Question 1 of 5
Which factor causes women to experience more problems than men when taking aspirin?
Correct Answer: A
Rationale: The correct answer is A: Gastric acidity. Women tend to have higher gastric acidity than men, leading to increased risk of gastrointestinal issues when taking aspirin. Higher acidity can cause irritation and ulceration in the stomach lining. Levels of hepatic enzyme (
B) and amounts of alcohol dehydrogenase (
C) are not directly linked to aspirin-related issues. Decreased gastric emptying (
D) can also contribute to aspirin-related problems but is not the primary factor.
Question 2 of 5
Which range of the normal adult dose, with the amount of medication increasing over time, is used when initiating drug therapy in elderly adults?
Correct Answer: D
Rationale: The correct answer is D: One-third to one-half. When initiating drug therapy in elderly adults, it is important to start with lower doses and gradually increase to minimize the risk of adverse effects. Choosing a dose range of one-third to one-half of the normal adult dose allows for a conservative approach to medication initiation in this population. Option A (One-eighth to one-fourth) and B (One-fourth to one-third) are too conservative and may result in subtherapeutic doses. Option C (One-half to three-fourths) is too aggressive and may increase the risk of adverse effects in elderly adults.
Therefore, the correct choice is D as it balances the need for efficacy with safety when starting drug therapy in the elderly.
Question 3 of 5
Which drugs cause birth defects?
Correct Answer: D
Rationale: The correct answer is D: Teratogens. Teratogens are substances that can interfere with normal prenatal development and cause birth defects. They include drugs such as alcohol, certain medications, and chemicals. Placebo (
A) is an inert substance with no pharmacological effect. Carcinogens (
B) are substances that can cause cancer, not birth defects. Steroids (
C) are medications that can have side effects but are not primarily known for causing birth defects. In summary, teratogens specifically refer to substances that can lead to birth defects, while the other choices do not have this direct impact on prenatal development.
Question 4 of 5
Which statement about a clinical care pathway is true?
Correct Answer: D
Rationale: The correct answer is D because a clinical care pathway is a standardized care plan based on best practices. It guides healthcare professionals in delivering consistent, evidence-based care to patients. This ensures quality, efficiency, and patient safety. Option A is incorrect as a clinical care pathway is not specifically for critical conditions but can be used in various healthcare settings. Option B is incorrect as it is not solely a communication tool for nurses but for interdisciplinary teams. Option C is incorrect as a clinical care pathway outlines the entire patient journey, not just admission.
Question 5 of 5
A patient is receiving medication to increase urine output. The patient's urinary output increases significantly and the blood pressure decreases slightly. Which type of side effect is a decrease in blood pressure?
Correct Answer: A
Rationale: The correct answer is A: Common. When a patient is receiving medication to increase urine output, a decrease in blood pressure is a common side effect. This is because increasing urine output can lead to fluid loss, resulting in a decrease in blood volume and subsequently blood pressure. It is common for diuretics, which increase urine output, to cause a slight decrease in blood pressure as a side effect. Other choices are incorrect because a decrease in blood pressure in this context is not necessarily desired (
B), therapeutic (
C), or any other specific type of side effect (D, E, F, G).
