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. Levothyroxine (Synthroid) is the drug of choice for thyroid replacement therapy in clients with hypothyroidism because:

• A. it is chemically stable, nonallergenic, and can be administered orally once a day.
• B. it is available in a wide range of concentrations to meet individual client requirements.
• C. it is a prodrug of T3.
• D. it has a long half-life.

Correct answer: A

Rationale: Levothyroxine (Synthroid) is the preferred medication for hypothyroidism due to its chemical stability, nonallergenic properties, and convenient once-daily oral administration. It is safe and effective with minimal side effects when appropriately dosed. Choice B is incorrect because while Levothyroxine is available in various concentrations, it is not the reason it is the drug of choice; the primary reason is its stability and nonallergenic nature. Choice C is wrong as Levothyroxine (T4) is not a prodrug of T3; it is converted to T3 in the body. Option D is inaccurate because Levothyroxine has a long half-life (around 7 days), enabling once-daily dosing, as opposed to a short half-life.

3. What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36 mmHg, and HCO3 24 mEq/L?

• A. metabolic alkalosis
• B. homeostasis
• C. respiratory acidosis
• D. respiratory alkalosis

Correct answer: B

Rationale: The correct answer is 'homeostasis.' These ABG values fall within the normal range, indicating a state of balance and homeostasis. The pH is within the normal range (7.35-7.45), the PCO2 is normal (35-45 mmHg), and the HCO3 level is also normal (22-26 mEq/L). Choice A, 'metabolic alkalosis,' is incorrect because the pH, PCO2, and HCO3 levels are not indicative of metabolic alkalosis. Choice C, 'respiratory acidosis,' is incorrect as the pH and PCO2 values are not elevated. Choice D, 'respiratory alkalosis,' is incorrect as the pH and PCO2 levels are not decreased. Therefore, the ABG values provided do not correspond to any acid-base disturbance, confirming that the patient is in a state of homeostasis.

4. A patient has been diagnosed with fibromyalgia and COPD. Which of the following tasks should the nurse delegate to a nursing assistant?

• A. Transferring the patient to the shower.
• B. Ambulating the patient for the first time.
• C. Taking the patient's breath sounds.
• D. Educating the patient on monitoring fatigue.

Correct answer: A

Rationale: The correct answer is to delegate the task of transferring the patient to the shower to a nursing assistant. Nursing assistants are trained to assist with transfers safely, making this task appropriate for delegation. Ambulating the patient for the first time involves assessing the patient's mobility and tolerance, which requires more assessment and monitoring by a nurse, especially in a patient with fibromyalgia and COPD. Taking the patient's breath sounds involves assessing the patient's respiratory status, which is a nursing responsibility due to the need for clinical judgment. Educating the patient on monitoring fatigue involves providing vital information and should be done by the nurse to ensure comprehensive understanding and tailored recommendations.

5. A client is admitted for observation following an unrestrained motor vehicle accident. A bystander stated that he lost consciousness for 1-2 minutes. On admission, the client's Glasgow Coma Scale (GCS) was 14. The GCS is now 12. The nurse should:

• A. Re-assess in 15 minutes
• B. Stimulate the client with a sternal rub
• C. Administer Tylenol with codeine for a headache
• D. Notify the physician

Correct answer: D

Rationale: A decrease in the Glasgow Coma Scale (GCS) score from 14 to 12 indicates a significant neurological change in the client's condition. This change can be indicative of a deterioration in the client's neurological status, possibly due to intracranial bleeding or swelling. It is crucial for the nurse to notify the physician immediately to ensure prompt evaluation and intervention. Re-assessing in 15 minutes or stimulating the client with a sternal rub are not appropriate actions in this situation as they do not address the underlying cause of the decrease in GCS. Administering Tylenol with codeine for a headache is also not recommended without further assessment and evaluation of the client's condition.
