Rationale: The therapeutic use of Alprazolam is for the relief of anxiety. Alprazolam belongs to a class of medications known as benzodiazepines, which are commonly prescribed to manage anxiety disorders and panic attacks. It works by enhancing the effects of a natural chemical in the body (GABA) to produce a calming effect on the brain and nerves, thereby alleviating symptoms of anxiety.

Rationale: Patients taking Angiotensin-converting enzyme (ACE) inhibitors should avoid salt substitutes because they can contain potassium chloride, which may lead to hyperkalemia. It is important to restrict potassium-rich foods while on ACE inhibitors, but the primary concern with salt substitutes is their potassium content.

Correct Answer: B

Rationale: The correct instruction for a client starting a new prescription for prednisone is not to stop taking the medication abruptly. Abrupt discontinuation of prednisone can lead to adrenal insufficiency, emphasizing the importance of gradual tapering under healthcare provider guidance. Increasing potassium-rich foods may be necessary based on individual needs, but it is not the priority instruction in this context. Grapefruit juice interaction is more commonly associated with certain medications but not specifically with prednisone. Taking prednisone at bedtime to prevent drowsiness is not a key instruction related to its administration.

Correct Answer: D

Rationale: When using Nitroglycerine (transdermal), it should be applied for 10-12 hours per day to ensure its effectiveness. A nitrate-free period within the day is essential to prevent the development of tolerance to the medication.

Correct Answer: C

Rationale: Metformin is commonly prescribed to manage and control blood glucose levels in individuals with diabetes. It helps in reducing the amount of glucose produced by the liver and improves the body's response to insulin, thereby aiding in the regulation of blood sugar levels. It is not used to lower blood pressure, diminish seizure activity, increase heart rate, or decrease gastrointestinal secretions.
