ATI RN Custom Exams Set 1
1. The nurse is administering a beta blocker to the client diagnosed with essential hypertension. Which data would cause the nurse to question administering the medication?
- A. The client’s BP is 110/70
- B. The client’s potassium level is 3.4 mEq/L
- C. The client has a barky cough
- D. The client’s apical pulse is 56
Correct answer: D
Rationale: The correct answer is D. A beta blocker should be withheld if the apical pulse is below 60, as it can further decrease the heart rate. Choice A is not a reason to question administering a beta blocker as the blood pressure is within normal range. Choice B is not directly related to the administration of a beta blocker. Choice C may indicate a potential adverse effect of another medication, but it does not specifically warrant questioning the administration of the beta blocker.
2. Employees are eligible to take a leave of absence if they have worked for the employer for at least: (EXCEPT)
- A. At least 1,250 hours during the previous 12 months.
- B. At least 12 months.
- C. At least six months.
- D. At a work site with 50 employees within a 75-mile radius.
Correct answer: C
Rationale: Employees are eligible to take a leave of absence if they have worked for the employer for at least 12 months, have worked at least 1,250 hours during the previous 12 months, and are at a work site with 50 or more employees, or at a site where 50 workers are employed within 75 miles of the work site. The statement 'At least six months' is incorrect as the requirement is for 12 months of work to be eligible for a leave of absence.
3. What is the priority lab value to monitor in a patient with HIV?
- A. CD4 T-cell count 180 cells/mm3
- B. White blood cell count 4,500/mm3
- C. Potassium levels 3.5-5.0 mEq/L
- D. Hemoglobin levels below 12g/dL
Correct answer: A
Rationale: The correct answer is A: CD4 T-cell count 180 cells/mm3. Monitoring the CD4 T-cell count is crucial in patients with HIV to assess the status of their immune system. A CD4 count of 180 cells/mm3 indicates severe immunocompromise and a high risk of opportunistic infections. This value is used to guide treatment decisions and assess the need for prophylaxis against specific infections. Choices B, C, and D are incorrect because monitoring white blood cell count, potassium levels, and hemoglobin levels, although important in HIV patients, are not as crucial as monitoring the CD4 T-cell count for assessing immune function and disease progression.
4. Who believed that complex mental activities have their origins in social interaction?
- A. Jean Piaget
- B. Renée Baillargeon
- C. Noam Chomsky
- D. Lev Vygotsky
Correct answer: D
Rationale: The correct answer is Lev Vygotsky. Vygotsky emphasized the role of social interaction and cultural tools in the development of higher cognitive functions. Jean Piaget focused more on individual cognitive development stages, Renée Baillargeon is known for her work in infant cognition and object permanence, and Noam Chomsky is renowned for his theories in linguistics and the study of language.
5. A client with chronic kidney disease has arterial blood gas values being reviewed by a nurse. Which of the following sets of values should the nurse expect?
- A. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg
- B. pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg
- C. pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg
- D. pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg
Correct answer: A. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg
Rationale: In chronic kidney disease, metabolic acidosis is common due to impaired kidney function leading to reduced bicarbonate excretion. The correct values indicating metabolic acidosis in this scenario are a low pH (acidosis), low bicarbonate (HCO3-) level, and low PaCO2 (compensation through respiratory alkalosis). Therefore, the expected values for a client with chronic kidney disease would be pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg, as depicted in choice A.
