Kaplan NCLEX Question of The Day
1. Which hormone is responsible for amenorrhea in the pregnant woman?
- A. Progesterone
- B. Estrogen
- C. Follicle-stimulating hormone (FSH)
- D. Human chorionic gonadotropin (hCG)
Correct answer: A
Rationale: Correct! Progesterone is the hormone responsible for amenorrhea in pregnant women. Progesterone plays a crucial role in maintaining the uterine lining for implantation and supporting early pregnancy. High levels of progesterone during pregnancy suppress the normal menstrual cycle, leading to amenorrhea. Estrogen, FSH, and hCG do not directly cause amenorrhea in pregnant women. Estrogen is involved in the development of female secondary sexual characteristics, FSH is involved in the growth and maturation of ovarian follicles, and hCG is produced by the placenta to support the production of progesterone during pregnancy.
2. One of the major functions of the kidneys in maintaining normal fluid balance is:
- A. the manufacture of antidiuretic hormone.
- B. the regulation of calcium and phosphate balance.
- C. the regulation of the pH of the extracellular fluid.
- D. the control of aldosterone levels.
Correct answer: C
Rationale: The correct answer is 'the regulation of the pH of the extracellular fluid.' The kidneys play a crucial role in maintaining normal fluid balance by regulating extracellular fluid and osmolarity through selective retention and excretion of fluids. Additionally, they regulate the pH of the extracellular fluid by retaining hydrogen ions and excreting metabolic wastes and toxic substances. Choice A is incorrect because antidiuretic hormone (ADH) is manufactured by the pituitary gland, not the kidneys. Choice B is incorrect as the regulation of calcium and phosphate balance is primarily controlled by the parathyroid gland. Choice D is incorrect as aldosterone levels are controlled by the adrenal glands, not the kidneys.
3. Which dietary consideration is most important for the nurse to teach to a client with hypothyroidism?
- A. Increase carbohydrate intake
- B. Increase fluid intake
- C. Avoid shellfish
- D. Increase fiber
Correct answer: D
Rationale: The correct answer is to 'Increase fiber.' In hypothyroidism, clients often experience constipation due to decreased metabolic rate. Increasing fiber in the diet can help alleviate constipation. Choice A, 'Increase carbohydrate intake,' is incorrect as there is no specific need to increase carbohydrate intake in hypothyroidism. Choice B, 'Increase fluid intake,' is not directly related to managing hypothyroidism, although adequate hydration is generally important for overall health. Choice C, 'Avoid shellfish,' is commonly associated with hyperthyroidism due to its iodine content, not hypothyroidism.
4. The nurse is caring for a 44-year-old client diagnosed with hypoparathyroidism. Which electrolyte imbalance is closely associated with hypoparathyroidism?
- A. Hypocalcemia.
- B. Hyponatremia.
- C. Hyperkalemia.
- D. Hypophosphatemia.
Correct answer: A.
Rationale: The correct answer is Hypocalcemia. In hypoparathyroidism, where the parathyroid glands are not producing sufficient parathyroid hormone, calcium levels become inadequate. This leads to hypocalcemia, characterized by symptoms such as muscle spasms, anxiety, seizures, hypotension, and congestive heart failure. Hyponatremia and hyperkalemia are not typically associated with hypoparathyroidism. While hyperphosphatemia can be seen in hypoparathyroidism due to decreasing calcium levels, the question specifically asks about the primary electrolyte imbalance closely related to hypoparathyroidism, which is hypocalcemia.
5. How can light therapy be effective?
- A. overcoming weight problems.
- B. helping with allergies.
- C. use in alternative medical treatments.
- D. working with sleep patterns.
Correct answer: D
Rationale: Light therapy can be effective in treating problems associated with sleep patterns, stress, moods, jaundice in newborns, and seasonal affective disorders. While light therapy is not typically used for overcoming weight problems or helping with allergies, it is specifically known for its benefits in regulating sleep patterns. Therefore, the correct answer is 'working with sleep patterns.' Choices A, B, and C are incorrect as light therapy is not commonly utilized for overcoming weight problems, helping with allergies, or as a general alternative medical treatment.
