1. Which of the following vaccines is not done by intramuscular (IM) injection?
- A. Measles vaccine C. Hepa-B vaccine
- B. DPT D. Tetanus toxoids
- C.
- D.
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
2. In females, the twenty-third pair of chromosomes is labeled as __________.
- A. an autosome
- B. dizygotic
- C. XX
- D. XY
Correct answer: C
Rationale: In females, the twenty-third pair of chromosomes is indeed labeled as XX. This pair of chromosomes determines the biological sex of females. Choice A, 'an autosome,' is incorrect as autosomes refer to the non-sex chromosomes. Choice B, 'dizygotic,' is incorrect as it relates to twins. Choice D, 'XY,' is incorrect as it represents the chromosome pair found in males.
3. A nurse is caring for a client who has diarrhea due to shigella. Which of the following precautions should the nurse take?
- A. Wear gloves only
- B. Wear a mask
- C. Wash hands before and after client care
- D. Use an N95 respirator
Correct answer: C
Rationale: The correct precaution for a nurse caring for a client with shigella-induced diarrhea is to wash hands before and after client care. Shigella is a highly contagious bacterium that spreads through contaminated food, water, or contact with infected individuals. While wearing gloves is important when directly handling bodily fluids, hand hygiene is crucial in preventing the transmission of the infection. Wearing a mask or using an N95 respirator is not necessary for preventing the spread of shigella, as it primarily spreads through the fecal-oral route rather than through respiratory droplets.
4. Observations of imprinting led to which major concept in human development?
- A. adaptation
- B. equilibrium
- C. the critical period
- D. classical conditioning
Correct answer: C
Rationale: Observations of imprinting in animals, such as ducklings following the first moving object they see after hatching, led to the major concept of the critical period in human development. The critical period is a specific time frame during which an organism must experience certain stimuli to develop properly. This concept has been influential in understanding various aspects of human development, such as language acquisition and social attachment. Choices A, B, and D are incorrect. Adaptation refers to adjusting to the environment, equilibrium is about balance in cognitive processes, and classical conditioning is a learning process associated with behaviorism, none of which directly relate to the concept derived from imprinting observations.
5. Studies suggest that leukoplakia is resolved by excess vitamin A (a fat-soluble vitamin), retinoids, and beta-carotene. Leukoplakia is a white plaque that forms on oral mucous membranes.
- A. Both statements are true.
- B. Both statements are false.
- C. The first statement is true; the second is false.
- D. The first statement is false; the second is true.
Correct answer: B
Rationale: Both statements are false. Studies suggest that leukoplakia, a white plaque that forms on oral mucous membranes, can be resolved by vitamin A, retinoids, and beta-carotene. Despite the potential to resolve leukoplakia, relapse is common. Also pertinent, evidence does not indicate that any of these nutrients prevent malignant transformation. The extract provided clarifies that leukoplakia is a white plaque, not an erythematous lesion, and that vitamin A, retinoids, and beta-carotene can help resolve it.
