The client is prescribed a nasal decongestant spray. What information should the nurse include when educating the client about how to use this medication?

Correct Answer: D

Rationale: Nasal decongestant sprays (e.g., oxymetazoline) risk rebound congestion if used beyond 3-5 days, and excess drainage into the mouth should be spat out to avoid systemic effects (correct answers: 1, 3, 5). Blowing the nose clears passages, and limiting use prevents rebound, both key. Water isn't relevant. Choice D ensures safe administration, minimizing ingestion risks.

Correct Answer: C

Rationale: The fundamental action of drugs that can be used as a substitute for what is lacking in the body falls under the category of Replacement. In medical terms, replacement therapy is a type of treatment that involves replacing a hormone or other important substance that is deficient or lacking in the body. For example, individuals with hypothyroidism are often prescribed levothyroxine as a replacement therapy to make up for the thyroid hormone deficiency in their body. Similarly, insulin is used to replace the deficient insulin in individuals with diabetes. Therefore, when drugs are administered to compensate for a deficiency or lack of a specific substance in the body, they are categorized under the fundamental action of Replacement.

Correct Answer: C

Rationale: The patient is experiencing gastrointestinal upset from taking aspirin. Enteric-coated aspirin would be a suitable alternative in this case because the special coating on the aspirin helps protect the stomach lining and reduces the risk of gastrointestinal irritation. Switching to an enteric-coated aspirin can still provide the antiplatelet benefits needed for secondary prevention of myocardial infarction while minimizing the gastrointestinal side effects. It is important to address the patient's symptoms while ensuring that they continue to receive appropriate treatment for their medical condition.

Correct Answer: A

Rationale: When a client receives total parenteral nutrition (TPN), monitoring blood glucose levels is critical due to the high glucose content in TPN solutions, which can lead to hyperglycemia. This condition arises because TPN delivers concentrated nutrients directly into the bloodstream, bypassing the digestive system, and the body may struggle to regulate sugar levels effectively without proper insulin response. Potassium levels, while important in overall electrolyte balance, are less immediately impacted by TPN compared to glucose, as potassium imbalances typically develop over time rather than acutely from TPN initiation. Mental status assessments are valuable for neurological conditions but lack direct relevance to TPN's metabolic effects. Similarly, blood pressure monitoring is essential for cardiovascular health but isn't the primary concern with TPN, as it doesn't directly influence hypertension or hypotension in the same way glucose dysregulation does. The focus on glucose stems from its rapid impact on the client's metabolic state, making it the priority assessment to prevent complications like hyperglycemia, which can escalate to severe outcomes if unaddressed. Regular monitoring ensures timely intervention, aligning with TPN's nutritional goals.

Correct Answer: C

Rationale: Flumazenil reverses benzo overdose (e.g., lorazepam) by blocking GABA receptors, countering sedation, per emergency protocol. Pralidoxime treats organophosphates. Naloxone and nalmefene target opioids, not benzos. Flumazenil fits, addressing overdose specifically.
