During prenatal development, a particular organ or body part is most vulnerable to exposure to teratogens during the: a) critical period. b) vulnerability period. c) period of viability. d) period of the fetus.

Answers

Answer 1

Answer:

a) Critical period.

Explanation:

During the critical period, exposure to teratogens such as alcohol, medications, X rays, etc can affect an organ or body parts that are developing at a certain time during pregnancy. As the organs and body parts develop at different times of the pregnancy, there are different critical periods. Once that part of the body is developed, the risk of being affected by a teratogen is very low.

Answer 2

Final answer:

During prenatal development, the period when an organ or body part is most vulnerable to teratogens is the critical period, which is a specific development stage where organs are forming. Exposure to harmful substances during this time can lead to significant malformations, making prenatal care essential for preventing teratogen-caused birth defects.

Explanation:

During prenatal development, a particular organ or body part is most vulnerable to teratogens during the critical period. This is the specific time frame when each organ or part of the fetus is developing and is most susceptible to the potential damage caused by teratogens such as drugs, alcohol, and some maternal diseases. For instance, the critical period for the development of the ears and arms is around six weeks after conception. If exposure to harmful substances occurs during this sensitive time, there's a higher chance of significant malformations.

Furthermore, the amount of exposure to teratogens is pivotal—substances may not be harmful unless exposure reaches a certain level. Plus, genetics play a crucial role as well, both in terms of the fetus's genetic makeup and the mother's, which can influence the degree of resistance to teratogenic effects.

Taking the potential for major morphological abnormalities into account, it's clear that quality prenatal care is crucial for minimizing risks. Teratogen-caused birth defects during critical periods are, in some cases, preventable with the correct awareness and healthcare measures.

Final answer:

When discharging a client prescribed Enalapril Maleate (Vasotec) for hypertension, the nurse must educate them on medication adherence, monitoring for side effects, the importance of follow-up, diet considerations including potassium levels, and appropriate aspirin therapy.

Explanation:

Enalapril Maleate (Vasotec) is an ACE inhibitor medication prescribed for blood pressure control. In educating a client for discharge, it's important to address medication adherence, potential side effects, and lifestyle modifications. Instructions should include taking the medication as prescribed, being aware of common side effects like cough or dizziness, and understanding the importance of follow-up appointments.

Advising on the need for a potassium-rich diet or potassium supplements if also taking diuretics like furosemide, which can lower potassium levels, is also essential. Lastly, the client should be informed about the importance of appropriate aspirin therapy and whether it is right for them in conjunction with enalapril and other cardiovascular prophylactic measures.

Home environment considerations, like avoiding substances that can elevate blood pressure, should also be discussed. Nurses should prioritize clients who are at high risk of medication-related harm by arranging enhanced support, such as post-discharge contact or follow-up visits. Recognizing and reporting any changes in health status, such as unusual fatigue or side effects, is crucial for preventing adverse events.

Mr. Clark is prescribed 500 mg of acetaminophen TID and 30 ml of prednisone BID. Mr. Clark takes his first dose of both medications at 0800 hours. When would you administer the second dose of acetaminophen?

A. 0100 hours
B. 2200 hours
C. 1100 hours
D. 1600 hours

Answers

Final answer:

If Mr. Clark takes his first dose of acetaminophen at 0800 hours and it's to be given TID (three times a day), the second dose would typically be administered around 8 hours later, that is, 1600 hours.

Explanation:

The question asks when the second dose of acetaminophen would be given if Mr. Clark takes his first dose at 0800 hours and it's prescribed TID (three times a day). Prescriptions that require dosing three times a day are typically evenly distributed throughout waking hours. Therefore, this typically equates to approximately every 8 hours. If Mr. Clark takes his first dose at 0800 hours, the second dose of acetaminophen should be administered around 8 hours later which would be around 1600 hours. Hence, the answer is D. 1600 hours.
