ATI Pathophysiology Exam 2
1. A woman suffers from amenorrhea. Which of the following medications will most likely be prescribed?
- A. Testosterone
- B. Follicle-stimulating hormone
- C. Estrogen
- D. Lactate
Correct answer: C
Rationale: Estrogen is the correct answer. Amenorrhea, the absence of menstruation, is often due to hormonal imbalances. Estrogen plays a crucial role in regulating the menstrual cycle. Prescribing estrogen can help address these hormonal imbalances and restore menstrual cycles. Testosterone (Choice A) is not typically prescribed for amenorrhea in women as it can further disrupt hormonal balance. Follicle-stimulating hormone (Choice B) is involved in stimulating ovulation and follicle development, not the primary treatment for amenorrhea. Lactate (Choice D) is not a medication used to treat amenorrhea.
2. Which condition is characterized by a lack of antidiuretic hormone (ADH)?
- A. Diabetes mellitus
- B. Diabetes insipidus
- C. Cushing's disease
- D. Hyperthyroidism
Correct answer: B
Rationale: The correct answer is B, Diabetes insipidus. Diabetes insipidus is characterized by a lack of antidiuretic hormone (ADH), leading to excessive urination and thirst. Choice A, Diabetes mellitus, is a different condition characterized by high blood sugar levels. Choice C, Cushing's disease, is caused by prolonged exposure to high levels of cortisol. Choice D, Hyperthyroidism, involves an overactive thyroid gland producing excess thyroid hormones.
3. What function does aldosterone serve in the body?
- A. Aldosterone causes a release of sodium from the body, decreases fluid volume, and decreases blood pressure
- B. Aldosterone causes a retention of sodium in the body, increases fluid volume, and increases blood pressure
- C. Aldosterone causes a release of sodium from the body, increases fluid volume, and decreases blood pressure
- D. Aldosterone enhances intracellular sodium production and lowers blood pressure
Correct answer: B
Rationale: Aldosterone functions by causing the retention of sodium in the body, which results in an increase in fluid volume and blood pressure. Choice A is incorrect because aldosterone actually promotes sodium retention rather than release. Choice C is incorrect as it states that aldosterone decreases fluid volume, which is not accurate. Choice D is incorrect because aldosterone does not enhance intracellular sodium production; instead, it primarily acts on sodium reabsorption in the kidneys.
4. A patient with a history of osteoporosis is prescribed alendronate (Fosamax). What instructions should the nurse provide to ensure the effectiveness of the medication?
- A. Take the medication with a full glass of water and remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption.
- B. Take the medication with milk to enhance calcium absorption.
- C. Take the medication at bedtime to ensure absorption during sleep.
- D. Take the medication with food to prevent nausea.
Correct answer: A
Rationale: The correct answer is A. Alendronate should be taken with a full glass of water and patients should remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption. Taking the medication with milk (choice B) is not recommended as it may interfere with the absorption of alendronate. Taking the medication at bedtime (choice C) is not necessary for optimal absorption. Taking the medication with food (choice D) is also not recommended as food can reduce the absorption of alendronate.
5. When arterial blood pressure declines, the kidneys secrete a hormone to increase blood pressure and peripheral resistance. What is this hormone called?
- A. Renin
- B. Antidiuretic hormone
- C. Atrial natriuretic
- D. Insulin
Correct answer: A
Rationale: Renin is the correct answer. When arterial blood pressure decreases, the kidneys release renin, which triggers a series of reactions ultimately leading to an increase in blood pressure and peripheral resistance. Antidiuretic hormone (choice B) is involved in water retention, atrial natriuretic hormone (choice C) promotes sodium excretion and lowers blood pressure, and insulin (choice D) regulates glucose metabolism, not blood pressure.
