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. What is most important for the healthcare professional to do prior to initiating peritoneal dialysis?

• A. Aspirate to check placement
• B. Ensure the client voids
• C. Irrigate the catheter to maintain patency
• D. Warm the fluids

Correct answer: D

Rationale: The correct answer is to warm the fluids. Warming the dialysis fluids is crucial before initiating peritoneal dialysis to prevent abdominal discomfort and promote vasodilation, which helps in achieving good exchange in the peritoneum. Aspirating to check placement (Choice A) is not typically necessary before initiating peritoneal dialysis. Ensuring the client voids (Choice B) is not directly related to the procedure of peritoneal dialysis. Irrigating the catheter to maintain patency (Choice C) is usually done as part of routine care but is not specifically required prior to initiating peritoneal dialysis. Therefore, the most important action to take before starting peritoneal dialysis is to warm the fluids.

3. What is the most common cause of acute renal failure?

• A. Shock
• B. Nephrotoxic drugs
• C. Enlarged prostate
• D. Diabetes

Correct answer: A

Rationale: The correct answer is 'Shock.' Acute renal failure is commonly caused by inadequate blood flow to the kidneys, which can occur in cases of shock. This leads to decreased kidney function and potential kidney damage. While nephrotoxic drugs can also cause acute renal failure, shock is the primary and most common cause. An enlarged prostate may lead to obstructive uropathy but is not the most prevalent cause of acute renal failure. Diabetes is typically associated with chronic kidney disease rather than acute renal failure.

4. For which adverse effect of the block does the postpartum nurse monitor the woman after receiving a subarachnoid (spinal) block for a cesarean delivery?

• A. Headache
• B. Pruritus
• C. Vomiting
• D. Hypertension

Correct answer: A

Rationale: The correct answer is 'Headache.' Postdural headache is a common adverse effect associated with a subarachnoid block due to cerebrospinal fluid leakage at the site of dural puncture. This headache worsens when the woman is upright and may improve when she lies flat. To manage this headache, bed rest and adequate hydration are recommended. Pruritus, vomiting, and hypertension are not typically associated with subarachnoid blocks. Pruritus, nausea, and vomiting are more commonly linked to the use of intrathecal opioids.

5. 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.
