Pharmacology Across the Lifespan Quizlet Questions
Question 1 of 5
What is the first line therapy when treating hyperlipidemia?
Correct Answer: C
Rationale: The correct answer is C: Lifestyle modifications. This is because lifestyle modifications, such as healthy diet and regular exercise, are the first line therapy for hyperlipidemia. These interventions can help lower cholesterol levels without the need for medication. Bile Acid Sequestrants (A) and Niacin (D) are less commonly used due to side effects and limited efficacy compared to statins. Statin Therapy (B) may be considered as second-line therapy if lifestyle modifications are not sufficient to reach target lipid levels.
Question 2 of 5
Which best describes the action of ACE inhibitors on the failing heart?
Correct Answer: D
Rationale: The correct answer is D: ACE inhibitors reduced preload. ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II, which leads to vasodilation and reduced preload on the heart. This results in decreased workload for the failing heart, improving its function. Explanation for why other choices are incorrect: A: ACE inhibitors do not increase aldosterone. In fact, they decrease aldosterone levels by inhibiting angiotensin II, which stimulates aldosterone release. B: ACE inhibitors do not increase vascular resistance. They actually reduce vascular resistance by blocking the vasoconstrictive effects of angiotensin II. C: ACE inhibitors do not decrease cardiac output. They may initially cause a slight decrease due to reduced preload, but overall they improve cardiac output by reducing the workload on the heart.
Question 3 of 5
Below question: don't know the correct combination. Below is what was picked but incorrect. The patient who has been prescribed lithium for a diagnosis of bipolar disorder asked why blood tests are required on a regular basis. Which provider responses demonstrate an understanding of why the patient requires a variety of laboratory tests? Select all that apply
Correct Answer: A
Rationale: The correct answer is A because lithium can affect thyroid function, leading to hypothyroidism. Monitoring thyroid levels is crucial to detect any abnormalities early and adjust treatment accordingly. Choice B, C, and D are incorrect as they do not address the specific reason for requiring regular blood tests in a patient prescribed lithium for bipolar disorder.
Question 4 of 5
ED50 refers to:
Correct Answer: C
Rationale: The correct answer is C: The median effective dose. ED50 refers to the dose of a drug that is required to produce a therapeutic effect in 50% of the population or experimental animals. This is a measure of the potency of a drug. The other choices are incorrect because: A: Half-life of the drug does not specifically refer to ED50. B: Half of the drug dose should be prescribed is not related to ED50, which is about effectiveness, not dosing. D: Half of the drug is eliminated is not the definition of ED50, as it pertains to the dose-response relationship, not elimination.
Question 5 of 5
What is a treatment option for patient who reported small, vascular lesions on his genitals that lasted between 10 and 20 days?
Correct Answer: D
Rationale: The correct answer is D: Acyclovir (Zovirax). The patient's symptoms of small, vascular lesions on the genitals lasting 10-20 days are indicative of a viral infection, likely herpes simplex virus. Acyclovir is an antiviral medication commonly used to treat herpes infections. It works by inhibiting the replication of the virus, reducing the duration and severity of symptoms. Test of cure (A) is not appropriate in this case as the diagnosis is already evident. Three injections of penicillin (B) are used for bacterial infections, not viral. One-time dose of azithromycin (C) is used for bacterial infections like chlamydia or gonorrhea, not viral lesions.
