Question 1 of 5
A nurse is providing instructions to a client who is taking doxapram (Dopram). Which of the following statements made by the client needs further instructions?
Correct Answer: B
Rationale: Doxapram (Dopram) is a respiratory stimulant medication used to treat respiratory depression. It is usually taken during the day, as it can cause stimulation and increased alertness. Taking it at bedtime may lead to difficulty falling asleep or staying asleep due to its stimulating effects. Therefore, the client should be instructed to take the medication during the day and not at bedtime.
Question 2 of 5
The nurse teaches the client about the difference between oral and nasal decongestants. The nurse evaluates that learning has been effective when the client makes which statement?
Correct Answer: A
Rationale: Oral decongestants (e.g., pseudoephedrine) act systemically, raising blood pressure via vasoconstriction, a key difference from nasal decongestants (e.g., oxymetazoline), which act locally but risk rebound congestion. The statement 'Oral decongestants can cause hypertension' shows the client grasps this systemic effect, indicating effective teaching. Nasal decongestants aren't safe for a month ; they cause rebound after 3-5 days. Only nasal decongestants typically cause rebound , not oral. Oral efficacy varies, not inherently superior. Choice A reflects accurate understanding of oral decongestants' broader impact, critical for safe use, making it the best learning indicator.
Question 3 of 5
The plasma clearance of a drug:
Correct Answer: A
Rationale: Plasma clearance reflects the volume of plasma cleared of the drug per unit time, combining renal and hepatic elimination pathways.
Question 4 of 5
What patient history would the nurse recognize as a contraindication for beginning Niacin therapy?
Correct Answer: B
Rationale: Gout is a contraindication for beginning Niacin therapy due to its potential to exacerbate gout symptoms. Niacin can lead to hyperuricemia, which is increased uric acid levels in the blood, and that can trigger a gout attack. Patients with a history of gout should avoid Niacin therapy to prevent worsening of their condition.
Question 5 of 5
When taking Digoxin, low levels of what can cause
Correct Answer: A
Rationale: When taking digoxin, low levels of potassium can cause an increased risk of digoxin toxicity. This is because digoxin and potassium compete for binding sites on the sodium-potassium pump in cardiac cells. Low potassium levels can lead to enhanced binding of digoxin to these pumps, resulting in increased concentrations of digoxin within the cells and potential toxicity. Therefore, it is important to monitor potassium levels regularly while taking digoxin to prevent complications.
