Which side effect of the oral contraceptive subsides after 3-4 cycles of continued use

Correct Answer: C

Rationale: The correct answer is C) Headache. Rationale: Oral contraceptives can initially cause headaches as a side effect due to hormonal changes. However, after 3-4 cycles of continued use, the body typically adjusts to the hormones in the contraceptive, and the headaches subside. This is a common phenomenon seen with many side effects of oral contraceptives. Why the other options are wrong: A) Glucose intolerance is not a common side effect of oral contraceptives and does not typically subside with continued use. B) Rise in blood pressure can be a side effect of oral contraceptives but does not necessarily subside after 3-4 cycles; it may require a change in medication. D) Fluid retention can be a side effect of oral contraceptives, but like blood pressure, it may not necessarily subside after a few cycles and may require intervention. Educational context: Understanding the side effects of medications, especially oral contraceptives, is crucial for healthcare professionals. By knowing which side effects are common, temporary, or may require intervention, healthcare providers can better educate patients on what to expect and when to seek further medical advice. This knowledge is essential for nursing students preparing for the NCLEX exam to ensure safe and effective patient care.

Correct Answer: B

Rationale: In the context of postpartum hemorrhage, the drug of choice for controlling bleeding is Methylergometrine (Option B). Methylergometrine is an ergot alkaloid that acts on smooth muscle in the uterus, leading to vasoconstriction and uterine contraction, thereby reducing bleeding after childbirth. Option A, Oxytocin, is commonly used to induce or augment labor by stimulating uterine contractions but is not as effective in controlling postpartum hemorrhage as Methylergometrine. Option C, Dihydroergotamine, is primarily used to treat migraines and is not the drug of choice for postpartum hemorrhage. Option D, Prostaglandin E2, may be used in cases of postpartum hemorrhage refractory to other treatments, but it is not the first-line drug for this condition. Educationally, it is crucial for healthcare providers to understand the appropriate pharmacological interventions for postpartum hemorrhage to provide optimal care for postpartum women. Understanding the mechanisms of action and specific indications for each drug is essential in ensuring safe and effective management of postpartum hemorrhage, a potentially life-threatening complication of childbirth.

Correct Answer: C

Rationale: In the treatment of hypoparathyroidism, the drug of choice is Vitamin D (Option C). This is because hypoparathyroidism is characterized by low levels of parathyroid hormone, leading to decreased calcium levels in the blood. Vitamin D helps in the absorption of calcium from the gut and its reabsorption from the kidneys, thus aiding in raising and maintaining the calcium levels in the body. Option A, Parathormone, is the actual hormone that is deficient in hypoparathyroidism. However, due to its short half-life and the challenges associated with its administration, Vitamin D is preferred for long-term management. Option B, Calcium lactate, is a calcium supplement that can be used to raise calcium levels in the body, but it does not address the underlying cause of hypoparathyroidism. Option D, Pamidronate, is a bisphosphonate drug used to treat conditions of high calcium levels, such as hypercalcemia, and is not indicated for hypoparathyroidism. In an educational context, understanding the appropriate pharmacological management of endocrine disorders like hypoparathyroidism is crucial for nurses, pharmacists, and other healthcare professionals. By knowing the mechanism of action and rationale behind the choice of Vitamin D in this scenario, healthcare providers can make informed decisions to optimize patient care and outcomes.

Correct Answer: A

Rationale: Estrogens are steroid hormones responsible for various physiological functions in the body, including maintaining bone health. Option A, "Block bone resorption," is the correct answer because estrogens help to inhibit bone breakdown by osteoclasts, thus preserving bone density and strength. This action is crucial in preventing conditions like osteoporosis. Option B, "Maintain negative calcium balance," is incorrect. Estrogens actually help maintain a positive calcium balance by promoting calcium absorption in the intestines, reducing renal calcium excretion, and enhancing calcium deposition in bones. Option C, "Decrease HDL levels," is also incorrect. Estrogens are known to increase HDL (high-density lipoprotein) levels, which is considered beneficial for heart health as HDL helps to remove excess cholesterol from the bloodstream. Option D, "Increase bile acid secretion," is not a direct effect of estrogens. Estrogens do influence cholesterol metabolism and may impact bile composition, but they do not directly increase bile acid secretion. In an educational context, understanding the pharmacological effects of estrogens is essential for healthcare professionals, especially when managing conditions like hormonal imbalances, menopausal symptoms, or osteoporosis. Knowing the correct actions of estrogens can guide appropriate prescribing practices and patient education regarding potential side effects and benefits.

Correct Answer: A

Rationale: In this question on endocrine pharmacology, the correct answer is A) Mesterolone. Mesterolone is a synthetic androgen and anabolic steroid that is used to treat low testosterone levels in men. It is not associated with feminization because it does not have estrogenic effects. This is why feminization is not a side effect of mesterolone. The other options (B) Testosterone cypionate, (C) Testosterone, and (D) Testosterone propionate are forms of testosterone, a naturally occurring hormone in the body. Testosterone can be converted into estrogen in the body through a process called aromatization. When testosterone is converted into estrogen, it can lead to feminizing effects such as gynecomastia (breast enlargement in males) and other feminizing characteristics. This is why these forms of testosterone can potentially cause feminization as a side effect. From an educational standpoint, understanding the side effects of different hormonal medications is crucial for healthcare professionals, especially when prescribing or administering these medications to patients. This knowledge helps in assessing and managing potential adverse effects and ensuring safe and effective treatment outcomes for patients with endocrine disorders.
