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 begins a regimen of chemotherapy. Her platelet count falls to 98,000. Which action is least likely to increase the risk of hemorrhage?

• A. Test all excreta for occult blood.
• B. Use a soft toothbrush or foam cleaner for oral hygiene.
• C. Implement reverse isolation.
• D. Avoid IM injections.

Correct answer: C

Rationale: The correct answer is to implement reverse isolation. Reverse isolation is a protective measure used to protect patients from infections, not to affect the risk of hemorrhage. Testing all excreta for occult blood (Choice A) is important to monitor for signs of internal bleeding. Using a soft toothbrush or foam cleaner for oral hygiene (Choice B) is recommended to prevent gum bleeding. Avoiding IM injections (Choice D) is crucial to reduce the risk of bleeding in a client with a low platelet count. Therefore, among the given options, implementing reverse isolation is the least likely to increase the risk of hemorrhage.

3. A client complaining of chest pain is prescribed an intravenous infusion of nitroglycerin (Nitro-Bid). After the infusion is initiated, the occurrence of which symptom warrants the nurse discontinuing an intravenous infusion of nitroglycerin?

• A. Frontal headache
• B. Orthostatic hypotension
• C. Decrease in intensity of chest pain
• D. Cool clammy skin

Correct answer: D

Rationale: The correct answer is 'Cool clammy skin.' This assessment finding indicates decreased cardiac output that could result from excessive vasodilation. Cool clammy skin is a sign of poor perfusion, suggesting that the blood pressure might be dropping too low. Discontinuing the nitroglycerin infusion is crucial to prevent further complications. Choice A, 'Frontal headache,' is a common side effect of nitroglycerin but not a reason to discontinue the infusion unless severe or persistent. Choice B, 'Orthostatic hypotension,' may occur as a side effect of nitroglycerin but does not necessarily warrant discontinuation unless severe. Choice C, 'Decrease in intensity of chest pain,' is actually an expected therapeutic response to nitroglycerin and indicates improved myocardial perfusion, so it is not a reason to stop the infusion.

4. A patient has recently been prescribed Zidovudine (Retrovir). The patient has AIDS. Which of the following side effects should the patient specifically watch out for?

• A. Weakness and SOB
• B. Fever and anemia
• C. Hypertension and SOB
• D. Fever and hypertension

Correct answer: B

Rationale: The correct answer is 'Fever and anemia.' Zidovudine (Retrovir) is known to cause anemia as a side effect due to its impact on the bone marrow. Fever is also a common side effect associated with Zidovudine use. Therefore, the patient should watch out for these specific side effects. Choice A (Weakness and SOB) is incorrect as shortness of breath (SOB) is not a commonly reported side effect of Zidovudine. Choice C (Hypertension and SOB) and Choice D (Fever and hypertension) are unrelated to the known side effects of Zidovudine, making them incorrect.

5. A client has been diagnosed with Disseminated Intravascular Coagulation (DIC) and transferred to the medical intensive care unit (ICU) following an acute bleeding episode. In the ICU, continuous Heparin drip therapy is initiated. Which of the following assessment findings indicates a positive response to Heparin therapy?

• A. increased platelet count
• B. increased fibrinogen
• C. decreased fibrin split products
• D. decreased bleeding

Correct answer: B

Rationale: In the context of DIC, effective Heparin therapy aims to halt the process of intravascular coagulation. One of the indicators of a positive response to Heparin therapy is an increase in fibrinogen levels. Heparin interferes with the conversion of fibrinogen to fibrin by thrombin. This interruption helps increase the availability of fibrinogen. While the platelet count may increase due to improved clotting, the primary focus of Heparin therapy is on fibrinogen. Fibrin split products are expected to decrease as the coagulation cascade is controlled. Although decreased bleeding is an ultimate goal, the immediate effect of Heparin is not directly on bleeding but on the coagulation process.
