Correct Answer: B

Rationale: The correct response is B: Feverfew is commonly used to decrease the frequency of migraine headaches. However, it is important to note that it has not been proven to relieve an existing migraine headache. Choices A, C, and D are incorrect as Feverfew is not typically used for treating skin infections, lessening nasal congestion in the common cold, or relieving nausea of morning sickness during pregnancy.

Correct Answer: A

Rationale: The correct answer is to instruct the client to avoid taking aspirin while on Clopidogrel. Clopidogrel is an antiplatelet medication that can increase the risk of bleeding. Aspirin and other NSAIDs can further potentiate this risk, so they should be avoided while taking Clopidogrel to reduce the chance of bleeding complications. Choices B, C, and D are incorrect. There is no specific instruction to take Clopidogrel with food or at bedtime. Avoiding foods high in potassium is not directly related to Clopidogrel use.

Correct Answer: C

Rationale: The correct instruction that the nurse should include when providing discharge instructions for a client with a Fentanyl transdermal patch is to avoid exposure to heat sources. Heat can increase the absorption of the medication, leading to a risk of overdose. Choice A is incorrect because the patch should be applied to a clean, non-hairy area. Choice B is incorrect as the Fentanyl patch is usually changed every 72 hours, not every 24 hours. Choice D is incorrect as the patch should never be cut to adjust the dosage.

Correct Answer: A

Rationale: The priority assessment for a healthcare provider preparing to administer an IV bolus of Morphine is the client's respiratory rate. Morphine can cause respiratory depression as a significant adverse effect, so monitoring the respiratory rate is crucial to detect any signs of respiratory compromise and intervene promptly. Assessing the respiratory rate takes precedence over other assessments because respiratory depression can lead to serious complications. While pain level, blood pressure, and level of consciousness are important assessments, they are not the priority when administering Morphine, as the risk of respiratory depression is a more immediate concern.

Correct Answer: A

Rationale: The correct answer is A. Terbutaline works by blocking beta2-adrenergic receptors, leading to uterine smooth muscle relaxation and stopping contractions. It is commonly used to delay preterm labor. Choice B is incorrect because Terbutaline is not used to prevent vaginal bleeding. Choice C is incorrect because Terbutaline's primary action is not related to promoting blood flow to the baby. Choice D is incorrect because Terbutaline does not increase prostaglandin production; instead, it works by blocking beta2-adrenergic receptors.
