Adult Health Exam 1 Questions
Question 1 of 5
The healthcare provider prescribes erythromycin (Ilosone) 300 mg PO QID. The medication label reads, 'Ilosone 100mg/5mL.' How many mL should the nurse administer at each dose?
Correct Answer: A
Rationale: To determine the volume of medication needed for a 300 mg dose of Ilosone (100mg/5mL), we set up a proportion: 100 mg is to 5 mL as 300 mg is to x mL. Cross-multiplying, we get x = (300*5)/100 = 15 mL. Therefore, the nurse should administer 15 mL at each dose. Choice B (10 mL) is incorrect as it does not reflect the correct calculation based on the medication concentration. Choices C (20 mL) and D (5 mL) are also incorrect as they do not accurately calculate the volume required for the prescribed dose.
Question 2 of 5
The nurse is caring for a client postoperatively following a hip replacement. Which intervention is most important to prevent dislocation of the prosthesis?
Correct Answer: B
Rationale: Maintaining hip abduction with pillows is crucial in preventing dislocation of the hip prosthesis postoperatively. This position helps keep the hip joint stable and reduces the risk of the prosthesis becoming displaced. Choices A, C, and D are not as effective in preventing dislocation. Keeping the client in a low Fowler's position does not provide the necessary hip support. While early ambulation is important for circulation and preventing complications, maintaining hip abduction is more specific to preventing prosthesis dislocation. Placing the client in a prone position can increase the risk of hip prosthesis dislocation due to the extreme positioning.
Question 3 of 5
A client with heart failure is prescribed a low-sodium diet. The nurse notices the client's meal tray contains high-sodium foods. What action should the nurse take?
Correct Answer: B
Rationale: The correct action for the nurse to take in this situation is to replace the high-sodium meal with a low-sodium option. This immediate intervention ensures that the client adheres to the prescribed low-sodium diet, crucial for managing heart failure and preventing fluid retention. Educating the client (Choice A) about the diet is important but not as urgent as ensuring they receive the correct meal. Reporting the error to the dietary department (Choice C) can be done after addressing the immediate issue. Encouraging the client to avoid high-sodium foods (Choice D) is not as effective as replacing the current meal with a suitable alternative.
Question 4 of 5
What safety measure should be implemented when administering chemotherapy?
Correct Answer: A
Rationale: When administering chemotherapy, it is crucial to use protective gloves and a gown to protect against exposure to hazardous drugs that can be harmful through skin contact. Choice B is incorrect because chemotherapy medication should be prepared in a designated area to prevent contamination and ensure accurate preparation. Choice C is incorrect as chemotherapy should be administered at the appropriate rate to ensure patient safety and avoid adverse effects. Choice D is incorrect as verifying client identifiers is important for medication administration in general but not a specific safety measure related to chemotherapy administration.
Question 5 of 5
A client is admitted with a diagnosis of myocardial infarction (MI). Which intervention is a priority during the acute phase?
Correct Answer: A
Rationale: During the acute phase of a myocardial infarction (MI), the priority intervention is to administer morphine for pain relief. Morphine not only alleviates pain but also reduces myocardial oxygen demand, which is crucial in the management of MI. Encouraging the client to perform isometric exercises (choice B) can increase myocardial oxygen demand and should be avoided during the acute phase. Positioning the client flat in bed (choice C) may worsen symptoms by increasing venous return and workload on the heart. Restricting fluid intake (choice D) is not a priority intervention during the acute phase of MI; maintaining adequate hydration is important for organ perfusion.
