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.

Correct Answer: A

Rationale: The correct answer is A: 'Take this medication before meals.' Omeprazole is a proton pump inhibitor that should be taken before meals to be most effective in reducing stomach acid production. Taking it before meals allows the medication to inhibit the proton pumps in the stomach when they are most active, leading to better control of acid secretion. Choice B is incorrect because taking Omeprazole with food may reduce its effectiveness as food can interfere with its absorption. Choice C is incorrect as Omeprazole is more effective when taken before meals. Choice D is incorrect as Omeprazole should not be taken with antacids as they can reduce its absorption.

Correct Answer: A

Rationale: The healthcare professional should instruct the client to report dyspnea since it can indicate pulmonary toxicity, a severe adverse effect associated with gemcitabine therapy. Monitoring and reporting dyspnea promptly can help in early detection and management of potential serious complications. Constipation, tinnitus, and dry mouth are not typically associated with gemcitabine therapy and are not urgent findings requiring immediate reporting.

Correct Answer: A

Rationale: The nurse should instruct the client to take folic acid when receiving treatment with methotrexate to reduce the risk of methotrexate toxicity. Methotrexate acts as a folic acid antagonist, leading to folic acid deficiency, which can be counteracted by supplementing with folic acid. Vitamin D, calcium, and iron are not specifically recommended to counteract methotrexate effects and do not play a significant role in mitigating methotrexate toxicity.

Correct Answer: C

Rationale: The correct answer is C: Cough. Lisinopril, an ACE inhibitor, commonly causes a persistent dry cough as an adverse effect. Clients should be informed to monitor for this side effect and report it to their healthcare provider if it occurs. Choices A, B, and D are incorrect because tinnitus, diarrhea, and weight gain are not commonly associated with Lisinopril therapy.
