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. A client asks a nurse working in a dental office what type of drug the dentist uses to provide anesthesia during the extraction of the client's wisdom teeth. The dentist uses an anesthetic gas, also known as laughing gas. This agent is:
- A. nitrous oxide.
- B. nitrogen.
- C. nitric oxide.
- D. nitrogen dioxide.
Correct answer: A
Rationale: The correct answer is nitrous oxide. Nitrous oxide is commonly known as laughing gas and is used as an anesthetic gas for procedures like dental extractions. It produces analgesia and mild euphoria without loss of consciousness. Nitrogen is a nonmetallic element found in air, while nitric oxide is a vasodilator produced from L-arginine. Nitrogen dioxide is a poisonous gas found in smog and exhaust fumes and is not used for anesthesia.
3. A patient has just been prescribed Minipress to control hypertension. The nurse should instruct the patient to be observant of the following:
- A. Dizziness and light-headed sensations
- B. Weight gain
- C. Sensory changes in the lower extremities
- D. Fatigue
Correct answer: A
Rationale: The correct answer is 'Dizziness and light-headed sensations.' Minipress, a medication used to control hypertension, can cause hypotension as a side effect. Dizziness and light-headed sensations are common symptoms of hypotension. Weight gain, sensory changes in the lower extremities, and fatigue are not typically associated with Minipress or hypertension management. Therefore, they are incorrect choices.
4. A pregnant Asian client who is experiencing morning sickness wants to take ginger to relieve the nausea. Which of the following responses by the nurse is appropriate?
- A. "I will call your physician to see if we can start some ginger."?
- B. "We don't use home remedies in this clinic."?
- C. "Herbs are not as effective as regular medicines."?
- D. "Just eat some dry crackers instead."?
Correct answer: A
Rationale: The correct response is appropriate as it demonstrates cultural sensitivity. Ginger is commonly used to alleviate nausea, particularly in Asian cultures. Contacting the physician to discuss the use of ginger ensures the client's safety and respects their preferences. Choices B and C are incorrect as they disregard the client's request and fail to acknowledge their cultural beliefs. Choice D is incorrect because it does not address the client's desire to use ginger for relief.
5. 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.
