A patient with a diagnosis of peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?

Correct Answer: C

Rationale: The correct answer is C: Before meals. Omeprazole is a proton pump inhibitor that works by reducing stomach acid production. Taking it before meals allows the medication to be most effective in inhibiting the proton pumps before they are stimulated by food intake. This timing optimizes the drug's ability to reduce acid secretion during the digestion process. Choice A (With meals) is incorrect because taking omeprazole with meals may reduce its effectiveness as it will not have enough time to inhibit acid production before food intake. Choice B (At bedtime) is also incorrect as omeprazole works best when taken before meals to prevent acid production. Choice D (After meals) is incorrect because waiting until after meals to take omeprazole means that acid production has already been stimulated by the food consumed, reducing the drug's effectiveness in inhibiting acid secretion.

Correct Answer: B

Rationale: The correct answer is B: Maintain a consistent salt intake. Lithium can affect sodium levels in the body, so it's important to maintain a consistent salt intake to prevent lithium toxicity or imbalance. Increasing caffeine intake (choice A) can worsen symptoms of bipolar disorder. Avoiding dairy products (choice C) is not necessary for lithium therapy. Increasing intake of green leafy vegetables (choice D) is generally healthy but not specifically recommended for lithium therapy. Maintaining a consistent salt intake is crucial in managing the effects of lithium on sodium levels.

Correct Answer: B

Rationale: The correct answer is B: Rinse the mouth after using the inhaler. This instruction is crucial because corticosteroid inhalers can lead to oral thrush, a fungal infection in the mouth. Rinsing the mouth helps prevent this side effect. A: Using the inhaler only during asthma attacks is incorrect as corticosteroid inhalers are typically used regularly to manage asthma symptoms. C: Taking a double dose if symptoms worsen is dangerous and can lead to overdose. Patients should follow the prescribed dosage. D: Avoiding using a spacer with the inhaler is not a universal instruction. Spacers can actually improve the effectiveness of the medication delivery.

Correct Answer: A

Rationale: The correct answer is A: Take the medication with food. Allopurinol can cause stomach upset, so taking it with food can help minimize gastrointestinal side effects. Taking it on an empty stomach may increase the risk of nausea or stomach pain. Choice B is incorrect because increasing high-purine foods can exacerbate gout symptoms. Choice C is incorrect because limiting fluid intake can lead to dehydration, which is not recommended for gout patients. Choice D is incorrect because allopurinol does not provide immediate pain relief; it works to lower uric acid levels over time to prevent gout attacks.

Correct Answer: C

Rationale: The correct answer is C: Promote red blood cell production. Erythropoietin is a hormone that stimulates the bone marrow to produce more red blood cells, helping to treat anemia. It does not stimulate white blood cell production (A), increase platelet count (B), or enhance clotting factor production (D). White blood cells are involved in the immune response, platelets are responsible for clotting, and clotting factors are proteins involved in the blood clotting process. Therefore, the primary action of erythropoietin is to specifically target red blood cell production to address anemia.
