Question 1 of 5
All are peripheral mediators of pain, except:
Correct Answer: D
Rationale: Peripheral mediators of pain can sensitize nociceptors and contribute to the perception of pain. Histamine, bradykinin, and prostaglandins are all examples of peripheral mediators that can induce pain. Amino acids, on the other hand, are not typically considered peripheral mediators of pain. While amino acids are important for many physiological processes in the body, they are not generally associated with the direct modulation of pain signaling pathways in the periphery.
Question 2 of 5
Which instruction is important for the nurse to include when teaching a patient about imatinib therapy?
Correct Answer: A
Rationale: Grapefruit juice can inhibit the metabolism of imatinib, leading to increased drug levels and a higher risk of side effects. Patients should be advised to avoid grapefruit juice while on imatinib therapy. Headaches are not typically an emergency unless severe or accompanied by other symptoms. Imatinib is a long-term treatment, not one that stops working after 2 months. Taking the drug on an empty stomach is not required; it can be taken with food to reduce gastrointestinal side effects.
Question 3 of 5
Which drug is most useful to prevent and treat cerumen impaction?
Correct Answer: A
Rationale: Hydrogen peroxide is commonly used to soften and remove cerumen (earwax) impaction due to its effervescent properties, which help break down the wax. Rubbing alcohol (B) is used for drying the ear canal but is not effective for cerumen impaction. Charcoal (C) and clove oil (D) are not used for this purpose.
Question 4 of 5
A patient has a new prescription for a blood pressure medication that may cause him to feel dizzy during the first few days of therapy. Which is the best nursing diagnosis for this situation?
Correct Answer: B
Rationale: Dizziness is a common side effect of many blood pressure medications, particularly during the initial days of therapy. This side effect increases the patient's risk of falls or other injuries, especially in elderly patients or those with mobility issues. The nursing diagnosis 'Risk for injury' is the most appropriate because it directly addresses the potential harm caused by dizziness. While 'Activity intolerance' and 'Self-care deficit' may be relevant in some cases, they do not specifically address the immediate risk posed by dizziness. 'Disturbed body image' is unrelated to this scenario. Therefore, 'Risk for injury' is the best diagnosis to guide nursing interventions, such as monitoring the patient and educating them on safety measures.
Question 5 of 5
Which of the following adverse effects is associated with levothyroxine (Synthroid) therapy?
Correct Answer: C
Rationale: Levothyroxine (Synthroid) is a synthetic thyroid hormone used to treat hypothyroidism. Overdose or excessive dosing can lead to symptoms of hyperthyroidism, including tachycardia (rapid heart rate), palpitations, and anxiety. Hypotension and bradycardia are not typical adverse effects of levothyroxine. Constipation is more commonly associated with hypothyroidism, not its treatment. Therefore, tachycardia is the correct answer as it reflects the potential for overstimulation of the cardiovascular system due to excessive thyroid hormone levels.
