NCLEX RN Predictor Exam
1. A healthcare professional is considering which patient to admit to the same room as a patient who had a liver transplant 3 weeks ago and is now hospitalized with acute rejection. Which patient would be the best choice?
- A. Patient who is receiving chemotherapy for liver cancer
- B. Patient who is receiving chemotherapy for lung cancer
- C. Patient who has a wound infection after cholecystectomy
- D. Patient who requires pain management for chronic pancreatitis
Correct answer: D
Rationale: The patient with chronic pancreatitis is the best choice to admit to the same room as a patient who had a liver transplant and is experiencing acute rejection. This is because the patient with chronic pancreatitis does not pose an infection risk to the immunosuppressed patient who had a liver transplant. On the other hand, patients receiving chemotherapy for cancer or those with wound infections are at risk for infections, which could endanger the immunosuppressed patient with acute rejection.
2. In the Gram Stain procedure, which component acts as the mordant?
- A. Crystal violet
- B. Methyl alcohol
- C. Iodine
- D. Safranin
Correct answer: C
Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
3. Rales and rhonchi are frequently noted during an examination of lung sounds. What is the difference between the two?
- A. Rales are louder.
- B. Rhonchi are noted only in infants.
- C. Rales occur on inspiration, rhonchi on expiration.
- D. Rales are noted only in infants.
Correct answer: C
Rationale: The correct answer is that rales occur on inspiration, while rhonchi occur on expiration. Rales are typically heard during inhalation when there is fluid in the alveoli or air passages. Rhonchi, on the other hand, are caused by air passing through obstructed airways during exhalation due to secretions in the respiratory tract. Choice A is incorrect because the loudness of the sounds is not the primary distinguishing factor between rales and rhonchi. Choice B is incorrect as rhonchi can be heard in individuals beyond infancy. Choice D is incorrect as rales can be present in patients of various age groups, not just infants.
4. Which brain structure serves as the heat-regulating center?
- A. Hypothalamus
- B. Pituitary Gland
- C. Pons
- D. Medulla Oblongata
Correct answer: A
Rationale: The correct answer is the Hypothalamus. The hypothalamus is responsible for regulating body temperature, ensuring it stays within a narrow range. Moreover, the hypothalamus controls various essential bodily functions, such as hunger, thirst, and circadian rhythms. Choices B, C, and D are incorrect because the Pituitary Gland primarily produces and releases hormones, the Pons is involved in functions like sleep, respiration, and bladder control, and the Medulla Oblongata controls vital functions like breathing and heart rate, but not body temperature regulation.
5. What does an individual who believes in the magicoreligious theory of illness and disease think is the cause of illness?
- A. Germs and viruses
- B. Supernatural forces
- C. Eating imbalanced (hot/cold) foods
- D. Imbalance within his or her spiritual nature
Correct answer: B
Rationale: Individuals who adhere to the magicoreligious theory of illness and disease attribute the cause of illness to supernatural forces. In this perspective, the world is perceived as governed by supernatural forces that influence the well-being of individuals. The belief is that these forces can bring about both good and evil outcomes. Choices A, C, and D are incorrect. Germs and viruses are associated with the biomedical theory of illness. Eating imbalanced hot or cold foods is linked to the yin/yang naturalist theory. Imbalance within one's spiritual nature is not a recognized cause of illness in any of the established theories of illness.
