Question 1 of 5
A patient has been changed from a first generation H1 receptor antagonist to a second generation H1 receptor antagonist. The nurse evaluates that the patient understands the benefit of this change when which statement is made?
Correct Answer: D
Rationale: Second-generation antihistamines reduce sedation , a key benefit over first-generation. Alcohol , dry mouth , and urination aren't primary differences. D shows understanding, making it the best statement.
Question 2 of 5
The client receives alendronate (Fosamax) as treatment for osteoporosis. Which symptoms, caused by an adverse effect of the medication, does the nurse teach should be reported to the physician?
Correct Answer: C
Rationale: Alendronate's rare eye effects-vision changes, photophobia-signal inflammation, needing report, per safety. Ringing ears, hot skin, or spasms aren't linked-GI/esophageal issues dominate. Eye symptoms prompt action, per teaching.
Question 3 of 5
What is an adverse reaction to Montelukast? (select all that apply)
Correct Answer: B
Rationale: A. Stroke is not typically associated with an adverse reaction to Montelukast. The most common adverse reactions include neuropsychiatric events such as mood changes, suicidal thoughts/behaviors, and allergic reactions affecting the skin and mucous membranes.
Question 4 of 5
Lorazepam can be safely used as a preanesthetic medication in a patient undergoing liver transplantation without fear of excessive CNS depression because the drug is
Correct Answer: C
Rationale: Lorazepam is a benzodiazepine commonly used as a preanesthetic medication due to its anxiolytic and sedative properties. In patients undergoing liver transplantation, where hepatic function is compromised, drugs that rely on liver metabolism could accumulate and cause excessive central nervous system depression. Lorazepam's key advantage lies in its pharmacokinetic profile: it undergoes glucuronidation, a conjugation process that occurs outside the liver, primarily in the kidneys. This extrahepatic metabolism ensures that its clearance is less affected by liver dysfunction, reducing the risk of prolonged or excessive sedation. Unlike other benzodiazepines that depend heavily on hepatic cytochrome P450 enzymes, lorazepam's metabolism is more predictable in such patients, making it a safer choice. Excretion in unchanged form or secretion into the GI tract does not apply, and while it is anxiolytic, it does have CNS depressant effects, ruling out other options. Naloxone reverses opioids, not benzodiazepines.
Question 5 of 5
Which assessment should the nurse prioritize for a client receiving total parenteral nutrition (TPN)?
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.
