Question 1 of 5
A 31-year-old woman is planning to take a 7-day cruise to the Caribbean islands. She has never been on a ship before and fears developing motion sickness. She purchases scopolamine transdermal patch. When is the best time for her to place the patch to maximize drug efficacy?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A 9-year-old boy is sent for neurologic evaluation because of episodes of apparent inattention. Over the past year, the child has experienced episodes during which he develops a blank look on his face and his eyes blink for 15 seconds. He immediately resumes his previous activity. Which one the following best describes this patient's seizures?
Correct Answer: D
Rationale: Absence seizures, typical in childhood, feature brief (10-20 second) lapses in awareness with staring and eye blinking, followed by immediate resumption of activity, as described. Simple partial seizures preserve consciousness with focal symptoms (e.g., twitching). Complex partial seizures impair awareness longer, with automatisms. Tonic-clonic seizures involve convulsions. Myoclonic seizures cause jerks without staring. The short duration, blank look, and rapid recovery align with absence seizures' EEG pattern (3 Hz spike-and-wave), distinguishing it here.
Question 3 of 5
Antihistamines block the actions of histamine at the
Correct Answer: A
Rationale: Antihistamines for allergies (e.g., diphenhydramine) target H1 receptors , blocking histamine's effects like itching or sneezing. B1 and B2 receptors (choices B, C) involve adrenergic responses (e.g., heart rate, bronchodilation), unrelated to histamine. C1 isn't a recognized receptor. H1 blockade is the mechanism for allergy relief, making choice A correct, reflecting antihistamines' specific pharmacological action critical for nurses to understand.
Question 4 of 5
A mother asks the nurse when she should give her child cough medicine. What is the best response by the nurse?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A client is prescribed clonidine (Catapres) for hypertension. Which statement by the client indicates effective teaching?
Correct Answer: C
Rationale: Clonidine, an alpha-2 agonist, lowers BP but risks rebound hypertension if stopped abruptly. Tapering off shows understanding, preventing this danger. Stopping if normal or extra doses risk instability. Chewing isn't advised'oral absorption suffices. Tapering aligns with clonidine's withdrawal risk, critical in hypertension management, making C the statement of effective teaching.
