Extract:
Question 1 of 5
A nurse is providing an in-service about cancer. Which of the following statements is true regarding metastasis?
Correct Answer: A
Rationale: The correct answer is A. Metastasis is the process where cancerous cells spread from the primary tumor to other parts of the body, invading nearby tissues and forming new tumors. This is a critical aspect of cancer progression and is responsible for the majority of cancer-related deaths.
Choice B is incorrect because normal cells do not spread in the same way as cancerous cells.
Choice C is incorrect as metastasis involves the spread of cancerous cells, not normal cells.
Choice D is incorrect as metastasis does not involve treating malignant tumors; it is the spread of cancer cells.
Question 2 of 5
A nurse is educating a client about a new prescription for morphine. Which of the following statements should the nurse include in the teaching about this medication?
Correct Answer: B
Rationale: The correct answer is B: Morphine acts as an agonist on the mu and kappa receptors. This statement is important to include in the teaching because it explains how morphine works pharmacologically by binding to specific opioid receptors (mu and kappa receptors) to produce its analgesic effects. Understanding this mechanism of action is crucial for the client to grasp how the medication alleviates pain.
Incorrect Answers:
A: Morphine actually has a high potential for abuse and can cause significant euphoria.
C: Morphine is a potent analgesic and is generally more effective than butorphanol.
D: Morphine is primarily used for pain relief, not to prevent fevers.
Question 3 of 5
Which of the following medications is an inhaled agent used for long-term prophylaxis of asthma?
Correct Answer: A
Rationale: The correct answer is A: Beclomethasone (QVAR). Beclomethasone is a corticosteroid inhaler used for long-term asthma control by reducing inflammation and preventing asthma symptoms. It is not used for immediate relief. Metoprolol (
B) is a beta-blocker for hypertension, not asthma. Phenytoin (
C) is an antiepileptic drug. Furosemide (
D) is a diuretic for managing fluid retention, not asthma. Beclomethasone is the appropriate choice for long-term asthma prophylaxis due to its anti-inflammatory properties in the airways.
Question 4 of 5
A nurse is caring for a client with a new prescription for sumatriptan (Imitrex). Which of the following is an indication of sumatriptan (Imitrex)?
Correct Answer: B
Rationale: The correct answer is B: Treatment of migraines. Sumatriptan (Imitrex) is a medication commonly used to treat migraines by targeting the blood vessels and reducing inflammation associated with migraine headaches.
Choice A is incorrect because sumatriptan is not used to treat opioid use disorder.
Choice C is incorrect because while sumatriptan can provide pain relief, it is primarily used for migraines specifically.
Choice D is incorrect because sumatriptan is not indicated for all the mentioned conditions, only for migraines.
Question 5 of 5
A nurse is caring for a client with allergic rhinitis. The client is newly prescribed guaifenesin. What is the medication class for this medication?
Correct Answer: D
Rationale: The correct answer is D: Expectorant. Guaifenesin is an expectorant that helps loosen and thin mucus in the airways, making it easier to cough up. Decongestants (
A) reduce nasal congestion, mucolytics (
B) help break down mucus, and antitussives (
C) suppress coughing. In summary, guaifenesin is classified as an expectorant because it helps with mucus clearance in allergic rhinitis.
