NCLEX-PN Quizlet 2023 Questions
Extract:
Question 1 of 5
A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63 mmHg, HCO3 23, and oxygenation saturation (SaO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?
Correct Answer: D
Rationale: A combined low PO2 and low SaO2 indicate hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low due to hypoxia stimulating hyperventilation, but the given ABG values specifically point to hypoxia as the primary issue.
Question 2 of 5
What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36mmHg, and HCO3 24 mEq/L?
Correct Answer: B
Rationale: The correct answer is 'homeostasis.' These ABG values fall within normal ranges, indicating a state of balance in the body's acid-base levels.
Choices A, C, and D are incorrect as the ABG values provided do not point towards metabolic alkalosis, respiratory acidosis, or respiratory alkalosis. Instead, the values reflect a state of equilibrium where pH, PO2, PCO2, and HCO3 levels are within the normal range.
Question 3 of 5
Which of the following infant behaviors demonstrates the concept of object permanence?
Correct Answer: B
Rationale: Object permanence occurs when the infant learns that something or someone still exists even though they might not be able to see it or them. This typically develops between 9 and 10 months of age. The correct answer, 'The infant looks at the floor to find a toy that he was playing with and dropped,' demonstrates object permanence as the infant understands that the toy still exists even though it is temporarily out of sight.
Choices A and C do not directly relate to object permanence as the behaviors described do not necessarily indicate an understanding of objects existing when out of sight.
Choice D is incorrect as participating in a game of patty-cake does not involve demonstrating object permanence. Peek-a-boo is a more suitable example of a game that demonstrates object permanence, as the infant continues to look for the hidden face, understanding that it still exists even though temporarily unseen.
Question 4 of 5
Which of the following diseases or conditions is least likely to be associated with an increased potential for bleeding?
Correct Answer: C
Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding. Pernicious anemia results from vitamin B12 deficiency due to a lack of intrinsic factor, leading to faulty absorption from the gastrointestinal tract. While pernicious anemia can lead to other health issues, bleeding tendencies are not a primary concern. Metastatic liver cancer (choice
A) can cause liver dysfunction leading to decreased synthesis of clotting factors, increasing the risk of bleeding. Gram-negative septicemia (choice
B) can lead to disseminated intravascular coagulation (DI
C) causing excessive bleeding. Iron-deficiency anemia (choice
D) can result in microcytic hypochromic red blood cells, which can impair oxygen transport and lead to tissue hypoxia, but it is not directly associated with a significant potential for bleeding.
Question 5 of 5
A client, age 28, was recently diagnosed with Hodgkin's disease. After staging, therapy is planned to include combination radiation therapy and systemic chemotherapy with MOPP"?nitrogen mustard, vincristine (Onconvin), prednisone, and procarbazine. In planning care for this client, the nurse should anticipate which of the following side effects to contribute to a sense of altered body image?
Correct Answer: B
Rationale: The correct answer is B: alopecia. Chemotherapy drugs like vincristine and nitrogen mustard commonly cause hair loss (alopecia), which can significantly impact body image. While a Cushingoid appearance can be a side effect of long-term steroid use, it is not typically associated with the chemotherapy regimen mentioned. Temporary or permanent sterility can result from chemotherapy, affecting fertility but not directly contributing to altered body image. Pathologic fractures are not commonly linked to Hodgkin's disease or its treatment, unlike alopecia which is a well-known side effect.
