Question 1 of 5
How would you teach a patient how to prep an inhaler?
Correct Answer: B
Rationale: Teaching a patient how to prepare an inhaler is an important step in proper medication administration. Shaking the inhaler for about 5 seconds before use helps to ensure that the medication is properly mixed and dispersed. This is especially important for metered-dose inhalers where the medication is dispersed as a fine spray. Priming the inhaler by shaking it helps ensure that the patient receives the correct dose of medication with each use.
Question 2 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 3 of 5
Tricyclic antidepressants:
Correct Answer: C
Rationale: Tricyclic antidepressants (TCAs) like amitriptyline have a high volume of distribution due to lipophilicity, not low, making that false. They're not useful in urinary retention (they cause it as a side effect) but are effective for chronic pain via monoamine modulation, so that's partially false. They can prolong the QT interval by blocking cardiac sodium channels, a true statement and significant risk factor for arrhythmias. They don't block monoamine oxidase (MAO) but inhibit reuptake of norepinephrine and serotonin, increasing synaptic levels, so that's false. They treat severe depression, even with suicidal ideation, though caution is needed. The QT prolongation is a critical electrophysiological effect, requiring ECG monitoring in clinical use to prevent torsades de pointes.
Question 4 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 5 of 5
When collecting a medication history from a patient with primary open-angle glaucoma, the nurse identifies several drugs that could exacerbate glaucoma. Which drug poses a priority concern for this particular patient?
Correct Answer: B
Rationale: Oxymetazoline, a decongestant, can exacerbate glaucoma by causing vasoconstriction and increasing intraocular pressure. Cyclobenzaprine (
A) is not typically associated with worsening glaucoma. The nurse should prioritize identifying and addressing the use of oxymetazoline in this patient.
