Biology Practice Test
1. Phagocytes in the immune system are responsible for the biological action of which of the following?
- A. Secreting
- B. Consuming
- C. Altering
- D. Building
Correct answer: B
Rationale: The correct answer is B: Consuming. Phagocytes are cells that engulf and digest pathogens, dead cells, and other harmful particles, playing a crucial role in the immune system's defense. Phagocytes do not secrete substances, alter particles, or build structures; their primary function is to consume and eliminate harmful entities.
2. While caring for a client's postoperative dressing, the nurse observes purulent drainage at the wound. Before reporting this finding to the healthcare provider, the nurse should review which of the client's laboratory values?
- A. White blood cell count
- B. Hemoglobin
- C. Serum creatinine
- D. Culture for sensitive organisms
Correct answer: D
Rationale: Purulent drainage suggests an infection at the wound site. Reviewing the culture and sensitivity results will guide appropriate antibiotic treatment by identifying the causative organisms and their antibiotic sensitivities. Elevated white blood cells indicate infection but do not specify the organism. Creatinine and hemoglobin values are unrelated to wound infections.
3. During a class on exercise for diabetic clients, a female client asks the nurse educator how often to exercise. The nurse educator advises the clients to exercise how often to meet the goals of planned exercise?
- A. At least once a week
- B. At least three times a week
- C. At least five times a week
- D. Every day
Correct answer: C
Rationale: Exercising at least five times a week is recommended to meet the goals of planned exercise for diabetic clients. This frequency helps in managing blood sugar levels effectively and improving overall health. Exercising once a week (Choice A) may not provide sufficient benefits or consistency required for diabetic clients. Exercising three times a week (Choice B) is better but may still fall short of the recommended frequency for optimal outcomes. Exercising every day (Choice D) may lead to burnout or overtraining if not properly balanced with rest days, which could be counterproductive for diabetic clients.
4. A 24-year-old female client who has a history of rheumatoid arthritis (RA) is taking ibuprofen (Motrin) for pain relief. Which information should the nurse provide the client about taking this medication?
- A. Take the medication with meals
- B. Take the medication with an antacid
- C. Report any changes in stool color to your healthcare provider
- D. Avoid taking aspirin while using this medication
Correct answer: C
Rationale: The correct answer is to instruct the client to report any changes in stool color to the healthcare provider. This is important because changes in stool color can indicate gastrointestinal bleeding, a serious side effect of nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen. Choice A is incorrect because while taking ibuprofen with meals can help reduce stomach upset, it is not the most crucial information to provide. Choice B is incorrect as taking ibuprofen with an antacid is not a standard recommendation. Choice D is also incorrect because while ibuprofen and aspirin are both NSAIDs, they can be taken together under certain circumstances, but it's important to be cautious and follow healthcare provider recommendations.
5. A couple has been trying to conceive for nine months without success. Which information obtained from the clients is most likely to have an impact on the couple's ability to conceive a child?
- A. Both partners have a daily exercise regimen that includes running four miles each morning.
- B. The couple has a history of having sexual intercourse 2 to 3 times per week.
- C. The woman's menstrual period occurs every 35 days.
- D. They use lubricants with each sexual encounter to decrease friction.
Correct answer: D
Rationale: Using lubricants during sexual encounters can potentially impact the couple's ability to conceive a child. Some lubricants may contain substances that are spermicidal or alter the vaginal environment, affecting sperm motility and fertility.
