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. When teaching a patient with COPD pulmonary exercises, what should be done?

• A. Teach pursed-lip breathing techniques.
• B. Encourage repetitive heavy lifting exercises to increase strength.
• C. Limit exercises due to respiratory acidosis.
• D. Take breaks every 10-20 minutes during exercises.

Correct answer: A

Rationale: The correct answer is to teach pursed-lip breathing techniques. Pursed-lip breathing helps to decrease the volume of air expelled by keeping the airways open longer, making it easier for patients with COPD to breathe out. Encouraging heavy lifting exercises (Choice B) is not suitable for patients with COPD as it can lead to increased shortness of breath. Limiting exercises due to respiratory acidosis (Choice C) is not correct; instead, exercises should be tailored to the patient's tolerance. Taking breaks every 10-20 minutes (Choice D) is not specific to the management of COPD pulmonary exercises.

3. When discussing the child's wishes for future care, it is important for the nurse to first identify what the child knows about the disease and his prognosis. Factors such as the perceived severity of the illness will be significant in planning for end-of-life care. If the child does not understand the disease process or prognosis, the plan of care would not be effective or realistic. In addition, asking a child about desired interventions in the event of cardiac or respiratory arrest would not be an appropriate initial area of questioning. If the child does not understand the disease process, these questions may seem frightening or threatening. While exploring the child's belief about death would be important, it would not be the initial area of discussion and should be guided by the child rather than the nurse.

• A. What the child knows about the disease and his prognosis.
• B. How the child would like to handle the plan of care.
• C. What interventions the child would like in the event of cardiac or respiratory arrest.
• D. What the child believes about death.

Correct answer: A

Rationale: When discussing the child's wishes for future care, it is essential to first determine what the child understands about the disease and his prognosis. This information is crucial for planning appropriate end-of-life care. If the child lacks comprehension of the illness and its prognosis, any care plan discussed would be ineffective and unrealistic. Inquiring about desired interventions during cardiac or respiratory arrest is not the initial step, as it may cause distress if the child lacks understanding. While exploring the child's beliefs about death is significant, it should not be the primary focus initially and should be approached based on the child's readiness, not the nurse's agenda. Therefore, the correct first step is to assess what the child knows about the disease and his prognosis.

4. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?

• A. metoclopramide (Reglan)
• B. ondansetron (Zofran)
• C. hydroxyzine (Vistaril)
• D. prochlorperazine (Compazine)

Correct answer: B

Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.

5. In a client with asthma who develops respiratory acidosis, what should the nurse expect the client's serum potassium level to be?

• A. normal
• B. elevated
• C. low
• D. unrelated to the pH

Correct answer: B

Rationale: In respiratory acidosis, the serum potassium level is expected to be elevated. This occurs because potassium shifts from cells into the bloodstream as a compensatory mechanism to maintain acid-base balance. Choices A, C, and D are incorrect. A normal potassium level is not expected in respiratory acidosis. A low potassium level is more commonly associated with alkalosis, not acidosis. The potassium level is indeed related to pH changes in respiratory acidosis, leading to the expected elevation.
