Question 1 of 5
For the patient with hyperthyroidism, what intervention should you delegate to the experienced certified nursing assistant?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A nurse teaches an older woman who has a decreased production of estrogen. Which statement would the nurse include in this client’s teaching to decrease injury?
Correct Answer: B
Rationale: The correct answer is B. Daily exercise, such as walking, helps improve bone density and strength, reducing the risk of falls and fractures in older women with decreased estrogen production. Walking also helps maintain muscle strength and balance. A: Drinking fluids is important for overall health but does not directly address decreasing injury in this scenario. C: Bathing the perineal area twice a day is important for hygiene but does not specifically address decreasing injury. D: Checking blood glucose levels is important for diabetes management but is not directly related to decreasing injury in this case.
Question 3 of 5
A 59-year-old man complains of nocturia, urinary frequency, and an inability to urinate forcefully and empty his bladder. Following a complete workup, he was diagnosed with benign prostatic hypertrophy (BPH). We start daily therapy with tamsulosin. Which of the following is the most likely side effect the patient may experience from the tamsulosin, and about which he should be forewarned?
Correct Answer: C
Rationale: The correct answer is C: First dose hypotension. Tamsulosin is an alpha-1 blocker commonly used for BPH. It can cause orthostatic hypotension, especially after the first dose due to sudden vasodilation. This side effect is important to be forewarned about to prevent falls or accidents. Bradycardia (choice A) is not a common side effect of tamsulosin. Increased risk of statin-induced skeletal muscle pathology (choice B) is unrelated to tamsulosin. Photophobia and painful responses to bright lights (choice D) are not associated with tamsulosin use.
Question 4 of 5
The following sympathomimetic drug is a catecholamine:
Correct Answer: D
Rationale: Step-by-step rationale for why D (Isoprenaline) is the correct answer: 1. Isoprenaline is a catecholamine because it has a catechol structure, which consists of a benzene ring with two hydroxyl groups. 2. Catecholamines are a class of neurotransmitters that include dopamine, norepinephrine, and epinephrine. 3. Isoprenaline acts as a non-selective beta-adrenergic agonist, stimulating both beta-1 and beta-2 adrenergic receptors. 4. Its pharmacological effects include increased heart rate, bronchodilation, and vasodilation. Summary of why other choices are incorrect: A. Ephedrine is a sympathomimetic drug but is not a catecholamine as it lacks the catechol structure. B. Phenylephrine is a sympathomimetic drug that acts as an alpha-adrenergic agonist,
Question 5 of 5
Which of the following drugs is a direct stimulant of β1 and β2 adrenoceptors:
Correct Answer: B
Rationale: The correct answer is B: Isoprenaline. Isoprenaline directly stimulates both β1 and β2 adrenoceptors. It is a non-selective β-adrenergic agonist, leading to increased heart rate (β1 stimulation) and bronchodilation (β2 stimulation). Incorrect choices: A: Noradrenaline mainly acts on α-adrenoceptors. C: Salbutamol is a selective β2 agonist, not stimulating β1 receptors. D: Amphetamine primarily acts on catecholamine release and reuptake inhibition, not direct β-adrenoceptor stimulation.
