Cardiovascular Treatment Drugs Questions
Question 1 of 5
An obese patient has schizophreni Medications that block which receptors would contribute to further weight gain?
Correct Answer: A
Rationale: The correct answer is A: H1 receptors. Blocking H1 receptors can lead to weight gain by increasing appetite and reducing energy expenditure. Histamine receptors play a role in regulating appetite and metabolism. Choices B, C, and D are incorrect. Blocking 5-HT2 receptors may cause weight loss, GABA receptors are not directly involved in weight regulation, and acetylcholine receptors do not significantly impact weight gain.
Question 2 of 5
A patient has been given succinylcholine (Anectine) after a severe injury that necessitated controlled ventilation. The physician now wants to reverse the paralysis. The nurse would expect to use which drug to reverse the succinylcholine?
Correct Answer: C
Rationale: The correct answer is C: neostigmine (Prostigmin). Neostigmine is a cholinesterase inhibitor that helps reverse the effects of succinylcholine by increasing acetylcholine levels at the neuromuscular junction. This leads to the competitive inhibition of succinylcholine, allowing the patient to regain muscle function. Valium (A) is a benzodiazepine used for anxiety and muscle relaxation, not for reversing paralysis. Caffeine (B) is a stimulant that does not reverse muscle paralysis. Vecuronium (D) is a non-depolarizing neuromuscular blocking agent and cannot reverse succinylcholine paralysis.
Question 3 of 5
The nurse is reviewing the JNC 7 guidelines for treatment of hypertension. Which blood pressure would be classified as “prehypertension” according to the JNC 7 guidelines?
Correct Answer: B
Rationale: The correct answer is B (130/88 mm Hg) because according to JNC 7 guidelines, prehypertension is defined as systolic blood pressure between 120-139 mm Hg and/or diastolic blood pressure between 80-89 mm Hg. Choice A (118/76 mm Hg) falls within the normal range. Choices C (150/90 mm Hg) and D (160/104 mm Hg) both fall within the hypertension range, not prehypertension.
Question 4 of 5
A patient with elevated lipid levels has a new prescription for nicotinic acid (niacin). The nurse informs the patient that which adverse effects may occur with this medication?
Correct Answer: A
Rationale: The correct answer is A: Pruritus, cutaneous flushing. Nicotinic acid commonly causes flushing due to prostaglandin release. Pruritus may also occur. B is incorrect as tinnitus and urine odor changes are not associated with nicotinic acid. C is incorrect as myalgia and fatigue are not common adverse effects. D is incorrect as blurred vision and headaches are not typically seen with nicotinic acid use. Therefore, A is the most appropriate choice based on the common adverse effects of nicotinic acid.
Question 5 of 5
The nurse is preparing to administer morning medications to a patient who has been newly diagnosed with tuberculosis. The patient asks, “Why do I have to take so many different drugs?” Which response by the nurse is correct?
Correct Answer: B
Rationale: The correct answer is B: "Taking multiple drugs reduces the chance that the tuberculosis will become drug resistant." Rationale: 1. Combination therapy is essential in treating tuberculosis to prevent the development of drug resistance. 2. Different drugs target various stages of the tuberculosis bacteria's life cycle, reducing the likelihood of resistance. 3. Using a single drug can lead to the bacteria adapting and becoming resistant, making treatment ineffective. 4. Option A is incorrect because relying on just one drug is not effective in preventing drug resistance. 5. Option C is incorrect as using multiple drugs does not necessarily reduce side effects; it primarily aims to prevent resistance. 6. Option D is incorrect because the main goal of using multiple drugs is not to enhance the effect of each drug but to prevent drug resistance.
