Extract:
Question 1 of 5
The nurse is performing education to a client diagnosed with Alzheimer's disease. Which of the following contraindications for anticholinergic would the nurse include for donepezil (Aricept)?
Correct Answer: C
Rationale: Glaucoma is a contraindication for the use of donepezil, an acetylcholinesterase inhibitor. Donepezil increases cholinergic activity, which can exacerbate symptoms in patients with glaucoma, particularly angle-closure glaucoma.
Question 2 of 5
A client frequently takes diphenhydramine (Benadryl) to alleviate his upper respiratory symptoms associated with allergies. Which of the following mechanisms of action applies to diphenhydramine (Benadryl)?
Correct Answer: D
Rationale: Blocking histamine receptors and inhibiting acetylcholine by binding to H1 receptors is the correct mechanism of action for diphenhydramine. This antihistamine drug effectively reduces allergic symptoms by preventing histamine from binding to H1 receptors. Additionally, diphenhydramine has anticholinergic effects, which means it can also inhibit the neurotransmitter acetylcholine, contributing to its sedative and anti-nausea properties. This dual action makes diphenhydramine effective in treating various allergic reactions and related symptoms.
Question 3 of 5
A client recently diagnosed with glaucoma is placed on a prostaglandin analogue. Which of the following medications would fall under the medication category prostaglandin analogue?
Correct Answer: B
Rationale: Bimatoprost is a prostaglandin analogue used to reduce intraocular pressure in patients with glaucoma or ocular hypertension.
Question 4 of 5
A nurse is teaching a group of nurses about the administration of nitroglycerin. Which of the following routes of administration provides the most rapid onset for the client?
Correct Answer: B
Rationale: Sublingual administration provides the most rapid onset of action for nitroglycerin. The medication is absorbed directly into the bloodstream through the mucous membranes under the tongue.
Question 5 of 5
A nurse is teaching a patient about the use of sildenafil (Viagra) for erectile dysfunction. Which statement by the patient indicates understanding of the teaching?
Correct Answer: C
Rationale: The statement about contacting a provider if an erection lasts longer than 6 hours indicates proper understanding. Prolonged erections, known as priapism, can be a serious side effect of sildenafil. It requires immediate medical attention to prevent permanent damage to the penis.
