which problem during the early time frame of this therapy?
Correct Answer: B
Rationale: The correct answer is B: Self-injury or suicidal tendencies. This is because during the early stages of SSRI antidepressant therapy, there is an increased risk of suicidal ideation and behavior before the full therapeutic effects are achieved. This is known as the "suicidal ideation paradox." The other options are incorrect because hypertensive crisis is not a common side effect of SSRI therapy, extrapyramidal symptoms are typically associated with antipsychotic medications, and loss of appetite is a common side effect but not specific to the early stages of SSRI therapy.
Question 4 of 5
A patient is in the intensive care unit and receiving an infusion of milrinone (Primacor) for severe heart failure. The prescriber has written an order for an intravenous dose of furosemide (Lasix). How will the nurse give this drug?
Correct Answer: C
Rationale: The correct answer is C: Administer the furosemide in a separate intravenous line. This is the correct approach to prevent potential drug interactions between milrinone and furosemide. Mixing the two drugs in the same IV line can lead to incompatibility issues or chemical reactions that may reduce the effectiveness of both medications. Administering furosemide in a separate IV line ensures that each medication is delivered as intended without compromising their therapeutic effects. Additionally, this method reduces the risk of line contamination and minimizes the potential for errors in drug administration. Therefore, it is crucial for the nurse to follow this protocol to ensure the safety and efficacy of the patient's treatment.
Question 5 of 5
A gardener needs a decongestant because of seasonal allergy problems and asks the nurse whether he should take an oral form or a nasal spray. The nurse’s answer considers that one benefit of orally administered decongestants is
Correct Answer: C
Rationale: The correct answer is C: lack of rebound congestion. Orally administered decongestants are less likely to cause rebound congestion compared to nasal sprays. This is because oral decongestants work systemically, targeting the whole body, whereas nasal sprays work locally, leading to potential rebound congestion when discontinued. Immediate onset (A) and potent effect (B) are not specific benefits of oral decongestants. Shorter duration (D) is also not a distinctive benefit of oral decongestants.
