1. When a healthcare professional observes muscle stiffening occurring within 6 to 14 hours after death, the healthcare professional should document this finding as _____ present.
- A. Livor mortis
- B. Gangrene
- C. Algor mortis
- D. Rigor mortis
Correct answer: D
Rationale: The correct answer is D, Rigor mortis. Rigor mortis is the stiffening of muscles after death, typically beginning within 6 to 14 hours. Livor mortis (choice A) refers to the pooling of blood in the lowest tissues causing discoloration, gangrene (choice B) is the death of body tissue due to lack of blood flow, and algor mortis (choice C) is the cooling of the body after death.
2. What causes atherosclerotic plaques to form in the body?
- A. Poor dietary habits
- B. Administration of statin medication
- C. Interruption of blood flow to the brain
- D. Injury to the endothelium of the coronary arteries
Correct answer: D
Rationale: Atherosclerotic plaques form in the body due to injury to the endothelium of the coronary arteries. When the endothelium is damaged, it triggers an inflammatory response that leads to the accumulation of fats, cholesterol, and other substances, forming plaques. These plaques can narrow the arteries, reducing blood flow and potentially leading to serious complications like heart attacks or strokes. Poor dietary habits (choice A) can contribute to the development of atherosclerosis by promoting the buildup of plaque-forming substances in the blood, but the direct cause is the injury to the endothelium. Administration of statin medication (choice B) is actually a treatment for high cholesterol and aims to reduce the risk of plaque formation. Interruption of blood flow to the brain (choice C) is more related to conditions like ischemic stroke rather than the primary cause of atherosclerotic plaque formation.
3. What adverse effect should the nurse monitor for during testosterone therapy in a male patient?
- A. Increased risk of cardiovascular events
- B. Increased risk of liver dysfunction
- C. Increased risk of prostate cancer
- D. Increased risk of bone fractures
Correct answer: A
Rationale: The correct answer is A: Increased risk of cardiovascular events. Testosterone therapy can lead to an increased risk of cardiovascular events, such as heart attacks and strokes. This is why nurses should monitor for signs and symptoms of cardiovascular issues during therapy. Choices B, C, and D are incorrect because testosterone therapy is not typically associated with an increased risk of liver dysfunction, prostate cancer, or bone fractures. It is crucial for nurses to prioritize cardiovascular monitoring in patients receiving testosterone therapy.
4. As you are walking in the park, a huge black Labrador runs up to you and places his paws on your shoulders. Immediately your heart starts racing, you feel palpitations, anxiety, and your hands become a little shaky. The nurse knows that this response is primarily caused by:
- A. cerebral cortex.
- B. somatic nervous system.
- C. limbic system.
- D. autonomic nervous system.
Correct answer: D
Rationale: The autonomic nervous system controls involuntary bodily functions like heart rate, respiration, and sweating. In the given scenario, the 'fight or flight' response is activated, leading to increased heart rate, palpitations, anxiety, and shaky hands. The cerebral cortex is involved in conscious thought processes and decision-making, not the immediate physiological response observed here. The somatic nervous system regulates voluntary movements, while the limbic system is responsible for emotions and memory, but the autonomic nervous system is primarily responsible for the physiological responses seen in this situation.
5. A patient is prescribed acyclovir (Zovirax) for the treatment of genital herpes. What is the expected outcome of this medication?
- A. Decreased testosterone production
- B. Decreased libido
- C. Decreased viral shedding
- D. Decreased bacterial replication
Correct answer: C
Rationale: The expected outcome of acyclovir (Zovirax) for the treatment of genital herpes is decreased viral shedding. Acyclovir is an antiviral medication that works by inhibiting the replication of the herpes virus, thereby reducing viral shedding and helping to control outbreaks. Choice A, decreased testosterone production, and Choice B, decreased libido, are unrelated outcomes of acyclovir treatment for genital herpes. Choice D, decreased bacterial replication, is also incorrect as acyclovir specifically targets viruses and does not affect bacterial replication.
