HESI PN Exit Exam 2024 Quizlet
1. Which is the most important safety measure when administering a medication through a patient’s central venous catheter (CVC)?
- A. Using a sterile technique
- B. Ensuring correct placement of the CVC
- C. Flushing the CVC with saline after administration
- D. Monitoring for signs of infection
Correct answer: B
Rationale: The most important safety measure when administering a medication through a patient’s central venous catheter (CVC) is ensuring the correct placement of the CVC. This is crucial to prevent complications such as extravasation, infection, or improper drug delivery. While using a sterile technique, flushing the CVC with saline after administration, and monitoring for signs of infection are all important aspects of CVC care, ensuring the correct placement of the catheter takes precedence as it directly impacts patient safety during medication administration.
2. A nurse is caring for a client who has a surgical wound. Which of the following laboratory values places the client at risk for poor wound healing?
- A. Serum albumin 3 g/dL
- B. Total lymphocyte count 2400/mm3
- C. HCT 42%
- D. HGB 16 g/dL
Correct answer: A
Rationale: The correct answer is A: Serum albumin 3 g/dL. Low levels of serum albumin indicate poor nutritional status and can impair wound healing. Total lymphocyte count, HCT, and HGB levels are not directly related to wound healing and do not pose a significant risk for poor wound healing in this context. Total lymphocyte count reflects the immune status, HCT measures the percentage of red blood cells in blood, and HGB measures the amount of hemoglobin in blood.
3. The healthcare provider is caring for a client with a suspected deep vein thrombosis (DVT). Which assessment finding should the healthcare provider report to the healthcare provider?
- A. Swelling and redness in the affected leg
- B. Pain in the affected leg
- C. Warmth and tenderness in the affected leg
- D. A positive Homans' sign
Correct answer: D
Rationale: A positive Homans' sign is a classic sign associated with deep vein thrombosis (DVT) and indicates the presence of a blood clot. This finding is crucial to report to the healthcare provider promptly for further evaluation and treatment. Swelling, redness, pain, warmth, and tenderness in the affected leg are common signs of DVT, but a positive Homans' sign specifically points towards a potential blood clot, making it the priority finding to be reported. Reporting other symptoms may also be important, but a positive Homans' sign is more specific to DVT and requires immediate attention.
4. When administering ceftriaxone sodium intravenously to a client before surgery, which assessment finding requires the most immediate intervention by the nurse?
- A. Headache
- B. Pruritus
- C. Nausea
- D. Stridor
Correct answer: D
Rationale: Stridor is a high-pitched, noisy breathing sound that can indicate a serious condition like airway obstruction or a severe allergic reaction, necessitating immediate intervention to maintain the client's airway and prevent further complications. While headache, pruritus, and nausea are important to assess and manage, they are not as immediately life-threatening as stridor, which requires prompt attention to prevent respiratory compromise.
5. When caring for a neonate with a suspected tracheoesophageal fistula, what nursing care should be included?
- A. Elevating the head but giving nothing by mouth
- B. Elevating the head for feedings
- C. Feeding glucose water only
- D. Avoiding suctioning unless the infant is cyanotic
Correct answer: A
Rationale: In a neonate with a suspected tracheoesophageal fistula, elevating the head but giving nothing by mouth is crucial to prevent aspiration. Placing the neonate in a semi-upright position helps reduce the risk of reflux and aspiration of gastric contents into the lungs. Elevating the head for feedings (Choice B) would still pose a risk of aspiration as the neonate may aspirate during feeding. Feeding glucose water only (Choice C) is not appropriate and does not address the risk of aspiration associated with a tracheoesophageal fistula. Avoiding suctioning unless the infant is cyanotic (Choice D) is incorrect because suctioning may be necessary for maintaining airway patency, regardless of cyanosis, in a neonate with a suspected tracheoesophageal fistula.
