1. In which patient is alpha-1 antitrypsin deficiency the likely cause of chronic obstructive pulmonary disease?

• A. A 30-year-old who has smoked for 3 years
• B. A 65-year-old man who worked as a taxi driver most of his life
• C. A 70-year-old woman who smoked for 40 years
• D. A 50-year-old with exposure to secondhand smoke

Correct answer: A

Rationale: The correct answer is A. Alpha-1 antitrypsin deficiency is a genetic condition that can lead to COPD at a young age, even in light smokers. Choice B is less likely as the patient's occupation does not directly correlate with alpha-1 antitrypsin deficiency. Choice C, a 70-year-old woman with a long smoking history, is more likely to have COPD due to smoking rather than alpha-1 antitrypsin deficiency. Choice D, exposure to secondhand smoke, is not a common cause of alpha-1 antitrypsin deficiency-related COPD.

2. A 23-year-old pregnant female visits her primary care provider for her final prenatal checkup. The primary care provider determines that the fetus has developed an infection in utero. Which of the following would be increased in the fetus at birth?

• A. IgG
• B. IgA
• C. IgM
• D. IgD

Correct answer: C

Rationale: The correct answer is IgM. IgM is the first antibody produced in response to an infection and is elevated in a fetus with an in utero infection. IgG is the primary antibody responsible for providing immunity to the fetus and is transferred across the placenta during the third trimester. IgA is mainly found in mucosal areas and colostrum but not significantly elevated in fetal infections. IgD is involved in the development and maturation of B cells but not typically increased in fetal infections.

3. What is a characteristic of coronary artery disease (CAD)?

• A. The build-up of infectious by-products in the lymph nodes
• B. Insufficient delivery of oxygenated blood to the myocardium
• C. Insufficient delivery of carbon dioxide to the lungs
• D. The build-up of bile in the stomach and gallbladder

Correct answer: B

Rationale: The correct characteristic of coronary artery disease (CAD) is the insufficient delivery of oxygenated blood to the myocardium. CAD is a condition where the coronary arteries become narrowed or blocked, leading to reduced blood flow to the heart muscle. This lack of oxygenated blood can result in chest pain, known as angina, and if a coronary artery becomes completely blocked, it can cause a heart attack. Choices A, C, and D are incorrect. Choice A refers to an issue related to the lymphatic system, choice C is about gas exchange in the lungs, and choice D describes a problem with bile accumulation in the digestive system, none of which are characteristics of CAD.

4. In chronic obstructive pulmonary disease, the inflammatory response predominantly involves:

• A. eosinophils
• B. neutrophils
• C. monocytes
• D. cells

Correct answer: B

Rationale: In chronic obstructive pulmonary disease, the inflammatory response predominantly involves neutrophils. Neutrophils play a key role in COPD due to their involvement in initiating and sustaining the inflammatory process. Eosinophils are more commonly associated with asthma rather than COPD. Monocytes are less involved in the inflammatory response in COPD compared to neutrophils. The choice 'cells' is too broad and vague to be a specific answer in this context.

5. When preparing to administer parenteral acyclovir (Zovirax) to an 80-year-old patient with chronic renal failure and herpes simplex, what would the nurse expect in regard to the dose?

• A. The dose is smaller due to the herpes simplex infection.
• B. The dose is smaller based on the patient's kidney function.
• C. The dose is higher in treating genital herpes.
• D. The dose is higher if the creatinine clearance is above 4.0 mg/dL.

Correct answer: B

Rationale: In patients with chronic renal failure, especially in older adults, dosages of medications excreted renally need to be adjusted based on kidney function. Acyclovir is primarily eliminated by the kidneys, so in a patient with chronic renal failure, the dose would need to be smaller to prevent drug accumulation and toxicity. Choice A is incorrect because the dose adjustment is more related to the patient's kidney function than the presence of herpes simplex. Choice C is incorrect because the type of herpes infection does not determine the dose adjustment for acyclovir. Choice D is incorrect as the creatinine clearance is a more accurate measure of kidney function compared to creatinine levels.
