What is one therapeutic use for nitroglycerin?

Correct Answer: A

Rationale: Nitroglycerin is primarily used for the relief or prevention of anginal attacks. It works by dilating blood vessels, increasing blood flow and oxygen to the heart muscle, thereby relieving chest pain caused by angina. The medication is not indicated for diuresis, antiemetic effects, or anxiety relief.

Correct Answer: C

Rationale: In pharmacology, when administering Lithium, a life-threatening side effect to be aware of is seizures. This is because Lithium can lead to neurotoxicity, manifesting as seizures, particularly if the serum levels of Lithium are elevated. Seizures are a serious medical emergency that requires immediate intervention to prevent further complications. Regarding the other options: A) Erythema: While skin rash can be a side effect of Lithium, it is not typically life-threatening unless it progresses to a severe allergic reaction like Stevens-Johnson syndrome. B) Pancreatitis: Lithium can affect the pancreas, but pancreatitis is not a common or immediate life-threatening side effect associated with Lithium use. D) Headache: Headache is a common side effect of many medications, including Lithium, but it is not typically life-threatening unless it is a symptom of a more severe condition. Educationally, understanding the potential life-threatening side effects of medications like Lithium is crucial for healthcare providers to ensure patient safety. It emphasizes the importance of monitoring patients closely, conducting regular assessments, and promptly addressing any concerning symptoms to prevent adverse outcomes.

Correct Answer: B

Rationale: In this scenario, option B, "I will be sure to take the albuterol before taking the cromolyn," is the correct answer. Albuterol is a short-acting beta agonist that works quickly to relieve acute bronchospasm in asthma, while cromolyn is a mast cell stabilizer that helps prevent asthma attacks. By taking albuterol first, the client ensures immediate relief of symptoms followed by the preventive action of cromolyn. Option A is incorrect because cromolyn is not for immediate relief but rather for long-term preventive use. Option C is incorrect as using both medications immediately after exercising is not necessary unless symptoms are present. Option D is incorrect as the medications do not need to be administered 10 minutes apart. Educationally, understanding the timing and purpose of medications in asthma management is crucial for optimal treatment outcomes. Teaching patients the correct sequence of medication administration empowers them to effectively manage their condition and improve compliance with their treatment plan.

Correct Answer: A

Rationale: Propranolol is contraindicated in clients with a history of asthma because it can cause bronchospasms due to its non-selective beta-blocking properties. By blocking beta-2 receptors in the lungs, propranolol can lead to bronchoconstriction, potentially triggering asthma symptoms and exacerbating respiratory issues. It is essential for individuals with asthma to avoid medications like propranolol that can worsen their condition.

Correct Answer: A

Rationale: Correct. Aluminum hydroxide is known to cause constipation as a common side effect. Instructing the client about this potential adverse effect is important for their awareness and management. Monitoring and managing constipation can help improve the client's comfort and overall treatment experience.
