1. A patient with osteoporosis is prescribed raloxifene (Evista). What is the primary therapeutic action of this medication?

Correct answer: A

Rationale: The correct answer is A. Raloxifene works by decreasing bone resorption and increasing bone density. This helps in preventing further bone loss and reducing the risk of fractures in patients with osteoporosis. Choice B is incorrect because raloxifene does not stimulate the formation of new bone, but rather helps to maintain existing bone mass. Choice C is incorrect as raloxifene does not directly increase calcium absorption in the intestines. Choice D is also incorrect as raloxifene does not increase the excretion of calcium through the kidneys.

2. A patient has been prescribed clomiphene citrate (Clomid) for infertility. What should the nurse include in the teaching plan about the use of this medication?

Correct answer: A

Rationale: Corrected Rationale: Clomiphene is typically taken daily for 5 days at the beginning of the menstrual cycle to stimulate ovulation. Choice A is the correct answer because it aligns with the standard dosing regimen for clomiphene citrate. Choices B, C, and D provide incorrect information about the dosing schedule for clomiphene, which can lead to ineffective treatment and potential side effects. Choice B suggests continuous daily intake, which is not the standard practice for clomiphene. Choice C and D mention different dosing frequencies and timings, which are not in line with the typical protocol for using clomiphene for infertility.

3. A woman has been prescribed Climara, a transdermal estradiol patch. Which of the following should she be instructed by the nurse regarding the administration?

Correct answer: A

Rationale: The correct answer is A. The Climara patch delivers estradiol transdermally, and patients should be instructed to avoid prolonged sun exposure at the patch site due to increased plasma concentrations. Sun exposure can accelerate the absorption of the medication, leading to higher systemic levels than intended. Choices B, C, and D are incorrect because heat at the patch site does not result in pregnancy but may alter absorption rates, there is no direct link between sunlight exposure and breast cancer risk related to this medication, and exposure to cold does not increase effectiveness of the transdermal patch.

4. When the body produces antibodies against its own tissue, the condition is called:

Correct answer: C

Rationale: Autoimmunity is the correct term for a condition where the body's immune system mistakenly targets its own tissues. Alloimmunity (Choice A) refers to an immune response against foreign tissue. Opsonization (Choice B) is a process where pathogens are marked for destruction by immune cells. Hypersensitivity (Choice D) involves an exaggerated immune response against antigens.

5. What function does aldosterone serve in the body?

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.
