1. The actual sets of traits that people exhibit are called their genotypes.
- A. TRUE
- B. FALSE
- C. Possibly
- D. Always
Correct answer: B
Rationale: The actual sets of traits that people exhibit are called phenotypes, not genotypes. Genotypes refer to the genetic makeup of an individual.
2. A client with a body mass index (BMI) of 30 is seeking advice on the initial approach to a weight loss plan. What action should the nurse recommend?
- A. Plan meals with low carbohydrates and high protein
- B. Engage in strenuous activity for an hour daily
- C. Keep a record of daily food and beverage intake
- D. Participate in a group exercise class three times a week
Correct answer: C
Rationale: Keeping a food diary is an essential practice when starting a weight loss plan as it helps in tracking calorie intake, identifying eating patterns, and making informed decisions about dietary changes. Planning meals with low carbohydrates and high protein (Choice A) can be beneficial for some individuals, but keeping a food diary is more foundational. Engaging in strenuous daily activity (Choice B) may not be sustainable for everyone and could lead to burnout or injuries. Participating in a group exercise class (Choice D) is beneficial for fitness but may not address dietary habits, which are crucial for weight loss.
3. Which of the following processes happen during mitosis?
- A. Strands of deoxyribonucleic acid (DNA) break apart.
- B. Adenine combines with its appropriate partner, cytosine.
- C. Sperm and ova cells are created.
- D. Twenty-three chromosomes are created.
Correct answer: A
Rationale: The correct process that happens during mitosis is the breaking apart, replication, and division of DNA strands into two new cells, each with the same number of chromosomes as the original cell. Choice B is incorrect because it describes base pairing in DNA, not a process specific to mitosis. Choice C is incorrect as the creation of sperm and ova cells is related to meiosis, not mitosis. Choice D is incorrect because chromosomes are not created during mitosis; they are replicated and divided equally between the daughter cells.
4. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?
- A. They involve antigen-antibody complexes.
- B. They are mediated by T cells and do not involve antibodies.
- C. They result in immediate allergic reactions.
- D. They are the least severe form of hypersensitivity.
Correct answer: B
Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.
5. A client with asthma is receiving albuterol (Proventil). The nurse should monitor the client for which of the following side effects?
- A. Hypoglycemia
- B. Hyperkalemia
- C. Tachycardia
- D. Hypotension
Correct answer: C
Rationale: The correct answer is C: Tachycardia. Albuterol can cause tachycardia as a side effect due to its stimulant effect on the heart. It acts as a beta-2 adrenergic agonist, leading to increased heart rate. Hypoglycemia (choice A) is not a common side effect of albuterol. Hyperkalemia (choice B) is also not typically associated with albuterol use. Hypotension (choice D) is less likely to occur as albuterol usually causes tachycardia rather than hypotension.
