HESI RN CAT Exam Quizlet
1. The nurse is caring for a client who is receiving total parenteral nutrition (TPN) via a central venous catheter. Which assessment finding indicates a complication related to the TPN?
- A. Blood glucose level of 180 mg/dl
- B. Serum potassium level of 4.0 mEq/L
- C. Weight gain of 2 pounds in 24 hours
- D. White blood cell count of 7000/mm3
Correct answer: C
Rationale: A weight gain of 2 pounds in 24 hours is concerning as it indicates fluid retention, a potential complication of TPN leading to fluid overload. Elevated blood glucose levels (Choice A) are expected in TPN, serum potassium levels (Choice B) are within the normal range, and a white blood cell count (Choice D) of 7000/mm3 is also normal. Therefore, the correct answer is C, as it suggests a complication related to TPN.
2. The public health nurse is preparing to administer flu vaccines at a community center. Which group should the nurse prioritize for vaccination?
- A. children under 5 years old
- B. adults aged 50-65
- C. pregnant women
- D. healthcare workers
Correct answer: C
Rationale: Pregnant women should be prioritized for flu vaccination as they are at higher risk for complications from the flu. During pregnancy, changes in the immune, heart, and lung functions make pregnant women more susceptible to severe illness from the flu. Vaccinating pregnant women not only protects them but also provides passive immunity to their newborns. Children under 5, adults aged 50-65, and healthcare workers are important groups for vaccination but do not have the same level of increased risk for flu complications as pregnant women.
3. A child is admitted to the pediatric unit with a diagnosis of suspected meningococcal meningitis. Which admission orders should the nurse do first?
- A. Institute seizure precautions
- B. Monitor neurologic status every hour
- C. Place in respiratory/secretion precautions
- D. Cefotaxime IV 50 mg/kg/day divided q6h
Correct answer: C
Rationale: The correct answer is to place the child in respiratory/secretion precautions first. Meningococcal meningitis is highly contagious, and respiratory precautions are essential to prevent the spread of the infection. Seizure precautions may be necessary but are not the priority upon admission. Monitoring neurologic status is important but not the initial action needed. While antibiotic therapy like Cefotaxime is crucial, implementing isolation precautions to prevent transmission takes precedence in this situation.
4. A healthcare professional is monitoring a client who is receiving intravenous amphotericin B. Which of the following should prompt the healthcare professional to notify the healthcare provider immediately?
- A. Fever
- B. Headache
- C. Nausea
- D. Oliguria
Correct answer: D
Rationale: Amphotericin B is known to cause nephrotoxicity, which can lead to kidney damage. Oliguria, which is decreased urine output, is a concerning sign of kidney dysfunction and should be reported promptly to the healthcare provider to prevent further complications. Fever, headache, and nausea are common side effects of amphotericin B but are not as critical as oliguria in indicating potential kidney damage.
5. What percentage of the parents' offspring is predicted to have a cleft chin if one parent carries the recessive gene for a cleft chin (c) while the other parent does not?
- A. 25%
- B. 50%
- C. 0%
- D. 75%
Correct answer: C
Rationale: The correct answer is C (0%). If one parent carries the recessive gene for a cleft chin while the other parent does not carry it, none of their offspring is predicted to have a cleft chin. This is because the cleft chin trait is recessive, so for an offspring to express this trait, they would need to inherit the gene from both parents. In this scenario, none of the offspring will inherit the recessive gene from both parents, so the percentage of offspring predicted to have a cleft chin is 0%. Choices A, B, and D are incorrect because in this situation, the offspring will not express the cleft chin phenotype, although they could be carriers of the recessive gene.
