Correct Answer: D

Rationale: Omeprazole is a proton pump inhibitor that works by reducing gastric acid secretion. By inhibiting the enzyme responsible for pumping acid into the stomach, omeprazole helps decrease the acidity level in the stomach, providing relief from peptic ulcers. Option A is incorrect because omeprazole does not increase gastric acid production; instead, it decreases it. Option B is incorrect as omeprazole does not neutralize existing stomach acid but rather reduces its secretion. Option C is incorrect as omeprazole does not coat the stomach lining but acts on reducing acid secretion.

Correct Answer: B

Rationale: The correct response is to provide instructions on managing these side effects. Sensitivity to light and dry mouth are common side effects of anticholinergic medications like dicyclomine. It is essential for the nurse to educate the patient on strategies to cope with these side effects, such as staying hydrated to address dry mouth and wearing sunglasses to reduce sensitivity to light. Option A is not the priority as the side effects are expected with this medication and do not necessarily indicate incorrect use. Option C is not immediately necessary as the side effects are common and can be managed without a healthcare provider evaluation. Option D is not recommended unless advised by the healthcare provider as abruptly stopping the medication can lead to worsening symptoms or withdrawal effects.

Correct Answer: A

Rationale: The correct answer is A: Tremors. Albuterol, a beta-agonist medication commonly used to treat asthma exacerbations, can lead to tremors as a side effect. Tremors result from the stimulation of beta-2 receptors in muscles, particularly in the hands. Nausea and vomiting (Choice B) are generally not common side effects of albuterol. Insomnia (Choice C) is less likely to occur with albuterol, as it is a stimulant and can cause alertness rather than sleep disturbances. Dry mouth (Choice D) is not a typical side effect associated with albuterol use.

Correct Answer: D

Rationale: The correct instruction to include in the teaching plan for a client prescribed sitagliptin is to report any signs of pancreatitis to the healthcare provider. Sitagliptin is generally taken with meals to reduce gastrointestinal side effects. Therefore, choice A, 'Take this medication with meals,' is incorrect. Sitagliptin does not have specific interactions with alcohol, so there is no need to advise the client to avoid alcohol, making choice B incorrect. Taking sitagliptin on an empty stomach is not recommended, so choice C is also incorrect. Pancreatitis is a rare but serious side effect of sitagliptin, so it is crucial for the client to report any signs or symptoms to their healthcare provider promptly.

Correct Answer: A

Rationale: The correct answer is A: Hypotension. Clonidine, a medication used to treat hypertension, can cause a lowering of blood pressure leading to hypotension as a potential side effect. Monitoring for hypotension is essential to prevent complications such as dizziness, fainting, or falls. Option B, Tachycardia, is incorrect as clonidine typically causes bradycardia or a decreased heart rate. Option C, Dizziness, can occur due to hypotension caused by clonidine. Option D, Hyperglycemia, is not a common side effect associated with clonidine use.
