HESI LPN
HESI CAT Exam
1. A group of nurses implemented a pilot study to evaluate a proposed evidence-based change to providing client care. Evaluation indicates successful outcomes, and the nurses want to integrate the change throughout the facility. Which action should be taken? (Select all that apply)
- A. Invite data review by the quality improvement department
- B. Submit a sentinel event report to the research committee
- C. Propose clinical practice guidelines to the nursing committee
- D. Arrange in-service training through the educational department
Correct answer: A
Rationale: Inviting data review by the quality improvement department is crucial to ensure the quality and efficacy of the proposed evidence-based change. This step allows for a comprehensive analysis of the data collected during the pilot study. Proposing clinical practice guidelines to the nursing committee is also essential for integrating the successful change into routine practice. In-service training through the educational department will help educate staff and ensure they are proficient in implementing the new practices. Submitting a sentinel event report to the research committee is not necessary in this scenario as the outcomes were successful, and there were no adverse events that would warrant such a report. Choices B, C, and D are not as relevant in this context compared to inviting data review by the quality improvement department, which is a crucial step in ensuring the success of the proposed change.
2. You are managing a 10-month-old infant who has had severe diarrhea and vomiting for 3 days and is now showing signs of shock. You have initiated supplemental oxygen therapy and elevated the lower extremities. En route to the hospital, you note that the child's work of breathing has increased. What must you do first?
- A. Lower the extremities and reassess the child
- B. Begin positive pressure ventilations and reassess the child
- C. Place a nasopharyngeal airway and increase the oxygen flow
- D. Listen to the lungs with a stethoscope for abnormal breath sounds
Correct answer: A
Rationale: In this scenario, the infant is showing signs of shock with increased work of breathing. Lowering the extremities helps improve venous return to the heart, cardiac output, and oxygenation by reducing the pressure on the diaphragm. This action can alleviate the respiratory distress and is a critical step to take in a child with signs of shock. Beginning positive pressure ventilations (Choice B) should be considered if the infant's respiratory distress worsens despite lowering the extremities. Placing a nasopharyngeal airway and increasing oxygen flow (Choice C) may not directly address the increased work of breathing or the underlying shock condition. Listening to the lungs with a stethoscope (Choice D) may provide information on lung sounds but does not address the immediate need to improve breathing in a child with signs of shock.
3. Twenty-four hours after starting to take oral penicillin for strep throat, a client calls the nurse to report the onset of a rash on the chest. What action should the nurse implement?
- A. Instruct the client to discontinue the penicillin immediately
- B. Instruct the client regarding the use of topical analgesic cream PRN
- C. Question the client about any other related symptoms
- D. Reinforce the need to take all doses of the penicillin
Correct answer: A
Rationale: In this scenario, the client has developed a rash after starting oral penicillin, which can indicate an allergic reaction. It is crucial for the nurse to instruct the client to discontinue the penicillin immediately. Continuing the medication can potentially lead to severe allergic reactions. Instructing about topical analgesic cream or questioning about other related symptoms may delay appropriate action in case of a severe allergic reaction. Reinforcing the need to complete all doses is not appropriate when an allergic reaction is suspected, as safety takes precedence over completing the antibiotic course.
4. Jansen is receiving metformin (Glucophage). What will be the best plan of the nurse with regard to patient education with this drug? Select one that does not apply.
- A. It stimulates the pancreas to produce more insulin.
- B. It must be taken after meals.
- C. It decreases sugar production in the liver.
- D. It inhibits absorption of carbohydrates.
Correct answer: A
Rationale: The correct choice that does not apply is A. Metformin does not stimulate the pancreas to produce more insulin; instead, it works by decreasing sugar production in the liver, inhibiting carbohydrate absorption, and reducing insulin resistance. It is recommended to take metformin with meals to reduce gastrointestinal side effects. Option B is incorrect as metformin is usually taken with meals. Option D is also incorrect as metformin does not inhibit the absorption of carbohydrates.
5. Which of the following pairs of bases is present in the rungs of the ladder-like structure of deoxyribonucleic acid (DNA)?
- A. Cytosine with guanine.
- B. Rhodamine with biotin.
- C. Diaminopurine with ribozyme.
- D. Serine with tyrosine.
Correct answer: A
Rationale: The correct answer is A: Cytosine with guanine. In the DNA double helix, cytosine always pairs with guanine forming a base pair, and adenine pairs with thymine. These complementary base pairs form the rungs of the ladder-like structure of DNA. Choice B, Rhodamine with biotin, is incorrect as they are not base pairs found in DNA. Choice D, Serine with tyrosine, is incorrect as they are amino acids, not DNA bases. Choice C, Diaminopurine with ribozyme, is also incorrect as ribozyme is an enzyme, not a base, and diaminopurine is not one of the standard bases found in DNA.
