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.

A client is admitted to the critical care unit after suffering from a massive cerebral vascular accident. The client's vital signs include BP 160/110, HR 42, Cheyne-Stokes respirations. Based on this assessment, the nurse anticipates the client to be in which acid-base balance?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct Answer: A
Rationale: In this scenario, the client is exhibiting Cheyne-Stokes respirations, which are characterized by periods of deep breathing alternating with apnea. This pattern indicates respiratory insufficiency, resulting in an accumulation of carbon dioxide in the blood. The elevated BP and slow heart rate further support the respiratory insufficiency, leading to respiratory acidosis. Therefore, the correct answer is Respiratory acidosis.
Choices B, C, and D are incorrect. Respiratory alkalosis is characterized by decreased carbon dioxide levels in the blood, which is not indicated by the client's presentation. Metabolic acidosis results from conditions such as renal failure or diabetic ketoacidosis and is not the primary imbalance in this case. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels, which are not present in the client's vital signs.
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.
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.
The client is wheezing and struggling to breathe. Which of the inhaled medications is indicated at this time?
- A. Fluticasone (Flovent)
- B. Salmeterol (Serevent)
- C. Theophylline (Theodur)
- D. Albuterol (Atrovent)
Correct Answer: D
Rationale: The correct answer is Albuterol (Atrovent) because it is a rapid-acting bronchodilator, essential for a client experiencing wheezing and difficulty breathing. Albuterol acts quickly, dilating the airways and providing immediate relief in cases of respiratory distress. Fluticasone (Flovent) and Salmeterol (Serevent) are maintenance medications for long-term asthma control, not suitable for acute situations described. Theophylline (Theodur) is a bronchodilator but with a slower onset compared to Albuterol, making it less appropriate for a client in immediate distress.
When dressing a severe burn to the right hand, it is important for the nurse to:
- A. Apply a wet-to-dry dressing for debridement
- B. Wrap each digit individually to prevent webbing
- C. Open blisters to allow drainage prior to dressing
- D. Allow the client to do as much of the dressing change as possible
Correct Answer: B
Rationale: When dressing a severe burn to the hand, it is crucial to wrap each digit individually to prevent webbing, which can lead to contractures and impaired function. Applying a wet-to-dry dressing for debridement is not recommended for burn wounds as it can cause trauma to the wound bed during removal. Opening blisters can increase the risk of infection and delay healing. Allowing the client to perform the dressing change may not ensure proper care and can lead to complications.
