Nursing Elites

1. A nurse is preparing to perform a sterile dressing change for a client who has a surgical wound. Which of the following actions should the nurse take to prevent contamination during the dressing change?

• A. Use sterile gloves only as necessary
• B. Restart the procedure if the sterile solution splashes onto the sterile field while pouring the solution into the dressing tray
• C. Keep the dressing tray on a nearby surface
• D. Avoid speaking during the procedure

Correct answer: B

Rationale: The correct action to prevent contamination during a sterile dressing change is to restart the procedure if the sterile solution splashes onto the sterile field while pouring the solution into the dressing tray. Any contact with the sterile field by non-sterile items makes the field contaminated and requires restarting the procedure to maintain sterility. Choice A is incorrect because sterile gloves should always be used during a sterile procedure to prevent contamination. Choice C is incorrect as the dressing tray should be placed on a sterile surface, not on the client's bed, to maintain sterility. Choice D is also incorrect as talking during the procedure does not necessarily lead to contamination if proper aseptic technique is maintained.

2. A healthcare professional is verifying nasogastric tube placement by the pH of aspirated gastric fluid. Which of the following pH values provides a good indication of correct tube placement?

• A. 2
• B. 5
• C. 7
• D. 9

Correct answer: A

Rationale: The correct answer is A: '2'. Gastric contents with a pH between 0 and 4 provide a good indication of appropriate tube placement. A pH of 2 is within this range, indicating that the tube is correctly placed in the stomach. Choices B, C, and D are incorrect because a pH of 5, 7, or 9 does not fall within the expected acidic pH range of gastric fluid.

3. While caring for a client receiving nitroglycerin for chest pain, which of the following side effects should the nurse monitor for?

• A. Hypotension
• B. Tachycardia
• C. Bradycardia
• D. Hyperglycemia

Correct answer: A

Rationale: Corrected Rationale: Nitroglycerin is known to cause hypotension due to its vasodilating effect, which can lead to low blood pressure. Therefore, the nurse should closely monitor the client for signs of hypotension such as dizziness, light-headedness, or weakness. Tachycardia (increased heart rate), bradycardia (decreased heart rate), and hyperglycemia (high blood sugar) are not typically associated with nitroglycerin use and are less likely to be side effects that the nurse needs to monitor for in this scenario.

4. A nurse is reviewing the laboratory results for a client who has a prescription for filgrastim. The nurse should recognize that an increase in which of the following values indicates a therapeutic effect of this medication?

• A. Erythrocyte count
• B. Neutrophil count
• C. Lymphocyte count
• D. Thrombocyte count

Correct answer: B

Rationale: Filgrastim is used to increase neutrophil production in clients undergoing chemotherapy or with bone marrow suppression. A rise in neutrophil count indicates the medication is working effectively to boost immune response. Choices A, C, and D are incorrect as filgrastim primarily targets neutrophils, not erythrocytes, lymphocytes, or thrombocytes.

5. A client with osteoporosis is being taught by a nurse about dietary changes. Which of the following food choices should the nurse recommend to promote bone health?

• A. Leafy green vegetables
• B. Red meat
• C. Fortified orange juice
• D. Whole grains

Correct answer: C

Rationale: The correct answer is C: Fortified orange juice. Fortified orange juice is often supplemented with calcium and vitamin D, both of which are essential for bone health and the prevention of osteoporosis. Leafy green vegetables (choice A) are good for overall health but may not provide sufficient calcium for bone health. Red meat (choice B) is a source of protein but is not a primary source of calcium. Whole grains (choice D) are beneficial for fiber intake but do not contain significant amounts of calcium or vitamin D necessary for bone health.
