Nursing Elites

1. In conducting a community health fair for a group of middle-aged citizens, which statement should the nurse emphasize in reducing the risk of coronary heart disease?

• A. Participate in at least 30 minutes of moderate physical activity 3 to 5 days per week.
• B. Engage in an aerobic exercise class every day.
• C. Limit your alcohol intake to a moderate level.
• D. The best way to lose weight is to follow a balanced diet.

Correct answer: B

Rationale: Engaging in an aerobic exercise class every day is crucial in reducing the risk of coronary heart disease. Aerobic exercises help keep the heart in shape, lower blood pressure, and improve cholesterol levels. It is recommended to participate in at least 150 minutes of moderate-intensity aerobic exercise per week, which can be achieved by engaging in aerobic exercise daily. Choice A has been corrected to emphasize the frequency required to significantly reduce the risk of coronary heart disease. Choice C has been modified to suggest moderation in alcohol intake, as excessive alcohol consumption is harmful. Choice D is also incorrect as a balanced diet, not specifically high-protein, high-fat, is recommended to reduce the risk of coronary heart disease and maintain a healthy weight.

2. What happens if folic acid is administered to treat anemia without determining its underlying cause?

• A. Erythropoiesis is inhibited
• B. Excessive levels of folic acid might accumulate, causing toxicity
• C. The symptoms of pernicious anemia might be masked, delaying treatment
• D. Intrinsic factor is destroyed

Correct answer: C

Rationale: When folic acid is given without determining the underlying cause of anemia, the symptoms of pernicious anemia may be masked, potentially delaying the correct treatment. Folic acid alone does not protect against the central nervous system changes seen in pernicious anemia, which are related to Vitamin B12 deficiency. Folic acid and Vitamin B12 are both crucial for cell growth and division. Administering folic acid without knowing the specific type of anemia could lead to a delay in addressing the root cause. Option A is incorrect because folic acid is essential for erythropoiesis, the production of red blood cells. Option B is incorrect as excessive folic acid can cause toxicity, but it is not the primary concern in this context. Option D is incorrect because folic acid treatment for anemia does not directly impact intrinsic factor, which is related to Vitamin B12 absorption.

3. Why must the nurse be careful not to cut through or disrupt any tears, holes, bloodstains, or dirt present on the clothing of a client who has experienced trauma?

• A. The clothing is the property of another and must be treated with care.
• B. Such care facilitates repair and salvage of the clothing.
• C. The clothing of a trauma victim is potential evidence with legal implications.
• D. Such care decreases trauma to the family members receiving the clothing.

Correct answer: C

Rationale: The correct answer is C. Trauma in any client, living or dead, has potential legal and/or forensic implications. Clothing, patterns of stains, and debris are sources of potential evidence and must be preserved. Nurses must be aware of state and local regulations that require mandatory reporting of cases of suspected child and elder abuse, accidental death, and suicide. Each Emergency Department has written policies and procedures to assist nurses and other health care providers in making appropriate reports. Physical evidence is real, tangible, or latent matter that can be visualized, measured, or analyzed. Emergency Department nurses can be called on to collect evidence. Health care facilities have policies governing the collection of forensic evidence. The chain of evidence custody must be followed to ensure the integrity and credibility of the evidence. The chain of evidence custody is the pathway that evidence follows from the time it is collected until it has served its purpose in the legal investigation of an incident. Choices A, B, and D are incorrect because they do not address the crucial aspect of preserving potential evidence with legal implications that may be present on the clothing of a trauma victim.

4. One drug can alter the absorption of another drug. One drug increases intestinal motility. Which effect does this have on the second drug?

• A. None; absorption of the second drug is not affected.
• B. The increased gut motility decreases the absorption of the second drug.
• C. The absorption of the second drug cannot be predicted.
• D. Less of the second drug is absorbed.

Correct answer: D

Rationale: When one drug increases intestinal motility, it accelerates the movement of the second drug through the system. Since most oral medications are absorbed in the intestine, the faster transit time decreases the absorption of the second drug. Therefore, less of the second drug is absorbed. Choice A is incorrect because the increased gut motility does affect the absorption of the second drug. Choice C is incorrect as the effect of increased intestinal motility on drug absorption can be predicted based on pharmacokinetic principles. Choice B is incorrect as increased gut motility would not increase but decrease the absorption of the second drug.

5. Which deficiency in the mother has been primarily associated with neural tube defects in the fetus?

• A. Iron
• B. Folic acid
• C. Vitamin B12
• D. Vitamin E

Correct answer: B

Rationale: Folic acid deficiency in the mother has been primarily associated with neural tube defects in the fetus. Folic acid is crucial for the development of the neural tube in the early stages of pregnancy. Its deficiency can lead to neural tube defects, such as spina bifida or anencephaly. Iron deficiency is not directly related to neural tube defects but can cause other complications in pregnancy. Vitamin B12 is important for neurological function but is not the primary cause of neural tube defects. Vitamin E deficiency is not associated with neural tube defects in the fetus.
