What is the proper hand position when performing chest vibration?

Correct Answer: B

Rationale: The correct hand position for performing chest vibration is to spread the fingers. This allows for a larger surface area of contact with the chest, promoting effective transmission of vibrations to loosen chest secretions. Flattening the hands would reduce the effectiveness of the vibrations by limiting contact area. Cupping the hands creates a smaller contact area and may concentrate the pressure too much in one spot, potentially causing discomfort or injury. Therefore, spreading the fingers is the optimal hand position for chest vibration technique.

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Preventing infiltration of calcium is crucial to avoid tissue necrosis and sloughing. 2. Infiltration of calcium can lead to severe tissue damage and potential harm to the patient. 3. Monitoring for signs of infiltration during administration of electrolyte solutions is essential. 4. Administering calcium-containing solutions cautiously can prevent serious complications. 5. Ensuring proper placement of the IV line and monitoring for any signs of infiltration is key. Summary: A: Infusing hypertonic solutions rapidly can lead to adverse effects, such as fluid overload. B: Limiting potassium to 80 mEq per liter is important, but not directly related to preventing calcium infiltration. D: Reevaluating digitalis dosage is important in clients receiving electrolyte solutions but not directly related to preventing calcium infiltration.

Correct Answer: A

Rationale: The correct answer is A: Creatinine. Creatinine is a waste product produced by muscles and excreted by the kidneys. An elevated creatinine level indicates impaired kidney function, making it a key indicator for early detection of renal failure. Blood urea nitrogen (BUN) can also be elevated in renal failure, but creatinine is a more specific and sensitive marker. Sodium and potassium levels are not directly related to renal failure detection.

Correct Answer: A

Rationale: The correct answer is A: Administer nitroglycerin. This is the first step in the care of a client with acute chest pain because nitroglycerin helps dilate blood vessels, improving blood flow to the heart. This can relieve chest pain associated with angina or heart attack. Administering aspirin (choice B) is important as well, but nitroglycerin is prioritized due to its immediate effect in reducing chest pain. Administering opioids (choice C) and morphine (choice D) are not recommended as first-line treatments for acute chest pain, as they can mask symptoms and delay the diagnosis of potentially life-threatening conditions.

Correct Answer: D

Rationale: The correct answer is D. When a client refuses medication, the nurse should document the refusal for legal and communication purposes. Informing the healthcare provider ensures ongoing assessment and potential alternatives. Choice A lacks communication with the healthcare team. Choice B may not address the underlying issue. Choice C assumes alternative treatment is necessary without further evaluation.
